Honda Reinvents Regenerative Braking for Fit EV

As we discussed in October, the secret sauce of a good electric car is not how it accelerates, but how it brakes. Yesterday, I had two short rides in the Honda Fit EV at the company’s Twin Ring Motegi complex north of Tokyo—prior to my visit to the 2011 Tokyo Motor Show today. My driving impressions from behind the wheel are embargoed until Dec. 5—but I’m free to report on my discussion with Kunimichi Hatano, the engineer who created Honda’s new regenerative braking system.

Honda’s strategy rests somewhere between what Ford will do with the Focus Electric—make it feel like any conventional car without special modes or gears—and BMW’s strategy. Electric Bimmers will brake in an aggressive and distinct way, according to Aaron Singer, BMW product strategy manager. The Fit EV's braking is perhaps most similar to the one found in the Nissan LEAF, with a couple of key exceptions. Honda’s Mr. Hatano explained that the goal is to make the brake feel comfortable and familiar—yet the Fit EV will have a “B” gear, providing the driver the choice to engage an aggressive motor-only regen setting, as well as an “Econ” mode that removes regenerative braking in a coasting-type function. The current LEAF lacks such driver-managed controls.

Again, I can’t speak yet about the relative level of performance achieved when toggling between Normal, Sport and Econ modes. But what’s important here is the role that Honda’s new electro-servo brake system—the first of its kind—in yielding about 75 miles of real-world range, and123 miles of range (in the forgiving LA4 cycle). The Fit combines a 94 kW motor and 20 kWh battery pack. (Honda is not yet sharing details about the weight of the Fit EV, but it's bound to be lighter than the LEAF.)

So far, the Fit EV is the only Honda car that has been (ahem) fitted with the new system, but it is also slated to go into Honda’s upcoming Accord-sized plug-in hybrid—which I also was able to drive yesterday.

Here’s an excerpt from my conversation with Mr. Hatano.

Many EV drivers like very aggressive regenerative braking. Why not give a unique aggressive feel to regen braking in your electric vehicles?
Honda does not intend to reduce the amount of regenerative braking to achieve satisfactory brake feeling. Obviously, we want to recuperate as much energy as possible. But if you try to recuperate too much energy, you might destabilize the vehicle. The question is how much energy can we recuperate without going over the threshold of losing stability. You have to bear in mind that vehicles are driven under bad weather, in snow, and rain, and when the road surface might not be good. You have to make sure the regenerative braking doesn’t go beyond what is reasonable.

But it can feel different and still be safe, right?
Sure, some prefer a different feeling. Whatever kind of brake feel you want—whether it’s like normal gasoline-powered cars or different—that’s one subject. And the limit of regenerative braking is another subject. The limit is more about preserving stability. Because this is an electric braking system, you can fine-tune the taste in many different ways.

How is the electro-servo braking system different than its predecessors?
In our system, you have two different main parts. In the first part, you create the brake feel. This is quite common with other carmakers. The way our brakes feel might be different, but the system is not very different. However, what is different is the part that actuates the brakes. Traditional hydraulic brakes use a vacuum to activate the brake system, and then pump oil to press the pads against the rotor. A hybrid system may use solenoids. Our new system is different because the medium to apply the brakes is using an electric motor to directly drive the pump that serves the brake fluid.

What’s the advantage?
This system has very high accuracy. This means more efficiency. It’s more faithful to the brake input from the driver. [Honda estimates that the servo-based system increasing efficiency by at least 5 percent.]

When you take your foot off the accelerator, you immediately have a little bit of regenerative braking. Then, you put your foot on the brake—and if you look at the curve on the hydraulic system, it goes up very sharply. But if you look at the yellow zone in the graph, [in the old system] the regeneration doesn’t go up as sharply and it’s delayed. The idea of the new system is to bring the regenerative yellow zone closer to the hydraulic response.

The first part of the slope is very similar to the hydraulic. Then, as you start reaching the regeneration limit, the slope gradually slows down a little and reaches the limit after what the hydraulic system can do. After that, you can keep regeneration system at the highest level longer than the current system. And just before you stop, the drop is even sharper than the old regeneration system.

All of this is possible because of the servo system? Could you have done this just with calibration?
No, you need the accuracy to achieve it.

Does the increased regenerative braking mean slowing down faster?
The braking distance itself is not shortened by this alone. The braking distance is determined by the weight of the vehicle, the speed, and the amount of energy you take out either by regenerative braking or traditional braking, and the tire grip. This system doesn’t mean that you’ll shorten the braking distance. That depends on the caliper or other brake operations.
How does the “B” gear mode affect regenerative braking?

B is for higher regeneration only when the throttle is off. If you are in B mode, it's only regenerating energy through negative torque at the motor level. [There’s no use of the brakes.]

And what’s the effect of Econ mode?
In the econ mode, on the contrary, it reduces the engine brake effect so the car can coast. The idea is to reduce the up and down demands on the engine—by having less engine braking, which means you don’t lose as much as speed.

The B mode is made to suit certain driving situations, like when you’re going down a slope and you see a red light at the end. You put it in B to recuperate energy, so you slow down, which is fine. And if you see the light changes to green, you just put it back into D. It’s a question of responding to all possible driving situations.

Postscript
I can guess that many PluginCars.com readers will like the sound of Honda’s approach—but the nagging question remains: Why is the company only producing 1,100 Fit EVs over the next three years, and not allowing customers who might fall in love with the car the ability to keep it beyond the lease period? Company officials here repeated the same “one step at a time” message—that they want to learn as much as possible from the first customers in order to refine the car into the best possible EV.

I spoke with multiple high-ranking executives to encourage them to reconsider—especially if it looks like the Fit EV is a winner. It’s too early to know, but I have a glimmer of hope that Honda could reconsider its lease-only approach and/or increase production. If indeed the Fit EV represents an improvement in electric car braking, along with controls for higher regen and coasting, it will only be a matter of time before competitors offer similar features in their battery-powered cars. Honda's apparent technology and feature advantage could evaporate in three years, just as the company is collecting and processing feedback from the 1,100 Fit EV leaseholders who have the distinction of driving the car. That would be a shame.

Try, try, again: Another Honda Accord hybrid on the way

Honda just introduced a bevy of energy-frugal cars at the Tokyo Motor Show and vowed to cut carbon emissions by 30% from year 2000 levels on all its vehicles by 2020.

But perhaps more interesting were remarks to reporters indicating that another Accord hybrid is on the way, wire services reported. The model was discontinued in the U.S. after poor sales, mostly because it didn't save much gas, as it modified a V-6, instead of a four-cylinder, engine.

"For such a future, the most important challenge we need to address right now is the improvement of the efficiency of gasoline and diesel-powered internal combustion engines," said CEO Takanobu Ito.

To get there, he says he hopes to modify gas and diesel engines and combine them with continuously variable transmissions, or CVTs.

As a down payment on Honda's greenness, he showed off the EV-ster concept, an electric rear-wheel-drive two-seater convertible sports car. He says it has an electric range of about 80 miles and is steered with a pair of levers.

Honda President Sees Limited Role for Electric Cars

onda’s display at the 2011 Tokyo Auto Show is full of electric car concepts. Earlier this week, international journalists were given the opportunity to drive its impressive Fit EV pure battery electric car. So, when given the opportunity to ask a single question at yesterday’s press conference with Honda President Takanobu Ito at the Tokyo show, I tried to determine if the company’s man at the top has a vision for electric cars.

I’ll let Mr. Ito speak for himself in this unedited transcript of my question and his answer.
In your earlier comments, you identified the need for Honda to be ahead of your competitors on technology, especially hybrid and electric. Nissan is projecting to have 1.5 million cumulative sales of electric cars by 2015. What do you think of this forecast, and Honda’s ability to compete with pure electric vehicles?

First of all, just because Nissan is saying it’s going to sell some 1.5 million pure EVs, Honda is not going to say that [we are] as well. Instead, our way of thinking is, for us to contribute to sustainable society, we have to think about total sales of Honda vehicles, and thereby through our products, contribute to society.

With this in mind, compared to the year 2000, we need to reduce our CO2 emissions by 2020 by 30 percent. Pure battery EVs, of course, would be one means of trying to reduce CO2. I think there is no mistake about that.

I think the way people use cars is not the same across the board in all countries, so I cannot generalize. If you think about the concept EVs introduced by Honda at this Tokyo Motor Show, you see that electric cars are important. I will not deny that. But when you consider the performance of batteries, the charging times, plus the cost of batteries, I think pure EVs would be best for compact, very small cars.

I feel confident in saying that they could be a fit for very small vehicles. That is why last year we launched the motorcycle EV. We think we should expand on this and for mini-vehicles, an even smaller size category—the commuter car we introduced at the Tokyo Motor Show, which would be well suited for a pure EV.

Will this be acceptable in the United States? This is a question. Therefore, we are thinking of the Fit EV for the United States. But for Japan, Europe, and other parts of Asia—especially the urban areas, we think the smaller category would be an option that could be considered, if it could be easily charged and has good maneuverability. In this category, pure EVs would be appropriate.

So, we’ll start with the very small cars for the pure battery EVs. But when you think about other segments—compact cars and large vehicles—in order to contribute to sustainable society, fuel economy and reduction of CO2, I believe hybrids would be the best.

When I say hybrids, there are different types of hybrids. Honda has to think about what would be best for each of the categories. For example, we have strength in the one-motor system—a very simple IMA (Integrated Motor Assist). This is one thing that we feel is fit for this purpose. We think we can increase the number of sales, and we are preparing the next version of the IMA, trying to improve the performance.

For vehicles in the United States, say the Accord class, we have to secure sufficient motor performance. We have to further work on this to generate enough power during the driving. For this, we have to have a separate dedicated system for the Accord class and above.

If you’re talking about high-end expensive vehicles, fuel economy is not enough. It also has to be fun to drive. For that we have the SH-AWD [Honda’s new hybrid system primarily dedicated to enhancing driving dynamics]. For each class of car, there are different types of hybrids. We believe we already have the technology in our hands, and for the next 10 to 20 years, I think in order to reduce CO2, we would have to use these different technologies, of which pure battery cars are one. But proportion-wise, I think hybrids will be the largest.

What Gets His Motor Going
In the final question of the session, an American journalist followed up on the idea of Honda adding “more fun” to its vehicles—a notion that was frequently discussed in presentations to journalists in the past few days in Tokyo. The journalist mentioned Honda’s electric sports car concept on display.

“I would love to have an electric sports car, but I live in an apartment complex, so I’d have to run an extension cord across my parking lot in order to recharge it,” he said. “[Honda] used to have affordable sports coupes that were iconic around the world, the CRX, the Integra, Prelude, those cars that every man could afford that actually ran on gas. Is a car like that on the table, or does every future sports car need to have some sort of advanced powertrain. It seems like a gas powertrain might be more affordable to the masses.”

Mr. Ito broke into a smile and, for the first time in the one-hour conference, delivered his response in English—a single line: “I completely agree with you.”

Ici : http://www.lexpress.fr/actualites/1/economie/probleme-d-airbag-honda-rappelle-plus-de-900-000-vehicules-dans-le-monde_1057499.html
Citer
TOKYO - Le constructeur d'automobiles japonais Honda a annoncé vendredi qu'il rappelait plus de 900.000 véhicules dans le monde, essentiellement aux Etats-Unis, pour des problèmes d'airbags et que ce chiffre devrait augmenter à cause de rappels ailleurs dans le monde.
Les voitures concernées comprennent les modèles à succès Accord et Civic, populaires en Amérique du Nord.

Dans le pire des cas, la bouteille contenant le gaz servant à gonfler l'airbag peut exploser en cas d'accident et des morceaux de ce contenant peuvent s'éparpiller dans l'habitacle.

Honda a précisé que 304.035 unités de dix modèles fabriqués en 2001 et 2002 étaient rappelées dans le monde entier, dont 272.779 pour les seuls Etats-Unis et Canada.

Le constructeur remplacera la bouteille de gaz potentiellement défectueuse.

Il a ajouté que cette initiative complétait un rappel précédent de 950.000 unités pour un motif similaire sur des modèles fabriqués entre 2008 et 2010.

A cela s'ajoute un deuxième problème d'airbags, sur des véhicules dont le coussins de sécurité a vendu par Honda et a été installé par des garagistes sur des véhicules.

Les concessionnaires ou garagistes ont ainsi placé 640 de ces coussins de sécurité présentant un danger mais Honda ne sachant où ils se trouvent, va demander à inspecter 603.421 véhicules potentiellement concernés aux Etats-Unis.

"Cela représente 876.000 véhicules rien qu'aux Etats-Unis", plus 31.000 environ ailleurs dans le monde, et "il y aura sans doute d'autres rappels ailleurs dans le monde", a expliqué à l'AFP un porte-parole de Honda.

First Drive: Honda Accord Plug-In Hybrid Mule

Honda’s reputation as an innovator and technology leader wasn’t earned with the first hybrid brought to the U.S. market or its stubborn commitment to a hydrogen-powered prototype. Honda built its brand on the fundamentals of its most accessible and popular vehicles. Americans admired the simplest solutions to the most complex problems; they respected diligent engineering that set a standard of continuous improvement; and they believed in the company that was consistently one step ahead of the competition.

The company that once sold an affordable compact so clean it met emissions standards without a catalytic converter is hell bent on owning the hybrid market -- small as it may be, Prius be damned, and cost no object. So next year, Honda will add to its crowded stable of hybrids -- CR-Z, Civic, and Insight -- with a mid-size plug-in hybrid.

Not your typical Honda hybridHonda’s plug-in hybrid powertrain is far more sophisticated than the simple Integrated Motor Assist system found in Honda’s existing hybrids. It is also significantly different than the configurations used by the Toyota Prius and the Chevrolet Volt. No matter whether the Honda plug-in is relying on energy from its 6-kWh lithium-ion battery or its fuel tank, the wheels are primarily powered by a 161-hp electric motor. A second electric motor functions as a generator to convert power from a 2.0-liter four-cylinder into electricity for range far beyond the battery’s 10 to 15 miles. If the driver calls for quick acceleration or exceeds 62 mph, the gas engine will also kick on before the battery’s charge is exhausted. Recharging takes about one and a half hours with a 240-volt connection.

The Honda’s unusual trick (all good hybrids have at least one) is that the gas engine can be mated to the front wheels through a fixed gear ratio. While single-speed transmissions are common in electric vehicles, gas engines require multi-speed gearboxes to match the narrow rpm band where the engine is most efficient with the wide range of road speeds. Both the Prius and the Volt use continuously variable transmissions to blend electric and gas power on its way to the wheels. Honda’s single gear ratio has been optimized for low-load highway cruising, such that the gas engine never engages the wheels below 40 mph. An electronically controlled clutch engages the engine when the computer decides to send power directly from the gas engine to the wheels.

A test drive shorter than its electric rangeOver an extremely short, city-like loop, we sampled the hybrid powertrain packaged in the chassis of the current Honda Accord. The electric motor is plenty powerful to move at a normal pace without calling on the gas engine. Stomp on the throttle, though, and there’s a slight lag in power delivery and a CVT-like audible awakening as the engine spins up to high rpm and parks itself there. The Honda mule drove with less moaning than a Prius but less engine isolation than the Volt. Maximum acceleration is adequate but not quick.

We were never able to discern if the engine was driving the front wheels, although that doesn’t necessarily mean the system is seamless. It’s possible that the computer simply never saw fit to engage the clutch during our limited test drive. Brakes are easily modulated by hybrid standards.

Honda has committed to production for 2012, but it hasn’t let on if the powertrain will appear in the next Accord or an exclusive hybrid model. If Honda delivers on its claimed electric range of 10 to 15 miles, the mid-size plug-in hybrid will be aimed squarely at Toyota’s forthcoming Prius plug-in, a car that will certainly benefit from instant recognition as a hybrid.

The mysteries that remainIt’s clear that Honda is hoping the more sophisticated powertrain will be a feather in its cap and a step toward reclaiming its reputation as a technology leader. For that to happen, though, buyers will have to respond to this hybrid more strongly than they have to any of Honda’s previous gas/electric cars. While the plug-in hybrid features some genuine innovations, its chance of success depends just as much on unknowns like styling, pricing, and fuel economy
