PSA Peugeot Citroën and Robert Bosch GmbH have agreed to a strategic partnership for diesel hybrid technology. The recently signed agreement calls for Bosch to co-develop, industrialize and supply electric motors and power electronics for PSA Peugeot Citroën’s four-wheel-drive diesel hybrid powertrain.

Unveiled at the Paris Motor Show on the Peugeot Prologue and Citroën Hypnos concept cars (earlier post) , this diesel hybrid technology will equip Peugeot and Citroën vehicles starting in 2011.

As part of the agreement, Bosch will supply the rear electric motor, the front-mounted high voltage alternator and the power electronics that will control them. In addition, Bosch will deliver to PSA Peugeot Citroën specifications the interface between the electric and electronic components, the antilock braking system (ABS) and the electronic stability program (ESP) to enhance energy recovery.

PSA said that diesel hybrid technology is a key focus of its environmental strategy, and that developing and industrializing this technology is a major challenge for the carmaker. By choosing a core partner, PSA Peugeot Citroën said it is paving the way to rapid market introduction of hybrid diesel vehicles in Europe.

This stronger collaboration between the partners’ engineering and design teams will optimize the hybrid powertrain’s operation while speeding the acquisition of mutual expertise in this area, which is expected to expand rapidly in the next few years.

The carmaker said that it believes this is the right approach for bringing to market quickly and cost effectively technological innovations that can significantly lower CO2 emissions. PSA Peugeot Citroën also hopes that this agreement will strengthen the European hybrid technology industry.

For Bosch, the close cooperation with PSA Peugeot Citroen offers a promising opportunity to jointly develop an innovative, powerful and competitive hybrid system. Within the Bosch group, the expertise of roughly 370 associates is pooled in a hybrid project unit, whose purpose is to develop and market systems and components for hybrid and electrical vehicles.

At first sight, this approach represents one of the easiest and probably lowest cost hybidization of an exisitng Diesel (or gasoline) powered car.

It has the advantage of being able to operate as a normal Diesel (or gasoline) ICE vehicle with the integrated e-motor + battery + associated components being taken for a free ride, as and when required. It should improve city mileage if the extra weight can be kept to a minimum.

In normal hybrid mode, it should do as good and even better than the Prius New Generation. With an additional modular battery pack (or two) it could quickly become a PHEV-20, PHEV-40 or PHEV-60. Of course, the 50 KW integrated e-motor could be upgraded for heavier vehicles.

Interesting variable combination possiblities from another world class manufacturer.

Can it be made light enough to compete (fuel consumption wise) with other hybrids/PHEVs like the Volt, the future Toyota Prius PHEV and other PHEVs from Hyaundai, BYD etc? The small very efficient Peujeot Diesel will certainly contribute possitively.

Wouldn't be surprised to see Mercedes, BMW and WV/Audi, Renault etc use a similar approach in the near future.

Nice to see something a little different being commercialized - a diesel hybrid through the road, also allowing 4WD. I wonder what the anticipated cost and volume are, though.

That looks like a very small battery as presented in their concept car picture (much smaller than a Prius battery).

Perhaps they are anticipating the switch to high specific power lithium-ion?

HarveyD

clett:

Point well taken. It may be sufficient for a regular Hybrid similar to Toyota's Prius I & II or even the Prius III, but with a different approach.

Future PHEV versions would need additional batteries and possibly larger e-motor.

Nissan is also working on something very similar but more complex with larger battery packs.

Hybrids, upgradable to PHEVs, are very interesting for the next decade or until such times as battery packs performance can supply 300+ miles range for BEVs.

Would be interesting to know the weight distribution (front/rear).
For regen braking it would be better if it was on front wheels, driver may have some un-natural feel when braking if most of it is applied to the rear (Think of using emergency brake). It can affect stability when slippery, easier to go into skid.
On the other hand it should have excellent acceleration from standstill.

They also said the Hypnos diesel is equipped with stop-start system. Actually there is not much need for it in a hybrid capable of electric-only start. Assuming that most stops can be anticipated (stop lights, final destination, traffic jam etc), a driver can save much more fuel by turning off engine (with Engine Start/Stop button) well ahead of stop point, going into regen mode, and later starting with e-motor and then restarting engine.

Applying the regengine brake at the back will help keep the tail trim behind as per all standard automotive application, motorbike or powered trailer brakes if you are familiar with this effect, lock up is not an option on modern abs .
In single axle drives of course it would be on that axle.

They should used Michelin Wheel motors. I think that will be true revolution. Any car could be converted in to series hybride

mki:

Yeah for the wealthy...4 drive motors, 4 suspension motors, and a generator? The "conversion" would cost as much as any used car to be converted would be worth. It is cool though.

Even wheel motors on their own without that suspension and brake setup will probably be limited without breakthrough cost improvements for the vast majority of the global vehicle buying population. I'm sure will be _some_ great cars with wheel motors, perhaps like the Mitsubishi Evo electric, but if they're going to sell a lot of these things they need to drive the system cost down as much as possible, batteries will always be a large expense, so simple is probably best.

TIME FRAME OF 2011 IS TOO LONG. IT SHOULD BE ON ROAD BY 2009 . WHAT IS DELAYING ELECTRIC CARS SO MUCH. TO BEGIN WITH WE SHOULD HAVE SMALL ELECTRIC CARS OF 100 KMS RANGE IMMEDIATELY BASED ON LITHIUM BATTERIES.

Diesel engines can run dual fuel with natural gas, if most driving energy requirements can be replaced with renewable electricity and natural gas it will bankrupt OPEC and be good for emissions and air quality.

Biofuels should be used for stretching supplies of natural gas, digestion of waste and fast growing grasses can supply biogas and fertilizer product which can return nutrients to the soils.

Any land near an existing roadway can become a petrol station offering wind powered battery charging and biogas/bio diesel fill ups.

Gas can be used highly efficiently to generate electricity (60% in combined cycle) and makes use of existing infrastructure. Also small volumes of hydrogen( up to can be incorporated into the mix without needing to change infrastructure.
