Bosch and PSA Peugeot Citroën presented two prototype vehicles that use the Optimal Energy Consumption and Recovery (OpEneR) system at the International Environmentally Responsible Car Show (RIVE) in Alès, France. OpEneR is a European research project designed to increase the range of future hybrid and electric vehicles by optimizing energy management.
Launched in 2011, OpEneR uses data from onboard sensors and telematics to optimize cooperation between a vehicle’s electric drivetrain and its regenerative braking system. Software algorithms merge data from a wide range of sources to provide guidance through dashboard displays, allowing drivers to adapt their route and driving style to achieve the best energy efficiency.
The two prototypes, built on a Peugeot 3008 platform, use several new drivetrain technologies, including:
- an electric powertrain based on two e-machines that deliver four-wheel drive.
- a new-generation stop/start system that enables freewheeling.
- Bosch’s ESP electronic stability program, which recovers energy when braking; and iBooster, which creates more vacuum-free brake pressure.
