To allow energy recuperation for Hybrid Electric Vehicles (HEV) and Electric Vehicles (EV) there are further developments on braking systems necessary. Especially effects of non-constant motor characteristics like the dependency on rotational speed, consequences of a completely charged battery due to the availability or influences on the vehicle stability have to be determined. Since the first generation of regenerative braking systems is based on the standard Electronic Stability Control (ESC) the electric and hydraulic brake torque generation is superimposed. This has the advantage to be a simple and affordable solution for electrical machines up to 20kW. The function realization for the Peugeot 3008 Hybrid4 is made by using an ESP w/ RBC system from Bosch which allows a good level of recuperation during braking phases and engine drag. This so far unused potential decreases the vehicles fuel consumption significantly. The next generation will be a cooperative braking system in order to reach higher recuperation levels and avoid deceleration inconsistencies by means of automated torque blending, in particular with regard to powerful electrical machines. To fulfill future requirements, the braking architecture has to be extended with hydraulic or electric boost for assistance purposes and pedal decoupling. The choice of a specific solution implies considerations about drive train performances and architectures, cost / CO2 ratio, Integrated Combustion Engine (ICE) - EV - HEV mix, vehicle integration, performances, as well as safety issues. For PSA cars HEV of the first generation, the use of an ESP based solution with enhanced software and PTS is justified by the medium power of electric engine (20kW), the good recuperation efficiency measured in the NEDC cycle and the affordable cost of the system.
