Electric Powertrain’s Impact on Braking System

Excerpt

Electrification of the powertrain has considerable effects on the chassis systems, particularly on the brake system. Adaptations are necessary, for example, to enable energy recovery to be applied. This has consequences for the system software, the modulation hardware and the pedal feel. Furthermore, brake assist systems for zero-emission vehicles require electric vacuum pumps or other non-vacuum systems. In order to achieve further synergies in the chassis, suitable interfaces need to be created between the regenerative brake system, the steering, the suspension and the axles. In the following report, PSA and Bosch describe which solution has been implemented in the hybrid version of the Peugeot 3008 and which systems are to be expected in the future. …
