ZF’s newest brake system to be used in Volkswagen EVs

The latest in ZF brake control solutions will be the standard in Volkswagen’s ID.3 and ID.4 EVs, as well as future vehicles built on Volkswagen’s MEB modular e-drive system platform. 

ZF says its optimized software interface allows the new braking system to be integrated into the electronic architecture of VW vehicles while supporting driver assistance features such as automatic emergency braking. 

ZF brake control is based on a combination of the company’s electronic brake booster (EBB) and its latest-generation EBC470 electronic stability control (ESC). EBB and ESC cover a range of vehicles, including compact cars, SUVs and light commercial vehicles. Together, the two components are part of a brake architecture that combines a separate electric brake booster for enhanced brake actuation and electronic stability control to help stabilize the vehicle in challenging road conditions.

“The [EV] braking system utilizes intelligent integration in a number of ways,” said ZF Senior VP Manfred Meyer. “For example, we can eliminate the need for a mechanical locking mechanism in the drivetrain and keep the vehicle in park mode through software that controls this function within the ESC and redundantly in the Electronic Brake Booster unit. The brake system itself helps ensure that the car cannot move—this saves cost and results in less weight.” 

In the VW project, the system is part of a software network housed in the stability control unit. It meets safety standards set by the European road safety association EuroNCAP.
