ZF supplies new brake system to VW for its EVs
Volkswagen has asked ZF to deliver a new braking system for all EV models based on the electric MEB platform. Until now, the ID.3 and ID.4 electric cars on the platform are already in production. The system also manages the important recovery of braking energy.
The German supplier is mostly known for its gear systems, but it’s developing many other important car parts. ZF says that its new braking systems to only very good in recuperation but it is also supposed to meet “high comfort requirements and safety standards”. ZF claims that it should be easier to integrate into a vehicle’s electronics architecture thanks to an optimized software interface.
The software connection is important because the braking system has to communicate with other control units of the assistance systems to perform driving assistance functions such as automatic emergency braking.
Safety and comfort
Here, the safety criteria of the European road safety association EuroNCAP have been tightened. “New test protocols for functions such as automatic emergency braking, for example, require a stronger boost to provide braking force even faster and more dynamically,” says the supplier.
ZF has gone one step further with the brake control system’s software: “Previously necessary mechanical components” have been replaced by software. Technically, ZF’s brake control is based on a combination of an electronic brake booster (EBB) and the electronic stability control (ESC). The combination is intended to cover a wide range of vehicles, from small cars to SUVs and light commercial vehicles.
“We meet the trend toward electromobility with our entire range of technological solutions – not just in driveline technology,” says ZF CEO Wolf-Henning Scheider on the subject.
“This supply order from Volkswagen emphasizes how our competencies for braking systems as well as for networked systems contribute to increasing the range of our customers’ electric vehicles. To this end, our systems help to meet high comfort and safety requirements.”
