As ZF announces, the order for the braking system covers several million Volkswagen Group vehicles, initially including the ID.3 and ID.4 models. The system can do more than just braking: with an optimised software interface, it can be integrated and networked into the vehicles' electronics architecture more easily than before. The system also supports driver assistance functions such as automatic emergency braking. In addition, the solution replaces previously necessary mechanical components with software functions, which saves weight and costs.
Technically, ZF brake control is based on a combination of electronic brake booster (EBB) and electronic stability control (ESC). EBB and ESC cover a wide range of vehicles, from small cars to SUVs and light commercial vehicles. In combination, the two components are part of a brake architecture that combines an electric brake booster for enhanced brake actuation and electronic stability control.
In the current customer project, the system is part of a software network housed in the stability control unit. It meets the strict safety standards of the European road safety association EuroNCAP. 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.
In addition to these requirements, these brake systems also support the easy integration of a wide range of automated functions. The brake control system acts in conjunction with other chassis systems to provide precise vehicle control. For example, it eliminates the need for a mechanical parking lock in the drive. A software function ensures that the vehicle is held in parking mode by the electric parking brake. This function is controlled within the ESC and redundantly in the EBB unit.
