Braking Technology - The Electronic Wedge Brake (EWB)

Gentle braking for active safety

The electronic wedge brake utilizes a completely new braking technology based on a principle that is as simple as it is effective. Manufacturers and end customers alike will benefit from its advantages.

Technology

Technology

The electronic wedge brake uses a new technology that far exceeds the technical performance of today’s hydraulic systems. At the same time, it helps car manufacturers to accelerate and simplify their development and production.

Architecture

The electronic wedge brake is a mechatronic solution that works without any hydraulics. Its architecture is simpler and more convenient than traditional braking systems and also offers new freedom to manufacturers

Principles

With an electronic wedge braking system, each wheel has its own intelligent wheel-brake module. The brake is driven by two brushless motors. Commutation and current control are performed using commercial motor drives with an incremental encoder on each motor shaft.

Functionality

Functionality

The electronic wedge brake automatically multiplies the braking force used. The kinetic energy of the vehicle itself is thereby actually used to help brake

Active Safety

Drivers benefit especially from additional active safety. Compared to hydraulic systems, the brake responds more quickly and can be applied with a finer touch, and stopping-distance figures are optimized.
