What is Brake-by-Wire?
Technical function and components
A Brake-by-Wire system eliminates the direct mechanical or hydrostatic connection between the brake pedal and the actual brake actuator. The braking process is purely electronic:
- An electronic pedal detects the pedal movement as a control variable.
- This control variable is sent to our control electronics.
- The electronics precisely control the brake pressure by means of an electrically operated pressure control valve.
Parking and service brake
Safety thanks to power-off retracted parking brake
In addition to the actively controlled service brake, a reliable parking brake function is also available. Similar to pneumatic brakes, this brings the vehicle to a standstill in the passive state (power off).
The control unit operates in a fail-safe manner in accordance with the ISO 13949 Performance Level e (PL e) safety standard. This ensures that the power-off retracted parking brake is always available as a secure fallback level and that maximum functional safety is guaranteed.
FAQ - Brake-by-Wire Frequently Asked Questions
-
The mechanical connection is eliminated. An electronic brake pedal registers the braking request. An electrically operated pressure control valve then controls the brake pressure precisely and without delay.
Safety is achieved through redundant sensor technology and highly reliable components. Our control electronics are designed for use in critical braking applications.
We supply the complete core component: the control electronics with the specific application software and the hydraulic control block. The system can be flexibly adapted to your braking system.
Brake-by-Wire is ideal for special vehicles that have long distances between the pedal and the brake or that have many axles that are difficult to control conventionally.
