KEY BENEFITS

• Reuses hydraulic system

technology while incrementally

building on the development of

advanced electronic systems, such

as electronic stability programs

(ESP), traction control, and brake

assist

• Uses software updates to simplify

the calibration process by

adjusting brake response and

pedal feel

• Improves connectivity with other

emerging systems, such as

adaptive cruise control

• Removes the large vacuum servo to

allow flexible installation

• Features an anti-lock braking

system (ABS) without feedback

from the pedal

OVERVIEW

Electrohydraulic braking (EHB) systems are

designed to allow electronic control of vehicle

braking while retaining a reduced hydraulic

system. The hydraulic system functions as a

reserve in the event of a failure in the electronic

control.

The EHB control unit receives inputs from sensors

connected to the brake pedal. In normal operation,

a backup valve is closed and the controller

activates the brakes of the wheel through an

electric motor driven hydraulic pump. When the

controller goes into a fail-safe mode, the backup

valve is opened, which allows the brakes to be

controlled through a conventional hydraulic

circuit.
