Electronic Variable Brake Proportioning

ELECTRONIC VARIABLE BRAKE PROPORTIONING

Vehicles equipped with ABS use Electronic Variable Brake Proportioning (EVBP) to balance front-to-rear braking. The EVBP is used in place of a rear proportioning valve. The EVBP system uses the ABS system to control the slip of the rear wheels in partial braking range. The braking force of the rear wheels is controlled electronically by using the inlet and outlet valves located in the Integrated Control Unit (ICU).


EVBP activation is invisible to the customer since there is no pump motor noise or brake pedal feedback.
