An electrohydraulic braking (EHB) system comprising a brake fluid reservoir, a pump connected to the reservoir for providing a supply of pressurized brake fluid, an accumulator connected to the pump for storing pressurized brake fluid, control valves coupled to the accumulator and reservoir for selectively supplying pressurized brake fluid from the accumulator to a brake actuator for application of a vehicles brake and discharging brake fluid from the brake actuator back to the reservoir for release of the brake, and an electronic control unit (ECU) which evaluates the driver's braking demands and controls the valves and pump accordingly, and wherein, for providing an indication of brake fluid consumption, a comparison is made during a braking operation of the volume of brake fluid which is taken from the accumulator with the volume of brake fluid which is supplied to the brake actuator. |
