摘要:
An electronic brake management system for controlling the application of fluid pressure to the brakes associated with wheels on a vehicle is disclosed. The system comprises a plurality of hydraulic valves for controlling the application of fluid to the brakes and a plurality of valve drivers for controlling the valves in accordance with respective electrical control signals for the plurality of valves. The system further includes a valve pulse width modulation controller for generating the respective electrical valve control signals applied to the valve drivers. The electrical valve control signals from the pulse width modulation controller are modulated to reduce the amount of electrical power supplied by the individual ones of the electrical signals once the valve associated with the one of the electrical signals has changed its opening to a desired position. The system further includes a brushless motor for driving a hydraulic pump for supplying fluid to the brakes in accordance with a pulse width modulated motor control signal from a motor signal modulation controller. The brushless motor provides a feedback signal to the motor signal modulation controller which is indicative of the position of the brushless motor rotor.
