Method and apparatus for dynamically controlling pressure within a vehicle brake system |
摘要 |
A method for controlling a vehicle wheel brake that includes applying a pulse width modulated voltage to an isolation valve located between a master brake cylinder and the wheel brake to develop a differential pressure across the isolation valve that is applied to the wheel brake. The differential pressure is a function of the duty cycle of the applied voltage. Because the operation of the isolation valve allows a flow of fluid through the valve, changes in the master cylinder pressure are passed through the isolation valve to the wheel brake.
