ABSTRACT:
In a hydraulic system for traction control, a pump is adapted to withdraw fluid from a reservoir through a master cylinder assembly under the control of a solenoid-controlled valve responsive to signals from an electronic control module, and a pressure-sensitive valve. The system is also provided with a solenoid-controlled flow control valve also responsive to signals from an electronic control module, a switch is responsive to movement of the throttle of the engine of a vehicle, and from which signals are transmitted to the control module. Thus, when the signal from the switch changes as the foot is released from the throttle pedal, the control module recognizes the change in signal and re-sets the modulator means, for example the solenoid-operated flow control valve.
