<p>In a hydraulic system for traction control, a pump (12) is adapted to withdraw fluid from a reservoir (6) through a master cylinder assembly (1) under the control of a solenoid-controlled valve (11) responsive to signals from an electronic control module (30), and a pressure-sensitive valve (20). The system is also provided with a solenoid-controlled flow control valve (7) also responsive to signals from an electronic control module (30), a switch (33) is responsive to movement of the throttle (34) of the engine of a vehicle, and from which signals are transmitted to the control module (30). Thus, when the signal from the switch (33) changes as the foot is released from the throttle pedal, the control module (30) recognises the change in signal and re-sets the modulator means, for example the solenoid-operated flow control valve (7). <IMAGE></p> |
