<p>A hydraulic actuator for a vehicle roll control system includes a fluid pressure transducer 28, housed in a valve block 16, the output characteristic of which is temperature dependent. In order to correct for this the temperature of the fluid is monitored. This is done by monitoring the duty ratio of the pulse width modulated driving signal to a control valve 22 in the block, which varies with temperature to produce a constant total current. <IMAGE></p> |
