Abstract
An anti-skid control system for an automotive vehicle is provided with an actuator which is disposed in a hydraulic circuit between a hydraulic pressure generator and a wheel brake cylinder. The actuator is operated by an electronic controller so as to control a hydraulic braking pressure supplied to the wheel brake cylinder in response to at least an output of a wheel speed sensor which detects a rotational speed of a road wheel. In the controller, a desired hydraulic pressure is set, and the actuator is operated to control the hydraulic braking pressure to the desired hydraulic pressure. Where the actuator comprises a proportional pressure control solenoid valve connected to the controller which is provided with a resistor for detecting a current fed to the solenoid valve, the desired hydraulic pressure is set in response to the current.
