ABSTRACT:
An anti-skid control device for braking a vehicle safely and quickly comprises a wheel speed sensor, a computer and an actuator for controlling brake fluid pressure in a wheel cylinder. The computer calculates, based on the wheel speed detected by the sensor, a wheel slip ratio relative to a road surface, a wheel speed acceleration and a gradient of the wheel speed acceleration, and controls the actuator so that it increases, decreases or holds the brake fluid pressure according to the data calculated. The brake fluid pressure is decreased to avoid locking of the wheel when the slip ratio exceeds a predetermined value, the wheel speed acceleration is below a predetermined value and the gradient of the wheel speed acceleration becomes lower than the predetermined level. In this manner, the brake fluid pressure is not decreased unnecessarily, and a desirable anti-skid control is achieved for braking the vehicle quickly and safely.
