ABSTRACT:
An anti-skid control device includes wheel brake cylinders, a hydraulic pressure generator, and hydraulic pressure control valves for controlling the hydraulic braking pressure in each wheel brake cylinder. The wheel speeds of the plurality of wheels are sensed by respective wheel speed sensors, and the vehicle speed is calculated on the basis of the wheel speeds. A right vehicle speed is calculated on the basis of the wheel speed of one of the wheels on the right hand side of the vehicle and a left vehicle speed is calculated on the basis of the wheel speed of one of the wheels on the left hand side of the vehicle. A vehicle speed differential between the right vehicle speed and the left vehicle speed is calculated. A vehicle lateral acceleration is then calculated from the vehicle speed differential and the vehicle speed. When the vehicle lateral acceleration exceeds a first predetermined value before an anti-skid control starts operating during depression of the brake pedal, an increase rate of the hydraulic braking pressure in an inside rear wheel is reduced.
