Abstract:
An anti-skid control system for an automotive vehicle, comprising:a plurality of actuators each actuator associated with one of four road wheels located respectively at front-left, front-right, rear-left and rear-right portions of the vehicle, for adjusting braking forces applied to the four road wheels independently of each other;sensors for detecting a wheel speed of the four road wheels to generate wheel-speed indicative signals; anda controller for controlling the actuators in response to the wheel-speed indicative signals,wherein the controller controls the actuators associated with the front wheels of the four road wheels independently of each other based on respective values of the wheel-speed indicative signals of the front wheels,wherein the controller controls the actuator associated with a controlled outer rear wheel of the four road wheels, which controlled outer rear wheel is subjected to a braking-force control, with reference to both a value of the wheel-speed indicative signal of the controlled outer rear wheel and a value of the wheel-speed indicative signal of a diagonal front wheel located on the vehicle diagonally to the controlled outer rear wheel, when the vehicle is in the cornering state with a high lateral acceleration during the braking-force control for the controlled outer rear wheel,wherein the controller controls the actuator associated with a controlled inner rear wheel of the four road wheels, which controlled inner rear wheel is subjected to a braking-force control, with reference to both a value of the wheel-speed indicative signal of the controlled inner rear wheel and a value of the wheel-speed indicative signal of an opposite rear wheel opposite to the controlled inner rear wheel, when the vehicle is in the cornering state with a high lateral acceleration during the braking-force control for said controlled inner rear wheel.
