Slip control device for vehicle

Abstract

Abstract PURPOSE:To prevent the speed variation in the right and left driving wheels, when a slip condition is detected, by selectively outputting either control signal for regulating independently respective braking forces of the right and left driving wheels or control signal for regulating dependently respective braking forces, in response to the difference in the wheel speeds of the right and left driving wheels. CONSTITUTION:A wheel speed detecting means 1 for detecting the wheel speeds of the right and left driving wheels respectively, and an acceleration slip detecting means 2 for detecting the acceleration slip condition of at least one side of the right and left driving wheels at the time of start acceleration on the basis of the output signal of the former means are provided. Further, a wheel speed difference detecting means 3 for detecting the difference in the wheel speeds of the right and left driving wheels on the basis of the output signal of the wheel speed detecting means 1 is provided. And when acceleration slip is detected, a control signal is selectively output by a braking force regulating means 4 to a braking means 5 so that, if the difference in the wheel speeds of the right and left driving wheels is larger, the increase or decrease in the brake pressure is independently carried out in the right and left wheels; and if the difference in the wheel speeds is smaller, the increase or decrease in the brake pressure is dependently carried out in the right and left wheels.
