Filed: 1987-10-16
Abstract: PURPOSE:To improve the advantages of high-speed running stability much more by providing a rear wheel slip detecting means in a control unit, and controlling a rear wheel steering angle in the direction of increasingly strengthening an under-steering tendency when a rear wheel slip occurs. CONSTITUTION:A rear wheel slip detecting unit detects the rotating speeds of each wheel based on wheel-speed signals inputted from each car-speed sensors 15L, 15R and 16L, 16R, and picks out the lowest rotating speed out of the rotating speeds of each wheel detected at a state where the brake is not applied. Then, the rotating speeds of rear two wheels are compared with the value obtained by multiplying the above lowest rotating speed by a constant, and when at least either of the rotating speeds of the rear two wheels is greater, it is judged that a rear wheel slip occurs. And at this time, the amount of steering of the rear wheels 13 in the direction of under-steering (in-phase steering gear change direction) is allowed to be increased much more than usual, thus an inward yaw-moment in a vehicle generated due to the rear wheel slip is eliminated, and a spin of the vehicle can be prevented.
