摘要： In a slip control system for a vehicle a slip ratio of driving wheels of the vehicle is detected, and the slip of the driving wheels is controlled to converge on a predetermined target slip ratio when the slip ratio of the driving wheels exceeds a predetermined threshold slip ratio. When the vehicle is running a rough road, the threshold slip ratio is increased. The running condition of the vehicle is detected and increase of the threshold slip ratio is inhibited depending on the running condition of the vehicle.

摘要： A slip control system for a vehicle having a differential which distributes engine output to left and right driving wheels suppresses the engine output when the slip of at least one of the driving wheels exceeds a first threshold value. Slips of the left and right driving wheels are periodically detected, and a spin pattern of the driving wheels is periodically determined on the basis of the slips of the left and right driving wheels. Whether the vehicle is running on a split surface road, where the parts of the road surface in contact with the left and right driving wheels have different friction coefficients, is determined on the basis of the present spin pattern and the preceding spin pattern according to a predetermined split surface determining rule. When it is determined that the vehicle is running on a split surface road, the first threshold value is increased.

摘要： A braking force control system controls the brake fluid pressure applied to the wheel during braking when each of the wheels of the vehicle tends to lock so that the slip ratio of the wheel converges on a target slip ratio. The brake fluid pressure is once fixed at the beginning of the braking force control, and when the slip ratio falls below the target slip ratio by fixing the brake fluid pressure, the brake fluid pressure is increased at a first rate, and when the slip ratio does not increase to a predetermined slip ratio in a predetermined time after the slip ratio falls below the target slip ratio or when the rate of increase of the slip ratio after the slip ratio falls below the target slip ratio is lower than a predetermined rate, the brake fluid pressure is increased at a second rate which is higher than the first rate.

摘要： A first estimated vehicle speed is calculated on the basis of the highest of the speeds of the wheels and the deceleration of the vehicle. A second estimated vehicle speed which begins to reduce from a predetermined value at a predetermined rate independent from the change in the highest of the speeds of the wheels from the time the first estimated vehicle speed falls to the predetermined value is calculated. A slip ratio of each wheel is calculated on the basis of the first estimated vehicle speed when the first estimated vehicle speed is not lower than the predetermined value and on the basis of the second estimated vehicle speed when the first estimated vehicle speed is lower than the predetermined value. The braking force applied to each wheel is controlled so that the slip ratio of the wheel converges on a target slip ratio.

摘要： When a wheel slip value of the driven wheel relative to a surface of road becomes excessive during acceleration, torque to be applied to the driven wheels is controlled by the traction control so as to make the actual wheel slip value of the driven wheel become a predetermined target value. There is counted the duration of time during which the actual wheel slip value of the driven wheel becomes smaller than a predetermined threshold value set as a value smaller than the target value, and a control value for the traction control is corrected in accordance with the duration of time counted. This correction is implemented so as to increase the torque to be applied to the driven wheels larger as the duration of time counted becomes longer. The control value to be corrected includes the target value itself or a road surface friction coefficient .mu. as a parameter for setting the target value.
