摘要： A slip of the driven wheels is converged by causing the torque generated by the engine to be reduced and applying braking force when a slip of the driven wheel becomes large during accelerating. Control of the application of the braking force to the left-hand and right-hand driven wheels is made individually and separately from each other. When such an incident occurs as causing no normal control of decreasing the torque generated by the engine to be made, the contents of control of application of the braking force is changed so as to apply the same degrees of the braking force to both of the left-hand and right-hand driven wheels.

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 shift is implemented from the control for elevating the braking force to the control for retaining the braking force when deceleration of the wheel exceeds a first predetermined threshold value when the wheels are braked. The first predetermined threshold value is so set as to become smaller as an assumed road surface friction coefficient .mu. is smaller. The first threshold value is further altered to a larger value by altering the assumed road surface friction coefficient .mu. to a higher one when the period of time required from the start of the control for elevating the braking force to the start of the following control for retaining the braking force is equal to or shorter than a predetermined period of time.

摘要： Slip control is carried out so as to reduce torque applied to the driven wheels by reducing torque generated by the engine when a slip value against the driven wheels on pavement is larger than a predetermined value. A shift characteristic of the automatic transmission interposed between the engine and the driven wheels is set as a first shift characteristic which is a basic characteristic at the time of ordinary running where no slip control is carried out and as a second shift characteristic set so as to become at least unlikely to cause downshifting during slip control compared with said first shift characteristic. As the slip control terminates, a return of the first shift characteristic is prohibited when the torque generated by the engine is large (for example, when a degree of operation of an accelerator is not zero) or when downshifting is caused if based on the first shift characteristics.

The estimating device calculates, in a first predetermined time period immediately after the traction control is started, an acceleration of the driven wheel based on a speed difference of the driven wheel during a second predetermined time period and an acceleration of the driven wheel based on a speed difference of the driven wheel during a third predetermined time period after the first predetermined time period has passed. The estimating device then estimates the friction coefficient of the road surface by using the calculated acceleration of the driven wheel.
