摘要： A traction control system for a vehicle has a sub-throttle valve provided in an intake passage of the engine in series to a main throttle valve which is operatively connected to an accelerator pedal to open and close in response to operation of the accelerator pedal. An engine output controller controls opening of the sub-throttle valve to control the output of the engine so that the slip value of the driving wheels converges on a target slip value. The engine output controller once moves the sub-throttle valve to an initial opening when the slip value of the driving wheels exceeds the target slip value and then controls the opening of the sub-throttle valve to control the output of the engine so that the slip value of the driving wheels converges on a target slip value. The initial opening is set to be a fixed value when the opening of the main throttle valve is not larger than a predetermined opening and to be substantially equal to the opening of the main throttle valve when the opening of the main throttle valve is larger than the predetermined opening. The fixed value is not smaller than the predetermined opening of the main throttle valve.

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 contains a first control unit for implementing feedback control of torque applied to the driven wheels so as to allow an actual slip value of the driven wheel to reach a predetermined target value. There are set a first judgment value larger than the target value and a second judgment value smaller than the first judgment value. A second control unit is provided for temporarily reducing the torque applied to the driven wheel by a predetermined decrement, in place of the feedback control, when the actual slip value reaches the first judgment value or larger than the first judgment value. There is further provided a third control unit for gradually reducing the torque applied to the driven wheel, in place of the feedback control, when the actual slip value of the driven wheel does not reach the second judgment value or a value smaller than the second judgment value even if a predetermined period of time elapses after start of control by the second control unit.

摘要： The slip control is conducted so as to cause an amount of the slip of the driven wheel to become a target value by controlling the torque to be transmitted to the driven wheel. The target value is altered during the slip control on the basis of a requirement for road holding capabilities of the driven wheel against a road surface.

摘要： A slip control system for a motor vehicle controls slippage of driving wheels and includes, a sensor for detecting a slip ratio of each driving wheel, a device for detecting a reduction in speed of each wheel, and a traction control system for decreasing a slip of each driving wheel by controlling brake fluid pressure in each driving wheel so that the slip ratio of each driving wheel is at least equal to a predetermined desired slip ratio when the slip ratio of each driving wheel becomes equal to the desired slip ratio. The system further includes an antiskid brake system for controlling brake fluid pressure, based on the reduction speed of each wheel, so as to cancel a lock condition of the wheel. The antiskid brake system has a first control device for controlling the brake pressure fluid in a condition in which a traction control operation is not carried out by the traction control system, and a second control device for controlling the brake pressure fluid in a condition in which a traction control operation is carried out by the traction control system.

摘要： A slip control system is so adapted as to start the control of the braking force from a state in which the braking force is reduced when a magnitude of deceleration of the wheel becomes equal to or larger than a predetermined value or when a slip value of the wheel becomes a value in the direction in which the wheel is likely to be locked and as to start the control of the braking force from a state in which the braking force is sustained when the deviation obtained by subtracting the wheel speed from the vehicle speed becomes equal to or larger than a predetermined value. This arrangement satisfies requirements for both preventing the wheel from being locked and shortening the braking distance.
