SLIP CONTROL SYSTEM FOR A 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.
