ABSTRACT:
A traction control device for a vehicle decreases the driving torque for a driving wheel connected to a power source through an automatic transmission in response to the detection of an excessively slipping tendency of the driving wheel at the time of acceleration of the vehicle. In the traction control device, the shifting motion of the automatic transmission is predicted by a shifting predicting means based on operational parameters of the power source and a shifting characteristic of the automatic transmission. The operational parameters of the power source are assumed by an foreseeing means based on values before shifting of the operational parameters of the power source and operational parameters of the vehicle as well as gear shift positions detected before and after shifting by a gear shift position detecting means. An actuator for changing the driving torque for the driving wheel is operated by a driving torque control section for determining a control quantity of driving torque based on detection values before shifting and assumed values after shifting of the operational parameters of the power source. As a result, the driving wheel speed is stabilized immediately at the completion of the shifting operation of the automatic transmission.
