PROBLEM TO BE SOLVED: To ensure stabilization of a vehicle behavior when shifting from yaw moment control to traction control.SOLUTION: A drive torque controller A of a vehicle comprises: a driving system capable of making driving torque transmitted to left and right drive wheels 5L, 5R different; a vehicle control module 1 for controlling a vehicle behavior by making the driving torque to the left and right drive wheels 5L, 5R different; and a motor controller 2 for starting control of reducing the driving torque to the drive wheels so that an actual slip value is converged to a TCS control target value when slip occurs in one of the left and right drive wheels 5L, 5R and the actual slip value is determined to be equal to or greater than a TCS (traction control of suppressing drive wheel slip) operation threshold value. In the driving torque controller A of the vehicle, when slip occurs during yaw moment control by left and right driving torque difference, the motor controller 2 sets the TCS operation threshold value and the TCS control target value to values smaller than a value when the left and right driving torque difference is zero.SELECTED DRAWING: Figure 1 |
