PURPOSE:To carry out output control in correspondence with a road surface condition by setting a stability factor of a car in accordance with an estimated road surface friction coefficient, and calculating target drive torque by way of computing cross acceleration of the car on the basis of this data and others. CONSTITUTION:A torque computing unit 76 to calculate target drive torque of an engine 11 inputs output signals of a throttle opening sensor 67, an idle switch 68, an acceleration opening sensor 77, rear wheel rotation sensors 80, 81, a steering angle sensor 84 and others. And the target drive torque at slip control in the case when the slip amount of a drive wheel becomes larger than a set amount and the target drive torque at turning control in the case when cross acceleration generated to a turning car are computed. At the turning control here, the cross acceleration is computed on the basis of a stability factor set in accordance qith an estimated road surface friction coefficient, an steering angle and car speed, and the target drive torque in accordance with this cross acceleration is calculated. |
