ABSTRACT:
A road surface friction coefficient μ is calculated based on a detected lateral acceleration and a front-rear acceleration, and a roll angle is calculated using a roll rate. Further, a maximum engine torque value that can be applied to a drive wheel without causing slipping thereof is calculated based on the road surface friction coefficient μ and a gear ratio. A torque transmission rate that indicates a reduction rate for engine output is set so as to reduce in accordance with a roll angle, and a target engine torque value is calculated by correcting the maximum engine torque value using the torque transmission rate. Accordingly, adjustment is executed such that the engine output is made smaller as the roll angle increases. Thus, abrupt changes in vehicle behavior are not caused by sudden starting of control, and it is possible to inhibit drive feeling from deteriorating.
