<P>PROBLEM TO BE SOLVED: To allow pressing control in a state where a vehicle is kept stopped and extend a range where the pressing control is allowed in a system where the pressing control for adding torque to a reduction gear mechanism in an MG (motor generator) during the vehicle stop is executed. <P>SOLUTION: A pressing torque (a target value) acted on a power transmission system (a vehicle wheel 14, a vehicle shaft 33, a propeller shaft 17, for example) by the pressing control, a slope torque acted on the power transmission system by road slope, and a brake torque capable of being added to the power transmission system by a brake device 34 are calculated, and the pressing control is allowed when a torque is set in a forward rotational direction of the power transmission system as a positive value and the brake torque, the slope torque, and the pressing torque satisfy the following both two conditions: ¾brake torque¾≥¾slope torque¾, ¾brake torque¾≥¾slope torque+pressing torque¾. <P>COPYRIGHT: (C)2012,JPO&INPIT |
