PROBLEM TO BE SOLVED: To reduce car speed and a turning radius, and facilitate handling of a vehicle by reducing driving force of a running driving source according to increase of a steerage angle, when the vehicle is turned with car speed of a threshold and less. SOLUTION: In and electronic controlling unit U, output signals such as an acceleration pedal control input detecting means S1 , a steering angle detecting means S2 , a shift position detecting means S3 , and a car speed detecting means S4 , are inputted. Car speed V is compared with a prescribed threshold V0 , a torque coefficient K is held to K=1 in the range where a steering angle S is from 0 to a first threshold S0 at the time of V<V0 , the torque coefficient K is reduced from K=1 to K=K0 in a range from the first threshold S0 to a second threshold S1 , and it is held to K=K0 in a range which exceeds the second threshold S1 . When the car speed V is the threshold V0 corresponding to the upper limit of creep running speed, a torque foundation value Ta is multiplied by the torque coefficient K, and a torque command value T is reduced, and thereby, car speed of creep running is reduced. |
