PROBLEM TO BE SOLVED: To prevent execution of useless torque distribution by detecting the longitudinal acceleration of a vehicle, and determining racing when engine torque above a designated value is detected in the case where the longitudinal acceleration is near zero or a decrease slope. SOLUTION: During traveling of a vehicle, in a racing determining means 45 of an electronic control unit 29, it is discriminated whether the change amount of rotating speed of an engine detected from the rotating speed NE of the engine is a decreasing trend or an increasing trend. If the decreasing trend is determined, a timer is started, then the rotating speed change amount of the engine is compared with a designated reference value, and as a result, if the decrease is very gentle, it is discriminated whether the longitudinal acceleration G02 of a vehicle is in the range of 0 from the designated reference value or not. Subsequently, it is whether the torque TE exceeds the designated reference value or not, and if exceeds, racing is determined to stop the output of torque distribution ration TOBJ to a target current value operating means 44. |
