<P>PROBLEM TO BE SOLVED: To prevent an unreasonable torque reduction from being generated due to an execution of a creeping-cut when an electric vehicle is braked so as to prevent a backward movement in a creep torque output state. <P>SOLUTION: If a vehicle is in the forward creep torque output state and slides down in the backward direction indicated by a temporal change in a vehicle speed VSP and is braked so as to prevent the sliding down in the backward direction at t3, the sliding down in the backward direction is detected by the vehicle speed VSP<-V1 (t1). When the state is continued for preset time corresponding to a timer value NTM1 (t2), the creeping-cut is prohibited by a creeping-cut prohibition flag (NFLAG=1). Even if a conventional creeping-cut permission flag (FLAG) is set to 1 in response to the vehicle speed VSP of approximately 0 at t5 by initiating the braking for preventing the movement of the vehicle in the backward direction at t3, the corresponding creeping-cut is not implemented, and the creep torque is continuously output after t5. <P>COPYRIGHT: (C)2012,JPO&INPIT |
