A vehicle moves unintentionally in a downwardly-reverse direction with a forward creep torque being outputted as shown by a time variation of vehicle speed VSP, and a braking is applied at timing t3 in order to prevent this downward movement. In this case, the downward movement in the reverse direction is detected by sensing a relation of VSP<-V1 at timing t1, and then this state continues for a duration set corresponding to a timer value NTM1. At timing t2, a creeping-cut is prohibited by setting a creeping-cut-prohibition flag NFLAG at "1". At timing t3, the braking is started in order to prevent the reverse-directional downward movement. Thereby, at timing t5, the vehicle speed VSP becomes near 0. In response thereto, a conventional creeping-cut permitting flag FLAG is set at 1. However, the creep toque continues to be outputted also after t5 without the creeping-cut, so that a torque reduction accompanied with strangeness feeling can be prevented from occurring due to an execution of the creeping-cut at t5.
