Creeping-cut control apparatus for electrically driven vehicle

Abstract

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 tin order to prevent this downward movement. In this case, the downward movement in the reverse direction is detected at timing t, and then this state continues for a duration set corresponding to a timer value NTM. At timing t, a creeping-cut is prohibited by setting a creeping-cut-prohibition flag NFLAG at '1'. At timing t, the braking is started in order to prevent the reverse-directional downward movement. Thereby, at timing t, 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 twithout the creeping-cut, so that a torque reduction accompanied with strangeness feeling can be prevented.
