ABSTRACT:
An electric vehicle includes a device which determines, on the basis of the gradient of a road surface, a target acceleration of the vehicle in the case where the operational states of an accelerator (gas) pedal and a brake pedal of the vehicle are an OFF state when the vehicle is traveling on a down-slope road, a device which determines the correction amount of a regenerative torque for bringing the actual acceleration of the vehicle close to the target acceleration, a device which determines a basic target torque of an electric motor, which becomes a regenerative torque when the operational state of the accelerator (gas) pedal is the OFF state, on the basis of the operational state of the accelerator (gas) pedal, and a device which determines a target torque by correcting the basic target torque on the basis of at least the aforesaid correction amount. The output torque of the electric motor is controlled to the determined target torque. Thus, when the electric vehicle travels on the down-slope road, the regenerative operation of the electric motor is accomplished such that an acceleration suited to the gradient of the road surface can be generated in the vehicle while minimizing the influences of disturbance factors.
