PROBLEM TO BE SOLVED: To perform regenerative operation of an electric motor so that acceleration appropriate to a slope of a road surface may be generated in a vehicle, while lessening an impact of a disturbance factor, when the electric vehicle runs on a descent. SOLUTION: The electric vehicle includes a means 25 to determine target acceleration of the vehicle 1 according to the slope of the road surface, wherein operating states of an accelerator and a brake of the vehicle 1 are in an off-state at running of the vehicle 1 on the descent, a means 26 to determine a correction amountΔTrd of regenerative torque to approximate actual acceleration of the vehicle 1 to the target acceleration, a means 21 to determine basic target torque Trs of the electric motor 2 according to the operation state of the accelerator, wherein the regenerative torque is output when the operation state of the accelerator is in the off-state, and a means 27 to determine target torque Trc correcting the basic target torque Trs by at least the correction amountΔTrd. Output torque of the electric motor 2 is controlled aiming at the target torque Trc. COPYRIGHT: (C)2009,JPO&INPIT |
