An electrical vehicle is provided with an accelerator pedal and an electrical motor (4) engaged with the drive wheels. A target vehicle drive force ( tFw ) is calculated on the basis of the vehicle speed and the depression amount of the accelerator pedal. The drive force of the motor (4) is controlled through an inverter (16) based on the target vehicle drive force ( tFw ). During deceleration, a regenerative braking effect is obtained by using the motor (4) as a generator on the basis of a negative value for the target vehicle drive force ( tFw ). It is possible to improve the power generation efficiency of the generator and to prevent unintended acceleration of the vehicle on a downward sloping road by increasing the power generation load of the generator as the amount of variation in the vehicle speed increases. |
