Abstract:
According to the present invention, a control unit controls torque, in a normal range, in accordance with an ordinary map which indicates the correspondence among the torque, the motor rotational speed, and an accelerator operation amount in the normal range. The control unit controls torque, in a deterioration range, so as to be suppressed more than that in the normal range in accordance with a suppression map which indicates the correspondence among the torque, the motor rotational speed, and an accelerator operation amount in the deterioration range. The control unit switches, when it is determined that the deterioration range has been reached, from the torque control based on the ordinary map to the torque control based on the suppression map through passage of a deterioration-time switching time period required for switching, which is to be performed when deterioration range has been reached, the torque control after a deterioration determination time at which it is determined that the deterioration range has been reached.
