Abstract

A vehicle includes a drive motor and a motor controller. The drive motor is configured to transfer torque to a wheel. The motor controller is configured to perform torque variation control during a predetermined period, in which, in response to a predetermined trigger for performing a pseudo shift change, torque of the drive motor is decreased by a set variation amount and is then increased.

Claims (12)

1. A vehicle comprising:

a drive motor configured to transfer torque to a wheel;

a motor controller configured to perform torque variation control during a predetermined period, in which, in response to a predetermined trigger for performing a pseudo shift change, torque of the drive motor is decreased by a set variation amount and is then increased; and

a temperature detector configured to detect a temperature of an onboard power electronics device,

wherein, if the temperature is higher than or equal to a first threshold, the motor controller performs the torque variation control during a period longer than the predetermined period.

2. The vehicle according to claim 1 , wherein the predetermined trigger is provided by one or more of a vehicle velocity, an accelerator opening, an accelerator depressing speed, and a brake depression amount.

3. The vehicle according to claim 2 , wherein the predetermined trigger is satisfaction of any one of multiple conditions, and the set variation amount is associated with each of the multiple conditions.

4. The vehicle according to claim 3 , wherein, if the temperature is higher than or equal to a second threshold that is higher than the first threshold, the motor controller does not perform the torque variation control even if the predetermined trigger is present.

5. The vehicle according to claim 2 , wherein, if the temperature is higher than or equal to a second threshold that is higher than the first threshold, the motor controller does not perform the torque variation control even if the predetermined trigger is present.

6. The vehicle according to claim 1 , wherein the predetermined trigger is satisfaction of any one of multiple conditions, and the set variation amount is associated with each of the multiple conditions.

7. The vehicle according to claim 6 , wherein, if the temperature is higher than or equal to a second threshold that is higher than the first threshold, the motor controller does not perform the torque variation control even if the predetermined trigger is present.

8. The vehicle according to claim 1 , wherein, if the temperature is higher than or equal to a second threshold that is higher than the first threshold, the motor controller does not perform the torque variation control even if the predetermined trigger is present.
