Abstract
A vehicle having a drive motor is provided. The vehicle includes a controller that changes the inclination of a drive motor torque command based on a demand torque of a driver or a temperature of a drive motor. A motor controller then operates the drive motor to change the motor torque changes based on the inclination of the motor torque command.
Claims16
A vehicle having a drive motor, comprising:
- a controller configured to change an inclination of a drive motor torque command based on a demand torque of a driver or a temperature of a drive motor;
- and
- a motor controller configured to operate the drive motor to change the motor torque based on the inclination of the motor torque command,
- wherein the inclination of the motor torque command indicates an inclination of the torque command to gradually change the torque amount based on time until reaching from a current motor torque to a required motor torque.

A method of controlling a vehicle having a drive motor, comprising:
- computing, by a controller, a demand torque of a driver;
- measuring, by the controller, a temperature of the drive motor;
- changing, by the controller, the inclination of a drive motor torque command based on a size of the demand torque of the driver or the temperature of the drive motor;
- and
- operating, by the controller, the drive motor to change the motor torque based on the changed inclination of the motor torque command,
- wherein the inclination of the motor torque command indicates an inclination of the torque command to gradually change the torque amount based on time until reaching from a current motor torque to a required motor torque.
