Abstract
A vehicle control device configured to control a vehicle configured to rotate each of four or more drive wheels by each of different motors, includes a motor control unit configured to control torques that are generated by the motors, and when oversteer has occurred during turning of the vehicle, the motor control unit performs a control upon oversteer, and when understeer has occurred during turning of the vehicle, the motor control unit performs a control upon understeer.
Claims25
A vehicle control device configured to control a vehicle configured to rotate each of four or more drive wheels by each of different motors, the vehicle control device comprising:
- a motor control unit configured to control torques that are generated by the motors,
- wherein when oversteer has occurred during turning of the vehicle, the motor control unit performs a control upon oversteer of causing the motor configured to rotate a front wheel on an outer side with respect to the turning to generate braking torque, increasing drive torque of the motor configured to rotate a rear wheel on an inner side with respect to the turning, and decreasing drive torque of the motor configured to rotate a rear wheel on an outer side with respect to the turning.
A vehicle control device configured to control a vehicle configured to rotate each of four or more drive wheels by each of different motors, the vehicle control device comprising:
- a motor control unit configured to control torques that are generated by the motors,
- wherein when understeer has occurred during turning of the vehicle, the motor control unit performs a control upon understeer of causing the motor configured to rotate a rear wheel on an inner side with respect to the turning to generate braking torque, increasing drive torque of the motor configured to rotate a front wheel on an outer side with respect to the turning, and decreasing drive torque of the motor configured to rotate a front wheel on an inner side with respect to the turning.
A control method of controlling a vehicle configured to rotate each of four or more drive wheels by each of different motors, the control method comprising:
- when oversteer has occurred during turning of the vehicle, causing the motor configured to rotate a front wheel on an outer side with respect to the turning to generate braking torque, increasing drive torque of the motor configured to rotate a rear wheel on an inner side with respect to the turning, and decreasing drive torque of the motor configured to rotate a rear wheel on an outer side with respect to the turning.
A control method of controlling a vehicle configured to rotate each of four or more drive wheels by each of different motors, the control method comprising:
- when understeer has occurred during turning of the vehicle, causing the motor configured to rotate a rear wheel on an inner side with respect to the turning to generate braking torque, increasing drive torque of the motor configured to rotate a front wheel on an outer side with respect to the turning, and decreasing drive torque of the motor configured to rotate a front wheel on an inner side with respect to the turning.
