Abstract
A method of controlling anti-jerk of a vehicle, includes determining a correction factor based on a wheel slip amount of the vehicle, determining a corrected model speed from a predetermined model speed for a motor of the vehicle based on the correction factor and a motor speed of the vehicle from which a vibration component is removed, determining a vibration component based on the motor speed and the corrected model speed and generating an anti-jerk torque based on the determined vibration component, and generating a final output torque of the motor based on a driver demand torque of the vehicle and the generated anti-jerk torque.
Claims16
A method of controlling anti-jerk of a vehicle, the method comprising:
- obtaining, by a controller, a motor speed of the vehicle by use of a sensor, wherein the motor speed includes a wheel slip component and a vibration component;
- determining, by the controller, a first motor speed which is obtained by subtracting the vibration component from the motor speed;
- determining, by the controller, a correction factor based on a wheel slip amount of the vehicle;
- determining, by the controller, a corrected model speed from a predetermined model speed for a motor of the vehicle based on the correction factor and the first motor speed, wherein the corrected model speed includes the wheel slip component;
- determining, by the controller, the vibration component based on the motor speed and the corrected model speed, and generating, by the controller, an anti-jerk torque based on the determined vibration component;
- and
- generating, by the controller, a final output torque of the motor based on a driver demand torque of the vehicle and the generated anti-jerk torque.
A method of controlling anti-jerk of a vehicle, the method comprising:
- determining, by a controller, a wheel slip amount of the vehicle;
- turning off, by the controller, an anti-jerk control function of the vehicle and turning on, by the controller, a wheel slip control function of the vehicle when the controller concludes that the wheel slip amount is greater than a predetermined first threshold value;
- and
- maintaining, by the controller, existing control of the vehicle when the controller concludes that the wheel slip amount is less than or equal to the predetermined first threshold value.
A system for controlling anti-jerk of a vehicle, the system comprising:
- a sensor unit;
- and
- a controller electrically connected to the sensor unit,
- wherein the controller is configured to:
- obtain a motor speed of the vehicle by use of a sensor, wherein the motor speed includes a wheel slip component and a vibration component,
- determine a first motor speed which is obtained by subtracting the vibration component from the motor speed,
- determine a wheel slip amount of the vehicle from an output signal of the sensor unit, and determine a correction factor based on the wheel slip amount,
- determine a corrected model speed from a predetermined model speed for a motor of the vehicle based on the correction factor and the first motor speed,
- determine the vibration component based on the motor speed and the corrected model speed, and generate an anti-jerk torque based on the determined vibration component, and
- generate a final output torque of the motor based on a driver demand torque of the vehicle and the generated anti-jerk torque.
