  • Patent number: 11084498
    Abstract: An apparatus and a method for controlling a driving mode of a vehicle are provided. The apparatus includes a mode converter that converts the driving mode of the vehicle based on an operation of a mode conversion input. When the driving mode is converted into a custom mode, a mode setting screen for adjusting a setting value of a driving characteristic preset is configured and the configured mode setting screen is displayed on a display of the vehicle. A tuning device then tunes a driving characteristic of the custom mode based on a setting value adjusted on the mode setting screen.

  • Publication number: 20210061256
    Abstract: A motor torque control apparatus for a hybrid vehicle includes: a calculator for calculating a model speed of a motor, a control model speed, an anti-jerk torque, and an anti-jerk torque control factor; and a controller for controlling the calculator. At the time of LFU shifting, the controller controls a motor speed using the anti-jerk torque, determines whether the motor speed controlled using the anti-jerk torque is abnormal based on the maximum difference value between the motor speed and the model speed and a reduction in the motor speed, corrects the anti-jerk torque based on the control model speed and the anti-jerk torque control factor upon determining that the motor speed is abnormal, and controls the motor speed using the corrected anti-jerk torque.

  • Patent number: 10144413
    Abstract: An anti-jerk control system and method of an eco-friendly vehicle are provided to prevent a driver from sensing a difference in vehicle starting at an initial stage when the vehicle is parked on a downhill road. The anti-jerk control method uses a motor as a driving source and includes calculating an actual speed of the motor, calculating a model speed of the motor, and acquiring a gradient of a road, on which the vehicle is located, using a gradient detector. Additionally, the method includes determining a speed offset value that corresponds to the acquired gradient, compensating the model speed by the speed offset value, and calculating a motor vibration component using a difference between the compensated model speed and the actual speed of the motor. Then, anti-jerk compensation torque is calculated using the calculated motor vibration component.
