  • 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.

  • Patent number: 10988046
    Abstract: A method for setting an electric vehicle (EV) on/off line of a hybrid vehicle considers a driving load of the vehicle by setting the EV on/off line based on a climbing angle and creep power. The method for setting the EV on/off line of the hybrid vehicle includes an operation of setting a region according to a state of charge (SOC), an EV online setting operation based on a climbing angle of the vehicle, and an EV offline setting operation based on creep power of the vehicle. The method provides a simple and intuitive EV line setting method to reduce a mapping time and substantially eliminate the possibility of human error, thus increasing logic reliability, so as to reduce use of a hybrid control unit (HCU) memory and provide cost-saving effects.
