  • Publication number: 20160368444
    Abstract: A vehicle control unit may be provided that protects passengers of a vehicle while entering and exiting the vehicle. When the door opening closing operation signal or the speed meets a predetermined condition, the vehicle control unit receives information on whether a threat exists in the side or rear of the vehicle. When the threat does not exist, the vehicle control unit outputs the door opening closing operation signal to the door control unit and outputs the acceleration pedal rotation angle to the engine control unit. When the threat exists, the vehicle control unit does not output the door opening closing operation signal to the door control unit or does not output the door opening closing operation signal controlled to prevent the door from being opened to the door control unit and outputs an on-signal to the warning light or the buzzer disposed within the vehicle.
