The Smart City Brake Support (SCBS) system alerts the driver of a possible collision using an indication in the display and a warning sound when the Forward Sensing Camera (FSC) detects a vehicle ahead and determines that a collision with a vehicle ahead is imminent. In addition, the system reduces damage in the event of a collision by operating the brake control when the system determines that a collision is unavoidable. It may also be possible to avoid a collision depending on the relative speed between your vehicle and the vehicle in front of you. In addition, when the driver depresses the brake pedal, the brakes are applied firmly and quickly to assist.
