Abstract

A vehicle assistance apparatus includes an interface unit configured to receive information regarding an electric current provided to a brake lamp of a vehicle. The vehicle assistance apparatus also includes an object detection unit configured to detect an object outside the vehicle, and a processor. The processor is configured to determine, based on the detected object, a speed of the vehicle and also determine, based on the speed of the vehicle and the information regarding the electric current provided to the brake lamp of the vehicle, whether the vehicle undergoes acceleration during a braking operation of the vehicle. The processor is further configured to provide, based on a determination that the vehicle undergoes acceleration during the braking operation of the vehicle, a control signal to restrict further acceleration of the vehicle.
