It is disclosed a braking assisting system for a vehicle, comprising: a detection unit adapted to detect the weight of passenger(s) and/or luggage in the vehicle, a braking assisting signal generation unit adapted to generate a braking assisting signal based on the weight detected by the detection unit, a signal transmission unit adapted to receive the braking assisting signal from the braking assisting signal generation unit and transmitting the braking assisting signal to a braking system of the vehicle. By keeping the weight of passenger(s) and/or luggage in the vehicle in consideration and providing such braking assisting signal to the braking system of the vehicle, the braking of the vehicle can be implemented in a more accurate way.
