Door opening early warning system and method

The invention discloses a door opening early warning system and method.According to the system, an outside-vehicle sensing module monitors information of a rear target outside a vehicle in real time, and when it is judged that the rear target information affects a door opening action, a door opening early warning signal is output; the vehicle door electronic switch monitoring module is responsible for monitoring the current vehicle door electronic switch state, and when a door opening request is monitored, a door opening request signal is output. And finally, the weak electric shock module outputs weak voltage so as to carry out early warning on people in the vehicle which pre-open the vehicle door. According to the early warning system, when the vehicle detects that a user has the intention of opening a door and getting off the vehicle and monitors the condition of target information such as vehicles or pedestrians outside the vehicle, corresponding responses are made, when potential safety hazards exist, we
