The invention belongs to the technical field of traffic safety, and provides a vehicle door opening control system and method based on ultrasonic wave speed measurement. The vehicle door opening control system comprises a speed measurement and comparison circuit, a center control circuit, a trigger control circuit, an execution circuit and a power supply circuit. The speed measurement and comparison circuit measures the speed of a coming vehicle through an ultrasonic wave sensor arranged on a vehicle, compares the speed with a preset value and outputs the comparison result to the trigger control circuit. The center control circuit obtains a turn-on or turn-off signal of a center control switch on the vehicle and outputs the signal to the trigger control circuit. The trigger control circuit outputs a control signal to the execution circuit according to received information. The execution circuit controls a vehicle door lock motor to rotate forwards or backwards according to the control signal, and therefore a vehicle door lock switch is controlled to be turned off or turned on. The power supply circuit is used for supplying power to the control system. According to the vehicle door opening control system and method, the speed of the rear coming vehicle is detected, an alarm is given and a vehicle door is locked when the speed is too high, it is avoided that a traffic accident happens after the vehicle door is opened by a passenger, and the traffic safety is improved.
Description
technical field [0001] The invention belongs to the technical field of driving safety, and in particular relates to a vehicle door opening control system and method based on ultrasonic speed measurement. Background technique [0002] At present, with the development of science and technology and the improvement of economic level, the automobile industry has developed rapidly and has become a tool for people to go out. However, many problems have appeared when automobiles have entered thousands of households, and traffic accidents have followed. Frequent occurrence, resulting in great personal injury and property damage. Among them, accidents of casualties caused by passengers opening doors carelessly occur every year. [0003] When the occupants of the car open the door, they often can only rely on human eyes to identify whether there is a vehicle or pedestrian passing by the side of the door. Opening the door and getting off leads to the generation of traffic accidents, a...
