Benefits of technology

The present technology provides for automatically starting up or stopping down doors with minimal interference from objects that may be hidden behind them by their position within its range. This helps prevent damage caused when people enter through locked windows during emergency situations like fires.

Problems solved by technology

Technological Problem: Current automatic systems are unable to accurately detect objects near an opening or closing point on a vehicle's exterior without manual intervention by operators who may be approaching them with their hands during starting/stopping operations that can lead to collisions between cars and other road users.

Abstract

The invention discloses an automatic start and stop method of a car door and a related device. The method comprises the steps of obtaining space coordinates of the car door in a preset three-dimensional coordinate system in real time according to a three-dimensional model of the car door and the opening angle of the car door; obtaining N virtual arc-shaped enveloping surfaces in real time in the mode that an ultrasonic radar detects the obstacle distance, wherein N is a positive integer; calculating the shortest distance between the car door and an obstacle according to the space coordinates of the car door and the virtual arc-shaped enveloping surfaces; and determining whether the shortest distance is larger than a distance threshold value or not, and controlling the car door to stop if the shortest distance is not larger than the distance threshold value. According to the automatic start and stop method, the technical problem that an automatic car door lacks convenience and adaptivity because an existing automatic car door start and stop technique cannot perform adaptive obstacle avoidance on obstacles around the door is solved.
