Automatic parking control method based on main driving door opening and seat departure detection Technical Field The invention relates to the technical field of vehicles, in particular to an automatic parking control method based on main driving door opening and seat departure detection. Background With the continuous improvement of the level of electronics and intelligence of new energy automobiles, an electronic parking brake system (EPB) and an automatic parking function (auto) have become mainstream configurations. The existing automatic parking technology is mainly divided into two types, namely conventional automatic parking triggered by stepping on a brake pedal, braking and maintaining are realized by means of an ESP hydraulic system or an EPB motor, and release can be realized by lightly stepping on an accelerator, and auxiliary parking control combined with a safety belt and a vehicle door state is adopted, wherein part of vehicle types trigger parking braking to avoid risks when a driver does not tie the safety belt or open the vehicle door.

For example, when a driver is driving at a low speed, the driver temporarily opens the door (such as taking objects and observing road conditions), part of the system can directly cut off power or switch to a P gear, which is contrary to the original driving intention and affects the driving smoothness, and the other part of the system does not take any braking strengthening measures, so that accidents are easily caused by the running of the vehicle, and particularly, the problem of insufficient braking holding force is more remarkable in a ramp scene. The misoperation is not enough in protection and the safety redundancy is low Aiming at misoperation of a driver (such as releasing a brake pedal in a state of unbuckled safety belts and opening doors), the prior art lacks a progressive safety protection mechanism. And in addition, the collision between the vehicle type braking and gear switching logic is easy to cause system response delay or functional failure, and collision accidents are easy to be caused under the scene of road sections, slopes and the like.
