Automatic parking method and system based on optimal path

Abstract

The invention discloses an automatic parking method and system based on an optimal path. By means of an environment data acquisition module being composed of a look-around camera and an ultrasonic radar, the vehicle parking environment data is acquired and whether the parking space is suitable for parking or not is judged; a central processing unit module calculates and analyzes the position relation between the vehicle body and the parking space, generates an optimal parking path, and finally sends the optimal parking path to the vehicle executing mechanism module to control the gear, steering, braking, accelerator and other control quantities of the vehicle, so that the effect of automatic parking is achieved. A man-machine interaction module displays the current state information, environmental parameters and operation steps of the automobile through the display screen, a driver can select whether to enter a parking state or not or stop the automatic parking process in real time, and the beneficial effects of being more practical, more convenient, more accurate, safer and the like are achieved.

Description

technical field [0001] The invention relates to the technical field of automobile electronic control, in particular to an automatic parking method and system based on an optimal path. Background technique [0002] With the increasing popularity of car parking automation systems, the practicability, convenience and safety of automatic parking systems are all concerned by drivers. The automatic parking system can improve the efficiency of parking, reduce the fatigue of the driver during the parking operation, reduce the incidence of parking accidents, reduce the number of parking accidents, and help ensure the integrity of roads, parking lots and other public facilities and security. [0003] At present, in the automatic parking systems that have been commercialized, most of the low-end systems use ultrasonic sensors alone as the environment acquisition module, but this kind of parking system can only detect parking spaces with physical obstacles; or use a separate camera as ...

AI Technical Summary

Problems solved by technology

The current automatic parking solution requires the driver to manually search for a parking space in some scenarios, but does not achieve fully automatic parking; the multi-sensor fusion automatic parking solution based on radar and camera can identify parking spaces in complex scenarios And realize fully automatic parking, but there are many time-consuming, large amount of calculation, and the shortcomings of the whole system are expensive

Most of the existing automatic parking solutions do not model the vehicle kinematics during the parking process, and do not optimize the generated parking path, which often makes the actual parking path unreasonable, time-consuming and easy to encounter. surrounding obstacles
