Vehicle-mounted ultrasonic sensor system

Abstract

The invention discloses a vehicle-mounted ultrasonic sensor system comprising a data acquisition system, a parking control module, a vehicle control system and a man-machine interactive system, wherein the data acquisition system collects data in different directions of a vehicle; the parking control module identifies the size of an unoccupied space around the vehicle and position information of the to-be-parked vehicle relative to a parking space, judges whether the size of the unoccupied space is larger than a set threshold value, plans a parking path according to the position information ofthe to-be-parked vehicle relative to the parking space, generates a control instruction, and divides parking state information according to the size of the unoccupied space around the vehicle; the vehicle control system controls a vehicle according to the control instruction output by the parking control module; and the man-machine interactive system includes control software and is used to receive vehicle data information and various data information of the vehicle-mounted ultrasonic sensor system, including a drawing area interface and an information display interface. The drawing area interface displays a vehicle model in real time, planned paths in the vehicle parking process and a vehicle real traveling track. The information can be displayed in real time, and the parking safety is ensured.

Description

technical field [0001] The invention belongs to the technical field of parking, and in particular relates to a vehicle automatic parking control system based on a vehicle-mounted ultrasonic sensor. Background technique [0002] With the development of society, the number of automobiles is constantly increasing, and accidents occur frequently when parking out of a parking space. Therefore, many vehicle-mounted parking systems based on the function of parking out of a space have appeared on the market. However, the traffic accidents caused by the process of leaving the parking space from the parking space during parking are also increasing day by day, so people also put forward higher requirements for the convenience of the process of parking. Inconvenience to people, eliminate unsafe factors in driving. [0003] The automatic parking system collects external parking space information, generates a parking control algorithm, guides the driver or directly controls the steering ...

AI Technical Summary

Problems solved by technology

[0005] 1. The automatic parking control module (APA) is responsible for the parking control algorithm, but the existing APA control module either does not consider the functional safety requirements, or cannot meet the ASIL D level, resulting in the entire automatic parking system not meeting ASIL D requirements Requirements, prone to vehicle steering hazards, resulting in hazardous accidents

[0006] 2. It is very difficult and costly to develop an APA control module that meets the requirements of ASIL D, which does not meet the consideration of vehicle economy
