Automatic parking system

Abstract

The invention relates to an automatic parking system. The automatic parking system comprises an environment acquisition sensor used for detecting the surrounding environment of a vehicle, and sending the acquired data to a central processing unit, a human-computer interaction unit used for providing an interface for observing the surrounding environment information of the vehicle and interacting with the system by a driver, the central processing unit used for creating a parking environment map according to the received surrounding environment data of the vehicle and sending the parking environment map to the human-computer interaction unit, planning an expected parking path according to the received parking space selection information of the driver, the acquired actual position information of the vehicle and the parking environment map and sending the expected parking path to a bottom-layer control module, and the bottom-layer control module used for triggering the vehicle to carry out a corresponding operation according to the expected parking path sent by the central processing unit, so as to finish parking. The fully-automatic parking technology disclosed by the invention solves the problems that a parking space is narrow and a common driver difficulty parks the vehicle in place, which are brought by an urbanization process, and has a re-planning capacity.

Description

Technical field [0001] The present invention relates to the field of automobile technology, in particular to an automatic parking system. Background technique [0002] Many companies and institutions have carried out research and development of automatic parking systems, and this function has also been applied in existing mid-to-high-end passenger car models. [0003] The general process of the existing parking plan is as follows: [0004] First, the driver turns on the parking function and drives through the parking area at a speed less than a certain value (for example: 35km / h). At this time, the on-board sensor system starts to work. After the system detects a suitable parallel or vertical parking space, it will prompt the driver to continue moving forward. After reaching the position deemed suitable by the system, the system prompts the driver to stop and engage in R gear, and then the central processor analyzes and processes the collected environmental information. , Get the c...

AI Technical Summary

Problems solved by technology

[0006] 1. At the beginning of parking, the driver needs to park the vehicle at the designated location first. If the vehicle is outside the designated range, the system cannot plan the expected parking path, that is, the parking system cannot start working;

[0007] 2. The existing automatic parking system is only applicable to the specific parking types preset by the system, such as parallel or vertical, and it will not be able to realize the identification of parking spaces and parking spaces for any type of parking space around the vehicle;

[0009] 4. Today's automatic parking system only takes over the lateral control of the vehicle, and the longitudinal control of the vehicle, such as shifting and braking, still requires the driver to complete, so it is a semi-autonomous automatic parking system
