Automatic parking system of information fusion of multiple sensors

Abstract

The invention relates to an automatic parking system of information fusion of multiple sensors. The automatic parking system comprises an ultrasonic control module, an image processing module, an electronic assisting steering control module, a speed control module and a finished vehicle control module. The ultrasonic control module can collect the distance between a parking space and a vehicle and between surrounding obstacles and the vehicle so as to achieve the function of recognizing the parking space. The image processing module can collect parking environment information surrounding the vehicle and adjust a virtual parking space in an image so as to achieve the function of parking space matching. The electronic assisting steering control module can perform steering control of the vehicle according to track information so as to achieve the track control function. The speed control module can control the running speed of the vehicle so as to achieve the low-speed control function of the vehicle. The finished vehicle control module can generate a parking track according to the position relation between the vehicle and the parking space, wherein the position relation is obtained according to an image processing system. In addition, the finished vehicle control module can generate a corresponding control signal to control the vehicle to finish parking operation.

Description

technical field [0001] This article relates to the field of smart car technology, especially an automatic parking system based on multi-sensor information fusion, which can be applied to the occasion of automatic parking of vehicles. Background technique [0002] With the rapid development of the economy, the living standards of residents continue to improve, and the pursuit of material goods is also constantly changing, especially in the way of travel. As of August 16, 2011, the total number of vehicles in use worldwide, including cars, trucks and buses, has exceeded 1 billion. The number of residents' cars is increasing, which brings huge pressure to the traffic in large, medium and small cities. The streets and alleys are often blocked. Urban road resources are becoming increasingly scarce, and parking spaces are becoming increasingly scarce. In order to be able to build more parking spaces, The size of the parking space is designed very harshly, and the problem of diffi...

AI Technical Summary

Problems solved by technology

First of all, the ultrasonic sensor cannot work normally due to the limitations of its working conditions, obstacle types, blind spots and interference problems; secondly, in the process of parking, the ultrasonic sensor cannot dynamically feed back the real environmental information in real time, so that the driver can There are great concerns in using the parking system
