Vehicle Peripheral Recognition Device

Abstract

The present invention relates to a vehicle-mounted peripheral recognition device, comprising: a front sensing part, the front sensing part consists of a front short-distance sensor installed on the top of the vehicle windshield in order to sense obstacles within short distances in the front of the center of the vehicle and in the left and right fronts. , and in order to perceive obstacles within the front of the vehicle, the front ultra-close sensor installed on the front bumper of the car; the rear sensing part, the rear sensing part includes a rear ultra-close sensor for sensing obstacles within the ultra-close distance behind the vehicle a distance sensor; a first control unit, which detects a parking space according to the sensing signal input from the front sensing unit and the sensing signal input from the rear sensing unit; and a second control unit, which controls the The part detects the parking space according to the sensing signal input by the front sensing part. With this feature, the recognition function of the automatic parking assistant and the emergency control assistant can be improved.

Description

technical field [0001] The invention relates to a vehicle-mounted peripheral identification device, which combines a laser sensor and an ultrasonic sensor to improve the identification performance of parking areas and surrounding obstacles. Background technique [0002] Generally, the Smart Parking Assistance System (Smart Parking Assistance System; hereinafter referred to as "SPAS") detects the parking space, and automatically controls the steering wheel, and cooperates with the driver to control the brakes to complete the parking action. [0003] SPAS installs multiple ultrasonic sensors on the car in order to identify obstacles and measure distances, and to detect parking areas and obstacles in front of, behind and on the side of the vehicle. [0004] On the one hand, Emergency Brake Assist (hereinafter referred to as "EBA") is a system that recognizes obstacles approaching ahead and automatically decelerates. In order to detect obstacles ahead, a laser sensor is installe...

AI Technical Summary

Problems solved by technology

[0007] However, due to the limitations of the ultrasonic sensor or the limitations of the installation position and direction, there is a problem of high possibility of misidentification or non-identification

[0008] That is, when other objects around or ultrasonic sensors installed on other vehicles are in operation; when the road slope is very large; when the ultrasonic sensor is exposed to the outside of the vehicle and the sensor surface is contaminated; when the ultrasonic sensor is loaded at a height or position and angle are deformed; Sensor limitations or restricted loading position and orientation, high chance of misidentification or non-identification

[0009] In addition, due to the limitation of the loading position and direction of the laser sensor, EBA may misidentify or fail to identify very low approaching obstacles to the front, and there are such problems
