Automobile and its obstacle avoidance control method

Abstract

The present invention proposes a car and its obstacle avoidance control method, wherein the car is provided with a laser detection device, and the method includes the following steps: acquiring road condition information in front of the car; judging whether there is a vehicle within a preset distance in front of the car according to the road condition information ; If there is no vehicle within the preset distance in front of the car, control the car to turn on the laser obstacle detection function; after the car turns on the laser obstacle detection function, detect the roadblock information in front of the car in real time through the laser detection device; according to the roadblock information, the car performs obstacle avoidance control. The obstacle avoidance control method of the automobile can accurately judge obstacles, so as to control the automobile to move forward and overcome obstacles more correctly, improve driving efficiency, and avoid unnecessary parking.

Description

technical field [0001] The invention relates to the technical field of automobiles, in particular to an automobile obstacle avoidance control method and an automobile. Background technique [0002] At present, the self-driving technology of cars is still immature, and most of them are still in the experimental stage. An important issue in unmanned driving technology is how to effectively detect obstacles when there are obstacles on the road, such as pits and objects protruding from the road, so as to ensure the effective control of the car. [0003] In order to realize the obstacle avoidance control of the vehicle, the obstacle detection methods in the related art include: using ultrasonic obstacle detection, comparing and photographing image obstacle detection, and the like. However, the ultrasonic obstacle measurement error (meter level) is large, and only simple and basic obstacles can be judged, and most obstacles on the road cannot be accurately measured; when using im...

AI Technical Summary

Problems solved by technology

However, the ultrasonic obstacle measurement error (meter level) is large, and only simple and basic obstacles can be judged, and most obstacles on the road cannot be accurately measured; when using image comparison and judgment, the influence is mostly captured by tilting It is impossible to accurately judge the size of obstacles, let alone the depth of concave obstacles and the height of convex obstacles

Therefore, whether it is ultrasonic obstacle detection or image obstacle detection, the obstacle avoidance control of the car will be relatively extensive, which cannot meet the user's obstacle avoidance requirements for the car, and it is easy to cause traffic jams and even accidents due to parking for no reason.
