Road condition recognition-based auxiliary vehicle driving method

Abstract

The invention discloses a road condition recognition-based auxiliary vehicle driving method. The method comprises a two-axis turntable structure, a laser sensor module, an MCU control module and a point cloud data processor, wherein the laser sensor module is arranged at the upper part of the two-axis turntable structure; the laser sensor module and the road ground obtain a three-dimensional pointcloud image; an image sensor module is arranged in the laser sensor module; the three-dimensional point cloud image is connected with a three-dimensional surveying and mapping module; the three-dimensional surveying and mapping module is connected with a processor module through a route control module; the processor module is connected with a wireless communication module through the point clouddata processor; and the wireless communication module is connected with a road condition information summarization module. According to the method, a road three-dimensional system of the whole route is formed through changing the mounting positions of the sensors and concentrating and summarizing the obtained pavement information, and the vehicles can obtain the road condition information of the road before arriving at the road, so that route adjustment and reasonable speed planning can be carried out in advance.

Description

technical field [0001] The invention relates to the technical field of automobile auxiliary driving, in particular to an auxiliary vehicle driving method based on road condition recognition. Background technique [0002] By installing sensors with laser, image, and sound as carriers on the car, the car can automatically adjust the running direction and speed, but the ability to recognize the road surface is relatively weak, especially when the car encounters complex road conditions when driving at high speed The problem of speed adjustment and road selection under the environment has not been solved well. In the prior art, most of the systems for detecting road surface information are placed on the car, but the surveying and mapping during the movement has deviations, and it is impossible to obtain accurate road surface information. In order to obtain the specific information of road conditions in the prior art, it is obviously not enough to perceive through the moving car. ...
