Assisted driving method and system

Abstract

The present invention provides a driving assistance method and system. The driving assistance method includes: collecting a first distance of a target object and collecting a second distance of the target object. The first distance represents the distance between the target object and the first sensor, and the second distance is collected. The second distance represents the distance between the target object and the second sensor; based on the distance between the first sensor and the second sensor, the first distance and the second distance, determine the vertical distance between the target object and the reference line along the The forward direction of the vehicle tires; based on the vertical distance between the target object and the reference line and the width of the vehicle tires, the direction adjustment characteristics of the vehicle are determined. The assisted driving method and system provided by the present invention, by using the first sensor and the second sensor to measure the distance of the target object, determine the direction adjustment characteristics of the vehicle, can realize accurate positioning and detection of small obstacles, perform reasonable obstacle avoidance, and improve Safety performance of vehicle driving.

Description

technical field [0001] The invention relates to the technical field of intelligent vehicles, in particular to a driving assistance method and system. Background technique [0002] When the car is running at a certain speed, it is difficult for the driver to observe some relatively small obstacles on the road ahead, such as some sharp stones or sharp metal blocks, especially some relatively hard objects. , because the tread of the tire has a certain curvature, it is very likely that the pressed object will be squeezed and flew, and the weight of the car itself plus the driving speed will make the pressed object have a great impact At the same time, after some sharp objects are pressed by the tires, they will also cause damage to the tires, so it is necessary to solve the problem of avoiding small obstacles. [0003] At present, the intelligent assisted driving system equipped with the car will sense obstacles on the road through some laser sensors installed on the front of t...

AI Technical Summary

Problems solved by technology

[0004] The present invention provides a method and system for assisting driving, which is used to solve the defects in the prior art that the detection of small obstacles is not accurate enough, and the driver himself is required to maintain vigilance on the road at all times, which affects the safety of driving. Realize the rapid and accurate positioning and detection of small obstacles, and determine the direction of vehicle adjustment, so as to avoid obstacles reasonably and improve the safety performance of vehicle driving
