Auxiliary driving method and system

Abstract

The invention provides an auxiliary driving method and system, and the method comprises the steps: collecting a first distance of a target object, and collecting a second distance of the target object, the first distance representing the distance between the target object and a first sensor, and the second distance representing the distance between the target object and a second sensor; based on the distance between the first sensor and the second sensor, the first distance and the second distance, determining the vertical distance between the target object and a reference line, and the reference line is in the advancing direction of the vehicle tire; and determining a direction adjustment feature of the vehicle based on the vertical distance between the target object and the reference line and the width of the vehicle tire. According to the auxiliary driving method and system provided by the invention, the first sensor and the second sensor are used for measuring the distance of the target object and determining the direction adjustment characteristics of the vehicle, so that small obstacles can be accurately positioned and detected, reasonable obstacle avoidance is carried out, and the safety performance of vehicle driving is improved.

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
