Double-sensor detection based automobile auxiliary early warning method

Abstract

A double-sensor detection based automobile auxiliary early warning method includes: optimally setting first and second detection sensors and height detection sensors to calibrate in advance, scanning a step in a detection direction, calculating to obtain the height of the step and the distance between an automobile and the step, compensating a gap value between the automobile and the ground, judging scratch conditions of the automobile according to different detection periods, alarming in real time and adjusting a driving way. The double-sensor detection based automobile auxiliary early warning method has advantages that a driver can be reminded quantitatively, a detection range is expanded, detection blind areas are avoided, and scratching is prevented effectively.

Description

technical field [0001] The invention relates to the field of vehicle safety, in particular to an automobile auxiliary early warning method based on dual-sensor detection. Background technique [0002] With the development of social economy, vehicles have become the preferred means of transportation for families in modern society, and their number has increased rapidly in the past 10 years. At present, the problem of difficult parking has been highlighted, and the complex parking environment is also increasing day by day. In the process of driving a vehicle, it is inevitable that there will be obstacles that need to pass through, such as the steps that often need to drive up the roadside when parking, etc. In these cases, due to the different structures of vehicles of different brands and models The height between the chassis and the ground is also different, and the driver's judgment on roadside obstacles will also be different, especially when the size of the obstacle is n...

AI Technical Summary

Problems solved by technology

However, although the above method can effectively avoid scratches and collisions, the above method cannot quantitatively prompt the driver, so that when the driver is reminded, the vehicle will also be scratched, especially when it is necessary to drive up the steps.

In addition, since the existing detection methods mostly measure the surrounding obstacles in a parallel or approximately parallel manner, when the obstacles are located below the rear of the vehicle and close to the vehicle, these positions belong to the blind area of ​​detection and cannot be detected. Detection by existing means
