Vehicle turning blind spot early warning method and system

Abstract

The invention provides a vehicle turning blind spot early warning method. The vehicle turning blind spot early warning method comprises the steps that whether a vehicle is in a turning state or not isjudged; if so, real-time turning angles of inner front wheels on the turning inner sides of the vehicle are collected, and an early warning area is established according to vehicle parameters; whether dangerous object intrusion exists on the turning sides of the vehicle or not is monitored; if so, position information of a dangerous object is collected, and a warning signal I is sent to a driver;the position information of the dangerous object is compared with the position of the early warning area to determine whether the early warning area is located or not; and if so, a warning signal IIis sent to the driver. The buffer early warning area is additionally arranged, a basic early warning area of the inner wheel difference is expanded, a two-level early warning area is established, theintrusion situation and the position information of the dangerous object in the early warning area are monitored in time, the voice early warning prompt is provided for the driver, and meanwhile, reference information for the position of the dangerous object for active avoidance decisions is provided for the driver.

Description

technical field [0001] The invention belongs to the technical field of automotive electronics, and in particular relates to a vehicle turning blind zone early warning method and system. Background technique [0002] In recent years, with the rapid development of our country's economy, our country has become a veritable automobile power. However, the increase of automobiles has also brought more traffic accidents, among which the accident of large vehicles is one of the main causes of major traffic accidents. The inner wheel difference refers to the difference between the turning radius of the front inner wheel and the rear inner wheel when the vehicle is turning. Due to the existence of the inner wheel difference, when the vehicle is turning, the trajectories of the front and rear wheels do not coincide. If you only pay attention to the passage of the front wheel and forget the inner wheel difference during driving, it may cause the rear inner wheel to drive out of the road...

Problems solved by technology

Due to the existence of the inner wheel difference, when the vehicle is turning, the trajectories of the front and rear wheels do not coincide. If you only pay attention to the passage of the front wheel and forget the inner wheel difference during driving, it may cause the rear inner wheel to drive out of the road or collide with other objects. collision accident

At present, there are still the following problems in the research on the inner wheel difference: 1. The method of expanding the field of view of the rearview mirror cannot completely eliminate the blind area of ​​the inner wheel difference. Other motor vehicles or pedestrians in the past cause certain visual interference. On the other hand, the driver still cannot obtain blind spot information to make active decisions to avoid danger.
