Problems solved by technology

Although the technical solution of this patent has the function of detecting obstacles in the blind zone and giving an alarm, the technical solution of this patent is only applicable to the detection and alarm of static obstacles, and is not suitable for the detection of dynamic obstacles during driving. with alert
The reason is: when the distance is far but the relative speed is high, there is still the possibility of collision, but the technical solution of this patent cannot effectively detect and warn

Embodiment Construction

[0028] The following are specific embodiments of the present invention and in conjunction with the accompanying drawings, the technical solutions of the present invention are further described, but the present invention is not limited to these embodiments.

[0029] An automobile steering assistance system includes a distance detection module, a duration module, a processing module and an alarm module. The distance detection modules are arranged on the side of the vehicle body. There are multiple distance detection modules. The distance detection modules are distributed between the front and the rear of the vehicle, and the detection ranges of the distance detection modules intersect each other. Thus, during the steering process of the vehicle, if an obstacle enters the detection range of the distance detection module, different distance detection modules can detect a set of distance parameters. At the same time, when the distance detection module detects an obstacle, the durat...

Abstract

The invention relates to the technical field of automobiles, in particular to an automobile steering auxiliary system. The system comprises a distance detection module, a duration module, a processing module and an alarm module. The distance detection module is arranged on the side of the body; the distance detection module is used for detecting the distance between the vehicle body and an obstacle in real time to obtain a distance parameter; the duration module is used for starting timing to obtain a duration parameter when the distance detection module detects the obstacle; the processing module is used for calculating the relative speed according to the distance parameter and the duration parameter; the processing module is used for calculating theoretical impact duration according to the distance parameter and the relative speed; the processing module is used for comparing the theoretical impact duration with the reaction duration and obtaining a comparison result; and the alarm module is used for sending out corresponding alarm information according to the comparison result. A detection mode in the prior art is not suitable for dynamic obstacles. Compared with the prior art, by comparing the theoretical impact duration with the reaction duration, dynamic obstacles can be effectively detected and alarmed.

Description

technical field [0001] The invention relates to the technical field of automobiles, in particular to an automobile steering assist system. Background technique [0002] With the continuous development of technology and the gradual increase of car ownership, the driving safety of cars has gradually become the focus of people's attention. At present, cars are equipped with a large number of auxiliary systems, especially for obstacle detection and corresponding alarm systems in the driving blind spot when the car is turning. This type of system has a major impact on the driving safety of the car. [0003] A Chinese patent discloses an automobile intelligent assisted steering system [Application No.: 201811044867.1, Publication No.: CN109353273A] The technical solution of this patent obtains the distance between the vehicle and the obstacle, and combines the obtained distance with the set warning distance Compared with the threshold value, the corresponding alarm is issued acc...
