Problems solved by technology

[0003] However, the existing lateral anti-collision warning system mainly has the following problems: (1) At intersections with fast vehicle speeds, the system cannot detect effective targets in time, and cannot play the role of detecting targets; (2) Under dangerous road conditions The system only has a warning function and cannot take any active actions to prevent collisions, that is, there are still potential safety hazards
That is, there is a lack of an intelligent, high-safety vehicle side collision avoidance method, device and system in the prior art

Embodiment Construction

[0014] Specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings. It should be understood that the specific embodiments described here are only used to illustrate and explain the present invention, and are not intended to limit the present invention.

[0015] figure 1 is a schematic structural diagram of an exemplary vehicle side collision avoidance device according to an embodiment of the present invention, and the device may include: a receiving module 100, configured to receive a vehicle side collision avoidance activation signal;

[0016] The measurement module 200 is configured to determine whether there are other vehicles within the detection range when the vehicle lateral collision avoidance activation signal is received, and measure the distance between the vehicle and other vehicles if there are other vehicles within the detection range. Relative speed, relative distance, and relative angle; and a pr...

Abstract

The invention discloses a vehicle lateral collision prevention method, device and system. The method includes: receiving a vehicle side collision prevention start signal; when the vehicle side collision prevention start signal is received, judging whether other vehicles are in a detection range or not; when other vehicles are in the detection range, measuring relative speed, relative distance and relative angle of the vehicle relative to other vehicles; calculating collision time of the vehicle with other vehicles according to the relative speed, relative distance and relative angle, and performing collision prevention operations according to the calculated collision time. The vehicle lateral collision prevention method, device and system has the advantages that safety accidents can be prevented effectively, driving the vehicles is safer and more intelligent, and practical value is high.

Description

technical field [0001] The present invention relates to the field of automobiles, in particular to a vehicle side collision avoidance method, device and system. Background technique [0002] Intersections and areas where vehicle accidents frequently occur, the existing lateral collision avoidance technology mainly uses multi-function cameras, ultrasonic radar, etc. to detect the surrounding environment and road vehicle conditions in real time, when the camera or ultrasonic radar detects potential collisions around the vehicle In case of danger, the driver is reminded to maintain an appropriate lateral distance through sound, flashing lights, etc., so as to prevent collisions between vehicles and vehicles, and between vehicles and road guardrails. [0003] However, the existing lateral anti-collision warning system mainly has the following problems: (1) At intersections with fast vehicle speeds, the system cannot detect effective targets in time, and cannot play the role of d...
