A collision warning device

Abstract

The invention provides a collision early warning device. A positioning module obtains speed and position data of a mobile platform, and a control module enables the speed and position data to be packaged and sent to a communication module; the communication module sends packaged data, and receives packaged data sent by other mobile platforms; the control module analyzes the received packaged data to obtain speed and position data of the surrounding mobile platforms; the control module controls the sending power and sending frequency of the communication module in a self-adaptive manner; an alarm module receives the speed and position data of each mobile platform and sends an alarm signal to an alarm execution module; and the alarm execution module and a display module receive the alarm signal and execute corresponding operation. The collision early warning device better solves the problem of comprehensive early warning and the problem of restriction of visual range, and meanwhile, increases early warning time, thereby facilitating occurrence rate of collision accidents.

Description

technical field [0001] The invention relates to the fields of motor vehicle safety, automotive electronics and the like, in particular to a vehicle collision warning device. Background technique [0002] Collision is a major cause of traffic accidents. Whether it is a collision between a car and a car, a collision between a car and a non-motor vehicle, or a collision between a car and a person, there will be losses. The rise in premiums in the coming year) and time loss, and in severe cases, the car will be destroyed and people will be killed. [0003] According to statistics, if the warning can be issued 0.6 seconds in advance, more than 60% of traffic collision accidents can be reduced; if the warning can be issued 1.5 seconds in advance, more than 90% of traffic collision accidents can be reduced. As a result, the collision prevention function has attracted a lot of attention in the industry, and some products based on visual perception and products based on lidar detec...

AI Technical Summary

Problems solved by technology

While avoiding forward collisions, these products also have insurmountable deficiencies:

[0004] 1) When only one sensor is installed, a full range of collision warning functions cannot be realized, and the installation of multiple sensors will rapidly increase the complexity of the system;

[0005] 2) The visual perception system cannot overcome the limitation of sight distance;

[0006] 3) The laser radar-based system is limited by the power so that the working distance is small;
