Problems solved by technology

However, it takes a certain amount of time for the rear car to observe that the brake light of the front car is on, and for the driver to react and perform the braking operation. In the case of high speed, close following distance or heavy rain or foggy weather, it is easy to cause the brake failure in time. rear end

Embodiment Construction

[0041] The present invention will be described in further detail below with reference to the accompanying drawings and specific embodiments.

[0042] see figure 1 , the embodiment of the present invention includes a target detection and identification module, a distance measurement and planning module, a brake light activation control module, etc.; specifically includes a camera, a radar, a target in front of the vehicle, a controller, a vehicle CAN network, an adaptive brake light, etc. .

[0043] see figure 2 , the specific functions of the target detection and identification module are as follows:

[0044] 1. Activate the camera to identify the driving environment around the vehicle, and determine that there is an obstacle-free target in front of the vehicle;

[0045] 2. The camera remains active continuously. If there is no obstacle in front of the vehicle and the vehicle is driving normally, the camera continues to obtain the surrounding environment of the vehicle;

Abstract

According to the braking early-warning rear vehicle prompting system and method, different driving environments are recognized and judged through the camera and the radar, the driving state of the vehicle is judged, and the function that the braking lamp is activated to conduct braking early-warning prompting on the rear vehicle while the normal braking early-warning function of the vehicle is guaranteed is achieved. According to the method, rear-end collision accidents caused by untimely braking of the rear vehicle are reduced, the safety performance of the vehicle and the driving experience of a driver are improved, the occurrence frequency of traffic accidents such as rear-end collision or rubbing is reduced, and the travel safety and property of customers are protected. According to the method and the system, the braking response time of a driver of the rear vehicle is indirectly prolonged by carrying out braking early warning prompt on the rear vehicle especially for the driving environment with poor sight such as heavy rain and heavy fog, braking preparation is made in advance, and rear-end collision accidents caused by emergency braking of the front vehicle are avoided. According to the invention, new functions are added by using existing hardware, the cost of newly added hardware is saved, and the system is simple and practical, is suitable for all vehicle types and can be modularly operated.

Description

technical field [0001] The invention belongs to the technical field of vehicle brake early warning, and in particular relates to a system and method for warning rear vehicle after brake early warning. Background technique [0002] With the rapid development of the automobile industry, automobiles have become a necessary tool for people to travel, which also brings about the problem of driving safety. With the gradual maturity of electronic information technology, more and more sensors are used to improve the safety performance of automobiles. Among them, the automatic emergency braking system AEB (Autonomous Emergency Braking, through the control module ECU, ranging module and braking module for braking early warning and emergency braking) is an active safety technology for automobiles. In terms of movement and other aspects, it escorts the safe travel of the car. The adaptive brake light ABL adjusts the brightness of the brake light to display the emergency degree of brak...
