Problems solved by technology

The problem brought about by this in reality is that if a car equipped with an AEB system brakes suddenly due to the road conditions ahead, other vehicles that are not equipped with an AEB system may not be able to react in time (especially when a large vehicle is overloaded and the brake system fails, or driver fatigue / distracted driving), the resulting rear-end collision accidents are more serious than those without AEB technology

Embodiment Construction

[0020] Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

[0021] figure 1 is a schematic diagram of a vehicle running on a road according to an embodiment of the present invention. Such as figure 1 As shown, a vehicle 1 equipped with an automatic emergency braking (AEB) system is running on the road, and the activation time Δt of the automatic emergency braking system of vehicle 1 is AEB It is preset at the factory. From figure 1 It can be seen that the front vehicle 0, such as a car, is driving in front of the vehicle 1, and the rear vehicle 2, such as a large truck, is driving behind the vehicle 1.

[0022] During the driving process, when the front vehicle 0 decelerates or brakes urgently, vehicle 1 will make a judgment based on the vehicle information of the front vehicle 0 and the rear vehicle 2, and when it is found that there is a risk that the rear vehicle 2 will collide with vehicle 1, An e...

Abstract

The present invention relates to a collision avoidance method and system for a vehicle, the method comprising: obtaining vehicle information of a preceding vehicle and a following vehicle; and issuing an early warning and restricting the vehicle according to the obtained vehicle information of the preceding vehicle and the following vehicle Activate its automatic emergency braking system. The method and system can avoid the risk of the vehicle being rear-ended by a rear vehicle due to emergency braking due to the road conditions ahead.

Description

technical field [0001] The invention relates to the field of automobiles, in particular to an anti-collision method and system for risk warning and avoidance of vehicle rear-end collisions. [0002] technical background [0003] Automatic Emergency Braking (AEB) is a car driving assistance technology. The AEB system uses radar to measure the distance to the vehicle in front or obstacles, and then uses the data analysis module to compare the measured distance with the warning distance and safety distance. When the warning distance is reached, the warning will be given, and when the distance is less than the safe distance, even if the driver does not have time to step on the brake pedal, the AEB system will be activated to enable the car to automatically brake, thereby ensuring travel safety. [0004] Currently in China, AEB systems are usually installed in cars, while large vehicles (such as trucks, trucks, buses) generally do not install AEB systems. In fact, for a long peri...
