Intelligent automatic emergency brake system and method

Abstract

The invention relates to the technical field of vehicle emergent brake, in particular to an intelligent automatic emergency brake system and method. The intelligent automatic emergency brake system comprises a vehicle electronic stable control system, a gearbox, a vehicle body controller, an engine and an automatic emergency brake unit. If a vehicle collides, the automatic emergency brake units automatically store driving and traffic environment information collected from a CAN line before collision happens; and on the premise that the cost is not increased, driving record functions can be achieved only through an original automatic emergency brake unit, driving and traffic environment information and more information can be recorded, after the traffic accident happens, the responsibility of double parties can be clearly divided, and disputes are avoided.

Description

technical field [0001] The invention relates to the field of vehicle active safety, in particular to an intelligent automatic emergency braking system and method. Background technique [0002] With the rapid development of the global automobile industry, the number of automobiles has also increased dramatically, and vehicle traffic accidents have also increased. In order to reduce collision accidents and reduce injuries caused by collisions, more and more vehicles are equipped with automatic emergency braking systems (Automatic Emergency Brake System, AEB), and E-NCAP (EU New Car Certification Program / Center) will implement automatic emergency braking in 2014. As a bonus item, the automatic emergency braking system has gradually become a mandatory installation system. At the same time, in order to accurately record the process of collision accidents and facilitate the division of responsibilities between the two parties, more and more car owners choose to install car drivin...

AI Technical Summary

Problems solved by technology

The traditional automatic emergency braking system can only achieve collision avoidance or collision mitigation, but cannot record the traffic environment information and vehicle operation information before the collision, let alone provide valuable information for accident handling after the collision

[0005] The traditional driving recorder can only record the traffic picture information in front of the vehicle, but cannot obtain the specific information of the target in front of the vehicle, such as relative distance, relative speed, etc., and cannot record the running information of the vehicle and the driver's operation when an accident occurs. Such as vehicle speed during collision, vehicle acceleration and deceleration, whether to turn, accelerator pedal information, brake pedal information

Therefore, after the traffic accident occurs, the responsibilities of both parties cannot be clearly divided.
