Embodiment Construction

[0020] The emergency braking alarm system of the vehicle obtains the current vehicle speed signal and the vehicle acceleration signal through the body control module 2, and outputs an alarm signal to the left and right turn signals 5 and the horn 6 to perform an alarm, such as figure 1 As shown, the vehicle body control module 2 obtains the current vehicle speed signal through the anti-lock braking device 1 , and the vehicle body control module 2 obtains the vehicle acceleration signal through calculation of the change amount of the current vehicle speed signal.

[0021] When the car crosses the speed bump or pothole on the road, the wheels will hang in the air, and the speed will change, which will cause the calculation error of the body control module 2, and the emergency brake sound and light alarm function will be triggered by mistake. At this time, we want to reduce this false trigger. Behavior, must be optimized on the BCM2 acceleration algorithm:

Abstract

The invention discloses a vehicle emergency braking alarm system. The vehicle body control module acquires the current vehicle speed signal and vehicle acceleration signal, and outputs the alarm signal to the left and right turn signals and the horn to perform an alarm. The invention can improve the safety of the vehicle when driving , Intelligent and reasonable alarm, reminding the car behind that the current vehicle is braking urgently, reducing the possibility of rear-end collision accidents.

Description

technical field [0001] The invention relates to the field of vehicle safety. Background technique [0002] With the popularity of vehicles, people have higher and higher requirements for the safety performance of vehicles. Therefore, there are a large number of active and automatic safety devices in vehicles. However, emergency braking during driving may easily lead to rear-end collisions and traffic accidents. An alarm prompt system that warns vehicles behind during emergency braking. Contents of the invention [0003] The technical problem to be solved by the present invention is to realize a system that can give an alarm to prevent rear-end collisions and ensure the safety of drivers and passengers when a vehicle brakes in an emergency. [0004] In order to achieve the above object, the technical solution adopted by the present invention is: vehicle emergency braking alarm system, the vehicle body control module obtains the current vehicle speed signal and vehicle acce...
