Problems solved by technology
However, as we all know, there is a positioning error in GPS positioning, especially for occasions where accurate acquisition of position information is required. GPS positioning cannot realize the accurate collection of position information of the vehicle and the vehicle in front, and cannot realize the emergency brake warning of the technical solution of the present application.

Embodiment Construction
[0028] The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.
[0029] see figure 1 , vehicle emergency braking early warning system, the early warning system includes a central processing unit 1 and a power control unit 2, the central processing unit 1 and the power control unit 2 establish a signal transmission relationship, the early warning system also includes an acceleration acquisition module 3, an acceleration Presetting module 4, acceleration determination module 5, pulse modulation module 6 and signal switching module 7;
[0030] The acceleration acquisition module 3 establishes a connection relationship with the central processing unit 1, and the acceleration acquisition module 3 is used to acquire the acceleration information parameters of the vehicle to be warned and deliver the acquired acceleration information parameters to the central processing unit 1;
[0031] The acceleration pr...

The invention relates to a vehicle emergency braking warning system and a vehicle emergency braking warning method, wherein an acceleration warning threshold value for warning when the vehicle is emergency braking is set in advance; acquiring acceleration information parameters of a vehicle to be alerted, and transmitting the acquired acceleration information parameters to a central processing unit; the obtained vehicle acceleration information parameters are compared with the acceleration warning threshold, determining whether to trigger an alert signal; a, when the vehicle acceleration information parameter is greater than the acceleration warning threshold value, no warning signal is triggered, the vehicle is in the normal brake mode, the brake pedal is pressed, the brake light of the vehicle to be alerted is on, the brake pedal is released, the brake light of the vehicle to be alerted is off; b, when the acceleration information parameter of the vehicle is smaller than the acceleration warning threshold value, the warning signal is triggered, and the central processing unit transmits the received warning signal to the power control unit. At the time of the emergency brake / rear-end collision, the invention can give the rear-end vehicle an effective and early war, effectively reduce the accident rate, and in particular can effectively reduce the serial rear-end collision events.
Description
technical field [0001] The invention relates to the technical field of vehicle safety, in particular to a vehicle emergency braking early warning system and method. Background technique [0002] At present, the control mode of the brake light of the vehicle is single, and there is only one mode, or one brightness display. In the existing technical solution, when the vehicle in front adopts normal braking and emergency braking, the brake light has no difference in display mode, and the vehicle behind can only judge the real-time vehicle distance, and take the corresponding braking process through subjective judgment in the brain. In other words, if the vehicle in front has an emergency event, such as an extreme rear-end collision, as the vehicle behind, to effectively deal with this situation, you need to maintain a high degree of concentration at all times, and you need to make quick brain judgments (front emergencies), it is necessary to quickly make physical judgments, an...
