Problems solved by technology

However, this method is active detection and passive induction, and is affected by the driving speed and driving environment, and the anti-rear collision effect is not satisfactory.
In addition, the cost of existing active detection devices is relatively high, and the implementation method is quite complicated. They can only be installed on relatively high-end cars, and it is not easy to popularize them.

Embodiment 1

[0018] Such as figure 1 As shown, the automobile active warning and anti-rear collision device includes a detection and sensing device 1 , a main processor 2 and an audible and visual warning device 3 which are electrically connected in sequence. The detection and sensing device 1 of this embodiment is a displacement sensor. The displacement sensor is connected to the brake pedal of the automobile and can output a detection signal to the main processor 2 according to the detected displacement of the brake pedal. The main processor 2 receives signals from the detection sensor. The output signal of device 1, judges whether to exceed the preset threshold, to decide whether to output warning signal to sound and light warning device 3; Sound and light warning device 3 sends sound or light warning signal after receiving the warning signal from main processor 2, Sound and light warning signals can also be issued at the same time.

Embodiment 2

[0020] In this embodiment, the detection sensing device 1 is an acceleration sensor, and the acceleration sensor 1 detects the reduction value of the vehicle speed per unit time when the vehicle brakes and outputs a detection signal to the main processor 2, and the main processor 2 receives the signal. Judging whether the preset threshold is exceeded, and then deciding whether to output an alarm signal to the sound and light warning device 3; the sound and light warning device 3 sends out a sound or light warning signal after receiving the warning signal from the main processor 2, and can also send out sound and light at the same time warning sign.

Embodiment 3

[0022] In this embodiment, the detection sensing device 1 is a pressure sensor, the pressure sensor is connected with the automobile brake fluid pipe or the brake gas pipe, and outputs the detection signal to the main processor 2 according to the detected pressure value of the automobile brake pipe. signal, the main processor 2 judges whether it exceeds the preset threshold after receiving the signal, and then decides whether to output an alarm signal to the sound and light alarm device 3; the sound and light alarm device 3 sends out a sound or The light warning signal can also send out the sound and light warning signal at the same time.

[0023] The acousto-optic warning device 3 of the present invention includes a loudspeaker that sends out an emergency brake prompt sound and a brake light that sends out an emergency brake prompt, such as car horns and double-jump lights that are all provided in existing automobiles. As a better implementation mode, the sound and light warn...

Abstract

The invention relates to an active alarming and rear-end collision preventing device of a car, comprising a detecting and sensing device, a main processor and an acousto-optical alarm device which are electrically connected in sequence, wherein the detecting and sensing device is used for outputting a detecting signal to the main processor; the main processor is used for receiving an output signal from the detecting and sensing device and judging whether the output signal exceeds a preset threshold value so as to determine whether to output an alarm signal to the acousto-optical alarm device; the acousto-optical alarm device is used for synchronously sending an acousto-optical alarm signal after receiving the alarm signal from the main processor; and the detecting and sensing device comprises a displacement sensor, a pressure sensor or an acceleration sensor. Compared with the prior art, the active alarming and rear-end collision preventing device of the car has the advantages that the detecting and sensing device collects acceleration data when the car brakes or the displacement data of a brake pedal or the pressure data of a brake medium so as to accurately judge whether emergency brake of the car happens, and the acousto-optical alarm signal is sent at the first time to remind a driver of a rear car to pay more attention so that rear-end collision accidents are reduced.

Description

technical field [0001] The invention relates to the technical field of automobile safety, in particular to an active warning safety device for preventing automobile rear-end collision accidents. Background technique [0002] As automobiles enter people's daily life in large numbers, automobile driving safety has received more and more attention and attention. As far as common rear-end collision accidents are concerned, most of them are caused by the fact that after the vehicle in front brakes suddenly, the vehicle behind fails to know in time whether the vehicle in front brakes urgently or lightly steps on the brakes, resulting in insufficient braking force and failure to stop in time within a limited time and distance. cause a rear-end collision. In order to effectively avoid and reduce the occurrence of automobile rear-end collision accidents, the prior art is generally to install active detection radar on automobiles, and when the distance between the two vehicles is les...
