Combined warning device and method for preventing rear-end collision of vehicle

Abstract

The invention discloses a combined warning device and method for preventing a rear-end collision of a vehicle. The device comprises a manual alarm button, a pressure sensor, a central processing unit,a sound alarm device, a smoke alarm device and a wireless alarm signal transceiver device, wherein the sound alarm device is mainly composed of an audio chip and a vehicle speaker; the smoke alarm device is mainly composed of an electromotor, an electric nozzle and a smoke agent tank; the wireless alarm signal transceiver device is mainly composed of an antenna, a signal processing module, an input amplification module and an output amplification module. The combined warning method for preventing the rear-end collision of the vehicle disclosed by the invention comprises two alarm start modes:one is that a driver presses the manual alarm button; the other is that when the vehicle collides, the pressure sensor automatically detects the collision pressure generated when the vehicle collides; when the collision pressure reaches a preset value as shown in the specification (N is the unit of force), the alarm is started. The combined warning device and method aim to quickly and effectivelyissue a warning to rear vehicles when the vehicle undergoes the rear-end collision or after the driver discovers a traffic accident on the road ahead, so that the rear vehicles can decelerate or stopas early as possible, thereby avoiding the serial rear-end collisions; and the combined warning device and method have high practical value and popularization value.

Description

technical field [0001] The invention relates to a combined early warning device and method for preventing automobile rear-end collision. The invention belongs to the technical field of automobile safety driving. Background technique [0002] With the improvement of the economic level and the rapid development of the automobile industry, the number of motor vehicles has continued to increase. Although this has brought a lot of convenience to people's travel, it has also led to an increase in traffic accidents year by year. In traffic accidents, rear-end collisions account for a large proportion, and rear-end collisions, especially serial rear-end collisions, can often cause great casualties and economic losses. Therefore, how to reduce and avoid the occurrence of rear-end collision accidents has very important significance. After a sudden situation such as a traffic accident or road surface collapse occurs on the road ahead, if the driver of the vehicle behind does not know...

AI Technical Summary

Problems solved by technology

This patent only uses the brake light to warn the rear car, and the driver of the rear car may mistakenly think that it is a normal deceleration, and cannot realize the major dangers such as traffic accidents or road landslides ahead, so that rear-end collisions or serial rear-end collisions cannot be avoided.

In the prior art, there is no device and method for preventing serial rear-end collisions of automobiles by combining sound alarm devices, smoke alarm devices, and wireless alarm signal transceivers, etc.
