Abstract

The invention relates to a system for warning a rear vehicle due to emergency stop on a highway, which comprises an emergency stop vehicle, a danger alarm flashing light and a navigation and positioning system on the stop vehicle, a first ECU electrically connected with the danger alarm flashing light and the navigation and positioning system, a first wireless transceiver module electrically connected with the first ECU, a second wireless transceiver module wirelessly connected with the first wireless transceiver module, a regional network electrically connected with the second wireless transceiver module and a rear vehicle located behind the stop vehicle, wherein the rear vehicle is provided with a third wireless transceiver module wirelessly connected with the second wireless transceivermodule, a second ECU electrically connected with the third wireless transceiver module, and a vehicle sound output device electrically connected with the second ECU. A driver does not need to risk setting a warning sign, the safety of all rear vehicles can also be ensured, early warning is achieved, the alarm efficiency is high, the safety factor is large, and the method and the system can adaptto various environments and are not affected by climate changes.

Description

technical field [0001] The invention relates to the field of driving safety, in particular to a method and system for emergency parking on expressways to warn vehicles behind. Background technique [0002] With the development of the automobile industry and the rapid construction of expressways, road and driving safety issues have become increasingly prominent. Although some detection devices related to driving safety have been installed in individual areas, it is far from being able to solve the possibility that vehicles need to stop at any time due to sudden failures or emergencies. More vehicles in the rear get the information as early as possible, and should take early avoidance measures to ensure driving safety. [0003] The problem exposed now is: when a vehicle breaks down on the expressway or needs to stop urgently due to an emergency, not only must the warning lights be turned on, but also warning signs need to be placed at a certain distance, and placing signs man...
