Vehicle rear-end collision avoidance system and method

Abstract

The invention discloses a vehicle rear-end collision avoidance system and method and belongs to the field of vehicle communication. The vehicle rear-end collision avoidance system comprises an onboarddevice and a cloud server. The onboard device comprises a processor for determining vehicle operating state information and a vehicle fire situation; a three-axis acceleration sensor electrically connected to the processor and used for detecting and generating the vehicle operating state information; a smoke sensor for detecting and generating vehicle fire situation information; an alarm for giving an alarm; a voice recognition module for a human-machine interaction in order that the processor confirms a state for a passenger after determination; a wireless communication module for connectingthe onboard device and the cloud server; and a positioning module for positioning the vehicle location information. The cloud server is configured to send the location information of an accident vehicle to surrounding vehicles and a traffic rescue department. The vehicle rear-end collision avoidance system and method not only can promptly give an early warning and prevent the rear-end collision,but also can prevent false warning.

Description

technical field [0001] The invention relates to the field of vehicle communication, in particular to a vehicle rear-end collision prevention system and a rear-end collision prevention method. Background technique [0002] With the rapid development of China's economy, the automobile industry has developed rapidly, and more and more people own their own cars. The ensuing traffic safety problems are becoming more and more prominent. Among the many traffic accidents in the past, secondary accidents and serial rear-end collisions caused the largest losses and the most extensive impacts. [0003] To prevent traffic accidents, in addition to the drivers themselves having to develop good driving habits, that is, "don't drive while drinking, and don't drive when fatigued", it is also necessary to prevent and avoid incidentally affecting more other vehicles due to accidents of other vehicles through multiple channels. Drivers and vehicles, causing major traffic accidents, causing ma...
