Vehicle safety system and method for preventing chain accidents after collision on highway

Abstract

The invention discloses a vehicle safety system and method for preventing a chain accident from happening after collision on a highway. The system is composed of a visual perception module, a vehicle-mounted computing module, an external communication system, a vehicle-mounted communication module, a network connection communication module, a vehicle control module and a trigger signal generationmodule. The method specifically comprises the following steps: when detecting that a vehicle is collided, triggering a vehicle safety system to work enabling a visual perception module to collect sensor information, judge whether passengers in the vehicle need rescue or not and whether the driving environment is safe or not; taking corresponding measures and re-planning a driving path and an action; checking the device state of the vehicle, judging whether the vehicle meets the self-starting condition or not, transmitting the moving track and the state information of the vehicle to a rear coming vehicle through the network connection communication module, taking corresponding measures according to information feedback of the rear coming vehicle so that vehicle chain accidents are effectively avoided, and the problem that in the prior art, functions of a chain collision prevention system are not perfect is solved.

Description

technical field [0001] The invention belongs to the technical field of intelligent networked vehicles, and relates to a vehicle safety system and method for preventing serial accidents after collisions on expressways. Background technique [0002] At present, in daily traffic accidents, after the first traffic accident of the vehicle, due to the distraction of the driver coming from behind and the untimely action, etc., serial accidents often occur. This phenomenon occurs in snowy days. It is more common on the highway in heavy rain. Therefore, it is necessary to provide a system and method for preventing serial accidents after vehicle collisions, so as to avoid injuries caused by serial accidents. [0003] The patent application number is 201811516814.5 "Method for Preventing Secondary Accidents After Vehicle Collision". This method determines the direction of the collision through the collision signal generated by the collision sensing device. Travel in the direction opp...
