Method for monitoring driving state of based on vehicle road cooperation technology

Abstract

The invention discloses a method for monitoring a driving state of a vehicle based on a vehicle road cooperation technology, which is realized by an LTE-V technology based on roadside units provided on road sides and an onboard unit provided on a vehicle. Multiple groups of roadside units are arranged along the road, and the two groups of roadside units can communicate with each other; the communication ranges of adjacent two groups of roadside units have an overlapped range; and each group of roadside units communicate with the onboard unit in real time through the LTE-V technology. When thevehicle enters the roadside unit monitoring range, the roadside units communicate with the onboard unit in real time, the vehicle position information at different times is calculated, the velocity acceleration information at different times is acquired after calculation, thereby forming vehicle driving state information including the vehicle position, the speed, the acceleration, the time, a driving trajectory. The invention has the advantages that in the process of monitoring the vehicle driving state information, the method can completely avoid the satellite positioning system, and is basedon the vehicle road cooperation technology, and the real-time and reliability are stronger.

Description

technical field [0001] The invention relates to a method for monitoring the running state of a vehicle based on vehicle-road coordination technology, and belongs to the technical field of automotive electronics and intelligent control. Background technique [0002] Vehicle intelligent systems (such as ADAS) and automatic driving systems are all based on understanding the current driving state of the vehicle as the premise of control. By comparing the current driving state of the vehicle with the target state, it is judged whether it is necessary to take corresponding measures to control the vehicle and ensure The stability of the vehicle improves driving safety. The position information of the vehicle in all directions and the vehicle speed, acceleration and other information during the driving process of the vehicle can describe the driving state of the vehicle. [0003] At present, the satellite positioning system is usually used to obtain the position information of the ...
