Problems solved by technology

This patent application acquires the absolute position coordinates of vehicles in the earth coordinate system in the surrounding environment of the vehicle and the relative position coordinates of vehicles in each environment in the vehicle coordinate system, and obtains the positioning information of the vehicle through fusion. The defect is that the vehicle-to-vehicle communication environment Among them, there are many vehicles in the surrounding environment of the vehicle, and the amount of data processing is large. Although the positioning accuracy of the vehicle is improved, the processing efficiency is sacrificed.

Embodiment 1

[0041] Such as figure 1 As shown, this embodiment provides a sensory information compensation system based on vehicle-to-vehicle communication. The system includes car A and car B. The configurations of car A and car B are the same, and both are equipped with a main control module, a radar module, Machine vision module, communication module and GPS positioning module.

[0042] For car A and car B, the functions of each module are as follows:

[0043] The communication module includes a vehicle communication unit. The vehicle communication unit broadcasts the GPS position information of the vehicle to the network segment to which it belongs according to a preset period, and simultaneously receives the GPS position information broadcasted by other vehicles in the network segment to which it belongs. The communication module can be controlled by the main control module to establish a communication connection with other vehicles, and transmit sensing information after the communi...

Embodiment 2

[0067] Such as figure 2As shown, this embodiment provides a sensory information compensation system based on vehicle-to-vehicle communication. The system includes car A and car B, wherein car A is equipped with a main control module, a radar module, a machine vision module, a communication module and a GPS Positioning module, vehicle B is equipped with a communication module, a GPS positioning module and a main control module.

[0068] The difference from Embodiment 1 is that as long as the vehicle B in this embodiment is equipped with a GPS positioning module that obtains its own GPS position information, a communication module that broadcasts its own GPS position information and can establish a communication connection, it can receive this embodiment. The sensory information acquired by the car, and compensate the sensory information of car B.

Embodiment 3

[0070] The difference from Example 1 is that Car A and Car B obtain sensing information within the preset range at the same time and transmit it to each other for sensing information compensation. In this embodiment, Car A is driving through a blind bend, and Car B is in the blind bend area And it cannot be seen with A car, the specific steps are as follows:

[0071] Car A receives the GPS location information broadcast by car B, and car B also receives the GPS location information broadcast by car A;

[0072] Car A sends a communication connection request, and establishes a communication connection with car B by sending a request-response-response confirmation;

[0073] Car A confirms the rough position of car B according to the GPS position information of itself and car B, and forms a sensing compensation range based on this, and sends the sensing compensation range to car B;

[0074] Car A continuously monitors and uploads the radar information and road target image inform...

Abstract

The invention discloses a perceptual information compensation system and method based on vehicle-to-vehicle communication. Each vehicle in the system is provided with a communication module capable of broadcasting and data interaction; through the communication module, the vehicle broadcasts own GPS position information to surrounding vehicles and receives GPS position information broadcasted by other vehicles at the same time, The vehicle determines the relative position relation between other vehicles and the vehicle according to the GPS position information of the other vehicles to form a rough position range, a perception compensation range can be determined according to the rough position range, and then radar information and road image information in the perception compensation range are continuously obtained through radar and machine vision; the time and space fusion is carried out, and the accurate position of the target vehicle is obtained; the absolute position and the relative position of the target vehicle in the sensing range of the vehicle are obtained through coordinate conversion, the sensing information of the vehicle is compensated, and the sensing range and precision of the vehicle are increased.

Description

technical field [0001] The invention relates to the technical field of analysis and processing of in-vehicle perception data, in particular to a sensory information compensation system and method based on vehicle-to-vehicle communication. Background technique [0002] At present, as a new type of smart car, unmanned vehicles perceive road condition information through intelligent sensing systems, and then make independent planning and decision-making based on the perceived information to achieve automatic control and achieve the effect of unmanned driving. Since the line of sight is easily affected when the road traffic is congested, vehicle-road collaborative perception has become an important part of the safety driving assistance system of intelligent vehicles. , reduce the incidence of traffic accidents. [0003] In reality, due to the complex and changeable road condition information, there are many uncertain factors and emergencies, the accurate and comprehensive colle...
