Embodiment Construction

[0023] The specific implementation manners of the present invention will be further described below in conjunction with the accompanying drawings, so as to make the technical solution of the present invention easier to understand and grasp.

[0024] Such as figure 1 As shown, a queue redundancy control system based on information fusion technology includes a V2X communication module, an environment perception module, a queue longitudinal redundancy controller, and a motion execution module. Communication between facilities and other components can be used to send and receive the driving status information of the target vehicle and other vehicles in the queue, such as displacement, speed and acceleration, etc. The V2X communication module sends the collected surrounding vehicles and their own motion information to the queue Longitudinal redundant controller; the environmental perception module uses the camera, laser radar, ultrasonic radar and other on-board sensors to perceive...

Abstract

The invention discloses a vehicle queue longitudinal redundancy control system based on information fusion technology, which comprises a queue longitudinal redundancy controller, a V2X communication module for transmitting the acquired motion information of surrounding vehicles and a host vehicle to the queue longitudinal redundancy controller, an environment sensing module for acquiring vehicle surrounding environment information by using an onboard sensor and transmitting the information to the queue longitudinal redundancy controller, and a motion execution module for receiving the vehicleenvironment information and the driving parameter information sent by the queue longitudinal redundancy controller. The vehicle queue longitudinal redundancy control system based on information fusiontechnology combines the V2X communication system and the onboard sensor environment awareness system for multi-source information fusion, and uses the queue longitudinal redundancy controller to realize switching of different control strategies to ensure stable and safe driving of a vehicle queue.

Description

technical field [0001] The invention specifically relates to a vehicle platoon longitudinal redundancy control system based on information fusion technology. Background technique [0002] Vehicle platooning is to form adjacent vehicles in a single lane, automatically adjust the longitudinal motion state of the vehicle according to the information of adjacent vehicles, and finally achieve a consistent driving speed and desired geometric configuration. By queuing vehicles, it can significantly alleviate traffic congestion, improve traffic efficiency, improve driving safety and energy efficiency. [0003] The traditional vehicle platoon uses on-board sensors to sense the environment, detect the motion state of adjacent vehicles and respond, among which, the most common is the information flow topology of the preceding vehicle - each vehicle in the queuing follows its own preceding vehicle. The car moves. With the development of communication technology, vehicle-to-other (V2X)...
