Problems solved by technology

[0002] With the continuous increase of the number of vehicles, the number of vehicles driving on the expressway increases, and independent vehicles need to maintain a safe inter-vehicle distance to ensure driving safety. As a result, the carrying capacity of the expressway is easy to reach saturation, and it is difficult to improve the traffic efficiency.
When driving in a team, because the driving routes of the vehicles in the team are consistent, the distance between vehicles can be shortened, which is conducive to improving driving efficiency. The current platoon driving system is based on radar and camera active sensors. Vehicles can only be arranged in a fixed location. Only one team can form a team, and the flexibility of team formation is poor
At the same time, the safety of vehicles exiting the queue in the active platoon driving system is poor, and the rear vehicle cannot predict the exit behavior of the vehicle in front, which has a greater possibility of rear-end collision

Abstract

The present invention discloses a cooperative-type queue driving system based on communication and a team forming and quitting method based on the same. Each vehicle in the queue is provided with onequeue driving system. The system comprises: a turn signal switch, a queue head vehicle application switch, a queue following vehicle application switch, a takeover queue head vehicle switch, a quitting queue head vehicle switch, a quitting queue following vehicle switch, a vehicle speed sensor, a yaw velocity sensor, an automatic driving vehicle speed and steering control module and an ECU calculation module which are connected with a CAN bus, the ECU calculation module obtains switching signals of queue driving, vehicle speeds and the yaw velocity signals from the CAN bus and sends the switching signals of queue driving, the vehicle speeds and the yaw velocity signals to the automatic driving vehicle speed and steering control module; a high-precision location model is employed to send the location information of the vehicles to the ECU calculation module, a wireless communication module is employed to receive and broadcast the queue driving information, and an HMI prompting module isemployed to display the queue state information. The driving safety of team forming and quitting is ensured.

Description

technical field [0001] The invention belongs to the technical field of vehicle driving control, and in particular relates to a communication-based cooperative platoon driving system and a team formation and withdrawal method based on the system. Background technique [0002] With the continuous increase of the number of vehicles, the number of vehicles driving on the expressway increases, and independent vehicles need to maintain a safe inter-vehicle distance to ensure driving safety. As a result, the carrying capacity of the expressway is easy to reach saturation, and it is difficult to improve the traffic efficiency. When driving in a team, because the driving routes of the vehicles in the team are consistent, the distance between vehicles can be shortened, which is conducive to improving driving efficiency. The current platoon driving system is based on radar and camera active sensors. Vehicles can only be arranged in a fixed location. Only one team can form a team, and t...
