Embodiment Construction

[0016] The implementation scenario of this embodiment is formation driving: driving in a convoy, the first vehicle is the lead vehicle and has the right to accelerate and decelerate, and the subsequent vehicles are slave vehicles and have no independent control right, that is, they cannot perform acceleration and deceleration processing. The goal is to maintain a certain distance between all vehicles and drive synchronously to save fuel consumption of the vehicles.

[0017] Such as figure 1 As shown, the head car broadcasts the assigned data packet including the acceleration information of each slave car through the wireless channel; the slave car receives the assigned data packet through the wireless channel and parses out the corresponding acceleration information and controls the respective driving accordingly. At the same time, the slave car periodically updates the model parameters in the model information online, and sends the updated model information to the head car in...

Abstract

The invention discloses an unmanned motorcade control method based on vehicle state information. A first vehicle is a head vehicle and has acceleration and deceleration control right, and subsequent slave vehicles have no independent control right, that is, acceleration and deceleration processing cannot be carried out, and the head vehicle broadcasts an assignment data packet comprising acceleration control information of each slave vehicle backwards through a wireless channel; and the slave vehicles receive the assigned data packet through the wireless channel, analyze the respective corresponding acceleration information, control the respective driving states and periodically send the respective correction state information and model information to the head vehicle. The state information is estimated through the transmission model, and excessive estimation errors are avoided through the state information correction packet.

Description

technical field [0001] The invention relates to a technology in the field of unmanned driving, in particular to an unmanned fleet control method based on vehicle state information. Background technique [0002] The Internet of Vehicles will become an important part of the Internet of Things technology in the future. In the Internet of Vehicles scenario, vehicles frequently transmit state information, such as the vehicle's position, distance to the vehicle in front, and speed. This information will be used for car networking services, such as formation driving and so on. The Internet of Vehicles is a delay-sensitive network, because vehicles are high-speed mobile terminals, and safety is the first standard. Excessive delays in transmitting important vehicle status information are dangerous to safe driving. These status information will be sent and received through the wireless interface in the Internet of Vehicles. Wireless channels are shared by wireless devices. The mo...
