Embodiment 1
[0032] The embodiment of the present invention can be applied to various unmanned vehicles, and the types of unmanned vehicles include but not limited to: park logistics vehicles, new energy vehicles, automobiles, and trucks. The body parameters and scannable information of each type of unmanned vehicle are different. When analyzing road signs, lane lines, signage and other vehicle information and obstacles, the parameters used are different. The specific situation can be adjusted by yourself.
[0033] On unmanned vehicles, it can be integrated: control platform, camera device, sensing equipment (including distance sensor, sensing equipment), safety warning device, etc.
[0034] According to an embodiment of the present invention, an embodiment of a control method for an unmanned vehicle is provided. It should be noted that the steps shown in the flow chart of the accompanying drawings can be executed in a computer system such as a set of computer-executable instructions, Als...

Abstract
The invention discloses a control method and device of an unmanned vehicle and the unmanned vehicle. The control method comprises the following steps: in a driving state, acquiring a target planned path to be driven by the unmanned vehicle in a next time period; constructing a simulation vehicle consistent with the vehicle body data of the unmanned vehicle; controlling the simulated vehicle to run on a target planning path in the path planning three-dimensional map so as to estimate whether the vehicle is collided or not, and obtaining a simulation result; based on the simulation result, adjusting a vehicle collision avoidance strategy, and the vehicle collision avoidance strategy is used for representing that the unmanned vehicle is prevented from colliding in the driving process. The technical problem that in the prior art, when an unmanned vehicle runs on a road, the vehicle speed cannot be adjusted in time, and vehicle collision accidents are likely to happen is solved.
Description
technical field [0001] The present invention relates to the technical field of vehicle control, in particular, to a control method and device for an unmanned vehicle, and an unmanned vehicle. Background technique [0002] In related technologies, with the continuous development of unmanned driving technology, a large number of applications have begun on urban standardized roads and logistics roads. The current unmanned driving technology is mostly aimed at the situation where there are many vehicles, and the road information of urban roads is relatively complete. When navigating and changing directions, it can provide more perceptual information to avoid collisions of unmanned vehicles. [0003] However, the current unmanned driving technology has a lot of disadvantages. The current unmanned vehicles only perform vehicle collision verification in an ideal environment before leaving the factory. In this ideal environment, the roads are relatively regular, and the driving spee...
