Problems solved by technology
[0004] It can be seen that the current vehicle automatic driving strategy has the following technical problems: ignoring the road conditions of the adjacent lanes of the vehicle's current driving lane, obstacles in the adjacent lanes may also affect the vehicle
In addition, as the speed of the vehicle increases, the probability that the obstacles in the adjacent lanes will cause harm to the vehicle increases. Therefore, the vehicle speed and safety are inversely proportional to each other. The current automatic driving strategy of the vehicle is difficult to balance the vehicle speed and safety.

The embodiment of the present invention relates to a method and device for controlling the speed of an automatic driving vehicle, an on-board device, and a storage medium. The method includes: obtaining the driving speed of the vehicle and the speed limit of the lane; determining the obstacle detection range based on the driving speed and the speed limit of the lane; Detect obstacles within the obstacle detection range; control the vehicle speed based on the detection results. The embodiment of the present invention dynamically adjusts the obstacle detection range based on the driving speed and the speed limit of the lane, takes into account the adjacent road conditions of the vehicle's current driving lane, and then dynamically controls the vehicle speed based on the obstacle detection result, which can take both vehicle speed and safety into consideration.
Description
technical field [0001] Embodiments of the present invention relate to the technical field of machine vision, and in particular to a method, device, vehicle-mounted equipment, and storage medium for controlling the speed of an automatic driving vehicle. Background technique [0002] With the rapid development of vehicle autonomous driving technology, the requirements for the perception of the surrounding environment of the vehicle are getting higher and higher. Obstacle detection in the driving area based on perception results and automatic driving strategy planning after detecting obstacles are important links in the process of vehicle automatic driving. The execution effect of this link directly affects the driving ability (including speed and comfort) and safety of the vehicle. [0003] At present, the vehicle's automatic driving strategy is: set the driving speed according to the road, and perform straight-line detection on the lane where the vehicle is located, and plan...
