Problems solved by technology

This kind of big data calculation and huge data transmission are limited by the network, which will cause information delay and cannot make the vehicle respond in real time
And, when the network fails, the whole system will be paralyzed
Therefore, at present, this method can only be used for security warnings and prompts

Abstract

The embodiment of the invention presents a driving planning method and device based on a road side unit, a road side unit and a storage medium. The method comprises the following steps: determining apre-selected path for a target vehicle according to the vehicle information of the target vehicle, wherein the target vehicle is a vehicle within the communication range of a road side unit; acquiringobstacle information corresponding to the pre-selected path according to the sensing data of sensors, and generating a dynamic map for the target vehicle according to the pre-selected path and the obstacle information; carrying out path planning and speed planning for the target vehicle according to the dynamic map to generate planned trajectory information; and determining the target trajectoryinformation of the target vehicle according to the planned trajectory information. According to the method in the embodiment of the invention, the path and speed of the target vehicle are planned based on the road side unit, and the information of obstacles such as pedestrians is considered in the planning process and added to the dynamic map, so that automatic driving of the target vehicle can berealized or driving decision service can be provided for the driver of the target vehicle.

Description

technical field [0001] The invention relates to the field of traffic technology, in particular to a roadside equipment-based driving planning method, device, roadside equipment and storage medium. Background technique [0002] At present, the vehicle-road coordination system mainly adopts the vehicle-to-everything (V2X) technology. In the automatic driving mode, the vehicle needs to rely on the cloud to analyze real-time traffic information and transmit it to the vehicle, and the vehicle automatically selects the driving route with the best road conditions. In the real world, traffic conditions are very complex and changeable. This method requires vehicles or the cloud to process and calculate based on a series of traffic information such as real-time traffic conditions, road information, and pedestrian information. This kind of big data calculation and huge data transmission are limited by the network, which will cause information delay and cannot make the vehicle respond ...
