The invention provides a driving control method and system for a vehicle at an intersection and a computer readable storage medium, and the method comprises the steps: obtaining an image of the intersection in front of the vehicle, inputting the image of the intersection in front into a trained neural network model, and carrying out the processing, obtaining a travelable path of a vehicle at an intersection and a transverse turning angle of the vehicle at a track point on the travelable path, receiving a path guiding signal, determining a final traveling path from the travelable path according to the path guiding signal, obtaining a transverse turning angle at a track point on the final travelable path, and generating a control instruction according to the final driving path and the transverse turning angle at the track point on the final driving path, sending the control instruction to a vehicle execution mechanism, and controlling the execution mechanism to execute the control instruction. According to the method, a new scheme is provided for advanced automatic driving in a complex environment, and the cost is greatly reduced compared with a scheme for performing path planning and trajectory prediction by using a high-precision map.
Description
technical field [0001] The present invention relates to the technical field of vehicle driving control, in particular to a method, system and computer-readable storage medium for vehicle driving control at intersections. Background technique [0002] At present, the trajectory prediction method collects the historical trajectory points of the vehicle, and predicts the future trajectory points of the vehicle itself through the curve fitting method and the probability model. This method is mainly based on the historical trajectory points. It does not combine the actual intersection conditions and cannot handle forks. Practical application of multiple drivable trajectories at intersections. Contents of the invention [0003] The present invention provides a driving control method, system and computer-readable storage medium for a vehicle at an intersection, so as to solve the problem that in the prior art, there are many possible driving trajectories at a bifurcation intersec...
