AI Technical Summary
Technical Problem
At urban road intersections, especially when there are no clear guide lines in the left-turn lane, autonomous vehicles cannot accurately enter the left-turn waiting area, resulting in an uncomfortable driving experience.
Method used
Based on target information, it is determined whether a vehicle needs to turn. If there is no lane line for waiting to turn, a virtual lane line is generated. The vehicle turns using a preset strategy, and lateral and longitudinal control is performed in combination with traffic light status and traffic flow speed.
Benefits of technology
It improves the comfort of intelligent driving, enhances the driver's experience, and ensures that vehicles can make left turns safely and smoothly in the absence of clear guide lines.

Abstract
This application discloses a vehicle control method, device, equipment, and medium, relating to the field of autonomous driving technology. The method includes: determining whether a vehicle needs to turn based on target information; if a turn is needed, detecting whether there is a corresponding waiting-turn lane line in the current lane where the vehicle is located; if not, generating a virtual waiting-turn lane line for the current lane based on a preset strategy, and controlling the vehicle to turn based on the virtual waiting-turn lane line; if a turn is needed, controlling the vehicle to turn based on the waiting-turn lane line. This application can generate a virtual waiting-turn lane line according to a preset strategy when the vehicle needs to turn and there is no corresponding waiting-turn lane line in the current lane, allowing the vehicle to perform turning control, thereby improving the comfort of intelligent driving and enhancing the driver's experience.
