Abstract

The embodiment of the invention discloses a speed control method and device, control equipment and a storage medium. The method comprises the following steps: determining a track intersection point between a motion track of dynamic obstacles on two sides of a vehicle driving direction and a driving track of the vehicle; predicting a first collision point with actual collision in the track intersection points; and controlling the running speed of the vehicle according to the vehicle and the collision part corresponding to the dynamic obstacle at the collision point. According to the method, the positions where the vehicle collides with the obstacles on the two sides are determined according to the predicted first actual collision point, the running speed of the vehicle is controlled accordingly, it can be guaranteed that collision can be predicted in time, the vehicle speed is flexibly controlled according to the collision positions, unnecessary speed changing or braking and other situations are avoided, and the safety of the vehicle is improved. And the reliability of vehicle speed control and the driving safety are effectively improved.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of driving control, and in particular, to a speed control method, device, control device, and storage medium. Background technique [0002] In recent years, autonomous driving technology has developed rapidly. In the application scenario of autonomous driving, the primary problem that needs to be solved is to reasonably control the speed of the vehicle so that it can drive stably in good road conditions, and be able to decelerate or decelerate in time in the presence of obstacles. Brake to avoid obstacles effectively. [0003] The current speed control method mainly maps all obstacles that intersect with the path planned by the main vehicle into a displacement-time (ST) diagram, and then performs speed planning in the ST diagram. [0004] In the process of implementing the present invention, it is found that there are at least the following technical problems in the prior art: the abov...
