Problems solved by technology

The fluctuation of the center point of the obstacle will lead to the deviation of the predicted trajectory and speed of the obstacle
These deviations can sometimes affect the normal operation of self-driving vehicles

Abstract

The embodiment of the invention discloses a method and device for controlling a vehicle. A specific mode of execution of the method comprises the following steps of identifying a point cloud of an obstacle from the point clouds collected during vehicle travelling; determining the center point of the point cloud aiming at the obstacle and collected at least one collection moment at current collection moment and before the current collection moment; calculating the variance of at least two determined center points on the X-axis; determining whether the variance is smaller than a preset fluctuation threshold; and in response to determining that the variance is smaller than the fluctuation threshold, controlling the vehicle to continue to travel according to the current travelling speed, and correcting the coordinate value of the X-axis of the center point of the point cloud, collected at the current collection moment, of the obstacle. The mode of execution reduces the influence on the normal travelling of the autonomous travelling vehicle due to the change of the state of the obstacle.

Description

technical field [0001] The embodiments of the present disclosure relate to the field of computer technology, and in particular to a method and device for controlling a vehicle. Background technique [0002] In the application scenario of automatic driving, lidar can be used to perceive obstacles on the road. When detecting and identifying obstacles based on the point cloud acquired by lidar, the center point of the point cloud is usually used as the center point of the obstacle, so as to analyze the trajectory and speed of the obstacle. In practical applications, since the posture of soft obstacles such as pedestrians and animals will change during the movement process, such as sideways, turning around, and large swings of limbs, etc., the center point of the point cloud corresponding to such soft obstacles will change with time. Small fluctuations occur with changes in attitude. The fluctuation of the center point of the obstacle will lead to the deviation of the predicte...
