Abstract

The invention discloses a method and device for determining a vehicle preview point and electronic equipment. The method comprises the following steps: acquiring a target trajectory point in an expected trajectory path of a target vehicle; attribute information of the target trajectory point is determined, and the attribute information at least comprises expected curvature information and expected orientation information; acquiring the current driving speed of the target vehicle; determining an elliptical trajectory path of the target vehicle according to the attribute information and the current driving speed; and determining a preview point of the target vehicle based on the elliptical trajectory path and the expected trajectory path. According to the invention, the technical problems of low preview point selection accuracy and poor automatic driving performance of a vehicle preview point determination method in the prior art are solved.

Description

technical field [0001] The present invention relates to the technical field of automatic driving, and in particular, to a method, a device and an electronic device for determining a preview point of a vehicle. Background technique [0002] In the field of autonomous driving technology, the control of the self-driving car is the last link of the system, and it is also the most important link. The quality of the self-driving car control effect directly affects the normal operation of the entire automatic driving system. The lateral control of the automatic driving control module mostly adopts the preview method, that is, the preview point of the vehicle is determined. However, in the method for determining the preview point of the vehicle in the prior art, a single factor is considered when determining the preview point, which leads to a low accuracy of the selection of the preview point, and further results in poor automatic driving performance. [0003] In view of the probl...
