Document Type and Number:
WIPO Patent Application WO/2023/005742
Kind Code:
A1
Abstract:
Disclosed in the present application are a traveling trajectory control method and apparatus applied to an unmanned vehicle, and a device and a medium. The method comprises: determining target speed information of a target vehicle at the current target preview point; according to the target speed information, determining a target front-view distance corresponding to the target preview point; and according to the target front-view distance and wheelbase information, determining a front-wheel rotation angle of the target vehicle, so as to control the travel of the target vehicle on the basis of the front-wheel rotation angle, wherein the wheelbase information is the distance between a front axle and a rear axle of the target vehicle.
