Embodiment Construction

[0057] In order to make the purpose, technical solution and advantages of this specification clearer, the technical solution of this specification will be clearly and completely described below in conjunction with specific embodiments of this specification and corresponding drawings. Apparently, the described embodiments are only some of the embodiments in this specification, not all of them. Based on the embodiments in this specification, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of this specification.

[0058] In the prior art, when there are no other vehicles and obstacles around, the driverless device usually controls itself to drive at a higher speed along the driving path, but there are uneven roads (such as speed bumps) on the driving path. , potholes), if the unmanned driving equipment is driving at a higher speed, the undulations of the uneven road will be transmitted to the unmanne...

Abstract

The invention discloses a speed control method and device for unmanned equipment, which can be applied to the unmanned equipment in the unmanned field, such as an unmanned vehicle. The method comprises the steps: determining a stable passing speed corresponding to an uneven road surface according to the cargo integrity after the cargo loaded by test equipment passes through the uneven road surface; when the driving path of the unmanned equipment has an uneven road surface, determining nursing between the unmanned equipment and the uneven road surface, so as to determine a motion strategy of the unmanned equipment according to the current speed, the stable passing speed and the distance between the unmanned equipment and the uneven road surface, and according to the motion strategy, controlling the unmanned equipment to pass through the uneven road surface at the stable passing speed. According to the motion strategy of the unmanned equipment determined by the method, the influence of an uneven road surface area on the integrity of an object loaded by the unmanned equipment in the driving process is considered, and the completeness of a distribution task is ensured.

Description

technical field [0001] This specification relates to the field of unmanned driving technology, in particular to a speed control method and device for unmanned driving equipment. Background technique [0002] At present, with the development of unmanned driving technology, the use of unmanned equipment is becoming more and more extensive. In order to ensure the driving safety of the unmanned equipment, after the driving route of the unmanned equipment is determined, it is usually necessary to plan and control the speed of the unmanned equipment. [0003] In the prior art, a common speed control method for unmanned equipment is implemented based on the driving route of the unmanned equipment. Specifically, the unmanned equipment can perceive the surrounding environment through multiple sensors, determine the position of obstacles around the unmanned equipment, and then The driving route determines the movement strategy of the unmanned equipment at the next moment. [0004] ...
