Foldable automatic following electric vehicle

Abstract

The invention relates to a foldable automatic following electric vehicle. The electric vehicle includes an foldable electric vehicle body, at least two UWB positioning bases, a UWB positioning label and a controller, wherein the at least two UWB positioning bases are arranged on the foldable electric vehicle body, the UWB positioning label is arranged on a specific object, and the controller is arranged on the foldable electric vehicle body. The controller is connected with the UWB positioning bases, the UWB positioning bases is communicated with the UWB positioning label through a UWB signal,and the controller controls the foldable electric vehicle body to achieve automatic following of the specific object according to a received signals of the UWB positioning bases. Compared with the prior art, the electric vehicle has the advantages of being high in following accuracy and capable of relieving the burden of users in walking, and the electric vehicle has the following function and meanwhile can also retain a certain transportation and object loading capacity.

Description

technical field [0001] The invention belongs to the fields of UWB (Ultra-Wideband, ultra-wideband) positioning and mechanical design, and specifically designs a foldable electric vehicle based on UWB positioning and following technology. Background technique [0002] Along with the development of science and technology, electric vehicle has become people's daily necessities. The types of electric vehicles are becoming more and more abundant, and convenience and speed are the most typical characteristics of electric vehicles. With the emergence of more convenient and fast functions of electric vehicles, a foldable automatic following electric vehicle has become possible as a tool for daily needs in various fields. At present, the technical difficulties of the foldable self-following electric vehicle include the determination of the relative position between the electric vehicle and the target when moving; the electric vehicle retains the original driving function and certain...

Problems solved by technology

However, these traditional positioning methods have certain limitations. For example, the GPS signal decays seriously after being blocked by buildings, and the error is large, which is not suitable for small-scale high-precision positioning. In addition, although ultrasonic positioning technology has high positioning accuracy, it can be used for small Accurate range positioning, but ultrasonic waves are greatly affected by multipath effects, and at the same time require a large investment in underlying hardware facilities, the cost is too high
