The invention provides an automatic following method and device of a vehicle and the vehicle. The method comprises the following steps: determining a first moment when a first sound detection module detects a first sound signal directly reaching the first sound detection module from intelligent equipment, and determining a second moment when a second sound detection module detects a second sound signal directly reaching the second sound detection module from the intelligent equipment, wherein the first sound signal and the second sound signal are simultaneously emitted by intelligent equipment, and the first sound detection module and the second sound detection module are arranged in a vehicle; determining a time difference between the first moment and the second moment; determining a relative angle between the vehicle and the intelligent device based on the distance between the first sound detection module and the second sound detection module and the time difference; and controllingthe vehicle to follow the intelligent equipment based on the relative angle. Automatic following of the vehicle can be realized based on the relative angle.
Description
technical field [0001] The embodiments of the present invention relate to the technical field of vehicle control, and more specifically, relate to a method and device for automatically following a vehicle, and a vehicle. Background technique [0002] In recent years, with the continuous advancement of technology and the continuous exploration of smart life, people have more and more demands for the automatic follow function of smart devices, such as smart follow supermarket carts, smart follow suitcases, smart follow baby carriages, smart follow Balanced car, smart following car, etc. Intelligent following can reduce manpower input and improve work efficiency. [0003] The current automatic following methods mainly include vision-based technology and label-based technology. Vision-based technology is mainly equipped with a camera on the device to scan the object to be followed (such as a human leg), establish a 3D stereoscopic figure, and model it. Calculate and judge the ...
