Publication number: 20230176580Abstract: The present invention is a vehicle positioning system and a vehicle positioning method for a container yard. The system includes a cloud server and a gate checking device. The gate checking device is communicatively connected to the cloud server, and senses a first vehicle to generate a first gate sensing signal and a second gate sensing signal. The cloud server receives and fuses the first gate sensing signal and the second gate sensing signal to generate first vehicle identity information and first vehicle positioning information. Since the present invention generates the first vehicle identity information and the first vehicle positioning information by fusing at least two sensing signals, the present invention can improve positioning accuracy and reliability by adopting a positioning technology combining multiple factors. Further, there is no need to install a transmitter or a receiver on the vehicle, improving a success rate to install the present invention.Type: ApplicationFiled: November 24, 2021Publication date: June 8, 2023Inventors: Mao-Chi Huang, Yung-Chih LIU, Chih-Hsiang Ho
