| 发明名称 | Method of determining a position of a vehicle on a guideway | ||
| 摘要 | A method of determining a position of a vehicle on a guideway includes detecting a position of the vehicle relative to a first reflective positioning element along the guideway. The method also includes detecting a unique identification code of a transponder along the guideway, wherein the transponder is located a first known distance along the guideway from the first reflective positioning element. The method further includes determining the position of the vehicle, using a position determining system, based on a modulated reflection signal received from the transponder, a first non-modulated reflection signal received from the first reflective positioning element, and the first known distance. | ||

| 主权项 | 1. A method of determining a position of a vehicle on a guideway, the method comprising: receiving a first non-modulated reflection signal by a first antenna on-board the vehicle, the first non-modulated reflection signal being associated with a first reflective positioning element along the guideway; receiving the first non-modulated reflection signal by a second antenna on-board the vehicle; determining a difference between the first non-modulated signal received by the first antenna and the first non-modulated signal received by the second antenna; detecting a position of the vehicle relative to the first reflective positioning element along the guideway based on the difference between the first non-modulated signal received by the first antenna and the first non-modulated signal received by the second antenna; detecting a unique identification code of a transponder along the guideway, wherein the transponder is located a first known distance along the guideway from the first reflective positioning element; and determining the position of the vehicle on the guideway, using a position determining system, based on a modulated reflection signal received from the transponder, the position of the vehicle relative to the first reflective positioning element, and the first known distance. | ||
