A deciding system for moving a vehicle on a virtual rail is configured to decide a moving trajectory of the vehicle on a road, and includes a positioning module, a vehicle dynamic detecting module and a calculating-deciding module. A wireless tag device is configured to generate a tag message. A magnetic device is configured to generate a magnetic sensing message. The vehicle dynamic detecting module is disposed on the vehicle and configured to generate a vehicle dynamic message corresponding to the vehicle. The calculating-deciding module is signally connected to the positioning module and the vehicle dynamic detecting module. The calculating-deciding module receives the magnetic sensing message, the tag message and the vehicle dynamic message. The calculating-deciding module calculates a deviation value between the magnetic sensing message and the vehicle dynamic message, and decides the moving trajectory of the vehicle according to the tag message and the deviation value.

A magnet-guiding switching system includes a lane magnetic field device, a switching controlling module and a route controlling center. As the switching controlling unit informs the magnetic field switching unit to turn on the first switching electromagnets and to turn off the second switching electromagnets according to the driving signal, the vehicle is guided by magnetic fields of the first switching electromagnets to drive from the first section of the first route to the second section along the guiding section; as the switching controlling unit informs the magnetic field switching unit to turn on the second switching electromagnets and to turn off the first switching electromagnets according to the driving signal, the vehicle is guided by magnetic fields of the second switching electromagnets to drive from the first section of the first route to the continuous section of the second route along the switching section.

The present invention discloses a self-calibration method for an electric power steering system, which can self-calibrate the sensors to a normalized state to prevent from signal distortion, whereby to maintain stable steering sense of the driver and promote robustness and performance of the EPS system. The self-calibration method includes a signal offset compensation tactic and a zero-point signal self-calibration tactic. The present invention determines whether to undertake self-calibration according to judgement tactics, including a sensor power supply judgement tactic, a sensor correctness judgement tactic, and a self-calibration triggering condition. The self-calibration method can increase the correctness of sensors, maintain the original steering-assisting function and promote robustness of the EPS system.
