1. A deciding system for moving a vehicle on a virtual rail, which is configured to decide a moving trajectory of the vehicle on a road, and the deciding system for moving the vehicle on the virtual rail comprising:
a positioning module, comprising:
a wireless tag device configured to generate a tag message; and
a magnetic device configured to generate a magnetic sensing message;
a vehicle dynamic detecting module disposed on the vehicle and configured to generate a vehicle dynamic message corresponding to the vehicle; and
a calculating-deciding module disposed on the vehicle and signally connected to the positioning module and the vehicle dynamic detecting module, wherein the calculating-deciding module receives the magnetic sensing message, the tag message and the vehicle dynamic message, and 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;
wherein the magnetic device comprises:
a plurality of magnetic nails disposed on the road and spaced apart from each other, wherein the magnetic nails transmit a plurality of magnetic signals; and
a magnetic rod disposed on the vehicle and receiving one of the magnetic signals to generate the magnetic sensing message;
wherein in response to determining that the vehicle passes through one of the magnetic nails, the magnetic rod senses the one of the magnetic nails to generate the magnetic sensing message corresponding to the one of the magnetic nails, thereby enabling the calculating-deciding module to calculate the deviation value between the magnetic sensing message and the vehicle dynamic message;
wherein the deviation value is smaller than or equal to a predetermined deviation threshold value, and a magnetic nail space between adjacent two of the magnetic nails is determined according to the deviation value.
