The invention relates to a guide method for a vehicle guide system of an electric vehicle charging and replacing station. The guide system comprises a monitor center, one or more vehicle terminals, and one or more ground marks, wherein the monitor center comprises a monitor server; the vehicle terminal comprises a central control processing unit, which is respectively connected with an RFID (radio frequency identification) module, an image acquisition module, a video encoding module, a vehicle data acquisition module, a vehicle control module, a display module, a GPS (global positioning system) module, a wireless communication module (II), a power supply module, and a storage module; and the ground mark comprises an image mark line and an RFID mark. The guide method comprises the following steps: (1) vehicle information reading and processing; (2) path planning, and map information returning; (3) visual navigation; (4) IRID location charging and battery replacing. By adopting image mark navigation and RFID mark location, the method can guide electric vehicle to park at charging position or replacing position rapidly and accurately, thereby providing guarantee for stable operation of the electric vehicle charging and replacing station.
