Battery replacement vehicle guiding method, battery replacement equipment positioning method and related system

The invention discloses a battery swap vehicle guiding method, which is applied to a battery swap station, the battery swap station comprises a battery swap channel, and the method comprises the following steps: detecting a first position of a to-be-swapped vehicle in the length direction of the battery swap channel; according to the first position, the to-be-exchanged vehicle is guided to an exchange potential; a distance measuring sensor facing the battery changing position is arranged on the exit side of the battery changing channel and detects the position of the to-be-changed vehicle in real time, so that whether the to-be-changed vehicle reaches the first position or not is judged according to the real-time position of the to-be-changed vehicle, and the to-be-changed vehicle is guided to continue to run, decelerate or brake. The position of the to-be-replaced vehicle can be detected in real time through the distance measuring sensor, so that the to-be-replaced vehicle is guided according to the relation
