The invention relates to a control method for a vehicle electric sliding door module, which brings about more convenient and reliable control on the electric sliding door module. The technical proposal is as follows: the control method for the vehicle electric sliding door module is characterized in that a vehicle body controller and the electric sliding door module are communicated with each other through an LIN bus so as to realize the control on the opening and closing of an electric sliding door. The vehicle body controller and the electric sliding door module are communicated with each other through the LIN bus, thereby effectively simplifying a line pencil, reducing the cost, and improving the efficiency and reliability of the communication.

The technical solution of this application proposes a UWB anchor point, calibration system, method and storage medium. The UWB anchor point calibration method includes: obtaining the level state of the pin of the UWB anchor point, and according to the level state of the pin of the UWB anchor point, As well as the preset corresponding relationship between the level state of the pin of the UWB anchor and the position of the UWB anchor, the position of the UWB anchor is determined and output. This technical solution can realize the self-identification position of the UWB anchor point through the pin state, and use the pin state of the UWB anchor point itself, without the need to develop multiple anchor points, save material control costs, and do not need to re-calibrate the vehicle off the assembly line. Compared with the existing technology , simplifies the wiring harness of the whole vehicle, saves the wire required for the anchor point, does not need to introduce signals from the main control or other modules for judgment, simplifies the circuit structure of the UWB anchor point, and reduces the cost of the entire vehicle.
