Differential lock controller testing method and related device

The embodiment of the invention discloses a differential lock controller testing method. The method comprises the steps that an input and output model for a target differential lock controller is established on a testing platform; the input and output model comprises a plurality of model input interfaces and a plurality of model output interfaces; the signals of the multiple model input interfaces are matched with sending interface signals corresponding to the target differential lock controller, and the signals of the multiple model output interfaces are matched with receiving interface signals corresponding to the target differential lock controller; connecting the plurality of model input interfaces with a sending interface corresponding to the target differential lock controller; connecting the plurality of model output interfaces with a receiving interface corresponding to the target differential lock controller; and testing the target differential lock controller on the test platform.
