Description

technical field [0001] The invention relates to the field of automobile manufacturing, in particular to an intelligent load box, a vehicle start-stop simulation device and a method for simulating vehicle start-stop. Background technique [0002] Many electronic products usually need to be tested before they are officially put into production or on the market, such as the test of the vehicle start-stop controller. The test of the existing vehicle start-stop controller is mainly the physical test; the physical test requires the clutch sensor, the neutral sensor, etc., and the clutch sensor, neutral sensor, etc. used in the test of the vehicle start-stop process in the physical test belong to the mechanical cooperation to output the signal. Components, therefore need to be integrated in the mechanical structure in order to be tested. The mechanical structure assembly brings a lot of inconvenience to the test and hinders the effective conduct of the test. For example, it is tro...
