Method, apparatus and storage medium for durability testing of clutches in vehicles
By acquiring characteristic operating condition information of the clutch and simulating the road load of the whole vehicle, a test bench was built, and the clutch engagement and disengagement were controlled. This solved the problem that the existing technology could not accurately simulate the durability test of the vehicle under actual road conditions, and achieved a more accurate durability assessment.

Abstract
The application discloses a kind of durability test method, device and storage medium of clutch in vehicle.Therein, the method comprises: obtaining the characteristic working condition information of clutch in vehicle, wherein the characteristic working condition information is used to characterize the characteristic working condition of clutch;In response to the difference between the driving motor speed in characteristic working condition information and the generator speed in characteristic working condition information within the speed threshold range, control clutch to combine;In response to the duration of clutch combination is greater than the first duration threshold, and the clutch torque in characteristic working condition information is less than the torque threshold, control clutch to separate;In response to the duration of clutch separation is greater than the second duration threshold, based on the material properties of separated clutch, determine the durability test result of clutch.The application solves the technical problem that the working condition of vehicle on actual road cannot be simulated when testing the durability of clutch.
