The invention discloses a comprehensive transmission device ECU in-loop simulation test platform which comprises a comprehensive transmission device electro-hydraulic system semi-real-installation hardware subsystem, an interface module and an upper computer software simulation test subsystem, and a comprehensive transmission device electro-hydraulic system semi-real-installation hardware unit is connected with the upper computer software simulation test subsystem through the interface module. The simulation test is carried out on the comprehensive transmission device so as to carry out simulation calibration on the constructed engine model and transmission model, the accuracy in the simulation process of the engine output torque and the rotating speed of the gearbox output shaft is improved, the potential danger under the actual installation test extreme working condition is reduced, the convenience of the simulation test is improved, and the test efficiency is improved. The workload of developers is reduced, the testing process is simplified, the cost of simulation testing of the integrated transmission device ECU is reduced, and the safety of the gearbox in the training process is improved.
Description
technical field [0001] The invention belongs to the technical field of comprehensive transmission device ECU testing, and relates to a comprehensive transmission device ECU-in-the-loop simulation test platform. Background technique [0002] The integrated transmission ECU is the electronic control board of the gearbox. The function of the gearbox is to change the transmission ratio and expand the variation range of the torque and speed of the driving wheel; under the condition that the rotation direction of the engine remains unchanged, the car can run backwards. It is a mechanism used to change the speed and torque from the engine, and can change the transmission ratio of the output shaft and the input shaft in a fixed or divided gear. In the process of gearbox development and logic function verification, using the actual gearbox for testing increases the test cost, and easily damages the gearbox equipment, increases the development cycle, and increases the workload of deve...
