Hybrid power transient state measurement control test system

Abstract

The invention discloses a hybrid power transient state measurement control test system. The system comprises a test room, a large bottom plate and an electric dynamometer; the large bottom plate is arranged at the bottom of the test room; a shock absorber is arranged between the test room and the large bottom plate; the electric dynamometer, an analog electronic throttle, an analog turbocharged intercooler and a hybrid power installation bracket are arranged on the large bottom plate; hybrid power is arranged on the hybrid power installation bracket; the installation bracket is provided with an adjustment screw rod; the adjustment screw rod is fixed on an adjustment seat through an adjustment frame; a shaft coupling, a torque sensor, an elastic shaft coupling and a transmission shaft are sequentially connected with the right end of the electric dynamometer; and a test system is arranged on one side of the large bottom plate. The hybrid power transient state measurement control test system has the advantages that an overall hybrid power vehicle serves as a control target, the verification of relative properties, such as the dynamic property, the emission performance and the economical efficiency of the power assembly of a passenger vehicle and a commercial vehicle are realized, and the verification of an overall vehicle strategy related to the power assembly and the verification test of related components can be performed.

Description

technical field [0001] The invention relates to a hybrid power transient measurement control test system. Background technique [0002] At present, the domestic powertrain test bench can only carry out some endurance tests under fixed working conditions, and the system cannot meet the requirements of transient fuel consumption measurement, emission measurement, calibration of new energy hybrid power, simulation test, battery characteristic research and development of new energy hybrid power. At the same time, the bench test also needs to develop a dedicated controller for the bench, which will be very different from the real vehicle and cannot effectively reflect the actual operating state of the powertrain. [0003] Therefore, in order to solve the above problems, a new technical solution is provided. Contents of the invention [0004] The purpose of the present invention is to provide a hybrid power transient measurement control test system. [0005] The technical sche...
