Abstract

The invention discloses a jack horse system of a parallel-type hybrid engine assembly, which can be used to detect twisting moment distribution condition of hybrid control unit HCU to a generator and an ISG motor executed by hybrid vehicle engine assembly in various operating modes. The technical proposal which is adopted is that the jack horse system of a parallel-type hybrid engine assembly comprises a dynamometer and a control system, wherein the input shaft of the dynamometer machine is connected with the output shaft of a measured hybrid engine assembly, and the control system controls the dynamometer machine and the hybrid engine assembly. The invention is characterized in that a torque sensor is connected between the generator and the ISG motor in the hybrid engine assembly. The distribution of HCU to twisting moment can be checked through the torque sensor and the dynamometer.

Description

technical field [0001] The invention belongs to the automobile test technology, in particular to a bench and a bench system of a parallel hybrid power assembly. Background technique [0002] Since the 1990s, major automobile companies in Japan, the United States, and Europe have begun to develop hybrid vehicles. Since Japan's Toyota first launched a hybrid car in 1997, major car companies including Honda, General Motors, Ford, D-C and French Citroen have launched or developed products or concept prototypes. Experts believe that in the next ten years, 40% of cars may use hybrid technology. Since a hybrid vehicle includes at least two coupled power sources and has a variety of different operating modes, in a traditional vehicle, because there is only one engine as a power source, it does not involve the power distribution of multiple energy sources. In hybrid vehicles, an electric drive line is added. Due to the particularity of the hybrid multi-energy assembly test, the pr...
