Embodiment Construction

[0028] The present invention will be further described in detail below in conjunction with the accompanying drawings, so that those skilled in the art can implement it with reference to the description.

[0029] Such as figure 1 As shown, the PHEV bench system of the present invention includes a dynamometer control system, a power analyzer, and a main control computer. Among them, the control software of the dynamometer control system can pre-load the set working condition files. The dynamometer control system sends the working condition curve to the main control computer through the CAN bus. Curve, corresponding acceleration, deceleration or braking operation, in order to achieve the purpose of simulating working condition test. The main control computer has the function of rapid test, can carry out vehicle tests of different structures, has abundant I / O interfaces and external communication functions, and has high reliability and strong versatility. The power analyzer is u...

Abstract

The invention discloses a plug-in hybrid electric vehicle (PHEV) rack system. The PHEV rack system comprises a power measuring machine control system, a power analyzer and a main control computer andfurther comprises a fuel consumption meter, an emission analyzer and a power measuring unit. The power analyzer collects voltage data and current data through a voltage sensor and a current sensor andtransmits the direct voltage data, the direct current data, the alternating voltage data, the alternating current data and power data to the power measuring machine control system. The PHEV rack system further comprises an accelerator pedal and a brake pedal which are connected into a vehicle controller. The vehicle controller, a driving motor controller, an engine controller and an electric generator controller are connected through a CAN bus and connected to an OBD diagnosis interface. The OBD diagnosis interface is connected with the power measuring machine control system through a communication line and the main control computer.

Description

technical field [0001] The present invention relates to a stand system, in particular to a PHEV (Plug-inhybrid electric vehicle, PHEV for short, ie plug-in hybrid electric vehicle) stand system. Background technique [0002] In the process of research and development of hybrid electric vehicles, many technical problems need to be solved, such as the matching of vehicle parameters and transmission system parameters, control strategy design and optimization, dynamic switching process, shift control process, energy management strategy, etc. [0003] To verify these technical issues, a real test environment is required, and a supporting bench system is required to simulate the environment of the entire vehicle, test the characteristics of the motor, engine, battery, etc., and also test the performance of the entire vehicle, simulate working conditions, and verification strategies, etc., but the traditional The benches are all single assembly tests, the test cycle is long, and th...
