Abstract

The invention provides a test system of a hybrid electric vehicle, which belongs to the technical field of automobile electronics. The test system overcomes the defects of more test personnel, large data acquisition workload, complex operation, large measurement error and the like in the existing method adopting manual monitoring and testing. The test system of the hybrid electric vehicle comprises a CAN bus and a PC machine, wherein the CAN bus is provided with a plurality of nodes; the PC machine is connected with the CAN bus; the PC machine comprises a central processing unit, and a message resolving module, a memorizer and a display which are connected with the central processing unit; a data acquisition module is connected between the CAN bus and the message resolving module; and the data acquisition module is used for acquiring information of each node from the CAN bus and displaying the information on the display after the resolution by the message resolving module. The test system of the hybrid electric vehicle can accelerate research and development, can quickly detect the state and display the fault, and has the advantages of high speed, low electromagnetic radiation, anti-electromagnetic interference, cost saving and the like.

Description

technical field [0001] The invention belongs to the technical field of automobile electronics, and relates to a test system of a hybrid electric vehicle. Background technique [0002] It is the development trend of automobile electronic technology to control the automobile through the automobile bus. The automobile bus network is applied to the control system, information system, driving system and sensor execution system of the whole vehicle to complete the communication and action of various sensors, controllers and actuators of the car, and realize the distributed control of the electric control system of the whole vehicle . [0003] When developing a hybrid vehicle, it is necessary to monitor and store some information of the hybrid vehicle (such as ISG motor, main drive motor, vehicle controller, battery, engine management system, liquid crystal display, etc.) Vehicle performance analysis, and can diagnose and calibrate the fault of hybrid vehicles. However, there is...
