Embodiment

[0031] Such as figure 2 The control component to be tested is shown as a battery management system 9. The battery management system 9 is composed of a single-chip circuit board and a corresponding peripheral I / O interface circuit. The battery management system 9 receives the battery information sent from the MATLAB / Simulink simulation model, including the cell voltage. , battery temperature, battery overall voltage, battery overall current and insulation resistance, after the processing and calculation of the battery management system 9 single-chip circuit, the state of charge SOC, battery health state SOH and the collected parameters related to the battery state are returned to the Model.

[0032] Simulink model 10 uses the vehicle model without the battery management system, and adds the data acquisition interface driver module that comes with the model library. If there is no driver module corresponding to the data acquisition board or CAN card in the model library, you ca...

Abstract

The invention discloses a hardware-in-loop simulation testing system for an automobile, and the system comprises an industrial control computer, a to-be-tested controller part, a data collection card of a PCI bus type, a CAN card of a PCI interface, and a signal conditioning circuit. The industrial control computer is provided with a MATLAB / Simulink software platform and a Labview software and Teststand software platform. The industrial control computer communicates with the to-be-tested controller part through the data collection card and the CAN card. The testing system occupies fewer resources, is low in cost, is simple in configuration, and is convenient and practical. One industrial control computer not only can achieve a function of real-time simulation of a target machine, but also can achieve a function of controlling and checking of a monitoring interface of an upper computer. The testing system achieves on-line adjusting of parameters and data recording. A testing method is high in speed of operation and is wide in range of application, and a driver with various types of data collection cards can be supplied to a user.

Description

technical field [0001] The invention relates to a hardware-in-the-loop simulation test device, more specifically, an experimental system applied to the development process of each control component of an electric vehicle, which is used to shorten product development time and reduce manpower and capital investment in vehicle hardware-in-the-loop simulation test system. Background technique [0002] With the increasing investment in research and development of electric vehicles by major domestic and foreign automobile manufacturers and the relevant support policies of the Chinese government, the popularity of electric vehicles is just around the corner. The control components of electric vehicles are a key technology of electric vehicles, and in the process of each control component, it is necessary to test the control components, and the requirements for testing are becoming more and more urgent. However, the development and testing of traditional control components can only...
