Embodiment Construction

[0019] A pure electric vehicle vehicle controller model in-loop testing method described in the embodiment of the present invention comprises the following steps:

[0020] 1) Configure the model under test: select the Simulink model of the VCU controller under test, including the VCU controller model itself and the corresponding parameter files (that is, configure the VCU version under test, configure the VCU parameters under test, configure the controlled electric vehicle parameters and test cases to be tested); the parameter file is the calibration data of the VCU controller, such as the proportional coefficient or integral coefficient of the proportional-integral controller, which should be consistent with the actual controlled object;

[0021] 2) Configure the test environment: select the simulation environment model of the whole vehicle, which is the simulation environment model except for the VCU control model, including the controlled object model, the sensor model and t...

Abstract

The invention relates to a testing method in a circuit of a battery electric vehicle (BEV) vehicle-control unit (VCU) model. The testing method in the circuit of a BEV VCU model comprises steps of configuration of a tested model, allocation of a testing environment, selection of a testing case, beginning of a test, reading of a test report and a regression test. The testing method in the circuit of a BEV VCU model has the advantages that a simulation environment model needed by a VCU control algorithm model is established under a Matlab / Simulink environment, then a VCU model is formed and a Simulink model is tested in the circuit, testers carry out the simulation of the BEV VCU model in the circuit through the vehicle operation conditions and failure conditions defined in the circuit testing configuration interface of the model, therefore purpose of testing the VCU control model is achieved.

Description

technical field [0001] The invention belongs to the field of new energy vehicles, and in particular relates to an in-loop testing method for a pure electric vehicle vehicle controller model. Background technique [0002] Electric vehicles are widely considered to be one of the main ways to solve problems such as vehicle exhaust pollution and oil energy shortages. With the rapid development of electric vehicles, the performance and reliability requirements of their core components are becoming more and more important. [0003] The power system of an electric vehicle is mainly composed of a power battery, a power battery manager (BMS: Battery Management System for short), a drive motor, a starter motor controller (MCU: Motor Control Unit for short), and a vehicle controller (VCU: Vehicle for short). Control Unit) composition. Among them, the VCU is responsible for the monitoring of the vehicle state, the control of the driving torque, the energy management of the vehicle, the...
