Device and method of simulation and testing of finished car controller of hybrid power car

Abstract

The invention discloses a device and a method of simulation and testing of a finished car controller of a hybrid power car. Due to the fact that a PCI interface and a micro processor are used for communication, the device of simulation and testing of the finished car controller of the hybrid power car has the advantages of being good in reliability, high in transmission rate of data, and good in extendibility. Due to the fact that a mathematical model of a power unit is used for simulating a working state of an actual power unit, cost of a system is greatly reduced. The device of simulation and testing of the finished car controller of the hybrid power car comprises a micro processor unit, a PCI bus processing unit, a display unit and an interface board card. The display unit and the PCI bus processing unit are respectively connected with the micro processor unit. The interface board card is connected with the PCI bus processing unit through a PCI bus. The interface board card is connected with the finished car controller to be detected. Therefore, configuration can be conveniently carried out on the structure of a finished car, relevant power unit parameters, an operation spectrum / a road spectrum, and port attributes of an interface board, and the system is good in generality. When the device and the method of simulation and testing of the finished car controller of the hybrid power car are used for testing a hybrid power finished car controller, a test period is shortened, test cost is reduced, and test results are good in stability and high in accuracy.

Description

technical field [0001] The invention relates to a simulation and test device and method for a vehicle controller of a hybrid electric vehicle. Background technique [0002] Environmental pollution, the increasing severity of the energy crisis, and the city's need to balance the load on the grid have prompted the vigorous development of hybrid vehicles. At present, major domestic automakers, parts companies, schools and scientific research institutions are actively conducting research on hybrid vehicles.
