The invention discloses a simulation platform for a vehicle control unit of a plug-in hybrid electric vehicle. The simulation platform comprises a dynamometer system, a data processing module, a vehicle simulation system and an environment simulation system, and is characterized in that the data processing module is connected with the dynamometer system and the vehicle simulation system and used for providing real-time data exchange for the dynamometer system and the vehicle simulation system; the environment simulation system is connected with the vehicle simulation system; the dynamometer system is used for acquiring characteristic parameters of a real motor and a real engine; and the environment simulation system is used for providing external environment information and road condition information for the vehicle simulation system. The simulation platform can a simulation test, which is completely consistent with the real environment, on the vehicle control unit, existing hardware design and control algorithm problems are discovered through testing, problems encountered by the vehicle control unit in practical debugging are reduced, the development efficiency of the vehicle control unit is improved, the aboard error rate is reduced, the test cost is lowered, the product quality is improved, and the development period of the HCU is shortened.

Description

technical field [0001] The invention relates to the field of hybrid electric vehicles, in particular to a simulation platform for a vehicle controller of a plug-in hybrid electric vehicle. Background technique [0002] In recent years, with the aggravation of environmental pollution and energy shortage, the problem of motor vehicle exhaust emissions has attracted more and more attention. At the same time, petroleum is a non-renewable resource. How to reduce the dependence of automobiles on traditional petroleum fuels is crucial to building a resource-saving society. Therefore, facing the dual pressure of environmental pollution and resource shortage, new energy vehicles have become the focus of research at home and abroad. New energy vehicles include pure electric vehicles, extended-range electric vehicles, hybrid vehicles, fuel cell electric vehicles, hydrogen engine vehicles and other new energy vehicles. At present, the main directions of research in our country are hyb...

Problems solved by technology

Most of the current simulation platforms can only be used for HIL testing, and the structure of the engine and electric motor models is complex, and the testing efficiency is low

The environment is not built well enough to cover all test points. For example, application number 201511009983.6 discloses a hardware-in-the-loop simulation platform for plug-in hybrid electric vehicle energy management strategy. The environmental model of electric hybrid electric vehicles, especially the charging pile environmental model unique to plug-in hybrid electric vehicles, has the problem of not being able to fully realize the simulation environment of the vehicle controller
