Problems solved by technology

[0003] The existing plug-in hybrid electric vehicle energy management hardware-in-the-loop simulation platform mainly adopts the commercialized tool chain developed by the traditional vehicle control system, such as LabCar system, dSPACE system, ADRTS system, etc. The download of the model and the tool chain The configuration process is relatively cumbersome
At the same time, the vehicle control system of plug-in hybrid electric vehicles mostly uses CAN bus for coordinated control of various power components. The energy management of electric vehicles has high requirements on the performance of the CAN bus, and the existing hardware-in-the-loop simulation platform cannot monitor the signals on the CAN bus and the messages transmitted by the bus in real time, that is, it is impossible to analyze the topology of the CAN bus and its communication quality. Monitoring and evaluation, thereby reducing the efficiency of development of vehicle energy management strategies for plug-in hybrid electric vehicles

Description

technical field [0001] The invention relates to an energy management strategy hardware-in-the-loop simulation platform, in particular to a plug-in hybrid electric vehicle energy management strategy hardware-in-the-loop simulation platform. Background technique [0002] Plug-in hybrid electric vehicle is a special configuration that combines the characteristics of pure electric vehicles and conventional hybrid electric vehicles. It carries a large-capacity power battery pack that can be charged through the grid, and has a certain pure electric mileage. Due to its special energy distribution structure, the control of the power source of plug-in hybrid electric vehicles is more complicated than that of traditional hybrid systems. Therefore, efficient and energy-saving energy management strategies have become the key to the research of plug-in hybrid electric vehicles. Hardware-in-the-loop simulation is a key step in the "V" cycle development process of the vehicle control syste...
