Integrated thermal management method for fuel cell vehicle and implementation method of rapid control prototype thereof

Abstract

The invention provides an integrated thermal management method for a fuel cell vehicle and an implementation method of a rapid control prototype thereof. The integrated thermal management takes heat pumps as core, and is integrated by fuel cell thermal management, auxiliary energy thermal management, motor and power electronic thermal management, and passenger cabin thermal management. The coordination and the control are realized by an integrated control unit. The rapid control prototype system comprises an upper computer, a rapid control prototype, and a controlled object. The upper computermainly realizes the functions of system mathematical model construction, simulation verification, code automatic generation, hardware-in-loop simulation, parameter calibration, and real-time monitoring; the rapid control prototype comprises a software platform and a hardware platform, wherein the software platform comprises an underlying driver function and a task execution framework, and the hardware platform comprises a signal conditioner and a data acquisition card; and the controlled object is a target system in a whole vehicle or a test bench. According to the integrated thermal management method for the fuel cell vehicle and the implementation method of the rapid control prototype thereof, the development of the integrated thermal management and control for the fuel cell vehicle issimplified, and the development efficiency is improved.

Description

technical field [0001] The invention belongs to the field of electric vehicles, and in particular relates to a method for comprehensive thermal management of a fuel cell vehicle and a method for realizing a rapid control prototype thereof. Background technique [0002] Due to its high efficiency, zero emission, low magnetic and low noise signal characteristics, low operating temperature, and weak infrared radiation, fuel cell vehicles have become a research hotspot in new energy vehicles. However, the main parts of fuel cell vehicles, such as fuel cell systems, auxiliary energy systems, motors and power electronic systems, have a great relationship between their operating characteristics and temperature, especially the fuel cell system, which is extremely sensitive to temperature; at the same time, the passenger compartment The temperature of the car should also be kept within a certain temperature range to meet the comfort requirements of the people in the car. The heat pu...
