Hybrid power control system hardware-in-loop experimental platform

Abstract

The invention relates to a hybrid power control system hardware-in-loop experimental platform. The hybrid power control system hardware-in-loop experimental platform is characterized by comprising an engine driving system, a motor driving and braking system, a hydraulic pressure control system, a power coupled system, a rode analog system, a flywheel, a signal detecting system, a power transmission system and a control and monitoring system. Controller sending signals respectively control a dynamometer controller, an engine controller, a motor controller and a hydraulic pressure braking system through a driving circuit and a filter circuit, and received feedback signals are sent to a computer to conduct monitoring. Coupling of engine output power and motor output power in different positions such as the front end of a speed changing box, the back end of the speed changing box and wheel surroundings of a driving wheel trough the power coupling systems of different positions is achieved. The hybrid power control system hardware-in-loop experimental platform can not only be used for detecting a hybrid power system of the coupling of the engine output power and the motor output power at the front end of the speed changing box, but also be used for detecting the coupling of the hybrid power system of the engine output power and the motor output power at the back end of the speed changing box or the wheel surroundings of the driving wheel.

Description

technical field [0001] The invention relates to a hardware-in-the-loop experiment platform, in particular to a hardware-in-the-loop experiment platform for a hybrid power control system that is applicable to testing various types of hybrid power control systems. Background technique [0002] During the research and development of the hybrid control system, after completing the simulation verification, in order to further test the control effect of the control system on the actual execution components, hardware-in-the-loop experiment verification and real vehicle verification are required. The real vehicle experiment cycle is long, the cost is high, and the risk It is also relatively large, so in the initial stage of hybrid vehicle control system development, hardware-in-the-loop test benches are usually used to test and verify its performance. [0003] However, there are various types of hybrid power control systems, such as transmission front coupling type, transmission rea...

Problems solved by technology

The existing hybrid control system hardware-in-the-loop test platform is often only designed for a certain type of hybrid control system structure, which has poor versatility and cannot be widely used in other types of hybrid control systems. Therefore, it is urgent to develop a hardware-in-the-loop test platform that can be applied to multiple hybrid control systems at the same time.
