Embodiment Construction
[0038] Attached below Figure 1-4 The specific embodiments of the present invention are described in further detail.
[0039] Such as Figure 1-4 The implementation of the present invention needs to be established on the existing engine hardware-in-the-loop simulation platform, that is, the engine real-time simulation model has been constructed and can be run on the real-time simulation platform; the engine control ECU has basic control logic, and its hardware interface meets the actual engine Various types of sensors for object configuration. The engine simulation model of the hardware-in-the-loop simulation platform replaces the real engine operation and is used in the experimental steps in the development of the engine ECU controller. The signal with physical meaning output by the engine real-time simulation model can be converted into an analog electrical signal physical quantity conforming to the characteristics of the sensor through the sensor interface model, and output th...
