Semi-physical real-time hybrid simulation platform and simulation method for single-PC wet-type dual-clutch transmission

Abstract

The invention provides a single PC wet-type dual-clutch transmission semi-physical real-time hybrid simulation platform. The simulation platform comprises a virtual controller part and a field system part which transfer and exchange information by a data information exchange interface board card and an electronic control unit of the dual-clutch transmission, the electronic control unit of the dual-clutch transmission obtains a vehicle running signal by the data information exchange interface board card, performs comprehensive treatment and judgment according to the obtained signal so as to make a gear shifting decision for controlling actions of various solenoid valve; meanwhile, the virtual controller part obtains gear information from the data information exchange interface board card to simulate the actual vertical running state and display data processing results in real time. The simulation platform has the advantages that only one PC or industrial PC is required and a field actual physical signal is introduced in the simulation platform, which helps improve data accuracy of a simulation system and credibility of experimental results. And the simulation platform also has the advantages of low cost and strong practicability.

Description

technical field [0001] The invention relates to a simulation platform of a dual-clutch transmission, in particular to a half-physical real-time hybrid simulation platform and a simulation method of a single-PC wet-type dual-clutch transmission different from xPC or other hardware-in-the-loop methods. Background technique [0002] The perfect software program of the automatic transmission electronic control system, the reliability and stability of the hardware system directly affect the performance of the entire transmission system, so how to find a fast, reliable, practical and low-cost automatic transmission controller development approach It is very necessary. In fact, such embarrassing situations are often encountered in the actual engineering research and development process. For example, satisfactory software programs and control strategies can be obtained on the computer, but the effect is very poor once it reaches the actual application, making people feel at a loss. ...

[0002] The perfect software program of the automatic transmission electronic control system, the reliability and stability of the hardware system directly affect the performance of the entire transmission system, so how to find a fast, reliable, practical and low-cost automatic transmission controller development approach It is very necessary. In fact, such embarrassing situations are often encountered in the actual engineering research and development process. For example, satisfactory software programs and control strategies can be obtained on the computer, but the effect is very poor once it reaches the actual application, making people feel at a loss. , this is because pure digital simulation does not take into account the on-site signal characteristics of the actual physical system, which will inevitably lead to a large difference between the digital simulation results and the actual application results. This situation will inevitably delay the product development cycle and reduce the development success rate. At present, there is no semi-physical real-time hybrid simulation platform and simulation method developed by adopting the technical scheme of the present invention.
