【摘  要】本文首先闡述基于dSPACE實(shí)時(shí)仿真系統(tǒng)構(gòu)建的傳統(tǒng)的AMT物理模型，主要包括發(fā)動(dòng)機(jī)模型、離合器模型、變速器模型、車(chē)輛動(dòng)力學(xué)模型等，然后基于此硬件在環(huán)系統(tǒng)驗(yàn)證TCU的主要控制功能能夠滿(mǎn)足軟件測(cè)試需求，通過(guò)該系統(tǒng)能提前發(fā)現(xiàn)潛在問(wèn)題，降低控制器開(kāi)發(fā)成本。

【Abstract】In this paper，a physical model of AMT was constructed based on dSPACE real-time simulation system，including engine model，clutch model，transmission model，vehicle dynamics model，etc. in order to obtain more close to the real vehicle vehicle dynamics simulation model. Based on this hardware in the loop system，the main control functions of TCU are verified，which can meet the needs of software testing. Through this system，problems are found in advance，and the cost of controller development is reduced.
