Abstract

The invention relates to an automobile double-clutch automatic speed changer hardware-in-the-loop simulation test bed; a host machine establishes a digital simulation mathematical model of multiple working conditions of the automobile and converts the digital simulation mathematical model into a C code format, the C code format is received and downloaded to a CPU by a target machine through an Ethernet, an electric control unit controls an executive motor of the two clutches and the executive motor of a synchronizer, and the displacement of the clutch is received through a PCL board card in order to control the operation of the digital simulation model of various working conditions of the automobile stored in the target machine and the information fed back by the target machine. The invention has the advantages of realizing the hardware-in-the-loop of a TCU and an actuator, the more accurate prediction results of various control parameters, optimizing the control parameters of extremely dangerous situations in the prophase of research and development of a DCT electronic control system, simplifying the test environment, and the tested various performances and gained optimization parameters closer to the real vehicle test.

Description

Hardware-in-the-loop simulation test bench for automotive dual-clutch automatic transmission technical field The invention relates to a simulation test bench, in particular to a hardware-in-the-loop simulation test bench for an automobile dual-clutch automatic transmission. Background technique The drive train of a vehicle equipped with a dual-clutch automatic transmission (Dual Clutch Transmission, referred to as DCT) is composed of the engine, DCT, DCT electronic control unit (Transmission control unit, referred to as TCU), synchronizer and dual-clutch executive motor. Each executive motor and TCU with accurate mathematical models are established to implement hardware-in-the-loop. Based on the xPC target working environment, the mathematical model of the executive motor and engine, the digital simulation model of various operating conditions of the DCT and the real-time communication of the TCU are realized. The engine, DCT and The running state of each executive motor i...
