Abstract

The invention discloses a hardware-in-the-loop simulation system of an automatic mechanical transmission (AMT) controller, which comprises a LABCAR system, wherein the LABCAR system comprises a gasoline engine vehicle model, the gasoline engine vehicle model comprises a vehicle submodel, the vehicle submodel comprises an automatic transmission case submodel, and the automatic transmission case submodel comprises a signal collection model, a transmission system model, an execution mechanism model and a shift-level processing model. The invention also discloses a method for the hardware-in-the-loop simulation system to automatically test the AMT controller. Due to the adoption of the hardware-in-the-loop simulation system and the method, the interaction between vehicles and the AMT controller can be actually simulated, so different tests can be performed on the AMT controller.

Description

technical field [0001] The present invention relates to a hardware in the loop simulation (hardware in the loop simulation) system for automobile development and testing, in particular to a hardware in the loop simulation system of an AMT (automated mechanical transmission, automatic mechanical transmission) controller. Background technique [0002] The automatic mechanical transmission (AMT) of automobiles involves multidisciplinary fields such as mechanics, hydraulics, electronics, and control. Its working conditions are very complicated and have extremely high safety requirements. Transmission Control Unit) design complexity. [0003] AMT controller needs a long-term process from system architecture design, single function development, testing, to software integration, system testing and calibration. In its software development process, it usually adopts the practice of conceptual design-modeling and simulation-code generation-software integration-testing. [0004] In t...
