Parts simulation design and simulation training system combined with hardware-in-the-loop

In order to improve the simulation effect of automobile parts, this paper analyzes the simulation design of automobile parts with hardware-in-the-loop, and verifies the system through setting up a simulation system to improve the design effect and practical effect of automobile parts. Moreover, this paper proposes a dual-core HILoC architecture suitable for small-scale dynamic system simulation, and a dual-core data exchange architecture based on IPC mechanism communication, which solves the problem of dual-core shared memory utilization and improves the communication efficiency between dual-cores. In addition, this paper proposes a hardware-on-chip real-time simulation (HILoC) system based on dual-core technology. There are two ways to realize data exchange between two cores, and one is to store data in shared memory, which can be operated by both cores. After that, this paper takes the pure electric vehicle with direct drive structure equipped with reducer as the target to carry out experimental research. Based on the comprehensive analysis of the powertrain structure and forward simulation characteristics of pure electric vehicle, the longitudinal dynamic model of the whole vehicle is established by using modular modeling idea. Finally, this paper verifies that the method model proposed in this paper has good effect through experimental research. © Z. Ge et al., Published by EDP Sciences, 2024.
