Development of Vehicle Dynamics Simulation System under Running Mechanical Control Device

Article of Honda R&D Technical Review Vol.15 No.1

Summary

A coupled simulation using concurrent execution of mechanical and control simulations was developed and applied to prediction of vehicle behavior while under mechanical control. Also, a technique for automatic generation of real-time programs based on mechanical models applicable to HIL simulators, which require real-time executable calculations, was developed. This greatly eased accounting for the influence of vehicle body mechanisms in the behavior of suspensions and other systems. Thus, it is now possible to carry out ‘paper experimental tries’ and HIL simulator tries of simulations of full vehicle behavior under control by systems such as EPS or VSA. Formerly difficult predictions of vehicle behavior due to steering wheel torque or in non-linear regions have become possible.
