Vehicle Dynamics Simulation in Extreme Driving Conditions

Article of Honda R&D Technical Review Vol.21 No.2

Summary

The increased weight produced by measuring instruments and the limited space available for such instruments make it a challenge to measure vehicle characteristics in extreme driving conditions such as circuit driving that take the vehicle to its performance limits. The ability to conduct bench simulations of vehicle behavior, that consider a variety of factors such as changes in the form of the vehicle and the forces acting on it, across a wide range of driving conditions, from standstill to extreme driving, would enable the measurement of physical characteristics which has been unlikely to be measured to date. Additionally, this would contribute to more precise analysis of vehicle characteristics during driving. Honda’s Dynamic Vehicle Simulator (DVS) was developed as a multi-axis test system with the capacity to enable simulation of vehicle behavior from standstill to extreme driving on the bench. A method of efficiently reproducing this wide range of driving conditions on the bench using the DVS has been developed. This method has enabled vehicle characteristics in the extreme driving range, which has previously been challenging to study in vehicle tests, to be analyzed on the bench.
