Development of Road Friction Coefficient Estimation Logic

Article of Honda R&D Technical Review Vol.14 No.2

Summary

The further development of vehicle stability assist (VSA) and other such forms of vehicle dynamics control requires techniques for estimating the road friction coefficient more accurately and in real-time. The present research integrated non-linear tire characteristics data with vehicle side slip angle estimation logic to develop a new estimation logic that is more accurate and has greater response than the conventional logic. The estimation accuracy of this logic was further verified in tests with actual vehicles, thus demonstrating the validity of the developed logic.
