Simulation investigation of individual bumps recognition posibilities for damping control and possible suspension performance improvements

Abstract

The paper presents the methodology and the results of simulation investigation of a possibility to recognize individual bumps on an A and B class roads of ISO 8608 standard on the base of suspension forces power. The algorithm for adjusting damping level for a short time after encountering such obstacles in order to achieve quicker dissipation of energy in a suspension system was presented as well as a potential way of improving comfort due to this control. Analysis of suspension forces power showed that there is a possibility to recognize individual bumps for certain cases, which will be discussed further. Analysis of the results of use of a specifically designed damping control shows that a small comfort improvement due to the change in control strategy is possible.
