Computing an Operating Strategy for an Active Body Control with Dynamic Programming in the Automotive Area

Customers expect a modern automobile to be comfortable and safe. The spring damper system in the wheel suspension is the most important component to ensure both. During the design process of the spring damping a physically based conflict between these two main functions arises. For passive systems improving the driving comfort will always worsen the driving safety and vice versa. We developed an active air spring damper system (AASD) which enables us to increase the driving comfort while keeping driving safety constant. Since auxiliary power is necessary for the adaptive control a new challenge is to handle the limited energy supply. In this paper we present a primal heuristic for the determination of an operating strategy for the AASD for a given route and a given limited energy supply. We appraise feasible solutions and present runtime benchmarks. Marlene Utz, Phillipp Hedrich, and Peter F. Pelz
