In the course of constantly rising energy costs and strict legal requirements, the realisation of individual mobility in the form of automobiles is facing great challenges. New drive concepts, such as electric mobility, are creating approaches that will make the use of cars financially feasible in the future. In order to increase range or reduce energy costs, all vehicle components, including the chassis, must be optimised for minimum energy loss.
The aim of energy-efficient chassis in the active area is the optimisation and new design of active systems in order to reduce the energy losses to a minimum. At the same time, the recuperation rate during braking can be significantly increased by an integrated control of active systems. This may result in effects on the driving dynamics in yaw, pitch and roll movements which may be noticeable to the driver and which have to be compensated as well as possible.
Based on the known perception thresholds of humans, the effects of an increased recuperation are considered and a coherent target behaviour is defined. Subsequently, the potential of various active systems to achieve this target behaviour while simultaneously increasing energy efficiency in cooperation with recuperation is examined.
