Micro-Hybrid vehicles, making use of belt-driven Integrated Starter Generators (Belt-ISGs), are systems providing both engine stop/start functionality and regenerative braking. As there is currently a gap in the knowledge available about new requirements based on customer usage for affected subsystems of a micro-hybrid vehicle, the need arises to understand customer requirements/usage well in order to avoid both system over- and undersizing. We present a new statistical approach to identify both passenger car requirements for the ISG-system (number of restarts required in vehicle life) and the impact of micro-hybrid functionality on battery wear (due to required load support during stop phases and due to engine restarts) based on real-world customer usage profiles. Real-world fuel consumption benefit can be estimated as well. The durability requirements for Micro-Hybrid vehicles depend on system calibration. The results of our analysis therefore allow a trade-off between fuel consumption benefit due to avoided idle time and reliability-target based system cost estimations and thus enable a clear understanding of this 'magic triangle'.
