Addressable LED/ Buzzer structures for signaling/ reflection for urban E-Bikes

This paper presents results from a study about an addressable LED wearable indicator system concept increasing visibility and safe interaction between E-bike users and other participants in urban traffic. To this end, we explore existing solutions for small and energy-efficient signaling devices. Exemplar we select one product as basic model, analyze its characteristics and in search of a more suitable functionality for the scientific project for autonomous cargo E-bikes “AuRa”, we offer new technical and design requirements. The conducted experimental part is based on investigating safety and ergonomics to QC-test some critical timings of selected LEDs. We want to integrate findings from this and upcoming studies to formulate construction indications for a future control hardware and software design as a proposal for the project “AuRa”.
