Selective wake-up based partial networking for battery life extension in two-wheeler ECU architectures

Modern two-wheeled vehicles increasingly integrate multiple Electronic Control Units (ECUs) for both critical safety functions and non-critical comfort features. In traditional Controller Area Network (CAN) bus architectures, any message transmission wakes up all connected ECUs regardless of functional relevance, causing elevated standby power consumption critical for motorcycles with limited battery capacity. This paper presents a simulation-based proof-of-concept of partial network (PN) for two-wheelers based on Automotive Open System Architecture (AUTOSAR) architecture and ISO 11898-6 selective wake-up mechanisms. The proposed system classifies ECUs by criticality, keeping critical ECUs continuously active while enabling selective activation of non-critical ECUs only when functionally required. Simulation and real-time monitoring were conducted using Vector CANoe software with custom Communication Access Programming Language (CAPL) scripts. Additionally, selective diagnostics capability allows targeted ECU diagnosis without waking unnecessary nodes, improving diagnostic efficiency and reducing CAN bus traffic. The contribution of the work is in the area of energy-efficient vehicle electronics for two-wheeler systems and aligns with the sustainable development goals of clean energy and the use of resources in a responsible manner.
