Existing diagnostic systems on internal combustion-engine (ICE) commercial vehicles are primarily designed for diagnosing faults on body, chassis, powertrain and network systems. Hybrid-electric vehicles (HEVs) and electric vehicles (EVs) will have some similar components for the ICE, plus many new components and diagnostic requirements for the electrical traction system. This paper derives diagnostic requirements for hybrid/EV commercial vehicles and illustrates these with the approaches used on a prototype through-the-road hybrid electric vehicle (HEV). The differences and potential conflicts with existing ICE-vehicle diagnostics are drawn and possible solutions derived.
