Hybrid electric vehicles (HEV) typically have complex interaction between different powertrain devices and incorporates complex electronic control unit (ECU) network. For the electrified vehicles of the future, comprehensive ECU tests are more necessary than ever before, as the complexity and amount of embedded software increases at a breathtaking speed. The V-cycle is a widely recognized approach in the development of ECUs spanning from offline controller development to the final implementation on production hardware. This paper describes a case study with a focus on electric drive components and electric drive controller development. The V-cycle for motor controller development involving phases control design, rapid control prototyping and target implementation is explained in detail. The model components needed for HEV simulation were selected from dSPACE Automotive Simulation Models (ASM).
