This paper describes the development of hybrid control software for a parallel hybrid vehicle with compressed-natural-gas engine. The underlying project is shortly introduced. Then the software development process is presented with emphasis on different stages of testing and the requirements for the test environment software. Hereafter the tasks of the hybrid control software are explained. Finally a short description of the control strategy is given. A development process for hybrid-specific control software was presented in this paper. Emphasis was put on the multi-stage testing reaching from PC-based non-real-time simulation to real-time HiL (Hardware-in-the Loop) simulation, and tests including several real aggregates on a test bench. Important prerequisites were described, especially the exact definition of different interfaces. Afterwards the tasks of the hybrid control software were explained, especially the extended gateway function. Finally the hybrid control strategy was shortly presented.
