The automobile industries is forecasted to struggle for researching and developing green vehicles such as EV(Electric Vehicle),HEV(Hybrid Electric Vehicle), PHEV(Plug-in HEV) and FCEV(Fuel Cell Vehicle). One of advantages with ECOfriendly vehicles is able to use regenerative braking force. It means that it increases energy efficiency with cooperative controls of regenerative braking to reduce the heat loss due to the friction brake. Therefore, Fuel cell brake system needs basically not only conventional brake function but support function for regenerative braking. In addition to, the safety system like a brake system be required more accurate and complicated software for its stability. As a result, the software of ECO-friendly brake system gets heavy and complex. This paper proposed the optimized proto software(SW) for fuel cell brake system. The proto SW’s architecture and compensation designs are proposed to preempt verified application SW and to reduce development duration without AUTOSAR platform. The proposed proto SW based on firmware is verified enough on the rig. Before migration with AUTOSAR platform SW, Application SW is able to be verified and confirmed under the proto SW. As a result, it makes to reduce SW development period because Application SW can be developed in parallel with AUTOSAR platform.
