To capitalize on a market opportunity in Latin America for a range of medium- to heavy-duty vehicles, Iveco had to design, implement, test, and deliver a shift range inhibitor system for vehicles with 9- and 16-speed transmissions in about six weeks. The aggressive deadline required a compressed software development schedule that left no room for specification or implementation errors. Model-Based Design with Simulink and Simulink PLC Coder™ enabled Iveco engineers to complete the transmission management system on schedule using existing programmable logic controller (PLC) hardware.
