Alma Automotive developed and put in production the first wideband oxygen sensor simulator. It allows for a complete ECU testing solution, enabling closed loop control on the air flow ratio. The system is conceived to have an easily connection to any HIL system with a wide choice of controlling buses, without any additional HW. The system is developed for SLSC format or in a stand-alone version. There are two version with two or four independent channels. The model-based control allows to simulate a wide variety of wideband sensors. The SW enables the use of an independent setpoint of air flow ratio and temperature, via analog signals, ethernet bus (stand-alone version) or NI SLSC Bus (SLSC Version). The sensor simulation is complete, both the pumping cell and the reference cell electrical characteristics are integrated in a single simulation. The channel to channel isolation allows to connect multiple UEGO controllers to the single card without grounding and interference issues.
