Saving fuel and reducing emissions (NOx, CO2) requires continuous research on new operating processes for internal combustion engines. New control strategies have to be developed on the test bench and verified by test drives. The efficient development of these strategies requires systems that can communicate with the vehicle´s bus systems and provide the flexibility to connect various sensors and actuators to control the combustion process. New control strategies like homogeneous charge compression ignition (HCCI) or controlled auto ignition (CAI) require a very precise and extremely fast closed-loop control.
A combination of MicroAutoBox II and RapidPro ensures convenient advanced engine control development on the test bench and in the vehicle. The MicroAutoBox II prototyping system can execute computation-intensive embedded software algorithms, directly generated from Simulink models, and provides the necessary automotive bus interfaces to connect to other electronic control units. MicroAutoBox II also supports cylinder-pressure-based control development with its fast analog input channels. By using the FPGA resource of MicroAutoBox II, you can even implement extremely fast control loops with an in-cycle response to enable control design for CAI or HCCI strategies. RapidPro is a scalable and modular system which adds off-the-shelf signal conditioning and power stage capabilities to the prototyping system. It also provides engine-specific I/O interfaces, such as modules for lambda and knock sensors, and power stage modules for valves, relays and electric motors used in auxiliary units.
