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 means of 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.
Combining MicroAutoBox III and RapidPro ensures convenient advanced engine control development on the test bench and in the vehicle. The MicroAutoBox III prototyping system can execute computation-intensive embedded software algorithms, directly generated from Simulink models. It provides the necessary automotive bus interfaces to connect to other electronic control units and engine-specific I/O interfaces, such as crank, cam, lambda, and knock sensors and signal generation for injection and ignition signals. MicroAutoBox III also supports cylinder-pressure-based control development with its fast, analog input channels. By using the FPGA resource in MicroAutoBox III, you can even implement extremely fast control loops with an in-cycle response to allow for a control design for CAI or HCCI strategies. RapidPro is a scalable and modular system that adds off-the-shelf signal conditioning and power stage capabilities to the prototyping system.
