WAVE - real-time analysis

WAVE applications

Real-time analysis

WAVE-RT provides real-time, crank-angle resolved engine models for testing new engine management systems for both SiL and HiL analysis and rapid prototype control units (http://www.ricardo.com/rCube2) and mini computers equipped with ARM processor e.g. Raspberry PI (www.raspberrypi.org). It allows the design of advanced performance and emission control, emission and CO2 reduction, virtual sensors and OBD improvements.
