Abstract
A virtual cylinder pressure sensor for use with an internal combustion engine. The sensor has one or more independent modules, each used to estimate a different cylinder pressure variable. Each module is trained using measurement data from a physical cylinder pressure sensor and a real engine. After the modules are trained, they can be embedded into the engine control unit of the same engine type, and used to estimate and predict the values for which they were trained.
