Use of torque model at virtual engine conditions

The invention relates to a use of torque model at virtual engine conditions, more particular to a torque estimation system for a vehicle comprising an operating parameter module, a torque estimation module, and an estimation control module. The operating parameter module determines an estimated engine operating parameter based on engine speed. The torque estimation module estimates engine torque based on the engine speed and the estimated engine operating parameter. The estimation control module provides a plurality of engine speeds to the operating parameter module and the torque estimation module to determine estimated engine torque as a function of engine speed.
