摘要：

In this paper a simplified engine model is introduced in order to estimate the combustion torque from angular velocity measurement, using a Kalman filter approach. It can be implemented on-board the vehicle. The proposed discrete state-space model works with angular rather than time-equidistant sampling. Signals from conventional angular speed sensors of available engine management systems are used, without additional hardware components. Errors introduced by the digital computation of the angular speed. as well as the mechanical imperfections of the target wheel, are also modelled and taken into account.
