Method for estimation of temperature in intake manifold of internal combustion engine, involves determining estimated value for temperature in intake manifold of internal combustion engine by kalman filter

摘要

The method involves determining an estimated value for the temperature in the intake manifold of an internal combustion engine (2) by a kalman filter. A measured value is provided for the temperature in the intake manifold by a temperature sensor and during a stationary condition the estimated value for the temperature in the intake manifold is corrected on basis of this measured value. An independent claim is also included for a control device for a motor vehicle.
