In this article the influence of the oil temperature on damper behavior was analyzed. Furthermore, two different methods were shown to estimate the damper oil temperature. Two thermodynamic models were designed to estimate the operating oil temperature. Both models are different in their mathematical complexity, so they are recommended for different degrees of accuracy. The one-zone temperature model works along an accuracy of estimation of 10 K. The integration of this simplified model on an automotive control unit is easy, as well as its parameterization. The multi-zone model is more complex. This model is more suited for computerbased simulations and provides an operational accuracy of estimation of less than 5 K. Apart from the estimated oil temperature to be presented, this model determines the overall temperature distribution in the vibration damper.
