Method for avoiding overheating of a vehicle subsystem, the vehicle subsystem comprising a compressor with a pressure chamber, wherein the vehicle subsystem is switchable between an open state in which the subsystem is open towards a connected further subsystem and a closed state in which the subsystem is closed towards the connected further subsystem and wherein the further subsystem is an air suspension system which is connected to the vehicle subsystem by a controllable valve, characterised in that, the method comprises the steps of executing an Extended Kalman Filter on a control module that calculates an error between a predicted state model of the vehicle subsystem and a corresponding measured state model of the vehicle subsystem, the predicted state model comprising as parameters an estimated pressure inside the pressure chamber, an estimated ambient pressure, an estimated rotational speed of the compressor and an estimated fluid volume stream of the compressor, and the measured state model comprising as parameters a measured pressure inside the pressure chamber, a measured rotational speed of the compressor and a measured fluid volume stream of the compressor, and processes the calculated error to adjust the predicted state model, including adjusting the estimated ambient pressure, based on weighted uncertainties of the measured and estimated parameters; comparing the estimated ambient pressure to a predetermined ambient pressure default value; reducing a cut-off pressure target value of the vehicle subsystem by a reduction amount for a period of time, when the estimated ambient pressure is less than or equal to the predetermined ambient pressure default value. characterised in that, the method comprises the steps of executing an Extended Kalman Filter on a control module that calculates an error between a predicted state model of the vehicle subsystem and a corresponding measured state model of the vehicle subsystem, the predicted state model comprising as parameters an estimated pressure inside the pressure chamber, an estimated ambient pressure, an estimated rotational speed of the compressor and an estimated fluid volume stream of the compressor, and the measured state model comprising as parameters a measured pressure inside the pressure chamber, a measured rotational speed of the compressor and a measured fluid volume stream of the compressor, and processes the calculated error to adjust the predicted state model, including adjusting the estimated ambient pressure, based on weighted uncertainties of the measured and estimated parameters; calculates an error between a predicted state model of the vehicle subsystem and a corresponding measured state model of the vehicle subsystem, the predicted state model comprising as parameters an estimated pressure inside the pressure chamber, an estimated ambient pressure, an estimated rotational speed of the compressor and an estimated fluid volume stream of the compressor, and the measured state model comprising as parameters a measured pressure inside the pressure chamber, a measured rotational speed of the compressor and a measured fluid volume stream of the compressor, and processes the calculated error to adjust the predicted state model, including adjusting the estimated ambient pressure, based on weighted uncertainties of the measured and estimated parameters; comparing the estimated ambient pressure to a predetermined ambient pressure default value; reducing a cut-off pressure target value of the vehicle subsystem by a reduction amount for a period of time, when the estimated ambient pressure is less than or equal to the predetermined ambient pressure default value.
