Method for controlling and/or regulating a transmission system (1) for a motor vehicle is provided. The transmission system is provided with at least one pressure accumulator (27), and each pressure accumulator is provided with an air chamber (46) and a hydraulic fluid chamber (45). The method includes the steps of: guiding a hydraulic fluid into at least one pressure accumulator (27)to make a gas volume of the pressure accumulator reduced and the real temperature and pressure of the gas increased, and/or exporting the hydraulic fluid from the at least one pressure accumulator (27) to make the gas volume of the pressure accumulator (27) increased, and the real temperature and the pressure of the gas reduced, acquiring the measurement pressure of the gas in the at least one pressure accumulator (27) with at least one pressure sensor (47) corresponding to a first time delay of the real pressure of the gas according to a time variation, determining the initial temperature of the gas, determining the ambient temperature of the pressure accumulator (27), determining the temperature of the hydraulic fluid guided and/or exported the pressure accumulator (27), performing a model calculation by using the initial temperature of the gas, the ambient temperature of the pressure accumulator (27), the measurement pressure of the gas and the temperature of the hydraulic fluid guided and/or exported the pressure accumulator (27), calculating the model temperature of the gas by the model calculation, and calculating the gas volume by using the model temperature of the gas.
