A method for operating a drive motor which is coupled to at least one wheel of a vehicle via a drive train. The drive motor is controlled using a dynamic model of the drive train. The model maps a relationship between a drive torque transmitted via the drive train and a deformation of the drive train.

A method for setting a working point of a slip controller for a wheel of a vehicle. Upon activating the slip controller, a torque at the wheel is controlled on the basis of the working point using a slip at the wheel, wherein the torque is monitored and a value of the working point is set to a previous value of the torque if the slip satisfies a condition.

A method for controlling slip of at least one wheel of a vehicle. In the method, at least one parameter of an action to be performed is read out from a matrix using a slip state of the wheel if the slip state is outside a target slip region of the matrix, wherein, for reading this out, a data field of the matrix associated with the slip state is determined and the at least one parameter is read out from the data field, wherein, for performing the action, at least one actuator of the vehicle is actuated using the parameter.

A method for controlling a temperature of a battery cell () in a battery module (), the method comprising the steps of: determining an initial temperature of the battery cell (); measuring a current (I) flowing into or out of the battery cell (); determining an actual temperature gradient of the battery cell () using a thermal battery cell model described by a differential equation, for which input values comprise at least the determined initial temperature and the measured current (I); comparing the determined actual temperature gradient of the battery cell () with a pre-defined desired temperature gradient; and automatically adjusting the current (I) flowing into or out of the battery cell () according to a result of the comparison.

A method for estimating a current open-circuit voltage characteristic of a battery, comprising acquiring a portion of an actual open-circuit voltage characteristic of the battery, detecting or defining a significant point in the acquired portion of the actual open-circuit voltage characteristic, identifying a point, in a characteristic curve of an anode potential of the battery and/or in a characteristic curve of a cathode potential of the battery, that is associated with the significant point, shifting and/or scaling the characteristic curve of the anode potential and the characteristic curve of the cathode potential on the basis of the position of the significant point with respect of the associated point, until the acquired portion is simulated by combination of the shifted and/or scaled characteristic curves, and calculating the current open-circuit voltage characteristic on the basis of the shifted and/or scaled characteristic curves.
