A method for predicting a future camshaft position includes approximating a regulating circuit or a part of a regulating circuit that includes at least an adjusting device by a transfer function, and ascertaining a future camshaft position on the basis of the transfer function. An engine control unit is also provided.

Method for predicting a phase position of a camshaft

A control unit for controlling a phase angle of a first camshaft of an internal combustion engine includes a first characteristic diagram signal generator for determining a dynamic setpoint phase angle of the first camshaft, a second characteristic diagram signal generator for determining a static setpoint phase angle of the first camshaft, and a first interpolator for determining a corrected setpoint phase angle of the first camshaft based on the dynamic setpoint phase angle of the first camshaft and on the static setpoint phase angle of the first camshaft. A motor vehicle including a control unit for controlling a phase angle of a first camshaft of an internal combustion engine and a method for controlling a phase angle of a first camshaft of an internal combustion engine are also provided.

Motor vehicle, control unit and method for controlling a phase angle of a camshaft

A motor vehicle electrical system having a starter and a first energy store, which are arranged in a first region of the motor vehicle electrical system, and a generator and a second energy store, which are arranged in a second region of the motor vehicle electrical system, wherein, a switching element is arranged between the first and the second region of the motor vehicle electrical system, wherein the switching element has at least two switching states, wherein, in a first switching state, a current can flow only from the first region toward the second region and, in a second switching state, the first and second region have a through-connection to one another, wherein the second energy store is connected to the generator via a DC/DC converter, wherein, via a second switching element, the starter is connected directly to the second energy store.
