Abstract:
1. A method for stabilizing an on-board electrical system of a vehicle electrical system, including at least one battery, at least one rotational inertial load driven by an electric motor and a device configured to detect a state that is critical to the on-board electrical system, comprising: detecting a critical voltage state of the on-board electrical system by the device; in response to the detection of the critical voltage state and during the critical voltage state, driving the rotational inertial load by the electric motor such that the rotational inertial load stores rotational kinetic energy; and during the critical voltage state of the on-board electrical system and during a subsequent voltage drop of the on-board electrical system, driving the electric motor by the stored rotational kinetic energy of the rotational inertial load to generate electrical energy and supply the electrical energy to the on-board electrical system.
