Abstract
Official abstract text for this publication.
A method is provided for reducing the energy consumption of a motor vehicle having at least one electric on-board power supply system to which at least one electric consuming device is connected. For implementing an efficient on-board power supply system which, in addition, contributes to the reduction of the energy consumption of a motor vehicle, the voltage level and/or power level of the electric on-board power supply system is kept at a first, low level during a first operating condition of the motor vehicle. The voltage level and/or power level of the electric on-board power supply system is temporarily raised to a second, higher level in a second operating condition of the motor vehicle. A driving situation detection device provided in the vehicle recognizes a largely directly imminent special driving situation as a result of the preceding behavior of the driver when controlling the vehicle and/or of the vehicle, in advance, and causes the voltage level and/or the power level of the electric power supply system to be temporarily raised to the second, higher level.
First claim
Opening claim text (preview).
What is claimed is: 1. A method of reducing energy consumption in a motor vehicle having at least one electric on-board power supply system to which at least one electric consuming device is operatively coupled, the method comprising the acts of: maintaining at least one of a voltage level and power level of the electric on-board power supply system at a first level during a first operating condition of the motor vehicle; temporarily raising the at least one of the voltage level…
