Abstract:
1. A method for reducing energy consumption of a motor vehicle having an internal-combustion engine and at least one electric onboard power supply to which at least a first electric consuming device is connected, the method comprising the acts of: detecting, by a driving situation detection device provided in the vehicle, a substantially imminent special driving situation based on at least one of a driver's previous behavior when steering the vehicle and a previous action of the vehicle, and upon detecting the substantially imminent special driving situation, causing the internal-combustion engine to change from a first operating condition into a second operating condition, wherein: in the first operating condition, the internal-combustion engine is operated with a first injection quantity and a first ignition point, in the second operating condition, the internal-combustion engine is operated with a second injection quantity higher than the first injection quantity and with a second ignition point, and the second ignition point is less favorable than the first ignition point with respect to a capacity of the internal-combustion engine in the case of the second injection quantity.
