Patent ID: 8560215

Claim:
A process for determining fuel consumption of a motor vehicle, the process comprising the acts of: determining a first mean fuel consumption, which cannot be reset under a user's influence; determining a second mean fuel consumption, which is resettable under a user's influence, as a function of several measured values; and determining a third mean fuel consumption; wherein: (a) at a beginning of a predefined time period, which starts with a resetting of the second mean fuel consumption influenced by a user, the third mean fuel consumption is set to be equal to the first mean fuel consumption; (b) between the beginning and the end of the predefined time period, the third mean fuel consumption is set to be a weighted mean of the first mean fuel consumption and the second mean fuel consumption; and (c) starting at an end of the predefined time period, the third mean fuel consumption is set to be equal to the second mean fuel consumption; and providing a signal indicative of the third mean fuel consumption.
