Process and system for determining fuel consumption of a motor vehicle
First Claim
1. 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.

Abstract
A process and system are provided for determining fuel consumption of a motor vehicle. A first mean fuel consumption, which cannot be reset under a user'"'"'s influence, is determined. A second mean fuel consumption, which can be reset under a user'"'"'s influence, is determined as a function of several measured values. A third mean fuel consumption is determined as follows: (a) at the beginning of a predefined time period, which starts with a resetting of the second mean fuel consumption, 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. A signal indicative of the third mean fuel consumption is provided.

10. A device for determining fuel consumption of a motor vehicle, comprising:
-
a first mean fuel consumption determining unit, which cannot be reset under a user'"'"'s influence; a second mean fuel consumption determining unit, which is resettable under a user'"'"'s influence, as a function of several measured values; a third mean fuel consumption determining unit, said third unit being operatively configured to; (a) at a beginning of a predefined time period, which starts with a resetting of the second mean fuel consumption, set the third mean fuel consumption to be equal to the first mean fuel consumption; (b) between the beginning and the end of the predefined time period, which starts with a resetting of the second of the second mean fuel consumption influenced by the user, set the third mean fuel consumption 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, set the third mean fuel consumption to be equal to the second mean fuel consumption; and a signal indicative of the third mean fuel consumption.

11. A system for a motor vehicle, comprising:
a device for determining fuel consumption of the motor vehicle, the device comprising; a first mean fuel consumption determining unit, which cannot be reset under a user'"'"'s influence; a second mean fuel consumption determining unit, which is resettable under a user'"'"'s influence, as a function of several measured values; a third mean fuel consumption determining unit, said third unit being operatively configured to; (a) at a beginning of a predefined time period, which starts with a resetting of the second mean fuel consumption, set the third mean fuel consumption to be equal to the first mean fuel consumption; (b) between the beginning and the end of the predefined time period, which starts with a resetting of the second of the second mean fuel consumption influenced by the user, set the third mean fuel consumption 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, set the third mean fuel consumption to be equal to the second mean fuel consumption; and a signaling unit operatively coupled with the device for determining fuel consumption, the signaling unit receiving a signal indicative of the third mean fuel consumption from the device for determining fuel consumption and outputting a signal for a user of the motor vehicle.
