Abstract

A pedometer and a method for recording a distance covered. The pedometer includes an acceleration sensor by which the movement of the pedometer is recorded. In order to be able to ascertain the number of paces and the distance covered from the movement, an evaluation unit is provided which evaluates the signals of the acceleration sensor. If the carrier of such a pedometer is moving not only in one plane, but also uphill and downhill, inaccuracies occur in the ascertainment of the route which cannot be rectified only by an acceleration sensor. For this purpose, a pressure sensor is integrated into the pedometer, by which the evaluation unit is also able to take into account the influence of the change in altitude during the movement, whereby the route covered is able to be ascertained more accurately.

Claims

1. A pedometer for recording a route covered, comprising:

an acceleration sensor;

an evaluation unit adapted to generate a route signal for a route covered as a function of the acceleration signals generated by the acceleration sensor; and

a pressure sensor, the evaluation unit additionally taking into account a pressure signal generated by the pressure sensor during the generation of the route signal.

2. The pedometer as recited in claim 1, wherein the pressure sensor generates the pressure signal as a function of environmental pressure.

3. The pedometer as recited in claim 1, wherein the evaluation unit generates an altitude signal as a function of the pressure signal.

4. The pedometer as recited in claim 1, wherein the evaluation unit generates an altitude signal as a function of the acceleration signal and the pressure signal.

5. The pedometer as recited in claim 3, wherein the evaluation unit stores an altitude profile of the route covered.

6. The pedometer as recited in claim 1, wherein the pedometer has a display which displays at least one of:

a number of paces, the route covered, a calorie usage on the route covered, and an altitude profile of the route covered.

7. A method for recording a route covered, comprising:

generating a route signal representing the distance covered as a function of an acceleration signal of an acceleration sensor; and

generating a pressure signal by a pressure sensor, the pressure signal being taken into account for the generation of the route signal.

8. The method as recited in claim 7, wherein the pressure signal represents an environmental pressure.

9. The method as recited in claim 7, wherein an altitude profile of the route covered at least one of generated and stored from the pressure signal, in conjunction with the acceleration signal.

10. The method as recited in claim 7, further comprising:

displaying on a display at least one of;

a number of paces, a route covered, a calorie usage on the route covered, and an altitude profile of the route covered
