Abstract
The invention is a method and an apparatus for determining travel data of a travel device when wheels or rollers of the travel device intermittently have ground contact. The apparatus has an odometer on at least one measuring roller. For the correct determination of the travel data, there is a correcting device for correcting the path length measured by the odometer in the case of interruptions of the ground contact of the measuring roller. In the case of established, sporadic interruptions of ground contact, the measured path length is corrected for obtaining the actually covered path length.
Claims46
An apparatus for determining travel data of a travel device, that includes rollers which have intermittent ground contact, at least one of the rollers being a measuring roller, said apparatus comprising:
- an odometer adapted to be coupled to the at least one measuring roller to register an initial measured path length;
- and
- a correcting device for correcting the initial measured path length for an effect of the intermittent ground contact with the at least one measuring roller, to cause the odometer to register a corrected measured path length which is travelled by the travel device.
A method of determining travel data of a travel device that includes rollers which have intermittent ground contact, at least one of the rollers being a measuring roller associated with an odometer, the method comprising:
- during movement of the travel device, correcting an initial measured path length for an effect of the intermittent ground contact by the at least one measuring roller to provide a corrected measured path length traveled by the travel device during movement which includes the intermittent ground contact.
