Abstract
A method and a control system for positioning a mine vehicle. Measurement of a distance travelled by the mine vehicle (1) is based on monitoring rotation of a wheel (3). In the invention, an error caused in the distance measurement by wear of the wheel (3) is compensated for automatically when the distance value obtained from monitoring is corrected by a correction factor. The value of the correction factor is updated at predetermined intervals during use.
Claims10
A method of determining a distance travelled by a mine vehicle provided with positioning,
- the mine vehicle comprising:
- a chassis;
- several wheels;
- an engine;
- power transmission for transmitting a torque from the engine to at least one wheel;
- and a control system including at least a first control unit arranged in the vehicle;
- and means for determining the distance travelled;
- and the method comprising:
- monitoring rotation of at least one wheel and calculating the length of the distance travelled in the control system on the basis of the monitoring result and the diameter of the wheel monitored,
- determining a correction factor, which changes in relation to a change in the wheel diameter;
- correcting the value of the distance travelled obtained by calculating by means of the correction factor,
- and updating the value of the correction factor at predetermined intervals.

A control system for a mine vehicle comprising at least:
- a first control unit,
- means for monitoring rotation of at least one wheel of the mine vehicle,
- and wherein
- the control system being arranged to determine a distance travelled by the vehicle on the basis of the wheel diameter,
- the control system is arranged to automatically correct the result from the distance measurement by a correction factor,
- and the value of the correction factor is arranged to be updated at predetermined intervals, and thus the trend in the change of the wheel diameter is taken into account.
