First Claim
1. A monitoring apparatus for a vehicle including a plurality of sensors for detecting a plurality of vehicle functions and conditions and for producing corresponding sensor signals, said monitoring apparatus comprising:
- a console including operator actuatable control means, and control circuit means including means for calculating wheel slippage of at least one drive wheel of said vehicle, said calculating means including means responsive to sensor signals corresponding to the ground speed of said vehicle and to sensor signals corresponding in a predetermined fashion to the rotational speed of said at least one drive wheel for calculating a predetermined relationship therebetween; and
said control circuit means including recording means responsive to actuation of said operator actuatable control means for recording said calculated relationship as a reference value when said vehicle is being operated under conditions where there is substantially no slippage of said drive wheel, thereby calibrating said calculating means to calculate wheel slippage in response to said sensor signals corresponding to ground speed and to rotational speed and in accordance with said reference value.

Abstract
A monitoring apparatus for a vehicle such as a tractor comprises a console including controls and a control circuit for calculating wheel slippage of at least one drive wheel of the vehicle and responsive to engine RPM of the vehicle and to the rotational speed of the drive wheel for calculating a predetermined relationship therebetween. The control circuit is also responsive to actuation of the controls for setting the calculated relationship equal to a predetermined reference value when there is substantially no load on the vehicle, and hence minimum slippage of the drive wheel, in each of a plurality of ranges of gear ratios of the vehicle, thereby calibrating the control circuit to calculate wheel slippage for each of these ranges of gear ratios. The console also mounts an observable indicator and the control circuit also calculates other variables such as vehicle speed and engine RPM and actuates the observable indicator when the calculated values deviate from preselected values.
