Abstract

An electrical connection arrangement on a vehicle comprising vehicle contact means connectable to an implement contact means associated with an implement. The vehicle and/or implement contact means is connectable to a control unit which determines wear or damage of the vehicle and/or implement contact means and the wear or damage is communicated to the vehicle operator.

Claims

1. An electrical connection arrangement on a vehicle comprising vehicle contact means connectable to an implement contact means associated with an implement, wherein said vehicle and/or implement contact means is connectable to a control unit which determines wear or damage of the vehicle and/or implement contact means and the wear or damage is communicated to the vehicle operator, characterised in that the control unit counts and displays the number of times the vehicle and/or implement contact means is re-connected.

2. An electrical connection arrangement as claimed in claim 1 wherein the control unit is installed on the vehicle.

3. An electrical connection arrangement as claimed in claim 1 wherein the control unit is installed on the implement.

5. An electrical connection arrangement as claimed in claim 1 wherein the control unit notifies the operator of wear or damage when a pre-determined number of re-connections is reached.

6. An electrical connection arrangement as claimed in claim 1 wherein control unit indicates whether the vehicle and/or implement contact means is connected or not.

7. An electrical connection arrangement as claimed in claim 2 wherein the vehicle contact means is connectable to an electronic Bus system of an implement and the control unit is sent a signal if the implement is connected.

8. An electrical connection arrangement as claimed in claim 1 wherein the vehicle or implement contact means and the control unit form an open circuit when an implement contact means is disconnected and a closed circuit with the implement contact means is connected.

9. An electrical connection arrangement as claimed in claim 8 wherein the control unit measures the resistance of the circuits and determines whether the vehicle contact means is connected or not.

10. An electrical connection arrangement as claimed in claim 1 wherein the control unit is connected to a temperature sensor which senses the temperature of the vehicle and/or implement contact means allowing the control unit to determine the resistance across the corresponding contact means and therefore whether that contact means is connected or not.

11. An electrical connection arrangement as claimed in claim 1 wherein the control unit is connected to an insulation monitor which compares a current applied to the vehicle contact means to the actual current flowing across the contact means and therefore determines whether an implement is attached to the vehicle contact means or not.

12. An electrical connection arrangement as claimed in claim 1 wherein wear or damage of the vehicle and/or implement means is determined by measuring the temperature or resistance of the vehicle and/or implement contact means.

13. An electrical connection arrangement according to claim 12 wherein the temperature or resistance of the implement contact means is measured and sent to an implement control unit and the implement control unit is connected to the vehicle control unit which notifies the operator of wear/and or damage of the implement contact means.
