Abstract

Embodiments of the present invention provide apparatus comprising: at least one motor vehicle switchpack (121-135), the switchpack comprising input means operable to control the switchpack to provide a switchpack control output to a motor vehicle control system; and motor vehicle test apparatus (100T), the test apparatus comprising: a test apparatus control system comprising computing means (115); test apparatus switching means operable under the control of the test apparatus control system to control the at least one switchpack to provide the switchpack control output to the vehicle control system, the test apparatus control system being operable to monitor a response by the vehicle control system to the switchpack control output.

Claims

1. An apparatus comprising:

at least one motor vehicle switchpack, the switchpack comprising an input means operable to control the switchpack to provide a switchpack control output to a motor vehicle control system; and

a motor vehicle test apparatus, the test apparatus comprising;

a test apparatus control system comprising a computing device;

a test apparatus switch operable under the control of the test apparatus control system to actuate to control the at least one switchpack to provide the switchpack control output to the vehicle control system, the test apparatus control system being operable to monitor a response by the vehicle control system to the switchpack control output.

2. The apparatus of claim 1, wherein the test apparatus control system is operable to perform at least one action in dependence on the response of the vehicle control system to the switchpack control output.

3. The apparatus of claim 1, wherein the test apparatus control system computing device is operable to run computer program code, the test apparatus control system being operable to control the test apparatus switch to control the at least one switchpack to provide the control output under the control of the computer program code.

4. The apparatus of claim 1, wherein the test apparatus switch comprises a test apparatus switch device and the switchpack comprises a switch device, the switchpack input being operable to operate the switch device of the switchpack, the test apparatus switch device being operable by the test apparatus control system to control the switchpack to provide substantially the same output as the switch pack provides when the switchpack input is operated.

5. The apparatus of claim 4, wherein the test apparatus switch device is connected electrically in parallel with the switchpack switch device.

6. The apparatus of claim 5, wherein the switchpack switch device is operable to make or break an electrical connection between a first set of terminals of the switchpack, the test apparatus switch device also being operable by the test apparatus control system to make or break the electrical connection between the first set of terminals of the switchpack in a corresponding manner.

7. The apparatus of claim 4, wherein the switchpack switch device comprises a mechanically actuable switch.

8. The apparatus of claim 1, wherein the test apparatus switch comprises one selected from amongst mechanical switches and electronic switches.

9. The apparatus of claim 1, wherein the test apparatus switch comprises a mechanical actuator for actuating the switchpack input element under the control of the test apparatus control system.

10. The apparatus of claim 1, wherein the switchpack comprises a touch-sensitive display.

11. The apparatus of claim 1, wherein the switchpack comprises a remote control device such as a keyfob device.

12. The apparatus of claim 1, wherein the test apparatus control system is operable to read signals transmitted on a motor vehicle controller area network.

13. The apparatus of claim 1, wherein the test apparatus control system is operable to transmit signals on a motor vehicle controller area network.

14. The apparatus of claim 1 comprising a test apparatus removable overload protection element connectable to an electrical connector means of a vehicle electrical circuit overload protection apparatus, the test apparatus removable overload protection element configured to detect a flow of electrical current therethrough and configured to output outputting a signal to the test apparatus control system corresponding to an amount of electrical current flow therethrough.

15. The apparatus of claim 14, wherein the test apparatus removable overload protection element is operable to limit an amount of electrical current flowing through an electrical circuit of the motor vehicle.

16. A motor vehicle comprising the apparatus of claim 1.

17. A kit of parts comprising:

a motor vehicle test apparatus, the test apparatus comprising;

a test apparatus control system comprising a computing device;

a test apparatus switch operable under the control of the test apparatus control system to control at least one motor vehicle switchpack to provide a control output to the vehicle control system, the control output being substantially the same output provided by the switchpack when an input of the switchpack is operated, the test apparatus control system being operable to monitor a response by the vehicle control system to the switchpack control output.

18. The kit of parts of claim 17, further comprising at least one motor vehicle switchpack, the switchpack comprising an input operable by a user to control the switchpack to provide the control output to a motor vehicle control system.

19. The kit of parts of claim 17, comprising a current measurement element, the current measurement element being adapted to replace a removable overload protection element of a vehicle electrical circuit overload protection apparatus.

20. A method of monitoring operation of a motor vehicle comprising at least one switchpack, the switchpack comprising an input operable to control the switchpack to provide a switchpack control output to a motor vehicle control system, the method comprising:

providing a test apparatus control system having a computing device, and controlling a test apparatus switch via the test apparatus control system to control the at least one switchpack to provide the switchpack control output to the vehicle control system; and

monitoring, via the test apparatus a response by the vehicle control system to the switchpack control output.
