Abstract

A riding lawn mower is provided with an electrical system. The electrical system includes a control module, transceiver modules, and a wiring system. The control module allows for programmably controlling electrical operations of the riding lawn mower. The transceiver modules are operably connected with respective devices of the riding lawn mower so as to communicate data between the respective devices and the control module. The wiring system comprising wires that electrically connect the transceiver modules with the control module/The wiring system includes a power wire that provide electrical power to the transceiver modules from the battery; and a data bus comprising a data wire that transmits data between the control module and the transceiver modules.

First claim

That which is claimed:

1. A riding lawn mower comprising:
a frame;
a cutting deck operably attached to the frame and comprising one or more cutting blades;
an operator station operably attached to the frame and configured to support an operator during operation of the riding lawn mower;
wheels operably attached to the frame;
steering controls for directing at least one of the wheels;
a battery;
an axle configured to turn at least one of the wheels;
one or more engines or motors operably attached to the frame and configured to provide power to rotate the axle and the one or more cutting blades;
a control module for programmably controlling electrical operations of the riding lawn mower;
a plurality of transceiver modules separate from the control module, the transceiver modules being operably connected between the control module and respective devices of the riding lawn mower so as to communicate data between the respective devices and the control module; and
a wiring system comprising wires that electrically connect the transceiver modules with the control module, wherein the wiring system comprises:
a data bus comprising a data wire that transmits data and power between the control module and at least one of the transceiver modules, the data wire being configured to be attached to the frame of the riding lawn mower,

wherein the transceiver modules are connected to the data wire in parallel.

2. The riding lawn mower of claim 1 , wherein the wiring system comprises:
a power wire that provides electrical power from the battery to at least one of the transceiver modules.

3. The riding lawn mower of claim 1 , wherein each transceiver module comprises a switch and a transceiver configured to receive a request from the control module and to communicate data regarding status of the switch back to the control module.

4. The riding lawn mower of claim 1 , wherein each transceiver is physically separate from the control module so that at least one transceiver is remote from the control module.

5. The riding lawn mower of claim 1 , wherein the control module is programmable so as to send requests to the transceiver modules and to perform predetermined functions based on responses to the requests.

6. The riding lawn mower of claim 5 , wherein the requests comprise requests for status information of devices attached with the transceiver modules.

7. The riding lawn mower of claim 6 ,
wherein each transceiver module comprises a unique identifier,
wherein each request comprises instructions and a request identifier which matches the unique identifier of one of the transceiver modules, and
wherein in response to the request identifier matching the unique identifier of a transceiver module, the transceiver module executes the instructions in the request.

8. The riding lawn mower of claim 7 , wherein the instructions comprise instructions to obtain status information of a device associated with the transceiver module.

9. The riding lawn mower of claim 1 , wherein at least one of the transceiver modules comprises a sensor to detect a predetermined trigger.

10. The riding lawn mower of claim 1 , further comprising a wireless communications module that is configured to wirelessly communicate information to a mobile communications device.

11. The riding lawn mower of claim 10 , wherein the information comprises diagnostic information specific to operational parts of the riding lawn mower.

12. The riding lawn mower of claim 10 , wherein wirelessly communicating the information occurs over a short range wireless communication network between the wireless communications module of the riding lawn mower and the mobile communications device.

13. The riding lawn mower of claim 10 , wherein the wireless communications module is configured to receive an instruction from the mobile communications device to control one or more operational parts of the riding lawn mower.

14. The riding lawn mower of claim 13 , wherein the one or more operational parts comprise the engine or head lights.

15. A riding lawn care vehicle comprising:
a frame;
a cutting deck operably attached to an underside portion of the frame;
an operator seat operably attached to the frame;
wheels operably attached to the frame;
steering controls for directing at least one of the wheels;
a control module for controlling electrical operations of the riding lawn care vehicle;
a plurality of transceiver modules being operably connected with respective devices of the riding lawn care vehicle so as to communicate data to and from the respective devices to the control module, each transceiver module comprising:
memory comprising a transceiver identifier;
a transceiver configured to receive a request from the control module, the request comprising a request identifier and an instruction; and
a processor configured to:
receive the request identifier from the transceiver;
retrieve, from the memory, the transceiver identifier of the transceiver module;
compare the request identifier of the request with the transceiver identifier of the transceiver module to determine if the transceiver identifier and the request identifier match; and
in response to the transceiver identifier and the request identifier matching, execute the instruction; and

a wiring system comprising wires that electrically connect at least one transceiver module of the plurality of transceiver modules with the control module, wherein the wiring system comprises:
a data bus comprising a data wire that transmits data between the control module and the at least one transceiver module.

16. The riding lawn care vehicle of claim 15 , wherein the control module is programmable so as to send the request to the at least one transceiver module and to perform predetermined functions based on a response to the request.

17. The riding lawn care vehicle of claim 15 , wherein the control module transmits the request wirelessly from the control module to a second transceiver module of the plurality of transceiver modules.

18. The riding lawn care vehicle of claim 15 , wherein the plurality of transceiver modules are connected in parallel to the wiring system.

19. The riding lawn care vehicle of claim 18 , wherein the wiring system further comprises:
a power wire that provides electrical power to the plurality of transceiver modules; and
wherein the plurality of transceiver modules are connected to the power wire in parallel and are also connected to the data bus in parallel.

20. A riding lawn care vehicle comprising:
a frame;
a cutting deck operably attached to an underside portion of the frame;
wheels operably attached to the frame;
steering controls for directing at least one of the wheels;
a wiring system;
