Multi-function engine control and input system

1. An engine control and input system for a device having a tool driven by an engine, comprising:

an input and control module having multiple inputs and a controller responsive to actuation of the inputs to permit user control of at least one engine operating parameter by user actuation of the inputs, wherein the inputs relate to two or more of changing engine speed, starting the engine, causing the engine to drive the tool, turning on a light, actuating a heater or warmer or stopping engine operation; and

a switch having a first state and a second state, and wherein the controller is responsive to the state of the switch to prevent operation of at least one of the one or more inputs if the switch is in the first state and to allow operation of at least one of the one or more inputs if the switch is in the second state.

2. The system of claim 1 which includes a touch screen display that displays icons to the user relating to the inputs and the at least one engine operating parameter, and wherein the touch screen display is responsive to the user selecting one of the inputs by touching an associated one of the icons provided by the display.

3. The system of claim 1 wherein: a) the device includes a seat and the switch is associated with the seat so that the switch is in the first state when the user is not seated in the seat and the switch is in the second state when the user is seated in the seat, or b) the device includes a brake and the switch is associated with the brake so that the switch is in the first state when the brake is not applied and the switch is in the second state when the brake is applied.

4. The system of claim 1 wherein the device includes two or more engine operating modes and wherein the inputs permit a user to select one of the engine operating modes wherein the engine operating modes include at least one of a lower speed engine operating mode and a higher speed engine operating mode, or the engine operating modes include at least one of a more responsive engine operating mode and a less responsive engine operating mode.

5. The system of claim 4 which also includes memory in which is stored engine operating parameters associated with the engine operating modes, and wherein the controller is coupled to the memory and the controller is responsive to implement the engine operating parameters associated with a selected one of the engine operating modes.

6. The system of claim 2 wherein the controller commands the display to show one or more of throttle position, engine speed, engine temperature, engine hours, air temperature, oil pressure, oil temperature and at least one fault condition or warning message to the user.

7. The system of claim 1 which also includes a power source and wherein operation of at least one input is prevented by not providing power to the controller until the switch is in the second state.

8. The system of claim 7 wherein the controller is coupled to the power source and the controller is maintained in a low power mode until the switch is in the second state wherein the controller wakes up and enables at least one input for actuation.

9. The system of claim 1 which also includes a Bluetooth module to permit wireless control of the module via a Bluetooth coupled device.

10. The system of claim 9 wherein the Bluetooth module is received in an enclosure having an opening through which the wireless signals between the Bluetooth module and the coupled device are more readily passed compared to other portions of the enclosure.

11. The system of claim 10 wherein the enclosure is defined by a housing having an open side or by signal attenuating material surrounding at least a portion of an antenna of the Bluetooth module.

12. The system of claim 2 wherein the display includes touch sensitive areas that permit a user to select from different options each associated with a separate one of the touch sensitive areas, and wherein at least one touch sensitive area may be used to provide two different options to a user with a first option available to permit initial starting of the engine and a second option available after the engine has been started.

13. The system of claim 12 wherein the first option includes an input via which at least part of an access code may be entered, wherein entry of an incorrect access code causes the controller to prevent starting of the engine and wherein the controller permits starting of the engine upon entry of a correct access code, and wherein the second option includes an input via which an engine operating condition can be modified.

14. A device, comprising:

an engine including a throttle and an electronic throttle control that actuates the throttle and changes the engine speed;

a tool driven by the engine;

an input and control module having multiple inputs and a controller, wherein the controller is coupled to the throttle control and is responsive to actuation of the inputs to permit user control of multiple engine operating parameter by user actuation of the inputs, wherein the inputs relate to two or more of changing engine speed, starting the engine, causing the engine to drive the tool, turning on a light, actuating a heater or warmer or stopping engine operation; and

a switch having a first state and a second state, and wherein the controller is responsive to the state of the switch to prevent operation of at least one of the one or more inputs if the switch is in the first state and to allow operation of at least one of the one or more inputs if the switch is in the second state.

15. The device of claim 14 which also includes memory with which the controller is communicated and wherein the memory includes information relating to two or more engine operating modes, and the inputs permit a user to select one of the engine operating modes.

16. The system of claim 15 wherein the engine operating modes include at least one of a lower speed engine operating mode and a higher speed engine operating mode, and wherein the memory includes information relating to control of the throttle control for both operating modes, or wherein the engine operating modes include at least one of a more responsive engine operating mode and a less responsive engine operating mode, and wherein the memory includes information relating to control of the throttle control for both operating modes.

17. The system of claim 16 wherein the information relating to control of the throttle control includes information relating to a desired engine speed for multiple operating conditions of both operating modes.

18. The system of claim 17 wherein the multiple operating conditions include a first condition when the tool is not driven by the engine and a second condition when the tool is driven by the engine.

19. The system of claim 17 which also comprises an engine controller and wherein the engine controller provides a signal to the input and control module controller that is indicative of engine speed and wherein the input and control module controller controls the throttle control as a function of the engine speed compared to a desired engine speed for the selected engine operating mode.

20. The system of claim 18 wherein the controller actuates the throttle control to reduce engine speed prior to changing from the first condition to the second condition to reduce a torque impulse when the tool is initially driven by the engine.

21. The system of claim 18 wherein the desired engine speed is different for the first condition than for the second condition.
