Riding lawn care vehicle auto idle system

1. A riding lawn care vehicle comprising:

a mobility assembly configured to support the riding lawn care vehicle during movement over ground;

a working assembly configured to perform a working function;

an engine operably coupled to the mobility assembly and the working assembly, the engine comprising a throttle and being configured to selectively provide power to the mobility assembly and the working assembly;

a drive control system configured to control delivery of the power from the engine to the mobility assembly; and

an auto idle assembly comprising a control unit configured to detect predetermined criteria, the predetermined criteria including at least clutch and brake positions of the riding lawn care vehicle,

wherein in response to the control unit detecting the predetermined criteria, the control unit is further configured to automatically provide inputs to the drive control system to cause a shift of the throttle to an idle position.

2. The riding lawn care vehicle of claim 1 , further comprising at least one sensor, wherein the control unit is further configured to monitor a status of the at least one sensor and initiate the shift of the throttle to the idle position based on the status.

3. The riding lawn care vehicle of claim 2 , wherein the at least one sensor is configured to detect incline of the riding lawn care vehicle, and wherein the control unit is configured to initiate the shift of the throttle to the idle position responsive to the incline being greater than a predetermined amount.

4. The riding lawn care vehicle of claim 2 , wherein the at least one sensor is configured to detect proximity of an object to the riding lawn care vehicle, and wherein the control unit is configured to initiate the shift of the throttle to the idle position based on the proximity of the object.

5. The riding lawn care vehicle of claim 2 , wherein the at least one sensor is configured to detect an incoming call to an operator of the riding lawn care vehicle, and wherein the control unit is configured to initiate the shift of the throttle to the idle position responsive to detection of the incoming call.

6. The riding lawn care vehicle of claim 2 , wherein the at least one sensor is configured to detect a full bagging attachment of the riding lawn care vehicle, and wherein the control unit is configured to initiate the shift of the throttle to the idle position responsive to detection of the full bagging attachment.

7. The riding lawn care vehicle of claim 2 , wherein the at least one sensor is configured to detect placement of steering levers of the riding lawn care vehicle in an outboard position, and wherein the control unit is configured to initiate the shift of the throttle to the idle position based on detection of the steering levers placed in the outboard position.

8. The riding lawn care vehicle of claim 2 , wherein the at least one sensor is configured to detect a neutral state of the vehicle, and wherein the control unit is configured to initiate the shift of the throttle to the idle position based on detection of the neutral state for at least a predetermined time.

9. The riding lawn care vehicle of claim 2 , wherein the at least one sensor is configured to detect a deactivation condition, and wherein the control unit is configured to deactivate the auto idle assembly responsive to detection of the deactivation condition.

10. The riding lawn care vehicle of claim 9 , wherein the at least one sensor comprises a proximity sensor.

11. The riding lawn care vehicle of claim 1 , wherein the auto idle assembly is further configured to cause a decoupling of the working assembly from the engine during the shift of the throttle to the idle position.

12. The riding lawn care vehicle of claim 1 , wherein, in response to the detection of the predetermined criteria by the control unit, a solenoid of the auto idle assembly urges mechanical linkages to move a biasing element of a throttle control lever in an idle direction to adjust a governor thereby causing the shift of the throttle to the idle position.

13. The riding lawn care vehicle of claim 1 , wherein the auto idle assembly is enabled after the engine has been running for at least a predetermined period of time.

14. The riding lawn care vehicle of claim 1 , wherein the control unit initiates shifting the throttle to the idle position based on the predetermined criteria being met for at least a predetermined period of time.

15. The riding lawn care vehicle of claim 1 , wherein, in response to a clearing of a detected predetermined criteria, the control unit is configured to cause a restoration of the throttle from the idle position to a previous position.

16. An auto idle assembly of a riding lawn care vehicle, the riding lawn care vehicle further comprising a mobility assembly configured to support the riding lawn care vehicle during movement over ground, a working assembly configured to perform a working function, an engine operably coupled to the mobility assembly and the working assembly and comprising a throttle, and a drive control system configured to control delivery of the power from the engine to the mobility assembly, the engine configured to selectively provide power to the mobility assembly and the working assembly, wherein the auto idle assembly comprises a control unit configured to detect predetermined criteria, the predetermined criteria including at least clutch and brake positions of the riding lawn care vehicle and, in response to the detection of the predetermined criteria, automatically provide inputs to the drive control system to cause a shift of the throttle to an idle position.

17. The auto idle assembly of claim 16 , wherein, in response to the detection of the predetermined criteria, a solenoid of the auto idle assembly urges mechanical linkages to move a biasing element of a throttle control lever in an idle direction to adjust a governor thereby causing the shift of the throttle to the idle position.

18. The auto idle assembly of claim 16 , wherein the auto idle assembly is further configured to cause a decoupling of the working assembly from the engine during the shift of the throttle to the idle position.
