Throttle control response selection system
First Claim
1. A method, comprising:
- operating an internal combustion engine having a throttle control;
governing speed of the engine during said operating in accordance with a first one of a number of different engine speed governing relationships, response to the throttle control being different for each of the different engine speed governing relationships, the throttle control being adjustable by an operator to increase or decrease speed for each of the different engine speed governing relationships;
selecting a second one of the different engine speed governing relationships with an operator-controlled selection device; and
regulating speed of the engine during said operating with the second one of the different engine speed governing relationships after said selecting.

Abstract
A vehicle having an internal combustion engine with a throttle control is disclosed. The throttle control is responsive to a vehicle operator to generate a throttle setting signal to adjust vehicle speed. An operator-controlled input device is also provided to generate a selected signal corresponding to a selected one of a number of predetermined engine control relationships. A controller responds to the selection signal to govern engine operation in accordance with the selected one of the relationships and the throttle setting signal. The throttle control has a different performance characteristic for each of the relationships and is adjustable by the operator to increase or decrease speed for each of the relationships. The relationships may each correspond to a different type of engine governing technique and include different droop characteristics.

7. A method, comprising:
-
operating a vehicle propelled by a prime mover having a throttle control; selecting between at least two speed governing relationships with an selection device, the relationships each having a different droop characteristic to provide a correspondingly different throttle control quality to a throttle control operator, the throttle control being adjustable by the operator to increase or decrease vehicle speed for each of the relationships; and regulating operation of the prime mover with a selected one of the relationships. - View Dependent Claims (8, 9, 10, 11, 12)

13. An apparatus, comprising:
-
a vehicle; an internal combustion engine to power said vehicle; a throttle control responsive to a vehicle operator to generate a throttle setting signal to adjust engine speed; an operator-controlled input device to generate a selection signal corresponding to a selected one of a number of predetermined engine speed governing relationships, one of the relationships corresponding to an all-speed governor and another of the relationships corresponding to a torque governor; a controller responsive to said selection signal to govern engine speed in accordance with said selected one of said relationships and said throttle setting signal; and wherein said throttle control has a different performance characteristic for each of said relationships and is adjustable by the operator to increase or decrease vehicle speed for each of said relationships. - View Dependent Claims (14, 15, 16, 17)
