Abstract
An engine speed control apparatus employs a governor responsive to predetermined control input signals for controlling engine speed. An accelerator sensor produces an accelerator control input signal corresponding to the position of an accelerator. A mode selector selects one of a governor mode and a throttle mode, and produces one of a governor mode control input signal and a throttle mode control input signal corresponding to the mode selected. The governor is responsive to the governor mode control input signal for permitting the selection of an upper limit of engine speed within a predetermined range of speeds and thereafter for controlling the engine speed to maintain the engine at this upper limit when the accelerator control signal corresponds to a maximum accelerator position. The governor is responsive to the throttle mode control input signal for permitting the selection of a lower limit of engine speed within a predetermined range and for thereafter controlling the engine speed to maintain the engine at this lower limit of engine speed when the accelerator control signal corresponds to a minimum accelerator position.
