ABSTRACT:
Disclosed is a throttle modulation mechanism (10) disposed between a throttle pedal (36) and a fuel control device (12) for an unshown engine. Mechanism is operable during shifting modes of an unshown transmission driven by the engine to dip and boost fuel delivery to the engine for synchronizing the transmission and/or reducing shifting shocks. Mechanism (10), which is controlled by a transmission logic (14), includes first and second levers (16, 20) interconnected for slaved movement by a torsion spring (22) and a fluid actuated cylinder (30) having pistons (48, 52) respectively operative to dip and boost the throttle in response to logic signals applied to solenoid valves (58, 66). A spring (38) connects to and biases lever 16 toward an idle throttle position for allowing movement of lever (20) relative to lever (16) by actuator (30) during shifting modes of the transmission without changing the force applied to throttle pedal (36) by spring (38).
