Abstract

A throttle modulation mechanism (10) disposed be­ tween a throttle pedal (28) and a fuel control device (12) varies speed and torque of an unshown engine. Mechanism is operable during shifting modes of an unshown transmis­ sion 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 and fluid actuated cylinders (38, 40) which respectively dip and boost the throttle in response to logic signals applied to solenoid valves (50, 64). A transducer (24), mechanically connected to first lever (16), provides an electrical signal representative of throttle pedal position. Torsion spring (22) includes ends (22b, 22c) preloaded toward each other and clamping levers (16, 20 or 106) into a predetermined relationship.
