Abstract
Abstract A throttle modulation mechanism (10) is disposed between a throttle pedal (18) and a fuel control device (12) for an unshown engine. Mechanism (10) 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 a lever (16) pivotally connected at one end (16a) to link (28), at the other end (16c) to a throttle dip actuator (20), and in the middle (16b) to the fuel control via a link (30) and to a throttle boost actuator (22) via a piston rod (32). The actuators are positioned by fluid pressure in response to logic signals applied to solenoid valves (24, 26). A second embodiment of the modulation device includes a slotted connector (101a) which negates mechanical and force feedback to the throttle pedal independent of all throttle pedal positions.

Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
141 words
A mechanism adapted to be interposed between an engine throttle pedal and an engine fuel control device for varying fuel delivery to an engine during shifting modes of a transmission driven by the engine, the mechanism comprising; a rigid elongated member having first and third end portions each disposed for pivotal and substantially linear movement and a second portion disposed intermediate the first and third portions and adapted to be connected with the fuel control device for varying fuel delivery in response to said linear movement of either end portion, said first portion adapted to be moved linearly and pivoted about the third portion in response to throttle pedal movement; and actuator means operative during shifting modes of the transmission for linearly moving the third portion without changing the position of the throttle pedal and independent of the throttle pedal position.
Claim 2
Dependent Claim
141 words
A mechanism adapted to be interposed between an engine throttle pedal and an engine fuel control device for varying fuel delivery to an engine during shifting modes of a transmission driven by the engine, the mechanism comprising; a rigid elongated member having first and third end portions each disposed for pivotal and substantially linear movement and a second portion disposed intermediate the first and third portions and adapted to be connected with the fuel control device for varying fuel delivery in response to said linear movement of either end portion, said first portion adapted to be moved linearly and pivoted about the third portion in response to throttle pedal movement; and actuator means operative during shifting modes of the transmission for linearly moving the third portion without changing the position of the throttle pedal and independent of the throttle pedal position.
Claim 3
Dependent Claim
64 words
The mechanism of claim 1, wherein said actuator means comprises a first actuator pivotally connected to said third portion and moveable between first and second positions, said member operative when said actuator is in said first position to pivot about the pivot connection in response to movement of the throttle pedal for increasing and decreasing the fuel flow during nonshifting modes of the transmission.
Claim 4
Dependent Claim
28 words
The mechanism of claim 2, wherein movement of said actuator from said first position toward said second position linearly moves said third portion and decreases the fuel flow.
Claim 5
Dependent Claim
71 words
The mechanism of claim 2, further including a slotted connector adapted for slaved movement with the throttle pedal and wherein said first portion is disposed for sliding and pivotal movement in said slotted connector in response to linear movement of the third portion by said actuator means, thereby providing a lost motion connection between said member and said throttle pedal allowing movement of the member without movement of the throttle pedal.
Claim 6
Dependent Claim
32 words
The mechanism of claim 3, wherein said actuator means further comprises a second actuator operative to move said second portion toward a fuel flow increasing position independent of the throttle pedal position.
Claim 7
Dependent Claim
