Claims Analysis

Total Claims: 7
Claim 1
Independent Claim 116 words
A jolt control system for a drive system including a prime mover provided with manually operable means for controlling output torque of the prime mover, and an automatic transmission, comprising: sensor means for sensing a position of the manually operable output torque controlling means and generating an output signal indicative of said position sensed; means for effecting an output torque alteration control, wherein the output torque of the prime mover is altered, when the automatic transmission undergoes a gear shift operation: and means for detecting a predetermined change in said output signal when the automatic transmission undergoes the gear shift operation and rendering said output torque alteration control effecting means inoperable upon detecting said predetermined change.
Claim 2
Dependent Claim 116 words
A jolt control system for a drive system including a prime mover provided with manually operable means for controlling output torque of the prime mover, and an automatic transmission, comprising: sensor means for sensing a position of the manually operable output torque controlling means and generating an output signal indicative of said position sensed; means for effecting an output torque alteration control, wherein the output torque of the prime mover is altered, when the automatic transmission undergoes a gear shift operation: and means for detecting a predetermined change in said output signal when the automatic transmission undergoes the gear shift operation and rendering said output torque alteration control effecting means inoperable upon detecting said predetermined change.
Claim 3
Dependent Claim 37 words
A jolt control system as claimed in claim 1, wherein said output torque alteration control includes a torque-down control, wherein the output torque of the prime mover is reduced, when the automatic transmission undergoes an upshift operation.
Claim 4
Dependent Claim 34 words
A jolt control system as claimed in claim 1, wherein said sensor means include means for detecting a throttle opening degree of a throttle valve of the prime mover operatively connected to the accelerator.
Claim 5
Dependent Claim 33 words
A jolt control system as claimed in claim 1, wherein said means for detecting said predetermined change in said output signal include a predetermined indicator which is set upon detecting said predetermined change.
Claim 6
Dependent Claim 107 words
A jolt control method for a drive system including a prime mover provided with manually operable means for controlling output torque of the prime mover, and an automatic transmission, comprising: sensing a position of the manually operable output torque controlling means and generating an output signal indicative of said position sensed; effecting an output torque alteration control, wherein the output torque of the prime mover is altered, when the automatic transmission undergoes a gear shift operation: and detecting a predetermined change in said output signal when the automatic transmission undergoes the gear shift operation and rendering said output torque alteration control inoperable upon detecting said predetermined change.
Claim 7
Dependent Claim 107 words
A jolt control method for a drive system including a prime mover provided with manually operable means for controlling output torque of the prime mover, and an automatic transmission, comprising: sensing a position of the manually operable output torque controlling means and generating an output signal indicative of said position sensed; effecting an output torque alteration control, wherein the output torque of the prime mover is altered, when the automatic transmission undergoes a gear shift operation: and detecting a predetermined change in said output signal when the automatic transmission undergoes the gear shift operation and rendering said output torque alteration control inoperable upon detecting said predetermined change.
