continuously repeating the above sequence of steps at uniform intervals
of time to effect changes in the target input shaft speed value in response to
changes in the vehicle acceleration.
32. (additions underlined and deletions bracketed vis-a-vis issued claim 14)
A method of controlling a continuously variable transmission for use with
an automotive vehicle including an accelerator pedal, the transmission having an
input and output shaft, the transmission being operable at a variable speed ratio
for transmitting a drive from the input shaft to the output shaft, the method
comprising the steps of:
sensing vehicle operating conditions including vehicle speed
[deceleration];
producing a released accelerator pedal indicative signal when the
accelerator pedal is released;
determining a vehicle deceleration;
calculating a target value for the speed of rotation of the input shaft based
on the sensed vehicle operating conditions;
calculating a correction factor based on the determined [sensed] vehicle
deceleration when the determined [sensed] vehicle acceleration exceeds a first
threshold value in the presence of the released accelerator pedal indicative
signal;
subtracting the correction factor to the target input shaft speed value to
decrease the target input shaft speed value;
controlling the speed ratio to bring the input shaft speed into coincidence
with the decreased target value; and
continuously repeating the above sequence of steps at uniform intervals
of time to effect changes in the target input shaft speed value in response to
changes in the vehicle deceleration.
Thus, this reissue application seeks to enlarge the scope of the issued claims of
the patent, and was properly filed within two years from the grant of the patent, as
provided by the fourth paragraph of 35 U.S.C. § 251. However, the examiner considers
claims 19 to 36 to be unpatentable under 35 U.S.C. § 251 because they improperly
