speed ratio for transmitting a drive from the input shaft to the output shaft,
comprising:
means for sensing vehicle operating conditions including vehicle speed
[deceleration];
means for producing a released accelerator pedal indicative signal when
the accelerator pedal is released;
means for calculating a target value for the speed of rotation of the input
shaft based on the sensed vehicle operating conditions;
means for determining a vehicle deceleration;
means for calculating a correction factor per predetermined unit time
based on the determined [sensed] vehicle deceleration when the determined
[sensed] vehicle deceleration exceeds a first threshold value in the presence of
the released accelerator pedal indicative signal;
means for subtracting the correction factor from the target input shaft
speed value to decrease the target input shaft speed value at intervals of the
predetermined unit time; and
means for controlling the speed ratio to bring the input shaft speed into
coincidence with the decreased target value.
28. (additions underlined and deletions bracketed vis-a-vis issued claim 10)
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
[acceleration];
producing a released accelerator pedal indicative signal when the
accelerator pedal is released;
calculating a target value for the speed of rotation of the input shaft based
on the sensed vehicle operating conditions;
determining a vehicle acceleration;
calculating a correction factor based on the determined [sensed] vehicle
acceleration when the determined [sensed] vehicle acceleration exceeds a
threshold value in the presence of the released accelerator pedal indicative
signal;
adding the correction factor to the target input shaft speed value to correct
the target input shaft speed value;
controlling the speed ratio to bring the input shaft speed into coincidence
with the corrected target value; and
