Appeal No. 2006-0945
Application No. 10/245,888
Claim 4
Appellants argue that Narita fails to show:
slip controlled state of the torque converter, in which the slip rotation between the
input and output elements of the torque converter is controlled to be a slip rotation
other than zero
and
coasting lockup capacity [that] is increased corresponding to increase in operation
load of the air conditioner
[See brief at p. 8].
As the examiner has indicated, Narita shows:
the coasting drive can be alternatively judged in accordance with an idle switch
which is turned ON when releasing the accelerator pedal at the step 25 as the
coasting drive detecting means [emphasis added; See Narita col. 9, l. 2-5].
and
When the vehicle speed V is judged to deviate from the range between the
quantize upper limit value VU and the quantize lower limit value VL at the
step 50, the lock-up clutch application capacity correction value for the
coasting drive used for retrieval at the step 45 is corrected by the learning
control on the basis of ΔNmax and ΔNmin at the step 56. This learning control is as
shown in FIG. 7, and the learning control flag FLAG is first reset to 0 at the step
57, and thereafter the judgment is made upon whether ΔNmax is larger than a
minute slip amount predetermined value β or whether ΔNmin is smaller than a
further minute slip amount predetermined value γ at the step 58. Here, the
further minute slip amount predetermined value γ is not 0 and set as a
minute predetermined value which is close to 0 limitlessly because the
judgment of 0 is impossible. Further, the minute slip amount predetermined
value β is set because the hysteresis for avoiding hunting of the control must be
set [emphasis added; See Narita col. 11, l. 10-26].
and
The driving load of the air conditioner is added to the retrieved reverse driving
torque T, and the control shown in FIG. 9 is performed at the time of ON
[emphasis added; See Narita col. 12, l. 47-49].
