Appeal No. 2002-1641
Application No. 09/276,213
controller will determine an increasing slip state or a
decreasing slip state during ABS and ASR modes, which is inherent
in ABS and ASR systems so as to control the elements of a brake
system accordingly." In addition, the examiner notes that
Schaefer discloses that the wheel vibration mentioned therein is
ascertained during either an ABS or ASR mode, thus leading the
examiner to conclude that a braking force in Schaefer is
influenced as a function of the ascertained tendency.
At least with regard to the independent claims, the examiner
further posits on page 4 of the answer that
[t]he disclosure of Schaefer et al. merely fails to
specify the details of ascertaining the tendency of the
slippage by comparing a subsequent slippage value to a
previous slippage value. Ghoneim teaches an ASR system
in which a tendency or trend of a wheel slippage, such
as an increasing or decreasing wheel slip, is
ascertained by comparing subsequent slippage values to
previous slippage values, see column 9, lines 56-58.
It would have been obvious to one of ordinary skill in
the art at the time of the invention to have provided
the system of Schaefer et al. with a means of
ascertaining the tendency of a characteristic of the
slippage by comparing subsequent slippage values to
previous slippage values as taught by Ghoneim, this
would have provided the system of Schaefer et al. with
the capability to react to a state of increasing
slippage or a state of decreasing slippage during the
ABS or ASR mode.
