Appeal No. 2003-0405 Page 12
Application No. 09/635,183
Cikanek's invention relates generally to antiskid braking and traction control for a
vehicle and, more particularly, to a system and method for providing such control in an
electric or hybrid vehicle having a regenerative braking system operatively connected to
an electric traction motor, and a separate hydraulic braking system.
The appellants argue (brief, pp. 11-12; reply brief, p. 4) that Cikanek does not
teach the following:
(1) the processing system executing "a strategy comprising reducing, but not
completely eliminating, the torque that is being applied to the drivetrain as regenerative
braking torque when a wheel-condition-initiated triggering event occurs" as recited in
claim 2;
(2) the processing system executing "a strategy comprising operating the friction brakes
to apply at least some of the reduction in regenerative braking torque as friction brake
torque" as recited in claim 2; and
(3) the step of "reducing, but not completely eliminating, the torque that is being applied
to the drivetrain as regenerative braking torque when a wheel-condition-initiated
triggering event occurs, and operating friction brakes of the vehicle to apply at least
some of the reduction in regenerative braking torque as friction brake torque" as recited
in claim 16.
