manual steering torque and powered steering actuator means for
applying an actuating steering torque to steerable wheels of a
vehicle, means for detecting a lateral dynamic condition of
the vehicle and control means for controlling the actuating
steering torque according to the detected lateral dynamic
condition so that the actuating steering torque is dependent
on a difference between the detected lateral dynamic condition
and a reference lateral dynamic condition computed from a
change rate of the detected lateral dynamic condition.
The examiner’s position is that Yamamoto’s second
embodiment discloses the control means of claim 15 (answer,
page 7). Yamamoto’s second embodiment is shown in Figures 12-
14 and discussed at column 7, line 63 et seq. In this
embodiment, the target steering reaction TA' is determined by
the sum of steering reactions T1', T2' and T3' (col. 8, lines
18-22). Steering reaction T2' = f2'×((-( ), where ( is the
0
detected yaw rate, ( is a computed reference yaw rate
0
response model and f2' is a coefficient obtained from a data
table, e.g., Figure 15(B), using the vehicle speed as the
address (Figure 13 and col. 8, lines 5-8 and 12-18). We agree
