respectively. Sensor 110 is a lateral acceleration sensor for
monitoring lateral acceleration exerted on the vehicle, and
sensor 112 is a longitudinal acceleration sensor for
monitoring longitudinal acceleration exerted on the vehicle
(column 9, lines 36-43). The gain of gain-controlled
amplifiers 116 and 120 is also dependent on a signal derived
from sensor 108 for providing a signal representative of
vehicle speed. The signals S and S provided by amplifiersX Y
120 and 116, respectively, are added to or
subtracted from the signals S -S provided by the respective
ZFL ZRR
fixed-gain amplifiers 124 -124 in a manner described at
FL RR
column 10, line 29 through column 11, line 60. The end result
is a set of coordinated signals S -S that effectively control
FL RR
vehicle pitch.
From the above, it is apparent that not only does Akatsu
fail to teach a processing means for judging road roughness
based on an evaluation of upward and downward acceleration, or
upward and downward velocity derived therefrom, it also fails
