Appeal No. 2002-2151
Application No. 09/342,234
examiner in this appeal is whether or not Weiss discloses a
determining device in each of the plurality of slave apparatuses
for determining whether the current apparatus state stored in the
memory of the slave apparatus coincides with the system state
command that is periodically received from the master apparatus.
The Weiss patent discloses a computer/bus message system for
a vehicle drive control system, wherein the drive control system
includes a process computer (24) which includes parallel and
independently operating function modules (26-36) for controlling
specific vehicle functions based on inputs from operator
controlled devices (10-20). The process computer (24) regularly
transmits target value signals over the system bus (40) in the
form of a combined message to controllers (50-64), such that each
controller connected to the system bus basically "receives all
communications and detects which parts of the communication are
intended for it and evaluates these" (col. 3, lines 17-20). It
is further noted that in case of a failure of signals the
controller continues to operate with the information received
previously. The individual controllers (50-64) control a
respective actuator, e.g., the steering controller (52) controls
the steering actuator (72), while the brake controller (58)
