(e.g., a signal generated by a vehicle safety system upon
detection of a safety condition, wherein the safety signal
relates to a safe operation of the motor vehicle), we find such
arguments unpersuasive. It is clear from a reading of Katayama's
discussion of the embodiment seen in Figures 1 and 2 (i.e., col.
2, line 45 - col. 5, line 8) that there is provided a system and
method for metering fuel in a motor vehicle wherein that system
controls a driving force (by cutting off fuel supplied to the
fuel injectors) to meet a brake demand to thereby cause the
vehicle to obey the brake demand, particularly in the situation
where the Master Vac (3) seen in Figure 1 ceases to operate
properly. Thus, when the brake fluid pressure P is greater thanB
or equal to a preset value P for a predetermined period ofBSET
time, the system of Katayama decides that a safety condition has
occurred and instructs a fuel-cut signal (safety signal) to be
sent to the control unit (20). In response to the fuel-cut
signal (safety signal), the control unit (20) performs a fuel-cut
function to suspend fuel injection via the injectors (23),
