Alarm device for a vehicle including priority control for plural alarm conditions

摘要

An alarm device for a vehicle comprises sensors for detecting abnormal states of the vehicle, a logic circuit for receiving the outputs of the sensors and producing one or more alarm speech designation signals and an alarm speech generator responsive to the alarm designation signal. The logic circuit includes a priority circuit for determining the order of precedence of the abnormal states represented by the detection signals on the basis of the degree of emergency, so that the alarm speech is concerned with the most emergent alarm when two or more abnormal states are detected simultaneously. The logic circuit may further include a switch circuit for disabling at least one of the detection signals so that a vehicle driver having taken notice of particular alarms is not disturbed by excessive alarming.
