Abstract
Abnormal conditions of the operating members of an automotive vehicle are detected by a plurality of sensors provided at the operating members. Detection signals of the sensors are fed as input to a plurality of warning issuing devices of the vehicle warning system. A priority sequence judging circuit is connected between the sensors and the warning issuing devices. The priority sequence judging circuit operates when more than one of the sensors detect abnormal conditions simultaneously, determines the degree of importance of the detected signals from the sensors and preferentially provides the most important signals as outputs to the warning issuing devices in accordance with the order of their importance. A check circuit is connected to the warning issuing devices. The check circuit artificially creates the same condition as that obtained when the sensors detect abnormalities to actuate all the warning issuing devices and releases such condition in accordance with a predetermined sequence at predetermined time delays. The warning issuing devices are thereby checked for normal operation in accordance with the sequence.
