  • a plurality of sensors each of which detects a specified condition of one of a plurality of items of a vehicle which are to be detected and generates a detection signal;

    encoder means responsive to said detection signal to generate a code signal indicative of corresponding one of said items and an interruption operation command signal;

    voice generating means including means storing warning voice data corresponding to each of said items to be detected to generate a warning voice;

    externally-operated command means for establishing a plurality of ranks of different priorities to classify said items correspondingly and selecting one of said ranks to inhibit said voice generating means from generating warning voices corresponding to particular one or more of said ranks; and

    computing means responsive to said encoder means and said externally-operated means to control said voice generating means to inhibit the generation of warning voices corresponding to one or more of said ranks lower in priority than said selected rank, said computing means including first memory means responsive to said interruption operation command signal and said code signal to store said code signal, means for determining one of said ranks corresponding to said code signal, second memory means for storing said determined rank, comparing means for comparing said stored rank with said rank selected by said externally-operated command means to cause said voice generating means to generate a warning voice when said stored rank is not lower in priority than said selected rank, and counter means whereby after the generation of said warning voice a code signal corresponding to another higher-priority one of said ranks is read from said first memory means to cause the generation of another warning voice.
