PURPOSE:To ensure that check items and abnormal conditions can be checked and informed phonically when a driver and/or passengers get on or off an automobile or when the automobile is running, by provision of detectors for detecting conditions of portions (starting key condition, open-close condition of doors, etc.) and generating output signals indicating the conditions. CONSTITUTION:An operating condition detector group 1 comprises a starting key condition detector contact 1a, door open-close condition detector contact 1b, side brake operating condition detector contact 1c, etc. The detector group 1, a detector 2 for detecting the condition of meters, and contact group 4 of a digital switch are connected to a microprocessor 6 through interfaces 5-1, 5-2, and 5-3 respectively. The microprocessor 6 scans programs in a broadcasting program memory 8 based on the signals from the detectors, selects a predetermined table in a word memory 7, and feeds it to a word data aural signal conversion circuit 9. The aural signal from the circuit 9 is broadcasted into an operator's room through a speaker 3. |
