FIG. 1 shows an embodiment of the present invention. In the figure, reference numeral 10 denotes a sensor group installed in each part of the vehicle.
The sensors include, for example, an engine start / stop sensor 10A linked to a key switch for starting, a door sensor 10B for detecting the opening / closing status of a door for getting on and off, a seat belt attaching / detaching sensor 10C for detecting attachment / detachment of a seat belt, and a switch for controlling a direction indicator. Direction indicator sensor 1 that operates in conjunction with
0D, a brake sensor 10E for detecting the depression of the brake pedal, a stop lamp disconnection detection sensor 10F for detecting whether or not current flows to the stop lamp when the brake pedal is depressed, and a headlight when the headlight is turned on. A headlight disconnection detection sensor 10G that detects whether a current has flowed, a fuel sensor 10H that detects that the remaining amount of fuel is low, and the like can be considered.

A detection signal detected by the sensor group 10 is input to an input port 11. The input port 11 has a plurality of input terminals 11A to 11N.
The timing of reading is defined for each 1N, and a sensor connected to which input terminal outputs a detection signal is identified based on a difference in reading timing. Reference numeral 12 denotes a microcomputer that executes this identification, control for designating a read area of the audio memory 13, and the like.

Reference numeral 13 denotes a voice memory which has a plurality of storage areas 13A to 13N and in which notes to be conveyed to the driver in these storage areas 13A to 13N are stored as voice data. Reference numeral 14 denotes a DA converter, and 15 denotes a loudspeaker. The loudspeaker 15 includes an amplifier 15A and a speaker 15B, as is well known. The microcomputer 12 has input terminals 11A to 11N of the input port 11.
Is read at a predetermined timing, and the input terminal to which the detection signal is input is identified based on the timing at which the detection signal was read.

The voice memory 13 has storage areas 13A to 13N of the number corresponding to the number of the input terminals 11A to 11N provided in the input port 11, or more than that, and notes on each of the storage areas 13A to 13N. Is stored as audio data. For example, when an engine start / stop sensor 10A that operates in conjunction with a key switch is connected to the input terminal 11A of the input port 11, when the key switch is turned on to start the engine, for example, H logic is input to the input terminal 11A. Is done. The microcomputer 12 knows that the engine has been started by inputting the H logic. Accordingly, in this state, for example, the microcomputer 12 accesses the storage area 13A of the audio memory 13, reads out the audio data stored in the storage area 13A, DA-converts the audio data with the DA converter 14, and outputs the audio signal to the loudspeaker 15. For example, broadcast "Please confirm the safety around you and start."

At the same time, the microcomputer 12 monitors whether the input terminals 11B and 11C are inverted to H logic. That is, the example shown in FIG. 1 shows an example in which the door sensor 10B is connected to the input terminal 11B, and the seat belt attachment / detachment sensor 11C is connected to the input terminal 11C. If the input terminal 11B and the input terminal 11C remain at the L level when the engine is started, the microcomputer 12 determines that the door is not completely closed and determines that the seat belt is not fastened. .

Therefore, the microcomputer 12 accesses the storage area 13A, 13B and 13C of the audio memory 13 in order, and reads out the audio data stored therein. The audio data is DA-converted by the DA converter 14 to be converted into an analog signal, and is broadcast by the loudspeaker 15 as audio. In the storage area 13B, for example, "the door is a half door"
By storing, for example, "Please fasten your seat belt" in the storage area 13C, the loudspeaker 15 starts "Please confirm the safety around you and start. The door is a half door. Please fasten your seat belt. " This broadcast is input terminals 11B and 1
It continues until 1C is inverted to H logic.

When the input terminal 11B is inverted to H logic, the microcomputer 12 accesses the storage areas 13A and 13C of the audio memory 12. Therefore, the broadcast content is changed to "Please confirm the safety of the surroundings and transmit. Please fasten your seat belt." H to input terminal 11C

Access E. In this storage area, for example, voice data of "Let's put gear and apply the side brake surely, be careful of pedestrians and bicycles when getting off" is stored. Therefore, the audio data is read out and broadcast from the loudspeaker 15.

A direction indicator detection sensor 10F is connected to the input terminal 11F. When the direction indicator (turn signal) is directed rightward, the direction indication detection sensor 10F inputs H logic to the input terminal 11F. With this input, the microcomputer 12 confirms that the input terminal 11A is at the H logic, determines that the direction indicator has been instructed to the right during traveling, accesses the storage area 13F of the voice memory 13, and For example, the voice data of “Right turn signal has been instructed. Turn right with caution” stored in the 13F is read out, and this is broadcast from the loudspeaker 5 as voice.

A direction indication detecting sensor 1 is provided at an input terminal 11G.
0G is connected. When the direction indicator is directed leftward, the direction indication detection sensor 10G outputs H to the input terminal 11G.
Enter logic. If the input terminal 11G and the input terminal 11A are both at the H logic, the microcomputer 12 determines that the vehicle is going to turn left during traveling.
The third storage area 13G is accessed. This storage area 13

For example, a stop lamp disconnection detection sensor 10H is connected to the input terminal 11H. The stop lamp disconnection detection sensor 10H inputs H logic to the input terminal 11H when the brake lamp is depressed and no current flows through the stop lamp. For this purpose, the stop lamp disconnection detection sensor 10H is configured by a combination of a current detection sensor and a voltage detection sensor. When the current detection sensor passes a current through the stop lamp, the detection voltage of the voltage inspection sensor is maintained at L logic, When the detection sensor detects that no current has flowed through the stop lamp, an H logic voltage (voltage applied to the lamp) output from the voltage detection sensor may be output and applied to the input terminal 11H.
