REMOTE CONTROLLER FOR ON-VEHICLE EQUIPMENT

Japanese Patent JP3222924

B2

PURPOSE: To utilize an extension telephone set or the like on market and to surely inform an operator of the result of remote control by sending an output of a slave set from the slave set based on the state of an on-vehicle installation or the like controlled through demodulation or voice recognition of the output of the slave set.
CONSTITUTION: A master set or a slave set into which 4-digits of password are entered by a ten-key sends a 4-digit DTMF signal. The DTMF signal energizes an extension speaker of a slave set 1 and is inputted and decoded by a DTMF receiver 21 via an acoustic coupler 20. When a decoded signal is coincident with a password stored in advance in a password number discrimination circuit 22, a contact of a relay section 23 is closed by an output of a password discrimination circuit 22 to drive a cell motor. When an engine revolution detection circuit 24 detects stable revolution of an engine, a DTMF generator 25 outputs a predetermined DTMF signal to an extension microphone of the slave set 1 via the acoustic coupler 20 and the sound is sent to the master set or the slave set near which the operator is resident.
