PROBLEM TO BE SOLVED: To provide a vehicular control device in which no expensive memory is used for a slave server, a communication system is inexpensive, and the display corresponding to the mode before the instantaneous interruption is given if a power supply is instantaneously interrupted. SOLUTION: A slave server 2 having a function switch 4, a display unit 5, and a control unit 10, a master server 1 having a function status memory 8 and a main control unit 6, and a bus line 3 to connect the servers 1, 2 are arranged in a vehicle, and the master server 1 transmits the requested signal to the slave server 2 via the bus line 3 at a predetermined time interval. When the slave server 2 receives the requested signal, the signal to indicate the switches status is transmitted via the bus line 3. The main control unit 6 of the master server 1 transmits the display status signal matched with the data of the function status memory 8 to the slave server 2 via the bus line at a predetermined time interval.
