PROBLEM TO BE SOLVED: To provide a vehicular electric system capable of adequately controlling the OFF operation of closing the power supply when a driver mistakenly turned off a power supply switch operation unit in a vehicle with an SBW vehicle steering device or the like mounted thereon. SOLUTION: The vehicular electric system has a power supply switch 49 to turn on/turn off the power supply for electric/electronic devices of a vehicle having an electric steering device 10 to generate the turning force by motors 22, 24, and a vehicular behavior sensor 17 to detect the behavior state of the vehicle. When the OFF state is generated in the power supply switch, the behavior state of the vehicle is monitored based on the detection signal output from the vehicular behavior sensor, the vehicular stop state is estimated, and the power supply is turned off.
