To enable the charging of a power storage device at the time of a power shortage.SOLUTION: A vehicular control device is mounted on a vehicle including: a power storage device; a drive device driven by power from the power storage device; a system main relay attached to a power line between the power storage device and the drive device; and a charging circuit connected to the drive device side, relative to the system main relay, of the power line. At the time of a power shortage in the power storage device, the vehicular control device turns off the system main relay and prohibits the restart of a system. When the charging of the power storage device using the charging circuit is requested, the vehicular control device permits the system main relay to be turned on.SELECTED DRAWING: Figure 2 【課題】電欠時に蓄電装置を充電できるようにする。【解決手段】蓄電装置と、蓄電装置からの電力により駆動する駆動装置と、蓄電装置と駆動装置との間の電力ラインに取り付けられたシステムメインリレーと、電力ラインのシステムメインリレーより駆動装置側に接続された充電回路と、を備える車両に搭載された車両用制御装置は、蓄電装置の電欠時にはシステムメインリレーをオフとすると共にシステム再起動を禁止する。そして、充電回路を用いた蓄電装置の充電が要求されたときには、システムメインリレーのオンを許可する。【選択図】図２
