Abstract: A vehicle power supply control device includes an interlock circuit configured to detect opening of a case of an electronic device, an interlock detecting unit configured to detect the opening based on an input signal from the interlock circuit, a vehicle speed detecting unit, and a power supply control unit configured to cut off supply of electric power from an onboard battery to the electronic device when a duration of a state in which a vehicle speed is 0 exceeds a predetermined stoppage time after the opening of the case has been detected.

Abstract: A battery management device includes: a first switch state acquisition unit configured to acquire the state of an ignition switch; a determination unit configured to determine to perform correction control for correcting an error in the state of charge (SOC) of the battery when the ignition switch is operated from ON to OFF; a correction control unit configured to perform the correction control of the SOC of the battery when it is determined that the correction control is to be performed; and a second switch state acquisition unit configured to acquire the state of a cancel switch for canceling the execution of the correction control. When the ignition switch is operated from ON to OFF while the cancel switch is ON, the determination unit determines that the correction control is not to be performed.

Abstract: An operating mode control device includes a travel driving force information acquisition unit configured to acquire a time-series travel driving force when traveling on a travel route; a vehicle speed information acquisition unit configured to acquire a time-series vehicle speed when traveling on the travel route; a motor operation estimation unit configured to estimate a time-series torque and rotation speed of the motor on the basis of a time-series travel driving force and vehicle speed; an efficiency calculation unit configured to acquire a time-series efficiency value of each operating mode on the basis of the time-series torque and rotation speed and calculate a total efficiency value; an operating mode determination unit configured to determine the operating mode having the highest total efficiency value as a default operating mode; and an operation control unit configured to control an operation by the default operating mode.
