Abstract

A vehicle battery controller includes a sensor configured to acquire information on a subordinate battery configured to back up a main battery during autonomous driving, a DDC provided between the main battery and the subordinate battery, a switching circuit configured to switch a connection state of the subordinate battery between a connection state for manual driving and a connection state for the autonomous driving, and an electronic control unit configured to control charging and discharging of the subordinate battery by controlling the DDC and the switching circuit based on the information acquired by the sensor. The electronic control unit permits the autonomous driving when determination is made, through first battery control, that the subordinate battery can output backup power. The electronic control unit determines whether the subordinate battery can output the backup power by executing second battery control having higher accuracy than that of the first battery control.
