CONTROL APPARATUS AND METHOD FOR VEHICLE

摘要

An ECU executes a program including the steps of: setting a target boost voltage to a maximum value (S102) when a request for changing a sub power supply is made (YES in S100); temporarily increasing discharge electric power of a main power supply and then restricting discharge electric power of the sub power supply before switching (S104); shutting off a gate of a converter on the sub power supply side (S106); performing processing for shutting off an SMR corresponding to the sub power supply before switching (S108); connecting an SMR corresponding to a sub power supply after switching (S114) when an absolute value of a current IL(2) is equal to or lower than a predetermined value Ia (YES in S110); canceling shut-off of the gate of the converter on the sub power supply side (S116); canceling temporary increase in discharge electric power of the main power supply and restriction of discharge electric power of the sub power supply (S118); and canceling the setting of the maximum value as the target boost voltage (S120).
