Abstract
An apparatus for controlling a vehicle includes a sensor to determine whether to transmit a signal related to a recharging operation for a low voltage battery. The apparatus also includes a processor configured to determine whether to wake up, based on whether the signal related to the recharging operation for the low voltage battery is received and to determine whether to perform the recharging operation for the low voltage battery, in response to the signal related to the recharging operation for the low voltage battery when waking up.
Claims20
An apparatus for controlling a vehicle, the apparatus comprising:
- a sensor configured to
- acquire a state of charge (SOC) of a low voltage battery,
- acquire an SOC of a high voltage battery when an IGN3 power is turned off,
- compare the SOC of the high voltage battery with a second threshold value, when the SOC of the low voltage battery is equal to or less than a first threshold value, and a decrement of the low voltage battery exceeds a reference value, and
- transmit a signal related to a recharging operation for the low voltage battery based on a comparison result;
- and
- a processor configured to
- wake up, based on the signal related to the recharging operation for the low voltage battery being received, and
- control to perform the recharging operation for the low voltage battery, in response to the signal related to the recharging operation for the low voltage battery when waking up.
