Abstract
An apparatus for managing power of a vehicle includes a processor that controls a bypass path for bypassing an input power or a boosting path for boosting the input power corresponding to an idle mode signal, a booster that boosts the input power corresponding to a driving signal to generate an output power, a control circuit that selectively supplies a power for operating the booster corresponding to an output signal of the processor in a boost mode, and a pulse width control circuit that controls a duty of the driving signal corresponding to an output signal of the control circuit.
Claims19
An apparatus for managing power of a vehicle, the apparatus comprising:
- a processor configured to control a bypass path for bypassing an input power or a boosting path for boosting the input power corresponding to an idle mode signal;
- a booster configured to boost the input power corresponding to a driving signal to generate an output power;
- a control circuit configured to selectively supply a power for operating the booster corresponding to an output signal of the processor in a boost mode;
- and
- a pulse width control circuit configured to control a duty of the driving signal corresponding to an output signal of the control circuit,
- wherein the control circuit includes:
- a driving controller selectively operated corresponding to a control signal applied from the processor;
- a driving device driven corresponding to an output signal of the driving controller to selectively supply a boost voltage corresponding to an output voltage;
- and
- a resistance dividing device configured to resistance-divide the boost voltage to generate a divided voltage.
A method of managing power of a vehicle, the method comprising:
- supplying an output power to a load of the vehicle corresponding to an input power in a bypass mode;
- terminating the bypass mode and activating a boost mode when an idle mode signal is activated and the input power is less than a specified voltage;
- and
- terminating the boost mode and activating the bypass mode when the input power is equal to or higher than the specified voltage,
- wherein the supplying an output power to a load of the vehicle corresponding to an input power in a bypass mode includes:
- selectively operating corresponding to a control signal;
- selectively supplying a boost voltage corresponding to an output voltage;
- and
- resistance-dividing the boost voltage to generate a divided voltage.
