Abstract
A power supply device is mounted in a vehicle capable of starting an engine with power supplied from a battery, and includes a booster configured to boost voltage supplied from the battery, a detecting unit configured to detect an engine start, a counting unit configured to count an engine start count based on the detecting unit, and a control unit configured to control the booster. The control unit outputs a control signal to permit the booster to boost the voltage in response to the engine start when the engine start count counted by the counting unit within a timer period does not exceed an allowable number of times.
Claims16
A power supply device to be mounted in a vehicle configured to start an engine with power supplied from a battery, comprising:
- a boosting circuit configured to boost voltage supplied from the battery;
- a detecting unit configured to detect a start of the engine;
- a counting unit configured to count an engine start count based on the detecting unit;
- and
- a control unit configured to control the boosting circuit,
- wherein the control unit permits the boosting circuit to boost the voltage in response to the engine start detected by the detecting unit when the engine start count counted by the counting unit for a predetermined period does not exceed a first allowable number of times.
A method for controlling a boosting circuit provided in a power supply device mounted in a vehicle configured to start an engine with power supplied from a battery, the method comprising:
- detecting a start of the engine;
- counting an engine start count that is detected;
- and
- permitting the boosting circuit to boost voltage in response to detection of the engine start when the engine start count counted for a predetermined period does not exceed a first allowable number of times.
A non-transitory machine readable storage medium having stored thereon a program for controlling a boosting circuit provided in a power supply device mounted in a vehicle configured to start an engine with power supplied from a battery, the program comprising:
- detecting a start of the engine;
- counting an engine start count that is detected;
- and
- permitting the boosting circuit to boost voltage in response to detection of the engine start when the engine start count counted for a predetermined period does not exceed a first allowable number of times.
