Abstract
A vehicular power system, which has an operating switch for making the transition among an ON state in which an IG power is ON or a vehicular power source is ON, an ACC state which is different from the ON state and in which an accessory power is ON, and an OFF state in which the vehicular power source and the accessory power are OFF, wherein when the operating switch is operated while a shift lever is in a parking position in the ACC state after the transition from the OFF state, the transition is made from the ACC state to the ON state.
Claims13
A vehicular power system, comprising:
- a vehicular power having an IG power and an accessory power and supplying electricity to a vehicle;
- and
- an operating switch for making the transition among an ON state in which the IG power and the accessory power are both ON, an ACC state which is different from the ON state and in which the accessory power is ON, and an OFF state in which the IG power and the accessory power are OFF,
- wherein a condition for making the transition from the ACC state to a subsequent state varies between the ACC state after the transition from the ON state and the ACC state after the transition from the OFF state, and wherein when the operating switch is operated while a shift position is in a parking range in the ACC state after the transition from the ON state, the condition is to make the transition from the ACC state to the OFF state.
A vehicular power system, which has an operating switch for making the transition among an ON state in which an IG power is ON or a vehicular power source is ON, an ACC state which is different from the ON state and in which an accessory power is ON, and an OFF state in which the IG power, the vehicular power source and the accessory power are OFF, the transition being made from the ON state to the ACC state when the operating switch is operated while a shift lever is in a position other than a parking position during the ON state,
- wherein, when a predetermined operation is detected during the ACC state after the transition from the ON state, the transition is made to the OFF state, and wherein the predetermined operation includes both an operation of changing the shift position to the parking range and an operation of the operating switch, or only the operation of changing the position of the shift lever to the parking position.
A method of controlling a vehicular power system that comprises:
- a vehicular power having an IG power and an accessory power and supplying electricity to a vehicle;
- and an operating switch for making the transition among an ON state in which the IG power and the accessory power are both ON, an ACC state which is different from the ON state and in which the accessory power is ON, and an OFF state in which the IG power and the accessory power are OFF,
- the method comprising:
- determining whether the ACC state is obtained as a result of the transition made from the ON state or from the OFF state;
- and
- changing a condition for making the transition from the ACC state to a subsequent state, on the basis of a result of the determination.
