Abstract
An ISG system may include a shift stage sensing unit that senses a shift stage of a transmission, a parking sensing unit that senses a driver's intension of parking by recognizing at least one of whether a vehicle enters a parking lot and whether a parking assistant system may be operated, and an ISG controller that stops an idle-stop of an engine when the shift stage of the shift stage sensing unit may be at a reverse stage or the parking sensing unit senses the driver's intension of parking.
Claims8
An ISG system, comprising:
- a shift stage sensing unit that senses a shift stage of a transmission;
- a parking sensing unit that senses a driver's intension of parking by recognizing at least one of whether a vehicle enters a parking lot and whether a parking assistant system is operated;
- and
- an ISG controller that stops an idle-stop of an engine when the shift stage of the shift stage sensing unit is at a reverse stage and the parking sensing unit senses the driver's intension of parking.
1 more element
A control method of an ISG system, comprising:
- a first step of checking whether a shift stage is at a reverse stage;
- a second step of sensing a driver's intension of parking;
- a third step of stopping an idle-stop of an engine when the shift stage is at the reverse stage and the driver's intension of parking is sensed under an idle-stop condition of the engine;
- a fourth step of checking whether a stop-removing condition is satisfied after the third step;
- and
- a fifth step of idle-stopping or starting the engine, depending on that the idle-stop condition is satisfied or the restart condition is satisfied when the stop-removing condition is satisfied.
