Abstract

A method for controlling an ISG system is provided. The method includes obtaining a current vehicle location and determining whether the current vehicle location is within a predetermined distance from a preset location or a traffic sign. When the current vehicle location is within the predetermined distance from the preset location or the traffic sign, an ISG mode of the ISG system is automatically inhibited.

First claim

What is claimed is:

1 . A method of controlling an idle stop and go (ISG) system of a vehicle, comprising:
obtaining a current vehicle location; determining whether the current vehicle location is within a predetermined distance from a preset location or a traffic sign; and automatically inhibiting an ISG mode of the ISG system in response to determining that the current vehicle location is within the predetermined distance from the preset location or the traffic sign.

2 . The method of claim 1 , wherein the determination of whether the current vehicle location is within the predetermined distance from the preset location or the traffic sign is triggered based on engagement of a brake pedal.

3 . The method of claim 1 , further comprising:
continuously monitoring a surrounding of the vehicle to detect the traffic sign.

4 . The method of claim 1 , wherein the preset location is a location stored in a navigation system.

5 . The method of claim 4 , wherein the preset location is a home location or a garage location.

6 . The method of claim 1 , wherein the traffic sign is a stop sign, a yield sign, a pedestrian crossing sign, or the like.

7 . The method of claim 1 , wherein the current vehicle location is detected using a global positioning system.

8 . The method of claim 1 , wherein the traffic sign is detected using a camera mounted on the vehicle.

9 . The method of claim 1 , wherein the ISG mode turns off an engine of the vehicle based on a plurality of conditions.

10 . The method of claim 9 , wherein the conditions include a vehicle speed being detected as 0, an accelerator input being detected as 0, and a brake pedal being engaged.

11 . The method of claim 1 , wherein the current vehicle location, the preset location, and the traffic sign are determined using an advanced driver assistance system.

12 . The method of claim 1 , further comprising:
in response to determining the current vehicle location is beyond the predetermined distance from the preset location, determining whether the current vehicle location is at a pre-detected ISG suspension location; and in response to determining that the current vehicle location is at the pre-detected ISG suspension location, automatically inhibiting the ISG mode.

13 . A vehicle, comprising:
an engine mounted within the vehicle; and an idle stop and go (ISG) system programmed to automatically inhibit an ISG mode based on detecting whether a current vehicle location is within a predetermined distance from a preset location or a traffic sign.

14 . The vehicle of claim 13 , wherein the ISG mode turns off the engine of the vehicle based on a plurality of conditions.

15 . The vehicle of claim 14 , wherein the conditions include a vehicle speed being detected as 0, an accelerator input being detected as 0, and a brake pedal being engaged.

16 . The vehicle of claim 13 , further comprising:
a vehicle speed sensor configured to detect a current speed of the vehicle; an accelerator pedal having a sensor configured to detect a current engagement amount of the accelerator pedal; a brake pedal having a sensor configured to detect an engagement amount of the brake pedal; and an advanced driver assistance system.

17 . The vehicle of claim 16 , wherein the advanced driver assistance system includes a global positioning system (GPS) configured to detect the current vehicle location and a camera configured to detect the traffic sign.

18 . The vehicle of claim 16 , further comprising:
an ISG button configured to receive manual input to enable or inhibit the ISG mode of the ISG system.

19 . The vehicle of claim 13 , wherein the preset location is a location stored in a navigation system.

20 . The vehicle of claim 13 , wherein the traffic sign is a stop sign, a yield sign, a pedestrian crossing sign, or the like.

21 . A system for controlling an idle stop and go (ISG) of a vehicle, comprising:
a memory configured to store program instructions; and a processor programmed to execute the program instructions, the program instructions when executed configured to:
obtain a current vehicle location;
determine whether the current vehicle location is within a predetermined distance from a preset location or a traffic sign; and
automatically inhibit an ISG mode of the ISG system in response to determining that the current vehicle location is within the predetermined distance from the preset location or the traffic sign.

22 . The system of claim 21 , wherein the determination of whether the current vehicle location is within the predetermined distance from the preset location or the traffic sign is triggered based on engagement of a brake pedal.

23 . The system of claim 21 , wherein the preset location is a location stored in a navigation system.

24 . The system of claim 21 , wherein the current vehicle location is detected using a global positioning system.

25 . The method of claim 21 , wherein the traffic sign is detected using a camera mounted on the vehicle.
