Abstract

A vehicle that is equipped with an idling stop and restarting system and method thereof for testing a function of the idling stop and restarting system may include counting the ignition number of an engine including a first ignition, accumulating the operating time period after the first ignition, and setting a charging value of a battery as a predetermined value, if the ignition number is smaller than a predetermined ignition number and/or if operating time period is shorter than a predetermined operating time period, wherein the idling stop and restarting system is operated regardless of the real charging value of the battery.

Claims

1. A method for testing a function of an idling stop and restarting system of a vehicle that is assembled, comprising:

counting ignition number of an engine including a first ignition,

wherein, if the ignition number is smaller than or equal to a predetermined ignition number, the idling stop and restarting system is operated regardless of real charging value of a battery.

2. The method for testing a function of an idling stop and restarting system of claim 1, wherein a charging value of the battery is set as a predetermined value when the ignition number is smaller than or equal to the predetermined ignition number.

3. The method for testing a function of an idling stop and restarting system of claim 2, wherein the predetermined value is 100%, i.e., a full value.

4. The method for testing a function of an idling stop and restarting system of claim 1, further comprising:

determining, before the counting of the ignition number of the engine, whether a current RPM of the engine is larger than a predetermined RPM value so as to determine whether the engine is ignited or not.

5. The method for testing a function of an idling stop and restarting system of claim 4, wherein the predetermined RPM value is approximately 25.

6. The method for testing a function of an idling stop and restarting system of claim 1, wherein the predetermined ignition number is approximately 10.

7. The method for testing a function of an idling stop and restarting system of claim 1, wherein the idling stop and restarting system is operated based on the real charging value of the battery in case that the ignition number is larger than the predetermined ignition number.

8. The method for testing a function of an idling stop and restarting system, comprising:

accumulating operating time period of the engine after the first ignition,

wherein, if the accumulated operating time period is shorter than or equal to a predetermined operating time period, the idling stop and restarting system is operated regardless of the real charging value of the battery.

9. The method for testing a function of an idling stop and restarting system of claim 8, wherein a charging value of the battery is set as a predetermined value when the accumulated operating time period is shorter than or equal to the predetermined operating time period.

10. The method for testing a function of an idling stop and restarting system of claim 9, wherein the predetermined value is 100%, i.e., a full value.

11. The method for testing a function of an idling stop and restarting system of claim 9, wherein the predetermined operating time period is approximately 1440 sec.

12. The method for testing a function of an idling stop and restarting system of claim 9, wherein the idling stop and restarting system is operated based on the real charging value of the battery in case that the accumulated operating time period is longer than the predetermined operating time period.

13. A vehicle that is equipped with an idling stop and restarting system so as to stop or reignite an engine in the idle condition, comprising:

counting portion for counting ignition number of the engine including a first ignition,

wherein, if the ignition number is smaller than or equal to a predetermined ignition number a control portion operates the idling stop and restarting system regardless of real charging value of a battery.

14. The vehicle that is equipped with an idling stop and restarting system of claim 13, wherein the control portion sets a charging value of the battery as a predetermined value when the ignition number is smaller than or equal to the predetermined ignition number.

15. The vehicle that is equipped with an idling stop and restarting system of claim 14, wherein the predetermined value is 100%, i.e., a full value.

16. The vehicle that is equipped with an idling stop and restarting system of claim 13, wherein the control portion determines, before the counting portion counts the ignition number of the engine, whether a current RPM of the engine is larger than a predetermined RPM value so as to determine whether the engine is ignited or not.

17. The vehicle that is equipped with an idling stop and restarting system, comprising:

accumulating portion for accumulating operating time period of the engine after the first ignition; and

wherein, if the accumulated operating time period is shorter than or equal to a predetermined operating time period, the control portion operates the idling stop and restarting system regardless of the real charging value of the battery.

18. The vehicle that is equipped with an idling stop and restarting system of claim 17, wherein the control portion sets a charging value of the battery as a predetermined value when the accumulated operating time period is shorter than or equal to the predetermined operating time period.

19. The vehicle that is equipped with an idling stop and restarting system of claim 17, wherein the control portion operates the idling stop and restarting system based on the real charging value of the battery in case that the ignition number is larger than the predetermined ignition number and/or the accumulated operating time period is longer than the predetermined operating time period.
