Referring to FIG. 8 , when the vehicle 1 is not in the initial ignition state (NO in 510 ) by the controller 120 , the vehicle 1 may determine the driving state ( 811 ).

The vehicle 1 may measure ambient brightness by the auto light sensor 110 ( 820 ). The auto light sensor 110 may acquire illuminance data for ambient brightness and transmit it to the controller 120 .

The vehicle 1 may determine, by the controller 120 , whether the situation is dark based on the ambient brightness measured by the auto light sensor 110 ( 830 ). The controller 120 may determine whether the situation is dark based on the illuminance data received from the auto light sensor 110 .

The vehicle 1 may receive, by the controller 120 , function selection information of the multi-function switch 50 from the auto light system 50 in a dark situation (Yes in 830 ) ( 840 ). The controller 120 may not receive the function selection information of the multi-function switch 50 from the auto light system 50 if it is not a dark situation (No in 830 ) ( 841 ).

The vehicle 1 turns off both the headlight switch HS and the taillight switch TS based on the function selection information of the multifunction switch 50 received from the auto light system 50 by the controller 120 . It can be determined whether or not (850). When both the headlight switch HS and the taillight switch TS are turned off (YES in S850), the controller 120 may determine whether the auto light switch ARS is OFF (S860). If both the headlight switch HS and the tail light switch TS are not turned off (NO in step 850), the controller 120 may not determine whether the auto light switch ARS is turned off (step 861).

When the auto light switch ARS is turned off by the control unit 120 (Yes in 860), the vehicle 1 repeats based on the number of times of notification and the elapsed time after the notification about the off state of the auto light switch ARS. It is possible to transmit a repeated notification signal for notifying to the notification device 60 (870).

9 is a diagram illustrating a method of transmitting a repeat notification signal for an off state of an auto light switch in the driver assistance system according to an exemplary embodiment.

Referring to FIG. 9 , the vehicle 1 may determine whether the off state of the auto light switch ARS has been notified once by the notification device 60 by the controller 120 ( 871 ). The controller 120 may determine whether the notification has been made once based on the notification signal transmitted to the notification device 60 .

If it is determined by the controller 120 that the vehicle 1 has been notified once (YES in 871), the vehicle 1 may check the number of times of notification for repeated notification (872). The controller 120 may check the number of at least two or more notifications set by manipulation by the driver. For example, the driver may set the number of notifications twice or more. If it is not determined that the controller 120 has been notified once (No in 871), the controller 120 may not check the number of times of notification (873).

The vehicle 1 may determine, by the controller 120 , whether an elapsed time after a notification for repeated notification exceeds a predetermined reference elapsed time based on the confirmed number of notifications ( 874 ). For example, when the number of notifications set by the driver is two, the controller 120 may determine whether the elapsed time after the first notification exceeds a reference elapsed time for performing the second notification.

When the elapsed time after the notification exceeds the reference elapsed time (YES in S874), the vehicle 1 may end the comparison process of the elapsed time and reset the elapsed time by the controller 120 (S875). For example, when the elapsed time after the first notification exceeds a reference elapsed time for performing the second notification, the controller 120 may prepare for transmitting the second notification signal and reset. If the elapsed time after the notification does not exceed the reference elapsed time (No in 874) by the controller 120, the vehicle 1 may continuously determine the comparison process of the elapsed time (876).

When the comparison process of the elapsed time is reset by the control unit 120, the vehicle 1 may count the number of notifications ( 877 ). For example, when the controller 120 prepares to transmit the notification signal twice and resets it, the number of times of the notification may be counted twice by the counter.

When the number of notifications is counted by the control unit 120 , the vehicle 1 may transmit a repeated notification signal to the notification device 60 for an off state of the auto light switch ARS ( 678 ). For example, when the number of times of notification is counted as 2, the controller 120 may transmit a notification signal repeated twice for an off state of the auto light switch ARS to the notification device 60 .

When the control unit 120 transmits a repeat notification signal to the notification device 60 regarding the off state of the auto light switch ARS, the vehicle 1 may determine whether it is the target number of notifications ( 879a ). If it is the target number of notifications based on the confirmed number of notifications (YES in 879a), the controller 120 may not transmit a repeat notification signal for the OFF state of the auto light switch ARS (879b). For example, when the confirmed number of notifications is two and the target number of notifications is two, the controller 120 may not transmit a repeat notification signal for an off state of the auto light switch ARS. If the number of notifications is not the target number of notifications based on the confirmed number of notifications (No in 879a), the control unit 120 provides a repeat notification signal for the OFF state of the auto light switch (ARS) from the comparison process of the elapsed time to match the target number of notifications The transmission process may be sequentially repeated again (872 to 878). For example, when the number of confirmed notifications is 2 and the target number of notifications is 3, the control unit 120 adjusts to the OFF state of the auto light switch (ARS) from the process of comparing the elapsed time so as to match the target number of notifications 3 times. Up to the process of transmitting a repeat notification signal to the user may be sequentially repeated again.

The notification device 60 may receive the repeated notification signal to repeatedly notify the off state of the auto light switch ARS ( 880 ). The notification device 60 may repeatedly notify the off state of the auto light switch ARS every specific time in response to the target notification number.

When the auto light switch ARS is not turned off (NO in 860), the vehicle 1 sends a repeat notification signal for the off state of the auto light switch ARS to the notification device 60 by the controller 120 . It may not be transmitted (890).
