Abstract

Disclosed is a driver assistance apparatus for a vehicle, the apparatus including: a camera configured to acquire a front field-of-view image of the vehicle; an output unit; and a processor configured to detect at least one traffic sign based on the front field-of-view image of the vehicle, determine whether the traffic sign fits travel information of the vehicle, and, when the traffic sign fits the vehicle travel information, perform control to output the traffic sign through the output unit.

First claim

What is claimed is:

1. A driver assistance apparatus for a vehicle, comprising:
a camera configured to acquire a front field-of-view image of the vehicle;
an output unit; and
a processor configured to detect at least one traffic sign based on the front field-of-view image of the vehicle, determine whether the traffic sign fits travel information of the vehicle, and, when the traffic sign fits the travel information, perform control to output the traffic sign through the output unit,
wherein the processor is further configured to:
acquire vehicle speed information, and
when a speed of the vehicle is equal to or lower than a reference speed, perform control not to output the traffic sign even in a case where the traffic sign fits the travel information.

2. The driver assistance apparatus of claim 1 , wherein the processor is further configured to, when the traffic sign does not fit the travel information, perform control not to output the traffic sign.

3. The driver assistance apparatus of claim 1 , further comprising an interface unit,
wherein the processor is further configured to, when the traffic sign fits the travel information, provide at least one of a steering control signal, an acceleration control signal, or a brake control signal through the interface unit based on the traffic sign.

4. The driver assistance apparatus of claim 1 , wherein the traffic sign comprises at least one of a traffic signal marked on a road surface, a traffic signal marked on a traffic signboard, a traffic lamp signal, a construction zone warning signal, a traffic signal attached to another vehicle, or a hand signal.

5. The driver assistance apparatus of claim 4 , further comprising a memory configured to store a priority order of a plurality of traffic signs,
wherein the processor is further configured to, when the plurality of traffic signs fits the travel information, perform control based on the priority order to output a traffic sign having a higher priority level among the plurality of traffic signs.

6. The driver assistance apparatus of claim 5 , wherein the memory is further configured to store the priority order in which the traffic lamp signal has a priority level higher than a priority level of the traffic signal marked on the road surface or the traffic signal marked on the traffic signboard.

7. The driver assistance apparatus of claim 5 , wherein the memory is further configured to store the priority order in which the hand signal has a priority level higher than a priority level of the traffic lamp signal.

8. The driver assistance apparatus of claim 5 , wherein the memory is further configured to store the priority order in which a stop signal marked on the traffic signboard has a highest priority level.

9. The driver assistance apparatus of claim 1 , wherein the travel information comprises at least one of travel road information, travel lane information, destination information, route information, turn signal information, steering information, heading information, or vehicle model information.

10. The driver assistance apparatus of claim 9 , further comprising: a memory configured to store a priority order of a plurality of items of travel information,
wherein the processor is further configured to, when the plurality of items of travel information, determine whether the traffic sign fits an item of travel information having a higher priority level among the plurality of items of travel information, based on the priority order.

11. The driver assistance apparatus of claim 10 ,
wherein the memory is further configured to store the priority order in which the turn signal information has a priority level higher than a priority level of the destination information, and
wherein the processor is further configured to, when the turn signal information and the destination information do not fit each other, determine whether the traffic sign fits the turn signal information.

12. The driver assistance apparatus of claim 1 , wherein the processor is further configured to:
detect a plurality of traffic signs based on the front field-of-view image of the vehicle;
calculate a distance between a vehicle and each of the plurality of traffic signs; and
perform control to output a traffic sign closest to the vehicle among the plurality of traffic signs which fits the travel information.

13. The driver assistance apparatus of claim 1 , wherein the processor is further configured to:
detect a first traffic sign and a second traffic sign based on the front field-of-view image of the vehicle; and
when the first traffic sign fits the travel information and the second traffic sign does not fit the travel information, perform control to output the first traffic sign through the output unit and not to output the second traffic sign.

14. The driver assistance apparatus of claim 1 , further comprising an interface unit,
wherein the processor is further configured to, when state information of the vehicle received based on a driving manipulation signal through the interface unit does not fit output traffic sign information, output an alarm through the output unit.

15. The driver assistance apparatus of claim 1 , wherein the processor is further configured to:
acquire rampway entering situation information related to a rampway; and
perform control to output a traffic sign which fits the travel information among a plurality of traffic signs placed on a plurality of paths forming the rampway.

16. The driver assistance apparatus of claim 1 , wherein the processor is further configured to:
detect a plurality of traffic lamps based on the front field-of-view image of the vehicle; and
perform control to output a traffic sign generated by a traffic lamp closest to the vehicle among a plurality of traffic lamps fitting the travel information.

17. The driver assistance apparatus of claim 1 , wherein the processor is further configured to:
acquire lane information on a lane in which a vehicle is travelling;
detect a plurality of traffic signs based on the front field-of-view image of the vehicle; and
perform control to output a traffic sign which fits the lane information among the plurality of traffic signs.

18. A driver assistance apparatus for a vehicle, comprising:
a camera configured to acquire a front field-of-view image of the vehicle;
an output unit; and
a processor configured to detect at least one traffic sign based on the front field-of-view image of the vehicle, determine whether the traffic sign fits travel information of the vehicle, and, when the traffic sign fits the travel information, perform control to output the traffic sign through the output unit,
wherein the processor is further configured to:
acquire lane information on a lane in which a vehicle is travelling,
detect a plurality of traffic signs based on the front field-of-view image of the vehicle, and
perform control to output a traffic sign which fits the lane information among the plurality of traffic signs,

wherein the plurality of traffic signs comprises a first traffic sign based on a traffic signboard for a permitted left turn of the vehicle, and a second traffic sign based on a traffic lamp for straight running of the vehicle, and
wherein the processor is further configured to:
acquire situation information indicating a situation that the vehicle is travelling on a left-turn lane, and
perform control to output the first traffic sign and not to output the second traffic sign.

19. A driver assistance apparatus for a vehicle, comprising:
a came
