Vehicle headlamp system and method of controlling the same
A vehicle headlamp system providing a glare-free high beam. A forward image-capturing device captures a forward image ahead of a vehicle on which the headlamp system is disposed. A blind spot sensor detects blind spots to side and rear of the vehicle. A headlamp lights ahead of the vehicle based on a set illumination area. An electronic control unit (ECU) generates a control command for controlling an illumination area of the headlamp, based on the forward image captured using the forward image-capturing device and information regarding the blind spots detected by the blind spot sensor. A driving unit drives the headlamp based on the control command from the ECU.
1. A vehicle headlamp system, comprising:
a forward image-capturing device configured to capture a forward image ahead of a vehicle in which the headlamp system is provided;
a radar sensor configured to detect an object ahead of the vehicle;
a blind spot sensor configured to detect blind spots to side and rear of the vehicle;
a headlamp configured to light ahead of the vehicle based on a set illumination area;
an electronic control unit configured to generate a control command for controlling an illumination area of the headlamp, based on the forward image captured by the forward image-capturing device and information regarding the blind spots detected by the blind spot sensor; and
a driving unit configured to operate the headlamp based on the control command received from the electronic control unit,
wherein the headlamp comprises an adaptive driving beam headlamp configured to emit a high beam or a low beam, depending on the set illumination area,
wherein, when neither a preceding vehicle nor a passing vehicle is determined to be present according to a result of analyzing the forward image and the information regarding the blind spots, the electronic control unit is configured to cause the high beam to be emitted,
wherein, in a case in which a preceding vehicle is present, the electronic control unit is configured to cause the high beam to be emitted when the preceding vehicle is determined to be present based on radar information obtained by the radar sensor but not to be present in the forward image, and further configured to cause the low beam to be emitted when the preceding vehicle is determined to be present based on the radar information and the forward image.
2. The vehicle headlamp system according to claim 1 , wherein the electronic control unit is configured to cause the high beam to be turned off and the low beam to be turned on, when a right or left passing vehicle is present according to a result of analyzing the forward image and the information regarding the detected blind spots.
3. The vehicle headlamp system according to claim 2 , wherein the electronic control unit is configured to cause a portion of the headlamp to be turned off so that a right or left portion of the illumination area, corresponding to the passing vehicle, is reduced.
