It should be noted that, in the drawing, the complete cut-off line 4 refers to a boundary line at the top of the light emitting area of the second lamp module 3 and a boundary line at the top of the light emitting area where the first lamp module 2 is located. Specifically, as shown in fig. 3, when the second lamp module 3 emits light and the low beam light emitting region 22 of the first lamp module 2 emits light, the cutoff line 4 of the convex portion (i.e., the cutoff line 4 at the top of the low beam light emitting region 22) is centered in the middle region of the first lamp module 2; as shown in fig. 4, when the first light emitting region 21 emits light and the low beam light emitting region 22 is extinguished, the cut-off line 4 corresponding to the convex portion moves to the left region of the first lamp module 2; as shown in fig. 5, or when the second light emitting region 23 emits light and the low beam light emitting region 22 is extinguished, the cut-off line 4 corresponding to the convex portion moves to the right region of the first lamp module 2. I.e. the translation of the cut-off line 4 of the bulge, can realize that the light of the first light module 2 turns with the vehicle.
As shown in fig. 1, an embodiment of the present application provides a front combination lamp control method, which includes the following steps:

step S200: the controller controls to light up the first light emitting region 21 on the left side of the low beam light emitting region 22 based on the vehicle left turn signal or controls to light up the second light emitting region 23 on the right side of the low beam light emitting region 22 based on the vehicle right turn signal.
Specifically, the near-vehicle illumination area can be realized through the low-beam light-emitting area 22 of the first lamp module 2, the cut-off line 4 is positioned at the top of the low-beam light-emitting area 22 (as shown in fig. 3), when the subsequent controller receives a left turn signal of the vehicle, the controller can control the first light-emitting area 21 to be lightened, so that the cut-off line 4 at the top of the low-beam light-emitting area 22 extends leftwards to be longer, and the left movement adjusting effect similar to the cut-off line 4 is achieved; or when the controller receives a vehicle right turning signal, the controller controls the second light-emitting area 23 to be lightened, so that the cut-off line 4 extends rightwards, and the effect of rightwards moving and adjusting the cut-off line 4 is achieved; therefore, the effect of the rotation of the light of the first lamp module 2 along with the direction is realized, the irradiation mode of the front combination lamp is automatically changed, and the safety of night driving is greatly improved during steering.

the controller controls the number of lamps on the right side portion in the low beam light emitting region 22 to be turned off one by one in a direction consistent with the steering direction of the vehicle. When the partial lamps far from the first light-emitting area 21 in the low beam light-emitting area 22 are extinguished, the partial lamps can also be extinguished one by one, so that the partial extinction of the low beam light-emitting area 22 is more natural, the overall brightness of the first lamp module 2 is ensured to be consistent, and the phenomenon of sudden and sudden brightness is avoided.
Of course, in the same way, when the vehicle turns right, the controller can control the lamp in the second light-emitting area 23 to be turned on, and can also extinguish part of the lamps in the low beam light-emitting area 22 far away from the second light-emitting area 23, so that the cut-off line 4 of the first lamp module 2 can move more naturally. The overall length of the cut-off line 4 is ensured to be unchanged.
Further, the controller may control the number of lamps at the left side portion in the low beam light emitting region 22 to be turned off one by one in a direction consistent with the steering direction of the vehicle. When the partial lamps far from the second light-emitting area 23 in the low beam light-emitting area 22 are extinguished, the partial lamps can also be extinguished one by one, so that the partial extinction of the low beam light-emitting area 22 is more natural, the overall brightness of the first lamp module 2 is ensured to be consistent, and the phenomenon of sudden and sudden brightness is avoided.

The safety of the driver in the right turn direction can be ensured.
In some embodiments, the controller controls the number of lights in the first light emitting area 21 to be lit based on the left steering angle of the vehicle; wherein, the magnitude of the steering angle of the vehicle is proportional to the number of the lighting lamps. Wherein, the number of the lights in the first light-emitting area 21 can be controlled according to the angle of the left steering of the vehicle, namely, the larger the angle of the left steering of the vehicle is, the more the number of the lights in the first light-emitting area 21 is; the realization can more laminate real driving scene.
Of course, the same way, the number of the lights in the second light-emitting area 23 can be controlled according to the right steering angle of the vehicle, that is, the larger the right steering angle of the vehicle is, the more the lights in the second light-emitting area 23 are; the realization can more laminate real driving scene.
Further, the lamps in the first and second light emitting regions 21 and 23 may be lighted in a one-by-one lighting mode, and the one-by-one lighting direction coincides with the turning direction of the vehicle.
In some embodiments, the controller controls the first light-emitting region 21 to be lit and the lamps to be extinguished by the number of right portions in the low-beam light-emitting region 22 based on the vehicle left turn signal. When the vehicle turns left, the control unit can turn off the part of the lamps far from the first light-emitting area 21 in the low beam light-emitting area 22 while turning on the lamps in the first light-emitting area 21, so that the cut-off line 4 of the first lamp module 2 can move more naturally.
