[0035] With the improvement of living standards and the acceleration of pace, cars have become an indispensable means of transportation in life, and automobile lamps are an important part of cars. At present, the existing headlight lamp caps are all separated, large in size, and have a relatively large restriction on the design.

The headlight, based on a control signal, couples a lamp head via an output port of a control motor to an interface corresponding to a target lighting function among multiple interfaces of the lamp head, thereby enabling the lamp head to achieve the target lighting function. This eliminates the need for multiple lamp heads to achieve functions such as high beam, width indicator, or low beam, reducing the size of the headlight and avoiding restrictions on the vehicle's styling due to the bulk of the headlight.

[0039] In some embodiments, the lamp head 101 may further include a plurality of low beam interfaces with different light heights according to actual needs, and this embodiment of the present application does not impose any specific limitation on this.
[0040] For example, when the angle perpendicular to the ground is 0 degrees, the lamp head 101 may include a low beam interface with a light height of 70 degrees, a low beam interface with a light height of 75 degrees, and a low beam interface with a light height of 80 degrees.

[0042] In some embodiments, an extension at the output port of the motor 102 is selectively coupled to one of a plurality of interfaces of the lamp head.
[0043] In some embodiments, the output port of the motor 102 is selectively coupled to one of the multiple interfaces of the lamp head to place the lamp head in a gear corresponding to the target lighting function. The working principle of the motor 102 is to use an energized coil to generate a rotating magnetic field, which acts on the rotor to generate a magneto-electrodynamic rotational torque.
[0044] In some embodiments, the relay 103 is used to control the rotation of the output port of the motor. The relay 103 can be an electromagnetic relay, a thermal reed relay, or a solid-state relay, which is not limited in this application.
[0045] In some embodiments, the micro control unit 104 is coupled to the relay and the lamp holder respectively.
[0046] In some embodiments, the micro control unit 104 includes a FLASH storage module that is used to store at least one pulse width modulation (PWM) signal, and the micro control unit 104 can adjust the brightness level of the lamp head according to the PWM signal.
[0047] Exemplarily, the FLASH storage module stores a first PWM signal, a second PWM signal, and a third PWM signal; the first PWM signal, the second PWM signal, and the third PWM signal have different duty cycles. The first PWM signal is used to indicate that the headlight brightness level is in the high beam position, the second PWM signal is used to indicate that the headlight brightness level is in the low beam position, and the third PWM signal is used to indicate that the headlight brightness level is in the width marker position.
[0048] In some embodiments, the CAN chip 105 is coupled to the MCU 104 . The CAN chip 105 is configured to obtain a first control signal corresponding to a target light function and output the control signal to the MCU 104 .
[0049] In some embodiments, the vehicle lamp may further include a ripple detection module 106 .
[0050] In some embodiments, the microcontroller unit 104 is configured to: receive a first control signal; and output a second control signal to the relay based on the first control signal, so that the output port of the MCU-controlled motor is coupled to the interface corresponding to the target lighting function among the multiple interfaces of the lamp head.
[0051] As can be seen from the above, the present application provides a lamp head with multiple interfaces. By controlling the output port of the motor to couple with the interface corresponding to the target lighting function among the multiple interfaces of the lamp head, the lamp head can realize the target lighting function, which can be high beam, width indicator light, or low beam. This eliminates the need for multiple lamp heads to realize high beam, width indicator light, or low beam functions, thus reducing the size of the headlight and avoiding the restrictions on the vehicle's styling caused by the large headlight.
[0052] In some embodiments, the input of the ripple detection module 106 is coupled to the motor 102, and the output of the ripple detection module 106 is coupled to the microcontroller unit 104. The ripple detection module 106 is configured to detect the ripple signal of the motor, amplify the ripple signal, convert it into a square wave signal, and output the square wave signal to the microcontroller unit 104.
[0053] In some embodiments, the micro control unit 104 is further configured to: receive a square wave signal; and determine, based on the square wave signal, whether the output port of the motor is coupled to an interface corresponding to the target lighting function among the multiple interfaces of the lamp holder.
[0054] As can be seen from the above, the ripple detection module in this application converts the motor's ripple signal into a square wave signal, allowing the MCU module to determine the location of the motor's output port based on the square wave signal. The MCU uses the square wave signal output by the ripple detection module to determine whether the motor's output port is coupled to the interface corresponding to the target lighting function on the lamp head, thereby avoiding incorrect connection between the motor's output port and the lamp head's interface.
[0055] In some embodiments, the micro control unit 104 is further configured to: after the output port of the motor is coupled to the interface corresponding to the target lighting function among the multiple interfaces of the lamp head, adjust the brightness level of the lamp head to the brightness level corresponding to the target lighting function according to the first control signal.
[0056] According to the above content, the present application adjusts the brightness of the lamp head according to the first control signal, so that the output port of the motor of the lamp head is coupled with the interface corresponding to the target light function on the lamp head, and is adjusted to a matching brightness level.
[0057] In some embodiments, the micro control unit 104 is specifically configured to: output a third control signal to the lamp holder according to the first control signal; the third control signal is a pulse width modulation (PWM) signal.
[0058] According to the above content, the present application uses a PWM signal matching the first control signal to control the lamp head to adjust to a matching brightness level according to the first control signal, which can make the brightness of the lamp head more stable.
[0059] See also Figure 3 As shown, an embodiment of the present application further provides a vehicle lamp system, which includes: a vehicle lamp 10, a light handle 20, a vehicle terminal 30 and a vehicle body control module electronic control unit 40.
[0060] In some embodiments, the light handle 20 is used to send a control signal to control the vehicle light 10 to turn on the high beam, low beam or width indicator light.
[0061] In some embodiments, the vehicle terminal 30 is used to send a control signal to control the vehicle light 10 to turn on the high beam, low beam or width indicator light.
[0062] In some embodiments, the body control module electronic control unit 40 is electrically connected to the vehicle light 10, the light handle 20, and the vehicle terminal 30. The body control module is configured to receive a first control signal corresponding to a target light function from the light handle and / or the vehicle terminal; and transmit the first control signal to the vehicle light to activate the target light function.
[0063] In some embodiments, the BCM ECU 40 sends the first control signal to the CAN chip 105 of the vehicle lamp 10 .
[0064] Based on the above lights, such as Figure 4 As shown, an embodiment of the present application provides a method for controlling a vehicle lamp, which is applied to the microcontroller unit of the vehicle lamp. The method includes the following steps:
[0065] S101: Acquire a first control signal.
[0066] Among them, the first control signal represents a control signal corresponding to the target lighting function, which can be one of a high beam signal, a low beam signal and a width indicator light signal.
[0067] In some embodiments, the conversion control local area network (CAN) chip obtains a first control signal sent by an electronic control unit of a vehicle body control module, and sends the first control signal to a micro control unit.
[0068] S102: Output a second control signal to the relay according to the first control signal, so that the microcontroller unit MCU controls the output port of the motor to couple with an interface corresponding to the target lighting function among the multiple interfaces of the lamp holder.
[0069] The second control signal is used to close the relay to drive the motor to start rotating.
[0070] S103: Receive the square wave signal sent by the ripple detection module.
[0071] The square wave signal is obtained by amplifying and converting the detected ripple signal by the ripple detection module.
[0072] S104: Determine, based on the square wave signal, whether the output port of the motor is coupled to an interface corresponding to the target lighting function among the multiple interfaces of the lamp holder.
[0073] The wave signal is obtained by amplifying and converting the detected ripple signal by the ripple detection module.
[0074] In some embodiments, the microcontroller unit presets a correspondence between the number of square waves and the rotational position of the motor. The number of square waves in the square wave signal varies depending on the rotational position of the motor. Based on the number of square waves in the square wave signal and the preset correspondence between the number of square waves and the rotational position of the motor, the microcontroller determines whether the output port of the motor is coupled to an interface corresponding to a target lighting function among the multiple interfaces of the lamp holder.
[0075] S105 , after the output port of the motor is coupled to the interface corresponding to the target lighting function among the multiple interfaces of the lamp holder, adjust the brightness level of the lamp holder to the brightness level corresponding to the target lighting function according to the first control signal.
[0076] In some embodiments, a third control signal is output to the lamp head according to the first control signal to adjust the brightness level of the lamp head to a brightness level corresponding to the target lighting function.
[0077] The third control signal is a pulse width modulation (PWM) signal, which is used to adjust the brightness level of the lamp head to a brightness level corresponding to the target lighting function.
[0078] According to the above content, the present application uses a PWM signal matching the first control signal to control the lamp head to adjust to a matching brightness level according to the first control signal, which can make the brightness of the lamp head more stable.
[0079] Exemplarily, when the first control signal is a high-beam signal, the target lighting function is a high-beam function. The microcontroller unit receives and converts the first control signal sent by the control area network (CAN) chip and, based on the first control signal, sends a second control signal to the relay, thereby engaging the relay and driving the motor. The microcontroller unit determines whether the motor output port is coupled to the high-beam interface of the lamp holder based on the square wave signal sent by the ripple detection module. If the motor output port is coupled to the high-beam interface of the lamp holder, the microcontroller unit outputs a PWM signal to the lamp holder for adjusting the lamp holder's brightness level to the high-beam level.
[0080] In another exemplary embodiment, when the first control signal is a low-beam signal, the target light function is a low-beam function. The microcontroller unit receives and converts the first control signal sent by the control area network (CAN) chip and, based on the first control signal, sends a second control signal to the relay to energize the relay and drive the motor. The microcontroller unit determines whether the motor output port is coupled to the low-beam interface of the lamp holder based on the square wave signal sent by the ripple detection module. If the motor output port is coupled to the low-beam interface of the lamp holder, the microcontroller unit outputs a PWM signal to the lamp holder for adjusting the lamp's brightness level to the low-beam level.
[0081] In another exemplary embodiment, when the first control signal is a width light signal, the target light function is a width light function. The microcontroller unit receives and converts the first control signal sent by the CAN chip, and sends a second control signal to the relay based on the first control signal, so that the relay is attracted and the motor is driven to rotate. The microcontroller unit determines whether the output port of the motor is coupled to the width light interface of the lamp head based on the square wave signal sent by the ripple detection module; if the output port of the motor is coupled to the width light interface of the lamp head, the microcontroller outputs a PWM signal to the lamp head for adjusting the brightness level of the lamp head to the width light level.
[0082] As can be seen from the foregoing, in the method provided in the embodiments of the present application, the first control signal is used to control the lamp head to achieve the target lighting function, which can be high beam, width marker light, or low beam. This eliminates the need for multiple lamp heads to achieve these functions, reducing the size of the headlights and avoiding restrictions on the vehicle's styling due to the bulk of the headlights.
