[0027] In order to make the objectives, technical solutions and advantages of the present application clearer, the implementation methods of the present application will be further described in detail below with reference to the accompanying drawings.

[0028] The present application provides a method for controlling a high beam lamp. Figure 1 , which shows a schematic diagram of the implementation environment of the method provided in the embodiment of the present application. The implementation environment may include: IDM (Intelligent Driver-Monitoring, intelligent driving module) 11, IEBM (Integrated Electronic Brake Module, electronic brake integrated module) 12, EPS (Electric Power Steering, electric power steering system) 13, VCCM (Vehicle Central Control Module, central control module) 14, ETRS (Electronic Transmission Range Selector, electronic shifter) 15, FVC (Front View Camera, front view camera) 16, ECU (Electronic Control Unit, electronic control unit) 17, ICM (Intelligent Cockpit Module, intelligent cockpit module) 18, ZCU_L (Left Zone Control Unit, left zone controller) 19, left front high beam 20 and right front high beam 21.

[0029] Optionally, IDM11 obtains the power-on status of the vehicle power supply through ZCU_L19, and obtains the on / off status of the automatic mode of the vehicle combination switch through the vehicle combination switch module. When it is determined that the vehicle power supply is in the ON state and the automatic mode of the vehicle combination switch is turned on, IDM11 reads the on / off status of the soft switch corresponding to the intelligent high beam from ICM18.

[0030] Exemplarily, after receiving the start signal of the intelligent high beam function, IDM11 can obtain the gear information of the vehicle through VCCM14; obtain the power-on status of the vehicle's ignition key through ECU17; read the opening and closing status of the vehicle's rear fog lights from the vehicle's ZCU_L19; read the vehicle's driving speed through IEBM12; collect images within a first preset range around the vehicle through FVC16, and then use an image recognition device to identify the grayscale value of each pixel in the image, and calculate the illumination of the vehicle's environment based on the grayscale value; identify whether there are faults and occlusions in the image returned by FVC16 through the image recognition device; and identify pedestrians and other vehicles in the image through the image recognition device.

[0031] In one possible implementation, if the vehicle power is in the ON state or the RUN state, the gear is in D (Drive), the ignition key is powered on, the vehicle's rear fog lights are off, the driving speed is within a second preset range, the illuminance is less than the illuminance threshold, the front-view camera has no faults or obstructions, and there are no pedestrians or other vehicles within a certain distance in front of the vehicle, IDM11 determines that the vehicle meets the conditions for activating the intelligent high beam function.

[0032] Optionally, after determining that the vehicle meets the conditions for activating the intelligent high beam function, IDM11 identifies through the image recognition device whether there are lit front high beams of an oncoming vehicle, lit rear fog lights of the vehicle in front, or other luminous objects in the image returned by FVC16. If there are no lit front high beams of an oncoming vehicle, lit rear fog lights of the vehicle in front, or other luminous objects in the video image, IDM11 determines that the detection result of the ambient light source in the vehicle indicates that there are no other light sources within the first preset range around the vehicle.

[0033] In one possible implementation, in response to the detection result of the ambient light source of the vehicle indicating that there are no other light sources within the first preset range around the vehicle, IDM11 reads the setting state of the sensitivity switch through ICM18, and then determines the lighting speed and the extinguishing speed based on the sensitivity. IDM11 drives the left front high beam 20 through ZCU_L19 to gradually increase the light intensity and the irradiation distance at the current lighting speed until the left front high beam 20 is fully turned on; sends a request to VCCM14 to control the lighting of the right front high beam 21 through ZCU_L19, and drives the right front high beam 21 through VCCM14 to gradually increase the light intensity and the irradiation distance at the current lighting speed until the right front high beam 21 is fully turned on. At the same time, IDM11 controls the low beam through the vehicle's combination switch module to gradually reduce the light intensity and the irradiation distance at the current extinguishing speed until the low beam is completely extinguished. After the high beam is fully turned on and the low beam is fully turned off, the IDM 11 lights up the high beam icon in the display screen of the ICM 18 and the indicator light for controlling the IHBC (Intelligence High beam control) lights up in white.

[0034] Exemplarily, after the high beam of the vehicle is turned on based on sensitivity control, if there is at least one of the lighted headlights of the oncoming vehicle, the lighted taillights of the vehicle in front, or other luminous objects in the video image, IDM11 controls the high beam to be turned off based on sensitivity. After the high beam is completely turned off and the low beam is completely turned on, IDM11 controls the high beam icon in the display screen of ICM18 to turn off, and controls the indicator light of IHBC to remain in a white light state. If IDM11 detects that at least one of the high beam cannot be controlled or the high beam is incorrectly controlled, it controls the indicator light of IHBC to light up in red and flash for a certain period of time, displays text information of intelligent high beam function failure on the display screen of ICM18, and controls the soft switch corresponding to the intelligent high beam to be turned off and grayed out through ICM18.

[0035] Optionally, IDM11 obtains the status of the vehicle's wipers through ZCU_L19, the speed of the steering wheel through EPS13, and the on / off status of the high beam switch through ETRS15. If the wiper is in high gear, the vehicle's driving speed is within the second preset range, and the front-view camera is faulty or blocked, IDM11 controls the intelligent high beam function to be interrupted after a preset time. If the steering wheel speed is greater than the speed threshold, the high beam switch is turned on, and the rear fog lights of the vehicle are on, IDM11 controls the intelligent high beam function to be interrupted immediately. If a fault in the intelligent high beam function is detected, the vehicle power is switched to the OFF state, the vehicle exits the startup state, and the vehicle's gear is in D gear, IDM11 controls the vehicle to exit the intelligent high beam function.

[0036] Among them, IDM11, IEBM12, EPS13, VCCM14, ETRS15, FVC16, ECU17, ICM18, ZCU_L19, left front high beam 20 and right front high beam 21 establish communication connection through a wired or wireless network.

[0037] Based on the above Figure 1 In the implementation environment shown in FIG. 1 , the present application embodiment provides a method for controlling a high beam lamp. Figure 2 As shown, taking the method applied to IDM as an example, the method includes steps 201 to 205.

[0038] In step 201 , when the vehicle power is in the ON state and the automatic mode of the vehicle combination switch is turned on, the IDM receives a start signal of the intelligent high beam function.

[0039] In a possible implementation, the IDM can obtain the power-on status of the vehicle power supply through ZCU_L, where the power-on status of the vehicle includes ON and OFF (power off). The IDM can also obtain the opening and closing status of the automatic mode of the vehicle combination switch through the vehicle combination switch module, where the combination switch is used for automatic control of vehicle lights.

[0040] Exemplarily, when it is determined that the vehicle power is in the ON state and the automatic mode of the vehicle combination switch is turned on, the IDM receives the start signal of the intelligent high beam function, including: the IDM reads the opening and closing status of the soft switch corresponding to the intelligent high beam from the ICM. Optionally, the user can click on the driving assistance function on the screen of the ICM to enter the interface corresponding to the driving assistance function, and then select the soft switch to turn on the intelligent high beam function, thereby turning on the intelligent high beam function. After the user turns on the intelligent high beam function, the ICM sends a start signal of the intelligent high beam function to the IDM.

[0041] In step 202, in response to receiving a start signal of the smart high beam function, the IDM obtains a detection result of a condition for activating the smart high beam function, and the detection result of the condition for activating the smart high beam function is used to indicate whether the vehicle meets the condition for activating the smart high beam function.

[0042] Exemplarily, after receiving a start signal of the smart high beam function, the IDM obtains a detection result of a condition for activating the smart high beam function, wherein the detection result of the condition for activating the smart high beam function is used to indicate whether the vehicle meets the condition for activating the smart high beam function.

[0043] Optionally, obtaining the detection results of the conditions for activating the intelligent high beam function includes: obtaining a first detection result, a second detection result, a third detection result, a fourth detection result, a fifth detection result, a sixth detection result and a seventh detection result, wherein the first detection result is used to indicate whether the gear position of the vehicle is in the D gear, the second detection result is used to indicate whether the power-on state of the ignition key of the vehicle is powered on, the third detection result is used to indicate whether the rear fog lamp of the vehicle is in the off state, the fourth detection result is used to indicate whether the driving speed of the vehicle is within a second preset range, the fifth detection result is used to indicate whether the illumination of the environment where the vehicle is located is less than the illumination threshold, and the sixth detection result is used to indicate whether there is a fault and obstruction in the front view camera, The seventh detection result is used to indicate whether there are pedestrians or other vehicles within a certain distance in front of the vehicle; in response to the power of the whole vehicle being in the ON state or the RUN state, the first detection result indicates that the gear is in the D gear, the second detection result indicates that the power-on state of the ignition key is powered on, the third detection result indicates that the rear fog lights of the vehicle are off, the fourth detection result indicates that the driving speed is within the second preset range, the fifth detection result indicates that the illuminance is less than the illuminance threshold, the sixth detection result indicates that there is no fault or obstruction in the front-view camera, the seventh detection result indicates that there are no pedestrians or other vehicles within a certain distance in front of the vehicle, and the detection result of the conditions for activating the intelligent high beam function indicates that the vehicle meets the conditions for activating the intelligent high beam function.

[0044] Next, examples are given for the methods of obtaining each test result.

[0046] Optionally, the first detection result is used to indicate whether the gear position of the vehicle is in the D gear, and the IDM obtains the first detection result, including: the IDM can obtain the gear position information of the vehicle through the VCCM, wherein the gear position information of the vehicle includes P (Parking) gear, R (Reverse) gear, N (Neutral) gear, S (Sport) gear, D gear, and L (Low) gear. Exemplarily, if the gear position information obtained by the IDM is the D gear, the first detection result indicates that the gear position of the vehicle is in the D gear.

[0047] (2) Obtaining the second detection result

[0048] Exemplarily, the second detection result is used to indicate whether the power-on state of the vehicle's ignition key is powered on, and the IDM obtains the second detection result, including: the IDM can obtain the power-on state of the vehicle's ignition key through the ECU, wherein the power-on state of the ignition key includes ON and OFF.

[0050] In one possible implementation, the third detection result is used to indicate whether the rear fog lights of the vehicle are in the off state. The IDM obtains the third detection result, including: the IDM can read the on and off status of the rear fog lights of the vehicle from the ZCU_L of the vehicle. If the read on and off status of the rear fog lights is in the off state, the third detection result indicates that the rear fog lights of the vehicle are in the off state.

[0052] Exemplarily, the fourth detection result is used to indicate whether the driving speed of the vehicle is within the second preset range, and the IDM obtains the fourth detection result, including: the IDM can read the driving speed of the vehicle through the IEBM, and compare the driving speed of the vehicle with the speed threshold corresponding to the second preset range. If the driving speed of the vehicle is within the speed threshold corresponding to the second preset range, the fourth detection result indicates that the driving speed of the vehicle is within the second preset range. Optionally, the speed threshold corresponding to the second preset range can be set based on experience, for example, it can be set to 40 kilometers per hour-135 kilometers per hour.

[0053] (5) Obtain the fifth test result

[0054] Exemplarily, the fifth detection result is used to indicate whether the illumination of the environment where the vehicle is located is less than the illumination threshold, and the IDM obtains the fifth detection result, including: the IDM can detect the illumination of the environment where the vehicle is located through the FVC, and compare the detected illumination of the environment where the vehicle is located with the illumination threshold, if the illumination of the environment where the identified vehicle is located is less than the illumination threshold, the fifth detection result indicates that the illumination is less than the illumination threshold. Optionally, the illumination threshold can be set based on experience, for example, it can be set to 5lux (lux).

[0055] In a possible implementation, the IDM detects the illumination of the environment where the vehicle is located through the FVC, including: collecting images within a first preset range around the vehicle through the FVC, then identifying the gray value of each pixel in the image through an image recognition device, calculating the average gray value of each pixel in the image, and then calculating the illumination value corresponding to the average gray value as the illumination of the environment where the vehicle is located. Exemplarily, the first preset range can be set based on experience.

[0056] (6) Obtaining the sixth test result

[0057] Optionally, the sixth detection result is used to indicate whether there is a fault or occlusion in the front-view camera. The IDM obtains the sixth detection result, including: the IDM can identify whether there is a fault or occlusion in the image returned by the FVC through an image recognition device. If it is identified that the returned image does not have abnormal occlusion or image quality problems, the sixth detection result indicates that there is no fault or occlusion in the front-view camera.

[0058] (7) Obtain the seventh test result

[0059] Exemplarily, the seventh detection result is used to indicate whether there are pedestrians or other vehicles within a certain distance in front of the vehicle. IDM obtains the seventh detection result, including: IDM identifies pedestrians and other vehicles in the image through an image recognition device. If there are no pedestrians or other vehicles within a certain distance in front of the vehicle, the seventh detection result indicates that there are no pedestrians or other vehicles within a certain distance in front of the vehicle.

[0060] In one possible implementation, if the power of the entire vehicle is in the ON state or the RUN state, the first detection result indicates that the gear is in D, the second detection result indicates that the power-on state of the ignition key is powered on, the third detection result indicates that the rear fog lights of the vehicle are off, the fourth detection result indicates that the driving speed is within a second preset range, the fifth detection result indicates that the illuminance is less than the illuminance threshold, the sixth detection result indicates that there is no fault or obstruction in the front-view camera, the seventh detection result indicates that there are no pedestrians or other vehicles within a certain distance in front of the vehicle, and the detection result of the IDM determining the conditions for activating the intelligent high beam function indicates that the vehicle meets the conditions for activating the intelligent high beam function.

[0061] In step 203, in response to the detection result of the conditions for activating the intelligent high beam function indicating that the vehicle meets the conditions for activating the intelligent high beam function, the IDM obtains the detection result of the ambient light source of the vehicle, and the detection result of the ambient light source of the vehicle is used to indicate whether there are other light sources within a first preset range around the vehicle.

[0062] In one possible implementation, after determining that the detection result of the conditions for activating the intelligent high beam function indicates that the vehicle meets the conditions for activating the intelligent high beam function, the IDM obtains the detection result of the ambient light source in the vehicle, wherein the detection result of the ambient light source in the vehicle is used to indicate whether there are other light sources within a first preset range around the vehicle.

[0063] Exemplarily, the IDM obtains the detection result of the ambient light source of the vehicle, including: obtaining and identifying a video image within a first preset range around the vehicle; in response to the absence of lit front high beams of an oncoming vehicle, lit rear fog lights of a vehicle in front, or other luminous objects in the video image, the detection result of the ambient light source of the vehicle indicates that there are no other light sources within the first preset range around the vehicle.

[0064] Optionally, the IDM can identify through an image recognition device whether there are lit front high beams of an oncoming vehicle, lit rear fog lights of a vehicle in front, or other luminous objects in the image returned by the FVC. If there are no lit front high beams of an oncoming vehicle, lit rear fog lights of a vehicle in front, or other luminous objects in the video image, the detection result of the ambient light source of the vehicle indicates that there are no other light sources within a first preset range around the vehicle; if there are at least one of lit front high beams of an oncoming vehicle, lit rear fog lights of a vehicle in front, or other luminous objects in the video image, the detection result of the ambient light source of the vehicle indicates that there are other light sources within the first preset range around the vehicle.

[0065] In one possible implementation, before the IDM uses an image recognition device to identify whether there are lit front high beams of an oncoming vehicle, lit rear fog lights of the vehicle in front, or other luminous objects in the image returned by the FVC, it constructs a recognition model of the front high beams of the oncoming vehicle, the rear fog lights of the vehicle in front, and other common light sources through a convolutional neural network in advance, and then recognizes the image returned by the FVC through the recognition model to confirm whether there are lit front high beams of an oncoming vehicle, lit rear fog lights of the vehicle in front, or other luminous objects in the image returned by the FVC.

[0066] In step 204 , in response to the detection result of the ambient light source of the vehicle indicating that there are no other light sources within a first preset range around the vehicle, the IDM reads the sensitivity of the intelligent high beam function.

[0067] Exemplarily, after determining that the detection result of the ambient light source of the vehicle indicates that there are no other light sources within a first preset range around the vehicle, the IDM reads the sensitivity of the intelligent high beam function, including: the IDM reads the setting state of the sensitivity switch through the ICM, wherein the sensitivity switch is located below the soft switch of the intelligent high beam function, and includes three states of low sensitivity, medium sensitivity and high sensitivity that can be set. Optionally, when the soft switch of the intelligent high beam function is turned off, the sensitivity switch is turned off and cannot be turned on.

[0068] In a possible implementation, the schematic diagram of the soft switch corresponding to the intelligent high beam lamp being turned on and the sensitivity switch being in a high sensitivity state is as follows: Figure 3 As shown; the schematic diagram of the soft switch corresponding to the intelligent high beam is turned on and the sensitivity switch is in the medium sensitivity state is as follows Figure 4 As shown; the soft switch corresponding to the intelligent high beam is closed and the schematic diagram is as follows Figure 5 shown.

[0069] In step 205 , the IDM controls the vehicle's high beam to be turned on based on the sensitivity.

[0070] Optionally, after determining the current position of the sensitivity switch, the IDM controls the vehicle's high beam to turn on based on the sensitivity, including: determining the lighting speed and the extinguishing speed based on the sensitivity; controlling the high beam to gradually increase the light intensity and the illumination distance at the lighting speed until the high beam is fully turned on; controlling the low beam to gradually reduce the light intensity and the illumination distance at the extinguishing speed until the low beam is completely extinguished.

[0071] In one possible implementation, after determining the setting state of the sensitivity, the lighting speed and the extinction speed are determined based on the sensitivity, including: in response to the setting state of the sensitivity being low sensitivity, determining the lighting speed to be a first lighting speed, and determining the extinction speed to be a first extinction speed; in response to the setting state of the sensitivity being medium sensitivity, determining the lighting speed to be a second lighting speed, and determining the extinction speed to be a second extinction speed, wherein the second lighting speed is greater than the first lighting speed, and the second extinction speed is greater than the first extinction speed; in response to the setting state of the sensitivity being high sensitivity, determining the lighting speed to be a third lighting speed, and determining the extinction speed to be a third extinction speed, wherein the third lighting speed is greater than the second lighting speed, and the third extinction speed is greater than the second extinction speed.

[0072] Optionally, the first lighting speed, the second lighting speed, the third lighting speed, the first turning off speed, the second turning off speed and the third turning off speed may be set based on experience.

[0073] In a possible implementation, after determining the current lighting speed of the high beam and the current extinguishing speed of the low beam, the IDM drives the left front high beam 20 through ZCU_L to gradually increase the light intensity and irradiation distance at the current lighting speed until the left front high beam 20 is fully turned on; sends a request to control the lighting of the right front high beam to VCCM through ZCU_L, and drives the right front high beam through VCCM to gradually increase the light intensity and irradiation distance at the current lighting speed until the right front high beam is fully turned on. At the same time, the IDM controls the low beam through the vehicle's combination switch module to gradually reduce the light intensity and irradiation distance at the current extinguishing speed until the low beam is completely turned off.

[0074] Exemplarily, after the high beam is fully turned on and the low beam is fully turned off, the IDM lights up the high beam icon in the display screen of the ICM and controls the indicator light of the IHBC to light up in white.

[0075] Optionally, after the vehicle's high beam is turned on based on sensitivity control, in response to the presence of at least one of lit headlights of an oncoming vehicle, lit taillights of a vehicle in front, or other luminous objects in the video image, the high beam is turned off based on sensitivity control.

[0076] In a possible implementation, after the high beam of the vehicle is turned on based on sensitivity control, the image within the first preset range around the vehicle is continuously collected through FVC, and then the image recognition device is continuously used to identify whether there are lit front high beams of the oncoming vehicle, lit rear fog lights of the vehicle in front, or other luminous objects in the image returned by FVC. If at least one of the lit headlights of the oncoming vehicle, lit taillights of the vehicle in front, or other luminous objects exists in the video image, the IDM controls the high beam to be turned off based on sensitivity, including: the IDM controls the left front high beam 20 through ZCU_L to gradually reduce the light intensity and irradiation distance at the current extinguishing speed until the left front high beam 20 is completely extinguished; sends a request to VCCM to control the right front high beam to be extinguished through ZCU_L, and controls the right front high beam through VCCM to gradually reduce the light intensity and irradiation distance at the current extinguishing speed until the right front high beam is completely extinguished. At the same time, the IDM controls the low beam through the vehicle's combination switch module to gradually increase the light intensity and illumination distance at the current lighting speed until the low beam is fully turned on.

[0077] Exemplarily, after the high beam is fully turned off and the low beam is fully turned on, the IDM controls the high beam icon in the display screen of the ICM to turn off, and controls the indicator light of the IHBC to remain in a white lighting state.

[0078] In a possible implementation, after the intelligent high beam function is turned on, the intelligent high beam function is continuously monitored. If the IDM detects that the high beam cannot be controlled or the high beam control is incorrect, the indicator light of the IHBC is controlled to light up in red and flash for a certain period of time, and the text message of the intelligent high beam function failure is displayed on the display screen of the ICM. At the same time, the soft switch corresponding to the intelligent high beam is controlled by the ICM to be turned off and grayed out. Optionally, the certain period of time can be set to 3 seconds.

[0079] Optionally, after the intelligent high beam function is turned on, an eighth detection result, a ninth detection result, a tenth detection result and an eleventh detection result are obtained, the eighth detection result is used to indicate whether the wiper is in a high gear, the ninth detection result is used to indicate whether the vehicle's driving speed is within a second preset range, the tenth detection result is used to indicate whether the steering wheel speed is greater than a speed threshold, and the eleventh detection result is used to indicate whether the high beam switch is turned on; in response to the eighth detection result indicating that the wiper is in a high gear, the ninth detection result indicating that the vehicle's driving speed is within the second preset range, and the sixth detection result indicating that the front-view camera is faulty or blocked, the intelligent high beam function is controlled to be interrupted after a preset time; in response to the tenth detection result indicating that the steering wheel speed is greater than the speed threshold, the eleventh detection result indicating that the high beam switch is turned on, and the third detection result indicating that the rear fog lights of the vehicle are on, the intelligent high beam function is controlled to be interrupted immediately.

[0080] Next, examples are given for the methods of obtaining each test result.

[0081] (1) Obtaining the eighth test result

[0082] Exemplarily, the eighth detection result is used to indicate whether the wiper is in a high gear, and obtaining the eighth detection result includes: the IDM obtains the state of the vehicle wiper through the ZCU_L, wherein the state of the wiper includes but is not limited to a high gear, a low gear, an abbreviated gear, and an off gear. If it is detected that the wiper is in a high gear, the eighth detection result indicates that the wiper is in a high gear.

[0083] (2) Obtain the ninth test result

[0084] In a possible implementation, the ninth detection result is used to indicate whether the driving speed of the vehicle is within the second preset range, and obtaining the ninth detection result includes: comparing the driving speed of the vehicle with the speed threshold corresponding to the third preset range, and if the driving speed of the vehicle is within the speed threshold corresponding to the third preset range, the ninth detection result indicates that the driving speed of the vehicle is within the third preset range. Optionally, the speed threshold corresponding to the third preset range can be set based on experience, for example, it can be set to 30 kilometers per hour-150 kilometers per hour.

[0085] (3) Obtain the tenth test result

[0086] Exemplarily, the tenth detection result is used to indicate whether the rotation speed of the steering wheel is greater than the rotation speed threshold, and obtaining the ninth detection result includes: the IDM obtains the rotation speed of the steering wheel through the EPS, and compares the obtained rotation speed of the steering wheel with the rotation speed threshold, and if the rotation speed of the steering wheel is greater than the rotation speed threshold, the tenth detection result indicates that the rotation speed of the steering wheel is greater than the rotation speed threshold. Optionally, the rotation speed threshold can be set based on experience.

[0088] Optionally, the eleventh detection result is used to indicate whether the high beam switch is on. Obtaining the eleventh detection result includes: IDM obtaining the on / off status of the high beam switch through ETRS, and if it is detected that the on / off status of the high beam switch is that the high beam is on, the eleventh detection result indicates that the high beam switch is on.

[0089] In a possible implementation, after determining the eighth detection result and the ninth detection result, if the eighth detection result indicates that the wiper is in high gear, the ninth detection result indicates that the vehicle's driving speed is within a second preset range, and the sixth detection result indicates that the front-view camera is faulty or blocked, the IDM controls the intelligent high beam function to be interrupted after a preset time.

At the same time, the IDM controls the low beam through the vehicle's combination switch module to gradually increase the light intensity and illumination distance at the current lighting speed until the low beam is fully turned on.

[0092] In a possible implementation, in response to a fault in the intelligent high beam function, the vehicle power is in the OFF state, the vehicle exits the startup state and the vehicle gear is in the D gear, and the intelligent high beam function is exited. Exemplarily, if a fault in the intelligent high beam function is detected, the vehicle power is switched to the OFF state, the vehicle exits the startup state and the vehicle gear is in the D gear, and the IDM controls the vehicle to exit the intelligent high beam function.

[0093] For example, after exiting the high beam function, the IDM controls the left front high beam through ZCU_L to gradually reduce the light intensity and illumination distance at the current extinguishing speed until the left front high beam is completely extinguished; sends a request to VCCM to control the right front high beam to extinguish through ZCU_L, and controls the right front high beam through VCCM to gradually reduce the light intensity and illumination distance at the current extinguishing speed until the right front high beam is completely extinguished. At the same time, the IDM controls the low beam through the vehicle's combination switch module to gradually increase the light intensity and illumination distance at the current lighting speed until the low beam is fully turned on.
