When the following description refers to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The implementations described in the following exemplary embodiments do not represent all implementations consistent with the present application.

[0079] The vehicle is equipped with an AFS system with intelligent adjustment function. It is an advanced lighting technology that can automatically adjust the direction and range of the headlight beam according to the vehicle's speed and steering angle to improve the safety and visibility of the vehicle when driving at night.

[0080] Traditional AFS systems usually rely on the steering wheel angle to adjust the deflection angle of the headlights to adapt to the vehicle's driving on a curve. When the vehicle enters a curve, the steering wheel angle is monitored to analyze the vehicle's driving status and the deflection angle of the headlights is adjusted accordingly.

[0081] However, relying solely on the steering wheel angle may result in inaccurate calculation of the headlight deflection angle, thereby affecting the safety of the vehicle's nighttime driving.

The following specific embodiments can be combined with each other, and the same or similar concepts or processes may not be repeated in some embodiments. The embodiments of the present application will be described below in conjunction with the accompanying drawings.

[0084] Figure 1 A schematic diagram of a vehicle headlight control method provided in an embodiment of the present application Figure 1 .like Figure 1 As shown, the method includes:

[0085] S101. Obtain vehicle target parameters.

[0086] In an embodiment of the present application, an executor of a vehicle headlight control method may be an electronic control unit (ECU) in a vehicle. This control unit may be a controller specially designed for the vehicle headlight control method, or may be an existing AFS control unit in the vehicle, and no specific limitation is made here.

[0087] The vehicle target parameter includes at least one of the following: vehicle speed, steering wheel angle, ambient light intensity, ambient rainfall, vehicle height, vehicle front axle load, and vehicle rear axle load.

[0088] Specifically, the ECU can obtain data collected by multiple sensors through the Controller Area Network (CAN) bus, such as vehicle speed collected by the vehicle speed sensor; steering wheel angle collected by the steering wheel angle sensor; ambient light intensity collected by the photosensitive sensor; ambient rainfall collected by the rain sensor; vehicle height collected by the vehicle height sensor; vehicle front axle load and vehicle rear axle load collected by the axle load sensor (load sensor or pressure sensor) and other vehicle target parameters.

[0089] S102: Determine headlamp parameters according to vehicle target parameters.

[0090] In the embodiment of the present application, the headlight parameters include at least one of the following: headlight deflection angle, headlight pitch angle, and headlight intensity. The headlight deflection angle is related to the vehicle speed and the steering wheel angle. The headlight pitch angle is related to the vehicle height, the vehicle front axle load, and the vehicle rear axle load. The headlight intensity is negatively correlated with the ambient light intensity, and the headlight intensity is positively correlated with the ambient rainfall.

[0091] The headlamp deflection angle specifically refers to the angle at which the headlamp's emitted light is deflected to the left or right compared to the front of the vehicle body; the headlamp pitch angle specifically refers to the angle at which the headlamp's emitted light is deflected to the up or down direction compared to the front of the vehicle body; the headlamp intensity specifically refers to the light intensity of the headlamp.

[0092] Specifically, the ECU can determine the headlight deflection angle based on the vehicle speed and steering wheel angle; determine the headlight pitch angle based on the vehicle height, the vehicle front axle load and the vehicle rear axle load; and determine the headlight intensity based on the ambient light intensity and ambient rainfall.

[0093] S103: Control the headlights according to the headlight parameters.

[0094] Specifically, the ECU can control the deflection angle, pitch angle and light intensity of the headlights according to the headlight parameters, thereby improving the safety of the vehicle's night driving.

[0095] The present embodiment provides a vehicle headlight control method, the method comprising: first, obtaining vehicle target parameters, the vehicle target parameters including at least one of the following: vehicle speed, steering wheel angle, ambient light intensity, ambient rainfall, vehicle height, vehicle front axle load and vehicle rear axle load; then, determining headlight parameters according to the vehicle target parameters, the headlight parameters including at least one of the following: headlight deflection angle, headlight pitch angle and headlight intensity, the headlight deflection angle is related to vehicle speed and steering wheel angle, the headlight pitch angle is related to vehicle height, vehicle front axle load and vehicle rear axle load, the headlight intensity is negatively correlated to ambient light intensity, and the headlight intensity is positively correlated to ambient rainfall; then, controlling the headlight according to the headlight parameters.

[0096] The following technical effects are achieved: by acquiring multiple vehicle factors and environmental factors such as vehicle speed, steering wheel angle, ambient light intensity, ambient rainfall, vehicle height, vehicle front axle load and vehicle rear axle load collected by multiple sensors, the headlight parameters can be determined more comprehensively and accurately, thereby realizing intelligent control of the headlights, improving the safety and visibility of the vehicle when driving at night, and providing users with a more reliable and comfortable driving experience; by utilizing data collected by multiple sensors, a variety of vehicle target parameters can be obtained, providing reliable data guarantee for calculating the vehicle's headlight parameters.

[0097] Figure 2 A schematic diagram of a vehicle headlight control method provided in an embodiment of the present application Figure 2 In one possible example, Figure 2 As shown, in this embodiment Figure 1 Based on the embodiment, how to determine the headlamp parameters and how to control the headlamp according to the headlamp parameters are described in detail. Figure 2 As shown, the method includes:

[0098] S201. Obtain vehicle speed, current gear position, and headlight status.

[0099] Specifically, to ensure that the operation of AFS does not affect the normal driving of the vehicle, before obtaining the vehicle's target parameters, the ECU can first obtain the vehicle's current speed, the vehicle's current gear, and the status of the vehicle's headlights through the CAN bus to determine whether the vehicle's headlights can be intelligently controlled.

[0100] S202: When the vehicle speed is greater than 0, the current gear is not reverse gear, and the headlight state is on, enter the headlight intelligent control mode.

[0101] Specifically, when the vehicle speed is 0, or the current gear is reverse gear, or the headlight status is off, the ECU does not control the AFS to work, that is, the vehicle's AFS function is in the off state to ensure the normal driving safety of the vehicle.

[0102] When the vehicle's headlights are on and the vehicle is moving forward, the ECU can control the AFS to work, that is, control the vehicle's AFS function to turn on and put the vehicle into the headlight intelligent control mode.

[0103] Furthermore, in order to ensure the accuracy of the headlamp angle adjustment when the ECU controls the AFS, a fault detection process can be performed on the headlamp each time the AFS is turned on. The fault detection process includes: driving the headlamp to the right to the maximum right deflection angle, driving the headlamp to the left to the maximum left deflection angle, and driving the headlamp to the right to 0 degree. If an abnormality occurs during the fault detection process, a fault prompt message is displayed on the vehicle's display device. That is, after the AFS is started, the ECU can be initialized.

[0104] Figure 3 This is a schematic diagram of a vehicle headlight dimming motor group motion framework provided in an embodiment of the present application. Figure 3 As shown in the figure, the specific steps of performing the fault detection process on the headlight, that is, initializing the ECU, are as follows:

[0105] First, the ECU drives the dimming motor groups 30 of the left and right headlights to move to the right at the same time, until they reach the right mechanical stop point 302 of the dimming motor group 30; then, the ECU drives the dimming motor groups 30 of the left and right headlights to move to the left at the same time, until they reach the left mechanical stop point 303 of the dimming motor group 30; then, the ECU drives the dimming motor groups 30 of the left and right headlights to move to the right at the same time, until they reach the mechanical zero position 301 of the dimming motor group 30.

[0106] Among them, the right mechanical stop point 302 refers to the rightmost position when the dimming motor group 30 runs to the right; the left mechanical stop point 303 refers to the leftmost position when the dimming motor group 30 runs to the left; the mechanical zero point position 301 refers to the position when the output light of the headlamp can be directed to the front of the vehicle body, that is, the position where the deflection angle of the turn signal is 0.

[0107] Furthermore, during the operation of AFS, the ECU can simultaneously detect whether the operation of AFS and related components are working properly. If a fault occurs, the dimming motor group 30 can be controlled to move to the mechanical zero position 301 to prevent the deflection of the headlights from affecting the drivers of other vehicles on the road. The ECU can also send messages to display devices such as the dashboard of the vehicle through the CAN bus to activate corresponding warning lights or voice prompts on the display devices such as the dashboard to remind the driver that the AFS system has a fault and ask the driver to drive carefully and repair it as soon as possible, thereby improving the driving safety of the vehicle.

[0108] S203: Under the headlamp intelligent control mode, obtain vehicle target parameters.

[0109] S203 is similar to S101 and will not be described in detail in this embodiment.

[0110] S204: When the ambient rainfall is greater than or equal to a first rainfall threshold, and / or the ambient light intensity is less than or equal to a preset light threshold, set the headlight intensity to a first intensity.

[0111] Specifically, the ECU can set the headlamp intensity to the first intensity, the second intensity, and the third intensity in the order of the intensity of the emitted light from strong to weak; and can divide the ambient light intensity into three levels of weak, medium, and strong according to the preset standard; and can also divide the ambient rainfall into three levels of small, medium, and large according to the preset standard. Then, the ECU can control the headlamp intensity according to the ambient light intensity and ambient rainfall actually collected by the sensor around the vehicle body.

[0112] Specifically, when the ambient rainfall is greater than or equal to the first rainfall threshold, it indicates that the ambient rainfall around the vehicle body belongs to the heavy rainfall level. In this case, no matter how much the ambient light intensity is or what level it belongs to, the headlamp intensity is set to the first intensity. When the ambient light intensity is less than or equal to the preset light threshold, it indicates that the ambient light intensity around the vehicle body belongs to the weak light level. In this case, no matter how much the ambient rainfall is or what level it belongs to, the headlamp intensity can be set to the first intensity.

[0113] S205: When the ambient rainfall is less than the first rainfall threshold, the ambient rainfall is greater than or equal to the second rainfall threshold, and the ambient light intensity is greater than the preset light threshold, set the headlight intensity to the second intensity.

[0114] In the embodiment of the present application, the second rainfall threshold is smaller than the first rainfall threshold, and the second intensity is smaller than the first intensity.

[0115] Specifically, when the ambient rainfall is less than the first rainfall threshold and the ambient rainfall is greater than or equal to the second rainfall threshold, it indicates that the ambient rainfall around the vehicle body belongs to this level of rainfall; when the ambient light intensity is greater than the preset light threshold, it indicates that the ambient light intensity around the vehicle body belongs to either the medium light level or the strong light level.

[0116] That is, when the ambient rainfall is medium and the ambient light intensity is medium or strong, the ECU can set the headlight intensity to the second intensity.

[0117] S206: When the ambient rainfall is less than the second rainfall threshold and the ambient light intensity is greater than the preset light threshold, set the headlight intensity to a third intensity.

[0118] In the embodiment of the present application, the third strength is less than the second strength.

[0119] Specifically, when the ambient rainfall is less than the second rainfall threshold, it indicates that the ambient rainfall around the vehicle body belongs to the small rainfall level; when the ambient light intensity is greater than the preset light threshold, it indicates that the ambient light intensity around the vehicle body belongs to either the medium light level or the strong light level.

[0120] That is to say, when the ambient rainfall is small and the ambient light intensity is medium or strong, the ECU can set the headlight intensity to the third intensity.

[0121] S207: Determine the center of mass position of the vehicle according to the front axle load and the rear axle load of the vehicle.

[0122] Specifically, the ECU can determine the headlight pitch angle according to the vehicle front axle load and the vehicle rear axle load. Specifically, first, the vehicle wheelbase L can be obtained through the CAN bus; then, the vehicle rear axle load W can be calculated. r The product of the vehicle's wheelbase L and the vehicle's front axle load W f The vehicle rear axle load W r Finally, by calculating the first ratio of the product to the sum of the front and rear axle loads of the vehicle, the center of mass position d of the vehicle, that is, the distance of the center of mass position relative to the front axle, is obtained. The specific calculation of the center of mass position is as follows:

[0123]

[0124] S208, calculating the pitch angle of the vehicle head according to the position of the vehicle center of mass, the vehicle wheelbase, and the height difference between the front and rear axles of the vehicle.

[0125] Specifically, the ECU can also obtain the height difference h between the front and rear axles of the vehicle through the CAN bus, and the specific calculation formula for the pitch angle of the vehicle head is as follows:

[0126]

[0127] in, is the pitch angle of the vehicle front.

[0128] S209: Determine the pitch angle of the headlight according to the pitch angle of the vehicle front.

[0129] Specifically, the ECU can adjust the pitch angle of the headlights according to the pitch angle of the vehicle front to ensure the appropriate lighting range and angle of the headlights.

[0130] In a possible implementation, the pitch angle of the headlights may change synchronously with the pitch angle of the front of the vehicle, that is, the pitch angle of the headlights is consistent with the calculated pitch angle of the front of the vehicle.

[0131] S210: When the vehicle speed is less than or equal to a first vehicle speed threshold, and / or the steering wheel angle is less than or equal to a first angle threshold, setting the headlight deflection angle to 0.

[0132] Specifically, the ECU can determine the deflection angle of the headlights in the left and right directions based on the vehicle speed and steering wheel angle.

[0133] Table 1 Correspondence between headlight deflection angle, vehicle speed and steering wheel angle

[0134]

[0135] Table 1 schematically shows the corresponding headlight deflection angle at different vehicle speeds and different steering wheel angles. The direction of the headlight deflection angle is consistent with the direction of the steering wheel angle. The steering wheel angle in the table is the steering wheel angle. The positive and negative signs before the steering wheel angle are used to indicate the left and right directions of the steering wheel angle. It can be positive for turning left and negative for turning right; or positive for turning right and negative for turning left. There is no specific restriction here. The vehicle speed unit is kilometers per hour (Km / h).

[0136] Specifically, as shown in Table 1, when the vehicle speed is less than or equal to 10 km / h, and / or the steering wheel angle is less than or equal to 20 degrees, the ECU may set the headlight deflection angle to 0 degrees.

[0137] S211. When the vehicle speed is greater than a first vehicle speed threshold and the steering wheel angle is greater than or equal to a second steering angle threshold, setting the headlight deflection angle to a maximum deflection angle of the headlight deflection angle.

[0138] In the embodiment of the present application, the second turning angle threshold is greater than the first turning angle threshold.

[0139] Specifically, as shown in Table 1, when the vehicle speed is greater than 10 km / h and the steering wheel angle is greater than or equal to 140 degrees, the ECU can set the headlight deflection angle to the maximum deflection angle of the headlight deflection angle (ie, 13 degrees).

[0140] S212: When the vehicle speed is between the first vehicle speed threshold and the second vehicle speed threshold, and the steering wheel angle is between the first turning angle threshold and the second turning angle threshold, determine the headlight deflection angle according to the vehicle speed and the steering wheel angle.

[0141] In the embodiment of the present application, the second vehicle speed threshold is greater than the first vehicle speed threshold, and the magnitude of the headlight deflection angle is positively correlated to the vehicle speed and the magnitude of the steering wheel angle.

[0142] Specifically, as shown in Table 1, when the vehicle speed is between 10Km / h and 30Km / h, and the steering wheel angle is between 20 degrees and 140 degrees, the ECU can determine the size of the headlight deflection angle according to the vehicle speed and the steering wheel angle. At this time, the size of the headlight deflection angle is positively correlated with the vehicle speed and the steering wheel angle.

[0143] S213: When the vehicle speed is greater than the second vehicle speed threshold and the steering wheel angle is between the first angle threshold and the second angle threshold, determine the headlight deflection angle according to the vehicle speed and the steering wheel angle.

[0144] In the embodiment of the present application, the size of the headlight deflection angle is positively correlated to the size of the steering wheel angle, and the headlight deflection angle is negatively correlated to the vehicle speed.

[0145] Specifically, as shown in Table 1, when the vehicle speed is greater than 30 km / h and the steering wheel angle is between 20 and 140 degrees, the ECU can determine the size of the headlight deflection angle according to the vehicle speed and the steering wheel angle. At this time, the size of the headlight deflection angle is positively correlated with the size of the steering wheel angle, and the size of the headlight deflection angle is negatively correlated with the vehicle speed.

[0146] S214: Acquire an actual deflection angle and an actual pitch angle of the headlight.

[0147] Specifically, after determining the headlamp intensity, the headlamp pitch angle and the headlamp deflection angle, the ECU can control the headlamp according to the headlamp parameters. Specifically, first, the ECU can obtain the actual deflection angle and the actual pitch angle of the headlamp through the CAN bus to compare with the headlamp pitch angle and the headlamp deflection angle determined by the ECU.

[0148] S215: When a first difference between the actual deflection angle of the headlight and the deflection angle of the headlight is greater than or equal to an error threshold, adjust the actual deflection angle of the headlight according to the first difference.

[0149] Specifically, the ECU may then calculate a first difference between the actual deflection angle of the headlight and the determined deflection angle of the headlight, and when the first difference is greater than or equal to an error threshold, adjust the actual deflection angle of the headlight by the angle indicated by the first difference.

[0150] Furthermore, the adjustment process of the actual deflection angle of the headlamp may be implemented once or multiple times. For example, after the adjustment is completed, the actual deflection angle of the headlamp may be obtained again, and the first difference may be calculated again. If the first difference is still greater than or equal to the error threshold, the actual deflection angle of the headlamp may be adjusted again until the first difference is less than the error threshold.

[0151] S216: When a second difference between the actual pitch angle of the headlight and the pitch angle of the headlight is greater than or equal to an error threshold, adjust the actual pitch angle of the headlight according to the second difference.

[0152] Specifically, the ECU may calculate a second difference between the actual pitch angle of the headlight and the determined pitch angle of the headlight, and when the second difference is greater than or equal to the error threshold, adjust the actual pitch angle of the headlight by the angle indicated by the second difference.

[0153] Furthermore, the adjustment process of the actual pitch angle of the headlamp may be implemented once or multiple times. For example, after the adjustment is completed, the actual pitch angle of the headlamp may be obtained again, and the second difference may be calculated again. If the second difference is still greater than or equal to the error threshold, the actual pitch angle of the headlamp may be adjusted again until the second difference is less than the error threshold.

[0154] A vehicle headlamp control method provided in an embodiment of the present application ensures the normal driving safety of the vehicle by controlling the AFS function of the vehicle to be in a turned-off state when the vehicle is not in a forward state or the headlamp state is in a turned-off state; ensures the accuracy of the headlamp angle adjustment when the AFS is controlled by performing a fault detection process on the headlamp each time the AFS is turned on; during the operation of the AFS, the operation process of the AFS and whether related components are working normally are simultaneously detected, and when a fault state occurs, the dimming motor group is controlled to move to a mechanical zero position, thereby avoiding the deflection of the headlamp to affect the drivers of other vehicles driving on the road; sends a message to a display device such as a dashboard of the vehicle through a CAN bus, and on the display device such as the dashboard, activates a corresponding prompt light or voice prompt information, etc., to remind the driver that the AFS system has a fault, thereby improving the driving safety of the vehicle.
