[0066] At present, the traditional vehicle lamp control method is usually based on the data collected by the vehicle body height sensor to control the illumination height of the vehicle lamp. However, in actual application, due to the fitting deviation of the sensor data by the hardware and software of the chassis suspension, the complexity of the actual road conditions, and the influence of individual driving habits, the signal transmitted by the vehicle body height sensor is often not stable, so that the vehicle is prone to frequent up and down adjustment of the lamp height during driving due to the instability of the sensor data. This not only easily distracts the driver's attention during driving, and the driving comfort of the driver is not high; moreover, in special driving conditions, this method often cannot control the illumination height of the vehicle lamp in a timely manner, so that the illumination range of the vehicle lamp during driving will be sharply increased or decreased, the illumination effect is poor, and the stability of the illumination range of the vehicle lamp is not high.

[0067] Therefore, in the embodiments of the present application, a vehicle lamp control method, system, device and vehicle based on vehicle speed are provided, wherein the control method is based on the vehicle body mode representing the speed of the change of the vehicle body posture of the target vehicle during driving, and adjusts the lamp angle of the target vehicle in combination with the vehicle body posture data, so that the adjusted angle can effectively correspond to the speed of the change of the vehicle body posture, thereby reducing the frequent adjustment of the illumination height of the vehicle lamp, improving the stability of the vehicle lamp illumination and improving the driving comfort of the driver. In addition, the control method based on the vehicle body mode representing the speed of the change of the vehicle body posture of the target vehicle during driving can more accurately obtain the urgency of the demand of the target vehicle for adjusting the illumination height of the vehicle lamp, thereby improving the timeliness of the vehicle lamp illumination.

[0070] FIG. 1 is an optional flowchart of a vehicle lamp control method based on vehicle speed according to an embodiment of the application. The method of FIG. 1 can include, but is not limited to, steps S110 to S130.

[0071] In step S110, speed data and body posture data of a target vehicle are acquired, and a current body mode is determined.

[0072] In the embodiment of the application, the speed data and the body posture data of the target vehicle can be obtained by corresponding sensors, the speed data includes a vehicle speed signal and an acceleration signal, and the current body mode can be determined according to a mode determined by the last lamp angle adjustment.

[0073] In step S120, the current body mode is updated according to the speed data to obtain an updated body mode.

[0074] Referring to FIGS. 2 and 3, in some embodiments, the step S120 of updating the current body mode according to the speed data to obtain an updated body mode includes:

[0075] In step S121, a preset acceleration threshold and a vehicle speed threshold are acquired.

[0076] In step S122, the acceleration threshold and the acceleration signal are compared to obtain an acceleration comparison result.

[0077] In step S123, if the acceleration comparison result is that the acceleration signal is greater than the acceleration threshold, the current body mode is updated to a dynamic mode; or if the acceleration comparison result is that the acceleration signal is less than or equal to the acceleration threshold, the vehicle speed threshold and the vehicle speed signal are compared to obtain a vehicle speed comparison result.

[0078] If the comparison result of the vehicle speed is that the vehicle speed signal is greater than the vehicle speed threshold, the current vehicle body mode is updated as the normal mode; or if the comparison result of the vehicle speed is that the vehicle speed signal is less than or equal to the vehicle speed threshold, the current vehicle body mode is updated as the slow mode.

[0079] In the embodiments of the present application, the specific values of the acceleration threshold and the vehicle speed threshold can be set according to actual conditions. For example, the acceleration threshold can be any one of 8 m / s 2 , 10 m / s 2 , 12 m / s 2 , etc., and the vehicle speed threshold can be any one of 15 km / h, 20 km / h, 25 km / h, etc. The examples in the present application are for illustration only and do not limit the present application in any way.

[0080] It can be understood that when the current acceleration signal of the target vehicle is greater than the acceleration threshold, it indicates that the vehicle is in a state of rapid acceleration or rapid deceleration, and the vehicle body posture changes the fastest, so the current vehicle body mode can be updated as the dynamic mode. When the current acceleration signal of the target vehicle is less than or equal to the acceleration threshold, it indicates that the vehicle is not in a state of rapid acceleration or rapid deceleration, and at this time, the size of the vehicle speed signal and the vehicle speed threshold can be compared. If the vehicle speed signal is greater than the vehicle speed threshold, it indicates that the vehicle speed is high, and the vehicle body posture changes fast, so the current vehicle body mode can be set as the normal mode. If the vehicle speed signal is less than or equal to the vehicle speed threshold, it indicates that the vehicle speed is slow, and the vehicle body posture changes slowly, so the current vehicle body mode can be set as the slow mode.

[0081] In step S130, the lamp angle of the target vehicle is adjusted according to the vehicle body posture data and the updated vehicle body mode.

[0082] The speed data is used to record the vehicle speed signal and the acceleration signal of the target vehicle in the driving process, and the vehicle body mode is used to represent the fast or slow degree of the vehicle body posture change of the target vehicle in the driving process.

[0083] Referring to FIG. 4, in some embodiments, the step S130 of adjusting the lamp angle of the target vehicle according to the vehicle body posture data and the updated vehicle body mode comprises:

[0084] In step S131, a preset filter window is obtained, the filter window comprises a first window, a second window and a third window, the first window corresponds to the dynamic mode, the second window corresponds to the normal mode, and the third window corresponds to the slow mode.

[0085] Further, the first window is smaller than the second window, and the second window is smaller than the third window.

[0086] In the embodiments of the present application, the filtering window includes a first window, a second window and a third window, the first window is a filtering window used by the vehicle when the vehicle body posture changes fastest, and the second window and the third window are similar and can be simply analogized.

[0087] It can be understood that, by using the filtering window corresponding to the vehicle body mode to filter the vehicle body posture data, the filtering window used can meet the lighting requirements of the vehicle lamp under the current speed and acceleration of the target vehicle.

[0088] Specifically, the first window in the embodiments of the present application can be smaller than the second window, and the second window can be smaller than the third window, the specific size of the first window can be any one of 8, 10, 12, etc., the size of the second window can be any one of 14, 16, 18, etc., and the third window can be any one of 20, 22, 25, etc., which are only for illustration. It is worth noting that, by using a relatively small first window to analyze the lamp angle of the vehicle body posture data in the dynamic mode, the vehicle ALS system can have a faster real-time response, effectively improving the timeliness of vehicle lighting; and by using a relatively large third window to analyze the lamp angle of the vehicle body posture data in the slow mode, the vehicle ALS system can accurately and stably filter the posture data, thereby reducing the number of times of adjusting the height of the vehicle lamp when adjusting the lamp angle, and keeping the lighting range of the vehicle lamp relatively stable, avoiding affecting the attention of the driver when driving, and improving the stability and driving comfort of the vehicle lamp lighting.

[0089] In step S132, the lamp angle of the vehicle body posture data is analyzed according to the filtering window to obtain an adjustment angle.

[0090] Referring to FIG. 5, further, the step S132 of analyzing the lamp angle of the vehicle body posture data according to the filtering window to obtain an adjustment angle includes:

[0091] A1, window filtering the vehicle body posture data according to the filtering window to obtain filtered posture data;

[0092] Referring to FIG. 6, further, the A1 of window filtering the vehicle body posture data according to the filtering window to obtain filtered posture data includes:

[0093] A11, obtaining a storage array, the storage array being used to store historical posture data of the target vehicle;

[0094] In the embodiments of the present application, the storage array includes a first storage array, a second storage array and a third storage array, wherein the array size of the first storage array corresponds to the window size of the first window, the array size of the second storage array corresponds to the window size of the second window, and the array size of the third storage array corresponds to the window size of the third window. In addition, for the historical posture data of the storage array, it can be the body posture data directly collected by the body height sensor of the target vehicle in the initial driving process of the target vehicle; and after the target vehicle has driven for a period of time, the historical posture data can be the adjacent filtered posture data at the current driving moment.

[0095] A12, performing mean replacement on the body posture data according to the filter window and the storage array to obtain the filtered posture data.

[0096] Further, the A12, performing mean replacement on the body posture data according to the filter window and the storage array to obtain the filtered posture data, includes:

[0097] A121, obtaining the current index value and index data of the storage array, wherein the index value corresponds to the index data;

[0098] A122, if the current index value is less than the filter window, performing first replacement update on the index data in the storage array according to the body posture data and the current index value to obtain an updated storage array, then calculating the data mean value of the updated storage array according to the filter window to obtain the filtered posture data; or, if the current index value is greater than or equal to the filter window, performing reset update on the current index value to obtain an updated index value, then performing second replacement update on the index data in the storage array according to the body posture data and the updated index value to obtain the updated storage array, and calculating the data mean value of the updated storage array according to the filter window to obtain the filtered posture data.

[0099] In the embodiments of the present application, taking the updated vehicle body mode as the dynamic mode as an example, the mean replacement can first determine a first storage array corresponding to the first window, a current index value of the first storage array, and index data corresponding to the current index value. Then, the current index value is compared with the window size of the first window. If the current index value is less than the window size of the filter window, it indicates that the first storage array still has index data that has not been replaced and updated in the current array round. At this time, the index data corresponding to the current index value in the first storage array is replaced by the current vehicle body posture data to obtain an updated first storage array. The updated first storage array includes the current vehicle body posture data and historical posture data corresponding to other index values. Then, the average value of all posture data in the first storage array is calculated to obtain the filtered posture data. Alternatively, if the current index value is greater than or equal to the window size of the filter window, it indicates that the first storage array does not have index data that has not been replaced and updated in the current array round. At this time, the current index value can be reset so that the updated index value points to the first array element in the first storage array. The second replacement update is similar to the content of the first replacement update. The present application will not be repeated here.

[0100] It should be noted that, since the vehicle body posture data collected by the vehicle is real-time, the current index value can be updated after the first replacement update, so that the first replacement update can be performed according to the corresponding index value when the next vehicle body posture data is subjected to mean replacement. The remaining normal mode and slow mode are similar to the content of the dynamic mode described above, and the present application will not be repeated here.

[0101] A2, performing angle conversion processing on the filtered posture data to obtain the adjustment angle.

[0102] Referring to FIG. 7, further, the A2, performing angle conversion processing on the filtered posture data to obtain the adjustment angle, includes:

[0103] A21, obtaining a vehicle body parameter of the target vehicle;

[0104] A22, performing pitch angle conversion on the filtered posture data to obtain a vehicle body pitch angle of the target vehicle;

[0105] A23, performing angle calculation on the vehicle body pitch angle according to the vehicle body parameter to obtain the adjustment angle.

[0106] In the embodiment of the present application, the body parameter of the target vehicle belongs to the calibration parameter of the vehicle, which can be obtained from the vehicle factory information; after the filtered attitude data is obtained, the filtered attitude data can be input into the ALS system of the vehicle for angle calculation, so as to calculate the body pitch attitude change (i.e. the body pitch angle); then, the body pitch angle and the body parameter are combined to calculate the angle required for adjusting the vehicle lamp, and the specific implementation can be realized by controlling the motor rotation angle, that is, the adjustment angle in the embodiment of the present application can be the angle required for adjusting the vehicle lamp or the angle required for adjusting the motor.

[0107] In step S133, the lamp angle of the target vehicle is adjusted according to the adjustment angle.

[0108] Referring to FIG. 8, further, the step S133 of adjusting the lamp angle of the target vehicle according to the adjustment angle comprises:

[0109] B1, obtaining a difference threshold value;

[0110] B2, obtaining a historical angle according to the current adjustment angle, the historical angle being the last adjustment angle;

[0111] B3, differentially comparing the historical angle and the current adjustment angle to obtain a differential comparison result;

[0112] B4, if the differential comparison result is that the absolute value of the difference between the historical angle and the current adjustment angle is less than the difference threshold value, the lamp angle of the target vehicle is maintained; or, if the differential comparison result is that the absolute value of the difference between the historical angle and the current adjustment angle is greater than or equal to the difference threshold value, the lamp angle of the target vehicle is adjusted according to the current adjustment angle.

[0113] In the embodiment of the present application, the difference threshold value can be an angle threshold value, and the specific value can be any one of 0.1°, 0.2°, 0.3°, etc., which is only illustrative in the present application. After obtaining the difference threshold value, the current adjustment angle, i.e. the adjustment angle output by the vehicle ALS system at the current time, and the historical angle, i.e. the adjustment angle output by the vehicle ALS at the last time, can be obtained; then, the current adjustment angle and the historical angle are differentially compared, if the absolute value of the difference between the historical angle and the current adjustment angle is less than the difference threshold value, it indicates that the attitude change of the vehicle body is relatively small, and the illumination range of the vehicle lamp does not need to be adjusted, so the lamp angle of the target vehicle can be maintained, that is, the lamp angle of the target vehicle is made to be the same as the historical angle; or, if the absolute value of the difference between the historical angle and the current adjustment angle is greater than or equal to the difference threshold value, it indicates that the attitude of the vehicle body has changed obviously, and the lamp angle of the target vehicle needs to be adjusted to the adjustment angle.

[0114] It should be noted that the step S133 in the embodiment of the present application can effectively prevent the occurrence of the shaking situation of the vehicle lamp, specifically, due to respective environmental factors and vehicle reasons, the vehicle may also change the reading of the sensor when it is stationary on the flat ground, that is, the collected vehicle body posture data may change slightly, and the change is more dramatic in other driving situations, so that the obtained adjustment angle has certain noise, and the shaking situation of the vehicle lamp is prone to occur in the adjustment process of the vehicle lamp. The embodiment of the present application can further reduce the fluctuation of the illumination range of the vehicle lamp and improve the stability of the vehicle lamp illumination while adjusting the lamp angle based on the vehicle body mode, so that the target vehicle can still have a stable effect when facing slight changes in the dynamic mode, normal mode and slow mode.

[0116] The acquisition unit 310 is configured to acquire speed data and vehicle body posture data of a target vehicle, and a current vehicle body mode;
