Technical Field

[0001] This application relates to the field of vehicle technology, and in particular to a method, device, and vehicle-side control equipment for controlling vehicle daytime running lights. Background Technology

[0002] Daytime running lights, or DRLs for short, are signal lights primarily used during the day to indicate the presence of other vehicles. They are typically installed on the front sides of vehicles. The purpose of DRLs is not to make the driver see the road, but rather to increase the visibility of the vehicle while driving, effectively reducing the risk of accidents and ensuring traffic safety.

[0003] However, adding daytime running lights to motor vehicles inevitably increases energy consumption due to the operation of the daytime running lights.

[0053] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0054] Daytime running lights (DRLs) can effectively improve the visibility of motor vehicles while driving, thereby enhancing driving safety. However, the use of DRLs also increases the energy consumption of motor vehicles. Therefore, how to reduce energy consumption while ensuring the visibility of motor vehicles while driving has become an important issue in current technological development.

[0055] Current daytime running light (DRL) control methods primarily rely on manual operation by the driver. When the driver needs to turn on the DRLs, they can do so by activating the corresponding switch. Additionally, some advanced driver assistance systems (ADAS) can automatically activate the DRLs based on ambient light intensity.

[0056] However, existing daytime running light (DRL) control methods have some problems. First, they rely heavily on manual operation by the driver, which increases the driver's workload and may lead to the driver forgetting to turn on the DRLs, thus affecting driving safety. Second, existing DRL control methods cannot intelligently control the on / off state and brightness of the DRLs based on the actual vehicle status, which increases the vehicle's energy consumption to some extent.

[0057] In one exemplary embodiment, such as Figure 1 As shown, a method for controlling vehicle daytime running lights is provided. This method can be applied to a vehicle, a corresponding server, or a system including both the vehicle and the server, and is implemented through interaction between the vehicle and the server. This application uses the application of this method to a vehicle as an example for illustration, including the following steps 101 to 104. Wherein:

[0058] Step 101: Obtain the status of the current vehicle's daytime running lights and position lights.

[0059] The vehicle can be a new energy vehicle or a traditional gasoline vehicle. Specifically, the new energy vehicle can be a pure electric vehicle or a hybrid electric vehicle. This application does not make any specific restrictions on this.

[0060] Specifically, step 101 is performed to obtain the current status of the vehicle's daytime running lights (DRLs) to determine whether they are on. If they are already on, the steps required to control their activation are not necessary. If the DRLs are found to be off, it is further determined whether they are enabled. If they are enabled, it is determined whether they need to be turned on, and the activation is controlled based on the determination result. If they are disabled, the DRLs' readiness status needs to be monitored again, or the reasons for their absence need to be analyzed, until they are detected as enabled.

[0061] The enabled state of daytime running lights refers to the daytime running lights being in a ready and waiting state to be turned on. When the daytime running lights are in the enabled state, the system can further determine whether the daytime running lights need to be turned on based on the needs, and control the turning on of the daytime running lights based on the determination result.

[0062] If the daytime running lights (DRLs) are detected to be enabled, it means that the DRLs are ready and can receive the command to turn on at any time to activate them. However, this application also provides a condition for determining whether the DRLs are enabled: while the DRLs are enabled, the state of the current vehicle position lights is further determined.

[0063] Position lights on a car are lights that indicate the vehicle's location when turned on. When illuminated, they show the vehicle's outline and indicate its size, allowing other vehicles to distinguish the size and position of the car in low-light conditions.

[0064] Therefore, the functions of position lights and daytime running lights are similar, both serving to improve vehicle visibility. Based on this, in the technical solution provided in this application, the activation of daytime running lights and position lights is mutually exclusive. That is, when position lights are on, daytime running lights cannot be activated; daytime running lights can only be activated when position lights are off. This design ensures improved vehicle visibility while reducing the energy required for both daytime running lights and position lights to be activated simultaneously, thereby reducing vehicle energy consumption.

[0065] It should also be noted that this application does not specify the order in which the daytime running lights status and the position lights status are acquired. The main purpose of executing step 101 is to know that the daytime running lights will be turned on when the position lights are detected to be off.

[0066] Step 102: With the daytime running lights and position lights off, turn on the daytime running lights based on the current vehicle's preset brightness.

[0067] Specifically, after executing step 101 to obtain the status of the current vehicle's daytime running lights and position lights, step 102 can be further executed. If it is determined that both the daytime running lights and position lights are in the off state, then the daytime running lights of the vehicle can be further controlled to be turned on. Therefore, the daytime running lights can be turned on based on the current vehicle's preset brightness, so as to increase the visibility of the corresponding vehicle during driving based on the daytime running lights in the on state, thereby improving driving safety.

[0068] The preset brightness of the daytime running lights of the current vehicle can be set at the factory or set by the user based on the user's needs. This application does not make any specific restrictions on this. This application also does not make any restrictions on the specific brightness value of the preset brightness.

[0069] Step 103: Obtain the current environmental information, vehicle speed information, and steering wheel angle information of the vehicle.

[0070] Specifically, to make the daytime running lights' brightness more suitable for the current vehicle conditions, this application provides an alternative implementation method: after turning on the daytime running lights based on a preset brightness, further execute step 103 to acquire and identify the current vehicle conditions. This specifically includes acquiring environmental information, vehicle speed information, and steering wheel angle information. The steering wheel angle information may include at least the steering wheel's turning direction (deflection direction) and angle (deflection value).

[0071] By acquiring information such as the vehicle's current environment, speed, and steering wheel angle, it is possible to clarify the vehicle's current situation. This allows for the calculation of the target brightness of the daytime running lights based on the vehicle's condition, ensuring that the final target brightness of the daytime running lights is more suitable for the vehicle's situation and preventing the daytime running lights from being too bright or too dim.

[0072] Step 104: Based on environmental information, vehicle speed information, and steering wheel angle information, determine the target brightness of the daytime running lights and adjust the brightness of the daytime running lights to the target brightness.

[0073] Specifically, after obtaining the current vehicle's environmental information, vehicle speed information, and steering wheel angle information in step 103, step 104 can be further executed. That is, based on the environmental information, the vehicle speed information and steering wheel angle information that can be used to obtain the target brightness of the daytime running lights are selected and obtained. Then, based on the environmental information, and / or vehicle speed information, and / or steering wheel angle information, the target brightness of the daytime running lights of the current vehicle is calculated. After determining the target brightness of the daytime running lights, the luminous brightness of the daytime running lights is adjusted based on the target brightness so that the luminous brightness of the daytime running lights in the on state can be updated to the calculated target brightness. In other words, after the daytime running lights are turned on, this application calculates the most suitable target brightness for the daytime running lights, so that the daytime running lights can be adjusted to the most suitable target brightness as soon as possible after being turned on, avoiding the waste of vehicle energy. This is beneficial to improving vehicle safety and reducing the energy consumption of motor vehicles, thereby improving the vehicle's range. In addition, it can also avoid the situation of insufficient initial luminous brightness, so as to ensure the improvement of the daytime running lights' visibility of the vehicle.

[0074] It should be noted that, depending on the current environment of the vehicle, when calculating the target brightness of the daytime running lights, the required data among environmental information, vehicle speed information, and steering wheel angle information may only include one of them, such as only environmental information; or, depending on the environment, any two or all of the three information may be required. This application does not limit this. For example, the target brightness of the daytime running lights can be determined based on all three information, such as environmental information, vehicle speed information, and steering wheel angle information, which helps to further improve the accuracy of the determined target brightness. Furthermore, in complex environments, the target brightness of the daytime running lights may be determined by combining environmental information, vehicle speed information, and steering wheel angle information with other data to achieve a more suitable target brightness. These other data may include traffic flow data.

[0075] The vehicle daytime running lights control method provided in this application obtains the current status of the vehicle's daytime running lights and position lights; when the position lights are off, the daytime running lights are turned on based on a preset brightness of the current vehicle; the method obtains environmental information, vehicle speed information, and steering wheel angle information of the current vehicle; based on the environmental information, vehicle speed information, and steering wheel angle information, the method determines the target brightness of the daytime running lights and adjusts the brightness of the daytime running lights to the target brightness; by first turning on the daytime running lights based on the preset brightness of the current vehicle when the position lights are off, the method can improve the speed of daytime running light activation, thereby quickly improving the vehicle's visibility; and then adjusting the brightness of the daytime running lights to better match the environment, i.e., adjusting the brightness of the daytime running lights to the target brightness, is beneficial to reducing the vehicle's energy consumption. Furthermore, this method achieves automated control of whether the daytime running lights are on or off, which helps reduce the driver's workload and avoids the problem of forgetting to turn the daytime running lights on or off due to driver negligence, thus improving driving safety and contributing to energy conservation and emission reduction in motor vehicles.

[0076] It should be added that, regarding the determination of steering wheel angle information, this application provides an optional implementation method: acquiring data such as the current vehicle's front wheel angle, front wheelbase, turning radius, and steering wheel-to-front wheel angle coefficient; and then determining the current vehicle's steering wheel angle information based on the acquired front wheel angle, front wheelbase, turning radius, and steering wheel-to-front wheel angle coefficient. Of course, this is only one method for determining steering wheel angle information provided by this application, but it is not limited to this method.

[0077] That is, step 103 above can be specifically executed as follows: obtain the current environmental information, vehicle speed information, front wheel angle, front wheel wheelbase, vehicle turning radius, and steering wheel and front wheel angle coefficient; and determine the current vehicle steering wheel angle information based on the front wheel angle, front wheel wheelbase, vehicle turning radius, and steering wheel and front wheel angle coefficient.

[0078] It should be explained that the environmental information includes, for example, whether the vehicle is in daytime or nighttime, sunny or rainy, or whether it is in a tunnel or on a regular road, etc.

[0079] It should also be added that a preset value range can be set for the turning radius of the vehicle body. For example, the turning radius of the vehicle body is greater than or equal to F1 and less than or equal to F2. In this regard, this application provides a selectable value range of 5 meters to 30 meters, that is, the turning radius of the vehicle body is greater than or equal to 5 meters and less than or equal to 30 meters.

[0080] It should also be noted that when calculating the target brightness of daytime running lights, if the calculation involves the vehicle's turning radius, the target turning radius used in the calculation is not necessarily the real-time turning radius of the vehicle. This application provides a method for determining the target turning radius used in calculating the target brightness of daytime running lights: first, determine the real-time speed of the vehicle, and then determine the target turning radius required for calculating the target brightness of daytime running lights based on the real-time speed. In response, this application provides an alternative implementation method where, when the real-time vehicle speed is greater than or equal to 50 km / h, the target turning radius is taken as the maximum value within the corresponding range, for example, a target turning radius of 30 meters. This ensures that the calculated target brightness of the daytime running lights is higher, making it easier for surrounding vehicles to recognize the vehicle and thus avoiding collisions caused by excessive speed, thereby improving vehicle driving safety. Conversely, when the real-time vehicle speed is less than 50 km / h, the target turning radius can be taken as the actual turning radius of the vehicle body. This ensures that the calculated target brightness of the daytime running lights is a suitable brightness, avoiding excessively dim or bright light. This approach ensures that the target brightness of the daytime running lights improves the visibility of the vehicle while also preventing the waste of vehicle energy from turning on the daytime running lights.

[0081] It should be noted that the target turning radius used to calculate the target brightness of the daytime running lights with a vehicle speed of 50 km / h as the node is only one optional implementation method provided by this application, but this application is not limited to it; the vehicle speed node value can be adjusted according to actual needs. In addition to the 50 km / h provided by this application, vehicle speed node values ​​of 60 km / h, 65 km / h, 45 km / h, etc. can also be selected.

[0082] Based on this, regarding the content of "determining the steering wheel angle information of the current vehicle based on the front wheel angle, front wheel wheelbase, vehicle turning radius, and steering wheel and front wheel angle coefficient" mentioned above, this application provides a formula for calculating the steering wheel angle value β in the steering wheel angle information of the current vehicle, including: β=g*φ, sinφ=W / D, then β=g*arcsin(W / D)*(180° / π); where g is the steering wheel and front wheel angle coefficient mentioned above, φ is the front wheel angle mentioned above, W is the front wheel wheelbase mentioned above, and D is the vehicle turning radius mentioned above.

[0083] It should also be noted that the front wheelbase W and the steering wheel angle coefficient g are set at the factory; that is, for the same vehicle model, the front wheelbase W and the steering wheel angle coefficient g are the same. It should be pointed out that the formula for calculating the steering angle value β in the steering wheel angle information of the current vehicle provided in this application is applicable to any vehicle model, as long as the corresponding vehicle model can provide data such as the steering wheel angle coefficient g, the front wheel angle φ, the front wheelbase W, and the vehicle's turning radius D.

[0084] Furthermore, it should be added that step 103 provided in this application involves first calculating the target brightness of the daytime running lights (DRLs), and then adjusting the brightness of the DRLs based on the calculated target brightness. This allows the DRLs to be adjusted to a more suitable target brightness based on a preset brightness. However, this is only one possible implementation method provided by this application. Alternatively, when it is known that the position lights are off, the system can first obtain the current environmental information, vehicle speed information, and steering wheel angle information. Based on these information, the target brightness of the DRLs can be determined, and then the DRLs can be turned on based on the target brightness. In this way, the DRLs can be turned on at the optimal brightness.

[0085] It should also be added that, when the daytime running lights emit light based on the target brightness, the target brightness of the daytime running lights can be further adjusted in real time based on changes in environmental information, vehicle speed information, and steering wheel angle information, so that the target brightness of the daytime running lights can be kept at the most suitable brightness in real time; in addition, the update of the target brightness when the daytime running lights are on can also be based on a preset time period, and this application does not make specific limitations on this.

[0086] In an exemplary embodiment, the vehicle daytime running light control method provided in this application further includes:

[0087] The set of influencing factors for determining the target brightness of daytime running lights is based on environmental information. The set of influencing factors includes one or two of the following three conditions: sunny day, rainy day, and tunnel.

[0088] Specifically, regarding the aforementioned technical content of determining the target brightness of daytime running lights based on environmental information, vehicle speed information, and steering wheel angle information, this application also provides an alternative implementation method: first determining a set of influencing factors for daytime running light brightness based on environmental information. This set of influencing factors may include one influencing factor or multiple influencing factors. For example, the set of influencing factors may include two influencing factors, wherein the influencing factors may specifically include sunny weather, rainy weather, and tunnels.

[0089] To illustrate, compared to sunny days, the target brightness of daytime running lights (DRLs) in rainy weather may also be influenced by the amount of rainfall. Then, based on a defined set of influencing factors, and at least one of vehicle speed and steering wheel angle information, the most suitable target brightness of the DRLs for the current vehicle is calculated. This improves the adaptability of the calculated target brightness of the DRLs to the vehicle's environment and state (including target vehicle speed and steering wheel angle information), thereby further reducing the energy consumption of the vehicle when the DRLs are on, while ensuring the visibility of the vehicle during driving.

[0090] In one exemplary embodiment, based on this, the present application also provides some alternative implementation methods for determining the target brightness of daytime running lights, including:

[0091] When the environmental information representation is in a sunny state, the target brightness of the daytime running lights should be determined based on at least the ambient light intensity, the light intensity threshold, the vehicle speed matching brightness, and the steering wheel angle brightness.

[0092] When the environmental information representation is in a rainy condition, the target brightness of the daytime running lights should be determined based on at least the ambient light intensity, light intensity threshold, vehicle speed matching brightness, steering wheel angle brightness, rainfall, and rain light intensity threshold.

[0093] When the environmental information representation is inside the tunnel, the target brightness of the daytime running lights should be determined based on at least the ambient light intensity, illuminance threshold, vehicle speed matching brightness, steering wheel angle brightness, traffic flow brightness, and traffic flow light intensity threshold.

[0094] Among them, vehicle speed matching brightness is the influence of the current vehicle speed on the target brightness of the daytime running lights, steering wheel angle brightness is the influence of the current vehicle steering wheel angle on the target brightness of the daytime running lights, and traffic flow brightness is the influence of the current traffic flow on the target brightness of the daytime running lights.

[0095] When the vehicle is in a sunny condition, the determination of the target brightness of the daytime running lights provided in this application can be selected based on at least ambient light intensity, illuminance threshold, vehicle speed matching brightness, and steering wheel angle brightness. However, since a sunny condition actually includes both daytime and nighttime sunny conditions, this application provides an alternative embodiment for determining the target brightness of the daytime running lights when the vehicle is in a sunny condition: in a daytime sunny condition, the target brightness of the daytime running lights is determined based on daytime influence value, ambient light intensity, illuminance threshold, vehicle speed matching brightness, and steering wheel angle brightness; in a nighttime sunny condition, the target brightness of the daytime running lights is determined based on nighttime influence value, ambient light intensity, illuminance threshold, vehicle speed matching brightness, and steering wheel angle brightness. That is, the target brightness of the daytime running lights determined in a daytime sunny condition and a nighttime sunny condition may be different.

[0096] Specifically, assuming the vehicle is currently in a clear daytime condition between 18:00 and 08:00, corresponding to a clear nighttime condition, meaning the ambient light level is relatively low during this period, the target brightness of the daytime running lights (DRLs) can be calculated using the formula: L1 = K1 * (Q0 + β')V'. Here, L1 is the determined target brightness of the DRLs, K1 is the adjustment coefficient (i.e., the nighttime influence value), Q0 is the light intensity threshold, and β' is the steering wheel angle value β from the vehicle's current steering wheel angle information. The corresponding steering wheel angle brightness is preset for each vehicle model, with a mapping relationship (e.g., one-to-one mapping) between the corresponding steering wheel angle value β and the steering wheel angle brightness β'. This mapping relationship is used to realize the conversion of variables with different dimensions; V' is the speed-matched brightness corresponding to the current vehicle speed value V; in clear weather and at night, this application provides a method for determining the adjustment coefficient K1 as K1=(Q0-Q) / Q0, where Q is the ambient light intensity, which can be obtained in real time through the environmental detection module installed in the vehicle. That is, this application provides a method for determining the nighttime impact value by determining the nighttime impact value based on the difference between the light intensity threshold and the ambient light intensity, and the ratio to the light intensity threshold. Wherein, β=g*arcsin(W / D)*(180° / π); in addition, this application provides a method for calculating the speed-matched brightness V' as follows: V max The vehicle speed is preset with a maximum value; that is, the vehicle speed-matched brightness V' is based on the light intensity threshold Q0, the vehicle speed value V, and the preset maximum vehicle speed V. max It is confirmed; the above-mentioned values ​​are based on the light intensity threshold Q0, vehicle speed V, and the preset maximum vehicle speed V. max The formula for calculating the vehicle speed matching brightness V' is only one optional implementation method provided in this application, and this application is not limited to it. Where required, it can also be based on the light intensity threshold Q0, the vehicle speed value V, and the preset maximum vehicle speed V'. max Adjustments are made based on the calculation of the vehicle speed matching brightness V'.

[0097] It should be added that the maximum speed of a car varies depending on the model and configuration. Therefore, the preset maximum speed will differ for different types of vehicles. Furthermore, the preset maximum speed of the same vehicle with different configurations may also have slight differences. In other words, due to differences in the power performance of different cars, their maximum speed and / or preset maximum speed will not be the same.

[0098] The vehicle is currently in a sunny condition, between 8:00 AM and 6:00 PM, corresponding to a daytime sunny state. This means the ambient light intensity is relatively high during this time. To determine the target brightness of the daytime running lights (DRLs), the formula for calculating the target DRL brightness L2 is L2 = K2 * (Q + β')V', where L2 is the DRL brightness, K2 is the adjustment coefficient (i.e., the daytime influence value), and Q is the ambient light intensity. In a sunny, daytime condition, this application provides a method for determining the adjustment coefficient K2 as K2 = (Q - Q0) / Q, where Q0 is the illuminance threshold. That is, this application provides a method for determining the daytime influence value based on the difference between the ambient light intensity and the illuminance threshold, and the ratio of the difference to the ambient light intensity. The determination of steering wheel angle brightness β' can be achieved using the formula β = g * arcsin(W / D) * (180° / π) mentioned above, combined with the mapping relationship between the preset steering wheel angle value β and steering wheel angle brightness β'. The determination of speed-matched brightness V' can also be achieved using the aforementioned method. This formula is established.

[0099] It should be explained that the daytime and nighttime time boundaries provided in the above embodiments are 18:00 and 8:00, which are only one optional implementation method provided by this application. However, this application is not limited to this and the daytime and nighttime time boundaries can be adjusted according to actual needs, such as adjusting them according to the daily sunrise and sunset times, or adjusting them according to the season, etc. In addition, this application does not specifically limit the specific value of the light intensity threshold Q0, and its value can be set according to actual needs.

[0100] The above settings allow for different calculation methods when calculating the target brightness of the daytime running lights for different conditions, such as clear daytime and clear nighttime. This ensures that the target brightness of the daytime running lights can be better adapted to the needs of different time periods.

[0101] When the vehicle is in rainy weather, the determination of the target brightness of the daytime running lights provided in this application is based on ambient light intensity, illuminance threshold, vehicle speed matching brightness, steering wheel angle brightness, rainfall, and rainfall illuminance threshold; an alternative embodiment is provided here:

[0102] The vehicle is currently in rainy weather. To ensure that the daytime running lights (DRLs) provide appropriate illumination under different weather conditions, it is necessary to comprehensively consider the impact of rainfall and ambient light intensity on the brightness of the DRLs. Therefore, a formula for calculating the target brightness L3 of the DRLs is provided: L3=K1*(Q0+β')V'+K3*R'*V'; where K1 and K3 are adjustment coefficients, R is the rainfall amount, R' is the rainfall brightness corresponding to the rainfall amount R, and β=g*arcsin(W / D)*(180° / π); where K1=(Q0-Q) / Q0, K3=Q1 / Q0, Q1 represents the target light intensity level that needs to be achieved under rainfall conditions (i.e., the rainfall light intensity threshold), K3 changes with the rainfall amount, Q0 is the light intensity threshold, and Q is the ambient light intensity. Furthermore, the determination of steering wheel angle brightness β' can be achieved using the formula β=g*arcsin(W / D)*(180° / π) mentioned above, combined with the mapping relationship between the preset steering wheel angle value β and steering wheel angle brightness β'. The determination of speed-matched brightness V' can also be achieved using the aforementioned method. This formula is established.

[0103] When a vehicle is inside a tunnel, if there are few vehicles, the brightness of the daytime running lights (DRLs) can be reduced; if the traffic volume is high, the brightness of the DRLs needs to be increased. Therefore, a formula for calculating the target brightness L4 of the DRLs can be provided as L4 = K1 * (Q0 + β')V' + K4 * C' * V', where K1 and K4 are adjustment coefficients, C' is the brightness corresponding to the traffic volume C, and each vehicle type has a pre-set mapping relationship between the traffic volume C and the brightness C'. K1 = (Q0 - Q) / Q0, K4 = Q2 / Q0, and K4 changes with the traffic volume; C = C 总 / t, C 总 Let t represent the total number of vehicles in a given time period, and t represent time. Given the traffic flow C, the corresponding traffic flow brightness C' can be determined based on the mapping relationship between the current vehicle's pre-set traffic flow C and traffic flow brightness C'. Q2 represents the target illuminance level to be achieved under the base traffic flow, β = g * arcsin(W / D) * (180° / π), V is the target vehicle speed, Q0 is the illuminance threshold, and Q is the ambient light intensity. Furthermore, the determination of the steering wheel angle brightness β' can be achieved using the formula β = g * arcsin(W / D) * (180° / π) mentioned above, combined with the mapping relationship between the pre-set steering wheel angle value β and steering wheel angle brightness β'. The determination of the speed-matched brightness V' can be achieved using the aforementioned... This formula is established.

[0104] That is, such as Figure 2As shown, for the current vehicle, when the daytime running lights are illuminating based on the preset brightness of the current vehicle, that is, when the daytime running lights are on, the system will further detect the current environment of the vehicle. When it obtains data such as the current vehicle speed information, steering wheel angle information, and environmental conditions detected by the environmental detection unit, it will feed this data back to the daytime running light control unit. The daytime running light control unit will then control and adjust the target brightness of the daytime running lights according to different situations.

[0105] The specific adjustment methods include at least the four situations mentioned above. Specifically, firstly, when the vehicle is in a clear nighttime condition, the target brightness of the daytime running lights is calculated using L1=K1*(Q0+β')V', meaning the influence value of the target brightness of the daytime running lights includes at least the illuminance threshold Q0, steering wheel angle brightness β', and vehicle speed matching brightness V'; secondly, when the vehicle is in a clear daytime condition, the target brightness of the daytime running lights is calculated using L2=K2*(Q+β')V', meaning the influence value of the target brightness of the daytime running lights includes at least the ambient light intensity Q, steering wheel angle brightness β', and vehicle speed matching brightness V'; thirdly, in... When the vehicle is currently in rainy weather, the target brightness of the daytime running lights is calculated using L3=K1*(Q0+β')V'+K3*R'*V'. This means the target brightness of the daytime running lights is influenced by at least the light intensity threshold Q0, steering wheel angle brightness β', vehicle speed matching brightness V', and rainfall brightness R'. Fourthly, when the vehicle is currently inside a tunnel, the target brightness of the daytime running lights is calculated using L4=K1*(Q0+β')V'+K4*C'*V'. This means the target brightness of the daytime running lights is influenced by at least the light intensity threshold Q0, steering wheel angle brightness β', vehicle speed matching brightness V', and traffic flow brightness C'.

[0106] Furthermore, when the vehicle is in a clear night and inside a tunnel, the final target brightness L of the daytime running lights is determined as follows: L = max(L1, L4). Similarly, when the vehicle is in a rainy day and inside a tunnel, the final target brightness L of the daytime running lights is determined as follows: L = max(L3, L4).

[0107] Although this application only provides calculation methods for the target brightness of daytime running lights in four environments—clear daytime, clear nighttime, rainy day, and tunnel interior—it is not limited to these. When needed, the environmental information can be further refined to include: rural road environment, urban road environment, highway environment, parking lot environment, low temperature environment, high temperature environment, etc., and then different data information can be combined to determine the target brightness of the daytime running lights under different environments. For example, when calculating the target brightness of daytime running lights in low temperature and high temperature environments, the relevant calculation data may include temperature value, vehicle speed information, front wheel angle, front wheel wheelbase, vehicle turning radius, steering wheel and front wheel angle coefficient, ambient light intensity, illuminance threshold, vehicle speed matching brightness, and steering wheel angle brightness, etc. In addition, temperature thresholds may also be involved.

[0108] In addition, several alternative implementation methods are provided, including the following embodiments E1-E3:

[0109] In Example E1, when the vehicle is traveling in a clear night and inside a tunnel, the target brightness of the daytime running lights can be determined based on the maximum of L1 and L4.

[0110] In Example E2, when the vehicle is traveling in a sunny day and inside a tunnel, the target brightness of the daytime running lights can be determined based on the maximum of L2 and L4.

[0111] In Example E3, when the vehicle is traveling in rainy weather and inside a tunnel, the target brightness of the daytime running lights can be determined based on the maximum of L3 and L4.

[0112] Furthermore, when determining the target brightness of the daytime running lights based on whether the vehicle is traveling in sunny or rainy conditions, the traffic flow corresponding to the current vehicle can also be included. The corresponding calculation method is as follows: In clear night conditions: L'1 = K1 * (Q0 + β')V' + C f Under clear daylight conditions: L'2 = K2 * (Q + β')V' + C f In rainy weather: L'3 = K1 * (Q0 + β')V' + K3 * R' * V' + C f It needs to be explained that C f This application also defines the traffic flow brightness corresponding to traffic flow C. f The calculation method is not limited and can be selected according to needs, for example, C. f =C' or C f =K f *C' or C f =K f*C'*V', where C' is the traffic flow brightness corresponding to traffic flow C. This application pre-sets a mapping relationship between traffic flow C and traffic flow brightness C' for each vehicle type, K f This is an adjustment factor that can be set according to requirements.

[0113] In one exemplary embodiment, it further includes:

[0114] Based on the deflection value and deflection direction in the steering wheel angle information, the steering wheel angle value is determined, and the steering wheel angle brightness corresponding to the steering wheel angle value is determined based on a preset mapping table.

[0115] Specifically, as in the above embodiment, the calculation method for the target brightness of the daytime running lights, taking L1=K1*(Q0+β')V' as an example, β is the deflection value in the steering wheel angle information. For the steering wheel angle brightness β' corresponding to the deflection value β, this application provides an optional implementation method, taking the daytime running lights in the current vehicle as including a left daytime running light located on the left side of the vehicle body and a right daytime running light located on the right side of the vehicle body as an example, β can have different values ​​depending on the deflection direction of the current vehicle, thereby making the target brightness calculated by the left daytime running light and the right daytime running light different.

[0116] Specifically, the deflection value is positive when the deflection direction and the daytime running light (DRL) are in the same direction as the vehicle's body; and negative when they are in different directions. For example, if the vehicle is moving forward and the steering wheel is turned to the left, indicating a left turn, the β value in the target brightness adjustment data for the left DRL can be set to a positive value, while the β value for the right DRL can be set to a negative value. This results in a brighter left DRL than a brighter right DRL. Consequently, when the vehicle turns left, the left DRL will be more prominently visible to vehicles on its left, preventing collisions. Since the vehicle will move away from vehicles on its right when turning left, the right DRL only needs to achieve good visibility and does not need excessive brightness, thus avoiding energy waste.

[0117] Please refer to Figure 3 In one exemplary embodiment, in Figure 1 Before step 101 is executed, steps 105 and 106 may also be included, wherein:

[0118] Step 105: Obtain the current vehicle's power status, gear status, and power anti-theft authentication status.

[0119] The current power status of the vehicle may include the on / off status of the vehicle's overall power system, or the on / off status of any one or more devices within the vehicle. For example, it could refer to the on / off status of one or more power sources among various power devices such as the taillights, engine, headlights, and seat heaters. In other words, this application does not specifically limit which one or more power sources in the vehicle correspond to the power status in step 105; the specific content included in the power status can be adjusted according to actual needs.

[0120] The current gear status of a vehicle can include at least P gear and non-P gear. P gear can be called parking gear, parking gear, or parking gear. Non-P gear can include common gears such as R gear (reverse gear), N gear (neutral gear), D gear (drive gear), etc.

[0121] The current vehicle's power anti-theft authentication status includes successful and unsuccessful authentication. The power anti-theft authentication process is as follows: the BMS (Battery Management System) sends several frames of random numbers and authenticates the key based on the SK code and the random numbers. The BCM (Body Control Module) performs key authentication and sends several frames of key authentication status to the BMS. If the key authentication status received by the BMS from the BCM matches the BMS's, authentication is successful; otherwise, authentication fails. The anti-theft authentication result is then sent to the VCU (Vehicle Control Unit). The SK is the private key for the encryption algorithm, which is unique and can only be learned by the BMS and BCM on the same vehicle.

[0122] Optionally, step 105 can be used to obtain the current vehicle's power status, gear status, and power anti-theft authentication status. This data can be used to confirm whether the current vehicle's daytime running lights are in a ready state, so that the current vehicle can know whether the daytime running lights can be successfully turned on as needed.

[0123] Step 106: Determine the current status of the vehicle's daytime running lights based on the power status, gear status, and power anti-theft authentication status.

[0124] Specifically, step 106 can be executed to confirm whether the daytime running lights (DRLs) of the current vehicle are in a ready-to-be-activated state, based on the acquired power status, gear status, and power anti-theft authentication status. This determines whether the DRLs are in a ready-to-be-enabled state or a disabled state. If the DRLs are detected as enabled, further judgment can be made as needed to determine whether the DRLs need to be turned on, and the activation of the DRLs can be controlled based on the judgment result. If the DRLs are detected as disabled, the ready-to-be-enabled state of the DRLs needs to be monitored again, or further analysis needs to be conducted to determine why the DRLs are not enabled, until the DRLs are detected as enabled.

[0125] The vehicle daytime running light control method provided in this application controls whether the daytime running lights are turned on by the vehicle's power status, gear status, power anti-theft authentication status, and position light status. This helps reduce the vehicle's energy consumption. Furthermore, this method achieves automated control of whether the daytime running lights are turned on, which helps reduce the driver's workload and avoids the problem of forgetting to turn the daytime running lights on or off due to driver negligence. This improves driving safety and also helps to achieve energy conservation and emission reduction in motor vehicles.

[0126] It should be added that step 105 provided in this application determines whether the daytime running lights are enabled based on the current power status, gear status, and power anti-theft authentication status of the vehicle. However, this is only one optional implementation method provided by this application. Furthermore, this application can also provide an optional implementation method that determines whether the daytime running lights are enabled based on the current power status, motion status, and power anti-theft authentication status of the vehicle. Here, the current motion status of the vehicle refers to whether the vehicle is in motion or stationary, that is, whether the vehicle is displaced relative to the ground. This application does not limit what vehicle parameters are used to confirm the current motion status. For example, the current motion status of the vehicle can be confirmed based on the vehicle's position sensor, the engine status, the gear status, etc.

[0127] In one exemplary embodiment, such as Figure 3 As shown, step 106, which determines the current vehicle's daytime running light status based on power status, gear status, and power anti-theft authentication status, may include steps 201-203, wherein:

[0128] Step 201: With the power on, identify the gear position.

[0129] Step 202: When the gear position is in driving gear, identify the power anti-theft authentication status;

[0130] Step 203: If the power anti-theft authentication status is successful, determine that the daytime running lights of the current vehicle are enabled.

[0131] Specifically, when the current vehicle power status obtained in step 104 is, for example, the power status of the vehicle's power system, for the determination of the current vehicle's daytime running lights status based on power status, gear position, and power anti-theft authentication status performed in step 106, this application provides a judgment order for the above three factors as follows: after determining that the power status is on in step 201, the current vehicle's gear position is identified, and then step 202 is executed. If the gear position is determined to be in driving gear, the current vehicle's power anti-theft authentication status is further identified, and then step 203 is executed. If the power anti-theft authentication status is successful, the current vehicle's daytime running lights are determined to be enabled. However, this is only one optional judgment method provided by this application for whether the current vehicle's daytime running lights are enabled, and this application is not limited to this.

[0132] If the power status does not refer to the power status of the vehicle's power system, the execution process of step 106 may not follow the execution order of steps 201, 202, and 203.

[0133] In addition, as mentioned above, this application also provides a method for determining whether the daytime running lights are in an enabled state. That is, when the motion state indicates that the current vehicle is in a driving state, the power state is in an on state, and the power anti-theft authentication state is in an authenticated state, the daytime running lights of the current vehicle are considered to be in an enabled state. Of course, if the power state, gear state, or power anti-theft authentication state is different from any of the above states, then the daytime running lights of the current vehicle are in an disabled state.

[0134] Regarding the process of determining whether the daytime running lights are enabled, this application also provides an alternative embodiment, including... Figure 4 The process steps are as follows: First, obtain the vehicle's power status, gear position status, and vehicle power anti-theft status. Then, identify and judge the specific status of the vehicle's power status, gear position, and vehicle power anti-theft status. If the vehicle's power status is ON, the gear is not P, and the vehicle power anti-theft status is active, then the daytime running lights are enabled. Otherwise, the daytime running lights are disabled. The ON status indicates that the vehicle's power is on.

[0135] Regarding the control of whether daytime running lights are on or off, this application also provides an alternative embodiment, including... Figure 5The process steps shown are as follows: First, obtain the vehicle power status, vehicle gear status, vehicle power anti-theft status, and position light working status. Then, identify and judge the vehicle power status, vehicle gear status, vehicle power anti-theft status, and position light working status. If it is determined that the vehicle power status is ON, the vehicle gear is not P, the vehicle power anti-theft status is passed, and the position light working status is off, then the daytime running lights can be turned on. Otherwise, the daytime running lights are turned off.

[0136] Correspondingly, Figure 6 It also provides a procedure for controlling whether the daytime running lights are on or off. Specifically, it first obtains the enabling status of the daytime running lights and the working status of the position lights, and then identifies and judges the enabling status of the daytime running lights and the working status of the position lights. If it is determined that the enabling status of the daytime running lights is active and the position lights are off, then the daytime running lights are turned on; otherwise, the daytime running lights are turned off.

[0137] Regarding the control method for vehicle daytime running lights, this application also provides an optional implementation method as follows: First, acquire the vehicle's power status. Specifically, acquire the vehicle's power status through the vehicle's power system, including two states: ON and OFF; where ON represents on and OFF represents off. Second, acquire vehicle gear information. Specifically, acquire the vehicle's gear information through the vehicle gear control system, including two states: P and non-P; where P represents the vehicle being stationary and non-P represents the vehicle being in motion. Third, acquire vehicle power anti-theft authentication status. Specifically, acquire the vehicle power anti-theft authentication status through the vehicle power anti-theft authentication system, including two states: passed and failed. Then, based on the acquired vehicle power status, gear status, and power anti-theft status, determine whether the daytime running lights are enabled. If the power status is ON, the gear is non-P, and power authentication is passed, then the daytime running lights are considered enabled. Finally, acquire the operating status of the position lights. Specifically, acquire the operating status of the vehicle's position lights through the vehicle position light control system, including two states: on and off. The system determines whether a vehicle meets the conditions for activating its daytime running lights (DRLs) based on the enabling status of the DRLs and the operational status of the position lights. By using preset DRL activation conditions—that is, if the DRLs are enabled and the position lights are off—the system can activate the DRLs. Specifically, it assesses the vehicle's power status, gear position, vehicle power anti-theft authentication status, and position light operational status to determine if the vehicle meets the DRL activation conditions. Based on the assessment result, the system controls the activation and deactivation of the DRLs. If the vehicle meets the DRL activation conditions, the DRLs are activated; otherwise, they are deactivated. Through these technical means, the system can reduce vehicle energy consumption while maintaining vehicle visibility during driving. It also prevents drivers from forgetting to turn on the DRLs due to negligence, thus improving driving safety.

[0138] Based on the vehicle daytime running light control method provided in this application, intelligent control of the daytime running lights is achieved, resulting in energy conservation and emission reduction, and improving the user's driving experience. Specifically, the vehicle daytime running light control method provided in this application can automatically determine whether the vehicle meets the conditions for turning on the daytime running lights based on parameters such as the vehicle's power status, gear information, vehicle power anti-theft authentication status, and the working status of the position lights. It then automatically turns the daytime running lights on or off according to the determination result, achieving intelligent control, greatly reducing the driver's workload, and preventing the problem of forgetting to turn on the daytime running lights due to driver negligence, thus improving driving safety. Furthermore, it can reduce the energy consumption of the vehicle while ensuring its visibility during driving. Specifically, it intelligently controls the turning on and off of the daytime running lights according to the actual state of the vehicle, avoiding unnecessary energy waste and contributing to energy conservation and emission reduction. In addition, it can intelligently control the turning on and off of the daytime running lights according to the actual state of the vehicle, making the use of daytime running lights more flexible and convenient, optimizing the user experience, and improving user satisfaction with the vehicle.

[0139] It should be understood that although the steps in the flowcharts of the embodiments described above are shown sequentially according to the arrows, these steps are not necessarily executed in the order indicated by the arrows. Unless explicitly stated herein, there is no strict order restriction on the execution of these steps, and they can be executed in other orders. Moreover, at least some steps in the flowcharts of the embodiments described above may include multiple steps or multiple stages. These steps or stages are not necessarily completed at the same time, but can be executed at different times. The execution order of these steps or stages is not necessarily sequential, but can be performed alternately or in turn with other steps or at least some of the steps or stages of other steps.

[0140] Based on the same inventive concept, this application also provides a vehicle daytime running light control device for implementing the above-described vehicle daytime running light control method. The solution provided by this device is similar to the implementation described in the above method; therefore, the specific limitations of one or more vehicle daytime running light control device embodiments provided below can be found in the limitations of the vehicle daytime running light control method described above, and will not be repeated here.

[0141] In one exemplary embodiment, such as Figure 7 As shown, a control device 200 for vehicle daytime running lights is provided, including: a status recognition module 81, a control module 82, and a data acquisition module 83, wherein:

[0142] The status recognition module 81 is used to obtain the status of the daytime running lights and position lights of the current vehicle;

[0143] Control module 82 is used to turn on the daytime running lights based on the current vehicle's preset brightness when the daytime running lights and position lights are off;

[0144] Data acquisition module 83 is used to acquire environmental information, vehicle speed information and steering wheel angle information of the current vehicle.

[0145] The control module 82 is also used to determine the target brightness of the daytime running lights based on environmental information, vehicle speed information and steering wheel angle information, and adjust the brightness of the daytime running lights to the target brightness.

[0146] Specifically, the status recognition module 81 is used to acquire the status of the daytime running lights and the position lights of the current vehicle, so as to know that the daytime running lights need to be turned on when the position lights are detected to be in the off state, thereby improving the recognition of the current vehicle.

[0147] The control module 82 is used to turn on the daytime running lights by calling the current vehicle's preset brightness for the daytime running lights when it learns that both the daytime running lights and the position lights are off, so that the daytime running lights are in an illuminated state.

[0148] The data acquisition module 83 is used to acquire and identify the current situation of the vehicle, specifically including acquiring environmental information, vehicle speed information and steering wheel angle information of the current vehicle.

[0149] The control module 82, upon acquiring the current vehicle's environmental information, vehicle speed information, and steering wheel angle information, selects and acquires vehicle speed information and steering wheel angle information that can be combined to obtain the target brightness of the daytime running lights based on the environmental information. Then, based on the environmental information, and / or vehicle speed information, and / or steering wheel angle information, it calculates the target brightness of the daytime running lights for the current vehicle. Once the target brightness of the daytime running lights is determined, the brightness of the daytime running lights is adjusted to the target brightness. In other words, after the daytime running lights are turned on, this application further calculates the most suitable target brightness for the daytime running lights, enabling them to adjust to the most suitable target brightness as quickly as possible after being turned on, avoiding energy waste and thus improving vehicle safety while reducing energy consumption, thereby improving the vehicle's range. Furthermore, it also avoids insufficient initial brightness, ensuring that the daytime running lights enhance vehicle visibility.

[0150] In an exemplary embodiment, the control module 82 is configured to determine the target brightness of the daytime running lights (DRLs) based on at least ambient light intensity, illuminance threshold, vehicle speed matching brightness, and steering wheel angle brightness when the environmental information representation indicates a sunny day; to determine the target brightness of the DRLs based on at least ambient light intensity, illuminance threshold, vehicle speed matching brightness, steering wheel angle brightness, rainfall amount, and rainfall light intensity threshold when the environmental information representation indicates a rainy day; and to determine the target brightness of the DRLs based on at least ambient light intensity, illuminance threshold, vehicle speed matching brightness, steering wheel angle brightness, traffic flow brightness, and traffic flow light intensity threshold when the environmental information representation indicates a tunnel. The vehicle speed matching brightness is the influence of the current vehicle speed on the target brightness of the DRLs, the steering wheel angle brightness is the influence of the current vehicle steering wheel angle on the target brightness of the DRLs, and the traffic flow brightness is the influence of the current traffic flow level on the target brightness of the DRLs.

[0151] In an exemplary embodiment, the control module 82 is used to determine the vehicle speed matching brightness based on the vehicle speed value, the light intensity threshold, and the preset maximum value of the vehicle speed in the vehicle speed information.

[0152] In an exemplary embodiment, the control module 82 is used to determine the steering wheel angle value based on the deflection value and deflection direction in the steering wheel angle information, and to determine the steering wheel angle brightness corresponding to the steering wheel angle value based on a preset mapping table.

[0153] In one exemplary embodiment, the clear weather condition includes a daytime clear weather condition and a nighttime clear weather condition, and the target brightness of the daytime running lights is determined differently in the daytime clear weather condition and the nighttime clear weather condition.

[0154] In an exemplary embodiment, the data acquisition module 83 is used to determine the status of the daytime running lights of the current vehicle based on the acquired power status, gear status, and power anti-theft authentication status of the current vehicle.
