[0002] Daytime running lights, or DRLs for short, are mainly used as signal lights to alert the front of motor vehicles during the day.

[0053] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0054] The use of daytime running lights can effectively improve the recognition of motor vehicles during driving, thereby improving driving safety. However, the use of daytime running lights will also increase the energy consumption of motor vehicles. Therefore, how to reduce the energy consumption of motor vehicles while ensuring the recognition of motor vehicles during driving has become an important issue in current technological development.

[0055] The existing DRL control method is mainly implemented by manual operation of the driver. When the driver needs to turn on the DRL, he can do so by operating the corresponding switch. In addition, some advanced driver assistance systems (ADAS) can also automatically turn on the DRL according to the ambient light intensity.

[0056] However, there are some problems with the existing daytime running light control method. First, the existing daytime running light control method mainly relies on the manual operation of the driver, which increases the driver's operating burden to a certain extent. At the same time, the driver may forget to turn on the daytime running light due to negligence, thereby affecting driving safety. Second, the existing daytime running light control method cannot intelligently control the opening and closing of the daytime running light and the brightness of the daytime running light according to the actual state of the vehicle, which increases the energy consumption of the motor vehicle to a certain extent.

[0057] In an exemplary embodiment, Figure 1 As shown, a method for controlling a vehicle daytime running light is provided, which can be applied to a vehicle, a server corresponding to the vehicle, or a system including a vehicle and a corresponding server, and is implemented through the interaction between the vehicle and the server. This application takes the application of the method to a vehicle as an example, and includes the following steps 101 to 104. Among them:

[0058] Step 101, obtaining the status of the daytime running lights and position lights of the current vehicle.

[0059] Among them, the current vehicle can be a new energy vehicle or a traditional oil vehicle. The new energy vehicle can specifically be a pure electric vehicle or a hybrid electric vehicle. This application does not make specific limitations on this.

[0060] Specifically, the state of the daytime running lights of the current vehicle is acquired by executing step 101 to learn whether the daytime running lights are in the on state. If the daytime running lights are already in the on state, there is no need to execute the steps required to control the daytime running lights to turn on. In the case of learning that the daytime running lights are in the off state, it is further determined whether the daytime running lights are in the enabled state; if the daytime running lights are monitored to be in the enabled state, it is possible to further determine whether the daytime running lights need to be turned on according to the needs, so as to control the turning on of the daytime running lights based on the determination result; if the daytime running lights are monitored to be in the disabled state, it is necessary to monitor the preparation state of the daytime running lights again, or further analyze why the daytime running lights are not in the enabled state, until the daytime running lights are monitored to be in the enabled state.

[0061] Among them, the enabled state of the daytime running lights refers to the state in which the daytime running lights are ready and waiting to be turned on; the daytime running lights in the enabled state can further judge whether the daytime running lights need to be turned on according to needs, so as to control the turning on of the daytime running lights based on the judgment result.

[0062] When the daytime running lights are detected to be in the enabled state, it means that the daytime running lights are ready and can receive the command to turn on the daytime running lights at any time to turn on the daytime running lights. However, the present application also provides a judgment condition for turning on the daytime running lights, which is to further determine the state of the current vehicle position lights when the daytime running lights are in the enabled state.

[0063] The position lights of a car are lights that are used to show the location of the vehicle when they are turned on. When lit, they can show the outline of the vehicle. Their function is to indicate the size of the vehicle so that the vehicles in front and behind can distinguish the size and position of the vehicle in a dimly lit environment.

[0064] Therefore, the functions of the position lights and the daytime running lights are similar, and both can be used to improve the recognition of the vehicle; based on this, in the technical solution provided by the present application, the activation of the daytime running lights and the position lights is mutually exclusive, that is, when the position lights are in the on state, the daytime running lights cannot be turned on, and the daytime running lights can only be turned on when the position lights are in the off state; such a setting can not only ensure the improvement of the recognition of the vehicle during driving, but also reduce the energy consumed when the daytime running lights and the position lights are turned on at the same time, thereby reducing the energy consumption of the vehicle.

[0065] It should also be added that the present application does not specifically limit the order in which the daytime running light status and the position light status are acquired. The main purpose of executing step 101 is to know that the daytime running light is to be turned on when it is detected that the position light is in the off state.

[0066] Step 102: When the daytime running lights and the position lights are in an off state, the daytime running lights are turned on based on a preset brightness of the current vehicle.

[0067] Specifically, when executing step 101 to learn the status of the daytime running lights and the status of the position lights of the current vehicle, step 102 can be further executed. When it is determined that the daytime running lights and the position lights are both in the off state, it means that the daytime running lights of the vehicle can be further controlled to turn on. Therefore, the daytime running lights can be turned on based on the preset brightness of the current vehicle, so as to increase the recognition of the corresponding vehicle during driving based on the daytime running lights in the turned-on state, thereby improving driving safety.

[0068] Among them, the preset brightness of the daytime running lights of the current vehicle can be set at the factory, or it can be set by the user himself based on user needs. This application does not make specific restrictions on this; this application does not limit the specific brightness value of the preset brightness.

[0069] Step 103, obtaining the current vehicle environment information, vehicle speed information and steering wheel angle information.

[0070] Specifically, in order to make the brightness of the daytime running lights more suitable for the current situation of the vehicle, the present application provides an optional implementation method, after turning on the daytime running lights based on the preset brightness, further executing step 103 to obtain and identify the current situation of the vehicle, specifically including obtaining the current vehicle's environmental information, vehicle speed information and steering wheel angle information. The steering wheel angle information here may at least include the steering wheel's steering direction (deflection direction) and steering angle (deflection value).

[0071] By acquiring at least the current vehicle's environmental information, vehicle speed information, steering wheel angle information and other information, it is helpful to clarify the current situation of the vehicle, thereby facilitating the calculation of the target brightness of subsequent daytime running lights based on the vehicle's situation, so that the final target brightness of the daytime running lights is more suitable for the vehicle's situation, which helps to avoid the situation where the daytime running lights are too bright or too low.

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

[0073] Specifically, when the environmental information, vehicle speed information and steering wheel angle information of the current vehicle are obtained by executing 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, and then based on the environmental information, the target brightness of the daytime running lights of the current vehicle is calculated, and when the target brightness of the daytime running lights is determined, 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 turned-on state can be updated to the calculated target brightness; that is, after the daytime running lights are turned on, the application calculates the most suitable target brightness of 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 waste of vehicle energy, thereby helping to reduce the energy consumption of motor vehicles on the basis of improving vehicle safety, thereby helping to improve the endurance of the vehicle; in addition, it can also avoid the situation where the initial luminous brightness is insufficient to ensure the improvement of the vehicle recognition of the daytime running lights.

[0074] It should be noted that, in view of the different environments in which the current vehicle is located, when calculating the target brightness of the daytime running lights of the current vehicle, the required data may include only one of the three information, such as only the environmental information, the vehicle speed information and the steering wheel angle information; it is also possible that based on the different environments, any two or all of the three information, such as the environmental information, the vehicle speed information and the steering wheel angle information, are required, and the present application does not limit this; for example, the target brightness of the daytime running lights can be determined based on the environmental information, the vehicle speed information and the steering wheel angle information, which is also conducive to further improving the accuracy of the determined target brightness of the daytime running lights. In addition, in the case where the current vehicle is in a complex environment, it is also possible to determine the target brightness of the daytime running lights of the current vehicle based on the environmental information, the vehicle speed information and the steering wheel angle information, in combination with other data, so that the vehicle can have a more appropriate target brightness. Among them, other data, such as traffic flow data.

[0075] The control method of the daytime running lights of a vehicle provided by the present application obtains the status of the daytime running lights and the position lights of the current vehicle; when the position lights are in the off state, turns on the daytime running lights based on the preset brightness of the current vehicle; obtains the environmental information, vehicle speed information and steering wheel angle information of the current vehicle; determines the target brightness of the daytime running lights based on the environmental information, vehicle speed information and steering wheel angle information, and adjusts the luminous brightness of the daytime running lights to the target brightness; by turning on the daytime running lights based on the preset brightness of the current vehicle after determining that the position lights are in the off state, the speed of turning on the daytime running lights can be increased, so as to quickly improve the recognition of the vehicle by turning on the daytime running lights, and then adjusts the brightness of the daytime running lights to be more adapted to the environment, that is, adjusts the luminous brightness of the daytime running lights to the target brightness, thereby helping to reduce the energy consumption problem of the vehicle, and realizing automatic control of whether the daytime running lights are turned on by the method, which helps to reduce the operating burden of the vehicle driver, thereby helping to avoid the problem of forgetting to turn on or off the daytime running lights due to the negligence of the driver, improving driving safety, and also helping to achieve energy conservation and emission reduction of motor vehicles.

[0076] It should be added that, for the determination of the steering wheel angle information, the present application provides an optional implementation method, which is to obtain the data such as the front wheel angle, front wheel wheelbase, body turning radius and steering wheel and front wheel angle coefficient of the current vehicle, and then determine the steering wheel angle information of the current vehicle based on the obtained front wheel angle, front wheel wheelbase, body turning radius and steering wheel and front wheel angle coefficient. Of course, this is only one method for determining the steering wheel angle information provided by the present application, but the present application is not limited to this.

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

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

[0079] It should also be added that a value range can be preset 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, the present application provides an optional 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 added that, when calculating the target brightness of the daytime running lights, if the calculation of the target brightness of the daytime running lights involves the turning radius of the vehicle body, the target turning radius used in the calculation of the target brightness of the daytime running lights is not necessarily the real-time turning radius of the current vehicle body; the present application provides a method for determining the target turning radius used in the calculation of the target brightness of the daytime running lights: first determine the real-time speed of the current vehicle, and then determine the target turning radius required to calculate the target brightness of the daytime running lights based on the real-time speed. In this regard, the present application provides an optional implementation method: when the real-time vehicle speed is greater than or equal to 50Km / h, the target turning radius takes the maximum value in the corresponding value range, for example, the target turning radius takes 30 meters, so that the corresponding calculated target brightness of the daytime running lights can have a higher brightness, thereby allowing the vehicles around the current vehicle to more clearly identify the current vehicle, so as to avoid the problem of collision between vehicles caused by excessive speed, which is beneficial to improving vehicle driving safety; correspondingly, when the real-time vehicle speed is less than 50Km / h, the target turning radius can be taken as the actual vehicle body turning radius, so that the corresponding calculated target brightness of the daytime running lights can be a more appropriate brightness, avoiding the situation where the brightness is too dark or too high, which can not only ensure the improvement of the recognition of the current vehicle by the target brightness of the daytime running lights, but also avoid the waste of vehicle energy when the daytime running lights are turned on.

[0081] It should be noted that the above-mentioned control of the target turning radius used in calculating the target brightness of the daytime running lights with the vehicle speed of 50Km / h as the node is only an optional implementation method provided by the present application, but the present application is not limited to this; the speed node value can be adjusted according to actual needs. In addition to the 50Km / h provided in the present application, for example, the speed node value can also be selected as 60Km / h, 65Km / h, 45Km / h, etc.

[0082] Based on this, for the above content "determine the steering wheel angle information of the current vehicle based on the front wheel angle, front wheel wheelbase, vehicle body turning radius, and steering wheel and front wheel angle coefficient", the present application provides a calculation formula for 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); wherein, g is the steering wheel and front wheel angle coefficient mentioned above in the present application, φ is the front wheel angle mentioned above in the present application, W is the front wheel wheelbase mentioned above in the present application, and D is the vehicle body turning radius mentioned above in the present application.

[0083] It should also be added that the front wheel wheelbase W and the steering wheel and front wheel angle coefficient g are set at the factory, that is, for the same model, the front wheel wheelbase W and the steering wheel and front wheel angle coefficient g are the same. It should be noted that the calculation formula for the angle value β in the steering wheel angle information of the current vehicle provided in this application can be applied to any model of vehicle, as long as the vehicle of the corresponding model can provide the steering wheel and front wheel angle coefficient g, the front wheel angle φ, the front wheel wheelbase W and the body turning radius D.

[0084] In addition, it should be added that the content of step 103 provided above in the present application is to first calculate the target brightness of the daytime running lights, and then adjust the luminous brightness of the daytime running lights based on the calculated target brightness, so that the daytime running lights can be adjusted to a more appropriate target brightness based on the preset brightness. However, this is only an optional implementation method provided by the present application. It is also possible to first obtain the current vehicle's environmental information, vehicle speed information and steering wheel angle information when it is known that the position lights are in the off state, determine the target brightness of the daytime running lights based on the environmental information, vehicle speed information and steering wheel angle information, and then turn on the daytime running lights based on the target brightness. In this way, when the daytime running lights are turned on, they can be turned on with the optimal luminous brightness.

[0085] It should also be added that when the daytime running lights are illuminated 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 at a most appropriate brightness in real time; in addition, the update of the target brightness when the daytime running lights are in the on state can also be updated based on a preset time period, and the present application does not make any specific limitations on this.

[0086] In an exemplary embodiment, the method for controlling a vehicle daytime running light provided by the present application further includes:

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

[0088] Specifically, with respect to the technical content of determining the target brightness of the daytime running lights based on environmental information, vehicle speed information and steering wheel angle information provided above, the present application also provides an optional implementation method of first determining a set of influencing factors of the brightness of the daytime running lights based on environmental information. The 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 days, rainy days and tunnels.

[0089] An exemplary explanation is provided. Compared with sunny days and rainy days, the influencing factors of the target brightness of the daytime running lights on rainy days may also be related to the amount of rainfall. Then, based on the determined set of influencing factors and at least one of the vehicle speed information and the steering wheel angle information, the target brightness of the daytime running lights that best suits the current vehicle is calculated to improve the adaptability of the calculated target brightness of the daytime running lights to the vehicle's environment and state (including the target vehicle speed and steering wheel angle information), thereby further reducing the energy consumption of the vehicle when the daytime running lights are turned on, and at the same time ensuring the recognizability of the motor vehicle during driving.

[0090] In an exemplary embodiment, based on this, for determining the target brightness of the daytime running light, the present application also provides some optional implementations, including:

[0091] When the environmental information indicates that the weather is sunny, determining the target brightness of the daytime running lights 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 indicates that it is raining, determining the target brightness of the daytime running lights based on at least the ambient light intensity, the light intensity threshold, the vehicle speed matching brightness, the steering wheel angle brightness, the rainfall amount and the rainfall light intensity threshold;

[0093] When the environmental information indicates that the vehicle is inside a tunnel, the target brightness of the daytime running lights is determined based on at least the ambient light intensity, the light intensity threshold, the vehicle speed matching brightness, the steering wheel angle brightness, the traffic volume brightness, and the traffic volume light intensity threshold;

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

[0095] When the vehicle is in a sunny day state, the determination of the target brightness of the daytime running lights provided in the present application can be selectively implemented based on at least the ambient light intensity, the light intensity threshold, the vehicle speed matching brightness and the steering wheel angle brightness; however, since the sunny day state actually includes the daytime sunny day state and the nighttime sunny day state, therefore, for the determination of the target brightness of the daytime running lights when the vehicle is in a sunny day state, the present application provides an optional embodiment: in the daytime sunny day state, the target brightness of the daytime running lights is determined based on the daytime impact value, the ambient light intensity, the light intensity threshold, the vehicle speed matching brightness and the steering wheel angle brightness; in the nighttime sunny day state, the target brightness of the daytime running lights is determined based on the nighttime impact value, the ambient light intensity, the light intensity threshold, the vehicle speed matching brightness and the steering wheel angle brightness; that is, the target brightness of the daytime running lights determined in the daytime sunny day state and the nighttime sunny day state may be different.

[0096] Specifically, the current vehicle is in a sunny day, and the time is between 18:00 and 08:00, which corresponds to a night sunny state, that is, the ambient light brightness during this time period is relatively dim. At this time, if the target brightness of the daytime running lights is to be determined, the calculation formula for the corresponding daytime running lights target brightness L1 can be L1=K1*(Q0+β')V', where L1 is the determined target brightness of the daytime running lights, K1 is the adjustment coefficient, that is, the night impact value, Q0 is the light intensity threshold, and β' is the steering angle value β in the steering wheel angle information of the current vehicle. Corresponding steering wheel angle brightness, each vehicle model is pre-set with a mapping relationship between the corresponding steering wheel angle value β and the steering wheel angle brightness β' (for example, a one-to-one mapping), and the mapping relationship is used to realize the conversion of variables of different dimensions; V' is the speed matching brightness corresponding to the current vehicle speed value V; in a sunny state, and at night time, the present application provides a method for determining the adjustment coefficient K1, K1= (Q0-Q) / Q0, where Q is the ambient light intensity, which can be obtained in real time through the environment detection module installed in the vehicle. That is, the present application provides a method for determining the night impact value, which is to determine the night 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, the present application provides a method for calculating the speed matching brightness V' as follows: , where V max The vehicle speed preset maximum value, that is, the vehicle speed matching brightness V' is based on the light intensity threshold Q0, the vehicle speed value V and the vehicle speed preset maximum value V max Determined; the above-provided light intensity threshold Q0, vehicle speed value V and vehicle speed preset maximum value V max The formula for calculating the vehicle speed matching brightness V' is only an optional implementation provided by the present application, and the present application is not limited thereto. If required, the formula can also be based on the light intensity threshold Q0, the vehicle speed value V and the vehicle speed preset maximum value V max Calculate the vehicle speed and adjust the brightness V'.

[0097] It should be added that the maximum speed of a car varies with different models and configurations. Therefore, for different types of vehicles, the corresponding maximum speed preset values ​​may also be different. Furthermore, the maximum speed preset values ​​corresponding to the same vehicle with different configurations may also be slightly different. That is, due to the differences in the power performance of different cars, their maximum speeds and / or maximum speed preset values ​​may be different.

[0098] The current vehicle is in a sunny day, and the time is between 8:00 and 18:00, which corresponds to a sunny day state, that is, the ambient light brightness during this time period is relatively bright. At this time, if the target brightness of the daytime running lights is to be determined, the corresponding calculation formula for the target brightness of the daytime running lights L2 can be L2=K2*(Q+β')V', where L2 is the brightness of the daytime running lights, K2 is the adjustment coefficient, that is, the daytime impact value, and Q is the ambient light intensity; in a sunny day state and during daytime, the present application provides a method for determining the adjustment coefficient K2, K2=(Q-Q0) / Q, where Q0 is the light intensity threshold. That is, the present application provides a method for determining the daytime impact value, which is to determine the daytime impact value based on the difference between the ambient light intensity and the light intensity threshold, and the ratio to the ambient light intensity. Regarding the determination of the steering wheel angle brightness β', the above formula β=g*arcsin(W / D)*(180° / π) can be used, and combined with the mapping relationship between the preset steering wheel angle value β and the steering wheel angle brightness β', the vehicle speed matching brightness V' can be determined by the above formula This formula is determined.

[0099] It should be explained that the time limits of day and night provided in the above embodiment are 18:00 and 8:00, which is only an optional implementation provided by the present application, but the present application is not limited thereto, and the time limits of day and night can be adjusted according to actual needs, for example, according to the daily sunrise and sunset time, or according to the season, etc. In addition, the present 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] Through the above settings, when calculating the target brightness of the daytime running lights of the current vehicle, different calculation methods are used in the daytime sunny state and the night sunny state, so that in different time periods, the target brightness of the daytime running lights can be more adapted to the needs of the time period.

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

[0102] The vehicle is currently in rainy weather. In order for the daytime running lights to provide appropriate lighting under different weather conditions, it is necessary to comprehensively consider the effects of rainfall and ambient light intensity on the brightness of the daytime running lights. Therefore, a calculation formula for the target brightness L3 of the daytime running lights is provided, which can be L3=K1*(Q0+β')V'+K3*R'*V'; wherein, K1 and K3 are adjustment coefficients, R is the rainfall, R' is the rainfall brightness corresponding to the rainfall R, β=g*arcsin(W / D)*(180° / π); wherein, K1=(Q0-Q) / Q0, K3=Q1 / Q0, Q1 represents the target light intensity level that needs to be achieved in rainfall conditions (that is, the rainfall light intensity threshold), K3 changes with the change of rainfall, Q0 is the light intensity threshold, and Q is the ambient light intensity. In addition, the steering wheel angle brightness β' can be determined by using the above formula β=g*arcsin(W / D)*(180° / π), and combined with the mapping relationship between the preset steering wheel angle value β and the steering wheel angle brightness β', the vehicle speed matching brightness V' can be determined by using the above formula This formula is determined.

[0103] When the vehicle is inside a tunnel, if there are fewer vehicles in the tunnel, the brightness of the daytime running lights can be reduced. If the traffic volume is large, the brightness of the daytime running lights needs to be increased. Therefore, a calculation formula for the target brightness L4 of the daytime running lights is provided, which can be L4=K1*(Q0+β')V'+K4*C'*V', wherein K1 and K4 are adjustment coefficients, C' is the traffic volume brightness corresponding to the traffic volume C, and each vehicle model is preset with a corresponding mapping relationship between the traffic volume C and the traffic volume brightness C', K1=(Q0-Q) / Q0, K4=Q2 / Q0, and K4 changes with the change of traffic volume; C=C 总 / t,C 总 Represents the total number of vehicles in a certain period of time, t represents time. When the traffic volume C is obtained, the corresponding traffic volume brightness C' can be determined based on the mapping relationship between the preset traffic volume C and the traffic volume brightness C' of the current vehicle; Q2 represents the target light intensity level to be achieved under the basic traffic volume, β=g*arcsin(W / D)*(180° / π), V is the target vehicle speed, Q0 is the light intensity threshold, and Q is the ambient light intensity. In addition, regarding the determination of the steering wheel angle brightness β', the above-mentioned formula β=g*arcsin(W / D)*(180° / π) can be used, and combined with the mapping relationship between the preset steering wheel angle value β and the steering wheel angle brightness β', the method for determining the vehicle speed matching brightness V' can be determined using the above-mentioned This formula is determined.

[0104] That is, if Figure 2As shown, for the current vehicle, when the daytime running lights are illuminated based on the preset brightness of the current vehicle, that is, when the daytime running lights are turned on, the situation of the current vehicle will be further detected, and when the speed information and steering wheel angle information of the current vehicle, as well as the environmental conditions detected by the environmental detection unit are obtained, these data will be fed back to the daytime running light control unit, and the daytime running light control unit will control and adjust the target brightness of the daytime running lights according to different situations.

[0105] The specific adjustment method includes at least the four situations as described above, that is, first, when the current vehicle is in a clear night state, L1=K1*(Q0+β')V' is used to calculate the target brightness of the daytime running lights, that is, the influencing value of the target brightness of the daytime running lights at least includes the light intensity threshold Q0, the steering wheel angle brightness β', and the vehicle speed matching brightness V'; second, when the current vehicle is in a clear day state, L2=K2*(Q+β')V' is used to calculate the target brightness of the daytime running lights, that is, the influencing value of the target brightness of the daytime running lights at least includes the ambient light intensity Q, the steering wheel angle brightness β', and the vehicle speed matching brightness V'; third, when the current vehicle is in a clear day state, L2=K2*(Q+β')V' is used to calculate the target brightness of the daytime running lights, that is, the influencing value of the target brightness of the daytime running lights at least includes the ambient light intensity Q, the steering wheel angle brightness β', and the vehicle speed matching brightness V'; When the vehicle is currently in the rain, L3=K1*(Q0+β')V'+K3*R'*V' is used to calculate the target brightness of the daytime running lights, that is, the influencing values ​​of the target brightness of the daytime running lights at least include the light intensity threshold Q0, the steering wheel angle brightness β', the vehicle speed matching brightness V', and the rainfall brightness R'; fourthly, when the vehicle is currently in the tunnel, L4=K1*(Q0+β')V'+K4*C'*V' is used to calculate the target brightness of the daytime running lights, that is, the influencing values ​​of the target brightness of the daytime running lights at least include the light intensity threshold Q0, the steering wheel angle brightness β', the vehicle speed matching brightness V', and the traffic volume brightness C'.

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

[0107] Although the above-mentioned application only provides a method for calculating the target brightness of daytime running lights under four environments: sunny day, sunny night, rainy day and inside a tunnel, the present application is not limited to this. If needed, for example, 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 the target brightness of the daytime running lights can be determined by combining different data information in different environments; for example, when calculating the target brightness of daytime running lights under low temperature environment and high temperature environment, the relevant calculation data may include temperature value, vehicle speed information, front wheel angle, front wheel wheelbase, vehicle body turning radius, steering wheel and front wheel angle coefficient, ambient light intensity, light intensity threshold, vehicle speed matching brightness and steering wheel angle brightness, etc. In addition, for example, temperature threshold may also be involved.

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

[0109] Embodiment E1: when the vehicle is currently traveling in a clear night and in a tunnel, the target brightness of the daytime running light may be determined based on the maximum of L1 and L4;

[0110] Embodiment E2: When the vehicle is currently traveling in a sunny day and in a tunnel, the target brightness of the daytime running light may be determined based on the maximum of L2 and L4.

[0111] Embodiment E3: when the vehicle is currently traveling in the rain and in a tunnel, the target brightness of the daytime running lights may be determined based on the maximum of L3 and L4.

[0112] In addition, when the vehicle is traveling in sunny or rainy weather, the traffic volume corresponding to the current vehicle can also be added to the determination factor of the target brightness of the daytime running lights. The corresponding optional calculation method provided here is: In the case of a clear night: L'1=K1*(Q0+β')V'+C f , under sunny conditions: L'2=K2*(Q+β')V'+C f , in rainy days: L'3=K1*(Q0+β')V'+K3*R'*V'+C f , it needs to be explained that C f It is also the traffic flow brightness corresponding to the traffic flow C. In this application, the traffic flow brightness C f There is no limitation on the calculation method, which can be selected according to the 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 the traffic flow C. This application presets a mapping relationship between the corresponding traffic flow C and the traffic flow brightness C' for each vehicle model. K f It is the adjustment coefficient and can be set according to needs.

[0113] In an exemplary embodiment, it also includes:

[0114] Based on the deflection value and the 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 the calculation method of the target brightness of the daytime running lights provided in the above embodiment, taking L1=K1*(Q0+β')V' as an example, β is the deflection value in the steering wheel angle information, and for the steering wheel angle brightness β' corresponding to the deflection value β, the present application provides an optional implementation method, taking the daytime running lights in the current vehicle including a left daytime running light arranged on the left side of the vehicle body, and a right daytime running light arranged on the right side of the vehicle body as an example, β can have different values ​​according to the different deflection directions of the current vehicle, thereby making the target brightnesses finally calculated for the left daytime running light and the right daytime running light different.

[0116] Among them, when the deflection direction and the setting direction of the daytime running light on the current vehicle body are the same, the deflection value is a positive value, and when the deflection direction and the setting direction of the daytime running light on the current vehicle body are different, the deflection value is a negative value. For example, when the current vehicle is moving forward, if the deflection direction of the steering wheel is left, then the vehicle is about to turn left. At this time, the β in the target brightness adjustment data corresponding to the left daytime running light can be set to a positive value, and the β in the target brightness adjustment data corresponding to the right daytime running light can be set to a negative value. Then the brightness of the left daytime running light obtained by the final adjustment will be greater than the brightness of the right daytime running light. That is, when the vehicle turns left, the left daytime running light of the current vehicle can more prominently remind the vehicle on the left side of the current vehicle to avoid the current vehicle from scratching other vehicles on the left side of the vehicle body when turning left. When the vehicle turns left, it will move away from the vehicle on its right side. As long as the right daytime running light can achieve a good recognition effect, it does not need to have too high brightness, which is conducive to avoiding waste of vehicle energy.

[0117] Please refer to Figure 3 In an exemplary embodiment, Figure 1 Before the step 101 is performed, the steps 105 and 106 may be included, wherein:

[0118] Step 105, obtaining the current power status, gear status and power anti-theft authentication status of the vehicle.

[0119] The power state of the current vehicle may include the on or off state of the vehicle power system of the current vehicle, and may also include the on or off state of the power corresponding to any device or any several devices in the current vehicle, such as the on or off state of one or more corresponding power supplies of the current vehicle's taillight power supply, engine power supply, headlight power supply, seat heating power supply, etc. That is, the present application does not specifically limit which power supply or several power supplies in the vehicle correspond to the power state in step 105, and the specific content included in the power state can be adjusted according to actual needs.

[0120] The current gear status of the vehicle may include at least P gear and non-P gear, where P gear may be called parking gear, or parking gear, or parking gear; the above-mentioned non-P gear may include, for example, the common R gear (reverse gear), N gear (neutral gear), D gear (forward gear), etc.

[0121] The current vehicle's power anti-theft authentication status includes authentication passed and authentication failed; the power anti-theft authentication process is, for example, BMS (Battery Management System) will send several frames of random numbers, and authenticate the key based on the SK code and random numbers, BCM (Body Control Module) performs key authentication and sends several frames of key authentication status to BMS, and then BMS receives the key authentication status sent by BCM and BMS is equal, the authentication is passed, otherwise the authentication is failed, and then the anti-theft authentication result is sent to VCU (Vehicle Control Unit). Among them, SK is the private key of the encryption algorithm, which is unique, and only BMS and BCM on the same vehicle can learn accordingly.

[0122] Optionally, the power status, gear status and power anti-theft authentication status of the current vehicle are first obtained by executing step 105. These data can be used to confirm whether the daytime running lights of the current vehicle are in a standby state, so that the current vehicle can know whether the daytime running lights can be successfully turned on as needed later.

[0123] Step 106, determining the state of the daytime running lights of the current vehicle based on the power state, the gear state and the power anti-theft authentication state.

[0124] Specifically, step 106 can be performed to confirm whether the daytime running lights of the current vehicle are in a state of being ready to be activated based on the acquired power state, gear state and power anti-theft authentication state, so as to determine whether the daytime running lights are in a ready enabled state or in a non-ready disabled state. If the daytime running lights are detected to be in an enabled state, it can be further determined whether the daytime running lights need to be turned on according to the needs, so as to control the turning on of the daytime running lights based on the determination result; if the daytime running lights are detected to be in a non-enabled state, it is necessary to monitor the ready state of the daytime running lights again, or further analyze why the daytime running lights are not in an enabled state, until the daytime running lights are detected to be in an enabled state.

[0125] In the vehicle daytime running light control method provided by the present application, whether the vehicle daytime running lights are turned on is controlled by the vehicle's power status, gear status, power anti-theft authentication status and position light status, which is beneficial to reducing the vehicle's energy consumption problem. The method also realizes automatic control of whether the vehicle's daytime running lights are turned on, which is beneficial to reducing the vehicle driver's operating burden, thereby helping to avoid the problem of the driver forgetting to turn on or off the daytime running lights due to negligence, thereby improving driving safety and helping to achieve energy conservation and emission reduction of motor vehicles.

[0126] It should be added that in step 105 provided above in the present application, whether the daytime running lights are in an enabled state is determined based on the power state, gear state and power anti-theft authentication state of the current vehicle, but this is only an optional implementation provided by the present application; in addition, the present application can also provide an optional implementation for determining whether the daytime running lights are in an enabled state based on the power state, motion state and power anti-theft authentication state of the current vehicle. Among them: the motion state of the current vehicle refers to whether the current vehicle is in a driving state or a stationary state, that is, whether the current vehicle is displaced relative to the ground. The present application does not limit the parameters of the vehicle based on which the motion state of the current vehicle is confirmed. For example, the motion state of the current vehicle can be confirmed based on the vehicle's position sensor, or can be confirmed based on the state of the engine, or can be confirmed based on the gear state of the vehicle, and so on.

[0127] In an exemplary embodiment, Figure 3 As shown, the step 106 performed to determine the state of the daytime running lights of the current vehicle based on the power state, the gear state and the power anti-theft authentication state may include steps 201 to 203, wherein:

[0128] Step 201, when the power state is in the on state, identifying the gear state;

[0129] Step 202, when the gear state is in the driving gear state, identifying the power anti-theft authentication state;

[0130] Step 203: when the power anti-theft authentication state is in the state of authentication passed, determine that the daytime running lights of the current vehicle are in the enabled state.

[0131] Specifically, in the case where the power state of the current vehicle obtained in step 104 is, for example, the power state of the vehicle power system, for the determination of the state of the daytime running lights of the current vehicle based on the power state, gear state and power anti-theft authentication state performed in step 106, the present application provides a judgment order for the above three factors, which is to identify the gear state of the current vehicle when the power state is determined to be in the on state in step 201, and then execute step 202. When it is determined that the gear state is in the driving gear, the power anti-theft authentication state of the current vehicle is further identified, and then step 203 is executed to determine that the daytime running lights of the current vehicle are in the enabled state when the power anti-theft authentication state is in the authenticated state. However, this is only an optional judgment method for whether the daytime running lights of the current vehicle are in the enabled state provided by the present application, and the present application is not limited to this.

[0132] When the power state does not refer to the power state of the vehicle power system, the execution process of step 106 may not follow the execution order of step 201 , step 202 , and step 203 .

[0133] In addition, as mentioned above, the present application also provides a method for judging 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, and the power state is in an on state, and the power anti-theft authentication state is in an authenticated state, it is considered that the daytime running lights of the current vehicle are in an enabled state. Of course, as long as the power state, gear state and power anti-theft authentication state are different from any of the above states, the daytime running lights of the current vehicle are in a disabled state.

[0134] Regarding the process of determining whether the daytime running lights are in an enabled state, the present application also provides an optional embodiment, including: Figure 4 The process steps shown are specifically as follows: first obtain the vehicle power status, vehicle gear status and vehicle power anti-theft status, and then identify and judge the specific status of the vehicle power status, vehicle gear status and vehicle power anti-theft status. If it is judged that the vehicle power status is ON gear, the vehicle gear is not P gear, and the vehicle power anti-theft status passes, it means that the daytime running lights are in an enabled state, otherwise it means that the daytime running lights are in a disabled state. Among them, the vehicle power status ON gear means that the vehicle power status is in the open gear.

[0135] In order to control whether the daytime running lights are turned on or off, the present application also provides an optional embodiment, including Figure 5The process steps shown are specifically as follows: first obtain the vehicle power status, vehicle gear status, vehicle power anti-theft status and position light working status, and then identify and judge the vehicle power status, vehicle gear status, vehicle power anti-theft status and position light working status. If it is judged that the vehicle power status is ON gear, the vehicle gear is not P gear, the vehicle power anti-theft status is passed, and the position light working status is off, the daytime running lights can be turned on, otherwise the daytime running lights are turned off.

[0136] Correspondingly, Figure 6 A corresponding step process for controlling whether the daytime running lights are turned on or off is also provided, specifically: first obtain the daytime running light enable status and the position light working status, and then identify and judge the daytime running light enable status and the position light working status. If it is determined that the daytime running light enable status is activated and the position light is turned off, turn on the daytime running lights, otherwise turn off the daytime running lights.

[0137] For the control method of the vehicle daytime running light, the present application also provides an optional implementation method: obtaining the power state of the whole vehicle, specifically, obtaining the power state of the motor vehicle through the whole vehicle power system, including two states of ON gear and OFF gear; wherein ON gear represents opening, and OFF gear represents closing. Obtaining the gear information of the vehicle, specifically, obtaining the gear information of the motor vehicle through the vehicle gear control system, including two states of P gear and non-P gear; wherein P gear represents that the vehicle is stationary, and non-P gear represents that the vehicle is driving. Obtaining the vehicle power anti-theft authentication status, specifically, obtaining the power anti-theft authentication status of the motor vehicle through the vehicle power anti-theft authentication system, including two states of passing and failing. Then, through the obtained whole vehicle power state, gear state and power anti-theft state, it can be determined whether the daytime running light is in the enabled state. If the power state is in the ON gear, the gear is not in the P gear, and the power authentication passes at the same time, the daytime running light is considered to be in the enabled state. Then, obtaining the working state of the position light, specifically, obtaining the working state of the position light of the motor vehicle through the vehicle position light control system, including two states of opening and closing. Determine whether the motor vehicle meets the daytime running light turn-on conditions based on the daytime running light enable status and the working status of the position light. Through the preset daytime running light turn-on conditions, that is, when the daytime running lights are enabled, if the position lights are in the off state, the daytime running lights can be turned on. That is, the obtained vehicle power status, vehicle gear information, vehicle power anti-theft authentication status, and the working status of the position lights are judged to determine whether the motor vehicle meets the daytime running light turn-on conditions; control the turning on and off of the daytime running lights based on the judgment results; if the motor vehicle meets the daytime running light turn-on conditions, turn on the daytime running lights; if the daytime running light turn-on conditions are not met, turn off the daytime running lights. Through the above technical means, the purpose of reducing the energy consumption of motor vehicles can be achieved on the basis of ensuring the recognition of motor vehicles during driving; at the same time, it can also avoid the problem of forgetting to turn on the daytime running lights due to driver negligence, thereby improving driving safety.

[0138] Based on the above-mentioned vehicle daytime running light control method provided by the present application, the intelligent control of the daytime running light is realized, the effect of energy saving and emission reduction is achieved, and it is conducive to improving the user's car experience; specifically, the vehicle daytime running light control method provided by the present application can automatically determine whether the motor vehicle meets the daytime running light opening conditions according to parameters such as the vehicle power state, vehicle gear information, vehicle power anti-theft authentication status, and the working status of the position light, and automatically turn on or off the daytime running light according to the judgment result, realizing intelligent control, greatly reducing the driver's operating burden, and at the same time avoiding the problem of forgetting to turn on the daytime running light due to driver negligence, thereby improving driving safety. In addition, it can achieve the purpose of reducing the energy consumption of the motor vehicle on the basis of ensuring the recognition of the motor vehicle during driving, specifically, intelligently controlling the opening and closing of the daytime running light according to the actual state of the vehicle, avoiding unnecessary energy waste, and helping to achieve energy saving and emission reduction of the motor vehicle. In addition, it can also intelligently control the opening and closing of the daytime running light according to the actual state of the vehicle, making the use of the daytime running light more flexible and convenient, optimizing the user experience, and improving the user's satisfaction with the use of the motor vehicle.

[0139] It should be understood that, although the various steps in the flowcharts involved in the above-mentioned embodiments are displayed in sequence according to the indication of the arrows, these steps are not necessarily executed in sequence according to the order indicated by the arrows. Unless there is a clear explanation in this article, the execution of these steps does not have a strict order restriction, and these steps can be executed in other orders. Moreover, at least a part of the steps in the flowcharts involved in the above-mentioned embodiments can include multiple steps or multiple stages, and these steps or stages are not necessarily executed at the same time, but can be executed at different times, and the execution order of these steps or stages is not necessarily to be carried out in sequence, but can be executed in turn or alternately with other steps or at least a part of the steps or stages in other steps.

[0140] Based on the same inventive concept, the embodiment of the present application also provides a vehicle daytime running light control device for implementing the vehicle daytime running light control method involved above. The implementation scheme for solving the problem provided by the device is similar to the implementation scheme recorded in the above method, so the specific limitations in the embodiments of one or more vehicle daytime running light control devices provided below can refer to the limitations of the vehicle daytime running light control method above, and will not be repeated here.

[0141] In an exemplary embodiment, Figure 7 As shown, a control device 200 for a vehicle daytime running light is provided, comprising: a state recognition module 81, a control module 82 and a data acquisition module 83, wherein:

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

[0143] A control module 82, configured to turn on the daytime running lights based on a preset brightness of the current vehicle when the daytime running lights and the position lights are in an off state;

[0144] The data acquisition module 83 is used to acquire the current vehicle environment information, vehicle speed information and steering wheel angle information;

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

[0146] Specifically, the state recognition module 81 is used to obtain the state of the daytime running lights and the state of the position lights of the current vehicle, so that when it is detected that the position lights are in the off state, it knows that the daytime running lights will be turned on to improve the recognition of the current vehicle.

[0147] The control module 82 is used to call the preset brightness of the daytime running lights of the current vehicle to turn on the daytime running lights when it is learned that the daytime running lights and the position lights are both in the off state, so that the daytime running lights are in the luminous state.

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

[0149] The control module 82 is used to, after obtaining the current environment information, vehicle speed information and steering wheel angle information of the vehicle, select and obtain the vehicle speed information and steering wheel angle information that can be used to combine to obtain the target brightness of the daytime running lights based on the environment information, and then calculate the target brightness of the daytime running lights of the current vehicle based on the environment information and / or the vehicle speed information and / or the steering wheel angle information, and when the target brightness of the daytime running lights is determined, adjust the luminous brightness of the daytime running lights to the target luminous brightness; that is, after the daytime running lights are turned on, the application further calculates the most appropriate target brightness of the daytime running lights, so that the daytime running lights can be adjusted to the most appropriate target brightness as soon as possible after being turned on, thereby avoiding wasting vehicle energy, which is beneficial to reducing the energy consumption of motor vehicles on the basis of improving vehicle safety, thereby helping to improve the endurance of the vehicle; in addition, it can also avoid the situation where the initial luminous brightness is insufficient, so as to ensure that the turning on of the daytime running lights improves the vehicle recognition.

[0150] In an exemplary embodiment, the control module 82 is used to determine the target brightness of the daytime running lights based at least on the ambient light intensity, the light intensity threshold, the vehicle speed matching brightness and the steering wheel angle brightness when the environmental information indicates that the daytime running lights are in a sunny state; determine the target brightness of the daytime running lights based at least on the ambient light intensity, the light intensity threshold, the vehicle speed matching brightness, the steering wheel angle brightness, the rainfall and the rainfall light intensity threshold when the environmental information indicates that the daytime running lights are in a rainy state; determine the target brightness of the daytime running lights based at least on the ambient light intensity, the light intensity threshold, the vehicle speed matching brightness, the steering wheel angle brightness, the traffic volume brightness and the traffic volume light intensity threshold when the environmental information indicates that the daytime running lights are in a tunnel; wherein the vehicle speed matching brightness is the influence value of the current vehicle speed value on the target brightness of the daytime running lights, the steering wheel angle brightness is the influence value of the current vehicle steering wheel angle value on the target brightness of the daytime running lights, and the traffic volume brightness is the influence value of the current vehicle traffic volume size on the target brightness of the daytime running lights.

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