[0022] The present application will be described in more detail with reference to the embodiments. The following embodiments are presented by way of example and are not intended to limit the present application in any form. It should be noted that, for those of ordinary skill in the art, without departing from the concept of the present application, a number of modifications and improvements can be made. These all belong to the protection scope of the present application.

[0023] It should be understood that, when used in the specification and the appended claims of the present application, the term "comprising" indicates the presence of the described features, integers, steps, operations, elements, and / or components, but does not exclude the presence or addition of one or more other features, integers, steps, operations, elements, components, and / or groups thereof.

[0024] In the description of the specification and the appended claims of the present application, the terms "first", "second", "third", and the like are only used to distinguish the description, and cannot be understood as indicating or implying relative importance.

[0025] In the specification of the present application, the reference "one embodiment" or "some embodiments" and the like means that the specific features, structures or characteristics described in connection with the embodiment are included in one or more embodiments of the present application. Therefore, the statements "in one embodiment", "in some embodiments", "in other some embodiments", "in further some embodiments" and the like appearing in different places in the specification are not necessarily all referring to the same embodiment, but mean "one or more but not all embodiments", unless otherwise specifically emphasized. The terms "including", "containing", "having" and their variants mean "including but not limited to", unless otherwise specifically emphasized.

[0026] In addition, "a plurality of" mentioned in the embodiments of the present application should be interpreted as two or more.

[0027] The present inventors found that, in order to improve the experience and functional implementation effect of vehicle light, the vehicle body controller can be used to control each vehicle light in the vehicle. As the types of vehicle lights are increasing and the control methods are becoming more and more complex, additional controllers still need to be set in the light group to realize the corresponding logical functions, so that the control of vehicle lights is relatively complex and it is difficult to quickly and simply control the vehicle lights. Therefore, it is necessary to consider a new method for controlling vehicle lights.

[0028] In the embodiments of the present application, a register is arranged in the vehicle lamp, and the register stores the corresponding relationship between different control signals and the state of the vehicle lamp. When the vehicle lamp is controlled, the target vehicle lamp and the corresponding control signal are determined according to the acquired vehicle lamp control information, and then the corresponding target state of the target vehicle lamp is determined according to the corresponding relationship stored in the register, and the control of the vehicle lamp is directly performed, so that the controller in the vehicle lamp is not needed, the control process of the vehicle lamp is simplified, and the complexity of the control of the vehicle lamp is reduced.

[0029] Firstly, referring to FIG. 1, FIG. 1 schematically shows an application scenario provided by an embodiment of the present application, which involves a controller 11 and a plurality of vehicle lamps 12 on a vehicle.

[0030] In the application scenario shown in FIG. 1, the vehicle has a plurality of vehicle lamps 12, each of which includes a vehicle lamp body 121, a vehicle lamp actuator 122 and a register 123. The register 123 stores the corresponding relationship between different control signals and the state of the vehicle lamp body 121.

[0031] When the controller 11 acquires the vehicle lamp control information of the vehicle, the target vehicle lamp and the corresponding control signal are determined, and the control signal is sent to the target vehicle lamp. The state of the target vehicle lamp can be directly obtained according to the corresponding relationship stored in the register of the target vehicle lamp, and the target vehicle lamp can be directly controlled through the vehicle lamp actuator of the target vehicle lamp.

[0032] Optionally, the controller 11 can be a headlamp domain control unit (HDC), and the controller 11 can also be a vehicle controller, etc. Here, the controller 11 is taken as an example of the headlamp domain control unit, and the controller 11 is connected with the plurality of vehicle lamps in the vehicle.

[0033] Next, the vehicle lamp control method provided by an exemplary embodiment of the present application will be described with reference to FIGS. 2-4 in combination with the application scenario of FIG. 1. It should be noted that the above-mentioned application scenario is only shown for the purpose of facilitating the understanding of the spirit and principles of the present application, and the embodiments of the present application are not limited in this respect. On the contrary, the embodiments of the present application can be applied to any applicable scenario.

[0034] Referring to FIG. 2, FIG. 2 is a flowchart of the vehicle lamp control method provided by an embodiment of the present application. As shown in FIG. 2, the method in the embodiment of the present application can include the following steps.

[0035] In step 201, vehicle lamp control information of the vehicle at the current time is acquired.

[0036] For the above-mentioned vehicle lamp control information, in the embodiment, the vehicle lamp control information can be obtained from the host of the vehicle, such as the control instruction issued by the occupant in the vehicle received by the host of the vehicle, the occupant in the vehicle can control the vehicle lamp through the host of the vehicle; or the information generated according to the situation of the vehicle, such as the environment inside and outside the vehicle and the driving situation of the vehicle.

[0037] Here, the vehicle lamp control information can be input as input information to the HDC, and the control of the vehicle lamp is performed through the HDC. Among them, the transmission of the vehicle lamp control information can be realized through CAN (Controller Area Network) or Ethernet.

[0038] In step 202, according to the vehicle lamp control information, the target vehicle lamp to be controlled and the corresponding control signal are determined, and the control signal is output to the target vehicle lamp, so that the vehicle lamp actuator of the target vehicle lamp determines the target state corresponding to the control signal from the register of the target vehicle lamp, and adjusts the target vehicle lamp to the target state; wherein the register stores the corresponding relationship between different control signals and the state of the vehicle lamp.

[0039] In the embodiment, by analyzing the vehicle lamp control information, the target vehicle lamp to be controlled and the corresponding control signal can be obtained. Among them, the control signal can be the opening, closing, fault and brightness of the target vehicle lamp, etc. For example, it can be to turn on the target vehicle lamp, or to turn off the target vehicle lamp, or to adjust the brightness of the target vehicle lamp to 50%, etc.

[0040] Here, the HDC can also transmit the control signal to the corresponding target vehicle lamp through CAN or Ethernet. Since no controller is additionally arranged in the target vehicle lamp, the control signal can be directly transmitted to the vehicle lamp actuator in the target vehicle lamp, so that the vehicle lamp actuator controls the target vehicle lamp.

[0041] In addition, the register of the target vehicle lamp stores the corresponding relationship between different control signals and the state of the vehicle lamp, and the vehicle lamp controller can determine the state of the target vehicle lamp to be controlled according to the corresponding relationship stored in the register, so as to control the target vehicle lamp and adjust the state of the target vehicle lamp to the target state.

[0042] Optionally, the vehicle lamp control information of the vehicle at the current time in the embodiment includes the vehicle environment information of the vehicle at the current time. Here, the vehicle environment information can include the brightness inside the vehicle, the brightness outside the vehicle, the road information and the weather information of the position where the vehicle is located, etc.

[0043] The embodiment determines the target vehicle lamp to be controlled and the corresponding control signal according to the vehicle lamp control information. The vehicle lamp control information can be used to determine all vehicle lamps to be controlled and the corresponding control signals in the vehicle, and the priority of each vehicle lamp can be determined based on the preset vehicle lamp priority. The target vehicle lamp can be determined from all vehicle lamps according to the priority of each vehicle lamp and the priority threshold, and the control signal of the target vehicle lamp can be determined from the control signals corresponding to all vehicle lamps.

[0044] In the embodiment, the vehicle environment information is analyzed to find the vehicle lamp to be controlled or adjusted in the current environment, so as to meet the needs of the passengers in the vehicle and ensure safe driving.

[0045] In the embodiment, the vehicle environment information is analyzed to find whether the vehicle lamp needs to be turned on or off, and the brightness of the vehicle lamp needs to be adjusted, so as to meet the needs of the passengers in the vehicle. The vehicle lamp to be adjusted is the target vehicle lamp, and the direction of adjustment is the target state corresponding to the control signal.

[0046] For example, when the brightness outside the vehicle is low and affects the safety of driving, the target vehicle lamp can be the headlamp of the vehicle, and the control signal can be to turn on the headlamp of the vehicle. For another example, when the brightness outside the vehicle is low and the brightness inside the vehicle is high, the target vehicle lamp can be the headlamp of the vehicle and the interior lamp (such as reading lamp and illuminating lamp, etc.), and the control signal can be to turn on the headlamp of the vehicle, turn off the interior lamp, or adjust the brightness of the interior lamp to be low, etc. For another example, when driving in foggy weather, the brightness outside the vehicle is low and affects the driver's vision, the target vehicle lamp can be the fog lamp, and the control signal can be to turn on the fog lamp. Correspondingly, when driving in overcast, rainy and snowy weather, the target vehicle lamp can be the headlamp of the vehicle, and the control signal can be to turn on the headlamp of the vehicle to ensure safe driving.

[0047] Since there can be multiple target vehicle lamps, the emergency degree of each vehicle lamp to the current vehicle environment is different, and considering the allocation of memory resources of the controller, the vehicle lamp with higher emergency degree can be started first to meet the basic needs of the passengers in the vehicle and the safe driving of the vehicle.

[0048] Here, the priority of each vehicle lamp of the vehicle can be set according to the importance of the vehicle lamp. For example, the priority of the vehicle lamp A can be set to 1, the priority of the vehicle lamps B and C can be set to 2, the priority of the vehicle lamp D can be set to 3, and so on, and the priority of the vehicle lamp L can be set to 9, etc. The larger the value of the priority of the vehicle lamp, the lower the priority of the vehicle lamp, and the lower the importance of the vehicle lamp.

[0049] In addition, the importance of the vehicle lamp is different in different environments of the vehicle, and the priority of the vehicle lamp can be set according to the vehicle environment.

[0050] For example, when the vehicle is running, the priority of the vehicle exterior lighting lamp is higher than the priority of the vehicle interior lighting lamp when the brightness outside the vehicle is low, and in addition, the priority of the vehicle lamp for external collision warning can also be higher than the priority of the vehicle lamp for external lighting, so as to timely warn and ensure the safe driving of the vehicle.

[0051] Different priorities can also be set for the vehicle lamps inside the vehicle, such as the priority of the vehicle lamp for fatigue driving being higher than the priority of the vehicle lamp for interior lighting.

[0052] When the vehicle is stopped, such as in a camping mode, the priority of the vehicle lamp for interior lighting can be higher than the priority of the vehicle lamp for exterior lighting, so as to provide the necessary lighting for the passengers in the vehicle.

[0053] In this embodiment, a priority threshold can be set, and for the vehicle lamps with a priority lower than the priority threshold, the control is preferentially performed, and the adjustment of the corresponding vehicle lamp is timely implemented, so as to ensure the driving safety and the experience of the user. For example, the priority threshold can be set to 3, and the vehicle lamps with a priority less than or equal to 3 can be taken as the target vehicle lamps.

[0054] Optionally, in this embodiment, all the vehicle lamps that need to be controlled in the vehicle and the corresponding control signals are determined according to the vehicle environment information. The identity of the driver of the vehicle can be acquired first, and based on the identity, the corresponding safe driving vehicle environment information of the driver of the vehicle is determined from the pre-stored safe driving vehicle environment information of the driver. Then, the recommended vehicle lamp combination of the vehicle at the current time is determined according to the difference between the vehicle environment information and the safe driving vehicle environment information of the driver of the vehicle. The recommended vehicle lamp combination includes the recommended vehicle lamp and the recommended state of each recommended vehicle lamp. Finally, the recommended vehicle lamp combination is displayed, and if a selection instruction is acquired, all the vehicle lamps that need to be controlled in the vehicle and the corresponding control signals are determined according to the selection instruction and the recommended vehicle lamp combination.

[0055] In this embodiment, by comparing the difference between the vehicle environment information and the safe driving vehicle environment information of the driver, the recommended vehicle lamp combination of the vehicle can be determined, the vehicle lamp suitable for the vehicle environment information at the current time can be found, and the difference between the vehicle environment information and the safe driving vehicle environment information of the driver is reduced, so as to ensure the safe driving of the driver.

[0056] The identity of a plurality of drivers and the safe driving vehicle environment information of each driver can be pre-stored in the vehicle. The safe driving vehicle environment information of the driver can be information that the driver can achieve good safe driving when the brightness outside the vehicle is a preset brightness, or can include other environment information, such as road information, brightness outside the vehicle when turning, or the use of the vehicle lamp when entering or exiting a tunnel, etc.

[0057] Here, for each driver, the environment information of the vehicle driven safely can be determined by the environment information of the vehicle driven safely by the driver in the past period of time.

[0058] In this embodiment, the identity of the driver can be determined by capturing the driver by the camera to determine the driver of the vehicle, and finding the corresponding identity.

[0059] In order to narrow the difference between the vehicle environment information and the environment information of the vehicle driven safely by the driver, ensure the safe driving of the driver, adjust the corresponding vehicle light, and obtain the recommended vehicle light combination. When the brightness in the vehicle environment information is higher than the brightness in the environment information of the vehicle driven safely, the vehicle light can be turned off or the brightness of the vehicle light can be reduced, and the recommended vehicle light combination can be the vehicle headlight, and the corresponding recommended state can be turning off the vehicle headlight or adjusting the brightness of the vehicle headlight.

[0060] Here, the recommended vehicle light combination can be displayed for the driver of the vehicle to select and determine, on the one hand, the driver can be reminded of the upcoming environmental change, and on the other hand, the driver can be allowed to select whether to adjust the vehicle light, and in the case that the driver meets the demand, the corresponding adjustment can be not performed, reducing the waste of memory resources in the controller.

[0061] In addition, the recommended vehicle light combination can be multiple, and the driver can select the combination needed according to the current feeling.

[0062] Since the driving habits of various drivers are different, the recommended vehicle light combination can also be obtained by learning the use of the vehicle light by the driver in the process of driving the vehicle in the previous period of time at the current time. Since part of the road is an accident-prone road, or the road can be a type that the current driver has not driven, the use of the vehicle light by multiple users in the driving process in the target road section can be learned to determine the corresponding recommended vehicle light combination.

[0063] In some embodiments, the selection instruction carries an identity of the selected vehicle light.

[0064] In this embodiment, according to the selection instruction and the recommended vehicle light combination, all vehicle lights that need to be controlled in the vehicle and the corresponding control signals can be determined by first obtaining the current state of the selected vehicle light in the vehicle at the current time according to the identity of the selected vehicle light, and then determining the recommended state corresponding to the selected vehicle light according to the recommended vehicle light combination; and then determining the selected vehicle light with different current state and corresponding recommended state as the target vehicle light, and obtaining the control signal corresponding to the target vehicle light based on the current state and the corresponding recommended state.

[0065] In the embodiment, only the target vehicle light whose current state is different from the recommended state is controlled, so that the target vehicle light to be controlled is reduced, the data to be processed by the controller is reduced, and the resources consumed by the controller is reduced.

[0066] In the embodiment, the recommended vehicle light combination can include turning on the vehicle light A, and the vehicle light A of the vehicle is already in the turned-on state. At this time, sending a control instruction to the vehicle light A is obviously an invalid instruction, and the resources of the controller are wasted. Therefore, the current state of the selected vehicle light in the vehicle is acquired first, the current state and the recommended state of the selected vehicle light are compared, only the selected vehicle light whose state is different is controlled, the number of control instructions sent to the vehicle light is reduced, and the complexity of the control is reduced.

[0067] Here, the current state of the target vehicle light is different, and the corresponding control signal can also be changed. For example, the recommended state of the target vehicle light is 60% brightness, if the current state of the target vehicle light is the turned-off state, the corresponding control signal can be to turn on the target vehicle light at 60% brightness; if the current state of the target vehicle light is the turned-on state and the brightness is 30%, the corresponding control signal can be to adjust the brightness of the target vehicle light to 60%.

[0068] In some embodiments, after the target vehicle light to be controlled and the corresponding control signal are determined according to the vehicle light control information, the associated vehicle light related to the target vehicle light can be determined from the vehicle lights; the priority of the associated vehicle light is determined according to the preset vehicle light priority; if the priority of the target vehicle light is higher than the priority of the associated vehicle light, the state of the associated vehicle light at the current time is acquired; it is judged whether the state of the associated vehicle light at the current time conflicts with the state of the target vehicle light corresponding to the control signal; if there is a conflict, the state of the conflicting associated vehicle light is adjusted so that the state of the adjusted associated vehicle light does not conflict with the state of the target vehicle light corresponding to the control signal.

[0069] In the embodiment, when the state of the target vehicle light conflicts with the state of the associated vehicle light at the current time, the associated vehicle light is adjusted so that the function of the target vehicle light can be fully realized.

[0070] Here, the associated vehicle light can be a vehicle light close to the target vehicle light, for example, a vehicle light with a distance less than a preset distance from the target vehicle light can be determined as the associated vehicle light of the target vehicle light. In addition, the associated vehicle light can affect the use or display of the target vehicle light. For example, an automatic driving vehicle light and a vehicle lighting lamp are provided on the vehicle, and if the distance between the two vehicle lights is less than a preset distance, the display of the two vehicle lights can affect each other, and the two vehicle lights can be associated with each other.

[0071] In the embodiment, the priority of the target vehicle lamp can be compared with the priority of the associated vehicle lamp. If the priority of the target vehicle lamp is higher than the priority of the associated vehicle lamp, it indicates that the target vehicle lamp is more important and the demand of the target vehicle lamp needs to be met in priority. Therefore, it can be further determined whether the state of the target vehicle lamp conflicts with the state of the associated vehicle lamp at the current time. In the case of conflict, the target vehicle lamp is given priority and the associated vehicle lamp is adjusted so that the function of the target vehicle lamp can be fully realized.

[0072] For example, an automatic driving vehicle lamp and a vehicle lighting lamp are provided on the vehicle, and the two vehicle lamps are associated with each other. The priority of the automatic driving vehicle lamp is higher than the priority of the vehicle lighting lamp. During automatic driving of the vehicle, the target vehicle lamp, i.e., the automatic driving vehicle lamp, needs to be turned on to remind surrounding vehicles. If the state of the vehicle lighting lamp conflicts with the state of the automatic driving vehicle lamp, for example, the vehicle lighting lamp is in an open state and has a high brightness, in order to remind surrounding vehicles, part of the vehicle lighting lamp or the lamp bead associated with the automatic driving vehicle lamp can be turned off, or the brightness can be adjusted to be lower, under the premise of meeting the vehicle lighting, the automatic driving vehicle lamp is highlighted to realize the reminding function of the automatic driving vehicle lamp.

[0073] In addition, if the priority of the target vehicle lamp is lower than the priority of the associated vehicle lamp, the target vehicle lamp can be directly controlled.

[0074] In some embodiments, after the control signal is output to the target vehicle lamp, the vehicle environment information at the next time can be acquired first; the next time is separated from the current time by a preset time; then the vehicle environment information at the next time is compared with the vehicle environment information at the current time; if the difference between the vehicle environment information at the next time and the vehicle environment information at the current time exceeds a preset environment difference range, the steps of determining all vehicle lamps that need to be controlled in the vehicle and corresponding control signals according to the vehicle environment information, and obtaining the priority of all vehicle lamps based on the preset priority of the vehicle lamp are re-executed based on the vehicle environment information at the next time.

[0075] In the embodiment, the vehicle environment information is acquired in real time to control the vehicle lamp in real time. When the vehicle environment changes, the corresponding vehicle lamp is controlled in time.

[0076] In the embodiment, by comparing the vehicle environment information at the next time with the vehicle environment information at the current time, it can be determined whether the environment in which the vehicle is located changes, so that the corresponding vehicle lamp is controlled in time when the vehicle environment changes. In the embodiment, the preset environment difference range can be determined according to the difference between different vehicle environment information.

[0077] For example, when the vehicle enters or exits a tunnel or an underground parking lot, the brightness outside the vehicle in the vehicle environment information will change abruptly. When the brightness changes from high to low, i.e., when the vehicle enters the tunnel or the underground parking lot, the vehicle headlamp can be turned on; or when the brightness changes from low to high, i.e., when the vehicle exits the tunnel or the underground parking lot, the vehicle headlamp can be turned off.

[0078] In some embodiments, after determining the target vehicle lamp to be controlled and the corresponding control signal according to the vehicle lamp control information, the actual state of the target vehicle lamp in the vehicle can be obtained; and it is determined whether the actual state is the same as the target state corresponding to the target vehicle lamp in the vehicle lamp control information; if the actual state is different from the target state corresponding to the target vehicle lamp in the vehicle lamp control information, the fault information of the target vehicle lamp is determined and a prompt is given.

[0079] In this embodiment, detecting the actual state of the target vehicle lamp can determine whether the target vehicle lamp has executed the corresponding control signal, and determine whether there is a fault in the target vehicle lamp in time.

[0080] In this embodiment, the actual state of the target vehicle lamp is detected after the target vehicle lamp is controlled, to detect whether the target vehicle lamp has executed the corresponding control signal.

[0081] Here, if the actual state of the target vehicle lamp is different from the target state, it means that the target vehicle lamp has not executed the corresponding control signal, which may be due to a fault in the target vehicle lamp. The fault information can be displayed to remind the driver or the passenger in the vehicle that the target vehicle lamp has a fault. In addition, the target vehicle lamp fault can also be reminded in the form of voice broadcast.

[0082] In this embodiment, based on the vehicle light control information, the target vehicle light to be controlled and the corresponding control signal are determined, and the control signal is output to the target vehicle light. This allows for centralized control of the entire vehicle's lighting and joint processing of vehicle lighting control and vehicle perception data, improving the convenience of vehicle lighting use. Specifically, a vehicle light actuator and register are installed at the vehicle light location. The register determines the state corresponding to the vehicle light control signal, allowing direct control of the vehicle light state via the actuator without the need for an additional controller. This centralized control of all vehicle lights reduces the complexity of vehicle lighting control, enabling quick and easy control of vehicle lights. This method analyzes vehicle environmental information to identify headlights that need control or adjustment in the current environment to meet the needs of vehicle occupants and ensure safe driving. By comparing the differences between the vehicle's environmental information and the environmental information of the driver's safe driving vehicle, a recommended headlight combination can be determined, finding headlights suitable for the current vehicle environment and reducing the discrepancy between the vehicle's environmental information and the driver's corresponding safe driving vehicle environment, thus ensuring safe driving. It also considers associated headlights related to the target headlight; when the state of the target headlight conflicts with the state of an associated headlight at the current moment, the associated headlight is adjusted to ensure the target headlight's function is fully realized. Based on this, the method provided in this application can centralize the control of all vehicle lights in a controller, reducing the complexity of vehicle lighting control and enabling quick and easy control of vehicle lights.

[0083] Furthermore, in determining the target vehicle light to be controlled, this application embodiment can also consider the vehicle mode or scenario, etc., to determine whether the vehicle needs light control. Only when light control is required will subsequent steps be executed, reducing the controller's workload and achieving simple and accurate control of the target vehicle light. Figure 3 is a flowchart illustrating a vehicle light control method provided in another embodiment of this application. As shown in Figure 3, the method includes:

[0084] Step 301: Obtain the vehicle's headlight control information at the current moment.

[0085] Here, the implementation of step 301 can be found in the relevant description in the embodiment of Figure 2, and will not be repeated here.

[0086] Step 302: Determine whether the vehicle meets the preset headlight triggering conditions; wherein, the preset headlight triggering conditions are determined based on the scenarios in which multiple headlights are used.

[0087] The preset vehicle lamp triggering condition can be a vehicle mode in which the vehicle is located, such as a driving mode, a stopping mode, a camping mode, a viewing mode, and the like, or can be a specific scene in which the vehicle lamp is used in the vehicle, and can include a straight driving scene, a turning scene, a lane changing scene, a following scene, and the like, and can further include a tunnel driving scene, a foggy weather driving scene, an overcast weather driving scene, a rainy and snowy weather driving scene, and the like, and can further be a warning scene, such as a collision warning scene, a lane line deviation warning scene, an overspeed warning scene, and the like.

[0088] In the above vehicle modes and scenes, the vehicle lamp needs to be controlled, for example, when the viewing mode is entered, the interior lighting lamp can be turned off so that the passengers in the vehicle can view; after the camping mode is entered, the lighting lamp of the vehicle can be turned on for illumination. For example, when the vehicle needs to turn, the corresponding turn signal lamp can be turned on to remind the surrounding vehicles; when driving in rainy and snowy weather, the front lamp of the vehicle can be turned on for illumination.

[0089] In addition, the preset vehicle lamp triggering condition can be obtained by learning the use of the vehicle lamp by the driver in the process of driving the vehicle in the previous period at the current time. For example, when driving on a relatively narrow road at night, the driver generally controls the vehicle lamp to project a light blanket with the same width as the vehicle to assist driving, and when the driver drives the vehicle on a relatively narrow road at night, that is, the preset vehicle lamp triggering condition is reached, the subsequent steps can be performed.

[0090] The preset vehicle lamp triggering condition can also be obtained by learning the use of the vehicle lamp by multiple users in the process of driving on a target road section, and can also be obtained by learning the use of the vehicle lamp by multiple users in the process of driving in a period of time.
