Description

Technical Field

[0001] The present invention relates to the technical field of door light control, and specifically relates to a door light control method, device, system, and target vehicle. Background Art

[0002] With the increasing degree of automotive electronics intelligence, different types of controllers are increasing day by day. There are more and more scenarios where multiple controller nodes coexist on the same vehicle and message information is closely interacted. Currently, in order to provide users with a more comfortable and gentle light-sensitive experience, the door lights in the automotive interior usually adopt a control method of gradually brightening and dimming. Therefore, it is necessary to use PWM (Pulse Width Modulation) waveforms for adjustment, mainly controlling the duty cycle of the waveform.

[0003] Currently, the traditional control of gradually brightening and dimming the door lights generally triggers the lights to gradually brighten when the door is opened or the door light switch is turned on, and triggers the lights to gradually dim when the door is closed or the door light switch is turned off. However, it can only follow a fixed gradually brightening and dimming time pattern from off to on or from on to off.

[0004] Therefore, how to flexibly control vehicle lights has become an urgent problem to be solved. Summary of the Invention

[0005] In view of this, the present invention provides a door light control method, device, system, and target vehicle to solve the problem of how to flexibly control vehicle lights.

[0006] In a first aspect, the present invention provides a door light control method, which is applied to a first electronic device in a door light control system. The door light control system includes a first electronic device and a second electronic device, and the first electronic device and the second electronic device are communicatively connected. The method includes:

[0007] Receiving a door light control message sent by the second electronic device;

[0008] Identifying the door light control message to determine the driver's door light control information and the co-driver's door light control information in the door light control message;

[0009] Controlling the driver's door light and the co-driver's door light respectively according to the driver's door light control information and the co-driver's door light control information.

[0010] In the door light control method provided by the embodiment of the present application, the first electronic device can receive the door light control message sent by the second electronic device. Then, identify the door light control message to determine the driver's door light control information and the co-driver's door light control information in the door light control message. This ensures the accuracy of the driver's door light control information and the co-driver's door light control information in the determined door light control message. Then, control the driver's door light and the co-driver's door light respectively according to the driver's door light control information and the co-driver's door light control information, so that the driver's door light and the co-driver's door light can be controlled respectively according to the door light control message, and flexible control of the driver's door light and the co-driver's door light can be achieved. Therefore, it is not necessary to fixedly set the time for the door light to gradually brighten and dim, as well as the period and frequency of generating the PWM wave, that is, trigger the light to gradually brighten and dim when a door is opened or closed. Therefore, the door light control method can be from off to on or from on to off in a non-fixed time mode, and in addition, it can interact with the message information of the second electronic device, so the interference and control of the process of the door light gradually brightening and dimming are realized.

[0011] In an alternative embodiment, controlling the driver's door light and the co-driver's door light respectively according to the driver's door light control information and the co-driver's door light control information includes:

Then, the current control signals corresponding to the main driver's door light and the co-driver's door light are respectively interrupted, so that the first PWM signal corresponding to the main driver's door light can be controlled according to the first door light gradual brightening start value, the first door light gradual brightening end value and the first door light gradual brightening time, ensuring the accuracy of controlling the first PWM signal corresponding to the main driver's door light. And according to the second door light gradual brightening start value, the second door light gradual brightening end value and the second door light gradual brightening time, the second PWM signal corresponding to the co-driver's door light is controlled, ensuring the accuracy of controlling the second PWM signal corresponding to the co-driver's door light. In addition, in the above method, the door light is controlled to turn on and off by integrating the door signal of the first electronic device and the door light control message sent by the second electronic device, which can keep the original nodes of the whole vehicle unchanged and only serve as the second supply (the second supplier, not the only and main supplier of a certain product function of the customer). However, even as the second supply, the possibility of replacing the original node can be obtained because the door light control logic of the original node has been merged.

[0069] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are some, but not all, of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0070] As the degree of automotive electronics intelligence becomes higher and higher, different types of controllers are increasing day by day. There are more and more scenarios where multiple controller nodes coexist on the same vehicle and message information is closely interacted. Currently, in order to give users a more comfortable and gentle light-sensing experience for the door lights in the automotive interior, a gradually brightening and dimming control method is usually adopted. Therefore, PWM waveforms are required for adjustment, mainly for controlling the duty cycle of the waveforms.

[0071] As is well known, the PWM period is the time from the high-level time to the low-level time, and is inversely proportional to its PWM frequency. The PWM duty cycle is the ratio of the high-level time to the total time in one cycle. The basic principle of PWM generation is shown in Figures 1(a) and 1(b), namely the area equivalence method. The gradually brightening time refers to the rising time of the first half of the sine curve in Figure 1(a), while the gradually dimming corresponds to the falling time of the second half. Generally, the PWM period (switching period) is much smaller than the scheduling period of the embedded software, which is 10 ms. When the duty cycle in Figure 1(b) is 100%, the output of a is high level. When the duty cycle of b is other values in one cycle, the sine wave areas generated according to definite integrals are different. When the duty cycles are different in multiple cycles, different area waveforms will be generated, that is, an analog signal is generated, and the door lights also generate a gradual change according to the analog signal. When the frequency is too small, the time of one cycle is too long, and the process of the lamp turning on and off can be seen with the naked eye; when the frequency is high enough, the speed of the lamp turning on and off cannot catch up with the switching speed (the lamp goes out before it is fully lit). Due to the persistence of vision, the human eye does not feel that the lamp is flickering, but feels that the brightness of the lamp has decreased, thus achieving a gradual change effect. Therefore, if other controller nodes want to intervene in the gradual brightening and dimming of the door lights of the DCS (Distributed Control System) node, the core is to control the duty cycle of the PWM wave output by the DCS as the input signal for controlling the door lights.

[0072] Currently, the traditional control of the gradual brightening and dimming of door lights generally triggers the lamp to gradually brighten when the door is opened or the door light switch is turned on, and triggers the lamp to gradually dim when the door is closed or the door light switch is turned off. However, it can only gradually brighten or dim from off to on or from on to off according to a fixed gradual brightening and dimming time mode.

[0073] Therefore, how to flexibly control vehicle lights has become an urgent problem to be solved.

[0074] According to an embodiment of the present invention, an embodiment of a door light control method is provided. It should be noted that the steps shown in the flowchart of the accompanying drawings can be executed in a computer system such as a set of computer-executable instructions. And although the logical order is shown in the flowchart, in some cases, the steps shown or described can be executed in a different order than here.

[0075] In this embodiment, a door light control method is provided, including a first electronic device in a door light control system. The door light control system includes a first electronic device and a second electronic device, and the first electronic device and the second electronic device are communicatively connected. Figure 2 It is a flowchart of the door light control method according to an embodiment of the present invention, as Figure 2 shown, and this process includes the following steps:

[0076] Step S101, receive a door light control message sent by the second electronic device.

[0077] Specifically, the first electronic device can receive the door light control message sent by the second electronic device based on the communication connection with the second electronic device.

[0078] Among them, it should be noted that the second electronic device can generate a door light control message according to the current state information of the target vehicle corresponding to the second electronic device.

[0079] Step S102, identify the door light control message to determine the driver's door light control information and the co-driver's door light control information in the door light control message.

[0080] Specifically, the first electronic device can identify the door light control message to determine the driver's door light control information and the co-driver's door light control information in the door light control message.

[0081] Step S103, control the driver's door light and the co-driver's door light respectively according to the driver's door light control information and the co-driver's door light control information.

[0082] Specifically, the first electronic device can identify the driver's door light control information and the co-driver's door light control information respectively to determine the first control signal included in the driver's door light control information and the second control signal included in the co-driver's door light control information. Then, control the driver's door light according to the first control signal and control the co-driver's door light according to the second control signal.

[0083] This step will be introduced in detail below.

[0084] In the embodiment of the present application, for the door light control method, the first electronic device can receive the door light control message sent by the second electronic device. Then, identify the door light control message to determine the driver's door light control information and the co-driver's door light control information in the door light control message, ensuring the accuracy of the driver's door light control information and the co-driver's door light control information in the determined door light control message. Then, according to the driver's door light control information and the co-driver's door light control information, control the driver's door light and the co-driver's door light respectively, so that the driver's door light and the co-driver's door light can be controlled according to the door light control message, and flexible control of the driver's door light and the co-driver's door light can be achieved. Thus, it is not necessary to fixedly set the time for the door light to gradually brighten and dim, as well as the period and frequency of generating the PWM wave, that is, trigger the light to gradually brighten and dim when a door is opened or closed. Therefore, this door light control method can be from off to on or from on to off not in a fixed-time mode. In addition, it can interact with the message information of the second electronic device, so the interference and control of the process of the door light gradually brightening and dimming are realized.

[0085] In this embodiment, a door light control method is provided. For the first electronic device in the door light control system, the door light control system includes the first electronic device and the second electronic device, and the first electronic device and the second electronic device are communicatively connected. Figure 3 It is a flowchart of the door light control method according to the embodiment of the present invention, as Figure 3 shown, and this process includes the following steps:

[0086] Step S201, receive the door light control message sent by the second electronic device.

[0087] For this step, please refer to the introduction of step S101 above and will not be elaborated here.

[0088] Step S202, identify the door light control message to determine the driver's door light control information and the co-driver's door light control information in the door light control message.

[0089] For this step, please refer to the introduction of step S102 above and will not be elaborated here.

[0090] Step S203, according to the driver's door light control information and the co-driver's door light control information, control the driver's door light and the co-driver's door light respectively.

[0091] Specifically, the above step S203 may include the following steps:

[0092] Step S2031: Identify the driver's door light control information and the co-driver's door light control information respectively, determine the first door light gradual brightening start value, the first door light gradual brightening end value, and the first door light gradual brightening time corresponding to the driver's door light control information, and determine the second door light gradual brightening start value, the second door light gradual brightening end value, and the second door light gradual brightening time corresponding to the co-driver's door light control information.

[0093] Specifically, the first electronic device can identify the driver's door light control information and the co-driver's door light control information respectively, determine the first door light gradual brightening start value, the first door light gradual brightening end value, and the first door light gradual brightening time corresponding to the driver's door light control information, and determine the second door light gradual brightening start value, the second door light gradual brightening end value, and the second door light gradual brightening time corresponding to the co-driver's door light control information.

[0094] Step S2032: Interrupt the current control signals corresponding to the driver's door light and the co-driver's door light respectively.

[0095] Specifically, the first electronic device can call the interrupt function to interrupt the current control signals corresponding to the driver's door light and the co-driver's door light respectively.

[0096] Step S2033: Control the first PWM signal corresponding to the driver's door light according to the first door light gradual brightening start value, the first door light gradual brightening end value, and the first door light gradual brightening time.

[0097] Specifically, the first electronic device can calculate the duty cycles of the first PWM signal at the start and end according to the first door light gradual brightening start value and the first door light gradual brightening end value.

[0098] Among them, the first door light gradual brightening start value and the first door light gradual brightening end value can be 0 - 100. Exemplarily, if the gradual brightening is from low brightness to high brightness, the starting duty cycle should be close to 0%, and the ending duty cycle should be close to 100%. If the gradual brightening is from high brightness to low brightness, it is the opposite.

[0099] Then, the first electronic device calculates the period of the first PWM signal according to the first door light gradual brightening time.

[0100] The period of the first PWM signal = the first door light gradual brightening time / (the reciprocal of the PWM frequency).

[0101] Among them, the period of the first PWM signal is the minimum time unit for the PWM signal to repeat. The first door light gradual brightening time refers to the time required from the starting brightness to the ending brightness.

[0102] Then, the first electronic device generates the first PWM signal according to the calculated duty cycle and period of the first PWM signal. For example, if the PWM period is 1 second and the duty cycle is 50%, then within each 1-second period, the output pin remains high for 0.5 seconds.

[0103] Step S2034, control the second PWM signal corresponding to the co-pilot door light according to the second door light gradual brightening start value, the second door light gradual brightening end value, and the second door light gradual brightening time.

[0104] Specifically, the first electronic device can calculate the duty cycles of the second PWM signal at the start and end according to the second door light gradual brightening start value and the second door light gradual brightening end value.

[0105] Among them, the second door light gradual brightening start value and the second door light gradual brightening end value can be 0 - 100. Exemplarily, if the gradual brightening is from low brightness to high brightness, the starting duty cycle should be close to 0%, and the ending duty cycle should be close to 100%. If the gradual brightening is from high brightness to low brightness, it is the opposite.

[0106] Then, the first electronic device calculates the period of the second PWM signal according to the second door light gradual brightening time.

[0107] The period of the second PWM signal = the second door light gradual brightening time / (the reciprocal of the PWM frequency).

[0108] Among them, the period of the second PWM signal is the minimum time unit for the PWM signal to repeat. The second door light gradual brightening time refers to the time required from the starting brightness to the ending brightness.

[0109] Then, the first electronic device generates the second PWM signal according to the calculated duty cycle and period of the second PWM signal. For example, if the PWM period is 1 second and the duty cycle is 50%, then within each 1-second period, the output pin remains high for 0.5 seconds.

[0110] In the above method, the duty cycle of the adjustable door light PWM signal is realized, and it can be interrupted at any time when the door light control message changes. When interacting with other functions, the adaptive performance of the light brightness is better. The starting value / ending value, etc. of the duty cycle in the model are all configurable, and when there are requirement changes, directly modifying the code logic is avoided.

[0111] Step S204, monitor the driver's door and the co-pilot door.

[0112] Specifically, the first electronic device can detect whether the driver's door and the co-pilot door are fully closed through the door position sensor, and can also detect whether the driver's door and the co-pilot door are open or closed through the door switch sensor.

[0113] Step S205, if the driver's door changes from the closed state to the open state and the door light control message sent by the second electronic device is not received within the first preset duration, then control the first PWM signal corresponding to the driver's door light according to the first preset control signal.

[0114] and / or

[0115] Step S206, if the front passenger door changes from the closed state to the open state and the door light control message sent by the second electronic device is not received within the first preset duration, then control the second PWM signal corresponding to the front passenger door light according to the first preset control signal.

[0116] Specifically, if the driver's door changes from the closed state to the open state and the door light control message sent by the second electronic device is not received within the first preset duration, the first electronic device may control the first PWM signal corresponding to the driver's door light according to the first preset control signal.

[0117] Specifically, if the front passenger door changes from the closed state to the open state and the door light control message sent by the second electronic device is not received within the first preset duration, the first electronic device may control the second PWM signal corresponding to the front passenger door light according to the first preset control signal.

[0118] Among them, the first preset duration may be 2s or 3s. The embodiments of the present application do not make specific limitations on the first preset duration.

[0119] Among them, the first preset control signal may be to light up with a 100% duty cycle or other control signals. The embodiments of the present application do not make specific limitations on the first preset control signal.

[0120] Step S207, if the driver's door changes from the open state to the closed state and the door light control message sent by the second electronic device is not received within the first preset duration, then control the first PWM signal corresponding to the driver's door light according to the second preset control signal.

[0121] and / or

[0122] Step S208, if the front passenger door changes from the open state to the closed state and the door light control message sent by the second electronic device is not received within the first preset duration, then control the second PWM signal corresponding to the front passenger door light according to the second preset control signal.

[0123] Specifically, if the driver's door changes from the open state to the closed state and the door light control message sent by the second electronic device is not received within the first preset duration, the first electronic device controls the first PWM signal corresponding to the driver's door light according to the second preset control signal.

[0124] If the co-pilot door changes from the open state to the closed state and no door light control message sent by the second electronic device is received within the first preset duration, the first electronic device controls the second PWM signal corresponding to the co-pilot door light according to the second preset control signal.

[0125] Wherein, the second preset control signal can be to control extinguishing, or other control signals, and the embodiments of the present application do not make specific limitations on the first preset control signal.

[0126] Step S209, monitor the first PWM signal corresponding to the driver's door light and the second PWM signal corresponding to the co-pilot door light.

[0127] Specifically, the first electronic device can use a PWM decoder or the built-in PWM capture function of a microcontroller to read the periods and pulse widths of the first PWM signal and the second PWM signal.

[0128] Then, according to the read periods and pulse widths of the first PWM signal and the second PWM signal, detect whether the first PWM signal and the second PWM signal change within a preset duration.

[0129] Step S210, if the first PWM signal and the second PWM signal do not change within the second preset duration, control the driver's door light and the co-pilot door light to extinguish.

[0130] Specifically, if the first PWM signal and the second PWM signal do not change within the second preset duration, control the driver's door light and the co-pilot door light to extinguish. Thus, it can be realized that the door lights are timely turned off when people get on or off the vehicle, saving electricity.

[0131] Wherein, the second preset duration can be 5 minutes or 3 minutes, and the embodiments of the present application do not make specific limitations on the second preset duration.

[0132] The above method comprehensively controls the opening and closing of the driver's door light and the co-pilot door light together with the door switch state and the door light control message, rather than simply controlling the opening and closing of the driver's door light and the co-pilot door light directly according to the door state. In this way, it can not only ensure that the original controller uses the door signal to control the logic, but also incorporate the door light control message control idea of the new controller, and can intelligently control the lighting state of the door light. In addition, for the application on both sides of the door, with the idea of reusing one model, the control logics of the co-pilot door light control and the driver's door light control are the same, only replacing the driver's side door open state with the co-pilot side door open state when calling the code generated by the model.

[0133] The door light control method provided by the embodiment of the present application respectively identifies the main driver's door light control information and the co-driver's door light control information, determines the first door light gradual brightening start value, the first door light gradual brightening end value and the first door light gradual brightening time corresponding to the main driver's door light control information, and determines the second door light gradual brightening start value, the second door light gradual brightening end value and the second door light gradual brightening time corresponding to the co-driver's door light control information, ensuring the accuracy of the first door light gradual brightening start value, the first door light gradual brightening end value and the first door light gradual brightening time corresponding to the determined main driver's door light control information, and the accuracy of the second door light gradual brightening start value, the second door light gradual brightening end value and the second door light gradual brightening time corresponding to the co-driver's door light control information. Then, the current control signals corresponding to the main driver's door light and the co-driver's door light are respectively interrupted, so that the first PWM signal corresponding to the main driver's door light can be controlled according to the first door light gradual brightening start value, the first door light gradual brightening end value and the first door light gradual brightening time, ensuring the accuracy of controlling the first PWM signal corresponding to the main driver's door light. And according to the second door light gradual brightening start value, the second door light gradual brightening end value and the second door light gradual brightening time, the second PWM signal corresponding to the co-driver's door light is controlled, ensuring the accuracy of controlling the second PWM signal corresponding to the co-driver's door light. In addition, in the above method, the door light is controlled to turn on and off by integrating the door signal of the first electronic device and the door light control message sent by the second electronic device, which can keep the original nodes of the whole vehicle unchanged and only be used as a second supplier (the second supplier, not the only and main supplier of a certain product function of the customer). However, even as a second supplier, the possibility of replacing the original node can be obtained because the door light control logic of the original node has been merged.

[0134] In addition, the driver's door and the co-driver's door are monitored, so that the states of the driver's door and the co-driver's door can be accurately determined. If the driver's door changes from the closed state to the open state and no door light control message sent by the second electronic device is received within the first preset duration, the first PWM signal corresponding to the driver's door light is controlled according to the first preset control signal, ensuring the accuracy of controlling the first PWM signal corresponding to the driver's door light. And / or, if the co-driver's door changes from the closed state to the open state and no door light control message sent by the second electronic device is received within the first preset duration, the second PWM signal corresponding to the co-driver's door light is controlled according to the first preset control signal, ensuring the accuracy of controlling the second PWM signal corresponding to the co-driver's door light. If the driver's door changes from the open state to the closed state and no door light control message sent by the second electronic device is received within the first preset duration, the first PWM signal corresponding to the driver's door light is controlled according to the second preset control signal, ensuring the accuracy of controlling the first PWM signal corresponding to the driver's door light. And / or, if the co-driver's door changes from the open state to the closed state and no door light control message sent by the second electronic device is received within the first preset duration, the second PWM signal corresponding to the co-driver's door light is controlled according to the second preset control signal, ensuring the accuracy of controlling the second PWM signal corresponding to the co-driver's door light.

[0135] In addition, the first PWM signal corresponding to the driver's door light and the second PWM signal corresponding to the co-driver's door light are monitored, so that the changes of the first PWM signal corresponding to the driver's door light and the second PWM signal corresponding to the co-driver's door light can be obtained in a timely manner. If the first PWM signal and the second PWM signal do not change within the second preset duration, the driver's door light and the co-driver's door light are controlled to turn off, thus avoiding the waste of electricity caused by the user forgetting to turn off the lights.

[0136] The above method has wide generality and can realize the gradual brightening and dimming control of the same lamp by multiple controller nodes. It can also shield the interactive control information of other nodes through configuration items and only realize the gradual brightening and dimming control of its own node, rather than being limited to the control mode of a single controller. Subsequently, the software control logic development of non-own controller nodes for other lamp functions can be carried out according to this idea to improve the multi-functional experience of users.

[0137] To better introduce the door light control method provided by the embodiments of the present application, a specific implementation manner is provided in the embodiments of the present application. The duty cycle of the PWM wave designed in this patent is built by the Simulink Stateflow model, which can realize the real-time control of the gradual brightening and dimming processes of the driver's door light and the co-driver's door light by the door light control message of the second electronic device. The specific implementation steps are as follows:

[0138] 1. Sort out the input and output interfaces of the model. Among them, the requirements for the configuration item variables in the input interface should be considered as comprehensively as possible. For example, Figure 4 As shown in the figure, it is the structural block diagram of the PWM duty cycle model algorithm. Description of model input variables (configuration parameters. Use the same formal parameter variable to represent the start and end duty cycles and times of the driver side and the co-driver side, but use the door light control message signals of the driver side and the co-driver side respectively when integrating the code). Among them:

[0139] DoorEntryLightDPSStart: The starting value of the door light gradual brightening, configurable from 0 to 100.

[0140] DoorEntryLightDPSEnd: The ending value of the door light gradual brightening, configurable from 0 to 100.

[0141] DoorEntryLightDPSTime: The time for the door light to gradually brighten, 0ms, 10ms, 20ms, 50ms, 100ms, 200ms, 500ms, 1000ms, 5000ms, 10000ms.

[0142] The first three are signals in the InteriorDoorLightStatus_door light control message.

[0143] InteriorDoorLightStatus_OutTime: The timeout flag of the InteriorDoorLightStatus_door light control message, 0x0 / not timed out, 0x1 / timed out.

[0144] DriverDoorOpenStatus: The door lights on the driver side and the co-driver side controlled by the InteriorDoorLightStatus_door light control message are different signals in the same message. The door open status on the driver side, 0x0 / close, 0x1 / open. Hard wire signal. When it is collected as an abnormal value when used as a conditional judgment, it is processed as the door closed.

[0145] PassengerDoorOpenStatus: The door open status on the co-driver side, communication signal. Timeout processing: Treated as invalid.

[0146] DriverDoorLight: The main driver door light control, used to distinguish the driver side from the co-driver side during software integration.

[0147] PassengerDoor: The co-driver door light control.

[0148] Description of output variables:

[0149] DoorLight: The door light control signal / duty cycle, which is equivalent to the PWM duty cycle * 100, i.e., 0 - 10000.

[0150] It should be noted that the output value of this model is designed to be 100 times the duty cycle, which can be more accurate without decimals when calculating the increment per cycle in division. Therefore, it is also possible to save space by reducing the data unit of variables without using floating-point type data. Finally, when the model-generated code is integrated into the embedded code, the output value can be divided by 100 to convert it into a percentage.

[0151] According to the above requirements description, list the control logic and build the model:

[0152] The door light control logic module includes the door light gradually brightening state and the gradually dimming state. Meeting the prerequisite conditions and execution conditions, it controls the door light to gradually brighten and dim according to the signals in the InteriorDoorLightStatus_door light control message and the door switch signal.

[0153] The implementation logic description of the door light gradually brightening state: The door light gradually brightens, and the output ranges from the starting value of gradual brightening to the ending value of gradual brightening.

[0154] The implementation logic description of the door light gradually dimming state: The door light gradually dims, and the output fades from the ending value of gradual brightening to the starting value of gradual brightening.

[0155] (1) When the ECU receives the InteriorDoorLightStatus_door light control message, it controls the door light to gradually brighten and dim according to the starting duty cycle value: DoorEntryLightDSStart, the ending duty cycle value: DoorEntryLightDSEnd, and the time from the starting duty cycle to the ending duty cycle: DoorEntryLightDSTime. When any of the above messages changes, the gradual brightening and dimming process is interrupted, and the Doorlight value is updated.

[0156] (2) When the driver's door changes from open to closed and no InteriorDoorLightStatus_door light control message is received within 2 s (i.e., the timeout flag exists continuously for 2 s and this message is 0 before the door is closed), the door light goes out.

[0157] (3) When the driver's door changes from closed to open and no InteriorDoorLightStatus_door light control message is received within 2 s (i.e., the timeout flag exists continuously for 2 s and this message is 0 before the door is opened), the door light is 100% lit.

[0158] (4) When the door light continuously lights at a certain fixed brightness for 5 min, the door light goes out.

[0159] 4. Optimize the functions built in the above model to generate code.

[0160] 5. Integrate them into the embedded software separately on the driver's side and the co-driver's side.

[0161] 6. Conduct functional tests, track and optimize code defects.

[0162] Exemplarily, the technology described in this patent has been implemented in a certain project and tested on a real vehicle. For the door light in this project, the control frequency is 200HZ, the period is 0.005s, that is, 5ms, and the code execution period is 10ms (the two are not closely related). The duty cycle is up to 85% and the lowest is 0%, and the signal update period is 100ms. The test records of a certain scenario are as follows:

[0163] When the door is opened and meets the condition for the door light to light up, the door light gradually brightens. The door light control message updates the starting brightness, the ending brightness value, and the time for gradual brightening and dimming every 100ms. After the DCS receives this message, it changes with a duty cycle of 0 - 15 - 35 - 53 - 65 - 72 - 77 - 81 - 83 - 85 (which is also shown in the message in the form of a signal. The interval between these 10 values is 100ms, that is, the time for gradual brightening is 1000ms, 1s; and there are also 10 duty cycle values that change according to a certain rule between each two of these values). The door light control message finally maintains the starting brightness and the ending brightness signal values both at 85, and then the DCM controls the door light to output stably at 85%;

[0164] When the door light gradually dims, the starting brightness and the ending brightness of the door light control message signal will be exchanged, and the DCM is commanded to control the door light to change with a duty cycle of 85 - 70 - 50 - 31 - 19 - 12 - 8 - 6 - 4 - 2 - 1 - 0 (the interval between these 12 values is 100ms, that is, the time for gradual dimming is 1200ms), and finally it closes.

[0165] In this embodiment, a door light control method is provided, which is applied to the second electronic device in the door light control system. The door light control system includes a first electronic device and a second electronic device, and the first electronic device and the second electronic device are communicatively connected. As Figure 5 shown, the method includes:

[0166] Step S301, monitor the driver's door and the co-driver's door.

[0167] Specifically, the second electronic device can detect whether the driver's door and the co-driver's door are fully closed through the door position sensor, and can also detect whether the driver's door and the co-driver's door are open or closed through the door switch sensor.

[0168] Step S302, when it is monitored that the driver's door changes from the closed state to the open state, obtain the current interior environment brightness.

[0169] Specifically, when it is detected that the driver's door changes from the closed state to the open state, the second electronic device can detect the current brightness of the vehicle interior environment based on the ambient light sensor. The second electronic device can also use a light sensor inside the vehicle (such as a photoresistor or a photodiode) to detect the current brightness of the vehicle interior environment.

[0170] Step S303: Determine the main driver's door light control information corresponding to the driver's door based on the current brightness of the vehicle interior environment.

[0171] Specifically, the above step S303 may include the following steps:

[0172] Step S3031: Determine the starting value of the gradual brightening of the main driver's door light, the ending value of the gradual brightening of the main driver's door light, and the time for the gradual brightening of the main driver's door light corresponding to the driver's door based on the current brightness of the vehicle interior environment, and generate the main driver's door light control information.

[0173] Specifically, the second electronic device can set a minimum preset brightness threshold and a maximum preset brightness threshold. When the current brightness of the vehicle interior environment is lower than the minimum preset brightness threshold, the main driver's door light starts to gradually brighten; when the current brightness of the vehicle interior environment is higher than the maximum preset brightness threshold, the main driver's door light stops gradually brightening.

[0174] When the current brightness of the vehicle interior environment is lower than the minimum preset brightness threshold, the main driver's door light starts to gradually brighten. The starting value of the gradual brightening of the first door light can be any value between the main driver's door light being completely closed (0%) and completely open (100%). Optionally, the starting value of the gradual brightening of the first door light can be the minimum preset brightness threshold or other values.

[0175] When the current brightness of the vehicle interior environment is higher than the maximum preset brightness threshold, the main driver's door light stops gradually brightening, and the ending value of the gradual brightening of the first door light is usually the door light being completely closed (0%).

[0176] Among them, the time for the gradual brightening of the first door light can be set according to the difference between the minimum preset brightness threshold and the maximum preset brightness threshold. The greater the difference between the minimum preset brightness threshold and the maximum preset brightness threshold, the longer the time for the gradual brightening of the first door light.

[0177] It should be noted that the minimum preset brightness threshold and the maximum preset brightness threshold can be set according to user requirements.

[0178] and / or

[0179] Step S304: When it is detected that the co-driver's door changes from the closed state to the open state, obtain the current brightness of the vehicle interior environment.

[0180] Step S305: Determine the co-driver's seat door light control information corresponding to the co-driver's door based on the current brightness of the vehicle interior environment.

[0181] Specifically, the above step S305 may include the following steps:

[0182] Step S3051: Based on the current in-vehicle ambient brightness, determine the starting value, ending value, and fading-in time of the second door light corresponding to the co-driver's door, and generate co-driver's seat door light control information.

[0183] Specifically, the second electronic device may set a minimum preset brightness threshold and a maximum preset brightness threshold. When the current in-vehicle ambient brightness is lower than the minimum preset brightness threshold, the driver's door light starts to fade in; when the current in-vehicle ambient brightness is higher than the maximum preset brightness threshold, the driver's door light stops fading in.

[0184] When the current in-vehicle ambient brightness is lower than the minimum preset brightness threshold, the driver's door light starts to fade in. The starting value of the second door light fading in can be any value between the driver's door light being completely off (0%) and completely on (100%). Optionally, the starting value of the second door light fading in can be the minimum preset brightness threshold or other values.

[0185] When the current in-vehicle ambient brightness is higher than the maximum preset brightness threshold, the driver's door light stops fading in, and the ending value of the second door light fading in is usually the door light being completely off (0%).

[0186] Among them, the fading-in time of the second door light can be set according to the difference between the minimum preset brightness threshold and the maximum preset brightness threshold. The greater the difference between the minimum preset brightness threshold and the maximum preset brightness threshold, the longer the fading-in time of the second door light.

[0187] It should be noted that the minimum preset brightness threshold and the maximum preset brightness threshold can be set according to user requirements.

[0188] The door light control method provided by the embodiment of the present application monitors the driver's door and the co-driver's door; when it is detected that the driver's door changes from the closed state to the open state, the current in-vehicle ambient brightness is obtained, ensuring the accuracy of the obtained current in-vehicle ambient brightness. Based on the current in-vehicle ambient brightness, determine the starting value, ending value, and fading-in time of the first door light corresponding to the driver's door, and generate driver's door light control information, ensuring the accuracy of the generated driver's door light control information. And / or when it is detected that the co-driver's door changes from the closed state to the open state, the current in-vehicle ambient brightness is obtained; based on the current in-vehicle ambient brightness, determine the co-driver's seat door light control information corresponding to the co-driver's door, ensuring the accuracy of the determined co-driver's seat door light control information corresponding to the co-driver's door.
