[0011] In some embodiments, the method further comprises: In the process of controlling the vehicle lights to be gradually turned off, in response to obtaining a light-off signal again, the vehicle lights are continuously controlled to be gradually turned off until the vehicle lights are completely turned off.

[0021] It should be understood that the specific embodiments described herein are only used to explain the technical solutions of the present application and are not used to limit the present application.
[0022] In order to better understand the technical solution of the present application, a detailed description will be given below in conjunction with the accompanying drawings and specific implementation methods.
[0023] The main solution of the embodiment of the present application is: in response to obtaining a light-off signal through the controller local area network bus, obtaining the current operating status of the vehicle; when the vehicle is currently in a driving state, controlling the lights to gradually turn off according to a preset light-off curve, and continuously obtaining the vehicle's light control signal through the controller local area network bus; in the process of controlling the lights to gradually turn off, in response to obtaining a light-on signal, restoring the lights to a fully lit state.
[0024] In the related technology, when a vehicle is driving at night, the headlights are an important factor in ensuring the life safety of the driver and passengers. At present, most headlights transmit signals through the controller area network CAN, but due to the risk of tampering with CAN, when the CAN signal is tampered with, the headlights will be abnormally extinguished, which brings extremely high safety risks to users when driving at night. Therefore, many vehicle manufacturers often use MAC authentication or control the low beam lights through hard wires alone to avoid tampering.
[0025] However, both MAC authentication and separate transmission of control signals via hard wires will incur inevitable additional costs.
[0026] In summary, how to ensure the safe control of car lights on the basis of cost saving is a problem that needs to be solved urgently.
[0027] Based on this, the present application provides a solution that enables safe control of vehicle lights without the need to add additional hardware facilities, saving additional costs.
[0028] It should be noted that the execution subject of this embodiment can be a computing service device with data processing, network communication and program running functions, such as a tablet computer, a personal computer, a mobile phone, etc., or a headlight control device capable of realizing the above functions, etc. The following takes the headlight control device as an example to illustrate this embodiment and the following embodiments.
[0029] Reference Figure 1 , Figure 1 The flowchart of the vehicle light control method provided by an embodiment of the present application is shown. The vehicle light control method can be applied to a vehicle light control device, and includes the following steps S110 to S130: Step S110, in response to obtaining the light-off signal, obtaining the current operating state of the vehicle.
[0030] The vehicle consists of multiple domain controllers, each of which includes multiple Electronic Control Units (ECUs). ECUs can send and receive data through the CAN bus, and the vehicle's central domain controller (corresponding to the central control terminal, such as the central control display) generally controls the components of the vehicle body. When executing control, the ECU in the central domain controller generally generates a control signal and periodically sends it to the CAN bus; the target ECU corresponding to the control signal can periodically receive the control signal through the CAN bus, thereby parsing the control signal and performing the corresponding action.
[0031] In this embodiment, if Figure 2 As shown, the body ECU and the ECU corresponding to the headlight are connected via a CAN twisted pair (i.e., the bus described below). The body ECU here refers to the ECU in the central domain controller. The body ECU can send the headlight control signal and other vehicle signals (such as ignition signal, speed signal, etc.) to the headlight ECU via the CAN bus, so that the headlight ECU executes the headlight control method provided in this embodiment according to the received data.
[0032] The headlight control signal may include a light-on signal and a light-off signal. It is understandable that the headlights of a vehicle generally have only two working states: on and off, that is, the light-on signal is used to adjust the vehicle to a fully lit state, and the light-off signal is used to adjust the headlights to a fully off state.
[0033] Since car lights are generally used at night and for lighting during driving, it is necessary to ensure that the lights remain on during driving, unless the driver turns them off manually. When the lights are turned off, whether they light up abnormally or not will not affect the driving safety of the vehicle.
[0034] In some embodiments, the light-off signal may be a tampered signal or a signal generated by manual control of the user. For the headlight, whether it is a tampered signal or a normal signal, there is no difference in the nature of the signal, and both will be recognized and executed normally by the headlight ECU.
[0035] Therefore, in this embodiment, when the light-off signal is obtained, it is first determined whether the vehicle is driving. Specifically, in some embodiments, the body ECU can send the vehicle's ignition (IG) signal to the headlight ECU. The headlight ECU can determine whether the vehicle is currently driving based on the IG signal.
[0036] Specifically, after obtaining the vehicle's ignition signal through the controller area network bus, if the ignition signal is on, it can be determined that the vehicle is currently in a driving state, that is, the vehicle is driving; when the ignition signal is off, it is determined that the vehicle is currently in a stationary state, that is, the vehicle is not driving.
[0037] It is understandable that only when the vehicle's ignition signal is START, the vehicle's engine will generate power, that is, the vehicle is in motion; when the vehicle's ignition signal is ON, only the vehicle's electrical system is in working condition, so that various devices and systems in the vehicle can work normally, such as lights, air conditioning, audio, etc.; when the ignition signal is in the ON state, it can be further switched to START to complete ignition, starting and other operations. When the vehicle's ignition signal is OFF, it means that the vehicle's main equipment and systems are not in working condition. That is, in the ON and OFF states, the ignition signal is turned off and the vehicle is stationary; in the START state, the ignition signal is started and the vehicle is in motion.
[0038] In some embodiments, when the vehicle is currently stationary, in response to obtaining a light-off signal through the CAN bus, the lights can be directly controlled to be completely turned off. It is understandable that when the vehicle is not in a driving state, even if the lights are abnormally turned off, it will not affect the safety of the vehicle, so the lights can be directly turned off.
[0039] It is understandable that if the headlights are abnormally turned off when they should be turned on, the driver and passengers can take the initiative to inspect and repair the vehicle to find out the cause of the abnormal headlight control and correct it in time.
[0040] Step S120, when the vehicle is currently in a driving state, the vehicle lights are controlled to be gradually turned off according to a preset light-off curve, and the vehicle light control signal is continuously obtained.
[0041] Step S130, in the process of controlling the vehicle lights to gradually turn off, in response to obtaining a light-on signal, restoring the vehicle lights to a fully lit state.
[0042] Among them, the preset light-off curve is a curve of changes between the brightness of the light source and time. Specifically, when the lights are controlled to be turned off, in order to achieve a more natural transition, the lights can be set to gradually turn off from a fully lit state, rather than directly turning off. It is understandable that the lights generally have a pulse width modulation (PWM) function. Through PWM dimming, the brightness of the LED in the lights can be adjusted, thereby controlling the brightness of the lights to gradually decrease over time until they are completely turned off.
[0043] In some embodiments, when the brightness of the light source is at a maximum value, the headlight is fully lit, and when the brightness of the light source is 0, the headlight is completely extinguished. Figure 3 As shown, the preset light-off curve can be preset as Figure 3 The curve in .
[0044] As mentioned above, after obtaining the light-off signal, the headlight ECU cannot determine whether the light-off signal is generated normally or maliciously tampered with. Therefore, to ensure safe driving, in this embodiment, the headlight ECU controls the headlight brightness to gradually decrease according to the preset light-off curve, while continuously obtaining new headlight control signals through the CAN bus to distinguish the legitimacy of the first light-off signal obtained.
[0045] Specifically, in this embodiment, the time variation value of the preset light-off curve of the vehicle is preset to be greater than a transmission cycle of the vehicle light control signal on the controller area network bus.
[0046] The transmission cycle of the headlight control signal on the CAN bus can be configured in advance by setting the CAN bus protocol. The headlight control signal can be transmitted on the CAN bus in the form of a periodic message, and the transmission cycle of the periodic message can be preset. For example, in some exemplary embodiments, the transmission cycle can be set to 1000ms, that is, it is sent every 1000ms.
[0047] When the driver or passenger manually turns on the vehicle's lights, the message containing the light-on signal is sent according to the above-mentioned sending cycle; the light ECU can parse the light-on signal from the received message once every sending cycle.
[0048] Based on this, the present embodiment is designed to make the time variation value of the preset light-off curve (i.e. Figure 3 The time interval from time 0 to time a in the above formula is greater than the transmission cycle of the vehicle light control signal. Figure 4 As shown in the figure, through such a design, if the light-off signal is maliciously tampered with, the light ECU will receive the light-on signal again when the lights are not completely off. At this time, it can be judged that the light-off signal obtained last time is illegal, so the lights are restored to a fully lit state, avoiding driving risks caused by abnormal light off.
[0049] In addition, in the process of controlling the car lights to gradually turn off, if the light-off signal is obtained again through the controller LAN bus, it means that the light-off signal obtained last time was not maliciously tampered with, that is, the car lights are allowed to continue to be controlled to gradually turn off until the lights are completely turned off.
[0050] The present embodiment provides a method for controlling vehicle lights. When a light-off signal is obtained and the vehicle is in driving state, the vehicle lights are controlled to be gradually turned off according to a preset light-off curve, and the legitimacy of the obtained light-off signal is judged based on the vehicle light control signal on the bus. When a light-on signal is obtained before the vehicle lights are completely turned off, it is determined that the obtained light-off signal is illegal, and the vehicle lights are controlled to be fully lit again, thereby ensuring that the vehicle lights will not be completely turned off due to maliciously tampered signals during driving, so that the safety of the driver and passengers can be guaranteed during driving.
[0051] This application also provides a vehicle light control device, please refer to Figure 5 , the vehicle light control device 100 comprises: The signal response module 110 is used to obtain the current running state of the vehicle in response to obtaining the light-off signal; The vehicle light control module 120 is used to control the vehicle lights to gradually turn off according to a preset light-off curve when the vehicle is currently in a driving state, and continuously obtain the vehicle light control signal, wherein the vehicle light control signal includes a light-off signal and a light-on signal, and the vehicle light control signal is a periodic signal; The safety recovery module 130 is used to restore the vehicle lights to a fully lit state in response to obtaining a light-on signal during the process of controlling the vehicle lights to gradually turn off.
