[0033] In order to make the technical problems, technical solutions and beneficial technical effects to be solved by the present application clearer, the present application will be further described in detail below in conjunction with the accompanying drawings and multiple exemplary embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application, rather than to limit the scope of protection of the present application.

[0034] Figure 1 The flowchart of the method for controlling the vehicle-mounted lighting device according to an exemplary embodiment of the present application is shown. The following exemplary embodiments describe the method according to the present application in more detail.

[0035] The method according to the present application is applicable to a vehicle 1 having an on-board lighting device 11, and the on-board lighting device 11 can be controlled based on the operating conditions of the vehicle, for example, including a turn indicator light, a brake indicator light, an adaptive high beam, a low beam, a reversing light and / or a parking light, etc. According to the prior art, it is necessary to control the vehicle to travel at a set driving speed and / or driving direction in different road test scenarios, and to test and / or calibrate the on-board lighting device based on the response state of the on-board lighting device at the set driving speed and / or driving direction of the vehicle, which increases the cost of testing and / or calibrating the on-board lighting device, especially when the vehicle is driving at high speed, which also brings greater safety hazards. The method according to the present application can realize the testing and / or calibration of the on-board lighting device 11 when the vehicle remains stationary.

[0036] like Figure 1 As shown, the method may include steps S1 and S2. In step S1, in response to parameter configuration information input by an operator, vehicle key information and operator identity information may be acquired and verified. Figure 2The schematic diagram of a vehicle 1 and a cloud server 3 according to an exemplary embodiment of the present application is shown. The parameter configuration information input by the operator can be obtained through the vehicle touch screen 12 of the vehicle 1. The parameter configuration information may include vehicle control information and / or driving environment information, which is used to configure the vehicle's operating conditions and / or driving environment. Exemplarily, the vehicle control information may include not only vehicle speed control information (such as accelerator pedal angle information, gear information, expected vehicle speed information, etc.), which is used to configure the vehicle's driving speed, but also steering wheel deflection angle control information, which is used to configure the vehicle's driving direction. The driving environment information may include, for example, position information, size information, and speed information of target objects (such as surrounding vehicles, pedestrians, obstacles, etc.) in the driving environment, and various road test scenarios can be simulated based on this information. In addition, considering that the control of vehicle-mounted lighting devices such as adaptive high beams and low beams is also related to weather information and / or ambient lighting information, the driving environment information may also include weather information (such as visibility and / or rainfall, etc.) and / or ambient lighting information.

[0037] In order to prevent unauthorized operators from configuring parameters of the vehicle and to prevent parameter configuration information input by the operator from being tampered with, the identity information of the operator (such as the personal identification code of the operator) can be obtained through the vehicle touch screen 12 of the vehicle 1, and the vehicle key information can be obtained from the vehicle controller 13 of the vehicle 1. After the communication connection between the cloud server 2 and the vehicle controller 13 is established, the vehicle key information and the identity information of the operator can be verified through data interaction between the cloud server 2 and the vehicle controller 13.

[0038] The verification method may include, for example, account and password verification, where the operator operates a vehicle key compatible with the vehicle 1 and enters an account and password, and then verifies the acquired vehicle key information and the account and password entered by the operator through the vehicle key information and account and password information stored in the cloud server 2.

[0039] The verification method may also include biometric verification, such as facial recognition verification, fingerprint recognition verification, voice recognition verification, etc. The acquired vehicle key information and the biometric characteristics of the operator operating the vehicle key may be verified through the vehicle key information and biometric information stored in the cloud server 2.

[0040] The verification method may also include security token verification. The operator operates the adapted vehicle key and enters the account password. He also needs to enter the instructions obtained from the authorized security token. The obtained vehicle key information, account password and instructions are verified in the cloud server 2. Since the instructions are updated at regular intervals and the vehicle key information, account password and instructions must all match to complete the verification, data security is further improved through this verification method. Even if the operator's account password is stolen, the verification cannot be passed.

[0041] like Figure 3 A schematic diagram of a vehicle 1, an external device 3 and a cloud server 2 according to another exemplary embodiment of the present application is shown. The external device 3 and the vehicle controller 13 can be data connected, for example, through a data cable and an OBD interface. The external device 3 can be, for example, a tablet computer, a mobile terminal, a laptop computer, etc. Here, the parameter configuration information and the operator's identity information input by the operator can be obtained through the input unit of the external device 3 (such as a keyboard, a touch screen, an intelligent voice device, etc.). After establishing a communication connection between the cloud server 2, the external device 3 and the vehicle controller 13, the vehicle key information can be obtained from the vehicle controller 13 of the vehicle 1, and the vehicle key information and the operator's identity information can be verified through data interaction between the vehicle controller 13, the external device 3 and the cloud server 2. The verification method can also include account password verification, biometric verification and / or security token verification, etc.

[0042] In step S2, when the vehicle key information and the identity information of the operator are verified, a simulation signal about the vehicle operating condition can be generated based on the parameter configuration information input by the operator, and the vehicle-mounted lighting device can be controlled at least based on the generated simulation signal. In the static state of the vehicle 1, a simulation signal about the vehicle operating condition can be generated by the simulation signal generation module 103 based on the parameter configuration information, and the simulation signal especially includes a simulation signal about the vehicle driving speed and / or a simulation signal about the vehicle driving direction, thereby simulating the operating condition of the vehicle driving at a set speed and / or a set deflection angle in a set driving scene. Here, the simulation signal about the vehicle driving speed and / or the simulation signal about the vehicle driving direction can be directly generated based on the vehicle speed control information, such as the accelerator pedal angle information, the gear position information, the expected vehicle speed information, etc., and / or the steering wheel deflection angle control information, or the control instruction of the auxiliary driving system of the vehicle 1 can be generated based on the driving environment information, such as the position information, size information and speed information of the target object in the driving environment, and the simulation signal about the vehicle driving speed and / or the simulation signal about the vehicle driving direction can be generated based on the control instruction.

[0043] In the embodiment of the present application, the analog signal can replace the real signal about the vehicle operating condition detected by the vehicle sensor (such as the vehicle speed sensor and / or the steering angle sensor, etc.) to be input into the vehicle lighting control module 104 and participate in the control process of the vehicle lighting device 11. At the same time, considering that the control of the vehicle lighting devices such as the adaptive high beam and the low beam is also related to the weather information and / or the ambient light information, the configured driving environment information can also be additionally introduced as the control factor of the vehicle lighting device 11, that is, the vehicle lighting device 11 is controlled based on the generated analog signal and the driving environment information.

[0044] Exemplarily, if the analog signal about the vehicle's driving speed indicates that the vehicle speed reaches 40 km / h or more, and the configured ambient light intensity is lower than a certain light intensity threshold, and according to the configured target object information in the driving environment (including position information, size information, speed information, etc.), no light sources such as oncoming vehicles and vehicles in front are detected in front of the vehicle 1, then the adaptive high beam can be turned on, and the light intensity and light angle of the adaptive high beam can be adjusted based on the analog signal about the vehicle's driving speed and / or the analog signal about the vehicle's driving direction and the configured target object information in the driving environment, thereby completing the testing and / or calibration of the adaptive high beam.

[0045] For another example, when the analog signal regarding the vehicle's driving direction indicates that the vehicle 1 is turning at a certain deflection angle, the turn indicator light corresponding to the turning direction may be turned on, and the corresponding turn indicator light may be turned off after the analog signal regarding the vehicle's driving direction indicates that the vehicle 1 has completed the turning process, thereby completing the test and / or calibration of the turn indicator light.

[0046] For another example, when the operator inputs information about a pedestrian or obstacle within a predetermined distance in front of the vehicle 1 (including position information, size information and / or speed information), the auxiliary driving system of the vehicle 1 will generate a control instruction for the braking operation, so that the analog signal generated about the vehicle's driving speed indicates that the vehicle 1 needs to perform a braking operation, thereby turning on the brake indicator light, and turning off the brake indicator light and turning on the parking light after the analog signal about the vehicle's driving speed indicates that the vehicle 1 is completely stationary, thereby completing the testing and / or calibration of the brake indicator light and the parking light.

[0047] For another example, when the analog signal regarding the vehicle's driving direction indicates that the vehicle 1 is performing a reversing operation, the reversing lights may be turned on, and after the analog signal regarding the vehicle's driving speed indicates that the vehicle 1 is completely stationary, the reversing lights may be turned off and the parking lights may be turned on, thereby completing the testing and / or calibration of the reversing lights and the parking lights.

[0048] According to an embodiment of the present application, after the operator's identity information is verified, the operator can configure the vehicle's parameters while the vehicle remains stationary, thereby generating a simulation signal about the vehicle's operating condition. The simulation signal can replace the real detection signal of the on-board sensor to participate in the control of the on-board lighting device, thereby achieving testing and / or calibration of various on-board lighting devices by simulating different driving scenarios, thereby reducing the cost of testing and / or calibration of the on-board lighting device, and effectively avoiding the risks that may be caused by road testing, and can also prevent unauthorized operators from configuring the vehicle's parameters and prevent the parameter configuration information entered by the operator from being tampered with.

[0049] In addition, it should be noted that the step numbers described herein do not necessarily represent a chronological order, but are merely a figure mark. The order can be changed according to specific circumstances as long as the technical purpose of the present application can be achieved.

These software modules can be programmed in assembly language and compatible with other existing software modules in the vehicle controller 13. The operator can input parameter configuration information and the identity information of the operator through the vehicle touch screen 12 of the vehicle 1, and these input information can be obtained by the data input module 101 in the vehicle controller 13. In response to the input information, the identity authentication module 102 in the vehicle controller 13 establishes a communication connection with the cloud server 2, and completes the identity authentication of the operator through the data interaction between the identity authentication module 102 and the cloud server 2. After passing the identity authentication, the analog signal generation module 103 of the vehicle controller 13 can generate an analog signal about the vehicle operating condition, and the vehicle light control module 104 of the vehicle controller 13 can control the vehicle light device 11 based on the generated analog signal and optional driving environment information. The methods according to the present application are all executed in the vehicle controller 13 , thereby eliminating the need for additional external devices and data lines required to connect them to the vehicle controller 13 .

In the external device 3, the data input module 101, the identity authentication module 102 and the simulation signal generation module 103 can be compiled in a computer language such as C language, C++ language, JAVA language, etc.; the vehicle light control module 104 can especially be an existing software module in the vehicle controller 13, but the input signal of the vehicle light control module 104 is replaced by the real signal of the vehicle running condition detected by the vehicle sensor with the simulation signal generated by the simulation signal generation module 103. The operator can input parameter configuration information and operator identity information through the input unit (such as a keyboard, a touch screen, an intelligent voice device, etc.) of the external device 3. In response to the input information, the identity verification module 102 in the external device 3 can obtain the vehicle key information from the vehicle controller 13, and establish a communication connection with the cloud server 2, and complete the identity verification of the operator through data interaction between the identity verification module 102 and the cloud server 2. Then, a simulation signal about the vehicle operating condition can be generated in the simulation signal generation module 103 of the external device 3 based on the parameter configuration information input by the operator, and the generated simulation signal is transmitted to the vehicle lighting control module 104 of the vehicle controller 13, where the vehicle lighting device 11 is controlled based on the generated simulation signal and optional driving environment information.
