车身控制模块可以包括车辆的主控器，从而可以得到车辆信息。车辆信息可以包括车辆环境信息，如车辆行驶状态(如车辆行驶状态)、车辆与身份识别设备的位置关系等。其中，车辆身份识别设备可以为钥匙。车辆信息还可以包括车身组件信息，如车辆各功能组件的状态(如车灯的当前状态、车身悬挂高度、车门状态、刹车状态、电力供应状态等)。其中，车灯包括第一车灯和第二车灯。The body control module may include a main controller of the vehicle so that vehicle information can be obtained. The vehicle information may include vehicle environment information, such as vehicle driving status (eg, vehicle driving status), the positional relationship between the vehicle and the identification device, and the like. Wherein, the vehicle identification device may be a key. The vehicle information may also include vehicle body component information, such as the status of various functional components of the vehicle (eg, the current status of lights, vehicle suspension height, door status, brake status, power supply status, etc.). Wherein, the vehicle lamp includes a first vehicle lamp and a second vehicle lamp.
车身控制模块可以根据车辆信息，进行内部的逻辑判断后向第一车灯主控器发送第一控制命令，如判断是否满足灯光开启条件及灯光开启方式(如DLP投影灯投影或ISD灯显示或二者同时开启)。The body control module can send a first control command to the first lamp master controller after making internal logical judgments based on vehicle information, such as judging whether the lighting conditions and lighting switching methods (such as DLP projection lamp projection or ISD lamp display or Both are turned on at the same time).
也就是说，车身控制模块可以自动触发第一车灯工作。例如：根据车辆信息确定场景，并根据该场景生成对应的第一控制命令，进而发送给第一车灯主控器，第一车灯主控器根据第一车灯主控命令调用该场景对应的灯光显示配置文件，控制第一车灯工作。That is to say, the body control module can automatically trigger the first lamp to work. For example: determine the scene according to the vehicle information, and generate the corresponding first control command according to the scene, and then send it to the first headlight master controller, and the first headlight master controller calls the scene corresponding to the first headlight master control command according to the first headlight master control command. The light display profile, which controls the work of the first headlight.
在一个示例中，如图3所示，用户携带有身份识别设备，如钥匙。车身控制模块检测到存在本车的身份识别设备，从而建立与该身份识别设备的连接，进而可以检测身份识别设备与车辆的距离。车身控制模块根据该距离确定用户处于某一个场景区，如迎宾区，进而车身控制模块根据用户所处的场景区发送对应的第一控制命令给第一车灯主控器。另外，多媒体模块向车身控制模块发送多媒体数据，如车辆当前续航信息、天气信息、时间、节日、纪念日等。第一车灯主控器(外灯模块)收到多媒体数据和第一车灯主控器后，调用内部对应的灯光控制文件，生成第一车灯主控命令，发送给对应的投影灯控制器和ISD灯控制器，从而控制DLP投影灯、ISD灯等第一车灯(外灯)工作。进一步地， 第一车灯主控器(外灯模块)向车身控制模块返回第一车灯(外灯)的执行结果。In one example, as shown in Figure 3, the user carries an identification device, such as a key. The body control module detects the existence of the identification device of the vehicle, thereby establishing a connection with the identification device, and then detecting the distance between the identification device and the vehicle. The body control module determines that the user is in a certain scene area, such as a welcome area, according to the distance, and then the body control module sends a corresponding first control command to the first lamp master controller according to the scene area where the user is located. In addition, the multimedia module sends multimedia data to the body control module, such as current vehicle battery life information, weather information, time, festivals, anniversaries, and the like. After receiving the multimedia data and the first lamp master controller, the first lamp master controller (outer lamp module) calls the corresponding internal lighting control file, generates the first lamp master control command, and sends it to the corresponding projector lamp controller And ISD lamp controller, so as to control the first vehicle lamp (exterior lamp) such as DLP projector lamp and ISD lamp to work. Further, the first vehicle lamp master controller (exterior lamp module) returns the execution result of the first vehicle lamp (exterior lamp) to the body control module.
例如：DLP投影灯根据预设的灯光视频投影逻辑进行投影，如投影视频为依次播放品牌Logo、欢迎文字、天气、日期、节日。其中天气、日期、节日、纪念日信息会跟随多媒体模块发送的信息进行投影显示，ISD灯同样按照预设视频进行播放，与DLP投影进行同步显示。For example, the DLP projection lamp projects according to the preset lighting video projection logic. For example, the projection video is to play the brand logo, welcome text, weather, date, and festival in sequence. Among them, the weather, date, festival, and anniversary information will be projected and displayed along with the information sent by the multimedia module. The ISD light will also be played according to the preset video and displayed synchronously with the DLP projection.

多媒体模块还用于根据用户命令生成车灯设置数据，并通过中央网关向车身控制模块发送车灯设置数据；车身控制模块还用于根据车灯设置数据生成第一车灯主控命令。The multimedia module is also used to generate vehicle lamp setting data according to user commands, and send the vehicle lamp setting data to the body control module through the central gateway; the body control module is also used to generate the first vehicle lamp master control command according to the vehicle lamp setting data.
也就是说，多媒体模块和车身控制模块可以通过中央网关进行通讯。多媒体模块可以通过中央网关向车身控制模块发送第一车灯设置数据，如用户的车灯开关设置项。车身控制模块根据多媒体模块发送的第一车灯设置数据生成对应的第一控制命令，如用户的车灯开关设置项。第一车灯主控器根据该开关设置项以及车辆信息判断第一车灯是否执行灯光功能。That is, the multimedia module and the body control module can communicate via the central gateway. The multimedia module may send the first vehicle lamp setting data, such as the user's vehicle lamp switch setting item, to the body control module through the central gateway. The body control module generates a corresponding first control command according to the first lamp setting data sent by the multimedia module, such as a user's lamp switch setting item. The first vehicle lamp master controller determines whether the first vehicle lamp performs a lighting function according to the switch setting item and the vehicle information.

The network sends the light material to the first headlight master controller. The body control module determines whether the current vehicle information (such as vehicle speed, gear position, external environment, etc.) satisfies the projection turn-on conditions, and if so, sends the corresponding first control command (lighting control command) to the first lamp master controller (external lamp). module). The first headlight master controller (outer light module) adjusts the lighting material according to the user's instructions according to the first headlight setting data, generates a first headlight master control command and sends it to each first headlight sub-controller to trigger the corresponding The first headlight projection light material.
