The battery BMS system is used to output a corresponding control signal to the projection lamp control module according to the monitored battery power to control the operation of the projection lamp.

BRIEF DESCRIPTION OF THE DRAWINGS

[0020] The following is a brief description of the contents expressed in the drawings of the present specification and the marks in the drawings:

[0021] Figure 1 The figure is a schematic diagram of the control system of the vehicle-mounted holographic projection lamp of the present invention. DETAILED DESCRIPTION

[0022] The specific implementation of the present invention will be further explained in detail below by describing the optimal embodiment with reference to the accompanying drawings.

[0023] This solution installs the holographic projection lamp in the trunk or front trunk of the vehicle to realize the personalized projection needs of users, supports automatic projection when the trunk or front trunk is opened, automatic closing function when the trunk or front trunk is closed, and manual projection function according to user needs. At the same time, it can monitor the status of the vehicle during the working process of the projection lamp to automatically adjust and close the projection lamp to meet the user's personalized projection lamp needs. The specific solution is as follows:

[0024] like Figure 1 As shown, a control system of a vehicle-mounted holographic projection lamp of this embodiment includes a projection lamp, a projection lamp control module, and a vehicle BCM; the projection lamp is arranged in the front trunk or the rear trunk, and is used to automatically or manually control the operation of the projection lamp when the rear trunk or the front trunk is opened; the projection lamp is a 3D holographic projection lamp, which can project images, patterns, animations and other information;

[0025] The output end of the projection lamp control module is connected to the projection lamp to control the operation of the projection lamp; the projection lamp control module is connected to the vehicle BCM, and the projection lamp control module is linked to obtain the opening control state of the front trunk or the rear trunk in the vehicle BCM when controlling the operation of the projection lamp. Since the projection lamp is set in the front trunk or the rear trunk, and both the front trunk and the rear trunk are controlled by the vehicle BCM and can upload the opening and closing state of the trunk or the front trunk to the vehicle BCM, the vehicle BCM is linked with the projection lamp control module, so that the projection lamp can be automatically turned on when the trunk or the front trunk is opened and automatically turned off when it is closed.

[0026] In addition to automatically controlling the opening and closing of the projection lamp, this solution also provides a manual control method, so a human-computer interaction module is set up, and the human-computer interaction module is connected to the projection lamp control module. The human-computer interaction module is used to input the user's control signal to control the projection work, that is, the user can manually turn on or off the projection lamp according to the manual control signal. Of course, since the projection lamp is set in the front and rear trunks, when it is manually turned on, the projection lamp control module will link the vehicle BCM to control the corresponding trunk or front trunk of the vehicle to open. Similarly, when the projection lamp is manually turned off, it will also link the vehicle BCM to control the closing of the front and rear trunks. In this solution, both the front and rear trunks adopt the electric control mode, so as to meet the linkage control requirements when controlling the projection lamp.

[0027] The human-computer interaction module is used to interact with the user. Therefore, in order to save costs, the human-computer interaction module can be reused or integrated into the vehicle-mounted central control. The human-computer interaction module is connected to the vehicle-mounted central control screen and is used to input the user's control signals based on the vehicle-mounted central control screen. The central control touch screen is used as the human-computer interaction interface, and the central control host is used as the core of data processing and control, so that the user can control and input the user's control signals through the central control touch screen.

[0028] Since the projection effect of a 3D projection lamp can be varied, such as images, lines, or short videos, the projection lamp control module is connected to a memory, and the memory is pre-set with configuration parameters of the content projected by the projection lamp. The projection content of the configuration parameters pre-stored in the memory can be set by the user as needed, and it can be connected to the user's external storage device through the central control host, and the projection content such as the projected image and short video is read by the central control host and then transferred to the memory for storage, thereby achieving the purpose of configurable and modifiable projection content of the projection lamp.

[0029] In this embodiment, the projection light control module is connected to the vehicle state detection module, and the projection light control module controls whether the projection light currently responds to the user's control signal according to the state of the vehicle detected by the vehicle state detection module. The vehicle state detection module includes but is not limited to a vehicle speed detection module, a vehicle lock detection module, etc. Taking the vehicle speed detection module as an example, it is used to monitor the vehicle speed. The projection light is only allowed to light up when the vehicle speed is 0 and the vehicle speed is not 0, indicating that the vehicle is driving. During driving, the 3D projection light is prohibited from working to avoid interference and influence of the projection content on the user's driving and avoid safety hazards.

[0030] In a preferred embodiment, the power supply end of the projection lamp is connected to the battery of the vehicle, and the input end of the projection lamp control module is connected to the battery BMS system. The battery BMS system is used to output a corresponding control signal to the projection lamp control module according to the monitored battery power to control the operation of the projection lamp. After the projection lamp is turned on, a communication connection is established between the projection lamp control module and the battery management system BMS. The BMS system monitors the SOC value of the vehicle battery in real time. When the SOC value is lower than the set threshold, it means that the power consumption of the projection lamp may affect the normal function of the vehicle, so it is necessary to prohibit the operation of the projection lamp. Therefore, the BMS outputs a prohibition instruction to the projection lamp control module after the SOC power is lower than the set threshold. After receiving the prohibition instruction from the BMS, the projection lamp control module controls the projection lamp to disconnect the power supply and stop working, thereby avoiding the influence of the vehicle entertainment device on the vehicle driving.

[0031] With respect to the control system of a vehicle-mounted holographic projection lamp provided in the above embodiment, this embodiment provides a control method of the holographic projection lamp control system of the above embodiment, and the control method includes:

[0032] To turn on the manual and automatic control modes of the projector lamp:

[0033] Manual mode: In manual mode, the user sends the command to turn on the projection lamp to the projection lamp control module, which interacts with the normal BCM to control the opening state of the trunk or front trunk to meet the working state of the projection lamp. After reaching the working state of the projection lamp, the projection lamp control module outputs a drive control signal to control the operation of the projection lamp; after receiving the opening command sent by the user through the central control touch screen, the projection lamp control module determines the current opening state of the front or rear trunk based on the interaction with the BCM. If it is in the opening state, it directly controls the projection lamp to start working. If it is not turned on, the trunk is opened through the BCM and then the projection lamp is turned on. When turning off, if the user enters the closing command through the central control touch screen, the projection lamp control module controls the closing of the projection lamp. At this time, the projection lamp control module does not control the opening state of the trunk, and its opening state is controlled by the user according to needs. In manual mode, the user enters the command signal to turn on or off the projection through the central control screen and sends the signal to the projection line control module through the CAN network or signal line.

[0034] In the automatic control mode, the projection light control module controls the on and off state of the projection light according to the open state of the trunk or front trunk sent by the vehicle BCM. When the trunk changes from closed to open through BCM, the projection light is controlled to turn on synchronously when the trunk is opened, and when the trunk is closed, the projection light is controlled to turn off synchronously, so as to achieve the purpose of dynamic following on and off.

[0035] The projector lamp control module controls the operation of the projector lamp by reading the projection content pre-configured in the memory, wherein the projection content configured in the memory is modified or adjusted by the user. The memory is pre-set with configuration parameters of the content projected by the projector lamp. The projection content of the configuration parameters pre-stored in the memory can be set by the user as needed, and it can be connected to the user's external storage device through the central control host, and the projection content such as the projection image and small video is read by the central control host and then transferred to the memory for storage, thereby completing the purpose of configurable and modifiable projection content of the projector lamp.

[0036] When the projection lamp control module controls the operation of the projection lamp, the vehicle status is monitored in real time, and the projection lamp is automatically turned off according to the vehicle status. During the operation of the projection lamp, if the vehicle status does not allow the projection lamp to work, the projection lamp is automatically controlled to be turned off, and the reason for automatically turning off the projection lamp is displayed through the human-computer interaction module, thereby avoiding the defect that the operation of the projection lamp affects the normal driving needs of the vehicle.

[0037] If the vehicle status includes the speed status, the projection light is only allowed to light up when the vehicle is stationary at a speed of 0. When the vehicle speed is not 0, it means that the vehicle is moving. During driving, the 3D projection light is prohibited to avoid interference and influence of the projection content on the user's driving and avoid safety hazards.

[0038] After the projection lamp is turned on, a communication connection is established between the projection lamp control module and the battery management system BMS. The BMS system monitors the SOC value of the vehicle battery in real time. When the SOC value is lower than the set threshold, it means that the power consumption of the projection lamp may affect the normal function of the entire vehicle. Therefore, the projection lamp needs to be prohibited from working. Therefore, when the SOC power is lower than the set threshold, the BMS outputs a prohibition instruction to the projection lamp control module. After receiving the prohibition instruction from the BMS, the projection lamp control module controls the projection lamp to disconnect the power supply and stop working, thereby avoiding the influence of the on-board entertainment devices on the vehicle driving.

[0039] In this embodiment, the holographic projection lamp can be used by customers to independently choose to project zodiac signs, totems, water scenery, short videos, etc. It not only provides lighting during display, but also can be personalized, allowing drivers and passengers to appreciate the projected images or videos from different angles, etc., which can better attract customers' desire to buy cars. Holographic projection trunks are also very meaningful for personalized customization. It can bring a dazzling visual experience, while highlighting a large number of subtle elements such as lines and colors. This technology is very creative. This solution outputs signals through the vehicle BCM, through the signal line to the lamp software control part, and the identification signal is output to the lamp hardware department to execute commands. The lamp can be assembled with the front and rear trunks. After adding the 3D holographic projection lamp, the vehicle starts to illuminate and project videos or pictures when the trunk is opened. It can also be assembled with car lights as atmosphere lights or projection lights to meet users' needs for interior lighting.

[0040] Obviously, the specific implementation of the present invention is not limited to the above-mentioned methods. As long as various non-substantial improvements are made using the method concept and technical solution of the present invention, they are all within the protection scope of the present invention.
