Description

Technical Field

[0001] This invention relates to the field of vehicle lighting control technology, and more specifically, to a vehicle lighting interaction system. Background Technology

[0002] Traditional automotive lighting is controlled by switches and relays. The body controller collects the voltage signal input by the driver through the switch, and then drives the corresponding relay according to the switch function to close the power circuit and light up the corresponding lamp.

[0003] Currently, depending on the different functions of the lights, a large number of power supply hardwire connections are required, resulting in a high electrical circuit failure rate. Furthermore, it requires the addition of more fuses and relays with different functions, increasing the weight and cost of the vehicle and limiting the expansion of the lights' functions.

[0004] Therefore, how to provide an in-vehicle lighting interaction system has become a technical problem that urgently needs to be solved in this field. Summary of the Invention

[0005] The purpose of this invention is to provide a new technical solution for an in-vehicle lighting interaction system.

[0006] According to a first aspect of the present invention, an in-vehicle lighting interaction system is provided, comprising: a domain control device, a lighting device, a battery pack, a power relay, and a control device;

[0007] The domain controller includes a first controller, a first signal acquisition module, and a first communication module. The first controller is electrically connected to the first signal acquisition module, the first communication module, the battery pack, the power relay, and the car horn. The first communication module is used to acquire physical switch signals and sensor signals of the vehicle. The first controller is connected to the battery pack and the power relay.

[0008] The control device includes a second controller, a second signal acquisition module, a second communication module, and a diagnostic module. The second controller is electrically connected to the second signal acquisition module, the second communication module, the diagnostic module, and the lighting device, respectively. The second controller is also connected to the power relay.

[0009] Both the diagnostic module and the second communication module are communicatively connected to the first communication module. The second communication module is used to receive vehicle operation information transmitted by the first communication module, so that the second controller can control the lighting device to perform corresponding operations. The diagnostic module monitors the operation information of the lighting device in real time and generates diagnostic information.

[0010] Optionally, the information collected by the second communication module includes light signal information, high beam information, low beam information, position light information, turn signal information, and daytime running light information.

[0011] Optionally, the first communication module is connected to the vehicle network channel. When the lighting device malfunctions, the diagnostic module sends diagnostic information to the first communication module, which then transmits the diagnostic information to the vehicle network channel so that the vehicle's instrument panel / MP5 displays the corresponding fault.

[0012] Optionally, the control device further includes an identification module, which is electrically connected to the second signal acquisition module. The identification module is used to identify the user's action information and convert the action information into control signals.

[0013] When a user forgets to turn off the vehicle power and is about to leave the vehicle, and the domain control device is not properly powered down, the identification module identifies the user's action information and converts the action information into a control signal, which is then sent to the second signal acquisition module to control the domain control device to power down.

[0014] Optionally, the identification module can be radar, camera, or any combination of the two.

[0015] Optionally, the lighting device includes a headlight and a rear combination lamp.

[0016] Optionally, the domain controller further includes a first voltage regulator module, which is connected to the first controller, the battery pack, and the power relay.

[0017] Optionally, the control device further includes a second voltage regulator module, which is connected to the second controller, the power relay, and the lighting device.

[0018] Optionally, the control device further includes a gear switch module and an adjustment motor, wherein the gear switch module is connected to the adjustment motor, and the adjustment motor is connected to the lighting device for adjusting the gear of the lighting device.

[0019] The beneficial effects of this invention are as follows:

[0020] This invention employs a distributed control architecture combining domain control devices and control devices, replacing traditional hard-wired connections with communication signal transmission, effectively addressing many shortcomings of traditional vehicle lighting control methods. Compared to the traditional switch-and-relay control mode, this system significantly reduces the number of hard-wired power supplies for the lights, simplifies the overall vehicle electrical wiring structure, reduces the incidence of short circuits and poor contact, and improves the reliability of the electrical system. Simultaneously, it reduces the use of numerous relays and fuses, lowering vehicle weight and component costs, and optimizing assembly processes.

[0021] The control device of this invention receives vehicle operation information from the domain control device through the first communication module, enabling precise driving and coordinated control of the lighting device, ensuring timely lighting response and stable control. The diagnostic module monitors the operating status of the lighting device in real time and generates diagnostic information, enabling rapid fault location and proactive reporting, facilitating later maintenance. The overall architecture adopts a modular design, allowing for lighting function expansion and software upgrades without hardware modifications, breaking through the limitations of traditional hard-wired control on function expansion, and improving the intelligence level and scalability of the entire vehicle's electrical system.

[0030] like Figure 1As shown, this embodiment of the invention provides an in-vehicle lighting interaction system, including: a domain control device 1, a lighting device 2, a battery pack 3, a power relay 4, and a control device 5.

[0031] The domain controller includes a first controller 11, a first signal acquisition module 12, and a first communication module 13. The first controller 11 is electrically connected to the first signal acquisition module 12, the first communication module 13, the battery pack 3, the power relay 4, and the car horn. The first communication module 13 is used to acquire the vehicle's physical switch signals and sensor signals. The first controller 11 is connected to the battery pack 3 and the power relay 4.

[0032] The control device 5 includes a second controller 51, a second signal acquisition module 52, a second communication module 53, and a diagnostic module 54. The second controller 51 is electrically connected to the second signal acquisition module 52, the second communication module 53, the diagnostic module 54, and the lighting device 2, respectively. The second controller 51 is also connected to the power relay 4.

[0033] Specifically, the lighting device 2 includes a headlight and a rear combination lamp.

[0034] Both the diagnostic module 54 and the second communication module 53 are communicatively connected to the first communication module 13. The second communication module 53 is used to receive vehicle operation information transmitted by the first communication module 13 so that the second controller 51 can control the lighting device 2 to perform corresponding operations. The diagnostic module 54 monitors the operation information of the lighting device 2 in real time and generates diagnostic information.

[0035] Specifically, when the vehicle is powered on, the battery pack 3 provides operating power to the domain control device 1, and the first controller 11 in the domain control device 1 enters the working state. The first signal acquisition module 12 acquires the vehicle power-on signal and transmits it to the first controller 11. After receiving the power-on command, the first controller 11 outputs a control signal to close the power relay 4, providing operating power to the control device 5 and the lighting device 2.

[0036] Simultaneously, the first communication module 13 collects vehicle physical switch signals, sensor signals, and preset light commands, and sends the aforementioned vehicle operation information to the second communication module 53 of the control device 5. The second controller 51 obtains the signals transmitted by the second communication module 53 through the second signal acquisition module 52, and drives the lighting device 2 to perform power-on lighting actions according to preset control logic to achieve the preset lighting effect. During this process, the first controller 11 can simultaneously drive the car horn to perform the power-on prompt function, completing the vehicle power-on and lighting start-up control.

[0037] When the vehicle is powered off, the first signal acquisition module 12 transmits the power-off signal to the first controller 11. After receiving the power-off command, the first controller 11 sends the power-off information and related sensor signals to the second communication module 53 through the first communication module 13. The first controller 11 determines whether the delayed power-off condition is met based on the environmental parameters collected by the sensors. If the delay condition is met, the power relay 4 is disconnected with a delay, maintaining the power supply to the lighting device 2 for a short time.

[0038] The second controller 51 controls the lighting device 2 to perform the corresponding lighting function based on the received power-down and lighting control signals. During the vehicle power-down and delayed power-off process, the diagnostic module 54 monitors the operating status, voltage, current, and other operational information of the lighting device 2 in real time, and generates diagnostic information, which is fed back to the first controller 11 through the first communication module 13, realizing real-time monitoring of the lighting status during the power-down process. When the delay time ends, the first controller 11 controls the power relay 4 to disconnect, and the control device 5 and the lighting device 2 are powered off, completing the vehicle power-down process.

[0039] This invention employs a distributed control architecture combining domain control device 1 and control device 5, replacing traditional hard-wired connections with communication signal transmission, effectively addressing many shortcomings of traditional vehicle lighting control methods. Compared to the traditional switch-and-relay control mode, this system significantly reduces the number of hard-wired power supplies for the lighting fixtures, simplifies the overall vehicle electrical wiring structure, reduces the incidence of short circuits and poor contact, and improves the reliability of the electrical system. Simultaneously, it reduces the use of numerous relays and fuses, lowering vehicle weight and component costs, and optimizing assembly processes.

[0040] The control device 5 of this invention receives vehicle operation information from the domain control device 1 via the first communication module 13, enabling precise driving and coordinated control of the lighting device 2, ensuring timely lighting response and stable control. The diagnostic module 54 monitors the lighting device's operating status in real time and generates diagnostic information, enabling rapid fault location and proactive reporting, facilitating future maintenance. The overall architecture adopts a modular design, allowing for lighting function expansion and software upgrades without hardware modifications, breaking through the limitations of traditional hard-wired control on function expansion, and improving the intelligence and scalability of the entire vehicle's electrical system.

[0041] In one embodiment of the vehicle lighting interaction system of the present invention, the information collected by the second communication module 53 includes light signal information, high beam information, low beam information, position light information, turn signal information, and daytime running light information.

[0042] Specifically, the second communication module 53 integrates the collection of light signals, high beam, low beam, position lights, turn signals, and daytime running lights. It can uniformly receive and transmit various lighting control commands, reducing the number of signal hardwires and wiring complexity, lowering the probability of electrical faults, eliminating multiple sets of relays and fuses, and reducing the weight and cost of the entire vehicle. At the same time, it realizes centralized management and coordinated control of lighting signals, improves the response speed and control accuracy of the lights, facilitates the expansion and upgrading of intelligent lighting functions such as light signals, and works with the diagnostic module 54 to realize real-time monitoring of all lighting functions, improving system reliability and maintenance convenience.

[0043] In one embodiment of the vehicle lighting interaction system of the present invention, the first communication module 13 is connected to the vehicle network channel. When the lighting device 2 malfunctions, the diagnostic module 54 sends diagnostic information to the first communication module 13, and the first communication module 13 transmits the diagnostic information to the vehicle network channel so that the vehicle's instrument panel / MP5 displays the corresponding fault.

[0044] Specifically, the first communication module 13 is connected to the vehicle network channel. When the lighting device 2 malfunctions, the diagnostic module 54 can upload the diagnostic information to the vehicle network channel through the first communication module 13, so that the vehicle instrument panel and MP5 can display the corresponding fault prompts in real time. There is no need to add additional fault indicator lights and hard wiring, simplifying electrical wiring and reducing costs and failure rates. At the same time, it realizes the sharing and visualization of lighting fault information throughout the vehicle, making it easy for the driver to know the abnormal status of the lighting in a timely manner, improving driving safety and fault diagnosis efficiency, and enhancing the intelligence and integration of the vehicle's electrical system.

[0045] In one embodiment of the vehicle lighting interaction system of the present invention, the control device 5 further includes an identification module 55, which is electrically connected to the second signal acquisition module 52. The identification module 55 is used to identify the user's action information and convert the action information into a control signal.

[0046] When a user forgets to turn off the vehicle power and is about to leave the vehicle, and the domain control device 1 is not normally powered down, the identification module 55 identifies the user's action information and converts the action information into a control signal, which is sent to the second signal acquisition module 52 to control the domain control device 1 to power down.

[0047] The identification module 55 of this invention can identify the user's action information when leaving the vehicle and convert it into a control signal. When the user forgets to turn off the vehicle power or the domain control device 1 is not properly powered down, it can automatically trigger power-off control, preventing battery depletion due to prolonged power-on and improving vehicle safety and convenience. This setting achieves intelligent power-off without manual operation, reducing the risk of malfunctions caused by human negligence, further optimizing the vehicle's electrical control logic, and improving the intelligence and automation level of the vehicle lighting interaction system.

[0048] In one embodiment of the vehicle lighting interaction system of the present invention, the identification module is radar, camera, or any combination of the two.

[0049] The radar and camera built into the rear combination lights collect real-time data on the environment behind and around the vehicle, and transmit the collected radar data and camera data to the second controller 51. The second controller 51 uploads the environmental data to the first controller 11 of the domain control device 1 via the second communication module 53, the first communication module 13, the vehicle communication bus, or an Ethernet cable. The first controller 11 processes, calculates, and judges the data according to preset logic, and transmits the processing results to the vehicle instrument panel, MP5 player, or vehicle terminal TBOX via the first communication module 13 through the vehicle network channel, realizing assisted driving prompts or remote monitoring functions, reminding the driver of real-time road conditions and vehicle status.

[0050] When the driver forgets to turn off the vehicle's power and prepares to leave the vehicle, leaving the domain control device 1 in a state of not being properly powered off, the radar in the rear combination lights monitors the driver's position changes and movements away from the vehicle in real time, and transmits the position change data to the second controller 51. The second controller 51 then transmits the vehicle departure signal to the first controller 11 via the second communication module 53 and the first communication module 13. After the first controller 11 determines that the condition of leaving the vehicle without powering off is met, it activates the car horn to sound a warning, reminding the driver that the vehicle is not properly powered off and preventing battery depletion.

[0051] In one embodiment of the vehicle lighting interaction system of the present invention, the domain controller further includes a first voltage regulator module 14, which is connected to the first controller 11, the battery pack 3, and the power relay 4.

[0052] Specifically, the first voltage regulator module 14 can stabilize the input voltage of the battery pack 3, providing a stable and reliable operating voltage for the first controller 11 and key system components, avoiding voltage fluctuations and spike interference during vehicle power-on, power-off, and load switching, and improving the operational stability and anti-interference capability of the domain controller; at the same time, it plays a role in voltage adaptation and protection for the power relay 4 and subsequent circuits, reducing the risk of component damage caused by abnormal voltage, and improving the reliability and service life of the entire vehicle lighting interaction system.

[0053] Furthermore, the control device 5 also includes a second voltage regulator module 56, which is connected to the second controller 51, the power relay 4, and the lighting device 2.

[0054] Specifically, the second voltage regulator module 56 can regulate, filter, and adapt the voltage output by the power relay 4, providing a stable and clean power supply to the second controller 51 and the lighting device 2. It suppresses voltage fluctuations and interference generated by the vehicle's electrical system during start-up, shutdown, and load switching, preventing the lights from flickering, having uneven brightness, or malfunctioning, and ensuring accurate and reliable lighting control. At the same time, it provides overvoltage and undervoltage protection for the second controller 51 and the lighting device 2, reducing the probability of component damage and improving the system's operational stability, anti-interference ability, and service life.

[0055] In one embodiment of the vehicle lighting interaction system of the present invention, the control device 5 further includes a gear switch module 6 and an adjustment motor 7. The gear switch module 6 is connected to the adjustment motor 7, and the adjustment motor 7 is connected to the lighting device 2 for adjusting the gear of the lighting device 2.

[0056] The gear switch module 6 of this invention, in conjunction with the adjustment motor 7, enables automatic / manual adjustment of the gear position of the lighting device 2. It can precisely adjust the working state and illumination angle of the lighting device according to driving scenarios and load changes, thereby improving lighting adaptability and driving safety. The modular electronic control adjustment eliminates the need for traditional mechanical adjustment structures, simplifies assembly, improves adjustment accuracy and response speed, and enhances reliability and service life. At the same time, it facilitates linkage with the control system to achieve intelligent control of the lighting gear position, expands the functional scenarios of the lighting device, and further improves the integration and intelligence level of the vehicle lighting interaction system.
