[0035] To make the objectives, technical solutions, and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application. Apparently, the described embodiments are some, but not all, of the embodiments of the present application. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present application without creative efforts shall fall within the protection scope of the present application.

[0036] With the development of the vehicle industry, headlights not only perform the lighting function, but also are an important part of safety and aesthetics.

[0037] Currently, headlight systems usually adopt a fixed lighting irradiation mode, which to a certain extent restricts the improvement of the performance of headlight systems and the adaptability to different road lighting requirements, resulting in the inability to meet the lighting requirements of different roads.

[0038] Based on the above problems, the present application provides a matrix headlight control system, with the headlight driving chip as the core. By controlling the lighting of matrix headlights at different angles on the lamp board, diverse irradiation effects are achieved, which can better meet the lighting requirements of different roads and improve the adaptability and safety of vehicle lighting.

[0039] Figure 1Schematic diagram of a matrix headlight control system provided by an embodiment of the present application. As Figure 1 shown, the matrix headlight control system 100 of the embodiment of the present application includes: a control unit 101, a headlight driving chip 102, and a matrix manager 103.

[0040] Among them, the control unit 101 is electrically connected to the headlight driving chip 102 and the matrix manager 103 respectively;

[0041] The control unit 101 is configured to send a headlight driving signal to the headlight driving chip 102 and send a mode control signal to the matrix manager 103 according to the received target signal.

[0042] The headlight driving chip 102 is configured to provide current and voltage for the matrix headlights according to the headlight driving signal.

[0043] The matrix manager 103 is configured to control the lighting of matrix headlights at different angles on the lamp board according to the mode control signal.

[0044] In the embodiment of the present application, exemplarily, the control unit 101 receives a target signal from a vehicle body sensor, and according to the received target signal, sends a headlight driving signal to the headlight driving chip 102 and sends a mode control signal to the matrix manager 103 to intelligently adjust the light intensity and irradiation angle of matrix headlights at different angles on the lamp board. Among them, the vehicle body sensor can monitor various state parameters of the vehicle in real time and transmit the data to the control unit 101. The vehicle body sensor can include, for example, a vehicle body slope sensor, an acceleration sensor, and an ambient light sensor. For specific vehicle body sensors, reference can be made to subsequent embodiments. The control unit 101 is, for example, the ECU of the vehicle, or the Central Control Unit (CCU) of the vehicle.

[0045] After receiving the headlight driving signal sent by the control unit 101, the headlight driving chip 102 provides current and voltage for the matrix headlights according to the headlight driving signal to turn on, turn off, and adjust the brightness of the matrix headlights. Among them, the matrix headlights are composed of multiple independently controlled light-emitting diode (LED) lamp groups, which can achieve complex lighting effects; through the matrix headlights, the brightness and switch states of each LED lamp group can be dynamically adjusted according to the actual road conditions to provide the best lighting effect; through the matrix headlights, the oncoming vehicles can be automatically detected and the lighting intensity in the corresponding area can be reduced to avoid dazzling the drivers of other vehicles; through the matrix headlights, the high and low beams can be intelligently switched according to the vehicle speed and ambient light intensity to improve driving safety. Specifically, when performing current control, the headlight driving chip 102 can accurately control the working current of the matrix headlights to ensure stable brightness of the matrix headlights; when performing voltage regulation, the headlight driving chip 102 can adjust the working voltage of the matrix headlights according to requirements to adapt to different irradiation modes, and the specific irradiation modes can be referred to the subsequent embodiments; the headlight driving chip 102 can also be used to provide overload protection, that is, provide overcurrent protection or overvoltage protection to prevent circuit damage.

[0046] After receiving the mode control signal sent by the control unit 101, the matrix manager 103 controls the lighting of the matrix headlights at different angles on the lamp board according to the mode control signal. Specifically, the matrix manager 103 adjusts the irradiation angle of the matrix headlights according to the control instructions of the control unit 101 (such as an ECU) to optimize the lighting effect. Among them, the matrix manager 103 can automatically adjust the horizontal angle of the matrix headlights according to the body slope and steering angle to ensure that the lighting range covers the road ahead, that is, to achieve the horizontal angle adjustment of the matrix headlights; the matrix manager 103 can adjust the vertical angle of the matrix headlights according to the body pitch angle and load change to prevent dazzling and ensure clear vision, that is, to achieve the vertical angle adjustment of the matrix headlights.

[0047] Optionally, the structures of the matrix headlights at different angles on the lamp board include at least one of planar, upper-middle-lower, left-middle-right, or polygonal; the matrix manager 103 lights up the matrix headlights at the target angle corresponding to the mode according to the mode corresponding to the structure control signal.

[0048] It can be understood that the mode corresponding to the mode control signal is the irradiation mode. Based on the structures of the matrix headlights at different angles on the lamp board, the matrix manager 103 can light up the matrix headlights at the target angle corresponding to the mode according to the mode corresponding to the structure control signal to achieve dynamic lighting, intelligent anti-dazzle, or adaptive high and low beam conversion, etc. Exemplarily, Figure 2 The structural schematic of the matrix headlights provided by the embodiment of the present application Figure 1 , such as Figure 2As shown, the structure of the matrix headlights at different angles on the lamp board is planar. Figure 3 Schematic diagram of the structure of the matrix headlights provided by the embodiment of the present application Figure 2 , as Figure 3 shown, the structure of the matrix headlights at different angles on the lamp board is in an upper-middle-lower form, that is, the matrix headlights are arranged in three layers: upper, middle, and lower. Each layer can be controlled independently to adapt to different weather and road conditions, such as special lighting requirements when driving in fog, rain, or mountain roads. Figure 4 Schematic diagram of the structure of the matrix headlights provided by the embodiment of the present application Figure 3 , as Figure 4 shown, the structure of the matrix headlights at different angles on the lamp board is in a left-middle-right form, that is, the matrix headlights are designed into three independent irradiation areas: left, middle, and right, allowing the driver to adjust the irradiation direction according to the vehicle position, oncoming vehicle, and pedestrian position, thereby increasing driving safety. Figure 5 Schematic diagram of the structure of the matrix headlights provided by the embodiment of the present application Figure 4 , as Figure 5 shown, the structure of the matrix headlights at different angles on the lamp board is in a polygonal form, that is, an irregular polygon matrix design is adopted to intelligently adjust the irradiation angle and range of the matrix headlights according to the road surface conditions, ensuring the driving vision under complex road conditions.

[0049] The matrix headlight control system provided by the embodiment of the present application includes a control unit, a headlight driver chip, and a matrix manager; among them, the control unit is electrically connected to the headlight driver chip and the matrix manager respectively; the control unit is used to send a headlight drive signal to the headlight driver chip and a mode control signal to the matrix manager according to the received target signal, realizing automatic detection of the environment and determination of the optimal irradiation mode to adjust the matrix headlights to ensure the optimization of the lighting effect; the headlight driver chip is used to provide current and voltage for the matrix headlights according to the headlight drive signal; the matrix manager is used to control the lighting of the matrix headlights at different angles on the lamp board according to the mode control signal, and can intelligently adjust the irradiation mode and irradiation effect according to different driving environments, better meeting the lighting requirements of different roads, and improving the adaptability and safety of vehicle lighting.

[0050] Based on the above embodiments, Figure 6 Schematic diagram of the matrix headlight control system provided by another embodiment of the present application. Based on the above embodiments, the embodiment of the present application further explains the matrix headlight control system. As Figure 6As shown in the figure, in the matrix headlight control system 600 of the embodiment of the present application, the control unit is the ECU 601. The matrix headlight control system further includes a central control unit 602, which is electrically connected to the ECU 601 and is used to receive a target signal and send the target signal to the ECU 601. The ECU 601 receives the target signal, and according to the target signal, sends a headlight drive signal to the headlight drive chip 102 and sends a mode control signal to the matrix manager 103. The matrix headlight control system 600 may further include a vehicle body sensor 603 and matrix headlights 604.

[0051] Exemplarily, the central control unit 602 receives the target signal from the vehicle body sensor 603 and sends the target signal to the ECU 601. Correspondingly, the ECU 601 receives the target signal, and according to the target signal, sends a headlight drive signal to the headlight drive chip 102 and sends a mode control signal to the matrix manager 103. The headlight drive chip 102 provides current and voltage for the matrix headlights 604 according to the headlight drive signal. The matrix manager 103 controls the lighting of the matrix headlights 604 at different angles on the light board according to the mode control signal. Among them, the central control unit 602 is the brain of the entire matrix headlight control system 600, responsible for receiving, processing, and sending various control signals. Specifically, the central control unit 602 can obtain information such as the vehicle body slope, acceleration, and ambient light and darkness from the vehicle body sensor 603, perform data integration, and send the integrated data (i.e., the target signal) to the ECU 601. The vehicle body sensor 603 can monitor various state parameters of the vehicle in real time and transmit the data to the central control unit 602. The vehicle body sensor may include, for example, a vehicle body slope sensor, an acceleration sensor, and an ambient light sensor. Specifically, the vehicle body slope sensor is used to detect the pitch angle and roll angle of the vehicle to help adjust the angle of the matrix headlights 604. The acceleration sensor is used to detect the acceleration change of the vehicle to prevent visual discomfort caused by the matrix headlights 604 during acceleration or deceleration. The ambient light sensor is used to detect the intensity of external light and automatically adjust the brightness of the matrix headlights 604 to adapt to different lighting environments. The structure of the matrix headlights 604 at different angles on the light board can refer to the above embodiment and will not be elaborated here.

[0052] Based on the above embodiment, Figure 7 The figure is a schematic diagram of the matrix headlight control system provided by another embodiment of the present application. Based on the above embodiment, the embodiment of the present application further illustrates the matrix headlight control system. As Figure 7As shown, in the matrix headlight control system 700 according to an embodiment of the present application, the control unit is the central control unit 701. The central control unit 701 receives a target signal, and according to the target signal, sends a headlight driving signal to the headlight driving chip 102 and sends a mode control signal to the matrix manager 103. The matrix headlight control system 700 may further include a vehicle body sensor 603 and matrix headlights 604.

[0053] It can be understood that the ECU is not used in this embodiment. Exemplarily, the central control unit 701 may obtain information such as the vehicle body slope, acceleration, and ambient light and darkness from the vehicle body sensor 603, perform data integration, and determine the irradiation mode of the optimal matrix headlights according to the integrated data (i.e., the target signal), so as to send a headlight driving signal to the headlight driving chip 102 and send a mode control signal corresponding to the irradiation mode of the optimal matrix headlights to the matrix manager 103. Accordingly, the headlight driving chip 102 provides current and voltage for the matrix headlights 604 according to the headlight driving signal; the matrix manager 103 controls the lighting of the matrix headlights 604 at different angles located on the lamp board according to the mode control signal.

[0054] Based on the above embodiment, optionally, the matrix manager is electrically connected to the switching tube and the headlight lamp group of the matrix headlights, and the switching tube and the headlight lamp group of the matrix headlights are connected in parallel.

[0055] Exemplarily, Figure 8 is a connection schematic diagram of the switching tube and the matrix headlights provided by an embodiment of the present application. As Figure 8 shown, the switching tube 801 and the headlight lamp group 802 of the matrix headlights (illustrated by taking one LED lamp as an example) are connected in parallel, and the switching tube 803 and the headlight lamp group 804 of the matrix headlights (illustrated by taking one LED lamp as an example) are connected in parallel.

[0056] Based on the above embodiment, optionally, the matrix manager includes multiple channels, and the matrix manager controls the opening or closing of any one of the multiple channels.

[0057] Exemplarily, the matrix manager includes, for example, 12 channels. Each channel is composed of a switching tube and a headlight lamp group of the matrix headlights connected in parallel. Each headlight lamp group is composed of, for example, 1 to 3 LED lamps. The matrix manager can control the opening or closing of any one of the multiple channels.

[0058] Based on the above embodiment, in a possible implementation manner, the matrix manager may be specifically configured to: when the matrix manager controls at least one switching tube to close according to the mode control signal, the current flows through the switching tube and the headlight lamp group is short-circuited; when the matrix manager controls at least one switching tube to open according to the mode control signal, the current flows through the headlight lamp group and the headlight lamp group is lit.

[0059] Exemplarily, taking the vehicle lamp as an LED lamp as an example, when the matrix manager controls the switch tube to close according to the mode control signal, the current flows through the switch tube and the LED lamp group is short-circuited. When the matrix manager controls the switch tube to open according to the mode control signal, the current flows through the LED lamp group and the LED lamp group is lit. Thus, it can be realized that a control unit (such as an ECU) controls the individual lighting of different LED lamp groups at different angles on the lamp board, making the control more flexible.

[0060] In another possible implementation manner, at least one channel is electrically connected to the first branch and the second branch. The first branch is composed of an inverter and a first switch tube in parallel with the first vehicle lamp group of the matrix vehicle lamp, and the inverter is used to reverse the signal; the second branch is composed of a second switch tube and the second vehicle lamp group of the matrix vehicle lamp in parallel. The matrix manager can specifically be used for: when the matrix manager controls the first switch tube to close according to the mode control signal, the current flows through the first switch tube, the first vehicle lamp group is short-circuited, and controls the second switch tube to open, the current flows through the second vehicle lamp group, and the second vehicle lamp group is lit; when the matrix manager controls the first switch tube to open according to the mode control signal, the current flows through the first vehicle lamp group, the first vehicle lamp group is lit, and controls the second switch tube to close, the current flows through the second switch, and the second vehicle lamp group is short-circuited.

[0061] In this embodiment, exemplarily, one channel can be set to control two groups of LED lamp groups. Among them, the first branch includes an inverter, achieving the effect that only one of the two groups of LED lamp groups works at the same time without exceeding the threshold power of the device. For example, the first vehicle lamp group of the matrix vehicle lamp is arranged on the lamp board with a downward angle, and the second vehicle lamp group of the matrix vehicle lamp is arranged on the lamp board with an upward angle; when the matrix manager controls the first switch tube to close according to the mode control signal, the current flows through the first switch tube, the first vehicle lamp group is short-circuited, and controls the second switch tube to open, the current flows through the second vehicle lamp group, and the second vehicle lamp group is lit; when the matrix manager controls the first switch tube to open according to the mode control signal, the current flows through the first vehicle lamp group, the first vehicle lamp group is lit, and controls the second switch tube to close, the current flows through the second switch, and the second vehicle lamp group is short-circuited. By arranging the two groups of LED lamp groups on the lamp boards with opposite logics respectively, the corresponding functions can be realized, the circuit can be simplified, and the usage amount of the matrix manager and the control unit (such as an ECU) can be reduced.

[0062] Based on the above embodiments, optionally, the target signal includes a first signal corresponding to an inclination sensor, and the inclination sensor is used to detect the inclination angle of the road surface in front of the vehicle; the control unit determines a first angle corresponding to the matrix vehicle lamp according to the first signal; the matrix manager controls the lighting of the matrix vehicle lamp at the first angle on the lamp board.

[0063] Exemplarily, a slope sensor is installed at the front of the vehicle, for example, and can accurately detect the slope of the road surface in front of the vehicle. The slope sensor can be, for example, an inclination sensor, an acceleration sensor, or other sensors suitable for detecting the slope. Specifically, the control unit receives the data of the slope sensor (i.e., the first signal) and determines the optimal first angle corresponding to the matrix headlights. The matrix manager controls the lighting of the matrix headlights at the first angle located on the lamp panel. It can be understood that in this embodiment, the information of whether the road surface in front of the vehicle sensed by the slope sensor is uphill or downhill is used to automatically adjust the matrix headlights at different angles to be turned on, so as to compensate for the visual blind area caused by the vehicle tilt, and ensure that the lighting range of the matrix headlights always maintains the best match with the road surface, improving the safety of night driving.

[0064] Based on this embodiment, FIG. 9(a) is a schematic diagram of blind area lighting provided by an embodiment of the present application, and FIG. 9(b) is a schematic diagram of blind area lighting provided by another embodiment of the present application. As shown in FIGS. 9(a) and 9(b), when the vehicle is going downhill, the matrix headlights with a downwardly deflected opening angle are turned on to illuminate the road conditions below. Figure 10 A schematic diagram of blind area lighting provided by another embodiment of the present application, as Figure 10 shown, when the vehicle is going uphill, the matrix headlights with an upward opening angle can be turned on to illuminate the road conditions above.

[0065] On the basis of the above embodiment, optionally, the target signal includes a second signal corresponding to the steering of the vehicle steering wheel. The control unit determines the second angle corresponding to the matrix headlights according to the second signal; the matrix manager controls the lighting of the matrix headlights at the second angle located on the lamp panel.

[0066] In this embodiment, when the steering wheel steering data is detected, the matrix headlights in the corresponding irradiation direction on the lamp panel can be controlled to be turned on, so as to provide blind area lighting.

[0067] It can be understood that by setting a multi-angle lamp panel solution with lower cost to replace the solution of realizing lighting steering through a motor in the current technology, while achieving the same technical effect, the complexity of the solution can also be simplified.

[0068] On the basis of the above embodiment, optionally, the target signal includes a third signal corresponding to the acceleration sensor. The acceleration sensor is used to detect the vibration and tilt of the vehicle; the control unit determines the third angle corresponding to the matrix headlights according to the third signal; the matrix manager controls the lighting of the matrix headlights at the third angle located on the lamp panel.

[0069] Exemplarily, when the vehicle is driving on an uneven road surface, the acceleration sensor detects the vibration and tilt data of the vehicle. After the control unit analyzes this data (i.e., the third signal), it determines the third angle corresponding to the matrix headlights. The matrix manager controls the lighting of the matrix headlights at the third angle on the light board, so that the illuminated position in front of the vehicle does not change with the vehicle's jitter, thereby canceling the illumination jitter caused by the vehicle's vibration. The anti-shake of the Head Up Display (HUD) can also be adjusted based on the vibration and tilt data of the vehicle.

[0070] Based on the above embodiments, optionally, the target signal includes the fourth signal corresponding to the distance detection sensor, and the distance detection sensor is used to detect the distance of the trailing vehicle in real time; when the control unit determines that the distance of the trailing vehicle is less than the safety distance threshold according to the fourth signal, it sends a warning control instruction to the matrix manager; the matrix manager controls the vehicle taillights to display the target warning pattern according to the warning control instruction.

[0071] It can be understood that when the vehicle is driving at night or in low visibility conditions, the main function of the taillights is to remind the following vehicle of its presence and approximate position. However, traditional taillights have limited ability to express the vehicle's distance and cannot effectively warn the following vehicle to maintain a safe distance, resulting in traffic accidents caused by following too closely. In this embodiment, when the distance of the oncoming vehicle from behind is too close, a specific pattern will automatically flash to warn the driver behind to increase the distance from the vehicle in front, improving driving safety. Exemplarily, the distance detection sensor is installed at the rear of the vehicle to detect the distance of the trailing vehicle in real time and transmit the distance data (i.e., the fourth signal) to the control unit. After receiving the distance data, the control unit analyzes and processes it to determine whether to initiate a warning. If the control unit determines that the distance of the trailing vehicle is less than the safety distance threshold, it sends a warning control instruction to the matrix manager. The matrix manager integrates a pattern display driver program for controlling the taillights to display different warning patterns. When the matrix manager receives the warning control instruction sent by the control unit, it controls the vehicle taillights to display the target warning pattern according to the warning control instruction. The target warning pattern is, for example, a flashing arrow or a warning symbol to remind the following vehicle to maintain a safe distance. In this embodiment, the distance of the trailing vehicle is continuously monitored in real time. When it is determined that the distance of the trailing vehicle is greater than or equal to the safety distance threshold, that is, when the distance of the trailing vehicle returns to the safe range, the display of the target warning pattern stops.

[0072] Based on the above embodiments, optionally, the target signal includes a fifth signal corresponding to a V2X (a vehicle wireless communication technology) communication module. The control unit determines a linkage control strategy according to the fifth signal. The matrix manager adjusts the brightness and / or irradiation range of the matrix headlights according to the linkage control strategy. The linkage control strategy includes at least one of a first strategy in an emergency braking safety prompt mode, a second strategy in an energy-saving mode, or a third strategy in a large field of view mode.

[0073] Exemplarily, the V2X communication module is used to receive and send information between vehicles and send this information (i.e., the fifth signal) to the control unit. This information is, for example, vehicle status information detected by a vehicle status monitoring module, and this information includes but is not limited to information such as speed, acceleration, and braking status. The control unit determines a linkage control strategy according to the fifth signal, and the matrix manager adjusts the brightness and irradiation range of the matrix headlights according to the linkage control strategy. Among them, the linkage control strategy includes at least one of a first strategy in an emergency braking safety prompt mode, a second strategy in an energy-saving mode, or a third strategy in a large field of view mode. Specifically, for the first strategy in the emergency braking safety prompt mode, for example, when a vehicle in front in the same direction brakes suddenly, the vehicle in front will send a braking signal through the V2X communication module. After the vehicle behind receives this braking signal, the matrix manager of the vehicle in front will automatically increase the brightness of the brake lights to provide an obvious safety prompt for the vehicle coming from behind. For the second strategy in the energy-saving mode, for example, when there is a headlight illumination cross area among vehicles in the same direction, the vehicle behind obtains the headlight illumination information of the vehicle in front through the V2X communication module, and the control unit of the vehicle behind instructs the matrix manager to reduce the brightness of the headlights of the vehicle behind, reduce energy consumption, and prevent glare. For the third strategy in the large field of view mode, for example, when there is a headlight illumination cross area among vehicles in the same direction, the vehicle behind obtains the headlight illumination information of the vehicle in front through the V2X communication module, reduces the brightness directly in front, and at the same time increases the brightness on the left and right sides, which is executed by the control unit to achieve the large field of view effect of non-blind spot illumination. Through the intelligent linkage between the headlights and the V2X communication module in this embodiment, energy conservation can be achieved while ensuring safety.
