[0032] Next, the technical solutions in the present application will be clearly and elaborately described in conjunction with the accompanying drawings. Among them, in the description of the embodiments of the present application, unless otherwise specified, " / " means "or". For example, A / B may mean A or B. The "and / or" in the text is only a description of the association relationship of the associated objects, indicating that there can be three relationships. For example, A and / or B can mean: A exists alone, A and B exist simultaneously, and B exists alone. In addition, in the description of the embodiments of the present application, "a plurality" means two or more than two.

[0033] Hereinafter, the terms "first" and "second" are only used for descriptive purposes and cannot be understood as implying or suggesting relative importance or implicitly indicating the quantity of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include one or more of such features.

[0034] With the rapid development of intelligent vehicles, there are more and more display lamps on vehicles. For example, currently, vehicles are generally equipped with a front projection display screen, a rear projection display screen, an in-vehicle projection lamp, and various display lighting lamps, etc. In related technologies, display lamps are usually connected to the body domain controller, and the body domain controller correspondingly controls the display effects of the display lamps. However, when controlled by the body domain controller, usually only the light-emitting diode (LED) lamp board in the display lamp is lit to achieve basic lighting display. The body domain controller cannot simultaneously control the display lamp to achieve different display effects, and the display effects are monotonous.

[0035] Therefore, the embodiments of the present application provide a lighting control system, a vehicle control system, and a vehicle. The lighting control system enables the display lamp to simultaneously achieve different display effects through a control module, so that while realizing the original lighting display, the display lamp can present more display effects and enrich the display effects.

[0036] The following will give an exemplary description of the lighting control system, the vehicle control system, and the vehicle provided by the embodiments of the present application in combination with the drawings.

[0037] The vehicle control system provided by the embodiments of the present application is applied to a vehicle. As Figure 1 shown, the vehicle control system may include a body domain controller 1, a lighting control system 2, and a cockpit domain controller (HUT) 3. Among them, the first end of the body domain controller 1 and the first end of the cockpit domain controller 3 are connected through a controller area network bus to achieve data communication. The second end of the body domain controller 1 is connected to the first end of the lighting control system 2. Specifically, it can be connected through a controller area network bus to send the first information to the lighting control system 2. The lighting control system 2 can generate a first control signal based on the first information. The second end of the cockpit domain controller 3 is connected to the second end of the lighting control system 2. Specifically, it can be connected through Ethernet to send the second information to the lighting control system 2, where the second information includes information such as image and animation signals. The lighting control system 2 can generate a second control signal based on the second information. The first control signal and the second control signal are used to control the display state of the display lamps in the vehicle, such as the front LED headlamp, the rear LED headlamp, and the projection display screen, etc. In this way, the lighting control system 2 in the present application can control the display lamps in the vehicle to achieve different display effects based on the first information and the second information. In this way, while realizing the original lighting display, the lighting control system 2 can make the display lamps present more display effects to enrich the display effects and achieve full-domain scene lighting and display.

[0038] Specifically, in one example, as Figure 2As shown in the figure, the lighting control system 2 may include a control module 21, a first display module 22, and a second display module 23. Among them, the first end of the control module 21 is connected to the second end of the body domain controller 1. Specifically, the connection can be achieved through a controller area network bus, and it is used to receive the first information sent by the body domain controller 1 and generate a first control signal according to the first information. The second end of the control module 21 is connected to the second end of the cockpit domain controller 3. Specifically, the connection can be achieved through Ethernet, and it is used to receive the second information sent by the cockpit domain controller 3 and generate a second control signal according to the second information. In this way, after receiving the first information and the second information, the control module 21 can generate corresponding first control signals and second control signals according to the first information and the second information respectively to control the display state of the display lamps. Exemplarily, assuming that the first information represents a steering signal and the second information represents a projection animation signal, the control module 21 can control the corresponding first display module 22 and second display module 23 to perform steering display and projection animation display based on the steering signal and the projection animation signal.

[0039] Here, it is worth noting that, in order to enrich the display effect, the control module 21 in the embodiment of the present application can control multiple display lamps to perform steering display and projection animation display simultaneously; in order to ensure the display accuracy of the display lamps, the control module 21 in the embodiment of the present application can also control multiple display lamps to perform steering display or projection animation display separately at different times. For example, assuming that the user wants to remind other vehicles that the vehicle needs to turn left, the body domain controller 1 sends a steering signal to the control module 21. If the control module 21 is controlling other display lamps for projection based on the projection signal at this time, the control module 21 can output a first control signal corresponding to a left turn to the display lamps in the first display module 22 and the second display module 23. At the same time, it stops outputting the second control signal corresponding to the projection signal to the projection lamps in the first display module 22 and the second display module 23 to avoid the problem that the steering display effect is low due to the influence of the projection animation during steering and ensure the display accuracy of the display lamps. Specifically, corresponding settings can be made based on actual needs, and the present application does not make specific limitations on this.

[0040] The first display module 22 and the second display module 23 can generate corresponding drive signals based on the first control signal and / or the second control signal sent by the control module 21 to drive the corresponding display lamps to display.

[0041] In an example, such as Figure 3As shown, the first display module 22 may include a first driving unit 221 and a first lighting unit 222. The input end of the first driving unit 221 is connected to the third end of the control module 21, and the output end of the first driving unit 221 is connected to the input end of the first lighting unit 222. After receiving the first control signal and / or the second control signal sent by the control module 21, the first driving unit 221 drives the first lighting unit 222 to perform corresponding displays.

[0042] Among them, the first lighting unit 222 may be a display lighting fixture at the front of the vehicle. The display lighting fixture at the front of the vehicle includes a left display lighting fixture and a right display lighting fixture. To ensure the driving accuracy of the first driving unit 221, two first driving units 221 may be correspondingly provided at this time, respectively driving the left display lighting fixture and the right display lighting fixture. Specifically, as Figure 4 shown, the first lighting unit 222 may include a left front first driving unit 221a and a right front first driving unit 221b. The left display lighting fixture and the right display lighting fixture may include a left front side interactive screen 222a, a left front side LED projection lamp 222b, and a left front side display lamp 222c, etc. The right display lighting fixture may include a right front side interactive screen 222d, a right front side LED projection lamp 222e, and a right front side display lamp 222f, etc. Other display lighting fixtures at the front of the vehicle may also be provided based on the vehicle, for example, a front side logo lamp, a front side through lamp, etc. In this regard, the present application does not make specific limitations.

[0043] Among them, the left front side interactive screen 222a and the right front side interactive screen 222d are intelligent lights, that is, the user can change the display effects and display contents of the left front side interactive screen 222a and the right front side interactive screen 222d through the control module 21, a lighting software (Application, APP), etc. to achieve the purpose of intelligent interaction. The first lighting unit 222 may also include pixel headlights, and the display effects and display contents of the pixel headlights can also be correspondingly changed through the control module 21, a lighting software (Application, APP), etc. to further achieve the purpose of intelligent interaction.

[0044] Since the first lighting unit 222 includes multiple display lighting fixtures, in order to enable the first driving unit 221 to drive the corresponding display lighting fixtures to achieve displays based on different first control signals and second control signals to ensure display reliability, as Figure 5As shown, the first driving unit 221 may include a controller 2211 and a switching circuit 2212. The first end of the controller 2211 is used to access the first control signal. The first end of the switching circuit 2212 is used to access the first control signal and / or the second control signal. The second end of the switching circuit 2212 is connected to the second end of the controller 2211 and is used to access the switching signal. The third end of the switching circuit 2212 is connected to the first lighting unit 222. The switching circuit 2212 can drive the first driving unit 222 to display according to the first control signal and / or the second control signal, and switch the display state of the first lighting unit 222 according to the first control signal and the switching signal. Here, it is worth noting that the switching signal is a signal used to switch the display state of the first lighting unit 222. For example, assuming that the initial display of the first lighting unit 222 is low beam display, when the vehicle travels to a dim area and high beam display is required, the switching signal is to turn off the low beam display and turn on the high beam display, that is, the signal for switching from low beam display to high beam display.

[0045] Optionally, as Figure 6 shown, the display state includes at least one or more of low beam (LB) display, high beam (HB) display, turn signal display, daytime running lamps (DRL) display, adaptive driving beam (ADB) display, adaptive front lighting system (AFS), or lighting height adjustable display. It may also include other display states. In this regard, the present application does not make specific limitations.

[0046] Among them, the lighting height adjustable display may be an automatic headlamp leveling system (ALS) adjusted using a set algorithm, or an electric control structure electrically adjusted through a mechanical structure. In this regard, the present application does not make specific limitations.

[0047] In this way, the controller 2211 in the present application can generate a corresponding switching signal based on the first control signal and / or the second control signal sent by the control module 21 to flexibly switch the display state of the display lamps in the first lighting unit 222, with strong real-time performance, simple operation, and rich display effects can be achieved.

[0048] Exemplarily, as Figure 7As shown, the controller 2211 may include a microcontroller 22111 (Microcontroller Unit, MCU), a voltage regulator 22112, a power integrator 22113, a digital-to-analog converter 22114, and multiple level converters 22115. The first control signal is input to the input end of the power integrator 22113. At this time, the first control signal includes an LB signal and an HB signal. The power integrator 22113 can integrate the LB signal and the HB signal into one signal and input it to the input end of the voltage regulator 22112. The voltage regulator 22112 sends a 5V (volt) level signal and a display signal to the microcontroller 22111 based on this signal. To ensure the input reliability of the LB signal and the HB signal, the two input ends of the power integrator 22113 can be respectively connected to a diode (Diode, D). The positive poles of the diodes D are respectively connected to the LB signal and the HB signal, and the negative poles of the diodes D are connected to the two input ends of the power integrator 22113 to ensure the transmission reliability of the LB signal and the HB signal.

[0049] The microcontroller 22111 has multiple pins. Among them, the first pin of the microcontroller 22111 is connected to the output end of the voltage regulator 22112, and the second pin of the microcontroller 22111 is connected to a level converter 22115. The multiple input ends of this level converter 22115 are respectively used to access the first control signal. For example, the LB signal, the HB signal, the DRL signal, etc. At the same time, this level converter 22115 also has multiple corresponding output ends to output corresponding signals to the microcontroller 22111. To ensure the input reliability of the first control signal, the multiple input ends of the level converter 22115 can be respectively connected to a diode D. The positive pole of the diode D is used to access the first control signal, and the negative pole of the diode D is connected to the multiple input ends of the level converter 22115 to ensure the transmission reliability of the first control signal. Further, the output ends of the multiple diodes D can also be connected to a signal input reverse connection protector 22116 to further improve the transmission reliability of the first control signal. The third pin of the microcontroller 22111 can be connected to a digital-to-analog converter 22114 for outputting a first switching signal through this digital-to-analog converter 22114. The other pins of the microcontroller 22111 can be set based on different scenarios. Regarding this, the present application does not make specific limitations.

[0050] Optionally, the voltage regulation unit 22112 can be a low dropout regulator (LDO). The LDO has the advantages of low noise, high precision, and low voltage drop, which can improve the reliability of the LDO input and output signals.

[0051] To enable the first driving unit 222 to flexibly switch the display state, in one example, such as Figure 8As shown, the switch circuit 2212 may include a first switch sub-circuit. The first switch sub-circuit includes a first voltage converter DCDC1, a first switching transistor Q1, and a second switching transistor Q2. The first lighting unit 222 includes a first lighting sub-unit 2221 and a second lighting sub-unit 2222. Among them, the first end of the first voltage converter DCDC1 is connected to the second end of the controller 2211 for accessing a first switching signal. The second end of the first voltage converter DCDC1 is connected to the third end of the controller 2211 for outputting a first feedback signal to the controller 2211. The third end of the first voltage converter DCDC1 is used for accessing a first control signal. The controlled ends of the first switching transistor Q1 and the second switching transistor Q2 are respectively connected to the fourth end of the controller 2211 for accessing a first switch control signal and a second switch control signal. The first ends of the first switching transistor Q1 and the second switching transistor Q2 are the output ends of the switch circuit 2212. One end of the first lighting sub-unit 2221 and one end of the second lighting sub-unit 2222 are respectively connected to the fourth end of the first voltage converter DCDC1. The other end of the first lighting sub-unit 2221 is connected to the second end of the first switching transistor Q1. The other end of the second lighting sub-unit 2222 is connected to the second end of the second switching transistor Q2. Among them, the display states corresponding to the first lighting sub-unit 2221 and the second lighting sub-unit 2222 are different.

[0052] In this example, the controller 2211 is configured to output a first switching signal to switch the state of the first voltage converter DCDC1 after receiving the first control signal, and is further configured to output a first switch control signal and a second switch control signal to control the on / off of the first switching transistor Q1 and the second switching transistor Q2, so as to switch the display state of the first lighting unit 222. For example, assuming that the display state corresponding to the first lighting sub-unit 2221 is turn signal display, and the display state corresponding to the second lighting sub-unit 2222 is daytime position display. When the first control signal is a turn signal, indicating that the first lighting unit 222 is required to present turn signal display, the controller 2211 controls the first switching transistor Q1 to conduct and the second switching transistor Q2 to turn off, so that the first lighting unit 222 presents turn signal display. Conversely, it controls the first switching transistor Q1 to turn off and the second switching transistor Q2 to conduct. In this way, by controlling the on / off of the first switching transistor Q1 and the second switching transistor Q2, the first lighting unit 222 can present different states, and the structure is simple.

[0053] In this example, the first voltage converter DCDC1 can be either a boost converter or a buck-boost converter. After receiving the first control signal, the controller 2211 can output a first switching signal to switch the state of the first voltage converter DCDC1, so as to adapt to different lighting sub-units, which can be specifically set according to different display states. The present application does not make specific limitations in this regard.

[0054] Optionally, the first lighting sub-unit 2221 and the second lighting sub-unit 2222 can each include a plurality of series-connected LEDs. When the first switching transistor Q1 corresponding to the first lighting sub-unit 2221 is turned on, the plurality of series-connected LEDs in the first lighting sub-unit 2221 emit light correspondingly; when the second switching transistor Q2 corresponding to the second lighting sub-unit 2222 is turned on, the plurality of series-connected LEDs in the first lighting sub-unit 2221 emit light correspondingly. The first switching transistor Q1 and the second switching transistor Q2 can be any one of an N-type metal-oxide-semiconductor (NMOS) transistor, a P-type metal-oxide-semiconductor (PMOS) transistor, an NPN bipolar junction transistor, a PNP bipolar junction transistor, or a relay, or can also be other devices or circuits with a switching function. The present application does not make specific limitations in this regard.

[0055] In another example, as Figure 9 shown, the switching circuit 2212 can include a second switching sub-circuit. The second switching sub-circuit includes a second voltage converter DCDC2 and a third switching transistor Q3. The first lighting unit 222 includes a third lighting sub-unit 2223 and a fourth lighting sub-unit 2224. The first terminal of the second voltage converter DCDC2 is connected to the second terminal of the controller 2211 for receiving a second switching signal. The second terminal of the second voltage converter DCDC2 is connected to the third terminal of the controller 2211 for outputting a second feedback signal to the controller 2211. The third terminal of the second voltage converter DCDC2 is used for receiving the first control signal. The controlled terminal of the third switching transistor Q3 is connected to the fifth terminal of the controller 2211 for receiving a third switching control signal. One end of the third lighting sub-unit 2223 is connected to the fourth terminal of the second voltage converter DCDC2. The other end of the third lighting sub-unit 2223 is connected to the second terminal of the third switching transistor Q3 and one end of the fourth lighting sub-unit 2224. The other end of the fourth lighting sub-unit 2224 and the first terminal of the third switching transistor Q3 are the output terminals of the switching circuit 2212. Among them, the display states corresponding to the third lighting sub-unit 2223 and the fourth lighting sub-unit 2224 are different.

[0056] In this example, the controller 2211 is configured to output a second switching signal to switch the state of the second voltage converter DCDC2 after receiving the first control signal, and is also configured to output a third switch control signal to control the on / off of the third switch transistor Q3, so as to switch the display state of the first lighting unit 222. For example, assuming that the display state corresponding to the third lighting sub-unit 2223 is low beam display, and the display state corresponding to the fourth lighting sub-unit 2224 is high beam display, when the first control signal is a low beam signal, indicating that the first lighting unit 222 needs to present a low beam display, the controller 2211 controls the third switch transistor Q3 to turn off, so that the first lighting unit 222 presents a low beam display. Conversely, it controls the third switch transistor Q3 to turn on. In this way, by controlling the on / off of the third switch transistor Q3, the first lighting unit 222 can present different states, and the structure is simple.

[0057] In this example, the second voltage converter DCDC2 can be any one of a boost converter and a buck-boost converter. The controller 2211 can output a second switching signal to switch the state of the second voltage converter DCDC2 after receiving the first control signal, so as to adapt to different lighting sub-units, and can be specifically set according to different states of the Xina. For this, the present application does not make specific limitations.

[0058] Optionally, the third lighting sub-unit 2223 and the fourth lighting sub-unit 2224 can each include a plurality of serially connected LEDs. The third switch transistor Q3 can be any one of an NMOS transistor, a PMOS transistor, an NPN bipolar transistor, a PNP bipolar transistor or a relay, or can also be other devices or circuits with a switching function. For this, the present application does not make specific limitations.

[0059] To ensure the accuracy and reliability of the signals received by the switch circuit 2212, in one example, the switch circuit 2212 can include a filter and a protector. The input end of the filter is connected to the first control signal. The filter can perform filtering processing on the first control signal to filter out interference signals in the signal. The first end of the protector is connected to the first control signal, and the second end of the protector is connected to the input end of the filter. By means of the filter and the protector, the accuracy of the signals received by the switch circuit 2212 can be ensured, and further the reliability of the use of the switch circuit 2212 can be ensured.

[0060] Exemplarily, as Figure 10 shown, the filter can be an electromagnetic compatibility filter (EMC), and the protector can be a plurality of diodes D.

[0061] In summary, the control module 21 provided by the embodiments of the present application can control the display state and projection state of the first display module 22 based on the first information sent by the body domain controller 1 and the second information sent by the cockpit domain controller 3, so that the first display module 22 can achieve different display effects. For example, while the first display module 22 performs lighting display, by receiving different second information, different projection animations or projection symbols can be presented. In this way, while realizing the original lighting display, the lighting control system 2 can enable the display lamps to present more display effects, so as to enrich the display effects and achieve full-domain scene lighting and display.

[0062] Here, it is worth noting that the full-domain scene at this time means that based on the control module 21, the vehicle can achieve displays in multiple usage scenarios, such as lighting safety scenarios, driving etiquette scenarios, intelligent interaction scenarios, auxiliary support scenarios, and entertainment life scenarios, etc. Its multiple usage scenarios can specifically include external atmosphere, etc., night driving lights, driver assistance projection, pedestrian reminder, road markings, obstacle markings, welcome light carpet, vehicle condition information reminder, fixed-value animation, guiding signs, light shows, game voting, and concerts, etc., which enriches the display effects of the vehicle's display lamps. For this, it can be set based on actual needs, and the present application does not make specific limitations on this.

[0063] In one example, as Figure 11 shown, the second display module 23 provided by the embodiments of the present application can include a second driving unit 231 and a second lamp unit 232. The input end of the second driving unit 231 is connected to the fourth end of the control module 21, and the output end of the second driving unit 231 is connected to the input end of the second lamp unit 232. The second driving unit 231 is configured to drive the second lamp unit 232 to display after receiving the first control signal and / or the second control signal sent by the control module 21.

[0064] The second display module 23 can generate corresponding driving signals based on the first control signal and / or the second control signal sent by the control module 21 to drive the corresponding display lamps to display.

[0065] Among them, the second lamp unit 232 is the display lamp at the rear of the vehicle. The display lamp at the rear of the vehicle includes a left display lamp and a right display lamp. In order to ensure the driving accuracy of the second driving unit 231, two second driving units 231 can be correspondingly provided at this time, respectively corresponding to driving the left display lamp and the right display lamp. Specifically, as Figure 12As shown, the second lighting unit 232 may include a left-tail first driving unit 232a and a right-tail driving unit 232b. The left-side display lighting includes a left-tail side interaction screen 222a, a left-tail side combined light 222b, a left-tail side through light 222c, etc. The right-side display lighting includes a right-tail side interaction screen 222d, a right-tail side combined light 222e, a right-tail side through light 222f, etc. Other display lighting for the vehicle tail can also be set based on the vehicle, such as a tail logo light, etc. For this, the present application does not make specific limitations.

[0066] The second driving unit 231 in the embodiment of the present application may also include a controller and a switch circuit. For the specific structure and beneficial effects, reference may be made to the specific structure and beneficial effects of the first driving unit 221 above.

[0068] In order to enable the display lighting to present more display effects and further enrich the display effects, in another example, as Figure 13 shown, the lighting control system 2 may further include a third display module 24 and a projection module 25. The input end of the third display module 24 is connected to the fifth end of the control module 21 through a Local Interconnect Network (LIN) communication network protocol. The input end of the projection module 25 is connected to the sixth end of the control module 21 through a Low-Voltage Differential Signaling (LVDS) interface. The control module 21 can control the lighting display of the third display module 24 and the projection display of the projection module 25 according to the first information and the second information. Here, it is worth noting that the above-mentioned first display module 22 and second display module 23 are also connected to the control module 21 through an LVDS interface.

[0069] Among them, optionally, the third display module 24 may include a third driving unit and a third lighting unit. The third lighting unit may include a left door interactive screen, a right door interactive screen, an exterior color-changing ambient light (for example, a front ambient light, side ambient lights, a rear ambient light, and an ADS ambient light), a left license plate light, a right license plate light, a left turn signal, a right turn signal, a left floor lamp, and a right floor lamp, etc. Here, it is worth noting that the control module 21 may output multiple first control signals and second control signals simultaneously, so that the vehicle can present more display effects. For example, the first control signals output by the control module 21 may be a low beam display signal, an ADS ambient light signal, a left floor lamp signal, and a right floor lamp signal, so that the vehicle can achieve multiple effects simultaneously.

[0070] Among them, the third lighting unit may further include a driving assistance lamp, that is, the user can change the display effect and display content of the driving assistance lamp through the control module 21, a lighting software (Application, APP), etc., to achieve the purpose of intelligent assistance.

[0071] Optionally, the projection module 25 may include a fourth driving unit and a fourth lighting unit. The fourth lighting unit may include semi-dynamic signal projection (for example, a left front projection lamp, a left projection lamp, a left rear projection lamp, a right front projection lamp, a right projection lamp, and a right rear projection lamp) and an animation projection lamp (for example, a front digital projection lamp, a left digital projection lamp, a rear digital projection lamp, and a right digital projection lamp), etc., which can be added based on actual needs. For this, the present application does not make specific restrictions.

[0072] In summary, in the lighting control system 2 provided by the embodiments of the present application, the control module 21 may generate corresponding first and second control signals based on the first and second information sent by the body domain controller 1 and the cockpit domain controller 3, so that the first display module 23, the second display module 23, the third display module 24, the projection module 25, and even more display lamps can simultaneously achieve different display effects, so as to make the display lamps present more display effects while realizing the original lighting display, enriching the display effects.

[0073] The vehicle control system provided by the embodiments of the present application may further include an Instrument Panel (IP), an Intelligent Front Camera (IFC), an Antilock Brake System (ABS), an intelligent driving domain controller, a Telematics BOX (T-BOX), etc. For this, the present application does not make specific restrictions.
