Referring to fig. 1, an embodiment of the present disclosure provides a lamp control system 100 and a vehicle 200 equipped with the lamp control system 100. Vehicle 200 refers to a powered or towed vehicle for use by a person or for transporting items, including but not limited to cars, midbuses, buses, and the like. In the present embodiment, the vehicle 200 includes a vehicle body 210 and a power battery pack 230, the power battery pack 230 and the lamp control system 100 are disposed in the vehicle body 210, and the power battery pack 230 is electrically connected to the lamp control system 100 and provides electric energy for a part of the structure (e.g., an electronic control module) in the lamp control system 100. In the case that the vehicle 200 is a new energy vehicle, the power battery pack 230 can also provide driving force for the new energy vehicle, and further drive the driving system (e.g., axles and wheels) to operate through the transmission system.

Referring to fig. 2, the lamp control system 100 includes a first lamp module 110, N second lamp modules 130, N switch modules 150, and an electronic control module 170. The N second lamp modules 130 are respectively connected in parallel to the first lamp module 110, current input ends of the N second lamp modules 130 are connected to the current input end of the first lamp module 110 to form a common end 190, and N is a natural number greater than 0. The value of N can be set according to the design requirements of the vehicle. Specifically, the value of N may be 1, 2, 3, and so on. In the embodiments of the present application, only the value of N is 2. The ith switch module 150 of the N switch modules 150 is connected to the branch where the ith second lamp module 130 of the N second lamp modules 130 is located, and i is a natural number less than or equal to N. Specifically, one end of the ith second lamp module 130 is connected to the ith switch module 150, and the other end is connected to the electronic control module 170. The electronic control module 170 includes an output 1710, the output 1710 being connected to the N switch modules 150 and directly connected to the common terminal 190, the electronic control module 170 being configured to: the driving signal is input to the first lamp module 110 via the common terminal 190 to control the first lamp module 110 to operate in the first lighting mode, and is also input to the N switch modules 150 to drive the N switch modules 150 to control at least one of the N second lamp modules 130 to operate in the second lighting mode.

In the vehicle lamp Control system 100 provided in this embodiment, the Electronic Control module 170 is an Electronic Control Unit (ECU) in the vehicle 200, the first vehicle lamp module 110, the N second vehicle lamp modules 130, and the N switch modules 150 are hardware modules of a vehicle lamp, and the Electronic Control module is connected to each hardware module of the vehicle lamp through a vehicle-mounted hard wire, and implements power supply or lighting Control for each hardware module through the vehicle-mounted hard wire. In fig. 2, the on-vehicle hard wire is connected to the output terminal 1710 of the electronic control module 170 and the common terminal 190, that is, the output terminal 1710 is directly connected to the common terminal 190 through the on-vehicle hard wire, so that when the electronic control module 170 outputs the driving signal, the levels of the common terminal 190 and the output terminal 1710 are almost the same.

On the one hand, through this on-vehicle hardwire, electronic control module can provide power supply signal to first vehicle light module and N second vehicle light module, realizes the power supply to first vehicle light module and N second vehicle light module, because first vehicle light module place branch road does not insert the switch module, consequently, power supply signal can directly light first vehicle light module for first vehicle light module work is in first mode of lighting, also promptly, often lights the mode. On the other hand, through the on-vehicle hard wire, the electronic control module may provide the lighting control signal to the N second lamp modules, thereby implementing the lighting control of the N second lamp modules, so that at least one of the N second lamp modules operates in the second lighting mode, that is, controls the lighting mode. Wherein the operating parameters of the second lighting mode are different from the operating parameters of the first lighting mode. Specifically, the operating parameters may be the brightness, the lighting time period, the operating power, and the like of the vehicle lamp. Therefore, in the application, the electronic control module can directly realize power supply and control of the car lamp module through the vehicle-mounted hard wire, namely, the car lamp control system does not need to be provided with an additional car lamp processor, so that a hardware circuit of the car lamp control system is simplified, and the hardware cost of the car lamp control system is saved.

In some embodiments, referring to fig. 3, the driving signal output by the electronic control module 170 includes a Pulse Width Modulation (PWM) signal having a specific period, i.e., a lighting control signal. The PWM signal is a square wave signal having a specified period, and the time interval between two adjacent high level signals in the square wave signal is a fixed period of the PWM signal. In the present embodiment, the ith switch module 150 includes a timing unit 1510 and a switch unit 1530. The switch unit 1530 of the ith switch module 150 is connected to the branch where the ith second lamp module 130 is located, and is used for switching off or switching on the branch where the ith second lamp module 130 is located. The timing unit 1510 is connected between the output end 1710 of the electronic control module 170 and the switch unit 1530 of the i-th switch module 150, and is configured to output a specified level signal to the switch unit 1530 of the i-th switch module 150 when the specified period is greater than the period threshold, where the specified level signal is used to turn on the branch where the i-th second lamp module 130 is located, and at this time, the second lamp module 130 operates in the second lighting mode.

In addition, when the driving signal output by the electronic control module 170 includes the PWM signal, the driving signal further includes a power supply signal, that is, the driving signal may be regarded as a superimposed signal of the PWM signal and the power supply signal, where the power supply signal is used for supplying power to the first lamp module 110 and the N second lamp modules 130. Specifically, the power supply signal may be a high level signal having an amplitude greater than 3V, for example, a high level signal having an amplitude of 3.5V.

It should be noted that in the case that N is greater than 1, that is, the lamp control system 100 includes a plurality of second lamp modules 130. The plurality of switch units 1530 are connected to the branch where the plurality of second lamp modules 130 are located in a one-to-one correspondence manner, and the cycle thresholds in the timing units 1510 corresponding to the plurality of switch units 1530 may be the same or different. When the period thresholds of the timing units 1510 corresponding to the switch units 1530 are different from each other, the electronic control module 170 may adjust the designated period corresponding to the PWM signal, so that the timing unit 1510 outputs a designated level signal when the designated period of the PWM signal is greater than the period threshold thereof, and further controls the corresponding switch module 150 to turn on the branch where the second lamp module 130 is located, so as to turn on the second lamp module 130. On the contrary, when the designated period of the PWM signal is less than or equal to the period threshold of the timing unit 1510, the designated level signal cannot be output, so that the switch module 150 is in the off state, and the corresponding second lamp module 130 is turned off. In this way, the lighting control of the plurality of second lamp modules 130 can be realized by one PWM signal.

The following describes in detail the specific implementation of each hardware module in the vehicle lamp control system 100 and the lighting process of the vehicle lamp module.

Specifically, a current input end formed by connecting the plurality of third beads 1331 in series is connected to the common terminal 190, that is, a current input end formed by connecting the plurality of third beads 1331 in series is also connected to the output terminal 1710 of the electronic control module 170. The current output end formed by the series connection of the third lamp beads 1331 is connected to the second switch module 154 and then grounded.

In some embodiments, the plurality of first light beads 111, the plurality of second light beads 1311, and the plurality of third light beads 1331 are arranged to form a light bead array. Specifically referring to fig. 5, the plurality of first lamp beads 111, the plurality of second lamp beads 1311, and the plurality of third lamp beads 1331 are arranged to form a rectangular lamp bead array, the size of the rectangular lamp bead array is 20 × 20, wherein black lamp beads in fig. 5 are the first lamp beads 111, and the plurality of first lamp beads 111 are disposed on the outermost layer of the rectangular lamp bead array.

Specifically, the first lamp bead 111, the second lamp bead 1311, and the third lamp bead 1331 may be LED lamp beads, and the operating parameters of each LED lamp bead may be the same or different. Exemplarily, the first lamp bead 111 corresponds to a yellow LED lamp bead, the second lamp bead 1311 corresponds to a red LED lamp bead, and the third lamp bead 1331 corresponds to a white LED lamp bead, which is not specifically limited in this embodiment of the present application.

The N switch modules 150 include a first switch module 152 and a second switch module 154, the first switch module 152 is connected to the branch of the first vehicle lamp sub-module 1310, and the second switch module 154 is connected to the branch of the second vehicle lamp sub-module 1330. That is, the first switch module 152 is used to turn on or off the branch where the first lamp sub-module 1310 is located, and the second switch module 154 is used to turn on or off the branch where the second lamp sub-module 1330 is located.

Specifically, the driving signal generated by the electronic control module 170 includes a pulse width modulation signal (i.e., a PWM signal) having a specified period. In the embodiment shown in fig. 4, the first switching module 152 includes a first timing unit 1521 and a first switching unit 1523. The first switch unit 1523 is connected to the branch where the first vehicle lamp sub-module 1310 is located. The first timing unit 1521 is connected between the output end 1710 of the electronic control module 170 and the first switch unit 1523, and configured to output a first specified level signal to the first switch unit 1523 when the specified period is greater than the first period threshold, where the first specified level signal is used to turn on a branch where the first vehicle lamp module 1310 is located.

In some embodiments, the first timing unit 1521 may be a PWM window timing circuit, an input of which is a PWM signal generated by the electronic control module 170, the PWM window timing circuit is configured to time a specified period of the PWM signal, and in a case that the specified period is greater than a first period threshold, the PWM window timing circuit outputs a first specified level signal, which is, for example, a low level signal, an amplitude of the low level signal is less than 0.7V, for example, an amplitude of the low level signal is 0.3V. Conversely, in the case where the specified period is less than or equal to the first period threshold, the PWM window timing circuit outputs a high level signal having an amplitude greater than 3V, for example, an amplitude of 3.5V. Specifically, the PWM window timing circuit may be implemented by an electronic circuit, or may be implemented by a chip having a timing function, which is not specifically limited in this embodiment.

In some possible embodiments, the first switch unit 1523 includes a first field effect transistor Q1, and the first field effect transistor Q1 is a voltage control type semiconductor device. Wherein, the drain of the first field effect transistor Q1 is connected to the current output terminal of the first vehicle lamp sub-module 1310. The source of the first field effect transistor Q1 is connected to the current output terminal of the first lamp module 110 and is grounded. The gate of the first field effect transistor Q1 is connected to the signal output terminal of the first timing unit 1521. Specifically, in the embodiment shown in fig. 4, the first field effect transistor Q1 is a P-channel field effect transistor, that is, when the voltage between the gate and the source of the first field effect transistor Q1 is greater than the turn-on voltage, the drain and the source are conducted, and the branch of the first vehicle lamp sub-module 1310 is conducted. Since the source is grounded in fig. 4, when the voltage of the gate is greater than the turn-on voltage, the branch in which the first vehicle lamp sub-module 1310 is located is turned on. Therefore, the electronic control module 170 controls the first timing unit 1521 to output different level signals through the generated PWM signals with different specified periods, so as to control the branch circuit where the first vehicle lamp sub-module 1310 is located to be turned on or off. For example, when the specified period of the PWM signal is less than or equal to the first period threshold, the first timing unit 1521 outputs a high level signal, and the first field effect transistor Q1 is turned on, and the first vehicle lamp sub-module 1310 is turned on. On the contrary, when the designated period of the PWM signal is greater than the first period threshold, the first timing unit 1521 outputs a low level signal, and at this time, the first field effect transistor Q1 is not turned on, and the first vehicle lamp sub-module 1310 is not turned on.

In some possible embodiments, referring to fig. 6, the first switch unit 1523 includes a third field effect transistor Q3 and a fourth field effect transistor Q4. Wherein, the drain of the third field effect transistor Q3 is connected to the current output terminal of the first vehicle lamp sub-module 1310. The source of the third field effect transistor Q3 is connected to the current output terminal of the first lamp module 110 and is grounded. The gate of the third field effect transistor Q3 is connected to the drain of the fourth field effect transistor Q4. The gate of the fourth field effect transistor Q4 is connected to the signal output terminal of the first timing unit 1521. The source of the fourth field effect transistor Q4 is grounded. Specifically, in the embodiment shown in fig. 6, the third field effect transistor Q3 and the fourth field effect transistor Q4 are both P-channel type field effect transistors.

In some embodiments, the first switch unit 1523 further includes a first resistor R1, one end of the first resistor R1 is connected to the current input terminal, i.e., the common terminal 190, of the first lamp sub-module 1310, and the other end is connected to the gate of the third fet Q3.

The operation of the third field effect transistor Q3 and the fourth field effect transistor Q4 will be described here. When the first timing unit 1521 outputs a high level signal, the gate voltage of the fourth field effect transistor Q4 is greater than the turn-on voltage of the fourth field effect transistor Q4, the fourth field effect transistor Q4 is turned on, and the gate voltage of the third field effect transistor Q3 is pulled down, so that the third field effect transistor Q3 is turned off, and the first lamp sub-module 1310 is not turned on.

When the first timing unit 1521 outputs a low level signal, the gate voltage of the fourth field effect transistor Q4 is less than the turn-on voltage of the fourth field effect transistor Q4, and the fourth field effect transistor Q4 is not turned on. Since the gate of the third field effect transistor Q3 is connected to the electronic control module 170 through the first resistor R1, when the electronic control module 170 outputs the driving signal, the gate of the third field effect transistor Q3 is at a high level, and at this time, the third field effect transistor Q3 is turned on, so that the first vehicle lamp sub-module 1310 is turned on.

Therefore, the electronic control module 170 controls the first timing unit 1521 to output different level signals through the generated PWM signals with different specified periods, so as to control the branch circuit where the first vehicle lamp sub-module 1310 is located to be turned on or off.

Similarly, referring to fig. 4 again, the second switch module 154 includes a second timing unit 1541 and a second switch unit 1543. The second switch unit 1543 is connected to the branch of the second lamp sub-module 1330. The second timing unit 1541 is connected between the electronic control module 170 and the second switching unit 1543, and configured to output a second specified level signal to the second switching unit 1543 when the specified period is greater than the second period threshold, where the second specified level signal is used to turn on a branch where the second lamp sub-module 1330 is located.

In some embodiments, the second timing unit 1521 may be a PWM window timing circuit, an input of which is a PWM signal generated by the electronic control module 170, the PWM window timing circuit is configured to time a specified period of the PWM signal, and in a case that the specified period is greater than a second period threshold, the PWM window timing circuit outputs a second specified level signal, which is exemplarily a low level signal, an amplitude of the low level signal is less than 0.7V, for example, an amplitude of the low level signal is 0.3V. Conversely, in the case where the specified period is less than or equal to the second period threshold, the PWM window timing circuit outputs a high level signal having an amplitude greater than 3V, for example, an amplitude of 3.5V. Specifically, the PWM window timing circuit may be implemented by an electronic circuit, or may be implemented by a chip having a timing function, which is not specifically limited in this embodiment.

In some possible embodiments, the second switching unit 1543 includes a second field effect transistor Q2, and the second field effect transistor Q2 is a voltage control type semiconductor device. The drain of the second field effect transistor Q2 is connected to the current output terminal of the second lamp submodule 1330. The source of the second field effect transistor Q2 is connected to the current output terminal of the first lamp module 110 and is grounded. The gate of the second field effect transistor Q2 is connected to the signal output terminal of the second timing unit 1541. Specifically, the control logic of the second timing unit 1541 for the second field effect transistor Q2 may refer to the control logic of the first timing unit 1521 for the first field effect transistor Q1 in the foregoing embodiment, which is not described again in this embodiment.

In some possible embodiments, referring again to fig. 6, the second switching unit 1543 includes a fifth field effect transistor Q5 and a sixth field effect transistor Q6. The drain of the fifth field effect transistor Q5 is connected to the current output terminal of the second lamp submodule 1330. The source of the fifth field effect transistor Q5 is connected to the current output terminal of the first lamp module 110 and is grounded. The gate of the fifth field effect transistor Q5 is connected to the drain of the sixth field effect transistor Q6. The gate of the sixth field effect transistor Q6 is connected to the signal output terminal of the second timing unit 1541. The source of the sixth field effect transistor Q6 is grounded.

The second switch unit 1543 further includes a second resistor R2, wherein one end of the second resistor R2 is connected to the current input terminal of the second lamp sub-module 1330, and the other end is connected to the gate of the fifth field effect transistor Q5. Specifically, the control logic of the fifth field effect transistor Q5 and the sixth field effect transistor Q6 by the second timing unit 1541 may refer to the control logic of the third field effect transistor Q3 and the fourth field effect transistor Q4 by the first timing unit 1521 in the foregoing embodiment, which is not described again in this embodiment.

It should be noted here that the circuit structures of the first switch unit 1523 and the second switch unit 1543 shown in fig. 4 and fig. 6 are only schematic, and the first field effect Transistor Q1, the second field effect Transistor Q2, the third field effect Transistor Q3, the fourth field effect Transistor Q4, the fifth field effect Transistor Q5, and the sixth field effect Transistor Q6 may be replaced by other power electronic devices having a switch function, for example, bipolar Junction Transistors (BJTs), insulated Gate Bipolar Transistors (IGBTs), and the like, and the present embodiment is not limited in particular.

Wherein the collector of the bipolar transistor Q7 is connected to the current output terminal of the first vehicle lamp sub-module 1310. The emitter of the bipolar transistor Q7 is connected to the current output terminal of the first lamp module 110 and is grounded. The base of bipolar transistor Q7 is connected to the collector of bipolar transistor Q8. The base of the bipolar transistor Q8 is connected to the signal output terminal of the first timing unit 1521. The emitter of the bipolar transistor Q8 is grounded. Specifically, the bipolar transistors Q7 and Q8 may be silicon transistors, germanium transistors, or the like, and the present embodiment is not particularly limited.

The Electronic Control module 170 is connected to the first switch module 1310, the second switch module 1330, and the common terminal 190 formed by the first lamp module 110, the first lamp sub-module 1310 and the second lamp sub-module 1330, and the Electronic Control module 170 is an Electronic Control Unit (ECU) in the vehicle 200. The electronic control module 170 is connected to the first switch module 1310, the second switch module 1330 and the common terminal 190 via a vehicle-mounted hard wire.

In the embodiment shown in fig. 4, the electronic control module 170 is connected to the signal input terminal of the first timing unit 1521 in the first switch module 1310 and the signal input terminal of the second timing unit 1541 in the second switch module 1330. Specifically, the electronic control module 170 is configured to: the driving signal is output and is used for being input to the first lamp module 110 via the common terminal 190 to control the first lamp module 110 to operate in the first lighting mode, and is also used for being input to the first switch module 152 and the second switch module 154 to drive the first switch module 152 and the second switch module 154 to control at least one of the first lamp sub-module 1310 and the second lamp sub-module 1330 to operate in the second lighting mode. It should be noted that, in some embodiments, the second cycle threshold corresponding to the second timing unit 1541 is greater than the first cycle threshold corresponding to the first timing unit 1521. Therefore, the electronic control module 170 may output driving signals with different designated periods to light different lamp modules, so that the rectangular lamp bead arrays formed by the first lamp module 110, the first lamp sub-module 1310 and the second lamp sub-module 1330 display different lighting patterns.

The following describes the patterns displayed by the rectangular bead array with reference to the embodiment of fig. 6 and fig. 7 to 9.

Referring to fig. 7, as shown in fig. 7 (a), when the specified period of the driving signal is greater than the first period threshold and the specified period is greater than the second period threshold, both the first timing unit 1521 and the second timing unit 1541 output low level signals. The fourth field effect transistor Q4 and the sixth field effect transistor Q6 are not turned on, and the third field effect transistor Q3 and the fifth field effect transistor Q5 are turned on. In this case, when the first lamp module 110 enters the first lighting mode and the first and

second lamp sub-modules

1310 and 1330 enter the second lighting mode, the first lamp module 110, the first lamp sub-module 1310 and the second lamp sub-module 1330 are all lit. At this time, the first pattern of the rectangular lamp bead array formed by the first lamp module 110, the first lamp sub-module 1310 and the second lamp sub-module 1330 is as shown in fig. 7 (b).

Referring to fig. 8, as shown in (a) of fig. 8, when the designated period of the driving signal is greater than the first period threshold and the designated period is less than or equal to the second period threshold, at this time, the first timing unit 1521 outputs a low level signal, and the second timing unit 1541 outputs a high level signal. The fourth field effect transistor Q4 and the fifth field effect transistor Q5 are not turned on, and the third field effect transistor Q3 and the sixth field effect transistor Q6 are turned on. In this case, when the first lamp module 110 enters the first lighting mode, the first lamp sub-module 1310 and the second lamp sub-module 1330 enter the second lighting mode, the first lamp module 110 and the first lamp sub-module 1310 are lighted, and the second lamp sub-module 1330 is not lighted. At this time, the second pattern of the rectangular lamp bead array formed by the first lamp module 110, the first lamp sub-module 1310 and the second lamp sub-module 1330 is as shown in fig. 8 (b).

Referring to fig. 9, as shown in (a) of fig. 9, when the specified period of the driving signal is less than or equal to the first period threshold and the specified period is less than or equal to the second period threshold, both the first timing unit 1521 and the second timing unit 1541 output high level signals. The fourth field effect transistor Q4 and the sixth field effect transistor Q6 are conductive, and the third field effect transistor Q3 and the fifth field effect transistor Q5 are non-conductive. In the case of this situation, it is,

when the first lamp module 110 enters the first lighting mode and the first and

second lamp sub-modules

1310 and 1330 enter the second lighting mode, the first lamp module 110 is lit and the first and

second lamp sub-modules

1310 and 1330 are not lit. At this time, the third pattern of the rectangular lamp bead array formed by the first lamp module 110, the first lamp sub-module 1310 and the second lamp sub-module 1330 is as shown in fig. 9 (b).

Therefore, the electronic control module 170 may cause the vehicle lamp control system 100 to enter different lighting modes by adjusting the specified period. For example, the electronic control module 170 may adjust the designated period to continuously switch the pattern of the rectangular lamp bead array formed by the first lamp module 110, the first lamp sub-module 1310 and the second lamp sub-module 1330 between the second pattern and the third pattern, so that the first lamp sub-module 1310 is in a flashing state, thereby enriching the display effect of the lamp in the lamp control system 100.

In some embodiments, the vehicle light control system 100 further includes a signal sampling module 180, and a signal input terminal of the signal sampling module 180 is connected to the common terminal 190, that is, connected to the electronic control module 170, and is configured to sample the driving signal output by the electronic control module 170. The signal output terminal of the signal sampling module 180 is connected to the signal input terminals of the first timing unit 1521 and the second timing unit 1541, respectively.

Specifically, the signal sampling module 180 is capable of receiving a control instruction sent by the electronic control module 170, sampling a driving signal generated by the electronic control module 170 when the control instruction is received, and sending the sampled signal to the first timing unit 1521 and the second timing unit 1541 respectively, so that the first timing unit 1521 and the second timing unit 1541 enter a timing state. Accordingly, the signal sampling module 180 can be used to control the first timing unit 1521 and the second timing unit 1541. In the embodiment shown in fig. 6, when the signal sampling module 180 has not received the control command, the driving signals generated by the electronic control module 170 cannot be output to the first timing unit 1521 and the second timing unit 1541, the fourth field effect transistor Q4 and the sixth field effect transistor Q6 are not turned on, and the third field effect transistor Q3 and the fifth field effect transistor Q5 are turned on. At this time, if the driving signal is generated by the electronic control module 170, the driving signal can directly enable the first lamp module 110, the first lamp sub-module 1310 and the second lamp sub-module 1330 to enter the lighting state. Specifically, the signal sampling module 180 may be implemented by an electronic circuit, or may be implemented by a chip having a signal sampling function, which is not specifically limited in this embodiment.
