Description

Technical Field

[0001] The present application relates to the technical field of vehicle lighting control, and in particular to a method and device for processing vehicle lighting failure, an electronic device and a storage medium. Background Art

[0002] In existing automotive lighting control systems, two strategies are usually used to handle lighting failures: one is to report a failure when a single LED (Light Emitting Diode) lamp bead fails to light up, and the other is to report a failure only when all lighting areas fail to light up. However, both methods have certain limitations.

[0003] First, regarding the strategy of reporting a fault when a single LED is not lit, since the number of LED lamp beads managed by the vehicle lighting control system is huge, close to a thousand, some of which have a low degree of participation in the vehicle lighting pattern and have limited impact on the overall lighting effect. Therefore, if a fault report is triggered only because a single LED is not lit, it may lead to unnecessary fault reports for those LED lamp beads with low perception, thereby amplifying the severity of the problem. Secondly, regarding the strategy of reporting a fault only when all lighting areas are not lit as a whole, the system will not issue a fault report when a single lighting area is not lit. However, the non-lighting of a single lighting area has a significant impact on the overall effect of the vehicle lighting, and may even cause the driver to violate traffic regulations. This strategy fails to identify and report local faults in a timely manner, which may lead to safety hazards.

[0004] Therefore, the vehicle field urgently needs a method for handling vehicle lighting faults that does not report when a single lamp bead is not lit, but can immediately report the fault when a single lighting area is not lit, so as to solve the deficiencies in the existing technology.

[0049] In order to make the above-mentioned objects, features and advantages of the present application more obvious and easy to understand, the present application is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0050] Reference Figure 1 , is a flowchart of an embodiment of a method for handling a vehicle lighting failure of the present application, comprising the following steps:

[0051] Step 101: Receive light control data sent by the controller, where the light control data is used to update the vehicle light status.

[0052] A method for handling vehicle lighting failure provided in an embodiment of the present application is applied to a vehicle lighting control system, which includes a controller and several control chips. In one example, the vehicle lighting control system may include 5 to 6 control chips. These control chips are connected in a daisy chain according to a preset connection sequence, and communicate in an SPI (Serial Peripheral Interface, a synchronous serial communication interface) daisy chain communication structure. There is a connection between the controller and the first chip and the last chip of the several control chips connected in a preset connection sequence, that is, there is a connection between the controller and the first control chip, and between the controller and the last chip.

[0053] In an optional embodiment, the vehicle lights can be divided into several lighting areas, and each control chip controls the vehicle lights of one lighting area. These lighting areas are composed of several LED lamp beads, and the control chip actually controls all LED lamp beads in the corresponding lighting area.

[0054] Reference Figure 2 , is a schematic diagram of the lighting area of ​​an embodiment of a method for handling vehicle lighting failure of the present application.

[0055] like Figure 2 As shown, Figure 2 This is a simplified schematic diagram of the lighting area of ​​a vehicle light. The vehicle light consists of five lighting areas, namely, area 1, area 2, area 3, area 4, and area 5. Correspondingly, each area contains a number of LED lamp beads. Those skilled in the art should know that Figure 2 The number of LED lamp beads shown in the figure is only a simplified expression. The actual number of LED lamp beads is generally more than Figure 2 In this embodiment, the five light zones are controlled by five control chips respectively. In one example, the five control chips are IC1 to IC5. The first IC1 is connected to the controller, and the IC1 to IC5 are connected in daisy chain in sequence, and the last IC5 is connected to the controller.

[0056] Before step 101, in one embodiment, before transmitting the light control data, the light control data required by each control chip can be synthesized into one frame of light control data. Specifically, the light control data includes the light control data required by each control chip. In one embodiment, MCU (Microcontroller Unit) software can be used to synthesize the light control data required by each control chip into one frame of light control data. For example, assuming that in the control chips IC1 to IC6, the light control data required by each control chip are D1, D2, D3, D4, D5, and D6, respectively, and the size is 769 bits, then after synthesis, the light control data is D1_D2_D3_D4_D5_D6, and the size is 769*6 bits.

[0057] In step 101, light control data sent by the controller is received, and the light control data is used to update the vehicle light state. In an optional embodiment, the light control instruction sent by the controller is received by the head chip. In another optional embodiment, the light control data includes light control data corresponding to different light areas, and the light control data is composed of light brightness data and other parameter data. The control chip can use the corresponding light control data to control the corresponding light control area.

[0058] Step 102: transmitting the light control data to the control chip one by one according to the preset connection sequence, so that the control chip updates the vehicle lights of the corresponding light area according to the light control data.

[0059] In step 102, the light control data is transmitted to the control chip one by one according to the preset connection sequence. After the control chip receives the data of the corresponding light area, it uses the light control data to update the vehicle light of the corresponding light area. For example, if the control chips are connected in the order of IC1 to IC5, the transmission order of the light control data is IC1, IC2, IC3, IC4, IC5.

[0060] In an optional embodiment, when the light control data is transmitted to the current control chip, after the current control chip receives the light control data, the light control data required by the current control chip is screened out, so that the current control chip receives the corresponding light control data. If the current control chip is not the tail chip, after receiving the data, all the light control data will continue to be transmitted to the next control chip in sequence. For example, when the light control data D1-D5 are transmitted to the control chip IC3, after the control chip IC3 receives the corresponding light control data D3, the light control data D1-D5 will continue to be transmitted to the next control chip IC4.

[0061] Step 103: after the transmission is completed, receiving instruction receiving data, the instruction receiving data is generated according to the lighting control data transmitted to the controller by the tail chip.

[0062] In step 103, after the transmission is completed, that is, after all control chips have received the corresponding light control data, the controller can receive the light control data returned to the controller by the tail chip, and generate instruction receiving data according to the light control data. That is, the acquired instruction receiving data is generated by the light control data that the last tail chip can transmit to the controller.

[0063] Step 104: Compare the instruction receiving data with the lighting control data to obtain a comparison result.

[0064] In step 104, the instruction reception data generated by the lighting control data transmitted by the tail chip received by the controller is compared with the lighting control data sent by the controller to the head chip to obtain a comparison result, thereby determining whether there is a fault in the daisy-chain control chip connection line based on the comparison result.

[0065] In one embodiment, since during a lighting update process, in the absence of any faults, each control chip can receive the corresponding lighting control data, the lighting control data transmitted from the tail chip to the controller should also be complete and the same as the lighting control data of this lighting update, that is, during the same lighting update, the instruction reception data and the lighting control data are normally the same.

[0066] Therefore, the instruction receiving data can be compared with the light control data. If the instruction receiving data is inconsistent with the light control data, it can be determined that the vehicle light is faulty.

[0067] In an example, assuming that in the control chips IC1~IC6, the light control data required by each control chip are D1, D2, D3, D4, D5, D6, and the size is 769 bits, then all the light control data are D1_D2_D3_D4_D5_D6, and the size is 769*6 bits. When the connection is normal, each control chip can receive the corresponding light control data and transmit the light control data to the next control chip. Therefore, the instruction reception data generated according to the light control data transmitted from the tail chip to the controller should be D1_D2_D3_D4_D5_D6, and the size is also 769*6bit, which is consistent with the light control data; in the case of connection problems, for example, if the light update is the first light update, that is, there is no light control data in each control chip before the update, and the connection between IC3 and IC4 is disconnected, then IC4 cannot receive the light control data transmitted by IC3, and the light area corresponding to IC4 fails. Therefore, the tail chip IC6 cannot receive the light control data, and the generated abnormal instruction reception data is 00_00_00_00_00_00, which is inconsistent with the light control data. It can be judged that there is a vehicle light failure in at least one light area.

[0068] In one embodiment, if the control chip already has the last updated light control data before this update, the control chip that cannot receive the new light control data will return the last light control data, which will also cause the instruction receiving data generated according to the light control data transmitted to the controller by the tail chip to be different from the light control data updated this time, and it is determined that at least one light area has a vehicle light failure. For example, if the last light update data is D1_D2_D3_D4_D5_D6, when D1_D2_D3_D4_D5_D6 is updated this time, the connection between IC3 and IC4 is disconnected, then IC4 cannot receive the light control data transmitted by IC3, and the light area corresponding to IC4 fails, so the tail chip IC6 cannot receive the light control data, and the generated abnormal instruction receiving data is 00_00_00_D4_D5_D6, which is inconsistent with the current light control data D1_D2_D3_D4_D5_D6, and it can be determined that at least one light area has a vehicle light failure.

[0069] In this embodiment, since the control chips are connected in a daisy chain, as long as a connection of a control chip somewhere fails, the lighting area corresponding to the next control chip at the failed location will fail. At this time, by comparing the instruction received data with the lighting control data, it can be known that the connection has failed, thereby realizing fault perception of a single lighting area.

[0070] Step 105: Determine a fault determination result of the vehicle lighting fault according to the comparison result.

[0071] In step 105, a fault determination result of the vehicle light fault may be further determined based on the comparison result, that is, the specific connection position where the fault occurs may be determined.

[0072] In one embodiment, if the fault location cannot be determined directly by comparing the command receiving data with the light control data, preset light control data for testing may be sent to the daisy chain to determine the fault location.

[0073] In one embodiment, after confirming that a vehicle lighting fault occurs, the vehicle lighting fault is reported to the vehicle control system so that the vehicle control system records fault information corresponding to the vehicle lighting fault, namely DTC (Diagnostic Trouble Codes, reporting faults and recording diagnostic trouble codes).

[0074] In the embodiment of the present application, the light control data sent by the controller is received, and the light control data is used to update the vehicle light status; the light control data is transmitted to the control chip one by one according to the preset connection order, so that the control chip updates the vehicle light of the corresponding light area according to the light control data; after the transmission is completed, the instruction reception data is received, and the instruction reception data is generated according to the light control data transmitted to the controller by the tail chip; the instruction reception data is compared with the light control data to obtain a comparison result; and the fault judgment result of the vehicle light fault is determined according to the comparison result. The embodiment of the present application adopts a daisy chain control chip connection and communication method, and judges whether there is a fault by comparing the instruction reception data returned by the tail chip with the original light control data. When a single light area is not lit, it can be immediately identified and notified to the technician through fault reporting, so as to avoid affecting the normal lighting effect of the vehicle due to light failure in all light areas, and also avoid unnecessary waste of resources caused by reporting when a single lamp bead is not lit, so as to achieve more effective processing of vehicle light faults and ensure the safety and compliance of vehicle driving.

[0075] In an optional embodiment of the present application, determining the fault determination result of the vehicle lighting fault according to the comparison result includes:

[0076] If the command receiving data is inconsistent with the light control data, the fault position in the daisy chain is determined according to the light control data and the command receiving data.

[0077] In this embodiment, if the command receiving data is inconsistent with the light control data, it can be determined that the vehicle light is faulty, and the specific connection where the fault occurs can be determined by comparing the command receiving data with the light control data. If the fault location cannot be determined directly based on the comparison result between the command receiving data and the light control data, preset test light control data can be further sent to the daisy chain, and the command receiving data obtained by the test can be compared with the test light control data to determine the fault location.

[0078] The embodiment of the present application can determine that the vehicle lighting is faulty when the command receiving data is inconsistent with the lighting control data, so that when a single lighting area does not light up, it can be immediately identified and the technician can be notified through a fault report.

[0079] In an optional embodiment of the present application, the determining the fault location in the daisy chain according to the lighting control data and the command receiving data includes:

[0080] If the lighting control data is all-zero data, and the instruction receiving data is not all-zero data, it is determined that there is a fault in the connection between the controller and the head chip;

[0081] If the lighting control data contains non-zero data for each of the control chips, and the instruction receiving data is all zero data, it is determined that there is a fault in the connection between the controller and the tail chip.

[0082] In this embodiment, if the light control data is all zero data and the command receiving data is not all zero data, it is determined that there is a fault in the connection between the controller and the head chip. In one embodiment, the light control data can be the light control data updated this time, or it can be the light control data for testing transmitted to specifically determine the fault location.

[0083] For example, if the link contains 1 controller MCU and 6 control chips IC1~IC6, when the data link in the daisy chain is disconnected at MCU->IC1, the disconnection here will cause all control chips to be unable to receive the data updated by the MCU this time. The control chip retains the light control data of the last update before the disconnection. When the light control data to be updated in the link is all zero data 00-00-00-00-00-00, since the data stored in IC1~IC6 is the data D1-D2-D3-D4-D5-D6 before the disconnection and cannot receive new light control data, the command reception data obtained in this update is D1-D2-D3-D4-D5-D6. Therefore, it can be judged that the command reception data obtained in this update is not all 0, and the disconnection position is the break between the MCU and the first control chip.

[0084] In this embodiment, if the light control data has non-zero data for each control chip, and the instruction receiving data is all zero data, it is determined that there is a fault in the connection between the controller and the tail chip. In one embodiment, the light control data can be the light control data updated this time, or it can be the light control data for testing transmitted to specifically determine the fault location.

[0085] For example, if the link contains 1 controller MCU and 6 control chips IC1~IC6, when the data link in the daisy chain is disconnected at IC6->MCU, although all control chips can be updated to the new light control data, the MCU cannot receive the new light control data returned by IC6, so the generated instruction reception data is all-zero data 00-00-00-00-00-00. At this time, if the updated graphic data is D1-D2-D3-D4-D5-D6, the disconnection position can be judged as the connection between the MCU and the last chip through the instruction reception data being all 0.

[0086] The embodiment of the present application can further confirm the fault location of the daisy chain by comparing the command reception data with the light control data, thereby achieving more effective processing of vehicle light faults.

[0087] In an optional embodiment of the present application, the determining the fault location in the daisy chain according to the lighting control data and the command receiving data includes:

[0088] If the light control data is different from the last light control data, and the last light control data and the light control data have non-zero data for each control chip, the fault position in the daisy chain is determined according to the instruction reception data.

[0089] In this embodiment, if it is necessary to determine the fault position of the connection between the control chips, the fault position in the daisy chain can be determined according to the instruction receiving data when the lighting control data is different from the previous lighting control data and the previous lighting control data and the lighting control data have non-zero data for each control chip. In one embodiment, the lighting control data can be the lighting control data updated this time, or it can be the lighting control data for testing transmitted to specifically determine the fault position.

[0090] For example, if the link contains 1 controller MCU and 6 control chips IC1~IC6, when the data link in the daisy chain is disconnected at ICx->ICy, the disconnection here will cause the control chip in front of the disconnection position to update the data, but it cannot transmit the updated light control data to ICy and the control chips after it. Therefore, the control chip behind the disconnection position cannot update the data, but the control chip behind the disconnection position still saves the last light control data. If the last light control data is X1-X2-X3-X4-X5-X6, the updated data this time is Y1-Y2-Y3-Y4-Y5-Y6, if the disconnection position is between the third and fourth control chips, the command received data that can be obtained is 00-00-00-X4-X5-X6, and the position of the zero data can be determined based on the command received data, so that the position at X3->X4 is the disconnection position.

[0091] The embodiment of the present application can further confirm the fault location of the daisy chain by comparing the command reception data with the light control data, thereby achieving more effective processing of vehicle light faults.

[0092] In an optional embodiment of the present application, transmitting the lighting control data to the control chip one by one according to the preset connection sequence includes:

[0093] When the light control data is transmitted to the current control chip, after controlling the current control chip to receive the light control data, the light control data required by the current control chip is screened out from the light control data;

[0094] If the current control chip is not the tail chip, after the current control chip receives the light control data required by the current control chip, the light control data is transmitted to the next control chip according to the preset connection sequence;

[0095] According to the light control data required by the current control chip, the vehicle light state of the light area corresponding to the current control chip is updated.

[0096] In this embodiment, when the light control instruction is transmitted to the current control chip, after the current control chip receives the light control data, the light control data required by the current control chip is screened out, and the light control data required by the current control chip is collected. If the current control chip is not the tail chip, after receiving the data, the light control data is transmitted to the next control chip in a preset connection sequence, so that the next control chip performs the same steps. For example, if the light control data is transmitted to the current control chip IC3, and the light control data is D1_D2_D3_D4_D5_D6, then after IC3 screens and receives the light control data D3, it transmits the light control data to the next control chip IC4.

[0097] After the current control chip receives the light control data required by the control chip, the vehicle light state of the light area corresponding to the current control chip is updated according to the light control data required by the current control chip. In one example, the parameters such as the brightness of the LED lamp beads and the lighting pattern of the light area can be updated according to the light control data.

[0098] The embodiment of the present application transmits lighting control data in sequence on a daisy chain connection structure, so that when a connection fails somewhere, that is, when a lighting area fails, the fault can be identified immediately.

[0099] In an optional embodiment of the present application, each of the control chips includes a serial input terminal and a serial output terminal, and the serial output terminal of each of the control chips except the tail chip is connected to the serial input terminal of the next control chip, and the light control data is transmitted to the control chips one by one according to the preset connection sequence, including:

[0100] When the light control data is transmitted to the serial input terminal of the current control chip, after controlling the current control chip to receive the light control data, the light control data required by the current control chip is screened out from the light control data;

[0101] receiving a latch signal sent by the controller;

[0102] According to the latch signal, controlling the current control chip to receive the lighting control data required by the current control chip;

[0103] If the current control chip is not the tail chip, the light control data is transmitted to the serial output end of the next control chip according to the preset connection sequence.

[0104] In this embodiment, each control chip includes a serial input terminal and a serial output terminal. The serial output terminal of each control chip except the tail chip is connected to the serial input terminal of the next control chip. The serial input terminal is used to receive lighting control instructions, and the serial output terminal is used to send lighting control instructions to the next control chip; for the tail chip, the serial output terminal is used to send instructions to the controller to receive data.

[0105] Specifically, when the light control data is transmitted to the serial input terminal of the current control chip, the current control chip will receive the light control data and filter out the light control data required by the current control chip. At this time, the controller will generate a latch signal. After the current control chip receives the latch signal sent by the controller, it will receive the light control data required by the current control chip according to the latch signal. After receiving the light control data, if the current control chip is not the last chip, the light control data will be transmitted to the serial output terminal of the next control chip according to the preset connection sequence.

[0106] The embodiment of the present application connects the control chips in a daisy chain according to a preset connection sequence and communicates in an SPI daisy chain communication structure, so that when a connection fails somewhere, that is, when a lighting area fails, the fault can be immediately identified.

[0107] In an optional embodiment of the present application, the serial input end of the head chip is connected to the controller, the serial output end of the tail chip is connected to the controller, and the receiving of the lighting control data sent by the controller includes:

[0108] Receiving the lighting control data sent by the controller through the serial input terminal of the head chip;

[0109] After controlling the current control chip to collect the lighting control data required by the current control chip, the method further includes:

[0110] If the current control chip is the tail chip, the light control data is returned to the controller through the serial output terminal of the tail chip, so that the controller generates the instruction receiving data according to the received light control data.

[0111] In this embodiment, the serial input end of the head chip is connected to the controller, and the serial output end of the tail chip is connected to the controller. For the head chip, it is necessary to receive the light control data sent by the controller through the serial input end of the head chip; for the tail chip, after receiving the corresponding light control data, it is necessary to return the light control data to the controller through the serial output end of the tail chip, so that the controller generates an instruction to receive data according to the received light control data.

[0112] The embodiment of the present application connects the head chip and the tail chip to the controller respectively, completes the reception of light control data and the return of command reception data, and can further realize the judgment of vehicle light failure.

[0113] In an optional embodiment of the present application, the method may further include:

[0114] Comparing the instruction receiving data with the lighting control data in the lighting control instruction for data integrity, and if the instruction receiving data is inconsistent with the lighting control data, updating the number of communication anomalies;

[0115] When the number of communication anomalies reaches a preset number, it is determined to be a vehicle light failure.

[0116] In this embodiment, in order to reduce the probability of misjudgment, the vehicle lighting failure is determined only when the command receiving data and the lighting control data are found to be inconsistent for multiple times. Specifically, the command receiving data and the lighting control data are compared for data integrity. If the command receiving data and the lighting control data are inconsistent, the number of communication anomalies is updated. When the number of communication anomalies reaches a preset number, it is determined that the vehicle lighting failure occurs.

[0117] The embodiment of the present application determines that the vehicle lighting failure occurs only when the number of communication anomalies reaches a preset number, which can reduce the probability of misjudgment. At the same time, it can also ensure that the normal lighting effect of the vehicle is not affected by the lighting failure, thereby achieving more sensitive and effective processing of the vehicle lighting failure.

[0118] In the embodiment of the present application, the light control data sent by the controller is received, and the light control data is used to update the vehicle light status; the light control data is transmitted to the control chip one by one according to the preset connection order, so that the control chip updates the vehicle light of the corresponding light area according to the light control data; after the transmission is completed, the instruction reception data is received, and the instruction reception data is generated according to the light control data transmitted to the controller by the tail chip; the instruction reception data is compared with the light control data to obtain a comparison result; and the fault judgment result of the vehicle light fault is determined according to the comparison result. The embodiment of the present application adopts a daisy chain control chip connection and communication method, and judges whether there is a fault by comparing the instruction reception data returned by the tail chip with the original light control data. When a single light area is not lit, it can be immediately identified and notified to the technician through fault reporting, so as to avoid affecting the normal lighting effect of the vehicle due to light failure in all light areas, and also avoid unnecessary waste of resources caused by reporting when a single lamp bead is not lit, so as to achieve more effective processing of vehicle light faults and ensure the safety and compliance of vehicle driving.

[0119] The following will combine Figure 3 and Figure 4 , a vehicle lighting failure processing method and a vehicle lighting control system provided in an embodiment of the present application are described in detail so that those skilled in the art can better understand the contents of the embodiment of the present application.

[0120] Reference Figure 3 , is a schematic diagram of the control chip structure of an embodiment of a method for processing vehicle lighting failure of the present application.

[0121] like Figure 3 As shown, Figure 3 The structure of a control chip that can be used in the embodiment of the present application is shown in FIG. Among them, the OUTB0~OUTB15, OUTG0~OUTG15, OUTR0~OUTR15 pins are used to connect LED lamp beads; Thermal pad is a thermal pad; GND is a ground terminal; GSCLK is a global system clock signal; SCLK is a synchronous clock; V CC is the power supply; LAT is the latch signal; SIN is the serial input terminal; SOUT is the serial output terminal, etc.

[0122] SIN is used to connect the previous control chip or controller, and SOUT is used to connect the next control chip or controller. If the connection between the SIN pin and the previous control chip or controller fails, the control chip cannot receive new light control data.

[0123] Reference Figure 4 , is a system structure diagram of an embodiment of a method for processing vehicle lighting failure of the present application.

[0124] like Figure 4 As shown in the figure, the vehicle lighting control system includes multiple control chips, a controller and multiple LED lamp beads. Only the first chip and the last chip are shown in the figure, and the rest of the chips are omitted. Figure 4 The control chip includes SIN (serial input), SOUT (serial output), SCLK (synchronous clock), LAT (latch signal), GSCLK (global system clock signal), V CC (power), GND (ground) and other ports, OUTR0~OUTB15 on each control chip are connected to control the corresponding 48 LED lamp beads, and the LED lamp beads are further connected to the corresponding power supply V LED connect.

[0125] In the vehicle lighting control system, the Controller's output port DATA is connected to the SIN of the first chip, the SOUT of the first chip is connected to the SIN of the next control chip, and so on, the SOUT of the second-to-last control chip is connected to the SIN of the tail chip, and the SIN of the tail chip is connected to the fault judgment port (Error Read) of the Controller. The SCLK, LAT, and GSCLK of all control chips are connected in parallel to the corresponding ports of the Controller.

[0126] Assuming that the system has control chips IC1~IC6, then Figure 4 The head chip is IC1 and the tail chip is IC6. In this example, it is assumed that the line between IC5 (not shown in the figure) and IC6 is physically disconnected, resulting in the loss of communication of the tail chip IC6 of the daisy chain structure.

[0127] First, the controller determines that the light control data required by each control chip are D1, D2, D3, D4, D5, and D6, each of which is 769 bits in size. These light control data are synthesized to obtain light control data D1_D2_D3_D4_D5_D6, which is 769*6 bits in size and sent to IC1. After the serial input end of IC1 receives the light control data, it filters out the 769-bit light control data required by IC1 in the light control data. At this time, the controller generates a latch signal. After IC1 receives the latch signal, it will receive the light control data required by IC1 according to the latch signal. After receiving the light control data, the light control data is transmitted to the serial output end of IC2 in the preset connection order, and so on, until the light control data passes through the line disconnection point between IC5 and IC6.

[0128] At this time, IC6 cannot receive the light control data, and therefore cannot transmit the light control data to the controller normally. Therefore, the Controller can only generate abnormal command reception data of 00_00_00_00_00_00. The Controller compares the command reception data with the initial light control data, and after finding inconsistencies, it updates the number of communication anomalies. When the number of communication anomalies reaches the preset number, it is determined to be a vehicle light failure, and the vehicle light failure is reported to the vehicle control system.

[0129] In the embodiment of the present application, the light control data sent by the controller is received, and the light control data is used to update the vehicle light status; the light control data is transmitted to the control chip one by one according to the preset connection order, so that the control chip updates the vehicle light of the corresponding light area according to the light control data; after the transmission is completed, the instruction reception data is received, and the instruction reception data is generated according to the light control data transmitted to the controller by the tail chip; the instruction reception data is compared with the light control data to obtain a comparison result; and the fault judgment result of the vehicle light fault is determined according to the comparison result. The embodiment of the present application adopts a daisy chain control chip connection and communication method, and judges whether there is a fault by comparing the instruction reception data returned by the tail chip with the original light control data. When a single light area is not lit, it can be immediately identified and notified to the technician through fault reporting, so as to avoid affecting the normal lighting effect of the vehicle due to light failure in all light areas, and also avoid unnecessary waste of resources caused by reporting when a single lamp bead is not lit, so as to achieve more effective processing of vehicle light faults and ensure the safety and compliance of vehicle driving.
