[0028] Embodiment 1

[0029] Figure 1 A flowchart of a lamp control method is provided for the first embodiment of the present invention. This embodiment is applicable to controlling lamps. The method can be executed by a lamp control device. The lamp control device can be implemented in the form of hardware and / or software. The lamp control device can be configured in a vehicle. Figure 1 As shown, the method includes:

[0030] S110, generating control data corresponding to at least one type of controlled lamps according to a user control instruction.

[0031] Among them, the user control instruction can be an instruction for the user to control the vehicle to operate the lamps. The specific form of the user control instruction can be a language instruction, a button operation instruction, a screen touch instruction, etc.; the controlled lamps can be different types of signal lights configured in the vehicle, for example, they can include position lights, turn signals, reversing lights, brake lights, etc., and the control data of different types of signal lights can be the same or different; the control data can refer to the data for controlling the state of the lamp generated according to the user control instruction. The control data can be of multiple types, and different control data can control different lamp states. The control data can be encapsulated in one or more message transmissions, wherein the type of message may not be limited here, such as an integrated circuit bus message, an Internet Protocol (IP) message, etc.; the lamp state can refer to the lamp display form, which can include the lamp being lit, the lamp being turned off, the lamp being lit in a sequential manner, etc.

[0032] Specifically, the vehicle can obtain the user control instruction triggered by the user through a button or a visual interface, and generate control data corresponding to the controlled lamps according to the user control instruction. Specifically, the control data can be generated after the vehicle microcontroller unit (MCU) performs signal processing on the user control instruction. Different user instructions can correspond to different control data. When the user triggers different user control instructions through a button or a visual interface, corresponding different control data will be generated. For example, when the user triggers the position lights and brake lights to light up through a button or a visual interface, the MCU will perform signal processing on the user control instruction and generate control data corresponding to the control of the position lights and brake lights to light up, wherein the control data can be encapsulated in one or more message transmissions.

[0033] S120, sending control data to a driver chip of the controlled lamp based on a preset period to control the controlled lamp to execute the controlled data.

[0034] Among them, the preset cycle may refer to a preset cycle for sending control data. The vehicle end may send control data at a time length corresponding to the preset cycle. The preset cycle may be pre-configured in the vehicle system by the vehicle manufacturer based on experience; the driving chip may refer to a chip with a driving function, which can amplify the input weak current signal to be strong enough to drive the control lamp to change the display state.

[0035] Specifically, the control data can be sent to the vehicle driver chip in a periodic manner. After the MCU performs signal processing, the control data is transmitted to the driver chip through the corresponding instructions, and then the driver chip controls the controlled lamp to execute the control data sent by the vehicle. Among them, each driver chip is connected to a lamp with a corresponding function, and each driver chip can control the corresponding controlled lamp to execute the control data. For example, the driver chip can drive the lamp to light up, turn off, or light up in a running order. The preset period can be the time set by the vehicle manufacturer based on experience. For example, the preset period stored in the vehicle can be 50 milliseconds, 100 milliseconds, 300 milliseconds, etc. The preset period can also be specifically sending 100 signals within 1 second, sending 200 signals within 1 second, etc.

[0036] The embodiments of the present invention can realize stable control of the lamps by generating control data corresponding to at least one type of controlled lamps according to user control instructions, sending the control data to the driver chip of the controlled lamps according to a preset period, and then controlling the lamps through the driver chip to execute the control data generated according to the user control instructions. The periodic transmission of control data to the driver chip can ensure that the functions are accurately implemented according to the control data, avoid driver chip errors or driver chip data distortion due to external interference that lead to function failure, and improve the stability of controlling the lamps.

[0037] Embodiment 2

[0038] Figure 2 This is a flow chart of a lamp control method provided in Embodiment 2 of the present invention. This embodiment is a specific implementation based on the above embodiment. Figure 2 As shown, the method includes:

[0039] S210: Receive a user control instruction input by a user.

[0040] Furthermore, the user control instruction includes: at least one of a touch instruction, a voice instruction, and a gesture instruction.

[0041] Among them, the touch command can be an instruction command for the user to control the signal light by clicking the touch screen configured in the car; the voice command can be an instruction command for the user to control the signal light through voice signals; the gesture command can be an instruction command for the user to control the signal light through different gestures. Among them, the instruction command can include multiple types, and different forms of different instructions can control different instruction commands.

[0042] In an embodiment of the present invention, a user can input a user control instruction to the vehicle to generate control data for controlling the state change of the signal lights configured in the vehicle, and the vehicle can execute the function of receiving the control data. The vehicle can receive the user control instruction in one or more ways. According to the different forms of the user control instruction, the user control instruction can be received in different ways. For example, when the user control instruction is a touch click signal, the user control instruction can be received by monitoring the interactive controls in the vehicle visualization interface. The vehicle visualization interface can display multiple images, each image can correspond to a lamp. The user clicks one or more images in the visualization interface, and the vehicle can obtain the click as the user control instruction, and can use the identification information of the lamp corresponding to the clicked image as the controlled lamp identification, and can use the lamp control state corresponding to the lamp click as the control state; when the user control instruction is a voice signal, the user control instruction can be collected by a microphone provided in the vehicle, and the microphone provided in the vehicle can receive the user's voice instruction, and the corresponding A voice command package for each user control command, each voice command in the voice command package can correspond to the control state of a lamp. The user speaks one or more voice commands in the voice command package, and the vehicle can obtain the voice command as the user control command, and can use the identification information of the lamp corresponding to the voice-controlled lamp as the identification of the controlled lamp, and can use the control state of the lamp corresponding to the voice control as the control state; when the user control command is a gesture operation signal, the user control command can be collected by the camera set in the vehicle, and the camera configured in the vehicle can collect the user's gesture actions, each gesture action can correspond to a lamp, the user makes one or more gesture actions, and the vehicle can obtain the action as the user control command, and can use the identification information of the lamp corresponding to the gesture as the identification of the controlled lamp, and can use the control state of the lamp corresponding to the gesture action of the lamp as the control state.

[0043] S220: Extract the controlled lamp identification and control status included in the user control instruction.

[0044] Among them, the lamp identification may refer to the expression and indication of the lamp information, and the lamp information may include the name, type and other information of the lamp. The lamp identification may be a sign used to identify the lamp; the control state may refer to the display form of the controlled lamp, for example, it may include controlling the lamp to light up, lighting the lamp in a running sequence, turning off the lamp, etc. The method of extracting the user control instruction may not be limited here, and different methods may be used to extract the user control instruction when receiving different forms of user control instructions. The user control instruction data may be stored in a register, and the user control instruction may be read from the vehicle memory or the MCU register, and the information on the fixed field in the user instruction is extracted as the controlled lamp identification and control state.

[0045] Specifically, the MCU can extract user control instructions, which can include extracting the controlled lamp identification and control status. By extracting the lamp identification, the lamp information can be clarified and the lamp type can be determined; by extracting the control status information, the lamp display status can be clarified. Among them, the lamp types can include signal lights, turn signals, brake lights, reversing lights, etc. Different types of lamps can have different functions.

[0046] S230: Encapsulate the controlled lamp identification and control status into an integrated circuit bus message as control data.

[0047] Among them, the integrated circuit bus message refers to the data unit exchanged and transported in the integrated circuit bus communication protocol network, which is used to exchange information when requesting and responding between various systems. Different fields of the integrated circuit bus message can correspond to the control of different types of lamps, and different controlled lamp identifications and control states can be encapsulated in the same or different integrated circuit bus messages.

[0048] Specifically, the controlled lamp identification and control status can be encapsulated into an integrated circuit bus message, and the controlled lamp identification and control status can be written into different fields of the message. The integrated circuit bus message encapsulating the controlled lamp identification and control status can be used as control data. The integrated circuit bus message can encapsulate one or more sets of controlled lamp identification and control status. Different controlled lamp identifications and control status can be encapsulated in the same integrated circuit bus message. The integrated circuit bus message assumes the function of loading and transporting data, and the integrated circuit bus message can be used as lamp control data.

[0049] S240: If it is determined that the current control data is different from the historical control data transmitted last time, the control data is immediately sent to the driver chip of the controlled lamp so that the controlled lamp immediately executes the current control data.

[0050] Among them, historical control data may refer to the control data written into the driver chip last time or several times before. The historical control data may be stored in a register. The MCU may read and write the data information stored in the register. The MCU may read different values ​​of each bit of the register. The value of each bit may have different control functions, such as controlling the lighting of a lamp or lamp to turn on or off.

[0051] Specifically, the MCU can read and write data information in the register. When the MCU writes the current control data to the register, it can extract the historical control data of the previous transmission and compare it with the current control data. When it is determined that the current control data is different from the historical control data transmitted last time, the current control data can be immediately sent to the driver chip corresponding to the controlled lamp. The driver chip drives the controlled lamp to immediately execute the current control data, and the controlled lamp can immediately change the display status according to the control data.

[0052] S250 , transmitting control data to the driving chip according to the integrated circuit bus communication protocol in each preset cycle.

[0053] Among them, the integrated circuit bus communication protocol is a serial communication bus that uses a multi-master-slave architecture. The integrated circuit bus (Inter-Integrated Circuit, IIC) serial bus generally has two signal lines, one is the bidirectional IIC bus data signal line (Serial Date, SDA), and the other is the clock signal line (Serial clock line, SCL). All serial data SDA connected to the IIC bus devices are connected to the bus SDA, and the clock line SCL of each device is connected to the bus SCL, such as driver chips, MCUs, etc.

[0054] Specifically, the CAN signal at the vehicle end drives the chip to transmit control data according to the preset cycle. The same control data can be transmitted to the driver chip at regular intervals until the MCU generates new control data. Communication transmission can be carried out according to the integrated circuit bus communication protocol. When SCL is at a high level, SDA jumps from a high level to a low level and starts to transmit control data. Among them, the preset cycle can be the time set by the vehicle manufacturer based on experience. For example, the preset cycle stored in the vehicle can be 50 milliseconds, 100 milliseconds, 300 milliseconds, etc. The preset cycle can also be specifically sending 100 signals within 1 second, sending 200 signals within 1 second, etc.

[0055] S260: The control driving chip extracts the control state in the control data according to the controlled lamp identifier of the controlled lamp driven by the control driving chip.

[0056] Specifically, the control data may be control data of multiple controlled lamps. After acquiring the control data, the driver chip may search for the corresponding control state in the control data according to the controlled lamp identification. The driver chip may identify and extract the corresponding field of the integrated circuit bus message in the control data. The driver chip may identify the message field corresponding to the controlled lamp identification driven by it in the control data, and extract the control state of the controlled lamp sent by the MCU according to the controlled lamp identification. The control state may be the lamp on, the lamp off, etc.

[0057] S270, controlling the driving chip to drive the controlled lamp to work according to the control state and the current state of the lamp.

[0058] Specifically, the driver chip can drive the controlled lamp to work, and determine whether to change the working state of the lamp according to the relationship between the control state and the current state of the lamp. The control state and the current state of the lamp can be the same or different. When the control state and the current state of the lamp are the same, the driver chip can control the controlled lamp to maintain the current working state; when the control state and the current state of the lamp are different, the driver chip can control the controlled lamp to change to the working state in the control state.

[0059] S280: Obtain feedback information of the control data corresponding to the driver chip, and detect lamp control failure according to the feedback information.

[0060] Among them, feedback information may refer to status information fed back by the driver chip, or may refer to information received by the driver chip when feeding back control data to the MCU. The status information may identify the execution status of the control data. When the MCU sends control data to the driver chip to drive the controlled lamp to work, the driver chip will send feedback information to the MCU, and may be used to detect lamp control faults. Control faults may refer to faults caused by the lamp failing to execute control data normally. Control faults may be divided into communication faults, lamp faults, etc. according to their types.

[0061] Specifically, the driver chip can realize the transmission and execution of control data between the driver MCU and the lamp. The MCU sends the control data and processes it. When the lamp correctly executes the information instruction corresponding to the transmitted data, the driver chip needs to transmit feedback information to the MCU. The MCU can read the data in the driver chip register and read different values ​​for each bit. The value of each bit can correspond to different functions, and the fault is judged according to the feedback information. If the MCU sends control data to the driver chip but does not receive feedback information from the driver chip, it can be judged as a communication failure; if the working status of the lamp in the feedback information is not executed according to the control data, it can be judged as a lamp failure.

[0062] The embodiments of the present invention can establish a corresponding execution relationship between the lamp and the control data by extracting the lamp identification and control status in the user control instruction, and encapsulating the controlled lamp identification and control status into an integrated circuit bus message as control data. By transmitting the control data to the driver chip according to the integrated circuit bus communication protocol within each preset cycle, the driver chip is controlled to extract the control status in the control data according to the controlled lamp identification of the controlled lamp driven by it, so that the lamp function can be accurately executed according to the control data. By obtaining the feedback information of the corresponding control data of the driver chip and detecting the lamp control fault according to the feedback information, the lamp function can be monitored and diagnosed, and different types of fault information can be discovered in time, thereby ensuring driving safety and improving the user experience.

[0063] Furthermore, the control driving chip drives the controlled lamp to work according to the control state and the current state of the lamp, including:

[0064] The control driver chip maintains the working state of the controlled lamp when the control state is the same as the current state of the lamp.

[0065] The control driving chip changes the working state of the controlled lamp to the control state when the control state is different from the current state of the lamp.

[0066] Specifically, the control state and the current state of the lamp can be the same or different, and the control chip can drive the controlled lamp to work according to the control state and the current state of the lamp. According to the relationship between the control state and the current state of the lamp, the controlled lamp can maintain the original working state or change the working state. When the control state is the same as the current state of the lamp, the driver chip can control the controlled lamp to maintain the working state; when the control state is different from the state of the lamp, the driver chip can control the controlled lamp to change the working state to the control state.

[0067] Further, obtaining feedback information of the control data corresponding to the driver chip, and detecting the lamp control fault according to the feedback information, including:

[0068] Receive feedback information from the driver chip regarding control data.

[0069] When the feedback information includes lamp fault information, it is determined that the lamp control fault is a lamp fault.

[0070] When the feedback information includes communication fault information, it is determined that the lamp control fault is a communication fault.

[0071] Specifically, the MCU can read and receive feedback information from the driver for control data, and different control data can provide different feedback information. The feedback information may include lamp fault information, communication fault information, etc. A lamp control fault may be a fault caused by the lamp not executing the control data normally. The control fault may be divided into communication fault, lamp fault, etc. according to the type. When the feedback information includes lamp fault information, the lamp control fault may be determined to be a lamp fault; when the feedback information includes communication fault information, the lamp control fault may be determined to be a communication fault.

[0072] Embodiment 3

[0073] Figure 3 This is a flow chart of a lamp control logic principle provided according to Embodiment 3 of the present invention.

[0074] like Figure 3 As shown, the lamp control logic includes:

[0075] The CAN signal of the vehicle is sent periodically. The communication between the MCU and the driver chip inside the lamp adopts the IIC communication protocol, and the communication frequency is adapted according to the MCU resources. In order to ensure that the function is accurately implemented according to the CAN signal instruction, and to prevent the IIC communication from being interfered with by other interference sources, the function can be realized by periodically writing data. For example, if the vehicle instruction is to keep the position light on, the lamp will continue to receive CAN instruction information. The traditional practice is that the MCU only sends a write operation to the driver IC once, and the position light can also be kept on. However, in order to avoid the driver IC being affected by external static electricity and other factors, in order to reliably realize the continuous lighting of the position light, the MCU periodically repeats the writing of the position light lighting data to the driver chip, and the cycle time can be adjusted to between 50-300ms according to the MCU performance. When the vehicle sends a function change instruction, such as the position light changes from on to off, the MCU identifies the CAN signal and finds that the function instruction has changed. At this time, the function data is immediately written to the driver chip, and there is no need to wait for the periodic function instruction to be sent, so that the function can be switched in real time without delay.

[0076] Specifically, the vehicle-side CAN signal sends the function control instruction to the MCU, and the MCU determines whether the current function control instruction has changed compared with the historical function control instruction transmitted last time. If it is judged to be yes, it immediately sends the function signal to the driver chip, and the driver chip controls the controlled light-emitting diode (LED) to immediately execute the current function control instruction; if it is judged to be no, it intermittently sends the execution signal to the driver chip, and the driver chip controls the controlled LED to execute the function control instruction according to the execution signal.

[0077] Figure 4 This is a flow chart of a lamp function monitoring and diagnosis provided according to Embodiment 3 of the present invention.

[0078] like Figure 4 As shown, the lamp function monitoring diagnosis includes:

[0079] Since the internal functions of the lamps involve driving safety, it is necessary to perform fault detection on each function while ensuring the realization of each function. It is necessary to handle the fault or alarm as soon as possible, and perform periodic fault detection throughout the entire working period of the lamp. Fault detection is divided into communication fault detection and LED line fault detection.

[0080] The communication fault detection process is to first determine whether there is a communication fault between the MCU and the driver chip, and whether they can communicate normally. If a communication fault is determined to occur, and in order to avoid false alarms, the fault detection cycle is set to more than 3 times to determine that it is a real fault. If a real fault occurs, two processing actions are performed. One is to immediately reset the communication between the MCU and the driver chip. Under some special working conditions, the communication failure caused by some peripheral interference sources can be reset and restored by itself. The second is to report the fault information and notify the user of the fault information. However, if the cumulative communication reset is still unsuccessful 3 times in a short period of time, the MCU reset is executed, which can solve most communication faults by itself.

[0081] The LED fault detection process is to judge based on the LED working status feedback from the driver chip. If fault feedback occurs more than 3 times in a row, the LED fault information will be fed back to the entire vehicle to remind the user that the lamp is damaged and needs to be replaced.

[0121] Among them, the external reserved interfaces of the vehicle end include KL30, KL15, brake signal, GND, CAN+, and CAN-. KL15 represents the engine ignition signal and the signal for starting the vehicle; KL30 represents the positive pole of the battery, which provides low-voltage power supply for the MCU, usually 11V-15V; the brake signal is in the form of an electrical signal and an air pressure signal, which generates a brake signal to control the increase and decrease of the brake pressure of the electronic control brake system.

[0122] The vehicle-end interface is connected to the reserved external interface of the vehicle port. KL30 is connected to the DCDC voltage regulator module and the MCU power supply module for low-voltage power supply. The voltage regulator module is connected to each signal light to ensure the stable power supply of the signal light. The CAN transceiver module is connected to the MCU to input control data. The MCU can be connected to multiple driver chips, and each driver chip is connected to a lamp with corresponding function.

[0123] The lamp receives the power supply signal and CAN communication signal from the vehicle, and then sends it to the MCU through CAN transceiver. After the MCU processes the signal, it sends the corresponding command to the driver chip, and the driver chip drives the LED light source to light up, turn off, or light up in a running sequence. The lamp is connected to the battery of the vehicle, and the lamp has power input when the vehicle is working or not. At the same time, in order to ensure functional safety, redundant brake light signal lines are added, and the brake light lighting is controlled by dual signals of CAN signal and brake light signal line.

[0124] It should be understood that the various forms of processes shown above can be used to reorder, add or delete steps. For example, the steps described in the present invention can be executed in parallel, sequentially or in different orders, as long as the desired results of the technical solution of the present invention can be achieved, and this document does not limit this.
