[0002] In the field of automatic driving, the vehicle domain control architecture is divided into two different domain controls, namely "automatic driving domain" and "intelligent cockpit domain". The automatic driving domain is also known as Advanced Driver Assistance Systems (ADAS), and the intelligent cockpit domain is also known as Cockpit intelligent cockpit domain. Around View Monitor (AVM) has strong use scenarios in both the ADAS automatic driving domain and the Cockpit intelligent cockpit domain. For example, the main function of AVM accessing the chip in the ADAS automatic driving domain is automatic parking, or higher-order assisted driving parking by the side, etc. The main function of AVM accessing the chip in the intelligent driving domain is reversing image display. The control schemes of the two independent chips are different in these two scenarios.

[0003] In order to reduce power consumption and improve the cruising range, and current new energy vehicles have a sentinel mode function, therefore, it is required that each controller in the sentinel mode maintains the lowest power consumption and is powered off as much as possible.

[0062] In order to make the objects, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only some of the embodiments of the present application but not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work fall within the scope of protection of the present application.

[0063] The term "module" used herein can be a software or hardware object executed on the computing system. Different components, modules, engines and services described herein can be implemented as software objects on the computing system. The apparatuses and methods described herein can be implemented in software, of course, and can also be implemented in hardware, and both are within the scope of the present application.

[0064] In the description of the present application, it should be noted that the terms "center", "upper", "lower", "left", "right", "inner", "outer" and the like indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, and are only for the purpose of facilitating the description of the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as limiting the present application. In addition, the terms "first", "second", "third" are only for the purpose of description and cannot be understood as indicating or implying relative importance.

[0065] In the description of the present application, it should be noted that, unless otherwise explicitly specified and limited, the terms "connected", "connected" should be understood broadly, for example, it can be fixedly connected, or it can be detachably connected, or integrally connected; it can be mechanically connected, or electrically connected or can communicate with each other; it can be directly connected, or indirectly connected through an intermediate medium, it can be the internal communication of two elements or the interaction relationship between two elements. For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0066] The technical scheme provided by the embodiment of the present application is applied to an automotive electronic and electrical architecture, in which a vehicle domain controller is used to manage and control various systems of the vehicle. The vehicle domain control is an electronic control unit (ECU) integrated with multiple functions. Among them, intelligent / automatic driving and intelligent cockpit are designed as two different domain controls, which are associated with each other through multiple different kinds of data buses, such as controller area network bus, media-oriented system transport bus, etc. As shown in FIG. 1A to FIG. 1B It is illustrated that two automatic driving controllers and intelligent cockpit domain controllers are illustrated.

[0067] Scenario 1: as shown in FIG. 1A The schematic diagram of the raw data of the panoramic camera bypassing the serializer to the cockpit domain for processing provided by the embodiment is shown. The AVM panoramic camera is first connected to the automatic driving controller (such as ADAS_SOC), the automatic driving controller receives, after internal processing of the video stream data collected by the AVM panoramic camera, the processed video stream data is transmitted to the cockpit domain controller (such as Cockpit_SOC) through the coaxial cable bundle bypassing the serializer, and the cockpit domain controller is displayed after internal processing, for use in the autonomous driving domain.

[0068] Among them, SOC (System-on-chip) is a highly integrated and functional chip, which integrates microprocessor (CPU), memory (such as RAM, ROM), input / output interface (I / O), various controllers (such as timer, interrupt controller) and other functional modules (such as digital signal processor DSP, image processor GPU, etc.) on one chip.

[0069] In addition, the AVM around view camera includes camera modules arranged in four directions of front, rear, left and right of the vehicle. Each camera module is connected to the autonomous driving controller through a coaxial cable. The AVM (Around View Monitor) is a modern intelligent driving assistance technology for vehicles, which aims to provide all-round visual safety for drivers.

[0070] Scenario 2: As shown in the figure, it is a schematic diagram of the raw data of the panoramic camera provided by the embodiment after being processed by the autonomous driving controller and transmitted to the cockpit domain for processing. After the system is powered on, the panoramic camera is first connected to the autonomous driving controller, and then the camera video stream data is transmitted to the autonomous driving controller. The autonomous driving controller processes the video stream data first, which is used by the autonomous driving domain. At the same time, the autonomous driving controller ADAS_SOC processes the camera video stream data, and then transmits it to the deserializer in the cockpit domain after being serialized by the serializer. After being deserialized by the deserializer, it is transmitted to the cockpit domain controller (Cockpit_SOC) for processing and display. FIG. 1B

[0071] It should be noted that the above-mentioned bypass transmission refers to a technology of directly connecting to a target device by bypassing traditional intermediate devices such as routers and switches. In the embodiment, it refers to that the video stream data collected by the camera is directly transmitted to the serializer 2 through the deserializer “D-PHY” (MIPI Differential PHY, MIPI Alliance differential serial physical layer interface) interface by bypassing the autonomous driving controller.

[0072] For the above-mentioned “Scenario 1” and “Scenario 2”, the autonomous driving controller needs to process the video stream data, but it will produce a large power consumption, especially for the sentinel mode function, which requires each controller in the sentinel mode to maintain the lowest power consumption and be powered off as much as possible. The above two schemes in the current sentinel mode mainly keep the power device ADAS_SOC powered on, resulting in high power consumption and affecting the CLTC (City Driving Long-Trip Cycle) range. The CLTC is a standard for evaluating the range of electric vehicles.

[0073] The embodiment of the present application provides a vehicle environment perception control system for realizing the power-off of the autonomous driving chip or the autonomous driving controller (abbreviated as ADAS_SOC) in the sentinel mode of the vehicle, and keeping the microprocessor in the autonomous driving domain, such as ADAS_MCU, in the power-on state, thereby reducing the power consumption in the sentinel mode and improving the range.

[0074] Embodiment one​

[0075] In this embodiment, a vehicle environment perception control system is provided, which has a structure as shown in the figure. FIG. 2 The vehicle environment perception control system includes a panoramic camera or camera module, an autonomous driving domain, and a cockpit domain.

[0076] The cockpit domain includes a cockpit chip and a first microprocessor (MCU1), and can further include a first deserializer connected to the cockpit chip through an I2C connection and a DPHY protocol connection. DPHY (DisplayPort Physical Layer) is an important component of the DisplayPort standard, mainly responsible for transmitting and receiving physical signals in the DisplayPort interface.

[0077] Optionally, the cockpit domain can also be a Cockpit intelligent cockpit, also known as an intelligent cockpit, which is a car interior environment integrated with multiple advanced technologies and functions, aiming to provide a more comfortable, convenient and safe driving experience. It combines intelligent and networked technologies, software and hardware, and continuously learns and iterates to intelligently perceive and make intelligent decisions in the intelligent cockpit space.

[0078] The autonomous driving domain includes an autonomous driving chip, a second microprocessor (MCU2), at least one serializer and a second deserializer (deserializer 2). Specifically, the number of serializers can be one or more, which can be set according to actual needs. FIG. 2 Two serializers are shown in the figure, which are a first serializer (serializer 1) and a second serializer (serializer 2), and the two serializers are connected to the second deserializer.

[0079] In addition, the autonomous driving domain can further include a POC (Power over Coaxia) power supply chip and a power management chip, which can also be referred to as a POWER chip. The POC power supply chip is connected to the camera module, and the power management chip is connected to the first serializer, the second serializer and the first deserializer.

[0080] The second deserializer is connected with the camera module, is used for decoding the data transmitted by the camera coaxial line into MIPI-CSI protocol data, and then transmitting the data to the automatic driving chip through CPHY, so that the automatic driving chip processes the self-driving related functions; at the same time, the data is transmitted to the first and second serializers through DPHY. The first and second serializers are used to complete the camera video data in the automatic driving chip, convert the parallel transmission into serial transmission, and access the first deserializer in the cabin domain through the coaxial line through the connector.

[0081] The automatic driving chip, such as ADAS SOC, is used to receive camera video data in a normal scene, process the self-driving related algorithm functions, control the first and second serializers, and the power supply of the second deserializer and the camera module, and control the second deserializer and generate an internal synchronization signal to control the camera exposure media stream through I2C, and in a normal driving scene, complete the diagnosis of the camera and the serializer / deserializer.

[0082] The second microprocessor MCU2 is used to control the first and second serializers, and the power supply of the second deserializer and the camera module, control the camera exposure stream through I2C, and complete the diagnosis of the camera and the serializer / deserializer in the sentinel mode.

[0083] It should be noted that in the embodiments of the present application, the specific implementation of the cabin chip and the automatic driving chip can also be a controller, such as a cabin domain controller and an automatic driving controller, or other variants, for example, the self-driving domain controller is changed to an automatic driving L4 level controller, the cabin domain controller is changed to a cabin-driving integrated controller or a cabin-driving integrated controller, and the present application does not limit this.

[0084] Specifically, in the present embodiment, the cabin chip is in a suspended mode, which can be called a sleep mode, or a STR (Suspend to RAM) mode, which is a low-power running state of a computer or other electronic device.

[0085] In the case of locking the car and powering off, the cabin chip is in a suspended mode, and each device in the automatic driving domain is in a powered-off state.

[0086] The MCU1 is used to generate a wake-up instruction when receiving an entering sentinel mode instruction from a terminal device, and send the wake-up instruction to the cabin chip; the wake-up instruction is used to control the cabin chip to switch from the suspended mode to the working mode.

[0087] The MCU1 is also used to send a sentinel mode signal to the MCU2.

[0088] MCU2, configured to receive the sentry mode signal, start power-on operations of the camera module, the serializer (e.g., the first serializer and the second serializer), and the second deserializer, and configure the second deserializer to generate a synchronization signal to be transmitted to the camera module through the reverse channel.

[0089] The camera module is configured to output a media stream to the MCU2 after receiving the synchronization signal.

[0090] The second deserializer is configured to receive the media stream from the camera module and transmit the media stream to the first deserializer in the cabin domain through the serializer.

[0091] At this time, in the sentry mode, the autonomous driving chip is in a power-off state, and the MCU1, the MCU2, and the cabin chip are all in a working mode. Thus, unnecessary energy consumption is avoided when the car is powered off.

[0092] In addition, the MCU2 is specifically configured to generate a first indication signal and a second indication signal when receiving the sentry mode signal, and send the first indication signal to the POC power supply chip and the second indication signal to the power management chip. The POC power supply chip is configured to receive the first indication signal and power on the camera module, and the power management chip is configured to receive the second indication signal and power on the first serializer, the second serializer, and the second deserializer.

[0093] The following will be described in detail FIG. 3 the vehicle environment perception control method provided in this embodiment.

[0094] FIG. 3 is a signaling flowchart of a vehicle environment perception control method according to an embodiment of the present application. The method is applied to the vehicle environment perception control system shown in the foregoing FIG. 2 The method provided in this embodiment can be applied to the case of powering off the car, such as when the driver gets off the car and powers off after driving to the destination. The method provided in this embodiment includes the following steps.

[0095] S101: The whole vehicle is powered off, and the user remotely operates a terminal device App to generate an entering sentry mode instruction and sends the instruction to a communication device through the terminal device.

[0096] The communication device can be a TBOX (Telematics BOX, remote information processor), which is a key component in the Internet of Vehicles system. The TBOX realizes information interaction between the vehicle and the outside world through a built-in communication module (such as 4G, 5G, or Bluetooth, etc.). It can send real-time data of the vehicle, such as speed, fuel consumption, fault codes, etc., to the cloud platform, and also can receive instructions from the cloud platform or the mobile phone APP, such as remote control of the vehicle unlocking, starting the engine, turning on the air conditioner, etc.

[0097] The communication device is connected with the MCU 1 bus. The communication device is used to receive the entering sentinel mode instruction sent by the terminal device, and send the instruction to the MCU 1. The instruction is used to instruct the MCU 1 to start the whole vehicle power-off, and wake up the cabin chip.

[0098] S102: After the communication device receives the instruction, the CAN signal is sent to the MCU 1 through the CAN bus.

[0099] The CAN signal carries the entering sentinel mode instruction. The instruction is used to remotely wake up the cabin chip, because when the whole vehicle is powered off and enters the sentinel mode, the cabin chip is in the STR mode.

[0100] S103: The MCU 1 generates and sends a wake-up instruction to the cabin chip.

[0101] The wake-up instruction is used to wake up the cabin chip. After the cabin chip receives the wake-up instruction, it enters the working mode from the STR mode. At this time, the automatic driving chip is in the power-off state, and the MCU 2 is in the power-on state or enters the working mode, so the MCU 1 sends the wake-up instruction to the MCU 1 of the cabin domain.

[0102] S104: The MCU 1 sends a sentinel mode signal to the MCU 2, which is used to inform the MCU 2 to enter the sentinel mode.

[0103] One embodiment is to inform the MCU 2 by sending an ICAN signal carrying the sentinel mode signal, wherein ICAN (Industrial CAN-BUS Application Protocol) is an industrial CAN-BUS application layer protocol. The ICAN protocol follows the bus network physical layer and data link layer specified in the CAN protocol standard, and redefines the frame identifier and data field in the CAN-BUS message. In this step, the MCU 1 uses the ICAN signal to issue the sentinel mode signal to the MCU 2, realizing the communication between the MCU 1 of the cabin domain and the MCU 2 of the automatic driving domain.

[0104] S105: After the MCU 2 receives the sentinel mode signal, the first indication signal (indication signal 1) and the second indication signal (indication signal 2) are generated, and the first indication signal is sent to the POC power supply chip, and the second indication signal is sent to the power management chip.

[0105] After the POC power supply chip receives the first indication signal, the remote camera module is powered on. On the other hand, after the power management chip receives the second indication signal, the first deserializer, the first serializer and the second serializer are powered on.

[0106] S106: MCU2 configures the register in the second deserializer through I2C, controls the second deserializer to generate an internal synchronization signal, and transmits the internal synchronization signal to the remote camera module through the GMSL2 reverse channel for controlling the remote camera module to expose the outflow.

[0107] GMSL2 (Gigabit Multimedia Serial Link 2) is a high-speed serial communication standard specially designed for the automotive field, mainly used for data transmission between vehicle-mounted cameras, sensors and central processors or display screens.

[0108] The camera module captures the surrounding environment to generate a media stream, which includes video data and / or pictures.

[0109] S107: When the cockpit chip detects that the sentinel mode is entered in step S103, the cockpit chip controls the first deserializer to perform an initialization process through I2C, and at the same time, controls the first and second serializers in the autonomous driving domain to perform initialization through the GMSL coaxial reverse transmission.

[0110] When the first and second serializers are both initialized and the first deserializer also performs initialization, the signals are synchronized at this time, and the second deserializer in the autonomous driving domain receives the media stream captured by the camera module, deserializes the media stream and sends it to the first and second serializers, and the first and second serializers transmit the media stream to the first deserializer in the cockpit domain through GMSL2. The first deserializer deserializes the media stream and displays video or photo information through the car screen.

[0111] At this time, after the above step S107, the sentinel mode of the system is started, and the cockpit chip, MCU1 and MCU2 are in working mode, and the autonomous driving chip is in a power-off state.

[0112] It should be noted that the above steps S104 and S107 can be executed in parallel or sequentially, and the present embodiment does not limit this.

[0113] The method provided by the embodiment of the application sends a sentinel mode signal from the MCU 1 in the cockpit domain to the MCU2 in the autonomous driving domain, so that the MCU2 in the autonomous driving domain can start the power-on operation of the camera module, the serializer and the second deserializer and perform related configuration. In addition, only necessary components such as the camera module, MCU1 and MCU2 can be started to enter the sentinel mode in specific situations (such as when the vehicle is powered off), to monitor the surrounding environment, while the autonomous driving chip is in a power-off state, further reducing system power consumption and prolonging vehicle battery life, reducing cost and energy consumption while meeting monitoring requirements, and prolonging the service life of the autonomous driving chip.

[0114] For example, the actual power consumption of the current automatic driving chip in the sentry mode is about 60W. The method provided in the embodiment can save 0.6KWh of electricity and improve the endurance by 4.2Km in 10 hours of sentry mode per night, and the calculation formula is: 0.6KWh*7Km / KWh=4.2Km.

[0115] In addition, the second deserializer generates a synchronization signal and transmits it to the camera module through the reverse channel. After receiving the synchronization signal, the camera module exposes the media stream to the second deserializer. The synchronization signal ensures the synchronization and accuracy of data acquisition and transmission, ensuring that all parts of the system work together at the right time, avoiding confusion in data transmission and function startup, and improving the stability and reliability of the system.

[0116] According to the test data, the camera module in this scheme can start displaying within 5s, which is at least 10s longer than the original scheme, saving 5s or even less time.

[0117] Embodiment Two

[0118] This embodiment is based on the above FIG. 2 The vehicle environment perception control system structure shown in the figure also provides another vehicle environment perception control method. The difference between this method and Embodiment One is the application scenario. Embodiment One is applied to the situation of locking the vehicle and powering off. This embodiment is applied to the situation of the vehicle being in the park (P) gear.

[0119] In the case of the whole vehicle being in the park gear, the automatic driving chip has control over the camera module, the second deserializer, and the serializer.

[0120] In this embodiment, MCU1 is used to generate a wake-up instruction based on user operation in the case of the whole vehicle being in the park gear, and send the wake-up instruction to the cockpit chip; the wake-up instruction is used to control the cockpit chip to switch from the suspended mode to the working mode.

[0121] The cockpit chip receives the enter-sentry-mode instruction from the car machine large screen and sends the enter-sentry-mode instruction to MCU1.

[0122] MCU1 is used to send a sentry mode signal to MCU2 after receiving the enter-sentry-mode instruction.

[0123] MCU2 is used to communicate with the automatic driving chip when receiving the sentry mode signal, and notify the automatic driving chip to transfer the control right.

[0124] MCU2 is also used to take over the control right of the camera module, as well as the serializer and the second deserializer, to make the second deserializer generate an internal synchronization signal and complete the transfer of control right. The automatic driving chip starts the power-off process after transferring the control right.

[0125] Specifically, one implementation of handing over the control right is that the MCU 2 sends a handover message to the automatic driving chip through a preset channel; after receiving the handover message, the automatic driving chip hands over the control right to the MCU 2.

[0126] In addition, the MCU 2 is also configured to configure the second deserializer to generate a synchronization signal, which is transmitted to the camera module through a reverse channel. The camera module is configured to output a media stream after exposure to the second deserializer after receiving the synchronization signal.

[0127] Meanwhile, the MCU 2 is also configured to control the power supply module to power off the automatic driving chip after detecting that the automatic driving chip completes the power-off process. The second deserializer sends the media stream to the first serializer and the second serializer, and the first serializer and the second serializer serialize the media stream and then transmit the serialized media stream to the first deserializer of the cockpit chip. The first deserializer deserializes the media stream and then displays video or photo information through the car machine large screen.

[0128] The method provided in the embodiment will be described in detail below. FIG. 4 As shown in FIG. 6, it is a signaling flowchart of another control method according to the embodiment of the application. The method comprises the following steps: FIG. 4

[0129] S201: The cockpit chip receives an entering sentinel mode instruction from the car machine large screen.

[0130] When the whole vehicle is in the parking gear, the user enters the sentinel mode by operating the car machine large screen, at this time, the car machine large screen sends the entering sentinel mode instruction to the cockpit chip.

[0131] S202: The cockpit chip sends the entering sentinel mode instruction to the MCU 1.

[0132] S203: After receiving the entering sentinel mode instruction, the MCU 1 sends a sentinel mode signal to the MCU 2.

[0133] Specifically, the MCU 1 sends the entering sentinel mode signal to the MCU 2 through the ICAN signal. The sentinel mode signal is used to inform the MCU 2 to control the second deserializer. At this time, the automatic driving chip (ADAS_SOC) is in the working mode, and the MCU 2 is also in the working mode.

[0134] S204: After receiving the sentinel mode signal sent by the MCU 1, the MCU 2 sends a message through the SPI channel to inform the automatic driving chip to hand over the control right of the camera module and the second deserializer to itself.

[0135] ​Because the automatic driving chip has control over the first deserializer, the first serializer, and the second serializer at this time, the automatic driving chip needs to hand over control to the MCU2 in this step. After the control is handed over to the MCU2, the automatic driving chip returns a state message to the MCU2, notifying the MCU2 that the control has been handed over.

[0136] Optionally, the automatic driving chip is connected to the MCU through a serial interface; the MCU2 can notify the automatic driving chip to hand over control through the serial interface, and receive the control held by the automatic driving chip.

[0137] S205: The automatic driving chip hands over the control to the MCU2 through the serial interface.

[0138] S206: The MCU2 configures the register of the second deserializer through I2C to control the second deserializer to generate an internal synchronization signal, which is transmitted to the remote camera module through the GMSL2 reverse channel, and controls the remote camera to expose the outflow.

[0139] This step is the same as step S106 of the above embodiment, which will not be described here. In addition, the method further comprises:

[0140] S207: The automatic driving chip executes a safe power-down process.

[0141] S208: After the automatic driving chip completes the power-down process, the MCU2 is notified that the power-down process is completed, and the MCU2 controls the power supply module to disconnect the power supply to the automatic driving chip. At this time, the automatic driving chip is in a power-off state, but the MCU2 is in a power-on state.

[0142] The second deserializer controls the camera module to expose the media stream, and then sends the media stream to the first serializer and the second serializer; the first serializer and the second serializer receive the media stream and transmit it to the first deserializer of the cabin domain. The first deserializer deserializes the media stream and displays video or photo information through the car screen.

[0143] At this time, the sentinel mode of the automatic driving domain and the cabin domain is started, and the cabin chip, MCU1 and MCU2 are started in the sentinel mode, and the automatic driving chip is powered off.

[0144] The method provided in this embodiment is in the sentinel mode, and the automatic driving chip is in a power-off state, which effectively reduces the power consumption of the system. When the vehicle is in the sentinel mode, only the necessary hardware components (such as the camera module, the serializer, and the first deserializer) are started to realize the monitoring function, and the automatic driving chip with high power consumption is turned off. While ensuring the normal operation of the sentinel mode, the energy is saved, the battery life of the vehicle is prolonged, and the energy utilization efficiency of the vehicle is improved.
