[0043] When the vehicle encounters an emergency (such as a collision, etc.), it is necessary to save important vehicle status data and key audio and video data to a non-volatile memory, and this process is called vehicle data disk-off. The vehicle data disk-off function is of great significance for accident investigation, fault troubleshooting, driving behavior monitoring, and vehicle performance optimization. In the existing electronic and electrical architecture of vehicles, the vehicle status data disk-off function is achieved through a telematics box (T-BOX), and the audio and video data disk-off function is achieved through a driving recorder. However, with the continuous development of the automotive industry towards intelligence, in the new EEA, the functions of the T-BOX and the driving recorder no longer exist independently, but the vehicle head unit will undertake the above data disk-off function. How the vehicle head unit realizes vehicle data disk-off in an emergency has become an urgent problem for those skilled in the art.

[0044] To solve the problems of the existing technology, the embodiments of the present application provide a vehicle data disk-off system, method, device, and vehicle. First, the vehicle data disk-off system provided by the embodiments of the present application will be introduced below.

As Figure 1 Shown, a vehicle data disk-off system 100 may include: a power supply unit 120, a microcontroller unit 1101, an Ethernet switch controller 1102, a wireless communication unit 1103, and a system-on-chip 1104.

[0046] The power supply unit 120 is used to receive an external power input and supply power.

[0047] The Ethernet switch controller 1102 is connected to the power supply unit and is used to obtain vehicle status data and first audio-video data transmitted by an external domain controller;

The target trigger signal includes at least one of an attitude anomaly trigger signal, a hard wire trigger signal, and a bus trigger signal.

[0051] In the vehicle data disk-down system according to the embodiment of the present application, the power supply unit can be used to receive an external power input and supply power. The Ethernet switch controller is used to obtain vehicle status data and first audio-video data transmitted by an external domain controller. The system-on-chip is used to receive the first audio-video data transmitted by the Ethernet switch controller and obtain second audio-video data collected by the vehicle. The wireless communication unit is used to receive the vehicle status data transmitted by the Ethernet switch controller. The micro-control unit is connected to the Ethernet switch controller, the system-on-chip, the wireless communication unit, and the power supply unit, and is used to, in response to a target trigger signal and when the external power input is normal, control the wireless communication unit to transmit the vehicle status data to the cloud server, and control the system-on-chip to store the first audio-video data and / or the second audio-video data in an external memory. The target trigger signal includes at least one of an attitude anomaly trigger signal, a hard wire trigger signal, and a bus trigger signal. Thus, in the embodiment of the present application, when an abnormal situation occurs in the vehicle, without a T-BOX and a driving recorder, the micro-control unit can control the wireless communication unit to transmit the vehicle status data to the cloud server, and control the system-on-chip to store the first audio-video data and / or the second audio-video data in an external memory, thereby realizing vehicle data disk-down.

[0056] The above-mentioned wireless communication unit 1103 is responsible for wireless communication and cellular network functions, and realizes functions such as making calls, data downloading, vehicle-cloud communication, etc. Exemplarily, the wireless communication unit can be a 5G communication unit, which is not limited to this in this application, and can also be other units with wireless communication functions.

[0057] The above-mentioned micro-control unit 1101 can realize the real-time processing function of the vehicle-mounted system. The micro-control unit 1101, as a real-time controller, controls other subsystems and devices.

[0058] The above-mentioned external memory can be an external non-volatile memory (USB flash drive, TF card, SD card, etc.) for recording audio and video data during driving.

[0059] Figure 2 The communication architecture of the vehicle data disk system provided by the embodiment of the present application is shown, which can ensure the complete transmission and storage of vehicle status data and audio and video data.

[0060] As Figure 2 shown, in some embodiments, the above-mentioned system 100 may further include:

[0061] A first memory 1106, the first memory is connected to the system-on-a-chip and the power supply unit;

[0062] The micro-control unit 1101 is further configured to control the system-on-a-chip to store the first audio and video data and / or the second audio and video data in the first memory when a failure of the external memory 1111 is detected.

[0063] The above-mentioned first memory 1106 is an internal non-volatile memory of the system-on-a-chip, and is used to store the first audio and video data and / or the second audio and video data that still need to be saved after power-off.

[0064] In this embodiment, when a failure of the external memory is detected, the system-on-chip stores the first audio-video data and / or the second audio-video data in the first memory, further ensuring that the audio-video data of the vehicle is stored on the disk.

[0065] In some embodiments, the above system 100 may further include:

[0066] A second memory 1105, which is connected to the wireless communication unit and the power supply unit;

[0067] The micro-control unit 1101 is further configured to control the wireless communication unit to store the vehicle status data in the second memory when an abnormality of the wireless communication unit is detected.

[0068] The above second memory 1105 is an internal non-volatile memory of the wireless communication unit and is used to store the vehicle status data that still needs to be saved after a power failure.

[0069] In this embodiment, when an abnormality of the wireless communication unit is detected, the wireless communication unit is controlled to store the vehicle status data in the second memory, further ensuring that the vehicle status data is stored on the disk.

[0070] In some embodiments, the above system 100 may further include:

[0071] An attitude sensor 1107, which is connected to the micro-control unit and the power supply unit, and is configured to collect an attitude abnormality trigger signal and transmit it to the micro-control unit.

[0072] The above attitude sensor continuously senses the attitude of the vehicle when the vehicle is stationary, including the accelerations g1, g2, g3 in three directions and the angles a1, a2, a3 in three directions, and realizes functions such as collision detection or rollover detection.

[0073] In this embodiment, the attitude abnormality trigger signal is collected in time through the attitude sensor connected to the micro-control unit, and the vehicle data is stored on the disk.

[0074] The above Figure 2 may further include an external data pin 1108, a hard wire pin 1109, a CAN communication pin 1110, an external audio-video input pin 1112, and an internal audio-video output pin 1113.

[0075] The external data pin 1108 is used to transmit an external high-speed data stream that conforms to the Ethernet protocol, that is, the vehicle status data and the first audio-video data transmitted by the above external domain controller.

[0076] The hard wire pin 1109 can receive an external trigger signal, specifically, it can refer to a hard wire signal from the airbag. When the airbag is triggered, this signal is valid, indicating that the vehicle has collided.

[0077] The CAN communication pin 1110 can receive highly reliable communication data. Using the CAN / CAN-FD protocol, when the CAN data from other controllers indicates that a certain vehicle state is abnormal in other controllers, including some serious abnormal states of the vehicle such as high-voltage battery pack abnormalities (temperature, voltage, etc.) and electric drive abnormalities, it will notify 1 through CAN.

[0078] The external audio-video input pin 1112 can receive externally input audio-video data, including driving record audio-video data, etc.

[0079] The internal audio-video output pin 1113 can output internally output audio-video data for display on a monitor and audio playback.

[0080] When the microcontroller unit 1101 receives different trigger signals from 1107, 1109, and 1110, it can control 1102, 1103, and 1104 to enter different states.

[0081] Figure 3 The architecture of the power supply unit of the vehicle data disk-down system provided by the embodiment of the present application is shown, which can ensure that the vehicle data disk-down system still works normally when the vehicle power supply is normal and in case of power failure.

[0082] In some embodiments, the above-mentioned power supply unit 120 may specifically include:

[0083] A backup battery 1202, which is used for power supply in case of abnormal external power input;

[0084] A dual-power switching sub-unit 1203, which is connected to the backup battery and is used to switch to the backup battery for power supply in case of abnormal external power input;

[0085] The microcontroller unit 1101 is further configured to control the wireless communication unit and the second memory to transmit vehicle state data to the system-on-chip when detecting abnormal external power input; and control the system-on-chip to store the vehicle state data in the first memory.

[0086] The above-mentioned situation of abnormal external power input may exemplarily be the situation of KL30 abnormality. Usually, serious faults occur when KL30 is abnormal, and the power supply of the external memory is also provided by KL30. By default, the external memory is also abnormal when KL30 is abnormal.

[0087] The above dual - power - switching subunit 1203 can disconnect the backup battery 1202 from the vehicle data disk - down system when KL30 is normal, reducing the leakage current; when KL30 drops abnormally, it connects the backup battery to the vehicle data disk - down system. When KL30 is abnormal, the hardware control automatically connects the backup battery to the system without software participation.

[0088] In this embodiment, when an abnormal external power input is detected, the wireless communication unit and the second memory are controlled to transmit the vehicle status data to the system - level chip, and the system - level chip is controlled to store the vehicle status data in the first memory, so as to ensure data disk - down when the vehicle loses power.

[0089] As an implementation manner of the present application, in order to ensure that the power supply unit can supply power stably, the above - mentioned power supply unit 120 may further include:

[0091] Or a logic - power subunit 1205, the first input end of the or - logic - power subunit is connected to an external power supply, the second input end of the or - logic - power subunit is connected to the output end of the boost - power - supply subunit to access the first voltage, and it is used to output a target voltage for power supply, and the target voltage is the higher voltage of the output voltage of the external power supply and the first voltage.

[0092] The above - mentioned boost - power - supply subunit 1204 can boost the backup - battery voltage to Vboost (i.e., the above - mentioned first voltage);

[0093] The above - mentioned or - logic - power subunit 1205 can be used to select and connect KL30 and Vboost; when KL30 > Vboost, KL30 is connected; when KL30 < Vboost, Vboost is connected. The circuit of this or - logic - power subunit is composed of two diodes or ideal diodes, as Figure 4 shown.

[0094] The output end of the above - mentioned or - logic - power subunit 1205 is the first output pin 1207, which can supply power to all devices in Figure 2 and can include a micro - control unit, a system - level chip, a wireless communication unit, an Ethernet switch controller, a first memory, a second memory, etc.

[0095] In this embodiment, the boost - power - supply subunit boosts the output voltage of the backup battery to a preset first voltage, compares it with the external power supply, and outputs the higher voltage of the output voltage of the external power supply and the first voltage for power supply to ensure that the power supply unit can supply power stably.

[0096] As another implementation of the present application, in order to meet the power supply requirements of different devices, the above-mentioned power supply unit 120 may further include:

[0097] A buck power supply sub-unit 1206, the input end of the buck power supply sub-unit is connected to an external power supply, the output end of the buck power supply sub-unit is connected to the input end of the dual power supply switching sub-unit, and is used to step down the external power supply to a preset second voltage.

[0098] The above-mentioned buck power supply sub-unit 1206 can step down KL30 to Vstep (i.e., the second voltage), and the Vstep voltage is usually 5.0V.

[0099] The output end of the above-mentioned buck power supply sub-unit 1206 is the second output pin 1208, which is a power supply rail of the vehicle and can meet the power supply requirements of other devices.

[0100] The second voltage can also be supplied to the dual power supply switching sub-unit 1203, aiming to maintain the operating state of the boost power supply sub-unit 1204 and eliminate the start-up delay of the boost power supply sub-unit 1204.

[0101] In this embodiment, by stepping down the external power supply to a preset second voltage through the buck power supply sub-unit 1206, the power supply requirements of different devices can be met.

[0102] The above Figure 3 may further include a charging chip 1201 and a third output pin 1209.

[0103] The above-mentioned charging chip 1201 is connected to the external power supply 1210 and the backup battery 1202, and can be used to supply power to the backup battery 1202.

[0104] The above-mentioned third output pin 120, which is an extension of the above-mentioned external power supply 1210, is used to supply power to the devices before the vehicle data disk-down system.

[0105] Figure 5 The flowchart of the vehicle data disk-down method provided by an embodiment of the present application is shown. Optionally, the method of the embodiment of the present application can be applied to the vehicle data disk-down system shown above Figure 1 and specifically includes the following steps:

[0106] S501. Obtain vehicle status data and audio-video data. The audio-video data includes first audio-video data and second audio-video data. The first audio-video data is the audio-video data transmitted by an external domain controller, and the second audio-video data is the audio-video data collected by the vehicle;

[0107] S502. Receive a target trigger signal, where the target trigger signal includes at least one of an attitude anomaly trigger signal, a hard wire trigger signal, and a bus trigger signal;

[0108] S503. In response to a target trigger signal, obtain first status information of an external power supply, where the first status information is used to indicate whether there is an abnormality in the external power supply input.

[0109] S504. When the first status information indicates that the external power supply input is normal, control the wireless communication unit to transmit vehicle status data to the cloud server, and control the system - level chip to store audio - video data in an external memory.

[0110] In the vehicle data disk - down method of the embodiments of the present application, a power supply unit is used to receive an external power supply input and supply power. An Ethernet switch controller is used to obtain vehicle status data and first audio - video data transmitted by an external domain controller. A system - level chip is used to receive the first audio - video data transmitted by the Ethernet switch controller and obtain second audio - video data collected by the vehicle. A wireless communication unit is used to receive vehicle status data transmitted by the Ethernet switch controller. A micro - control unit is connected to the Ethernet switch controller, the system - level chip, the wireless communication unit, and the power supply unit, and is used to, in response to a target trigger signal and when the external power supply input is normal, control the wireless communication unit to transmit vehicle status data to the cloud server, and control the system - level chip to store the first audio - video data and / or the second audio - video data in an external memory. The target trigger signal includes at least one of an attitude abnormality trigger signal, a hard - wire trigger signal, and a bus trigger signal. Thus, in the embodiments of the present application, when an abnormal situation occurs in the vehicle, without a T - BOX and a driving recorder, the micro - control unit can control the wireless communication unit to transmit vehicle status data to the cloud server, and control the system - level chip to store the first audio - video data and / or the second audio - video data in an external memory, thereby realizing vehicle data disk - down.

[0111] In some embodiments, the above - mentioned S504 may specifically include:

[0112] When the first status information indicates that the external power supply input is normal, obtain second status information of the wireless communication unit, where the second status information is used to indicate whether the wireless communication unit is abnormal.

[0113] When the second status information indicates that the wireless communication unit is normal, control the wireless communication unit to transmit vehicle status data to the cloud server, and control the system - level chip to store audio - video data in an external memory.

[0114] In some embodiments, the above - mentioned method may further include:

[0115] When the second status information indicates that the wireless communication unit is abnormal, control the wireless communication unit to store vehicle status data in a second memory, and control the system - level chip to store audio - video data in an external memory.

[0116] In some embodiments, the above method may further include:

[0117] When the first state information indicates an abnormal external power input, in response to a target trigger signal, control the wireless communication unit and the second memory to transmit vehicle state data to the system-on-chip;

[0118] Control the system-on-chip to store the vehicle state data and audio-video data in the first memory.

[0119] To facilitate the understanding of the vehicle data disk-down method in the embodiments of the present application, the actual application process of this vehicle data disk-down method is described as follows:

[0120] After the vehicle runs, the entire system is powered by KL30, and the charging chip charges the backup battery; the Ethernet switch controller routes the vehicle state data transmitted from the external domain controller to 5G (i.e., the above-mentioned wireless communication unit), and 5G uploads this data to the cloud server. If 5G is abnormal, the data is stored in the non-volatile memory corresponding to 5G and uploaded to the cloud again after 5G returns to normal. The audio-video data recorded during driving (including the above-mentioned first audio-video data and second audio-video data) is transmitted to the SOC (i.e., the above-mentioned system-on-chip), and the SOC stores this data in the external non-volatile memory for the user to view at any time.

[0121] The operation process of the vehicle data disk-down system is as Figure 6 shown:

[0122] When an abnormal signal (i.e., the above-mentioned target trigger signal) is given to the micro-control unit MCU, the MCU detects the KL30 voltage state. The abnormal signals include attitude abnormality trigger, hard-wire trigger, and CAN trigger. The definitions of each abnormal signal are shown in Table 1;

[0123] If the MCU detects that the KL30 voltage is abnormal, it executes abnormal handling 1;

[0124] If the KL30 voltage is normal, it judges the 5G state. If 5G is abnormal, it executes abnormal handling 2;

[0125] If 5G is normal, it executes abnormal handling 3.

[0126] The definitions of the above-mentioned various abnormal handling are shown in Table 2.
