[0032] It is easy to understand that according to the technical solution of the present application, without changing the essential spirit of the present application, a person skilled in the art can propose a variety of interchangeable structural modes and implementation modes. Therefore, the following specific implementation modes and drawings are only exemplary descriptions of the technical solution of the present application, and should not be regarded as the entirety of the present application or as a limitation or restriction on the technical solution of the present application.

[0033] The directional terms such as up, down, left, right, front, back, front, back, top, bottom, etc. mentioned or may be mentioned in this specification are defined relative to the structures shown in the drawings. They are relative concepts and may change accordingly according to their different positions and different usage states. Therefore, these or other directional terms should not be interpreted as restrictive terms. In addition, the terms "first", "second", "third", etc. or similar expressions are only used for description and distinction purposes, and cannot be understood as indicating or implying the relative importance of the corresponding components or the order or assembly order of the components.

[0034] refer to Figure 1 , which shows a module schematic diagram of a vehicle drive system 100 proposed according to an embodiment of the present application. The vehicle drive system 100 includes an electric drive module 101, an acquisition module 102, a communication module 103 and a display module 104. The electric drive module 100 includes a motor, a motor controller and a transmission mechanism, and the transmission mechanism is configured as a gear box, for example. The motor outputs power through the transmission mechanism, and its speed and output torque are controlled by the motor controller. In one embodiment of the present application, the electric drive module 101 may also include one or more of the subsystems such as a distribution box (PDU, Power Distribution Unit, or power distribution unit), a charger (OBC, On-board charger, or vehicle charger) and a DC-to-DC converter (DCDC, DC-to-DC converter). The electric drive module 101 converts the high-voltage electric energy input to the motor into mechanical energy for vehicle travel, and can recover the mechanical energy during vehicle braking and convert it into high-voltage electric energy. Through the above-mentioned DC-DC converter, the electric drive module 101 can also convert DC high-voltage electric energy into DC low-voltage electric energy or DC high-voltage electric energy of a higher voltage level. For the electric drive module, it carries alternating mechanical loads or electrical loads during vehicle use, which may cause fatigue failure of components after a long period of accumulation. Key components in the electric drive module 101 that are prone to fatigue failure include, for example, bearings, gears, busbar capacitors, power modules (IGBT / SiC), high-voltage connectors, copper busbars, etc. Real-time monitoring of these components is the key to determining the working status and fatigue aging status of the electric drive module.

[0035] The acquisition module 102 includes sensors for detecting components, especially the operating status of key components in the electric drive module 101 that are prone to fatigue failure. The acquisition module 102 sends the sensor signal to the communication module 103. Since the load forms borne by the key components in the electric drive module 101 are different during operation, the failure forms after bearing the load are also different. For example, after the bearing becomes abnormal or fails due to bearing mechanical load, there will be abnormal vibration or abnormal sound, and after the power module becomes abnormal or fails due to bearing electrical load, there will be abnormal current or temperature rise. Therefore, in one embodiment of the present application, multiple sensors are required to determine the operating status of each key component, and these sensors include one or more of acceleration sensors, temperature sensors, current sensors, voltage sensors, humidity sensors, air pressure sensors, flow sensors, and position sensors. The sensor sends the measured data to the communication module 103 in the form of a signal after parsing, for example, through ADC (Analog-to-Digital Converter), SPI (Serial Peripheral Interface), I2C (Inter-Integrated Circuit), PWM (Pulse Width Modulation), DSADC (Sigma-Delta ADC), etc., to the processor's register. The processor then moves the data in the register to RAM (Random Access Memory) for cache or directly sends it to LIN (Local Interconnect Network), CAN (Controller Area Network), CAN FD (CAN with Flexible Data rate) or Ethernet as needed.

[0036] The communication module 103 interacts with the acquisition module 102 and the cloud, processes the sensor signal, sends the obtained data to the cloud, receives the warning signal sent from the cloud, and sends the warning signal to the display module 104, wherein the warning signal is used to characterize the working state and / or life cycle information of the electric drive module 101 and / or its components. The communication module 103 is, for example, a vehicle-mounted terminal or is arranged in a vehicle-mounted terminal, and the processed data can be synchronized to the cloud or edge device end through the communication module 103, or the data corresponding to the sensor signal can be synchronized to the cloud or edge device end by the acquisition module 102 itself. The communication module 103 plays the role of routing between the electric drive module 101 and the cloud, and it can realize data transmission with the cloud through 4G / 5G communication and other forms.

[0037] In one embodiment of the present application, the communication module 103 also includes an edge computing device, which communicates and interacts with the acquisition module 102, processes the sensor signal from the acquisition module 102, and sends the processed data to the cloud. If an edge computing device, such as a GPU (Graphics Processing Unit, graphics processor) core, is provided in the communication module 103, the data in the RAM can also be moved to the edge computing device for data processing and calculation. In other words, the processing and calculation of the data measured by the sensor can be uploaded to the cloud through the communication module 103 and performed in the cloud, or edge computing can be performed inside the drive system or other subsystems on the vehicle side, and can also be calculated on the cloud and edge device side at the same time. The edge computing device can provide a part of the computing power for the data processing of the data measured by the sensor. The sensor signal of the acquisition module 102 can be sent to the communication module 103 in the form of LIN, CAN, CANFD, Ethernet, etc., and then the communication module 103 synchronizes the data to the cloud or edge device side.

[0038] In one embodiment of the present application, the warning signal includes one or more of an overall estimated life signal of the electric drive module, an estimated life signal of a component of the electric drive module, and an abnormal component diagnosis and warning signal.

[0039] The display module 104 receives the warning signal from the communication module 103 and displays it to the user. The display module 104 is mainly used to display the warning signal, and it can realize data transmission with the communication module 103 in the form of LIN, CAN, CANFD, Ethernet, etc. The display module 104 includes, for example, various vehicle-mounted instruments.

[0040] In one embodiment of the present application, the communication module 103 also communicates and interacts with the vehicle system. The communication module 103 receives update data sent from the cloud and sends it to the vehicle system. The update data is used to represent configuration parameters that meet the current driving conditions.

[0041] In one embodiment of the present application, the communication module 103 further includes a data marking module, in which working condition data is preset, and the data marking module marks the corresponding data according to the working condition data. After the data marking module marks the corresponding data, it uploads it to the cloud, so that more accurate data under specific working conditions can be obtained, which is conducive to the subsequent fault diagnosis work.

[0042] In one embodiment of the present application, the communication module 103 also includes a data freezing module. At the moment of a fault, especially an unknown fault or a sudden fault, the data freezing module stores data corresponding to relevant signals at the moment of the fault and in the previous time period for subsequent fault analysis and diagnosis, thereby optimizing the artificial intelligence model and improving the safety of the vehicle.

[0043] It should be understood that the communication method or data transmission method between the modules mentioned above is not restrictive, and those skilled in the art can select a suitable communication method or data transmission method according to actual needs.

[0044] Another aspect of the present application also provides a vehicle-cloud interaction system 1000. Figure 2 , which shows a module schematic diagram of a vehicle-cloud interaction system proposed according to an embodiment of the present application. The vehicle-cloud interaction system 1000 includes the vehicle drive system 100 described above, and also includes a cloud 200, which includes

[0045] The diagnosis and warning module 201 receives and processes the data sent by the communication module 103 , obtains a warning signal and sends it to the communication module 103 .

[0046] The sensor signal collected by the acquisition module 102 is first converted into data, and then the data is uploaded to the cloud for data processing. The data processing methods include but are not limited to deleting duplicate values, missing value processing, outlier processing, data dimension reduction, feature derivation, data noise filtering, etc. The diagnosis and warning module 201, for example, uses artificial intelligence methods to obtain warning signals based on data. The cloud will construct an artificial intelligence model for the processed data, and the diagnosis and warning module 201 can be used to implement the construction operation of this artificial intelligence model. The diagnosis and warning mainly realizes the functions of abnormal monitoring, diagnosis and warning, life estimation, etc. of the vehicle drive system 100.

[0047] In one embodiment of the present application, the cloud also includes a calibration module, which obtains an expert model and user demand information from the cloud. The calibration module processes the data received from the cloud according to the expert model and user demand information to obtain updated data, and sends the updated data to the communication module. The updated data can be used to remotely optimize the vehicle configuration and parameters, and implement functional iteration, so that the vehicle system is more adapted to the current driving conditions and more in line with the user's driving behavior habits, providing users with a safer, more efficient, and smarter driving experience. The calibration process of the calibration module can also be carried out through an expert model or artificial intelligence.

[0048] Another aspect of the present application provides a vehicle, which includes the vehicle drive system 100 described above.

[0049] It should be understood that the vehicle drive system of the present application can be installed on various vehicles, including cars, trucks, buses, hybrid vehicles, pure electric vehicles, etc. Therefore, the subject matter of the present application is also intended to protect various vehicles equipped with the vehicle drive system of the present application.
