[0027] To more clearly illustrate the technical solutions of the embodiments of this application, the following is a brief introduction to the drawings required for describing the embodiments. Obviously, the drawings described below are merely examples or embodiments of this application. Those skilled in the art can apply this application to other similar scenarios based on these drawings without inventive effort. Unless otherwise apparent from the context or otherwise noted, the same reference numerals in the figures represent the same structure or operation.

[0028] As used in this application and the claims, unless the context clearly indicates otherwise, the words "a," "an," "an," and / or "the" are not intended to refer to the singular but may include the plural. Generally speaking, the terms "comprises" and "include" only indicate the inclusion of the steps and elements specifically identified, and these steps and elements do not constitute an exclusive list. A method or apparatus may also include other steps or elements.

[0029] Unless otherwise specifically stated, the relative arrangement of the components and steps, the numerical expressions and the numerical values set forth in these embodiments do not limit the scope of this application. Meanwhile, it should be understood that for ease of description, the sizes of the various parts shown in the drawings are not drawn according to the actual proportional relationship.

[0030] Furthermore, it should be noted that the use of terms such as "first" and "second" to define components is solely for the purpose of distinguishing the corresponding components. Unless otherwise stated, these terms have no special meaning and therefore should not be construed as limiting the scope of protection of this application. Furthermore, while the terms used in this application are selected from commonly known and commonly used terms, some terms mentioned in this specification may have been selected by the applicant at his or her discretion, and their detailed meanings are explained in the relevant sections of this description. Furthermore, this application should be understood not only by the actual terms used, but also by the meaning implied by each term.

[0031] It should be understood that when a component is referred to as being “on another component,” “connected to another component,” “coupled to another component,” or “contacting another component,” it can be directly on, connected to, coupled to, or contacting the other component, or intervening components may be present. In contrast, when a component is referred to as being “directly on another component,” “directly connected to,” “directly coupled to,” or “directly contacting” another component, there are no intervening components. Similarly, when a first component is referred to as being “electrically in contact with” or “electrically coupled to” a second component, an electrical path exists between the first and second components that allows current to flow. This electrical path may include capacitors, coupled inductors, and / or other components that allow current to flow, even without direct contact between the conductive components.

[0032] The embodiments of the present application describe a vehicle intelligent driving domain control system.

[0033] Figure 1 This is a schematic diagram of the composition of a vehicle intelligent driving domain control system according to an embodiment of the present application.

The SoC may also be referred to as a system on a chip (SoC). The control system communication module is configured to transmit status indication signals 121a and / or 121b to the controller.

The status indication signal 121b of the Ethernet communication module 123 is transmitted via a system-on-chip processor (e.g., Figure 1 The second power supply signal 153b is transmitted to the controller 102 via the processor 112 of the system-on-chip 132 in the control system 102. The second power supply signal 153b is converted into a voltage signal 125a by the second voltage conversion device 125 to power the control system communication module 121.

Each battery has a corresponding status monitoring module; the battery status detection module is configured to send a status abnormality signal 155a or 156b to the controller 102 when the power supply status of the battery 155 or 156 is abnormal. The first power input circuit 152 and the second power input circuit 153 respectively include a temperature monitoring module; the temperature monitoring module is configured to send an overtemperature warning signal 152c or 153d to the controller 102 when it is detected that the temperature of the first power input circuit and the second power input circuit exceeds a threshold.

[0040] Figure 5 1 is a schematic diagram of the third monitoring signal flow and the fourth monitoring signal flow between the controller and the processor according to an embodiment of the present application. Figure 5 , the third monitoring signal flow includes: SPI communication status monitoring signal, GPIO communication status monitoring and / or Ethernet communication status monitoring signal. For example, the third monitoring signal flow 111a between the controller 102 and the processor 111 includes: SPI communication status monitoring signal 111a1, GPIO communication status monitoring 111a2 and Ethernet communication status monitoring signal 111a3. The third monitoring signal flow 112a between the controller 102 and the processor 112 includes: SPI communication status monitoring signal 112a1 and GPIO communication status monitoring 112a2.

[0041] Figure 6 This is a schematic diagram of the composition of a vehicle intelligent driving domain control system according to another embodiment of the present application. Figure 6The vehicle intelligent driving domain control system 100 also includes a sensor module 192 and a corresponding sensor control module 191. The second power input circuit 153 outputs a second power supply signal 153b to power the sensor control module 192 and the sensor module 191; the sensor control module 191 provides a sensor device status monitoring signal 191a and transmits it to a system-level chip processor (for example, the processor 111 of the system-level chip 131). The sensor module 192 includes, for example, a camera device and / or a radar device. The vehicle intelligent driving domain control system 100 also includes a first voltage conversion device 193. The second power supply signal 153b is passed through the first voltage conversion device 193 to power the sensor control module 191 and the sensor module 192.

[0043] The vehicle intelligent driving domain control system of the present application directly shuts down the system communication module (for example, including the Ethernet module and the CAN module) through the main power management module of the main controller module when the power supply voltage is abnormal, preventing the controller from sending messages to the outside when it is uncontrolled, avoiding misoperation of the intelligent driving domain function, and improving the safety of vehicle operation.

[0044] The technical solution of this application, through a dual-power supply method, achieves independent power supply for the microcontroller module and the system-on-chip, improving the functional safety level of the system, while also monitoring various faults of the power input module, including undervoltage, overvoltage, overcurrent, overheating, etc. Furthermore, the two or more input power sources can independently monitor their own undervoltage, overvoltage, overcurrent, and overtemperature faults and can shut down in a timely manner, thereby realizing the function of protecting the power supply. The two or more power sources not only operate independently, but also quickly switch to the other power supply when one of them shuts down due to a fault, thereby ensuring the normal operation of the back-end power supply, truly realizing power isolation between different areas within the domain controller.

[0045] The technical solution of this application not only implements multiple state monitoring between the power management module and the controller, and between the power management module and the processor, but also implements multiple monitoring methods between the controller and the processor, and between processors, achieving comprehensive system status monitoring. The technical solution of this application also has flexible scalability, and the number of system-level chips can be increased as needed within the basic topology to improve the operational performance of intelligent driving.
