The following embodiments are only used to more clearly illustrate the technical solution of the present invention, and cannot be used to limit the protection scope of this application.

[0043] like Figure 1As shown, the Ethernet sleep / wake-up system for a vehicle-mounted high-performance computing platform described in the present invention includes a vehicle-mounted central computing platform, a diagnostic instrument and multiple regional controllers. The computing core, the security core and the vehicle-mounted Switch are deployed on the vehicle-mounted central computing platform. By deploying the Ethernet sleep / wake-up system for the vehicle-mounted high-performance computing platform, the collaborative sleep / wake-up between the vehicle-mounted controllers is realized.

[0044] Specifically, the vehicle-mounted central computing platform deploys a computing core and a security core. There is an inter-core communication mechanism between the computing core and the security core. Information interaction between the computing core and the security core is achieved through inter-core communication, such as sleep / wake-up requests, request sources, Phy ID and other information, and it has heterogeneous core inter-core communication capabilities.

[0045] Specifically, the vehicle-mounted central computing platform deploys an on-board Switch, including multiple Phys, which are respectively connected to the Phys of the computing core, regional controller and diagnostic instrument, to achieve Ethernet connection and Ethernet sleep / wake-up coordination between the vehicle-mounted central computing platform and other nodes, and have vehicle-mounted full-domain Ethernet communication and sleep / wake-up capabilities.

[0046] Specifically, an activation line and a control bus are deployed between the security core of the vehicle central computing platform and the vehicle switch. The activation line is used to implement the notification of the vehicle switch to the sleep / wake-up request of the security core. When the Phy of the vehicle switch is awakened, the activation line is set to valid. When all Phys of the vehicle switch are dormant, the activation line is set to invalid. The control bus is used to implement the external control of the vehicle switch by the security core, and has the ability to sleep / wake up and externally control the vehicle switch.

[0047] Specifically, an activation line is deployed between the security core of the vehicle-mounted central computing platform and the diagnostic instrument to realize the notification of the diagnostic instrument's sleep / wake-up request to the security core. When the diagnostic instrument has a diagnostic request, the activation line is set to valid. When the diagnostic instrument completes the diagnostic service, the activation line is set to invalid, and the diagnostic instrument has the ability to sleep / wake up.

[0048] Specifically, the on-board Switch of the on-board central computing platform and the regional controller are connected through Phy, and the Phy of the on-board Switch is put to sleep / wake up through the Phy of the regional controller, thereby triggering the activation line to notify the on-board central computing platform, realizing Ethernet communication and sleep / wake up between the regional controller and the on-board central computing platform, and having the ability of Ethernet communication and sleep / wake up between the regional controller and the on-board central computing platform.

[0049] In this embodiment, regional controller 1 and regional controller 2 are set. At this time, the vehicle-mounted Switch on the vehicle-mounted central computing platform, including Phy1 / 2 / 3 / 4, is respectively connected to the computing core, regional controller 1, regional controller 2 and Phy of the diagnostic instrument.

[0050] For example, the regional controller 1 and the on-board Switch of the on-board central computing platform are connected via Phy, and the Phy of the on-board Switch is put to sleep / wake up via the Phy of the regional controller 1, thereby triggering the activation line to notify the on-board central computing platform, thereby realizing Ethernet communication and sleep / wake up between the on-board regional controller 1 and the on-board central computing platform, and having the ability of Ethernet communication and sleep / wake up between the regional controller 1 and the on-board central computing platform.

[0051] For example, the regional controller 2 and the on-board Switch of the on-board central computing platform are connected via Phy, and the Phy of the on-board Switch is put to sleep / wake up via the Phy of the regional controller 2, thereby triggering the activation line to notify the on-board central computing platform, thereby realizing Ethernet communication and sleep / wake up between the on-board regional controller 2 and the on-board central computing platform, and having the ability of Ethernet communication and sleep / wake up between the regional controller 2 and the on-board central computing platform.

[0052] like Figure 2 As shown, a vehicle-mounted high-performance computing platform Ethernet sleep / wake-up method, in which the global sleep / wake-up is triggered by a diagnostic instrument, specifically includes the following steps:

[0054] Specifically, the diagnostic instrument initiates a wake-up request to the vehicle-mounted central computing platform through the activation line and has the ability to wake up remotely.

[0055] In the second step, the security core deployed on the vehicle central computing platform receives the wake-up request from the diagnostic instrument activation line, supplies power through the power management module, and wakes up all Phys of the vehicle Switch through the control bus between the vehicle Switch; in this embodiment, it includes Phy1 / 2 / 3 / 4 of the vehicle Switch;

[0056] Specifically, the security core of the vehicle-mounted central computing platform and the vehicle-mounted Switch control the Phy wake-up of the vehicle-mounted Switch through the control bus, and have the ability to externally control Phy sleep / wake-up of the vehicle-mounted Switch.

[0057] In the third step, the security core deployed on the vehicle central computing platform receives the wake-up request from the diagnostic instrument activation line, supplies power through the power management module, and notifies the computing core to wake up Phy through inter-core communication with the computing core. At this time, the vehicle is fully awakened and can provide global diagnostic services, realizing vehicle-wide wake-up coordination.

[0058] Specifically, the computing core and security core of the vehicle-mounted central computing platform realize sleep / wake-up request interaction between heterogeneous cores through inter-core communication, and have the ability to sleep / wake up heterogeneous cores of the vehicle-mounted central computing platform.

[0060] In the fifth step, the security core deployed on the vehicle central computing platform receives the sleep request from the diagnostic instrument activation line and initiates a sleep request to the computing core through inter-core communication;

[0061] Step 6: The computing core deployed on the vehicle central computing platform determines that the diagnostic service has been completed, puts its own Phy into sleep mode, and responds to the safety core to allow sleep mode.

[0062] Step 7: The security core deployed on the vehicle central computing platform receives the sleep confirmation information and puts all Phys of the vehicle Switch into sleep mode through the control bus; in this embodiment, it includes Phy1 / 2 / 3 / 4 of the vehicle Switch;

[0063] In the eighth step, the diagnostic instrument receives the sleep signal from the vehicle-mounted Switch, puts its own Phy into sleep mode, and enters sleep mode to achieve full-area sleep coordination of the vehicle.

[0064] like Figure 3 As shown, a vehicle-mounted high-performance computing platform Ethernet sleep / wake-up method, in which a regional controller triggers local sleep / wake-up, specifically includes the following steps:

[0065] In the first step, the regional controller generates a service request and wakes up its own Phy;

[0066] Specifically, the regional controller wakes up the on-board Switch through Phy and has the ability to remotely wake up the on-board central computing platform through Phy.

[0067] In the second step, the on-board switch of the on-board central computing platform receives the wake-up request from the regional controller, sets the activation line to valid, and notifies the security core of the wake-up request;

[0068] Specifically, the vehicle-mounted Switch sets the activation line to valid through the wake-up of Phy, realizes the wake-up of the security core, and has the ability to wake up the security core.

[0069] In the third step, the security core deployed on the vehicle central computing platform receives the wake-up request from the vehicle switch activation line, determines that the wake-up request comes from the regional controller, and notifies the computing core of the wake-up request through inter-core communication;

[0070] Step 4: The computing core deployed on the vehicle central computing platform confirms that the wake-up service is legal, wakes up its own Phy, and notifies the security core to confirm the wake-up;

[0071] Step 5: The security core deployed on the vehicle central computing platform receives the confirmation wake-up information from the computing core and wakes up the Phy of the vehicle switch through the control bus, including the Phy connected to the computing core and the Phy connected to the regional controller of the service request; this is a local wake-up;

[0072] In this embodiment, regional controller 1 and regional controller 2 are set. If the service request comes from regional controller 1, regional controller 2 continues to sleep, otherwise regional controller 1 continues to sleep, thereby realizing local wake-up coordination in the vehicle domain.

[0073] Step 6: After the regional controller completes the business processing, it initiates a sleep request to the vehicle-mounted central computing platform;

[0074] Step 7: The onboard Switch of the onboard central computing platform receives the sleep request from the regional controller and notifies the security core of the sleep request.

[0075] Step 8: The security core deployed on the vehicle central computing platform receives a sleep request from the vehicle switch activation line, determines that the sleep request comes from the regional controller, and notifies the computing core of the sleep request through inter-core communication.

[0076] In the ninth step, the computing core deployed on the vehicle central computing platform confirms that the business processing is completed, puts its own Phy into hibernation, and notifies the security core to confirm hibernation;

[0077] Step 10: The security core deployed on the vehicle central computing platform receives the confirmation sleep information from the computing core and sleeps the Phy of the vehicle switch through the control bus, including the Phy connected to the computing core and the Phy connected to the regional controller of the service request;

[0078] In the eleventh step, the Phy of the regional controller receives the sleep signal from the vehicle-mounted Switch, puts its own Phy into sleep mode, and realizes local sleep coordination in the vehicle domain.

[0079] For example, in this embodiment, the local sleep / wake-up is triggered by the regional controller 1, which specifically includes the following steps:

[0080] In the first step, regional controller 1 generates a service request and wakes up its own Phy;

[0081] In the second step, the vehicle-mounted Switch of the vehicle-mounted central computing platform receives the wake-up request from regional controller 1, sets the activation line to valid, and notifies the security core of the wake-up request;

This is a local wake-up; the regional controller 2 continues to sleep, realizing the local wake-up coordination of the vehicle domain.

[0085] Step 6: After completing the service processing, the regional controller 1 initiates a sleep request to the vehicle-mounted central computing platform;

[0086] Step 7: The onboard Switch of the onboard central computing platform receives the sleep request from regional controller 1 and notifies the security core of the sleep request.

[0087] Step 8: The security core deployed on the vehicle central computing platform receives a sleep request from the vehicle switch activation line, determines that the sleep request comes from regional controller 1, and notifies the computing core of the sleep request through inter-core communication;

[0088] In the ninth step, the computing core deployed on the vehicle central computing platform confirms that the business processing is completed, puts its own Phy into hibernation, and notifies the security core to confirm hibernation;

[0089] Step 10: The security core deployed on the vehicle central computing platform receives the sleep confirmation information from the computing core and sleeps Phy1 and Phy2 of the vehicle switch through the control bus;

[0090] In the eleventh step, the Phy of regional controller 1 receives the sleep signal from the vehicle-mounted Switch, puts its own Phy into sleep mode, and enters the sleep state to achieve local sleep coordination in the vehicle domain.
