Referring to fig. 1, an embodiment of the present disclosure provides a timing management apparatus of a vehicle. The timing management device is deployed in a first domain controller of the vehicle and comprises a timing server and a timing module. The timing management apparatus may provide timing management services for a plurality of timing clients in the vehicle, which may be deployed in a plurality of domain controllers of the vehicle.
The timing server is used for receiving timing information of the timing tasks sent by the timing client and controlling the timing module to time according to the timing information of the timing tasks.
The timing module is used for sending an arrival reminding about the timing task to the timing server when timing time of the timing task is counted.
And the timing server is used for sending notification information of the timing time reaching the timing task to the timing client corresponding to the timing task when receiving the arrival reminding about the timing task so as to trigger the timing client corresponding to the timing task to execute the timing task.
According to one embodiment of the invention, a timing service may be deployed in a first domain controller of a vehicle to provide timing services for a plurality of domain controllers on the vehicle. According to one embodiment of the invention, the timing tasks of each domain controller are uniformly managed through the timing server, and a plurality of timing clients are supported to set the timing tasks simultaneously.
According to one embodiment of the present invention, the timing server may be disposed in an MPU of the first domain controller, and the timing client may be disposed in an MPU of the domain controller of the vehicle. The timing service end is arranged in the MPU of the first domain controller, and the powerful calculation support of the MPU is utilized to provide services for a plurality of timing clients, so that unified management of timing tasks of each domain controller is realized. By arranging the timing service end in the MPU of the first domain controller, the performance of the MCU of the first domain controller is not affected, and the high real-time performance of the MCU of the first domain controller is ensured.
According to one embodiment of the invention, the timing client may be created by a service Application (APP). When a service Application (APP) of a certain domain controller of the vehicle wants to use the timing service, the timing client is directly created to directly communicate with the timing service.
According to the embodiment of the invention, the timing service end can be deployed in the first domain controller of the vehicle to provide timing service for a plurality of domain controllers on the vehicle, and the timing service end and the timing client end are deployed in MPUs of the respective domain controllers, so that the application with timing requirements on each domain controller can directly call the timing service end based on communication between the MPUs.
According to the embodiment of the invention, the clock module is deployed in the MCU of the first domain controller by utilizing the characteristics of strong instantaneity and low power consumption of the MCU, and can perform timing task timing based on the clock chip of the MCU of the first domain controller, so that the timing management device has strong instantaneity and low power consumption.
In one embodiment, the timing server adds the timing task information to the timing task information list when receiving timing information of the timing task sent by the timing client. When receiving an arrival reminding about a timing task sent by a timing module, a timing server identifies the timing task of which timing client the arrival reminding aims at according to a timing task information list, and sends notification information of timing time reaching the timing task to the timing client corresponding to the timing task so as to trigger the timing client corresponding to the timing task to execute the timing task. In one example, a persisted list of timed task information may be employed to avoid loss of timed task information.
According to the embodiment of the invention, the timing tasks of each domain controller can be uniformly managed through the timing server, so that a plurality of timing servers can be supported to set the timing tasks simultaneously.
In one embodiment, the first domain controller is a domain controller responsible for vehicle external communications. Referring to fig. 2, the first domain controller may be a TCAM domain controller.
In a vehicle, a domain controller responsible for external communication of the whole vehicle generally does not sleep, and the domain controller responsible for external communication of the whole vehicle is used as a timing management device in the embodiment of the disclosure to be more reliable and not to additionally increase power consumption of the whole vehicle. In addition, the embodiment of the disclosure uses the domain controller responsible for the external communication of the whole vehicle as the timing management device, so that the timing management device has the capability of communicating with the server.
In one embodiment, referring to FIG. 1, at least one first timing client is included in the plurality of timing clients. The first timing client is deployed in an MPU of a second domain controller of the vehicle, the second domain controller being a different domain controller in the vehicle than the first domain controller. For example, referring to fig. 2, the first domain controller is a TCAM domain controller of a vehicle, one first timing client is provided in an MPU of a BDCM domain controller of the vehicle, and the other first timing client is provided in an MPU of a CDC domain controller of the vehicle.
In one embodiment, the MPU of the first domain controller and the MPU of the second domain controller are connected based on a first communication protocol to enable transfer of information between the timing server and the first timing client. That is, the timing information of the timing task of the first timing client and the notification information of the timing time of the timing task reaching the first timing client are directly transmitted between the MPU of the first domain controller and the MPU of the second domain controller without going through the MCU.
In one embodiment, the timing server is further configured to, when receiving an arrival reminding about a timing task of the first timing client, send, by the MCU of the first domain controller, a wake-up message to the MCU of the second domain controller where the first timing client is located, so as to wake up the second domain controller where the first timing client is located, so that the second domain controller after being woken up can execute the timing task.
For example, after receiving the arrival reminding about the timing task sent by the timing module, the timing server identifies which timing task of the first timing client is through the persistent timing task information list, and the MCU controlling the first domain controller sends a CAN network wake-up message to the MCU of the second domain controller where the first timing client is located through the CAN wake-up capability interface thereof, so as to wake up the second domain controller where the first timing client is located.
By the method, the second domain controller can still sleep under the condition that the timing task exists, the timing server side wakes up the second domain controller when the timing task of the second domain controller arrives, and the first timing client side of the second domain controller can receive the notification information of the timing time of the timing task sent by the timing server side, so that the timing task is executed. The design is beneficial to reducing the power consumption of the whole vehicle, and the second domain controller is not required to be continuously maintained in a working state with high power consumption.
In one embodiment, referring to FIG. 1, the plurality of timing clients includes at least one second timing client disposed in the MPU of the first domain controller. That is, the second timing client is provided in the first domain controller, and the timing server in the first domain controller may provide services for the second timing client in the first domain controller. Referring to fig. 2, the first domain controller is a TCAM domain controller of the vehicle, the timing server and the second timing client are disposed in an MPU of the first domain controller, and the timing module is disposed in an MCU of the first domain controller.
The second timing client is used for receiving the timing task issued by the server and sending timing information of the timing task issued by the server to the timing server. In this way, the timing server can provide services for the timing tasks issued by the server, so that the second timing client can execute the timing tasks issued by the server. In one example, referring to fig. 2, where the server communicates with the gateway based on the gRPC/HTTP network protocol, the gateway communicates with the second timing client via the MQTT network protocol, the server may issue timing tasks to the second timing client via the gateway.
In this embodiment, the first domain controller may be the domain controller responsible for the vehicle external communications such that the second timing client may receive timing tasks from the server using its communications capabilities without going through other domain controllers in the vehicle. In addition, in this way, when the vehicle receives the timing task issued by the server, the timing server triggers the second timing client to execute the timing task, and whole vehicle wake-up is not required.
As can be seen from fig. 1 and fig. 2, the timing server of the first domain controller and the first timing client of the second domain controller are both deployed in respective MPUs, and can interact based on the first communication protocol. The timing module of the first domain controller is disposed in the MCU, and the MCU of the first domain controller and the MCU of the second domain controller can interact based on a second communication protocol. The first communication protocol is for example an ethernet communication protocol and the second communication protocol is for example a CAN communication protocol.
The timing server side of the first domain controller and the first timing client side of the second domain controller are deployed in respective MPUs and interact based on the first communication protocol, and the situation that protocol conversion is required to be carried out between the first communication protocol and the second communication protocol on signals can be reduced without being transferred through an MCU, so that the communication link is simpler and more stable, and data are not easy to lose.
In one embodiment, the timing server is configured to determine a target timing task according to timing times of the plurality of timing tasks, and control the timing module to perform timing according to timing information of the target timing task. The target timing task is the task with the earliest timing time in the plurality of timing tasks.
That is, the timing server only controls the timing module to count the earliest timing time each time, and when the timing time of the timing module is up, the earliest timing time is determined again to control the timing module to start the next timing.
In one embodiment, the timing server screens the first time-arriving timing task of all the timing tasks as a target timing task, and configures the timing module according to the timing information of the target timing task, so that the timing module counts the target timing task in a countdown mode, and sends a time-arriving reminder to the timing server when the countdown is finished.
By means of the method, the timing service end performs unified management on all timing tasks, only controls the timing module to time the earliest timing task each time, and can reduce timing processing pressure of the timing module and prevent timing errors.
In one embodiment, the timing server is further configured to delete timing information of the timing task and control the timing module to terminate timing on the timing task when receiving a notification that the timing client cancels the timing task.
In one embodiment, the timing server is further configured to broadcast a timing task information list in the vehicle, so that each domain controller can directly learn timing task information submitted to the timing server by itself. For example, the timing server broadcasts a timing task information list based on the ethernet network of the vehicle.

In the embodiment of the disclosure, the timing module can be deployed in the MCU of the first domain controller, and is used for timing by using a clock chip in the MCU to support timing reminding.

In step S205, the timing server sends, to the first timing client, notification information of a timing time for reaching the first timing task based on ethernet, so as to trigger the first timing client to execute the first timing task.
In an embodiment of the present disclosure, the first timing client is disposed in an MPU of a second domain controller of the vehicle, the second domain controller being a different domain controller in the vehicle than the first domain controller.
