The timing task management unit 110 may receive a reservation function instruction of the mobile terminal 400, or may receive timing task instructions of the plurality of electronic control units 200 locally at the vehicle end, and may be a vehicle-end generalized timing task management unit. Either the local plurality of electronic control units 200 or the remote mobile terminal 400 needs to receive the input reservation task information such as timing time, notification party, power-up and wake-up parameters.

In an embodiment of the present application, the vehicle module 100 may communicate with the cloud server 500 through message queue telemetry transmission.
In particular, message queue telemetry transport (Message Queuing Telemetry Transport, MQTT) is a message protocol under the ISO standard (ISO/IEC PRF 20922) based on the publish/subscribe paradigm. It works on the TCP/IP protocol family and is a publish/subscribe message protocol designed for remote devices with low hardware performance and in poor network conditions. The MQTT protocol is lightweight, simple, open and easy to implement.

In the embodiment of the present application, the vehicle module 100 communicates with the plurality of electronic control units 200 and the in-vehicle controller 300 through an ethernet DDS and/or CAN network.
In particular, ethernet is a computer local area network technology, and as a core technology for network data communication, a data distribution service (Data Distribution Service, DDS) can reliably exchange and distribute group data in real time, and its transmission capacity is several orders of magnitude higher than that of a normal tactical data link. The DDS can ensure highly reliable data transmission with little time and without limiting the reporting amount capacity in the network. The controller area network bus (Controller Area Network, CAN) is a serial communication protocol bus for real-time applications that CAN be used for communication between different components in an automobile to replace expensive and heavy wiring harnesses. The features of the CAN protocol include serial data communication for integrity, providing real-time support, high transmission rates, etc. The data sent by the CAN network is sent to all the electronic control units, and the electronic control units needing to execute the corresponding operation after receiving the information. The DDS is used for directionally transmitting information, and can directionally transmit the information to a corresponding electronic control unit. Preferably, in the embodiment of the present application, other information may be communicated through the ethernet DDS, except that the wake-up information is sent through the CAN network. In this way, the corresponding electronic control unit can be more efficiently powered on, awakened and the reservation task information is transmitted.
In the embodiment of the present application, the reservation task information may include:
task ID, task operation, timing time, power-on information, wake-up information, notifier ID, task content, and time stamp.
Specifically, the timed task management unit 110 is generalized to an externally provided interface, and the reserved task information transmitted from the mobile terminal 400 or the plurality of electronic control units 200 received by the timed task management unit 110 may include a plurality of parameters. The ID of each reservation task has a uniqueness, and in addition to adding a task, a task ID of the current reservation task needs to be input. The task operation refers to a specific operation of a currently reserved task. In an embodiment of the present application, the task operations may include: adding tasks, deleting tasks, modifying tasks and querying tasks. That is, the timed task management unit in the embodiments of the present application may support add, delete, modify, and query tasks. The timing time refers to execution time of a reservation task. The power-on information refers to which electronic control unit needs to be powered on normally and high voltage before the reservation task is executed, and the duration of power-on normally. The wake-up information is network management message information of which electronic control unit needs to be waken up before the reservation task is executed. The notifier ID is ID information of the target electronic control unit, so that when the timing time arrives, it is possible to know which electronic control unit needs to be notified to execute the corresponding function. The task content is specific task content which is required to be executed by the corresponding electronic control unit after the appointed time arrives. The timestamp refers to the latest operation time of the currently reserved task. Each corresponding element can be made aware of specific reservation information through reservation task information, so that corresponding operations are performed.
In an embodiment of the present application, the timed task management unit 110 may be further configured to:
after receiving and storing reservation task information, starting local timing and entering a dormant state;
performing self-waking operation according to a preset frequency and inquiring a task information list;
in the case that it is determined that the task reaching the timing time exists in the task information list, transmitting power-on information to the in-vehicle controller 300 and transmitting a network management message to the first target electronic control unit;
if it is determined that there is no task in the task information list that reaches the timing time, the sleep state is continued.
Specifically, the timed task management unit 110 may store the received reservation task information and start timing locally. During the time, the vehicle module 100 and the plurality of electronic control units 200 at the vehicle end may sleep normally. Since it is not known whether the time reaches the timing time of the reservation task during the sleep of the in-car module 100. Accordingly, the in-vehicle module 100 needs to perform a self-wake operation during sleep. The car machine module 100 performs a natural wake-up operation according to a frequency preset by a user, that is, a preset frequency, and queries a task information list. In the case that it is determined that there is no task reaching the timing time in the task information list, that is, the timing time of the reserved task is not reached at present, the vehicle immediately sleeps, and there is no need to send a network management message awakened by the vehicle machine module 100 to the outside. Under the condition that the task reaching the timing time exists in the task information list, namely the timing time reaching the reserved task currently, the power-on information is firstly input to the whole vehicle power management module of the vehicle-mounted controller 300, so that the power management module powers on normal electricity and high voltage electricity to the corresponding electronic control unit according to the power-on information, and then sends a network management message according to the wake-up information to wake up the corresponding electronic control unit. After the corresponding electronic control unit wakes up, the task content of the reserved task is notified to the first target electronic control unit in a mode of using a message through an Ethernet DDS or a CAN network, so that the first target electronic control unit CAN execute the corresponding function according to the task content.
