Description

Technical Field

[0001] This application relates to the field of electric vehicle technology, specifically designing a timing management system and timing management method for electric vehicles. Background Technology

[0002] With the rapid development of vehicle networking technology, users are no longer satisfied with on-site operation of the vehicle and also require remote control of the vehicle. In particular, with the emergence of new energy vehicles, the demand for remote or local reservation functions is increasing, such as scheduled charging, scheduled control of air conditioning, and scheduled heating.

[0003] Currently, most remote reservation functions involve scheduling charging and upgrades. Existing technologies can manage reservation tasks through cloud servers. For example, a scheduled charging plan can be generated on the cloud server based on the charging status of the target charging station, and the vehicle can be scheduled to start charging at regular intervals. Alternatively, the function can be managed through a controller on the vehicle. For instance, an onboard wireless charging system can store the scheduled charging information after receiving a remote control command and schedule the vehicle to start charging at regular intervals. However, for the first method, as the number of vehicles connected to the cloud server increases, server resource consumption increases significantly, leading to high costs. For the second method, the controller on the vehicle needs to be continuously powered and manage reservation tasks. Furthermore, as the number of reservation functions increases, the number of similar controllers will also increase, hindering vehicle power management and the generalization of reservation task management. Therefore, existing technologies for reservation management of electric vehicles are complex, costly, and inefficient. Summary of the Invention

[0004] The purpose of this application is to provide a timed management system and method for electric vehicles, in order to solve the problems that the reservation management of electric vehicles in the prior art is relatively complex, costly and inefficient.

[0005] To achieve the above objectives, a first aspect of this application provides a timing management system for an electric vehicle, the timing management system comprising:

[0006] The vehicle infotainment module includes a timed task management unit, which is configured to receive and store scheduled task information sent by a mobile terminal and / or multiple electronic control units, and to send power-on information to the vehicle controller and network management messages to the first target electronic control unit according to the scheduled task information.

[0007] The mobile terminal communicates with the vehicle's infotainment module via a cloud server and is configured to send reservation task information to the vehicle's infotainment module.

[0008] Multiple electronic control units communicate with the vehicle infotainment module and are configured to send reservation task information to the vehicle infotainment module and execute reservation tasks according to network management messages sent by the timed task management unit;

[0009] The vehicle controller communicates with the vehicle infotainment module and multiple electronic control units, and is configured to receive power-on information sent by the vehicle infotainment module and power on the second target electronic control unit according to the power-on information.

[0010] In this embodiment, the vehicle-mounted module and the cloud server communicate via message queue telemetry transmission.

[0011] In this embodiment, the vehicle module communicates with multiple electronic control units and the vehicle controller via Ethernet DDS and / or CAN networks.

[0012] In this embodiment of the application, the scheduled task information includes:

[0013] Task ID, task operation, timer, power-on information, wake-up information, notification party ID, task content, and timestamp.

[0014] In this embodiment of the application, the task operation includes:

[0015] Add a task, delete a task, modify a task, and query a task.

[0016] In this embodiment of the application, the scheduled task management unit is further configured to:

[0017] After receiving and storing the scheduled task information, it starts local timing and enters sleep mode;

[0018] Perform self-wake-up operation at a preset frequency and query the task information list;

[0019] If a task is found in the task information list that has reached its scheduled time, a power-on message is sent to the vehicle controller and a network management message is sent to the first target electronic control unit.

[0020] In this embodiment of the application, the scheduled task management unit is further configured to:

[0021] If no task in the task information list reaches its scheduled time, the system will continue to enter sleep mode.

[0022] A second aspect of this application provides a timing management method for an electric vehicle, applied to a timing task management unit. The timing task management unit is located in an in-vehicle infotainment module, which communicates with a mobile terminal, multiple electronic control units, and an in-vehicle controller. The timing management method includes:

[0023] Receive and store reservation task information sent by mobile terminals and / or multiple electronic control units;

[0024] According to the scheduled task information, a power-on message is sent to the vehicle controller, so that the vehicle controller can power on the second target electronic control unit according to the power-on message.

[0025] A network management message is sent to the first target electronic control unit so that the first target electronic control unit can execute the scheduled task according to the network management message.

[0026] In this embodiment of the application, the timing management method further includes:

[0027] After receiving and storing the scheduled task information, it starts local timing and enters sleep mode;

[0028] Perform self-wake-up operation at a preset frequency and query the task information list;

[0029] If a task is found in the task information list that has reached its scheduled time, a power-on message is sent to the vehicle controller and a network management message is sent to the first target electronic control unit.

[0030] In this embodiment of the application, the timing management method further includes:

[0031] If no task in the task information list reaches its scheduled time, the system will continue to enter sleep mode.

[0032] The beneficial effects of this application are:

[0033] By setting up a scheduled task management unit in the vehicle's infotainment module, a long-term communication channel is established not only with the cloud server but also with multiple electronic control units (ECUs) and onboard controllers. This allows the scheduled task management unit to receive both scheduled task information from mobile terminals and scheduled tasks from the vehicle's local ECUs. Upon the scheduled time, the unit powers on and wakes up the corresponding ECU and notifies it to execute the scheduled task. This enables standardized management of scheduled tasks, eliminating the need for multiple controllers to execute tasks separately. This reduces server resource consumption and costs, simplifies electric vehicle scheduling, and improves the efficiency of scheduled task execution.

[0043] Figure 1 This diagram schematically illustrates a structural diagram of a timing management system for an electric vehicle according to an embodiment of this application. Figure 1 As shown in the figure, this application embodiment provides a timing management system for an electric vehicle, which may include:

[0044] The vehicle infotainment module 100 includes a timed task management unit 110, which is configured to receive and store scheduled task information sent by a mobile terminal and / or multiple electronic control units 200, and to send power-on information to the vehicle controller 300 and send network management messages to the first target electronic control unit according to the scheduled task information.

[0045] The mobile terminal 400 communicates with the vehicle module 100 through the cloud server 500 and is configured to send reservation task information to the vehicle module 100.

[0046] Multiple electronic control units 200 communicate with the vehicle infotainment module 100 and are configured to send reservation task information to the vehicle infotainment module 100 and execute reservation tasks according to network management messages sent by the timed task management unit 110.

[0047] The vehicle controller 300 communicates with the vehicle infotainment module 100 and multiple electronic control units 200 respectively, and is configured to receive power-on information sent by the vehicle infotainment module 100 and power on the second target electronic control unit according to the power-on information.

[0048] This application provides a timing management system for an electric vehicle. The system may include a vehicle infotainment module 100, multiple electronic control units (ECUs) 200, an on-board controller 300, a mobile terminal 400, and a cloud server 500. The vehicle infotainment module 100 communicates with the multiple ECUs 200, the on-board controller 300, and the cloud server 500, respectively. The cloud server 500 communicates with the mobile terminal 400. In other words, the vehicle infotainment module 100 can communicate with the mobile terminal 400 through the cloud server 500.

[0049] In this embodiment, the vehicle infotainment module 100 can be a 4G or 5G module. A timed task management unit 110 is provided within the vehicle infotainment module 100. This timed task management unit 110 can establish a long-term communication channel with the cloud server 500 through the vehicle infotainment module 100, and can also establish Ethernet and / or CAN network communication channels with multiple electronic control units 200 and the vehicle controller 300, thereby enabling scheduled tasks for multiple electronic control units 200 of the electric vehicle. The timed task management unit 110 can receive scheduled function commands from the mobile terminal 400, and can also receive scheduled task commands from multiple local electronic control units 200 in the vehicle, becoming a universal timed task management unit for the vehicle. Whether it is the local multiple electronic control units 200 or the remote mobile terminal 400, they all need to receive the input scheduled task information such as the time, notification party, power-on and wake-up parameters. After the scheduled time arrives, the timed task management module 110 powers on and wakes up the corresponding electronic control unit, and notifies the corresponding first target electronic control unit to execute the scheduled task by sending a network management message. Among them, the first target electronic control unit refers to the electronic control unit that performs the scheduled task.

[0050] In this embodiment, the vehicle may include multiple electronic control units 200, such as an electronic control unit for scheduling air conditioning operation, an electronic control unit for scheduling charging, etc. These multiple electronic control units 200 communicate with the vehicle infotainment module 100 and can send scheduling task information to the vehicle infotainment module 100. After receiving a network management message sent by the timed task management unit 110 of the vehicle infotainment module 100, the corresponding scheduling task can be executed according to the network management message.

[0051] In this embodiment, the vehicle controller 300 communicates with the vehicle infotainment module 100 and multiple electronic control units 200. The vehicle controller 300 can receive power-on information sent by the vehicle infotainment module 100 and power on the second target electronic control unit according to the power-on information. The second target electronic control unit refers to the electronic control unit that needs to be power-on and woken up. The electronic control unit that needs to be power-on and woken up and the electronic control unit that needs to perform the scheduled task can be the same or different. The power-on information can include the ID of the specific target electronic control unit, thereby enabling the corresponding target electronic control unit to perform the corresponding operation.

[0052] In this embodiment, the vehicle infotainment module 100 can also communicate with the cloud server 500, and the cloud server 500 communicates with the mobile terminal 400. Therefore, the mobile terminal 400 can communicate with the vehicle infotainment module 100 through the cloud server 500. After the user sets reservation task information on the mobile terminal 400, the mobile terminal 400 can send the reservation task information to the vehicle infotainment module 100 through the cloud server 500. The vehicle infotainment module 100 then performs corresponding operations based on the received reservation task information.

[0053] This embodiment establishes a scheduled task management unit in the vehicle's infotainment module. This unit not only establishes a long-term communication channel with the cloud server but also with multiple electronic control units (ECUs) and the vehicle's onboard controller. This allows the scheduled task management unit to receive both scheduled task information from mobile terminals and scheduled tasks from the vehicle's local ECUs. Upon the scheduled time, the unit powers on and wakes up the corresponding ECU and notifies it to execute the scheduled task. This enables standardized management of scheduled tasks, eliminating the need for multiple controllers to execute tasks separately. This reduces server resource consumption and costs, simplifies electric vehicle scheduling, and improves the efficiency of scheduled task execution.

[0054] In this embodiment of the application, the vehicle-mounted module 100 can communicate with the cloud server 500 via message queue telemetry transmission.

[0055] Specifically, Message Queuing Telemetry Transport (MQTT) is a publish / subscribe messaging protocol based on the ISO standard (ISO / IEC PRF 20922). It operates on the TCP / IP protocol suite and is designed for remote devices with limited hardware performance and poor network conditions. The MQTT protocol is lightweight, simple, open, and easy to implement. MQTT transmission enables the vehicle's infotainment module 100 to better receive remotely scheduled task information.

[0056] In this embodiment, the vehicle module 100 communicates with multiple electronic control units 200 and the vehicle controller 300 via Ethernet DDS and / or CAN networks.

[0057] Specifically, Ethernet is a computer local area network (LAN) technology. Data Distribution Service (DDS), as the core technology of network data communication, can reliably and in real-time exchange and distribution of group data, with a transmission capacity several orders of magnitude higher than typical tactical data links. DDS can ensure highly reliable data transmission in minimal time and without limiting the number of reports in the network. Controller Area Network (CAN) is a serial communication protocol bus for real-time applications, used for communication between different components in a vehicle, replacing expensive and bulky wiring harnesses. CAN protocol features include complete serial data communication, real-time support, and high transmission rates. Data sent via the CAN network is sent to all electronic control units (ECUs), and the ECUs that need to perform corresponding operations execute the corresponding operations upon receiving the information. DDS, on the other hand, sends information in a targeted manner, directing information to the corresponding ECU. Preferably, in this embodiment, except for wake-up information sent via the CAN network, all other information can be communicated via Ethernet DDS. This allows for more efficient power-on, wake-up, and sending of scheduled task information to the corresponding ECUs.

[0058] In this embodiment of the application, the scheduled task information may include:

[0059] Task ID, task operation, timer, power-on information, wake-up information, notification party ID, task content, and timestamp.

[0060] Specifically, the interface provided by the scheduled task management unit 110 is universal. The scheduled task management unit 110 receives reservation task information sent by the mobile terminal 400 or multiple electronic control units 200, which may include multiple parameters. Each reservation task ID is unique; except for adding a task, the task ID of the current reservation task must be entered. Task operation refers to the specific operation of the current reservation task. In this embodiment, task operation may include: adding a task, deleting a task, modifying a task, and querying a task. That is, the scheduled task management unit in this embodiment can support adding, deleting, modifying, and querying tasks. Scheduled time refers to the execution time of the reservation task. Power-on information refers to which electronic control unit needs to be powered on with constant power and high voltage before the reservation task is executed, and the duration of constant power-on. Wake-up information refers to the network management message information of which electronic control unit needs to be woken up before the reservation task is executed. Notifier ID is the ID information of the target electronic control unit, so that when the scheduled time arrives, it can be known which electronic control unit needs to be notified to perform the corresponding function. Task content refers to the specific task content that the corresponding electronic control unit needs to perform after the scheduled time arrives. Timestamp refers to the latest operation time of the current reservation task. By using the appointment task information, each corresponding component can be informed of the specific appointment details, thereby enabling it to perform the corresponding operation.

[0061] In this embodiment of the application, the timed task management unit 110 can also be configured to:

[0062] After receiving and storing the scheduled task information, it starts local timing and enters sleep mode;

[0063] Perform self-wake-up operation at a preset frequency and query the task information list;

[0064] If a task in the task information list has reached its scheduled time, a power-on message is sent to the vehicle controller 300 and a network management message is sent to the first target electronic control unit.

[0065] If no task in the task information list reaches its scheduled time, the system will continue to enter sleep mode.

[0066] Specifically, the scheduled task management unit 110 can store the received scheduled task information and start timing locally. During the timing period, the vehicle infotainment module 100 and multiple electronic control units 200 on the vehicle side can all go into sleep mode normally. Since it is impossible to know whether the scheduled time of the scheduled task has been reached during the sleep period of the vehicle infotainment module 100, the vehicle infotainment module 100 needs to perform a self-wake-up operation during the sleep period. The vehicle infotainment module 100 performs a natural wake-up operation according to the frequency preset by the user, i.e., the preset frequency, and queries the task information list. If it is determined that there is no task in the task information list that has reached the scheduled time, i.e., the scheduled time of the task has not been reached, it immediately goes into sleep mode without sending a network management message to wake up the vehicle infotainment module 100. If it is determined that there is a task in the task information list that has reached the scheduled time, i.e., the scheduled time of the task has been reached, it first inputs power-on information to the vehicle power management module of the vehicle controller 300, so that the power management module supplies constant power and high voltage to the corresponding electronic control unit according to the power-on information, and then sends a network management message to wake up the corresponding electronic control unit according to the wake-up information. Once the corresponding electronic control unit is awakened, the task content of the scheduled task is notified to the first target electronic control unit via Ethernet DDS or CAN network application messages, so that the first target electronic control unit can perform the corresponding function according to the task content.

[0067] Figure 2 A flowchart illustrating a timing management method for an electric vehicle according to an embodiment of this application is shown schematically. Figure 2 As shown in the embodiments of this application, a timing management method for electric vehicles is provided, applied to... Figure 1 The timed task management unit 110 is located in the vehicle infotainment module. The vehicle infotainment module communicates with a mobile terminal, multiple electronic control units, and an in-vehicle controller. The timed task management method may include the following steps:

[0068] Step 201: Receive and store the reservation task information sent by the mobile terminal and / or multiple electronic control units;

[0069] Step 202: Send power-on information to the vehicle controller according to the scheduled task information, so that the vehicle controller can power on the second target electronic control unit according to the power-on information;

[0070] Step 203: Send a network management message to the first target electronic control unit so that the first target electronic control unit can execute the scheduled task according to the network management message.

[0071] This application provides a timing management method for an electric vehicle. This method, applied to the aforementioned timing management system for an electric vehicle, may include a vehicle-mounted module, multiple electronic control units (ECUs), an on-board controller, a mobile terminal, and a cloud server. The vehicle-mounted module communicates with the multiple ECUs, the on-board controller, and the cloud server, while the cloud server communicates with the mobile terminal. In this application, the vehicle-mounted module can be a 4G or 5G module. A timing task management unit is provided within the vehicle-mounted module. This unit can establish a long-term communication channel with the cloud server via the vehicle-mounted module, and also establish Ethernet and / or CAN network communication channels with the multiple ECUs and the on-board controller, thereby enabling the scheduling of multiple ECUs for timed functions.

[0072] In this implementation, the scheduled task management unit can receive reservation function commands from mobile terminals, as well as scheduled task commands from multiple local electronic control units (ECUs) on the vehicle, thus becoming a universal scheduled task management unit on the vehicle side. Whether it's multiple local ECUs or a remote mobile terminal, both need to receive input reservation task information such as the timing time, the notifying party, and power-on and wake-up parameters. After the scheduled time arrives, the scheduled task management module powers on and wakes up the corresponding second target ECU, and notifies the corresponding first target ECU to execute the scheduled task by sending a network management message. Here, the first target ECU refers to the ECU executing the scheduled task; the second target ECU refers to the ECU that is powered on and woken up.

[0073] In this embodiment, the vehicle may include multiple electronic control units (ECUs), such as an ECU for scheduling air conditioning operation and an ECU for scheduling charging. These ECUs communicate with the vehicle infotainment module and can send scheduling task information to the module. Upon receiving a network management message from the vehicle infotainment module's timed task management unit, the corresponding scheduling task can be executed based on the network management message. In this embodiment, the vehicle controller communicates with both the vehicle infotainment module and the multiple ECUs. The vehicle controller can receive power-on information from the vehicle infotainment module and power on the second target ECU based on this information. The ECU requiring power-on wake-up and the ECU requiring the scheduling task can be the same or different. The power-on information may include the ID of the specific target ECU, enabling the corresponding target ECU to perform the corresponding operation.

[0074] In this embodiment, the vehicle infotainment module can also communicate with the mobile terminal via a cloud server. Therefore, the mobile terminal can communicate with the vehicle infotainment module through the cloud server. After the user sets reservation task information on the mobile terminal, the mobile terminal can send the reservation task information to the vehicle infotainment module through the cloud server. The vehicle infotainment module then performs corresponding operations based on the received reservation task information.

[0075] This embodiment establishes a scheduled task management unit in the vehicle's infotainment module. This unit not only establishes a long-term communication channel with the cloud server but also with multiple electronic control units (ECUs) and the vehicle's onboard controller. This allows the scheduled task management unit to receive both scheduled task information from mobile terminals and scheduled tasks from the vehicle's local ECUs. Upon the scheduled time, the unit powers on and wakes up the corresponding ECU and notifies it to execute the scheduled task. This enables standardized management of scheduled tasks, eliminating the need for multiple controllers to execute tasks separately. This reduces server resource consumption and costs, simplifies electric vehicle scheduling, and improves the efficiency of scheduled task execution.

[0076] In this embodiment of the application, the timing management method may further include:

[0077] After receiving and storing the scheduled task information, it starts local timing and enters sleep mode;

[0078] Perform self-wake-up operation at a preset frequency and query the task information list;

[0079] If a task in the task information list has reached its scheduled time, a power-on message is sent to the vehicle controller and a network management message is sent to the first target electronic control unit.

[0080] If no task in the task information list reaches its scheduled time, the system will continue to enter sleep mode.

[0081] Specifically, the scheduled task management unit can store the received scheduled task information and start timing locally. During the timing period, the vehicle infotainment module and multiple electronic control units (ECUs) on the vehicle can normally go into sleep mode. Since it is impossible to know whether the scheduled task time has been reached during the vehicle infotainment module's sleep period, the vehicle infotainment module needs to perform a self-wake-up operation during sleep. The vehicle infotainment module performs a natural wake-up operation according to the user-preset frequency and queries the task information list. If it determines that there is no task in the task information list that has reached its scheduled time, that is, the scheduled task time has not been reached, it immediately goes into sleep mode without sending a network management message to wake up the vehicle infotainment module. If it determines that there is a task in the task information list that has reached its scheduled time, that is, the scheduled task time has been reached, it first inputs power-on information to the vehicle power management module of the vehicle controller. The power management module then supplies constant power and high voltage to the corresponding ECU based on the power-on information, and then sends a network management message to wake up the corresponding ECU based on the wake-up information. Once the corresponding electronic control unit is awakened, the task content of the scheduled task is notified to the first target electronic control unit via Ethernet DDS or CAN network application messages, so that the first target electronic control unit can perform the corresponding function according to the task content.

[0083] S01, ECU or cloud server send scheduled tasks, input task information to the scheduled task management unit;

[0084] S02. The timed task management unit stores the task information and starts the timer.

[0085] S03. When the scheduled time arrives, the timed task management unit powers on and wakes up the ECU;

[0086] S04. The timed task management unit sends a notification task information to the ECU.

[0087] S05, the ECU executes functions based on task information.

[0088] In one specific embodiment of this application, a communication channel is established between the scheduled task management unit, the cloud server, and multiple electronic control units (ECUs). This allows the scheduled task management unit to receive both scheduled task information from mobile terminals and scheduled tasks from local ECUs in the vehicle. Upon the scheduled time, the scheduled task management unit powers on and wakes up the corresponding ECU and notifies it to execute the scheduled task information. This enables universal management of scheduled tasks, eliminating the need for multiple controllers to execute tasks separately, reducing server resource consumption and costs, simplifying electric vehicle scheduling, and improving the efficiency of scheduled task execution.
