It should be noted that the term "object" and the like in the description of the present invention and the claims and the above drawings are used for distinguishing between similar objects and not necessarily for describing a particular sequential or chronological order. It is to be understood that the data so used may be interchanged where appropriate such that the embodiments of the invention described herein may be implemented in sequences other than those illustrated or otherwise described herein. Furthermore, the terms "comprises," "comprising," and "includes," and any variations thereof, are intended to cover a non-exclusive inclusion, such that a process, method, system, article, or apparatus that comprises a list of steps or elements is not necessarily limited to those steps or elements expressly listed but may include other steps or elements not expressly listed or inherent to such process, method, article, or apparatus.

Fig. 1 is a flowchart of a whole vehicle energy saving control method provided according to an embodiment of the present application, where the present embodiment is applicable to an application scenario in which a vehicle usage scenario is identified based on a central computing and regional control architecture and an energy saving control is performed on a vehicle-mounted controller based on the vehicle usage scenario, and the method may be performed by a whole vehicle energy saving control device that may be configured in a vehicle having an intelligent driving function.

In the application, under the electronic electric architecture based on central computation and regional control, the functions of the whole vehicle are concentrated to a computing platform, and in the regional control platform (Power Data Center, PDC), elements such as an electronic fuse and an electronic switch are introduced to supply power to each vehicle-mounted controller ECU, so that the power supply control of the ECU according to scenes can be realized instead of the traditional fuses. Therefore, the whole vehicle energy-saving control based on the ECU can be realized.

As shown in fig. 1, the method includes:

s101, acquiring a user trigger vehicle-using signal and a vehicle mode signal.

The whole vehicle mode signal comprises the following components: a power mode signal and a vehicle mode signal. Typically, the power mode signal comprises: a generator power mode signal, a battery power mode signal, and a hybrid power mode signal; the vehicle mode signal includes: a factory mode signal, a test mode signal, and a driving mode signal.

In embodiments of the present invention, a user-triggered vehicle signal may refer to a user triggering use of a vehicle through a particular hardware module (e.g., for any vehicle controller or platform). Typically, the user-triggered vehicle signal may be a function command signal issued by the user according to the actual use requirement when the vehicle is in a powered-down sleep state. The hardware module for issuing the user trigger vehicle-using signal is the wake-up source.

Optionally, the user-triggered vehicle signal comprises at least one of: remote control vehicle command signals, OTA upgrade command signals, automatic driving command signals, and vehicle automatic monitoring or operation command signals.

The remote control vehicle command signal may be a remote start of the engine, a remote start of the air conditioner, or the like.

The Over-the-Air Technology (OTA) upgrade instruction signal may be an OTA timing upgrade.

The automatic driving instruction signal may be a proxy parking, and in this scenario, the user is not in the vehicle, and may consider cutting off power supply or communication of the ECU that does not need to operate.

The automatic monitoring or running command signal of the vehicle can be a sentry mode, automatic heating of the cockpit, dragging alarm and the like.

It should be noted that, in the sleep-wake scenario, all the vehicle-mounted controllers are not required to work like driving the vehicle, and the display requirements of the touch screen display and the external light are not required, and typically, the functional requirements of the user for driving the vehicle in the sleep-wake scenario include, but are not limited to: the vehicle is remotely controlled, such as the engine is remotely started or the vehicle is charged, so that the sleep wake-up scene can be used as a core scene of the whole vehicle energy-saving control. However, the technical scheme can be equally applied to the scene of the user using the vehicle, and the above proposal is only performed.

In the embodiment of the invention, the power mode signal and the vehicle mode signal can be used as global variables for identifying the working state of the whole vehicle, and the power mode signal and the vehicle mode signal can be transmitted to the whole vehicle energy-saving control module through different functional modules. Under different power mode signals, the energy-saving control strategy of the whole vehicle can be predefined to be started or not started, and under different power mode signals and vehicle mode signals, different use scenes and function requirements can be defined for the same wake-up source (such as any vehicle controller), so that corresponding use scenes and function requirements can be identified according to the user-triggered vehicle signals and the whole vehicle mode signals.

S102, determining a primary network according to a user-triggered vehicle signal and a whole vehicle mode signal.

The primary network is a backbone network segment which is awakened according to a user-triggered vehicle signal and a vehicle mode signal, and can be awakened by different awakening sources according to the awakening sources of the vehicle.

Fig. 2 is a schematic structural diagram of a whole vehicle computing platform according to an embodiment of the present invention. Referring to fig. 2, under the whole vehicle electronic and electric architecture based on central computing and regional control, the whole vehicle computing platform can be defined to include the following four platforms: the intelligent control platform (Vehicle Domain Controller, VDC), the intelligent sharing platform (Cockpit Space Center, CSC), the intelligent driving platform (High Automated Driving, HAD), the intelligent linkage platform (Intelligent Communication Controller, ICC), and the network management execution module arranged in the CSC, ICC, HAD is used for communication management among the platforms. The zone controller is typically designed with 3 to 4 platforms, including domain controlled platforms (Power Data Center, PDC) front/left/right/back. The backbone network section of the whole vehicle can be divided into 4 groups, which are respectively: one set of VDC and PDC, one set of VDC and ICC, one set of VDC and HAD, one set of VDC and CSC. The primary network may be any of the groups of network segments described above.

With continued reference to fig. 2, the vdc includes a power mode configuration module, a vehicle energy saving scenario module, and a scenario application module. The scene application program module can be used for receiving the instruction signals and judging whether the current functional scene and conditions are met. The whole vehicle energy-saving scene module can judge and decide a current network segment needing to be awakened according to a user trigger vehicle signal, and acquire a power supply mode signal, a vehicle mode signal and an instruction signal of a scene application program.

In this embodiment, the corresponding application scenario and function requirement may be identified according to the different user trigger vehicle signals and the whole vehicle mode signals, and the corresponding primary network may be awakened for the different vehicle scenario and function requirement. For example, when the vehicle scene and the function requirement are that the whole vehicle is required to work, the VDC and the PDC network segments can be awakened; when the vehicle scene and the function requirement are triggered by the dragging alarm function, ICC is a wake-up source, and the ICC can wake up the VDC and the ICC network segment, so that the VDC and the PDC network segment are wake-up by the VDC. After the primary network wakes up, the subsequent steps continue to be performed.

S103, determining a target scene mode according to the user-triggered vehicle-using signal.

The scene mode can be defined according to the user requirement in the design stage, and is stored and managed through a number or a preset list. The target scene mode is a user vehicle scene and functional requirements delivered by the wake source. In different scene modes, the ECUs that need to operate are different, and the operating modes of the ECUs are also different.

Typically, the target scene modes include, but are not limited to: remote starting air conditioning scene, remote charging scene, bus parking scene, cockpit heating scene and dragging alarm scene.

In this embodiment, an application program may be used to communicate with a wake-up source corresponding to a user-triggered vehicle signal, where the application program identifies the wake-up source of the user-triggered vehicle signal, receives a user vehicle scene and a function requirement transmitted by the wake-up source, determines a target scene mode according to the user vehicle scene and the function requirement, and sends the target scene mode to the whole vehicle energy-saving control module.

S104, determining a secondary network according to the target scene mode and the regional control framework, and issuing an energy-saving control instruction to a vehicle-mounted controller under the secondary network.

The regional control architecture is a network path and a power supply path of a controller constructed based on control regions and functions. The secondary network is a controller topology that participates in operation in the target scene mode. The energy-saving control instruction comprises: on the basis of the ECU powered by the B+, the ECU network needing to work is waken up to work, and the ECU which does not need to work is not dormant.

In this embodiment, the correspondence between the scene mode and the ECU participating in the work may be defined, managed and numbered in the design stage. Under different scene modes, the ECUs needing to work are different, and the working modes of the ECUs are different. The whole vehicle energy-saving scene module needs to maintain each vehicle type and configuration, and can store an ECU list, a network topology and a power supply topology of the vehicle type according to different vehicle types and different configurations. Meanwhile, the whole vehicle energy-saving scene module needs to preset an ECU list and working mode requirements needed by each functional scene, and meanwhile, a power supply path and a network path of each ECU can be obtained according to the network topology and the power supply topology.

As shown in fig. 2, the secondary network includes each network segment under the PDC, and because the ECU receives the PDC, when the target scene mode is implemented, the ECU under the PDC needs to be accurately controlled according to the regional and functional differences. For example, the PDC includes a front PDC, a rear PDC, a left PDC, and a right PDC, which are respectively used for supplying power to components and ECU of four areas and managing the network, and a corresponding power distribution execution module and network management execution module are provided. Illustratively, the VDC may communicate with the front PDC, the left PDC, the right PDC, the rear PDC via the CAN bus. According to PDC mounting position and whole vehicle function configuration, ECU arrangement position and function, generally front PDC is installed to front cabin, left PDC is installed to left cockpit, right PDC is installed to right cockpit, back PDC is installed in two rows of seats or back row luggage case, ECU inserts the network segment of different regional PDC nearby, can be equipped with headlight network segment, thermal management network segment under the front PDC.

Fig. 3 is a schematic structural diagram of PDC driving power distribution according to an embodiment of the present invention, and referring to fig. 2 and fig. 3, PDCs are a generic name of a front PDC, a left PDC, a right PDC, and a rear PDC, and ECUs include corresponding ECUs in a PDC control system. The PDCs include a power supply execution module and a power supply driving module, where the power supply driving module is configured to drive corresponding ECU power supply components to work, such as an electronic fuse (Efuse) or an electronic switch (e.g. Mos), and the power supply execution module is configured to supply power to the power supply driving module, so that a power supply path sent by an upper layer may be converted into a control instruction and the control instruction is transmitted to the power supply driving module.

For example, taking the user-triggered vehicle signal as a remote starting front light command, after receiving the user-triggered vehicle signal, a primary network that needs to be woken up by the user-triggered vehicle signal is identified according to a wake-up source of the user-triggered vehicle signal, for example, a wake-up source of the remote starting front light may be ICC, a corresponding primary network may be VDC and an ICC network segment, the ICC may wake up the VDC and the ICC network segment, and the VDC wakes up the VDC and the PDC network segment. After the primary network is determined, whether the working state of the whole vehicle meets the wake-up condition of the primary network can be judged by combining the power mode signal and the vehicle mode signal, for example, if the vehicle mode signal is a factory mode, the primary network is prohibited from being started remotely. If the working state of the whole vehicle meets the wake-up condition of the primary network, a wake-up source of a user trigger vehicle signal is adopted to wake up the primary network. After primary network awakening, an awakening source of a user triggering a vehicle signal is identified, a user vehicle scene and a function requirement transmitted by the awakening source are received, and a target scene mode is determined according to the user vehicle scene and the function requirement, for example, the target scene mode can be a remote starting front vehicle lamp. If the area control architecture is defined in the design stage: the left lamp ECU and the right lamp ECU of the front PDC participate in realizing remote starting of the front car lamp, and then the secondary network is as follows: left and right lamp ECUs of the front PDC. And the power distribution execution module and the network management execution module of the front PDC are sent to save energy control instructions, the left lamp ECU and the right lamp ECU are powered and driven, other ECUs hung under the front PDC are not electrified, and the energy saving control of the front PDC in a target scene mode is realized.

Therefore, the whole vehicle energy-saving control method provided by the embodiment of the invention has the advantages that the user trigger vehicle-using signal and the whole vehicle mode signal are obtained, the primary network is determined according to the user trigger vehicle-using signal and the whole vehicle mode signal, after the primary network is wakened, the wake-up source is identified according to the user trigger vehicle-using signal, the scene and the function requirement of the user vehicle transmitted by the wake-up source are received, the corresponding vehicle-mounted controller ECU and the function part are controlled to execute the scene mode of the corresponding function, and the vehicle-mounted controller in the non-target scene mode is powered according to the power supply of the vehicle-mounted controller required by the target scene mode, so that the whole vehicle energy-saving control based on the scene can be realized, and the energy consumption of the whole vehicle is reduced.

Fig. 4 is a flowchart of a whole vehicle energy-saving control method according to a first alternative embodiment provided by the embodiment of the present invention, and on the basis of fig. 1, a specific implementation manner of whole vehicle energy-saving control is shown.

It should be noted that, in the design stage, a plurality of preset scene lists can be defined according to the vehicle type and the vehicle configuration type, and when the target controller list is determined by looking up the table, the corresponding preset scene list can be called in combination with the vehicle type and the vehicle configuration type.

S205, inquiring a preset path table according to the name of the target controller, and determining a secondary network.

When entering a target scene mode, all ECUs in the secondary network are electrified; the target power supply path is used for representing a power supply path of the target controller, and when the target controller is started, the target controller can be controlled to be electrified according to the power supply path.

Typically, the preset network topology includes: at least one group of preset controller names and preset network paths, wherein the preset controller names and the preset network paths are in one-to-one correspondence.

The preset power supply topology is a power supply path of the controller under specific scenes, different vehicle types and vehicle configurations established through calibration. Typically, the preset power topology comprises: at least one group of preset controller names and preset power supply paths, wherein the preset controller names and the preset power supply paths are in one-to-one correspondence.

It should be noted that, in the calibration process, different preset network topologies and preset power supply topologies can be established according to different vehicle types and different vehicle configuration types.

Specifically, after the target scene mode is obtained, the vehicle model and the vehicle configuration type are combined, the target scene mode is compared with a preset scene in a preset scene list, and the controller name and the controller working mode in the same scene as the target scene mode are determined as the target controller name and the working mode requirement in the target controller list. And selecting a preset path table by combining the current vehicle type and the vehicle configuration parameters, comparing the name of the target controller working in the target scene mode with the name of the preset controller in the preset path table, determining a preset network path corresponding to the controller with the same name as the target controller in the preset network topology as a secondary network in the target scene mode, and determining a preset power supply path corresponding to the controller with the same name as the target controller in the preset power supply topology as a target power supply path in the target scene mode.

The vehicle condition may be a vehicle state parameter under a specific vehicle function, typically, the vehicle state parameter includes, but is not limited to: a State of Charge (SOC) condition, a power mode, and a vehicle mode. The preset activation condition is a preset whole vehicle state condition parameter for activating a specific scene function, and exemplary preset activation conditions can include, but are not limited to, a preset activation power state condition, a preset anti-theft state condition and a preset activation vehicle state condition.

The application program may obtain a wake-up source request and a user function requirement corresponding to the user trigger signal, and determine whether the overall vehicle function condition really meets the preset activation condition according to the wake-up source request. When the whole vehicle function condition meets the corresponding preset activation condition, the vehicle can be activated. For example, when SOC is less than or equal to 60%, the remote control function is not allowed to be started; when the vehicle mode is the factory mode, the remote function or the like is disabled.

Under different scenes, only specific ECU works to meet the minimum work requirement, the whole vehicle power consumption can be optimized, and the fine power consumption control under the central calculation and area architecture is realized.
