The following describes the energy management method shown in fig. 1, which includes the following specific steps:
s101, acquiring a current state signal of the vehicle.
In this step, the vehicle-mounted terminal acquires a current state signal of the vehicle. For example, the current status signal of the vehicle may be acquired via the CAN bus.
In some embodiments, the status signal comprises one or more of a power state signal, a vehicle driving state signal, a vehicle electrical state signal, an environmental signal, wherein the power state signal comprises a power battery state of charge signal and/or a power mode signal, the vehicle driving state signal comprises one or more of an output state signal of a DC converter/generator, an output power signal of a DC converter/generator, a temperature signal of a DC converter/generator, the vehicle electrical state signal comprises an electrical consumer power signal, and the environmental signal comprises a collision signal and/or a power battery thermal runaway signal.

Alternatively, the state signal of the vehicle may be any one of a power battery state of charge signal, an output state signal of a dc converter/generator, an output power signal of the dc converter/generator, a collision signal, an electric power signal, a temperature signal of the dc converter/generator, a thermal runaway signal of the power battery, a power mode signal, or a combination of any several, and may further include other signals for energy management, for example, an external temperature signal, a fuel exhaustion signal of the vehicle, a tire failure signal of the vehicle, other failure signals of the vehicle, and the like, which are not limited herein. It is understood that the signal is related to the dc converter for a pure electric vehicle and the signal is related to the generator for an oil vehicle.
S102, identifying the current energy scene of the vehicle based on the current state signal of the vehicle.
After the current state signal of the vehicle is obtained, the vehicle-mounted terminal identifies the current energy scene of the vehicle according to the current state signal of the vehicle. For example, the energy scene in which the vehicle is currently located may be determined according to the correspondence between the status signal and the energy scene. In some embodiments, the identification may also be performed by a pre-trained machine learning model, the current state signal of the vehicle is input into the pre-trained machine learning model, and the energy scene in which the vehicle is currently located is identified by the pre-trained machine learning model. The present disclosure may also be identified by other means, not specifically limited herein.
In some embodiments, the identifying the energy scene in which the vehicle is currently located based on the current state signal of the vehicle includes identifying the energy scene in which the vehicle is currently located based on the current state signal of the vehicle in combination with a correspondence of the state signal and the energy scene.
Optionally, the corresponding relation between the state signals and the energy scenes is built by combining one or more state signals to obtain a plurality of state signal combinations, defining each state signal combination in the plurality of state signal combinations as an energy scene, and building the corresponding relation between the state signals and the energy scenes.
For example, a combination of a power battery state of charge signal in the power state signal being zero, an output state signal of the dc converter/generator in the vehicle running state signal being no output, and a power mode signal in the power state signal being a target mode is defined as a first energy scenario, which may represent a "power battery charge depletion waiting rescue" scenario.

S103, determining an energy management strategy corresponding to the energy scene where the vehicle is currently located.
After the current energy scene of the vehicle is identified, the vehicle-mounted terminal determines an energy management strategy corresponding to the current energy scene of the vehicle.

In some embodiments, the energy management strategy determines which electric appliances or functional modules are turned off in the energy scene to realize energy saving, and part of functions are turned off on the premise of keeping basic function requirements, so that normal use of key functions and normal storage battery states are ensured. For example, in a power battery depleted waiting rescue scenario, the corresponding energy management strategy is to turn off seat heating a single time, disable autopilot functionality, disable secondary drive entertainment screens, disable exterior trim lights, and the like. Because the life safety of the user is considered when waiting for rescue in extremely cold environments, an opening inlet is reserved for seat heating, the user can open a seat heating function in the scene, but the automatic driving function is disabled in the scene without requirement and high power consumption, the opening inlet of the automatic driving function is closed, and the user cannot open the automatic driving function in the scene. Similarly, the auxiliary driving entertainment screen is disabled, the opening entrance of the auxiliary driving entertainment screen is closed, the auxiliary driving entertainment screen cannot be opened by a user in the scene, the external decorative light is disabled, the opening entrance of the external decorative light is closed, the external decorative light cannot be opened by the user in the scene, energy is better saved through an energy management strategy, and normal use of key functions and normal storage battery states are ensured.
In some embodiments, before the energy management of the vehicle based on the energy management policy, the method further includes performing modular processing on a control function of a functional device to be controlled in the energy management policy to obtain a functional module to be controlled.
Optionally, the control function of the functional device to be controlled in the energy management policy is modularized in advance to obtain a functional module to be controlled, for example, the control function may be a closing function, and the function module can be controlled to enter a closing state by calling a corresponding "function closing" module. Each functional module may include an integration of control functions for at least one functional device. After the new energy scene is added, the function module can be directly called to control the device, the control device is prevented from being called for multiple times, the subsequent function expansion is facilitated, the new energy scene is added, the subsequent development workload is small, and the implementation is easy through OTA.

Specifically, the implementation process and principle of S303 and S103 are identical, and will not be described herein.
S304, determining a functional module to be controlled corresponding to the energy management strategy.
After determining an energy management strategy corresponding to an energy scene where the vehicle is currently located, the vehicle-mounted terminal determines a functional module to be controlled corresponding to the energy management strategy. The function module is a module having a control function for a certain function of the vehicle (for example, an autopilot function, a seat heating function, etc.) or for a certain device of the vehicle (for example, an air conditioner, an exterior lamp, an entertainment screen, etc.). For example, in a power battery exhaustion waiting rescue scenario, the corresponding energy management strategy is to turn off seat heating once, disable an autopilot function, disable a secondary driving entertainment screen, disable external decorative lights and the like, and it is determined that the functional modules to be controlled corresponding to the energy management strategy include a seat heating functional module, an autopilot functional module, a secondary driving entertainment screen functional module, an external decorative light functional module and the like.
In some embodiments, the control functions of the functional devices to be controlled in the energy management strategy are modularly processed in advance, and each functional module can include integration of at least one functional device control function. After the new energy scene is added, the function module can be directly called to control the device, the control device is prevented from being called for multiple times, the subsequent function expansion is facilitated, the new energy scene is added, the subsequent development workload is small, and the implementation is easy through OTA.

The target state may be a single shut down of the functional module, disabling of the functional module, reducing the power of the functional module, e.g., reducing the power of a wireless charge.

S307, judging whether the current state signal of the vehicle meets the exit condition of the energy scene where the vehicle is currently located.
Further, the vehicle-mounted terminal judges whether the current state signal of the vehicle meets the exit condition of the energy scene where the vehicle is currently located. For example, 1) a first energy scenario may represent a "power battery exhaustion waiting rescue" scenario, where the first energy scenario exits under the condition that the power value of the power battery state-of-charge signal is greater than a preset power threshold, or the output state signal of the DC converter/generator is output, 2) a second energy scenario may represent a "collision waiting rescue" scenario, where the second energy scenario exits under the condition that the collision signal is a user that has released the collision and the output state signal of the DC converter/generator is output, 3) a third energy scenario may represent a "power usage overload" scenario, where the third energy scenario exits under the condition that the output power value in the output power signal of the DC converter/generator is less than the preset power value threshold for a preset time, 4) a fourth energy scenario may represent a "thermal runaway waiting rescue" scenario, where the fourth energy scenario exits under the thermal runaway signal is a user that has released the thermal runaway.

In some embodiments, if the user changes the target state of the functional module to the first state in the energy scene, and exits the energy scene, the functional module is not restored to the initial state of the functional module, and the functional module is kept to the first state.
According to the method and the device, the current state signal of the vehicle is obtained, the current energy scene of the vehicle is identified based on the current state signal of the vehicle, and the energy management strategy corresponding to the current energy scene of the vehicle is determined.

In the RAM 603, various programs and data required for the operation of the electronic apparatus 600 are also stored. The processing device 601, the ROM 602, and the RAM 603 are connected to each other through a bus 604. An input/output (I/O) interface 605 is also connected to bus 604.
In general, devices may be connected to I/O interface 605 including input devices 606, including for example, touch screens, touch pads, keyboards, mice, cameras, microphones, accelerometers, gyroscopes, etc., output devices 607, including for example, liquid Crystal Displays (LCDs), speakers, vibrators, etc., storage devices 608, including for example, magnetic tape, hard disk, etc., and communication devices 609. The communication means 609 may allow the electronic device 600 to communicate with other devices wirelessly or by wire to exchange data. While fig. 5 shows an electronic device 600 having various means, it is to be understood that not all of the illustrated means are required to be implemented or provided. More or fewer devices may be implemented or provided instead.
In particular, according to embodiments of the present disclosure, the processes described above with reference to flowcharts may be implemented as computer software programs. For example, embodiments of the present disclosure include a computer program product comprising a computer program embodied on a non-transitory computer readable medium, the computer program comprising program code for performing the method shown in the flowcharts, thereby implementing the energy management method as described above. In such an embodiment, the computer program may be downloaded and installed from a network via communication means 609, or from storage means 608, or from ROM 602. The above-described functions defined in the methods of the embodiments of the present disclosure are performed when the computer program is executed by the processing device 601.
It should be noted that the computer readable medium described in the present disclosure may be a computer readable signal medium or a computer readable storage medium, or any combination of the two. The computer readable storage medium can be, for example, but not limited to, an electronic, magnetic, optical, electromagnetic, infrared, or semiconductor system, apparatus, or device, or a combination of any of the foregoing. More specific examples of a computer-readable storage medium may include, but are not limited to, an electrical connection having one or more wires, a portable computer diskette, a hard disk, a Random Access Memory (RAM), a read-only memory (ROM), an erasable programmable read-only memory (EPROM or flash memory), an optical fiber, a portable compact disc read-only memory (CD-ROM), an optical storage device, a magnetic storage device, or any suitable combination of the foregoing. In the context of this disclosure, a computer-readable storage medium may be any tangible medium that can contain, or store a program for use by or in connection with an instruction execution system, apparatus, or device. In the present disclosure, however, the computer-readable signal medium may include a data signal propagated in baseband or as part of a carrier wave, with the computer-readable program code embodied therein. Such a propagated data signal may take any of a variety of forms, including, but not limited to, electro-magnetic, optical, or any suitable combination of the foregoing. A computer readable signal medium may also be any computer readable medium that is not a computer readable storage medium and that can communicate, propagate, or transport a program for use by or in connection with an instruction execution system, apparatus, or device. Program code embodied on a computer readable medium may be transmitted using any appropriate medium, including but not limited to electrical wiring, fiber optic cable, RF (radio frequency), and the like, or any suitable combination of the foregoing.
In addition, the disclosed embodiments also provide a vehicle comprising a memory, a processor, and a computer program, wherein the computer program is stored in the memory and configured to be executed by the processor to implement the energy management method as described above.
In some embodiments, the clients, servers may communicate using any currently known or future developed network protocol, such as HTTP (HyperText Transfer Protocol ), and may be interconnected with any form or medium of digital data communication (e.g., a communication network). Examples of communication networks include a local area network ("LAN"), a wide area network ("WAN"), the internet (e.g., the internet), and peer-to-peer networks (e.g., ad hoc peer-to-peer networks), as well as any currently known or future developed networks.
The computer readable medium may be included in the electronic device or may exist alone without being incorporated into the electronic device.
The computer readable medium carries one or more programs which, when executed by the electronic device, cause the electronic device to:
acquiring a current state signal of a vehicle;
based on the current state signal of the vehicle, identifying an energy scene in which the vehicle is currently located;
Determining an energy management strategy corresponding to an energy scene where the vehicle is currently located;
Energy of the vehicle is managed based on the energy management strategy.
Alternatively, the electronic device may perform other steps described in the above embodiments when the above one or more programs are executed by the electronic device.
Computer program code for carrying out operations of the present disclosure may be written in one or more programming languages, including, but not limited to, an object oriented programming language such as Java, smalltalk, C ++ and conventional procedural programming languages, such as the "C" programming language or similar programming languages. The program code may execute entirely on the user's computer, partly on the user's computer, as a stand-alone software package, partly on the user's computer and partly on a remote computer or entirely on the remote computer or server. In the case of a remote computer, the remote computer may be connected to the user's computer through any kind of network, including a Local Area Network (LAN) or a Wide Area Network (WAN), or may be connected to an external computer (for example, through the Internet using an Internet service provider).
