In the related art, with the popularization of new energy automobiles, plug-in hybrid electric vehicles (Plug ≡ in hybrid electric vehicle, PHEV automobiles) are currently more common new energy automobiles. For PHEV cars, the current vehicle control strategy is: and preferentially using the electric energy until the electric energy is used for continuous voyage (namely EV continuous voyage) and then starting the engine to enter a hybrid mode. However, when the vehicle control strategy is adopted, the battery is completely driven at a high speed under a high-power working condition, the service life of the battery is influenced due to frequent high-power discharge, and the comprehensive endurance mileage of the whole vehicle cannot be optimized. And when the electric quantity of the power battery is sufficient and the electric quantity is insufficient, the power performance difference of the whole vehicle is obvious, and the power performance difference is also a point frequently complained by users.
The hybrid power system is provided with a plurality of power systems, the structure of the hybrid power system is complex, and the energy flows among different power devices can be combined with each other to form a plurality of working modes. Research shows that under the multi-working mode of the hybrid power system, the optimization of energy distribution among various power devices and the research on the power performance, economy and drivability of the automobile become hot spots and difficulties in the research of the current hybrid power driving system. The simple and reasonable control strategy is adopted to effectively reflect the driving intention of the driver on different working conditions of the automobile so as to adopt a reasonable working mode, so that the engine can be at an optimal working condition point, the fuel economy and the emission of the automobile are improved, and the service life of a power system (such as a battery pack) is prolonged.
In general, the performance of automobiles is a balance of dynamic and economic performance that combines the needs of most consumers. The performance of an automobile is difficult to meet the needs of all drivers with different sexes, different ages, and different driving styles. Such as: for some young male drivers, the power is pursued relatively, the power is strong, the acceleration is fast, the overtaking can be completed quickly, and the economy is not particularly seen; for some female consumers, comfort, stability, economy, etc., may be sought after with less obvious need for motivation. Clearly, a single style has not been able to meet the needs of different types of consumers.
To solve this problem, more and more automobile companies push driving operation mode setting buttons, and the driver can manually select various operation modes such as pure electric (EV, electric Vehicles), hybrid electric (HEV, hybrid Electric Vehicles), and the like. Different types of drivers can select driving modes according to their own needs.
However, although there are many companies that are currently developing hybrid vehicle models, most of the companies have not formulated different strategies for the operation modes of the hybrid vehicle, and still simply adopt: the energy management strategy is that the pure electric mode is simply adopted when electricity is available, and the hybrid electric mode is adopted when no electricity is available.
Therefore, the energy management strategy provided under the related technical scheme is single, the energy management control is not flexible enough, and different scene requirements of users cannot be met.
Therefore, the embodiment of the application firstly provides the energy management control method of the vehicle, by using the method, the defects can be overcome, and a plurality of energy modes are set from different scenes of users so as to meet different requirements of the users, so that user experience is improved, and user satisfaction is increased.

The target energy management operation mode may be a target energy management operation mode arbitrarily selected by a user from among a plurality of selectable energy management operation modes including a pure electric mode, a forced pure electric mode, a smart electric hybrid mode, and a power conservation priority mode.
The vehicle may be provided with one or more settings for the energy management mode of operation for the user. The energy management mode of operation provided by the vehicle to the user may include any of a number of settings including: the method comprises the steps of setting through physical keys, setting through a human-computer interaction interface of the vehicle-mounted terminal, setting through voice interaction with the vehicle-mounted terminal and setting through a mobile terminal capable of communicating with the vehicle-mounted terminal.

Referring to fig. 2, the system architecture includes a VCU (Vehicle Control Unit, a whole vehicle controller), an ACU (Audio Control Unit, a host and its controller), and a GW (Gateway), where the ACU is a controller in a vehicle-mounted intelligent multimedia host (AVNT), and the vehicle-mounted intelligent multimedia host (AVNT) provides a plurality of online function services for a user, such as a series of functions of voice, online music, online radio, online navigation, and application store, and communicates with other nodes of the whole vehicle through a CAN bus, ethernet, and the like.
Fig. 3 is a schematic diagram of an architecture of a meter information display host and an audio entertainment host, according to an example embodiment. Referring to fig. 3, the vehicle includes an audio entertainment host, that is, the foregoing vehicle-mounted intelligent multimedia host or vehicle-mounted terminal, where the software and hardware architecture of the host includes an ecological application, an operating system, and a hardware platform, specifically, the hardware platform may include a touch screen, and a user may interact with the vehicle-mounted intelligent multimedia host through the touch screen, that is, a man-machine interaction interface may be displayed in the touch screen, and the user may set an energy management operation mode through the man-machine interaction interface.
Next, how to set the target energy management operation mode through the man-machine interaction interface of the vehicle-mounted terminal is described.
Specifically, the man-machine interaction interface of the vehicle-mounted terminal can display buttons or soft keys corresponding to the energy management operation modes, and a user can select and set the corresponding energy management operation modes by triggering a certain button or soft key in the man-machine interaction interface.
Fig. 5 is a schematic diagram of a setup interface for a pure priority mode, according to an example embodiment. Referring to fig. 5, the man-machine interface of the vehicle-mounted terminal includes soft keys corresponding to a pure electric priority mode, a smart hybrid mode and a power-saving priority mode, and when the user triggers the soft key corresponding to the pure electric priority mode, the soft key is highlighted and simultaneously displays the setting interface of the pure electric priority mode shown in fig. 5, which includes description information related to the pure electric priority mode.
In one embodiment of the application, the target setting mode is set through a human-computer interaction interface of the vehicle-mounted terminal; acquiring a target energy management operation mode set for a vehicle by a user through a target setting mode in at least one setting mode of the energy management operation modes, including: and acquiring a forced pure electric mode set by a user for the vehicle through a setting interface of the pure electric priority mode in the man-machine interaction interface of the vehicle-mounted terminal.
With continued reference to fig. 5, the setting interface of the pure electric preference mode further includes a slide button corresponding to the forced pure electric mode, and the user can enter the forced pure electric mode by opening the slide button.
The lower limit of the available SOC (State of Charge) of the forced pure electric mode is lower than that of the pure electric priority mode, and a longer pure electric range can be supported.
The forced pure electric mode is equivalent to the pure electric priority mode of the enhanced version, so that the user can normally set the forced pure electric mode, and meanwhile, the number of soft keys displayed in the man-machine interaction interface is reduced, so that the interface is more concise, and the user experience is improved.
Of course, in other embodiments of the present application, the user may set the forced pure electric mode by other means such as a key.
In one embodiment of the present application, after acquiring the target energy management operation mode set by the user for the vehicle, the energy management control method of the vehicle further includes: displaying information related to the target energy management operating mode on at least one of the following display interfaces: human-computer interaction interface of the vehicle-mounted terminal and instrument interface of the vehicle.
Part or all of the information of the target energy management operation mode can be displayed in a human-computer interaction interface of the vehicle-mounted terminal and/or an instrument interface of the vehicle. For example, all information of the target energy management operation mode may be displayed in the instrument interface of the vehicle, for example, the target electric quantity in the electricity retention priority mode may be displayed, and of course, only information indicating the target energy management operation mode, such as an icon, a name, and the like of the target energy management operation mode may be displayed in the instrument interface of the vehicle, so that the display of the information in the instrument interface of the vehicle is more concise.
With continued reference to fig. 2, the system architecture further includes an ICM (Instrument Control Module, meter) capable of communicating with the GW, and the GW, VCU, and ACU and ICM may communicate over a bus. When the user sets the energy management operation mode through the man-machine interaction interface of the vehicle-mounted terminal, the ACU sends a corresponding energy mode setting signal to the GW.
After receiving the energy mode setting signals, the GW forwards the energy mode setting signals to the VCU, the VCU generates energy mode display signals after receiving the signals and sends the energy mode display signals to the GW, on one hand, the GW sends the energy mode display signals to the ACU and displays the energy modes through a man-machine interaction interface of the vehicle-mounted terminal, and on the other hand, the GW also sends the energy mode display signals to the ICM, and the ICM displays and lights the corresponding energy modes. The energy mode display signal sent by the GW to the ICM may be a vcu_operatingmode signal, where vcu_operatingmode=4 represents a forced pure electric mode, and after the meter receives the signal, the meter may display "pure electric priority" of a blue font.
In one embodiment of the present application, the target setting mode is set by a physical key; acquiring a target energy management operation mode set for a vehicle by a user through a target setting mode in at least one setting mode of the energy management operation modes, including: and acquiring a target energy management operation mode set for the vehicle by a user through triggering a specified physical key, wherein the triggering of the specified physical key can switch among a plurality of selectable energy management operation modes.
With continued reference to fig. 2, the system architecture further includes an energy mode switch, which is electrically connected to the VCU by a hard wire, the energy mode switch, i.e., designates a physical key, which may also be referred to as a hard key, which may send a target energy management operation mode to the VCU by directly sending a hard wire signal to the VCU, the VCU performing according to the relevant energy mode, and feeding back the result set by the user to a host controller (ACU) and a meter (ICM) through a Gateway (GW), and displaying them on the host (AVNT) and the meter, respectively.
The logic for realizing the energy mode switching based on the physical key is specifically as follows: when the current execution mode is the electricity-saving priority mode, the physical key is pressed for a short time to enter the pure electric priority mode, and the physical key is pressed for a long time to enter the forced pure electric mode; when the current execution mode is a pure electric priority mode or an intelligent electric hybrid mode, the short-press physical key can be switched between the two modes, and the long-press physical key enters a forced pure electric mode; when the current execution mode is the forced pure electric mode, the physical key is pressed for a short time to enter the pure electric priority mode, the long-time press is not responded, and the forced pure electric mode is continuously executed.
The key trigger logic may be: starting timing from the change of the key-press level, and ending the timing of the change of the key-release level again. When the key is pressed, the length is larger than 0.2s and smaller than 2s, the short press is identified, and when the key is pressed, the length is larger than or equal to 2s, the long press is identified. The VCU will execute the switching of the energy mode after the key release timing is completed.
Of course, the time periods for judging the short press and the long press may be set to other time periods, which are not limited herein.
By using one designated physical key, switching between all energy management modes of operation can be made, making the user feel more concise. Of course, in other embodiments of the present application, a plurality of physical keys may also be provided to the user, each for triggering a respective energy management mode of operation.
When the energy mode is switched into pure electric priority and intelligent electric hybrid power through the physical keys, corresponding soft keys can be synchronously highlighted in a human-computer interaction interface of the vehicle-mounted terminal; when the forced pure electric mode is switched to by the physical key, a switch of the forced pure electric mode in a man-machine interaction interface of the vehicle-mounted terminal can be started in a linkage way.
The following describes how the setting of the energy management operation mode is performed by performing the setting through voice interaction with the in-vehicle terminal.
After waking up a host controller (ACU), a user can set an energy management operation mode through voice. The AVNT host machine (the controller of the AVNT host machine is ACU) is used for identifying an energy management operation mode wanted by a user, a result set by the user is fed back to the whole vehicle controller VCU and the instrument through the Gateway (GW), the result is respectively displayed on the host machine (AVNT) and the instrument, and finally the VCU performs energy management control on the vehicle according to the relevant energy mode.
Specifically, if a user wants to open a certain energy management operation mode, the user needs to send out a voice for indicating to open the energy management operation mode, after receiving the voice, the AVNT host computer recognizes text information corresponding to the voice, and then matches the text information with text information preset in the AVNT host computer and respectively corresponding to the energy management operation modes; if the identified text information is matched with the text information corresponding to opening a certain energy management operation mode, the set target energy management operation mode is determined to be the energy management operation mode.
For example, the "open pure electric priority mode", "start pure electric priority mode", "open pure electric driving mode", "start pure electric driving mode", and the like may be set for the open pure electric priority mode, and once it is detected that the identified text information matches one of the text information, the set target energy management operation mode is determined to be the pure electric priority mode, at this time, the AVNT host may reply with voice "good for your open pure electric priority mode", and if the current state of the vehicle does not support the open pure electric priority mode, the AVNT host may reply with voice "your loving vehicle temporarily cannot open pure electric priority mode".
For forced pure electric mode, smart electric hybrid mode, and power save priority mode, the energy management mode of operation may also be turned on based on speech recognition in a manner similar to the pure electric priority mode.
In order to ensure that the function of setting the energy management operation mode by voice is triggered by mistake, the authority of the function can be set to be limited to the main driving; if the voice sound source comes from other positions in the vehicle or outside the vehicle, the AVNT host can reply with voice that the main driving control is only supported temporarily, and the main driving is requested to give an instruction.

Fig. 8 is a flow diagram illustrating pure control logic according to an example embodiment. Referring to fig. 8, after the process starts, if the user selects the pure electric priority mode, it is determined whether the SOC is greater than 20%, and if so, it is further determined whether the wheel end power demand is greater than the pure electric power. The wheel end required power is obtained according to the opening degree of the accelerator pedal, and the wheel end required power and the opening degree of the accelerator pedal have a one-to-one correspondence, so that the wheel end required power is equivalent to the opening degree of the accelerator pedal, the pure electric power is allowable discharging power of the power battery, and the pure electric power is equivalent to a preset opening threshold value.
In one embodiment of the present application, after obtaining the forced pure electric mode set by the user for the vehicle, the method further comprises: if the residual electric quantity of the power battery of the vehicle is above a second preset electric quantity threshold value, judging whether the allowable discharge power of the power battery is smaller than the preset power threshold value and the condition that the wheel end required power of the vehicle is larger than the allowable discharge power of the power battery is met, wherein the preset power threshold value is larger than the preset wheel end required power threshold value, and the second preset electric quantity threshold value is larger than the first preset electric quantity threshold value; if the allowable discharge power of the power battery is smaller than the preset power threshold and the condition that the wheel end required power of the vehicle is larger than the allowable discharge power of the power battery is met, starting an engine of the vehicle and driving the vehicle to run at least through the engine; if the allowable discharge power of the power battery is smaller than the preset power threshold and the condition that the wheel end required power of the vehicle is larger than the allowable discharge power of the power battery is not satisfied, the vehicle is driven to run by the power battery.

The second preset power threshold corresponding to the forced pure electric mode may be the same as or different from the first preset power threshold corresponding to the pure electric priority mode.
The second preset power threshold corresponding to the forced pure electric mode may be 20%, or may be other values such as 21%, 22%.

When the actual SOC is more than or equal to 20%, when the forced pure electric shutdown requirement conflicts with the self startup requirement of an engine management system (Engine Management System, EMS), the VCU can shield the shutdown prohibition requirement sent by the functions of heating, diagnosis and the like of the EMS catalyst.
The preset power threshold may be 60kw or other values; the preset wheel end required power threshold value can be 35kw or other values.
Referring to fig. 8, if the user selects the forced pure electric mode, it is determined whether the SOC is greater than 20%, if so, it is further determined whether the pure electric power is less than 60kw and the condition that the power required by the wheel end is greater than the pure electric power is satisfied, where the pure electric power is the allowable discharge power of the power battery, and if so, the engine is allowed to be started, i.e. hybrid running is performed; if not, the vehicle is driven by the power battery only and the pure electric vehicle is driven only. When the hybrid running is carried out, the engine and the power battery can drive the vehicle to run simultaneously, or the engine can drive the vehicle to run only, and in the process, the engine can charge the power battery.

The preset opening threshold may be set to various values, for example, 80%, or other values such as 81%, 82%. The preset opening thresholds corresponding to the pure electric priority mode and the forced pure electric mode may be the same or different.
With continued reference to fig. 8, if the SOC is greater than 20%, if the wheel end power demand is greater than the full power, that is, the accelerator pedal opening of the vehicle reaches the preset opening threshold, the engine of the vehicle is started to perform hybrid driving.
