Description

Technical Field

[0001] This invention belongs to the technical field of new energy vehicles (including plug-in hybrids, range-extended hybrids, etc.), and specifically relates to a control method, system, vehicle, and storage medium for a new energy vehicle as a mobile power station. Background Technology

[0002] With the development of electric and intelligent vehicles, new energy vehicles are becoming increasingly popular. Pure electric, plug-in hybrid, and range-extended hybrid vehicles all have a large-capacity power battery, making it possible for new energy vehicles to function as mobile power stations. New energy vehicles typically utilize onboard devices to convert 220V AC power from the grid into high-voltage DC power within the power battery, and vice versa. By using onboard discharge devices to convert the high-voltage DC power from the power battery into 220V AC power, new energy vehicles can act as mobile power stations, supplying external electrical loads and meeting users' needs for 220V AC power, thus significantly improving the user experience.

[0003] For new energy vehicles as mobile power stations, there are currently two control strategies: (1) When the user uses this function, the engine cannot be started to charge the power battery. When the power battery is not charged enough, the control strategy directly shuts down the discharge function of the on-board discharge assembly. (2) When the user uses this function, the vehicle automatically controls the engine to start when the power battery is not charged enough, so that the engine can charge the power battery at idle speed. However, method (1) cannot meet the user's demand for 220V AC power when the power battery is not charged enough but the fuel is sufficient. Method (2) can meet the user's demand for 220V by automatically starting the engine when the power battery is not charged enough but the fuel is sufficient. However, if the vehicle starts the engine in a closed space, it may not be conducive to the exhaust of exhaust gas. The sudden start of the engine may also make the user feel very abrupt. This strategy may cause the power battery to drop to a very low level after the user uses this function. When the user enters the city driving condition, he / she will not be able to enter the pure electric driving mode, which will increase fuel consumption. It may also cause the user to be limited in power when entering the high-speed driving condition. This will affect the user experience. If the threshold for automatic engine start is increased, the engine may be easily triggered when the battery is high during the discharge process, which is detrimental to user experience and economy.

[0004] For example, patent document CN214164723U discloses a mobile power station based on a hybrid electric vehicle, which mentions that when the power battery charge is less than a second threshold, the vehicle automatically starts the engine, controls the engine to output energy, and charges the power battery through the motor. The control strategy mentioned in this mobile power station based on a hybrid electric vehicle still has the potential impact on user experience, fuel consumption, power performance, and health that may exist in method (2).

[0005] Therefore, it is necessary to develop a control method, system, vehicle, and storage medium for a new energy vehicle as a mobile power station. Summary of the Invention

[0006] The purpose of this invention is to provide a control method, system, vehicle, and storage medium for a new energy vehicle as a mobile power station, which can maximize the utilization of onboard electric and fuel energy, control engine operation entirely based on user wishes, and ensure the safety of the power battery charge.

[0007] In a first aspect, the present invention provides a control method for a new energy vehicle as a mobile power station, which divides the powertrain control state of the powertrain controller into a Stop state, a Crank state, a Running state, and a DCAC state. The Stop state indicates that the vehicle is stopped; the Crank state indicates that the vehicle is started; the Running state indicates that the motor or engine is running; and the DCAC state indicates that the discharge gun and the new energy vehicle are connected. In the DCAC state, the engine can still be in a running or stopped state. The method includes the following steps:

[0008] In Stop or Running state, in response to the detection that the discharge gun is connected to the new energy vehicle, the powertrain controller enters DCAC state to supply power to the electrical load outside the vehicle.

[0009] In DCAC mode, in response to the detection that the power battery charge is lower than the first preset charge threshold, the powertrain controller issues a prompt signal to start the engine, and the new energy vehicle performs an engine start prompt operation based on the prompt signal.

[0010] In DCAC mode, in response to detecting a user's active vehicle start operation, a start control signal is issued, and the powertrain controller issues an engine start request based on the start control signal and performs the engine start action.

[0011] In DCAC mode, in response to detecting that an engine start prompt operation has been performed but the engine has not been started, and the power battery charge is greater than a second preset charge threshold, the powertrain controller allows continued discharge, and when it detects that the power battery charge is less than or equal to the second preset charge threshold, the powertrain controller disables the discharge function; wherein, the second preset charge threshold is less than the first preset charge threshold.

[0012] Optionally, in DCAC state, in response to the detection that the discharge gun and the new energy vehicle have been disconnected, the powertrain controller will switch from DCAC state to Stop state. If the engine is running at this time, the engine will be forcibly shut down.

[0013] Optionally, in response to detecting that the engine is in a stopped state, the powertrain controller feeds back the powertrain state as a Stop state to the body controller; in response to detecting that the engine is running or starting, the powertrain controller feeds back the powertrain state as a Running state to the body controller.

[0014] Optionally, in DCAC mode, in response to detecting a user's active start-up of the vehicle, the body controller sends a start control signal to the powertrain controller.

[0015] Optionally, after the body controller sends a start control signal to the powertrain controller, if the powertrain control status received from the powertrain controller within a preset time is either Crank or Running, or if the preset time is exceeded, the body controller issues a stop start request.

[0016] Optionally, the engine start prompt operation includes one or more combinations of instrument display, APP display, hazard light flashing, and horn blasting, providing multiple reminder methods.

[0017] Optionally, after the engine starts, control is performed based on the target SOC of the vehicle idling charge, and the engine operating load will prioritize the needs of air conditioning, external discharge, and the target SOC.

[0018] Optionally, after the powertrain controller disables the discharge function, the engine is configured to still be able to start normally. When it is necessary to supply power to electrical loads outside the vehicle, the engine can be started normally to charge the power battery, thereby supplying power to the electrical loads.

[0019] Optionally, when the power battery charge is detected to be less than or equal to a third preset charge threshold, the power supply is cut off, wherein the third preset charge threshold is the physical limit of the power battery charge, and the third preset charge threshold is less than a second preset charge threshold, that is, protection logic is set for the lower limit of the power battery charge.

[0020] Secondly, the control system for a new energy vehicle as a mobile power station according to the present invention includes a memory and a controller. The memory stores a computer-readable program, which, when invoked by the controller, can execute the steps of the control method for a new energy vehicle as a mobile power station as described in the present invention.

[0021] Thirdly, the vehicle described in this invention employs a control system as described in this invention, which uses a new energy vehicle as a mobile power station.

[0022] Fourthly, the present invention provides a storage medium storing a computer-readable program, which, when invoked by a controller, can execute the steps of the control method for a new energy vehicle as a mobile power station as described in the present invention.

[0023] The present invention has the following advantages:

[0024] (1) After the discharge gun is connected to the new energy vehicle, the powertrain controller (PCU) internally controls the powertrain status to enter DCAC state (i.e., discharge state), and the engine's operation and shutdown are entirely controlled according to the user's wishes. When the powertrain status controlled by the PCU is DCAC state, the vehicle can be in a state where the engine is running or stopped. If the engine is not running, the PCU feeds back the powertrain status as Stop state to the body controller. If the engine is running or starting, the PCU feeds back the powertrain status as Running state to the body controller. When the powertrain status controlled by the PCU is DCAC state, if the user actively performs a normal start operation, the start button will input a high-level voltage to the body controller via a hard wire, and the brake pedal will also input a high-level voltage to the body controller via a hard wire. The body controller will send an engine start request to the PCU based on the input voltage and other conditions. When the powertrain status controlled by the PCU is DCAC state, after receiving the engine start request from the body controller, the PCU will forcibly start the engine, thereby ensuring that the engine starts and runs according to the user's wishes. After the engine starts, it will be controlled according to the target SOC (energy charge) of the vehicle idling. At the same time, the engine operating load will prioritize the needs of air conditioning, external discharge, and the target SOC.

[0025] (2) When the power battery's charge reaches its limit (i.e., when the power battery's charge is below the first preset charge threshold), and the user has not actively started the engine beforehand, the PCU will send a start-up signal to the instrument panel and mobile terminal. The instrument panel will provide a prominent reminder through one or more combined methods, such as displaying information, illuminating the hazard warning lights, or sounding the horn, to alert the user that the power battery is low and the engine needs to be started. Alternatively, a prominent reminder can be provided via the mobile terminal's app to alert the user that the power battery is low and the engine needs to be started. This avoids allowing the power battery to continue supplying power to external electrical loads for an extended period, which could cause the power battery charge to drop further and eventually discharge and shut down. If it is necessary to continue supplying power to external electrical loads, the engine must be started normally.

[0026] (3) If the power battery is used up to its limit and the user does not actively start the engine after a significant reminder, and the power battery level drops further to a lower threshold (i.e., the power battery level is less than the second preset power threshold), the PCU will shut down the discharge motor. After the discharge motor is shut down, if the user still wants to continue discharging the external electrical loads after noticing this, they can still start the engine through normal starting operations. At this time, the engine can still replenish the power battery after it runs, and can still restore the power supply to the external electrical loads.

[0027] In summary, this invention can maximize the use of onboard electric and fuel energy, control engine operation entirely based on user wishes, ensure the safety of the power battery, avoid the impact of sudden engine start on user experience, and avoid the potential risk of engine start-up due to external misoperation in a confined space. Attached Figure Description

[0028] To more clearly illustrate the technical solutions of the embodiments of the present invention, the accompanying drawings used in the embodiments will be briefly introduced below. It should be understood that the following drawings only show some embodiments of the present invention and should not be regarded as a limitation on the scope. For those skilled in the art, other related drawings can be obtained based on these drawings without creative effort.

[0029] Figure 1 This is the energy flow path diagram in this embodiment;

[0030] Figure 2 This is the signal interaction path diagram in this embodiment;

[0031] Figure 3 This is the PCU powertrain state control diagram in this embodiment;

[0032] Figure 4 This is the internal control flowchart of the PCU in this embodiment;

[0033] Figure 5 This is the BCM startup control flowchart in this embodiment. Detailed Implementation

[0034] The present invention will now be described in detail with reference to the accompanying drawings.

[0035] like Figure 1The diagram shown illustrates the energy flow path in this embodiment, including an engine, generator, power battery, discharger, discharge socket, discharge gun, and electrical loads (referring to external electrical loads). The power battery's charge is output to the external electrical loads through the discharger, discharge socket, and charging gun, supplying power to them. This path converts the high-voltage direct current output from the power battery into alternating current. After the user actively starts the engine, the chemical energy of the fuel is converted into mechanical energy through engine combustion. The generator then converts the engine's mechanical energy into high-voltage direct current and charges the power battery.

[0036] like Figure 2 The diagram shown illustrates the signal interaction path in this embodiment. After the user performs a normal start operation, the voltage signals from the start button and brake pedal will trigger the body controller to issue an engine start request (i.e., a start request signal).

[0037] BCM_StartSignal = StartReq). When the power battery's charge reaches its limit (i.e., the power battery charge is less than a first preset charge threshold), the powertrain controller (PCU) will send an engine start signal (PCU_InfDis) to the instrument cluster and other controllers. The instrument cluster and other controllers will then use one or more methods, such as displaying the instrument cluster, flashing hazard lights, or sounding the horn, to remind the user to pay attention to the power battery's charge level. Alternatively, the engine start signal can be sent to an app installed on a mobile device for a prominent notification. The powertrain controller will also report the powertrain status (PCU_PwrTrainSts) to the body controller.

[0038] like Figure 3 As shown, in this embodiment, the powertrain control states are divided into: Stop state, Crank state, Running state, and DCAC state. Stop state indicates the vehicle is stopped, Crank state indicates the vehicle is started, Running state indicates the motor or engine is running, and DCAC state indicates the discharge gun and vehicle are connected. In Stop or Running state, once the discharge gun is detected to be connected to the discharge socket of the new energy vehicle, the powertrain controller will enter DCAC state. In DCAC state, the engine can still be running or stopped. In DCAC state, if the discharge gun is removed, the powertrain controller will switch from DCAC state to Stop state. If the engine is running at this time, the engine will be forcibly shut down.

[0039] In this embodiment, a control method for a new energy vehicle as a mobile power station includes the following steps:

[0040] In Stop or Running mode, upon detecting that a discharge gun is connected to the new energy vehicle, the powertrain controller enters DCAC mode to supply power to the external electrical load. In DCAC mode, upon detecting that the battery charge is below a first preset threshold, the powertrain controller sends an engine start signal. The new energy vehicle then uses this signal to initiate engine start (including one or more combinations of instrument panel display, app display, flashing hazard lights, and horn blast to clearly remind the user of low battery and to start the engine). In DCAC mode, upon detecting a user's active vehicle start operation, the body controller sends a start control signal. The powertrain controller then sends an engine start request based on this signal and initiates the engine start action. After the engine starts, control is performed based on the target SOC (State of Charge) for idling charging (the engine load will prioritize air conditioning needs, external discharge needs, and the target SOC). In DCAC mode, in response to a detected engine start prompt but no engine start, and if the battery charge is greater than a second preset charge threshold, the powertrain controller allows continued discharge. Upon detecting a battery charge less than or equal to the second preset charge threshold, the powertrain controller disables the discharge function. In other words, after clearly prompting the user, if the user does not trigger engine start, the powertrain controller will allow the battery to continue discharging for a certain period until the battery charge is less than or equal to the second preset charge threshold, at which point the powertrain controller disables the discharge function. The second preset charge threshold is less than the first preset charge threshold.

[0041] like Figure 3 As shown, in this embodiment, if the engine is in a stopped state, the powertrain controller feeds back the powertrain status as "Stop" to the body controller. If the engine is starting or running in DCAC state, the powertrain controller feeds back the powertrain operating status (PCU_PwrTrainSts) as "Running" to the body controller due to the needs of other control strategies. If the engine is running in DCAC state and the discharge gun is disconnected (i.e., in DCAC state, in response to detecting that the discharge gun and the new energy vehicle are disconnected), the powertrain controller will switch from DCAC state to Stop state.

[0042] In this embodiment, when the body controller receives a user's active vehicle start operation, such as pressing the start button (start button outputs a high level) or pressing the brake pedal (brake pedal outputs a high level), the body controller sends a start control signal BCM_StartSignal = StartReq to the powertrain controller. After the body controller sends the start control signal to the powertrain controller, if the powertrain control status fed back by the powertrain controller is Crank or Running (i.e., PCU_PwrTrainSts = Crank or Running fed back by the PCU) within a preset time, or if the preset time is exceeded, the body controller sends a stop start request, i.e., BCM_StartSignal = StopStartReq.

[0043] In this embodiment, after the discharge gun is connected to the discharge socket on the new energy vehicle, the powertrain will enter DCAC state. In this DCAC state, to ensure safety, the new energy vehicle must remain in a parked state, meaning it cannot move or drive.

[0044] In this embodiment, when the power battery charge is detected to be less than or equal to a third preset charge threshold, the power is cut off. The third preset charge threshold is the physical limit of the power battery charge. The third preset charge threshold is less than the second preset charge threshold, which means that protection logic is set for the lower limit of the power battery charge.

[0045] In this embodiment, if the user still wants to continue discharging the external electrical loads after the discharger is turned off, the engine can still be started through normal starting operation. At this time, the engine can still replenish the power battery and resume power supply to the external electrical loads.

[0046] This method can maximize the use of onboard electric and fuel energy, control engine operation entirely based on user wishes, ensure the safety of the power battery, avoid the impact of sudden engine start on user experience, and avoid the potential risk of engine start-up due to external misoperation in a confined space.

[0047] like Figure 4 As shown, in this embodiment, the control flow inside the PCU is as follows:

[0048] Step 1: Insert the discharge gun into the discharge socket of the new energy vehicle;

[0049] Step 2: The powertrain controller enters DCAC state, i.e., discharge state.

[0050] Step 3: Determine whether the body control system has issued an engine start request (i.e., BCM_StartSignal = 0x1);

[0051] Step 4: If there is a startup request, proceed to Step 5; otherwise, proceed to Step 9.

[0052] Step 5: Discharge the power battery to enable and force start the engine;

[0053] Step 6: Enable discharge and control the generator to generate electricity;

[0054] Step 7: Determine if the user has a shutdown request. If there is no shutdown request, proceed to Step 8; if there is a shutdown request, proceed to Step 9.

[0055] Step 8: Enable the power battery discharge and control the generator to generate electricity; then proceed to step 13;

[0056] Step 9: The power battery discharges, and the power battery charge continues to decrease;

[0057] Step 10: When the power battery charge drops to the first preset charge threshold, the PCU sends a prompt signal (PCU_InfDis). If the user does not start the device, proceed to step 11; if the user does start the device, proceed to step 3.

[0058] Step 11: The power battery continues to discharge, and the power battery charge continues to decrease;

[0059] Step 12: When the power battery's charge level drops to the second preset charge threshold, the PCU shuts down the discharge function.

[0060] Step 13: Disconnect the discharge gun;

[0061] Step 14: Exit the discharge state.

[0062] like Figure 5 As shown, in this embodiment, the start-up control process of the body controller is as follows:

[0063] S1. The body controller did not send a request to start the engine, i.e., the start control signal BCM_StartSignal = 0x0;

[0064] S2. Determine the voltage signal of the engine start button. If the start button outputs a low level, return to S1. If the start button outputs a high level, proceed to S3.

[0065] S3. The body controller sends an engine start request, i.e., the start control signal BCM_StartSignal = 0x1;

[0066] S4. Determine if the powertrain operating status is PCU_PwrTrainSts=Crank or Running, or if a timeout has occurred; if yes, proceed to S5; otherwise, return to S3.

[0067] S5. The body controller sends a start control signal BCM_StartSignal=0x2, which is to request a shutdown.

[0068] In this embodiment, a control system for a new energy vehicle as a mobile power station includes a memory and a controller. The memory stores a computer-readable program, which, when invoked by the controller, can execute the steps of the control method for a new energy vehicle as a mobile power station as described in this embodiment.

[0069] In this embodiment, a vehicle uses a control system for a mobile power station, as described in this embodiment, which is a new energy vehicle.

[0070] In this embodiment, a storage medium stores a computer-readable program, which, when invoked by a controller, can execute the steps of the control method for a new energy vehicle as a mobile power station as described in this embodiment.

[0071] In this embodiment, the names of controllers such as PCU, BCM, and instrument cluster are not specific, nor are their related control function divisions specific, and may vary. The main purpose is to illustrate how user startup requirements are translated into powertrain control states, and how these powertrain states relate to controls such as forced engine start.

[0072] In this embodiment, the representation of the user's initiation operation is not limited to the start button and brake pedal voltage signal mentioned in the text. It may also be represented by other methods such as voice. This mainly illustrates how the user's operation is converted, recognized, judged, and issued by the relevant control.

[0073] In this embodiment, the engine operation in DCAC state is described as returning to Stop immediately after the discharge gun is removed; this is merely an example to illustrate one control scenario. If this scenario returns to Running state and is combined with other control strategies, it also reflects the control concept described in this paper of starting the engine entirely based on user intention while the vehicle is discharging.

[0074] In this embodiment, if the engine is starting or running under DCAC conditions, the PCU_PwrTrainSts fed back to the BCM will still be "Running" due to the needs of other control strategies. This control method is only an example to illustrate one control situation. Other methods that embody the idea of ​​starting the engine entirely based on user wishes under vehicle discharge conditions all fall within the scope of the control strategies described in this invention.

[0075] In this embodiment, the name of the powertrain control state inside the PCU is not specific, but mainly used to illustrate the working state of the powertrain.

[0076] It should be noted that the storage medium shown in this embodiment can be a computer-readable signal medium or a computer-readable storage medium, or any combination thereof. A computer-readable storage medium can be, for example, an electrical, magnetic, optical, electromagnetic, infrared, or semiconductor system, apparatus, or device, or any combination thereof. 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 disk, a hard disk, random access memory (RAM), read-only memory (ROM), erasable programmable read-only memory (EPROM), flash memory, optical fiber, portable compact disc read-only memory (CD-ROM), optical storage devices, magnetic storage devices, or any suitable combination thereof. In this embodiment, the computer-readable signal medium may include a data signal propagated in baseband or as part of a carrier wave, carrying a computer-readable computer program. Such propagated data signals can take various forms, including but not limited to electromagnetic signals, optical signals, or any suitable combination thereof. Computer-readable signal media can also be any computer-readable medium other than computer-readable storage media, which can send, propagate, or transmit a program for use by or in connection with an instruction execution system, apparatus, or device. The computer program contained on the computer-readable medium can be transmitted using any suitable medium, including but not limited to wireless, wired, etc., or any suitable combination thereof.
