[0050] The processor 1100 is configured to receive a first instruction for entering a power conservation mode.

[0051] The processor 1100 is further configured to control the vehicle to enter a power conservation mode according to a running state of the vehicle in response to the first instruction;

[0052] Processor 1100 is also used to control the battery management system of the vehicle to disconnect the external power supply of the starting battery of the vehicle when the vehicle enters the power conservation mode.

[0053] The processor 1100 is further used to control the battery management system to set the discharge branch of the start-up battery to a disconnected state.

[0054] Processor 1100 is also used to control the vehicle to enter a power conservation mode when the vehicle is not in a driving state and if the vehicle's gear is in the parking gear for a preset time and the high voltage of the entire vehicle is turned off; when the vehicle is in a driving state, limit the vehicle's driving speed to a preset speed; and, after the vehicle stops driving, if the vehicle's gear is in the parking gear for a preset time and the high voltage of the entire vehicle is turned off, control the vehicle to enter a power conservation mode.

[0055] Processor 1100 is also used to control the vehicle to enter a power conservation mode when the power level of the vehicle's power battery is higher than or equal to a first preset power level and the high voltage of the entire vehicle is powered off; to prompt the user to charge when the power level of the vehicle's power battery is lower than the first preset power level; and, after charging, if the power level of the vehicle's power battery is higher than or equal to the first preset power level and the high voltage of the entire vehicle is powered off, to control the vehicle to enter a power conservation mode.

[0061] Despite Figure 1 Although multiple devices are shown for the electronic device 1000, the present disclosure may only involve some of the devices, for example, the electronic device 1000 only involves the memory 1200 and the processor 1100.

[0062] In the embodiment of the present disclosure, the memory 1200 of the electronic device 1000 is used to store instructions, and the instructions are used to control the processor 1100 to execute the vehicle control method provided by the embodiment of the present disclosure.

[0063] In the above description, the technician can design instructions according to the scheme disclosed in the present disclosure. How instructions control the processor to operate is well known in the art, so it will not be described in detail here.

[0064] The electronic device provided in the embodiment of the present disclosure can control the external power-off of the starting battery through the software system when the vehicle enters the power conservation mode. The user does not need to unplug the negative pole of the starting battery, which lowers the user's operation threshold and can reduce the power loss of the starting battery, thereby reducing the possibility of the starting battery running out of power due to long-term parking.

[0065] <Method Example>

[0066] The embodiment of the present disclosure provides a vehicle control method. Figure 1 The electronic device 1000 shown performs.

[0067] like Figure 2 As shown, the method includes the following S2100-S2300:

[0068] S2100: Receive a first instruction to enter a power conservation mode.

[0069] The first instruction in the embodiment of the present application can be a trigger operation of a button or switch set on an operation panel of the vehicle by a user, or a trigger operation of a touch screen set on the vehicle by a user, and the first instruction is generated after the vehicle stops. The present application does not limit the specific triggering method of the first instruction.

[0070] S2200: In response to the first instruction, control the vehicle to enter a power conservation mode according to the operating state of the vehicle.

[0071] In one embodiment, the vehicle is controlled to enter a power conservation mode according to the operating state of the vehicle, including: when the vehicle is not in a driving state, if the vehicle's gear is in the parking gear for a preset time and the high voltage of the entire vehicle is powered off, the vehicle is controlled to enter the power conservation mode; when the vehicle is in a driving state, the vehicle's driving speed is limited to a preset speed, and, after the vehicle stops driving, if the vehicle's gear is in the parking gear for a preset time and the high voltage of the entire vehicle is powered off, the vehicle is controlled to enter the power conservation mode.

[0072] Limiting the vehicle's speed to below the preset speed can avoid safety hazards caused by the vehicle's excessive speed, and is also convenient for timely control of the vehicle to stop and enter the power conservation mode; at the same time, the power consumption required to travel the same distance at a speed below the preset speed is smaller, which can reduce the power consumption of the vehicle's power battery, thereby ensuring that the power battery has sufficient power.

[0073] In one embodiment, controlling the vehicle to enter a power conservation mode according to the operating status of the vehicle may specifically include: controlling the vehicle to enter a power conservation mode when the power level of the vehicle's power battery is higher than or equal to a first preset power level and the entire vehicle is powered off at high voltage; prompting a user to charge when the power level of the vehicle's power battery is lower than a first preset power level, and, after charging, if the power level of the vehicle's power battery is higher than or equal to the first preset power level and the entire vehicle is powered off at high voltage, controlling the vehicle to enter a power conservation mode.

[0074] By prompting the user to charge the vehicle when the power battery of the vehicle is low on power, it can be ensured that the power battery has sufficient power when the vehicle enters the power conservation mode; since the power battery of the vehicle can charge the starting battery before entering the power conservation mode, ensuring that the power battery has sufficient power is also conducive to ensuring that the starting battery has sufficient power, so that the starting battery has sufficient power to start the vehicle when the vehicle is awakened later. The specific value of the first preset power can be determined by simulation or statistical analysis.

[0075] In one embodiment, the vehicle is controlled to enter a power conservation mode according to the operating status of the vehicle, including: when the vehicle is in a parking gear for a preset time, the power level of the vehicle's power battery is higher than or equal to a first preset power level, and the high voltage of the entire vehicle is powered off, the vehicle is controlled to enter a power conservation mode.

[0076] In the embodiment of the present application, one of the conditions for controlling the vehicle to enter the power conservation mode is that the vehicle's gear is in the parking gear for a preset time period. During the preset time period, the vehicle's low-voltage electrical appliances are powered by the starting battery. The existence of the preset time period allows the user to have a certain amount of preparation time. The preset time period may be, for example, 5 minutes.

[0077] For example, the user can control the closing of windows, sunroof, sunshade, trunk, and inhibit the opening of rearview mirrors within the preset time; or, if the user no longer wants the vehicle to enter the power preservation mode within the preset time, the user can cancel entering the power preservation mode within the preset time. Compared with directly entering the power preservation mode and then changing his mind and exiting the power saving mode by activating the starting battery, the setting of the preset time makes the time spent by the user in this case shorter, thereby saving the user's operation time.

[0078] In one embodiment, in response to a first instruction, the vehicle is controlled to enter a power conservation mode according to the operating status of the vehicle, including: in response to the first instruction, obtaining power conservation mode parameters, and when it is determined according to the power conservation mode parameters that the power conservation mode needs to be entered, controlling the vehicle to enter the power conservation mode according to the operating status of the vehicle.

[0079] Among them, the power conservation mode parameters include at least one of the power of the power battery, the vehicle's cruising range and the target transportation distance.

[0080] The power consumption of electrical equipment and the capacity of batteries used in different vehicles may be different, resulting in different mileages for different vehicles. Considering the differences in the distances over which vehicles are transported, for example, some vehicles are sent to other provinces in the country by truck, while other vehicles are exported to other countries overseas by sea, it is possible to determine whether to enter the power conservation mode based on the power conservation mode parameters.

[0081] For example, there are two vehicles A and B that are sent from the same starting point to different destinations. The power of the power batteries of both vehicles is 80% remaining, and the cruising range of the vehicles is 400km. The target transportation distance of vehicle A is 1000km, while the target transportation distance of vehicle B is 4000km. The transportation time required by vehicle B is longer than that required by vehicle A. The transportation process will cause more power loss to vehicle B, and vehicle B needs to save power by entering the power conservation mode. The implementer can determine the specific value of the power conservation mode parameter corresponding to the need to enable the power conservation mode according to actual needs.

[0082] In the embodiment of the present application, it is considered that there may be a situation where the vehicle is not transported for a long time but is not used by the user or the vehicle dealer for a long time. In this case, the user or the vehicle dealer may also want to reduce the power consumption of the vehicle's starting battery. Therefore, in the actual process, whether to turn on the power conservation mode in the embodiment of the present application can also be recommended to the user as an option.

[0083] For example, if it is determined that the power conservation mode needs to be entered, a pop-up window may be displayed on the touch screen or the user may be notified by text message, and the user may choose whether to accept entering the power conservation mode. If the user accepts entering the power conservation mode, the user or the vehicle dealer may control the vehicle to enter the power conservation mode. On the contrary, if the user does not accept entering the power conservation mode, the vehicle will no longer enter the power conservation mode. This can meet the actual needs of the user.

[0084] Taking into account that as an ordinary user of the vehicle, there may be no need to transport the vehicle during the use of the vehicle, and only in order to avoid the starting battery from being depleted due to long-term non-use of the vehicle, the embodiment of the present application can also determine whether to enter the power conservation mode based on the user's choice, no longer based on the power conservation mode parameters, thereby no longer executing this part of the calculation process, and the user will no longer be disturbed by such information, thereby improving the user's operating experience.

[0085] In one embodiment, before controlling the vehicle to enter the power conservation mode, when the power of the starting battery is lower than the second preset power, the power battery of the vehicle can be controlled to charge the starting battery. In this way, the charging process of the starting battery by the power battery can ensure that the starting battery has sufficient power, further avoiding the situation where the starting battery is out of power.

[0086] After the vehicle enters the power conservation mode, the circuit between the starting battery and the power battery will be disconnected, and the power battery will not be able to charge the starting battery. Therefore, in the embodiment of the present application, the charging process of the power battery for the starting battery is arranged before the vehicle enters the power conservation mode, so that the starting battery can be replenished with power in time to avoid the situation where the power battery cannot charge the starting battery after the vehicle enters the power conservation mode.

[0087] In one embodiment, controlling the vehicle to enter a power conservation mode according to the operating state of the vehicle further includes: when the air conditioner of the vehicle is in an on state, controlling the air conditioner to be turned off; when the air conditioner of the vehicle is in an off state, prohibiting the air conditioner from being turned on.

[0088] The air conditioner is one of the most power-consuming electrical devices in the vehicle. By turning off the air conditioner or prohibiting it from being turned on and controlling the vehicle to enter the power conservation mode, the power consumption of the power battery can be reduced to ensure that the power battery of the vehicle has sufficient power.

[0089] S2300: When the vehicle enters the power conservation mode, control the battery management system of the vehicle to disconnect the external power supply of the starting battery of the vehicle.

[0090] The starting battery in the embodiment of the present application can be a starting battery such as a lithium iron phosphate battery, a lead-acid battery, etc., and the specific type of the starting battery is not limited here.

[0091] In one embodiment, the battery management system is controlled to set the discharge branch of the starter battery to a disconnected state, so that the external power supply of the starter battery can be disconnected. The discharge branch of the starter battery is set to be disconnected, which specifically refers to disconnecting the relay set on the discharge branch; the relay can be controlled by the controller, and when the vehicle enters the power conservation mode, the controller controls the relay on the discharge branch to disconnect. When the relay of the discharge branch of the starter battery is set to a disconnected state, the starter battery will not be able to continue to supply power to the outside, thereby effectively reducing the power consumption of the starter battery.

[0092] When the vehicle enters the power conservation mode, the status of the vehicle's target facilities can be detected; when the target facilities are in a preset state, the battery management system is controlled to disconnect the external power supply of the starting battery; when the target facilities are in a non-preset state, the target facilities are adjusted to be in a preset state, and the battery management system is controlled to disconnect the external power supply of the starting battery.

[0093] In an embodiment of the present application, the facilities provided on the vehicle may be vehicle windows, sunroofs, sunshades, vehicle windows, tailgates, etc. Disconnecting the external power supply of the starting battery requires that these facilities are in a preset state, for example, the vehicle's sunroof is closed.

[0094] The shutdown process of some facilities requires power supply from the starting battery, or it is more convenient for users to shut down by powering the starting battery. After the starting battery disconnects the external power supply, the starting battery will not be able to power these facilities. Therefore, in an embodiment of the present application, when the target facility is in a preset state, or after the target facility is adjusted to a preset state, the battery management system is controlled to disconnect the external power supply of the starting battery, which can facilitate user operation and avoid unnecessary losses to users caused by these facilities not being adjusted to the preset state.

[0095] In power conservation mode, the starting battery does not supply power to the outside. The power consumption of the starting battery comes from the self-inspection process of its internal modules. The power consumption of the internal modules of the starting battery is lower than that of the external power supply of the starting battery, which can reduce the power consumption of the starting battery, thereby increasing the possibility that the starting battery still has enough power to start the vehicle after the vehicle has been idle for a long time.

[0096] After controlling the battery management system of the vehicle to disconnect the external power supply of the starting battery of the vehicle, the battery management system can also be controlled to start the external power supply of the starting battery to exit the power conservation mode when the micro switch of the vehicle body is triggered.

[0097] A micro switch has a small contact spacing and a snap-action mechanism. It is a contact mechanism that can perform a switch action with a preset stroke and a preset force. Because the contact spacing of the switch is relatively small, it is called a micro switch, also known as a sensitive switch. Among them, the micro switch can be set in a position that is convenient for users to operate, such as the front door handle of the vehicle.

[0098] By triggering the micro switch, the user can start the starting battery to supply power to the outside. The starting battery will send an enable signal to wake up the control circuit board and control the relay to close to start the vehicle. After that, the user can control the vehicle.

[0099] Since the embodiment of the present application does not require the user to disconnect the negative pole of the starting switch to reduce the power consumption of the starting battery, when the user needs to use the vehicle, that is, when the vehicle needs to exit the power conservation mode, there is no need to manually connect the negative pole of the starting battery. The vehicle can be awakened by triggering the micro switch, which reduces the operational threshold for the user to start the vehicle and can improve the user experience.

[0100] After the vehicle is started, the power battery can convert the voltage through the DC / DC converter and continue to supply power to the low-voltage electrical equipment on the vehicle.

[0101] In one embodiment, after the micro switch is triggered, the user can enter the vehicle after opening the door, and obtain driving authority for the vehicle if the identity information is verified.

[0102] The vehicle control method provided in the embodiment of the present application can control the external power-off of the starting battery through the software system when the vehicle enters the power conservation mode. The user does not need to unplug the negative pole of the starting battery, which lowers the user's operation threshold and can reduce the power loss of the starting battery, thereby reducing the possibility of the starting battery running out of power due to long-term parking.

[0103] The following is a specific example to illustrate the process of the vehicle entering the power conservation mode. Figure 3 As shown, the following steps may be included.

[0104] Step S3100: The vehicle is idle for a long time or actively requests to enter the power conservation mode.

[0105] Among them, long-term parking of a vehicle means that the vehicle has not been used for a long time after parking. For example, if the vehicle has not been used for 7 days after parking, the vehicle can automatically execute step S3100.

[0106] The vehicle may also receive a first instruction to enter a power conservation mode. In response to the first instruction, the vehicle may be controlled to enter the power conservation mode according to the operating state of the vehicle.

[0107] The user may send the first instruction by performing a touch operation on a touch screen provided on the vehicle.

[0108] In step S3200, the domain controller takes the initiative to determine whether the vehicle is powered off.

[0109] If the vehicle is powered off, execute step S3300; if the vehicle is powered on, execute step S3400.

[0110] Step S3300, the domain controller automatically closes the car windows, sunroof, and trunk.

[0111] Step S3400: The VCU (Vehicle Control Unit) limits the speed of the vehicle and controls the vehicle to automatically power off after being in gear P for 5 minutes.

[0112] Step S3500, start the battery LBMS to determine whether it meets the requirements for entering smart charging.

[0113] If the starting battery does not meet the requirements for entering smart charging, execute step S3600 to put the vehicle into power conservation mode.

[0114] If the starting battery meets the requirements for entering smart charging, step S3700 is executed to perform smart charging on the starting battery; wherein, smart charging of the starting battery refers to using the vehicle's power battery to charge the starting battery so that the vehicle enters the power conservation mode after the starting battery has sufficient power. In the subsequent process of using the starting battery to start the vehicle, the situation where the starting battery is insufficient to start the vehicle can be avoided.

[0115] <Device Example>

[0116] The present disclosure provides a vehicle control device 40. Figure 4 The system shown includes: a receiving module 41, a first control module 42, and a second control module 43. Among them:
