[0048] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0049] The vehicle control method provided in the embodiment of the present application can be applied to Figure 1 In the application environment shown. Among them, the terminal 102 communicates with the vehicle to be controlled 104 through the network. The data storage system can store the data that the terminal 102 needs to process. The data storage system can be integrated on the terminal 102, or it can be placed on the cloud or other network servers. The terminal 102 can be an electronic control unit (ECU) integrated in the vehicle to be controlled 104, or it can be a terminal device independent of the vehicle to be controlled 104. There is at least one comfort load in the vehicle to be controlled 104, and the target comfort load 106 is one of the at least one comfort load. The terminal 102 obtains the energy reserve state and the low-voltage power grid fault state of the vehicle to be controlled 104; determines the energy limit level according to the energy reserve state and the low-voltage power grid fault state; determines the energy limit mode corresponding to the energy limit level, and sends a target energy limit request to the corresponding target comfort load 106 according to the energy limit mode, so as to instruct the target comfort load 106 to respond to the target energy limit request. The terminal 102 may be, but is not limited to, various personal computers, laptops, smart phones, tablet computers, IoT devices, and portable wearable devices. The IoT devices may be smart speakers, smart TVs, smart air conditioners, smart vehicle-mounted devices, and projection devices. Portable wearable devices may be smart watches, smart bracelets, head-mounted devices, and the like. Head-mounted devices may be virtual reality (VR) devices, augmented reality (AR) devices, smart glasses, and the like. The vehicle to be controlled 104 may be an electric vehicle, a fuel vehicle, or a hybrid vehicle.

[0050] In an exemplary embodiment, Figure 2 As shown, a vehicle control method is provided, which is applied to Figure 1 The terminal 102 in the example is used as an example to illustrate, including the following steps 202 to 206. Among them:

[0051] Step 202, obtaining the energy reserve state and low-voltage grid fault state of the vehicle to be controlled.

[0052] Among them, the vehicle to be controlled can be an electric vehicle, a fuel vehicle or a hybrid vehicle, so the terminal can be a VCU (Vehicle Control Unit), ECU (Electronic Control Unit) or HCU (Hybrid Control Unit).

[0053] The energy reserve state refers to the state of the energy stored in the vehicle to be controlled. For example, if the remaining reserve energy is lower than the preset energy value, it is a low energy reserve state, and if it is not lower than the preset energy value, it is a high energy reserve state. For example, for electric vehicles, the energy reserve refers to the remaining power; for fuel vehicles, the energy reserve refers to the remaining fuel in the tank.

[0054] The low-voltage grid fault state refers to the fault state of the low-voltage grid of the vehicle to be controlled. The low-voltage grid is used to provide necessary power to the electronic control unit, sensor, lighting system, etc. of the vehicle. For example, for an electric vehicle, the low-voltage grid fault may be a fault in the DC-DC converter (DC-to-DC converter), and for a fuel vehicle, the low-voltage grid fault may be an electrical or mechanical fault in the generator.

[0055] Step 204: determine the energy limit level according to the energy reserve state and the low voltage grid fault state.

[0056] The energy limit level refers to the level of energy limit for the controlled vehicle. For example, the energy limit level includes the first energy limit level, the second energy limit level, etc. The energy limit for the controlled vehicle mainly refers to the energy limit for the comfort load in the controlled vehicle. Since the comfort load does not affect the driving function of the vehicle, a certain degree of energy limit for the comfort load is conducive to saving the energy consumption of the controlled vehicle.

[0057] Different energy limit levels can be determined for different energy reserve states and low-voltage power grid fault states, so as to impose different degrees of energy limit on comfort loads.

[0058] For example, the terminal presets a mapping relationship between energy reserve status, low-voltage power grid fault status, and energy limit level. By querying the mapping relationship, the energy limit level can be quickly determined.

[0059] Step 206 : determining an energy limitation mode corresponding to the energy limitation level, and sending a target energy limitation request to the corresponding target comfort load according to the energy limitation mode, so as to instruct the target comfort load to perform energy limitation response according to the target energy limitation request.

[0060] Among them, comfort load refers to equipment that improves the comfort of the vehicle to be controlled. For example, comfort load includes seats with heating, ventilation or massage functions, audio, screens, ambient lights, heated windshields, heated exterior mirrors, heated steering wheels, plug-and-play charging equipment, wireless charging equipment, etc.

[0061] The energy-limited mode refers to a mode that uses different control strategies for different comfort loads. Different energy-limited levels correspond to different energy-limited modes. The terminal pre-stores a mapping relationship between energy-limited levels and energy-limited modes. By searching the mapping relationship, the energy-limited mode corresponding to the energy-limited level can be obtained. For example, the energy-limited mode corresponding to the first energy-limited level includes turning off the rear window heating function and the steering wheel heating function. The energy-limited mode corresponding to the second energy-limited mode includes turning off the air volume of the air conditioner and the seat heating function.

[0062] The target comfort load is the comfort load indicated by the energy limit mode. The target energy limit request is a request generated according to the energy limit mode, and the terminal sends the target energy limit request to the target comfort load corresponding to the energy limit mode. The energy limit response refers to the response of the target comfort load to the target energy limit request.

[0063] In the above vehicle control method, the energy reserve state and low-voltage grid fault state of the vehicle to be controlled are obtained; the energy limit level is determined according to the energy reserve state and the low-voltage grid fault state; the energy limit mode corresponding to the energy limit level is determined, and a target energy limit request is sent to the corresponding target comfort load according to the energy limit mode to instruct the target comfort load to respond to energy limit according to the target energy limit request. In the above scheme, the energy limit level is determined by the energy reserve state and low-voltage grid fault state of the vehicle to be controlled, and the energy limit mode corresponding to the energy limit level is determined. Since the energy limit mode can be determined according to different energy reserve states and low-voltage grid fault states, the target comfort load is instructed to respond to energy limit according to the target energy limit request corresponding to the energy limit mode. This can ensure that the vehicle can flexibly limit the comfort load under different energy reserve states and low-voltage grid fault states, so that the energy limit response of the comfort load is more in line with user needs.

[0064] In an exemplary embodiment, the vehicle to be controlled is an electric vehicle; the energy limitation level is determined according to the energy reserve state and the low-voltage power grid fault state, including: when the low-voltage power grid fault state indicates that the DC converter does not have a first preset fault, the battery is not in a long-term discharge state, and the energy reserve state indicates that the power battery power is lower than the first preset power, or, when the low-voltage power grid fault state indicates that the DC converter does not have a first preset fault, the battery is not in a long-term discharge state, and the remaining driving range is lower than the preset mileage, the energy limitation level is determined to be the first energy limitation level; when the low-voltage power grid fault state indicates that the DC converter has a first preset fault, or the battery is in a long-term discharge state, the energy limitation level is determined to be the second energy limitation level.

[0065] For electric vehicles, the energy limit level is determined mainly based on the DC converter fault condition, battery charge and discharge condition, power battery capacity, and remaining driving range. The DC converter is a DC (or approximate DC) power source that can convert a DC power source into a DC power source of different voltages. The first preset fault refers to a serious fault that causes the DC converter to fail to output normally.

[0066] The fact that the battery is not in a long-term discharge state indicates that the battery is in a charging state within a preset time period. The power battery power is lower than the first preset power and the remaining driving range is lower than the preset range, both indicating that the power battery power is insufficient to maintain the preset range.

[0067] For electric vehicles, the first energy limit level refers to the energy limit level when the DC converter fault state is good and the battery is in a charging state, but the power battery power or remaining driving range is insufficient; the second energy limit level refers to the energy limit level when the DC converter is in a fault state or the battery is continuously discharging.

[0068] In this embodiment, different energy limit levels of the electric vehicle are determined from multiple angles, including the DC converter fault state, battery charge and discharge state, and energy reserve state. The comfort load can be flexibly limited according to actual conditions, so that the energy limit response of the comfort load is more in line with user needs.

[0069] In an exemplary embodiment, the vehicle control method also includes: determining that energy limitation is not required when the energy reserve status indicates that the power battery power is not less than a first preset power, the remaining cruising range is not less than a preset range, the low-voltage grid fault status indicates that the DC converter does not have a first preset fault, and the battery is not in a long-term discharge state.

[0070] Among them, for electric vehicles, energy limitation is not required when the DC converter is in good fault condition, the battery is in a charging state, the power battery has sufficient power, and the remaining driving range is sufficient.

[0071] In this embodiment, by determining not to limit energy when the DC converter of the electric vehicle is in good fault state, the battery is in a charging state, the power battery has sufficient power, and the remaining driving range is sufficient, it is helpful to ensure that all comfort loads are in an available state and the user's comfort requirements for the controlled vehicle are met.

[0072] In an exemplary embodiment, the vehicle to be controlled is a fuel vehicle; the energy limit level is determined according to the energy reserve state and the low-voltage power grid fault state, including:

[0073] When the low-voltage grid fault state indicates that the generator does not have the second preset fault, the battery is not in a long-term discharge state, and the energy reserve state indicates that the remaining oil amount in the oil tank is lower than the preset oil amount, the energy limit level is determined to be the first energy limit level;

[0074] When the low-voltage grid fault state indicates that the generator has a second preset fault, or the storage battery is in a long-term discharge state, the energy limit level is determined to be the second energy limit level.

[0075] For fuel vehicles, the energy limit level is mainly determined by the generator fault condition, battery charge and discharge condition and the remaining fuel in the tank. The second preset fault refers to the electrical or mechanical fault of the generator. The remaining fuel in the tank refers to the volume of the remaining fuel in the tank of the fuel vehicle. The preset fuel volume is the fuel volume required for the vehicle to be controlled to travel a preset mileage.

[0076] For fuel vehicles, the first energy limit level refers to the energy limit level when the generator fault state is good, the battery is in a charging state, but the remaining fuel in the tank is insufficient; the second energy limit level refers to the energy limit level when the generator is in a fault state or the battery is continuously discharging.

[0077] In this embodiment, different energy limit levels of fuel vehicles are determined from multiple angles, including generator fault status, battery charging and discharging status, and fuel tank remaining fuel status. The comfort load can be flexibly limited according to actual conditions, making the energy limit response of the comfort load more in line with user needs.

[0078] In an exemplary embodiment, the vehicle control method also includes: determining that energy limitation is not required when the low-voltage grid fault state indicates that the generator does not have a second preset fault, the battery is not in a long-term discharge state, and the energy reserve state indicates that the remaining fuel amount in the tank is not less than a preset fuel amount.

[0079] Among them, for fuel vehicles, energy limitation is not required when the generator fault condition is good, the battery is in a charging state, and there is sufficient fuel remaining in the tank.

[0080] In this embodiment, by determining not to limit energy when the fuel vehicle generator is in good condition, the battery is in a charging state, and the remaining fuel in the tank is sufficient, it is helpful to ensure that all comfort loads are in an available state and to ensure the user's comfort requirements for the controlled vehicle.

[0081] In an exemplary embodiment, determining the energy limiting mode corresponding to the energy limiting level includes: obtaining a pre-stored mapping relationship between different energy limiting levels and energy limiting modes, querying the mapping relationship, and obtaining the energy limiting mode corresponding to the energy limiting level; or, displaying an energy limiting mode setting interface on the central control screen, and determining the energy limiting mode corresponding to the energy limiting level in response to the user's selection operation on each functional module in the energy limiting mode setting interface.

[0082] Among them, in some embodiments, there is a preset mapping relationship between the energy limit mode and the energy limit level, and by querying the mapping relationship, the energy limit mode corresponding to the energy limit level can be determined. The energy limit mode includes a first energy limit mode and a second energy limit mode, the first energy limit mode is an energy limit mode corresponding to the first energy limit level, and the second energy limit mode is an energy limit mode corresponding to the second energy limit level. Table 1 is a preset mapping relationship table in an embodiment.

[0083] Table 1 Preset mapping relationship table

[0084]

[0085] At the same time, in order to meet the user's personalized use needs for comfort loads, the energy-limiting mode can also be flexibly adjusted according to the user's selected operation. In other embodiments, a central control screen is deployed in the vehicle to be controlled, and the central control screen can be a human-computer interaction interface, and multiple interfaces can be displayed in the central control screen. The energy-limiting mode setting interface is used to display the use status of each comfort load under multiple energy-limiting modes, and provides a corresponding user operation area.

[0086] like Figure 3The figure shows a schematic diagram of an energy-limited mode setting interface in one embodiment. The energy-limited mode setting interface includes multiple functional modules, namely, a limited function module, a first energy-limited mode setting module, and a second energy-limited mode setting module. Among them, the limited function module displays a variety of comfort loads, and the first energy-limited mode setting module and the second energy-limited mode setting module respectively include adjustment areas for each comfort load. For example, the switch state adjustment area of ​​the rear window heating can use a switch button. The gear adjustment area of ​​the air volume of the air conditioner can use a slider control. For air conditioning air volume, seat heating, seat ventilation, screen brightness, audio volume, and ambient light brightness, gear limits are set according to the corresponding functions. Users can adjust the gear at will. Setting it to the highest gear means that this function is not restricted in energy limited mode, and setting it to 0 means that this function is directly turned off in energy limited mode. For functions such as rear window heating, exterior mirror heating, steering wheel heating, seat massage, USB charging, and mobile phone wireless charging that have no gear limits and only have switches, a switch button is left in the setting interface. When set to on, it means that this function is not restricted in energy limited mode, and when set to off, it means that this function is directly turned off in energy limited mode.

[0087] The terminal implements the energy limiting mode corresponding to each energy limiting level in response to the user's selection operation on each adjustment area in the first energy limiting mode setting module or the second energy limiting mode setting module. The setting content in the first energy limiting mode setting module determines the energy limiting condition of each comfort load in the first energy limiting mode, and the setting content in the second energy limiting mode setting module determines the energy limiting condition of each comfort load in the second energy limiting mode. After the user has personalized the energy limiting modes, the terminal will update the pre-stored mapping relationship between different energy limiting levels and energy limiting modes, or save the updated mapping relationship between each energy limiting level and energy limiting mode.

[0088] like Figure 4 The figure shows a user-defined logic diagram in an embodiment. After entering the energy limit mode setting interface, the mapping relationship obtained after the setting is stored in response to the user's setting of each comfort load in the first energy limit mode or the second energy limit mode. When it is detected that the conditions corresponding to the first energy limit level or the second energy limit level are met, a corresponding entry prompt is generated, and energy is limited according to the stored mapping relationship. When the first energy limit level is not detected and the conditions corresponding to the second energy limit level are not detected, no energy limitation is performed.

[0089] In this embodiment, the mapping relationship is pre-stored to facilitate the rapid determination of the energy limiting mode corresponding to the different energy limiting levels; the terminal also provides an interface for user personalized settings. After the user has personalized the energy limiting modes, the mapping relationship can be updated or re-saved so that the next time the scene is triggered, the energy limiting request is sent according to the user setting results until the user changes the settings.

[0090] To explain the vehicle control method and effect in this solution in detail, a most detailed embodiment is described below:

[0091] The vehicle control method can be applied to electric vehicles, fuel vehicles or hybrid vehicles. Figure 5 The figure shows a block diagram of the energy limiting principle of the vehicle control method in an embodiment. Among them, an intelligent control system is deployed in the terminal, and the intelligent control system obtains the remaining driving range of the electric vehicle through the HCU controller, obtains the power battery power of the electric vehicle through the BMS (Battery Management System) controller, obtains the fault state and working state of the DC converter of the electric vehicle through the DC-DC controller, obtains the battery current through the EBS (Electronic Brake Systems) sensor, obtains the electrical or mechanical fault of the generator of the fuel vehicle through the generator regulator, and obtains the remaining fuel in the fuel tank of the fuel vehicle through the EMS (Energy Management System) controller. The intelligent control system processes the above-mentioned information, generates an energy limiting prompt, and displays it through the instrument cluster. The intelligent control system also sends a target energy limiting request to each target comfort load to instruct the target comfort load to respond to the target energy limiting request.

[0092] like Figure 6 FIG. 1 is a flow chart of a vehicle control method for an electric vehicle in one embodiment. Figure 7 The figure shows a flow chart of a vehicle control method for a fuel vehicle in an embodiment. The intelligent control system determines the vehicle state through the information obtained above, thereby determining the energy limit level and energy limit mode of the electric vehicle or fuel vehicle, and then sends a target energy limit request to instruct the target comfort load to respond to the target energy limit request.

[0093] In addition to the default energy limit setting of the intelligent control system, the specific definition of energy limit also supports active setting by users. In the central control screen, a user setting interface for energy limit mode will be opened, which supports users to independently set the energy limit mode corresponding to the first energy limit mode and the second energy limit mode. The intelligent control system will memorize the user's settings, and when the energy limit conditions are met next time, the intelligent control system will limit energy according to the user's settings.

[0094] The above vehicle control method obtains the energy reserve status and low-voltage grid fault status of the vehicle to be controlled; determines the energy limit level according to the energy reserve status and the low-voltage grid fault status; determines the energy limit mode corresponding to the energy limit level, and sends a target energy limit request to the corresponding target comfort load according to the energy limit mode, so as to instruct the target comfort load to respond with energy limit according to the target energy limit request. The above scheme determines the energy limit level according to the energy reserve status and low-voltage grid fault status of the vehicle to be controlled, and determines the energy limit mode corresponding to the energy limit level. Since the energy limit mode can be determined according to different energy reserve status and low-voltage grid fault status, the target comfort load is instructed to respond with energy limit according to the target energy limit request corresponding to the energy limit mode. This can ensure that the vehicle can flexibly limit the comfort load under different energy reserve status and low-voltage grid fault status, so that the energy limit response of the comfort load is more in line with user needs.

[0095] It should be understood that, although the various steps in the flowcharts involved in the above-mentioned embodiments are displayed in sequence according to the indication of the arrows, these steps are not necessarily executed in sequence according to the order indicated by the arrows. Unless there is a clear explanation in this article, the execution of these steps does not have a strict order restriction, and these steps can be executed in other orders. Moreover, at least a part of the steps in the flowcharts involved in the above-mentioned embodiments can include multiple steps or multiple stages, and these steps or stages are not necessarily executed at the same time, but can be executed at different times, and the execution order of these steps or stages is not necessarily to be carried out in sequence, but can be executed in turn or alternately with other steps or at least a part of the steps or stages in other steps.

[0096] Based on the same inventive concept, the embodiment of the present application also provides a vehicle control device for implementing the vehicle control method involved above. The implementation scheme for solving the problem provided by the device is similar to the implementation scheme recorded in the above method, so the specific limitations in one or more vehicle control device embodiments provided below can refer to the limitations on the vehicle control method above, and will not be repeated here.

[0097] In an exemplary embodiment, Figure 8 As shown, a vehicle control device 100 is provided, comprising: an acquisition module 120, a determination module 140 and an energy limiting module 160, wherein:

[0098] An acquisition module 120 is used to acquire the energy reserve state and low-voltage power grid fault state of the vehicle to be controlled;

[0099] A determination module 140, configured to determine an energy limit level according to an energy reserve state and a low voltage grid fault state;
