[0002] With the development of new energy vehicles, hybrid vehicles can effectively eliminate the anxiety of pure electric vehicles in terms of range and charging, so hybrid vehicles are very popular among consumers. When hybrid vehicles are in pure electric state, long-term driving or charging will cause the battery's state of charge to decrease. When the state of charge decreases to a certain level, the vehicle will lose power, affecting the normal use of the vehicle.

[0003] In the related art, if a hybrid vehicle needs to be transported for a long time, the battery of the hybrid vehicle is prone to power loss, so the vehicle needs to be charged in time. However, during the transportation process, if the battery of the vehicle cannot be charged in time, the battery of the vehicle will be over-discharged for a long time, which will cause irreversible damage to the battery.

[0044] The technical solution in the present application will be described clearly and in detail below in conjunction with the accompanying drawings. In the description of the embodiments of the present application, unless otherwise specified, " / " means or, for example, A / B can mean A or B: "and / or" in the text is only a description of the association relationship of associated objects, indicating that there can be three relationships, for example, A and / or B can mean: A exists alone, A and B exist at the same time, and B exists alone. In addition, in the description of the embodiments of the present application, "multiple" means two or more than two.

[0045] In the following, the terms "first" and "second" are used for descriptive purposes only and are not to be understood as suggesting or implying relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features.

[0046] In the vehicle industry, vehicles need to be transported to various locations after leaving the factory. During long-distance transportation, the vehicle may be started and stopped many times. In this case, the power of the vehicle's battery and power battery will continue to be consumed.

[0047] In the related art, the power of the power battery is replenished by a charging pile. If the power of the power battery is within a preset power range, the power battery can charge the storage battery to prevent the storage battery from being too low. However, during long-distance transportation, the vehicle cannot find a charging pile in time to charge the power battery, which will cause the vehicle's power battery to be over-discharged for a long time and the power battery cannot charge the storage battery, resulting in irreversible damage to both the power battery and the storage battery.

[0048] Figure 1 It is a schematic diagram of an implementation environment of a vehicle control method provided in an embodiment of the present application.

[0049] For example, Figure 1 As shown, the implementation environment includes a vehicle control unit (VCU) 101 and a battery management system 102 .

[0050] The vehicle controller 101 is an important control unit of the vehicle, which can obtain relevant data of the vehicle and control the vehicle to perform corresponding operations based on the relevant data, for example, obtaining the battery status parameters of the vehicle and determining whether to control the vehicle to charge the battery based on the battery status parameters. In some embodiments, the vehicle controller 101 can receive the battery status parameters collected by the battery management system 102 and determine whether to start the vehicle's engine to charge the vehicle's power battery based on the battery status parameters.

[0051] The battery management system 102 is a system for monitoring and managing the battery operating status, which can detect the battery status parameters of the vehicle and implement various battery management functions based on the battery status parameters. In some embodiments, the battery management system 102 sends the battery status parameters of the vehicle to the vehicle controller 101, so that the vehicle controller 101 controls the vehicle to perform corresponding operations based on the battery status parameters.

[0052] Before introducing the method of the embodiment of the present application, the implementation architecture and working principle of a vehicle control method on which the embodiment of the present application relies are first introduced.

[0053] Figure 2 It is a schematic diagram of an implementation architecture of a vehicle control method provided in an embodiment of the present application.

[0054] For example, Figure 2 As shown, the vehicle is a hybrid vehicle. A hybrid vehicle is a car equipped with both a traditional internal combustion engine (such as a gasoline or diesel engine) and an electric motor. The vehicle's structure includes a power battery 201, a high-voltage wiring harness 202, a PTC (Positive Temperature Coefficient) heater 203, an electric motor 204, a voltage converter 205, a battery 206, a starter 207, an engine 208, and a generator 209.

[0055] In some embodiments, Figure 2 As shown, the power battery 201 is connected to the high-voltage electrical equipment through the high-voltage wire harness 202. The high-voltage electrical equipment includes a PTC heater 203, a motor 204 or a voltage converter 205 and other equipment. The storage battery 206 is connected to the voltage converter 205 in the high-voltage electrical equipment. The negative electrode of the power battery 201 is connected to the negative electrode of the generator 209, and the positive electrode of the power battery 201 is connected to the positive electrode of the generator 209.

[0056] In some embodiments, Figure 2 As shown, the power battery 201 drives components such as the motor 204, the PTC heater 203 and the voltage converter 205 through high-voltage direct current.

[0057] The voltage converter 205 is used to convert the high-voltage direct current of the power battery into the low-voltage direct current required by the storage battery 206 to replenish the power of the storage battery 206 .

[0058] The electric motor 204 is used to drive the engine 208 to charge the power battery 201. In some embodiments, the electric motor 204 is used to convert the electrical energy of the power battery 201 into kinetic energy to drive the vehicle.

[0059] The engine 208 is used to drive the generator 209 to convert the mechanical energy generated by the engine 208 into electrical energy to charge the power battery 201 .

[0060] The battery 206 is used to drive the starter 207 , so that the starter 207 converts the electrical energy of the battery 206 into mechanical energy, thereby driving the gears on the starter 207 .

[0061] The starter 207 is used to drive the engine 208 to charge the power battery 201 .

[0062] With respect to the above-mentioned vehicle structure, when the vehicle implements the method of the embodiment of the present application, the specific process is roughly summarized as follows:

[0063] When the power battery 201 transmits high-voltage direct current to the motor 204, the high-voltage direct current drives the motor 204 to rotate, and the gears on the motor 204 also rotate. The gears of the motor 204 mesh with the gears on the engine 208. When the gears of the motor 204 rotate, the gears on the engine 208 also rotate, thereby driving the engine 208 to start.

[0064] When the battery 206 transmits low-voltage direct current to the starter 207, the low-voltage direct current drives the starter 207 to rotate, and the gear on the starter 207 also rotates. The gear of the starter 207 meshes with the gear on the engine 208. When the gear of the starter 207 rotates, the gear on the engine 208 also rotates, so that the piston inside the engine moves, and then the combustion cycle inside the engine is started, that is, the engine 208 is started.

[0065] The engine 208 is connected to the generator 209 via a belt or gear. When the engine 208 starts to rotate, the generator 209 is driven to start via the belt or gear, thereby converting the mechanical energy of the engine 208 into electrical energy. The generator 209 transmits the electrical energy to the power battery 201 to charge the power battery 201.

[0066] After introducing the architecture and working principle of the vehicle of the embodiment of the present application, a vehicle control method provided by the embodiment of the present application is introduced below.

[0067] Figure 3 It is a schematic flow chart of a vehicle control method provided in an embodiment of the present application.

[0068] For example, Figure 3 As shown, taking the execution subject as a vehicle controller as an example, the method 300 includes:

[0069] Step 301, when the vehicle is in a power conservation mode, obtaining the voltage state of the vehicle, the power conservation mode is used to maintain the power level of the vehicle's power battery within a preset power range.

[0070] During long-distance transportation, although the vehicle is in a dormant state, the anti-theft system, positioning system and clock circuit of the vehicle are all in a consumption state. In this case, the vehicle will generate standby power consumption, so the vehicle's battery needs to provide power to the vehicle's standby equipment, and the battery power will be continuously consumed. In this case, the vehicle's power battery will replenish the battery, so the power in the power battery will be consumed. In order to prevent the vehicle's power battery from being too low, the vehicle needs to enter the power conservation mode to maintain the power of the power battery within the preset power range.

[0071] Among them, the voltage state of the vehicle includes a high voltage state and a low voltage state. The high voltage state of the vehicle generally indicates that the high voltage electrical system in the vehicle is in a working state, that is, the high voltage electrical system is responsible for providing a high voltage voltage. For example, when the vehicle is in a high voltage state, the high voltage electrical system of the vehicle drives high voltage equipment such as the motor in the vehicle. The low voltage state of the vehicle generally indicates that the low voltage electrical system of the vehicle is in a working state, that is, the low voltage electrical system is responsible for providing a low voltage voltage. For example, when the vehicle is in a low voltage state, the low voltage electrical system of the vehicle drives low voltage electrical equipment such as the audio system of the vehicle.

[0072] The preset power range is automatically determined by the vehicle controller or set by the technician according to the actual situation, and the present application embodiment does not limit this. For example, the preset power range can be 60% to 20%.

[0073] For example, when the vehicle is in power conservation mode, the power level of the vehicle's power battery is maintained between 20% and 60%.

[0074] Step 302 : determining a target engine starting mode of the vehicle based on a voltage state of the vehicle, where different voltage states correspond to different engine starting modes.

[0075] The target engine starting mode is used to start the engine to preserve the power of the power battery. The engine starting mode includes the motor starting mode corresponding to the power battery and the starter starting mode corresponding to the storage battery. Different voltage states correspond to different engine starting modes.

[0076] It should be understood that the power battery cannot be charged during long-distance transportation, and the voltage state of the vehicle will change. In this case, different engine starting methods are determined according to different voltage states, which can cope with the voltage state changes during vehicle transportation, thereby maintaining the power battery under various voltage states.

[0077] Step 303, controlling the vehicle to start the engine in a target engine starting mode to preserve the power battery.

[0078] Among them, the vehicle is controlled to start the engine, and the engine can convert the chemical energy of the fuel in the vehicle into electrical energy. Therefore, after starting the engine, the power battery can be maintained.

[0079] During long-distance transportation, the vehicle's power battery will be in an unchargeable state for a long time. If the power battery cannot be replenished in time after it is exhausted, it will need to be maintained through complex maintenance methods. For example, the battery is balanced through a battery equalizer to ensure that the voltage of each single cell in the power battery is consistent. To avoid this situation, the vehicle is controlled to start the engine in the target engine start mode, and the chemical energy of the fuel in the vehicle is converted into electrical energy through the engine to maintain the power battery, thereby reducing and avoiding the increase in the cost of maintaining the power battery.

[0080] An embodiment of the present application provides a vehicle control method, which can obtain the voltage state of the vehicle when the vehicle is in a power conservation mode, and the power conservation mode is used to maintain the power of the vehicle's power battery within a preset power range. During long-distance transportation, the voltage state of the vehicle will change. Therefore, based on the voltage state of the vehicle, the target engine start mode of the vehicle is determined. Different voltage states correspond to different engine start modes. The vehicle is controlled to start the engine in the target engine start mode to conserve power for the power battery. In this case, even if the vehicle is in a long-distance transportation process, the power of the vehicle's power battery will be maintained within the preset power range, effectively avoiding the vehicle's power battery from being depleted for a long time.

[0081] Figure 4 It is a schematic flow chart of a vehicle control method provided in an embodiment of the present application.

[0082] It should be noted that the above steps 301-303 are a simple description of a vehicle control method provided in an embodiment of the present application. The following will provide a more detailed description of a vehicle control method provided in an embodiment of the present application in combination with some examples. Figure 4 Taking the execution subject as the vehicle controller as an example, the method includes the following steps:

[0083] Step 401, determining whether the vehicle is in a power conservation mode, where the power conservation mode is used to maintain the power level of the vehicle's power battery within a preset power range.

[0084] It should be understood that if the vehicle is in the process of long-distance transportation, the vehicle's battery cannot be charged in time. In this case, in order to avoid the vehicle's battery being depleted for a long time, the vehicle's power conservation mode needs to be turned on. However, the power conservation mode is suitable for long-distance transportation. If a button to turn on the power conservation mode is redeveloped, the vehicle's subsequent maintenance costs will increase. In order to avoid the above problems, whether to turn on the power conservation mode is determined based on the vehicle's existing components to avoid increasing the vehicle's subsequent maintenance costs.

[0085] The following describes how to determine whether the vehicle should start the power conservation mode based on the mileage.

[0086] In a possible implementation, the mileage of the vehicle is obtained, and whether the vehicle turns on the power conservation mode is determined based on the mileage.

[0087] Among them, mileage refers to the total kilometers traveled by the vehicle after the vehicle is produced.

[0088] The preset mileage is automatically determined by the vehicle controller, or is set by the technician according to the actual situation, and the present application embodiment does not limit this. For example, the preset mileage may be 2.6 kilometers (KM).

[0089] It should be understood that in actual applications, the preset mileage may be different due to different vehicle models.

[0090] It should be understood that the vehicle needs to be tested for its functions before it leaves the factory, and can only be transported to other places after the test is completed. For example, the vehicle needs to be tested on the road to verify whether the vehicle is qualified. Therefore, the mileage of the vehicle will change before the vehicle is transported. In this case, whether to turn on the power conservation mode is determined based on the mileage of the vehicle.

[0091] In this implementation, only the vehicle's mileage is needed to determine whether the vehicle is in power conservation mode, and no other modules need to be reintegrated in the cabin. In this case, not only can the vehicle's power battery be prevented from running out of power for a long time, but also the subsequent maintenance cost of the vehicle can be avoided.

[0092] In order to explain the above implementation in more detail, the above implementation is explained in several parts below.

[0093] The first part explains how to obtain the vehicle's mileage.

[0094] In a possible implementation, the mileage of the vehicle is acquired based on a vehicle speed sensor.

[0095] Among them, the vehicle speed sensor is used to determine the wheel speed of the vehicle.

[0096] In some embodiments, a wheel speed signal is acquired based on a vehicle speed sensor; and the mileage of the vehicle is determined based on the wheel speed and the time when the wheel speed is acquired.

[0097] In this implementation manner, the mileage of the vehicle is obtained based on the vehicle speed sensor, so that the mileage of the vehicle can be accurately obtained.

[0098] The second part explains how to determine whether the vehicle should turn on the power conservation mode based on the mileage.

[0099] It should be understood that if a button for controlling the power conservation mode is integrated into the vehicle's on-board equipment or a button for controlling the power conservation mode is set in the cabin, the risk of failure of the vehicle's on-board equipment will increase and the difficulty of repairing the buttons inside the cabin will increase. Therefore, in order to avoid the above situation, whether the vehicle's power conservation mode is turned on is determined based on the mileage.

[0100] In some embodiments, when the driving mileage is greater than or equal to a preset mileage, it is determined that the vehicle is in power conservation mode.

[0101] For example, when the mileage of the vehicle is greater than or equal to 2.6 km, it is determined that the vehicle starts the power conservation mode so that the power level of the vehicle's power battery is maintained within a preset power range.

[0102] In some embodiments, when the mileage is less than a preset mileage, it is determined that the vehicle does not start the power conservation mode.

[0103] For example, when the mileage of the vehicle is less than 2.6 km, it means that the vehicle is still in the testing state, so it is determined that the vehicle does not start the power conservation mode.

[0104] It should be understood that in order to avoid increasing the risk of vehicle equipment failure and increasing the difficulty of repairing buttons inside the cabin, the accelerator pedal and brake pedal are used to determine whether the vehicle is in power conservation mode, so as to avoid the vehicle being unable to charge during long-distance transportation, causing the vehicle's power battery to be in a low-power state for a long time.

[0105] The following describes the content of determining whether the vehicle turns on the power conservation mode based on the accelerator pedal parameters and / or brake pedal parameters.

[0106] In a possible implementation, an accelerator pedal parameter and / or a brake pedal parameter of the vehicle is obtained; based on the accelerator pedal parameter and / or the brake pedal parameter, it is determined whether the vehicle is in a power conservation mode.

[0107] The accelerator pedal parameters of the vehicle include the opening of the accelerator pedal. The brake pedal parameters of the vehicle include the opening of the brake pedal.

[0108] In this embodiment, only the accelerator pedal parameter and / or the brake pedal parameter are needed to determine whether the vehicle is in the power conservation mode, and no other modules need to be reintegrated in the cabin. In this case, not only the power battery of the vehicle is prevented from being depleted for a long time, but also the maintenance cost of the vehicle can be avoided.

[0109] In order to explain the above implementation in more detail, the above implementation is explained in several parts below.

[0110] The first part describes the contents of obtaining the vehicle's accelerator pedal parameters and / or brake pedal parameters.

[0111] In a possible implementation manner, the opening degree of the accelerator pedal of the vehicle is acquired based on an accelerator pedal sensor.

[0112] Among them, the opening of the accelerator pedal is used to monitor the accelerator pedal position.

[0113] In some embodiments, when the opening degree of the accelerator pedal is greater than or equal to a preset opening degree, it is determined that the accelerator pedal is depressed.

[0114] The preset opening is automatically determined by the vehicle controller or set by the technician according to the actual situation, and the present application embodiment does not limit this. For example, the preset opening can be 2%.

[0115] It should be understood that in actual applications, the opening of the accelerator pedal may vary in accuracy due to different vehicle models, and different vehicles may correspond to different preset openings.

[0116] In this implementation, the opening degree of the accelerator pedal is obtained based on the accelerator pedal sensor, so as to accurately determine whether the accelerator pedal of the vehicle is pressed.

[0117] In a possible implementation manner, the opening degree of the brake pedal of the vehicle is acquired based on a brake pedal sensor.

[0118] Among them, the opening of the brake pedal is used to monitor the brake pedal position.

[0119] It can be understood that the specific implementation of obtaining the opening of the vehicle's brake pedal can refer to the above-mentioned description of obtaining the opening of the vehicle's accelerator pedal, which will not be repeated here.

[0120] The second part explains the content of determining whether the vehicle turns on the power conservation mode based on the accelerator pedal parameters and / or brake pedal parameters.

[0121] It should be understood that if a button for controlling the power conservation mode is integrated into the vehicle's on-board equipment or a button for controlling the power conservation mode is set in the vehicle cabin, the risk of failure of the vehicle equipment will increase and the difficulty of repairing the buttons inside the cabin will increase. Therefore, in order to avoid the above situation, whether the vehicle has turned on the power conservation mode is determined based on the accelerator pedal parameters and / or brake pedal parameters.

[0122] In some embodiments, when the number of times the accelerator pedal is depressed in the accelerator pedal parameters is greater than or equal to a first preset number of times, it is determined that the vehicle is in the power conservation mode.

[0123] The first preset number of times is automatically determined by the vehicle controller, or is set by a technician according to actual conditions, and this embodiment of the present application does not limit this. For example, the first preset number of times may be four times.

[0124] For example, when the accelerator pedal is depressed four times or more, it is determined that the vehicle starts the power conservation mode so that the power level of the vehicle's power battery is maintained within a preset power range.

[0125] In some embodiments, when the number of times the brake pedal is depressed in the brake pedal parameters is greater than or equal to a second preset number of times, it is determined that the vehicle is in the power conservation mode.

[0126] The second preset number of times is automatically determined by the vehicle controller, or is set by a technician according to actual conditions, and this embodiment of the present application does not limit this. For example, the first preset number of times may be four times.

[0127] For example, when the brake pedal is depressed four times or more, it is determined that the vehicle starts the power conservation mode so that the power level of the vehicle's power battery is maintained within a preset power range.

[0128] In some embodiments, when the number of times the accelerator pedal is depressed is greater than or equal to a first preset number of times and the number of times the brake pedal is depressed is greater than or equal to a second preset number of times, it is determined that the vehicle is in power conservation mode.

[0129] In this embodiment, determining whether the vehicle turns on the power conservation mode is based on the accelerator pedal parameters and / or brake pedal parameters, which not only maintains the power level of the vehicle's power battery within a preset power range, but also reduces the complexity of maintaining the power conservation mode.

[0130] Optionally, whether the vehicle is in power conservation mode can also be determined through the following implementation.

[0131] In a possible implementation, a battery status parameter of a power battery of the vehicle is obtained; and based on the battery status parameter, it is determined whether to start the power conservation mode.

[0132] In some embodiments, battery status parameters of the vehicle are obtained based on a battery management system.

[0133] The battery management system is a system for managing and maintaining batteries. In some embodiments, the battery management system includes a power battery sensor. The battery status parameter includes the power of the power battery.

[0134] In some embodiments, the power level of a power battery in the vehicle is obtained based on a power battery sensor of the vehicle.

[0135] The power battery sensor is installed on the positive electrode or negative electrode of the power battery of the vehicle, and the power of the power battery is measured based on the power battery sensor.

[0136] It should be understood that during the transportation of the vehicle, the power battery has been replenishing the battery in real time. However, if the power of the power battery is less than or equal to 20%, the power battery cannot replenish the battery. In order to avoid the battery running out of power for too long, it is necessary to start the power conservation mode when the power of the power battery is too low.

[0137] In some embodiments, when the power level of the power battery is less than or equal to a preset power level, it is determined to start the power conservation mode.

[0138] The preset power is automatically determined by the vehicle controller or set by the technician according to the actual situation, which is not limited in the present embodiment. For example, the preset power can be 20%.

[0139] For example, when the power battery is at 20%, it is determined that the power battery is too low. To avoid long-term power shortage in the power battery, the vehicle is controlled to start the power conservation mode.

[0140] In this implementation mode, the battery status parameters of the vehicle's power battery are obtained; based on the battery status parameters, it is determined whether to turn on the power conservation mode, thereby avoiding long-term power loss of the power battery and replenishing the power battery in time.

[0141] Step 402 : When the vehicle is in the power conservation mode, determine whether the voltage state of the vehicle is a high voltage state.

[0142] The voltage state of the vehicle includes a high voltage state and a low voltage state.

[0143] When the vehicle is in a high-voltage state, it means that the power battery in the vehicle's high-voltage electrical system will generate high-voltage direct current, and the power battery will transmit the high-voltage direct current to various components on the vehicle that require high-voltage direct current through a high-voltage wiring harness.

[0144] The vehicle is in a low voltage state, which means that the battery in the vehicle's low voltage electrical system will release electrical energy to drive low voltage electrical devices. For example, low voltage electrical devices may include audio.

[0145] In a possible implementation manner, the voltage state of the vehicle is determined by a state signal of the vehicle or an electric motor; and it is determined whether the voltage state of the vehicle is a high voltage state.

[0146] The state signal includes a high voltage state signal or a low voltage state signal.

[0147] In some embodiments, if a high voltage state signal of the vehicle is obtained or the motor is started, it is determined that the voltage state of the vehicle is a high voltage state.

[0148] In some embodiments, if a low voltage state signal of the vehicle is acquired, it is determined that the voltage state of the vehicle is a low voltage state.

[0149] In this embodiment, the voltage state of the vehicle is determined by the vehicle status signal or the electric motor, that is, whether the power battery transmits high-voltage DC power to various components on the vehicle that require high-voltage DC power is determined, and whether the vehicle can operate normally is monitored in real time.

[0150] Optionally, after step 402, perform the following step 403 or step 404 according to actual conditions.

[0151] Step 403, when the voltage state of the vehicle is a high voltage state, determine that the target engine starting mode of the vehicle is a first engine starting mode, and the first engine starting mode is used to control the vehicle to start the engine through the electric motor corresponding to the power battery, so that the engine starts to supply power to the power battery.

[0152] It should be understood that since the vehicle cannot be recharged during transportation, the power battery of the vehicle needs to be recharged during transportation, so the power battery is always being consumed. To avoid the power battery being exhausted, the hybrid vehicle can supply power to the power battery through the engine.

[0153] The high voltage state of the vehicle indicates that the power battery of the vehicle generates high voltage direct current. The target engine start mode is used to control the engine start of the vehicle during the transportation of the vehicle so that the engine starts to supply power to the power battery.

[0154] Different voltage states correspond to different engine starting modes. That is, the high voltage state of the vehicle corresponds to the first engine starting mode. Figure 2 As shown, the first engine starting mode is to control the vehicle to transmit high-voltage direct current to the electric motor through the power battery, so that the electric motor starts the engine to supply power to the power battery.

[0155] It should be understood that when the vehicle's voltage state is in a high voltage state, the power battery of the vehicle's high voltage electrical system will generate high voltage direct current, and the electric motor can convert the electrical energy of the power battery into mechanical energy, thereby driving the rotation of the engine, that is, the power battery can drive the electric motor, and the electric motor can start the engine.

[0156] The following describes how to start the engine through the electric motor corresponding to the power battery so that the engine starts and supplies power to the power battery.

[0157] In a possible implementation, the vehicle is controlled to start the engine through the electric motor corresponding to the power battery, so that the engine starts to supply power to the power battery.

[0158] like Figure 2 As shown, when the vehicle is in power conservation mode, the electric motor converts the electrical energy of the power battery into mechanical energy to drive the engine gears to rotate, that is, the electric motor starts the engine.

[0159] In some embodiments, within a preset time, the gear of the motor drives the gear of the engine to rotate to start the engine. For example, the preset time is 2 seconds.

[0160] like Figure 2 As shown, since the engine is connected to the generator, after the engine is started, the engine can drive the generator, and the generator can convert the mechanical energy of the engine into electrical energy. The generator transmits the electrical energy to the power battery, and the power battery stores the electrical energy, thereby charging the power battery.

[0161] It should be understood that if the power battery continues to output electrical energy during the process of the engine charging the power battery, the charging amount of the power battery will decrease. To avoid the above situation, after the engine is started, the power battery is prohibited from outputting electrical energy.

[0162] In some embodiments, after the engine is started, the vehicle controller prohibits the power battery from outputting electrical energy.

[0163] In this implementation, the vehicle is controlled to start the engine through the motor corresponding to the power battery, so that the engine starts to supply power to the power battery. That is, when the power battery can also generate high-voltage direct current, in order to avoid excess energy loss, the engine is started by driving the motor with part of the high-voltage direct current. The engine converts the chemical energy of the fuel into electrical energy to replenish the power battery, thereby preventing the power battery from being depleted for a long time.

[0164] It should be understood that the gears on the motor drive the gears on the engine to rotate so that the engine can start. However, if the high-voltage DC power generated by the power battery is not enough to drive the motor, the gears on the motor cannot rotate, and the gears on the motor cannot drive the gears on the engine to rotate, and the engine cannot start. In this case, in order to replenish the power battery in time, it is necessary to determine whether the engine has started successfully.

[0165] Optionally, after executing the above step 403, the following steps may also be executed.

[0166] In a possible implementation, it is determined whether the engine is started successfully; if the engine fails to start, the target engine starting mode of the vehicle is adjusted from the first engine starting mode to the second engine starting mode.

[0167] Among them, the second engine starting mode is used to control the vehicle to start the engine through the starter corresponding to the battery, so that the engine starts to supply power to the power battery.

[0168] In some embodiments, the engine speed is acquired based on an engine sensor; when the engine speed is less than or equal to a preset speed, it is determined that the engine start has failed.

[0169] The preset speed is automatically determined by the vehicle controller or set by the technician according to the actual situation, which is not limited in the present embodiment. For example, the preset speed may be 0 revolutions per minute.

[0170] It should be understood that the failure to start the vehicle's engine means that the engine cannot be started based on the electric motor corresponding to the power battery. In this case, in order to replenish the power battery with electric energy in time, the vehicle's target engine starting mode is adjusted from the first engine starting mode to the second engine starting mode to start the engine.

[0171] In this embodiment, even if the engine cannot be started based on the electric motor corresponding to the power battery, the engine can be started based on the starter corresponding to the battery, thereby replenishing electrical energy to the power battery in time.

[0172] Optionally, after step 403, directly execute the following steps 405 and 406 according to actual conditions.

[0173] Step 404, when the voltage state of the vehicle is in a low voltage state, determine that the target engine starting mode of the vehicle is a second engine starting mode, and the second engine starting mode is used to control the vehicle to start the engine through the starter corresponding to the battery, so that the engine starts to supply power to the power battery.

[0174] It should be understood that during the transportation of the vehicle, the power battery can replenish the battery. Therefore, the battery is always fully charged. When the voltage of the vehicle is low, the power battery of the vehicle cannot drive the motor to start the engine. In order to replenish the power battery in time, the engine is started based on the starter corresponding to the battery.

[0175] Among them, the starter corresponding to the battery is used to start the engine. Figure 2 As shown, the second engine starting mode is a starting mode in which the vehicle is controlled to transmit low-voltage direct current to the starter through the battery, so that the starter starts the engine to supply power to the power battery.

[0176] The following is a detailed description of the contents of starting the engine by using the starter corresponding to the battery so that the engine starts to supply power to the power battery.

[0177] In a possible implementation, the vehicle is controlled to start the engine through a starter corresponding to the battery, so that the engine starts to supply power to the power battery.

[0178] In some embodiments, Figure 2 As shown, the battery is connected to the starter, and the battery provides electrical energy to the starter. When the vehicle is in power conservation mode and the voltage state of the vehicle is low, the vehicle can only be powered by the battery, and the starter converts the battery's electrical energy into mechanical energy to drive the engine's gears to rotate, that is, the starter starts the engine.

[0179] In some embodiments, Figure 2 As shown, after the engine is started, power is supplied to the power battery based on the generator.

[0180] It is understandable that after the engine is started, the specific implementation of supplying power to the power battery based on the generator can refer to the relevant description of the aforementioned step 403, which will not be repeated here.

[0181] In this implementation, the vehicle is controlled to start the engine through the starter corresponding to the battery, so that the engine starts to supply power to the power battery. That is, when the power battery cannot generate high-voltage direct current, the starter is driven based on the electrical energy in the battery to start the engine. The engine converts the chemical energy of the fuel into electrical energy to replenish the power battery, thereby preventing the power battery from being depleted for a long time.

[0182] Step 405 , controlling the vehicle to start the engine in a target engine starting mode to preserve the power battery.

[0183] It should be understood that different voltage states correspond to different target engine starting methods. When the power battery of the vehicle is low in power, the vehicle is controlled to start the engine in the target engine starting method to preserve the power battery.

[0184] In some embodiments, when the target engine starting mode of the vehicle is the first engine starting mode, the electric motor corresponding to the power battery of the vehicle is controlled to start the engine, so that the engine starts to supply power to the power battery.

[0185] It should be understood that when the vehicle's voltage is in a high-voltage state, the power battery can generate high-voltage direct current. Therefore, the engine is started by driving the electric motor corresponding to the power battery based on the excess electric energy to preserve the power battery, thereby avoiding the power battery from being depleted for a long time during transportation, causing irreversible damage to the power battery.

[0186] In some embodiments, when the target engine starting mode of the vehicle is the second engine starting mode, the starter corresponding to the battery of the vehicle is controlled to start the engine, so that the engine starts to supply power to the power battery.

[0187] It should be understood that when the vehicle's voltage is in a low voltage state, the power battery cannot generate high-voltage direct current. Therefore, the starter is driven by the battery's electric energy to start the engine to preserve the power battery, thereby avoiding long-term power loss of the power battery during transportation, and thus avoiding irreversible damage to the power battery.

[0188] In some embodiments, after the power battery is charged, electric energy is stored in the power battery. In this case, the power battery is used to transmit electric energy to the storage battery to avoid the storage battery from being depleted for a long time during transportation, thereby avoiding irreversible damage to the storage battery.

[0189] Step 406, controlling the vehicle to turn off the power conservation mode.

[0190] It should be understood that during long-distance transportation, the vehicle's power battery cannot be charged in time, so it is necessary to use the engine to maintain the power of the power battery. However, if the vehicle completes the long-distance transportation, the vehicle's power battery can be charged in time. In this case, if the power battery is still replenished with power through the engine, the engine will always be in working state, which may easily cause damage to the engine and waste fuel in the vehicle. To avoid the above problems, the vehicle is controlled to turn off the power conservation mode.

[0191] Among them, the vehicle shuts down the power conservation mode, which means that the vehicle's engine will no longer replenish the power battery after it is started. In this case, if the vehicle's engine is started, the engine converts the chemical energy of the fuel into kinetic energy to drive the vehicle.

[0192] In a possible implementation, the vehicle is controlled to turn off the power conservation mode based on the accelerator pedal parameter and / or the brake pedal parameter.

[0193] The accelerator pedal parameters of the vehicle include the opening of the accelerator pedal. The brake pedal parameters of the vehicle include the opening of the brake pedal.

[0194] In this implementation, the vehicle is controlled to shut down the power conservation mode based on the accelerator pedal parameters and / or brake pedal parameters, which is not only easy to operate but also prevents the engine in the vehicle from being started for a long time, thereby avoiding damage to the engine.

[0195] The following describes the contents of controlling the vehicle to turn off the power conservation mode based on the accelerator pedal parameters and / or brake pedal parameters.

[0196] In some embodiments, when the number of times the accelerator pedal is depressed in the accelerator pedal parameters is greater than or equal to a third preset number of times, the vehicle is controlled to turn off the power conservation mode.

[0197] The third preset number is automatically determined by the vehicle controller or set by a technician according to actual conditions, and the present application embodiment does not limit this. For example, the third preset number can be three times.

[0198] For example, when the accelerator pedal is depressed three times or more, the vehicle is controlled to turn off the power conservation mode to reduce fuel consumption in the vehicle.

[0199] In some embodiments, when the number of times the brake pedal is depressed in the brake pedal parameters is greater than or equal to a fourth preset number of times, the vehicle is controlled to turn off the power conservation mode.

[0200] The fourth preset number is automatically determined by the vehicle controller or set by a technician according to actual conditions, and the present application embodiment does not limit this. For example, the fourth preset number can be three times.

[0201] For example, when the brake pedal is depressed three times or more, the vehicle is controlled to turn off the power conservation mode to reduce fuel consumption in the vehicle.

[0202] In some embodiments, when the accelerator pedal is depressed a number of times greater than or equal to a third preset number of times and when the brake pedal is depressed a number of times greater than or equal to a fourth preset number of times, the vehicle is controlled to turn off the power conservation mode to reduce fuel consumption in the vehicle.

[0203] In this embodiment, the vehicle is controlled to turn off the power conservation mode based on the accelerator pedal parameter and / or the brake pedal parameter, that is, the engine rotation is stopped, thereby reducing the engine oil consumption and can reduce the fuel consumption in the vehicle.

[0204] It should be understood that in actual applications, after the vehicle is transported, the transporter may forget to step on the brake pedal or the accelerator pedal to exit the power conservation mode. In this case, in order to prevent the engine from being in operation all the time, the vehicle is controlled to turn off the power conservation mode based on the vehicle's fuel tank parameters.

[0205] In a possible implementation, the vehicle is controlled to turn off the power conservation mode based on a fuel tank parameter of the vehicle.

[0206] The fuel tank parameters are used to describe the fuel tank status, including the fuel volume of the vehicle and the number of times the fuel tank door of the vehicle is opened. The fuel tank parameters are used to describe the fuel volume in the fuel tank.

[0207] It should be understood that during the transportation of the vehicle, the amount of fuel in the vehicle cannot be replenished in time, so if the amount of fuel in the vehicle increases and the fuel tank door of the vehicle is opened, it means that the vehicle has ended transportation.

[0208] In this case, controlling the vehicle to shut down the power conservation mode based on the vehicle's fuel tank parameters can not only shut down the power conservation mode in time and reduce fuel consumption in the vehicle, but also is easy to operate.

[0209] The following is an explanation of the contents of controlling the vehicle to shut down the power conservation mode based on the vehicle's fuel tank parameters.

[0210] In one possible implementation, a fuel tank parameter of the vehicle is obtained; based on the fuel tank parameter of the vehicle, it is determined whether the vehicle meets a preset condition for shutting down the power conservation mode; if the vehicle meets the preset condition for shutting down the power conservation mode, the vehicle is controlled to shut down the power conservation mode; if the vehicle does not meet the preset condition for shutting down the power conservation mode, the vehicle is controlled to maintain in the power conservation mode.

[0211] The fuel tank parameters of the vehicle include the number of times the fuel tank door of the vehicle is opened and the fuel volume of the vehicle.

[0212] In this embodiment, after the vehicle completes transportation, even if the transporter forgets to step on the brake pedal or the accelerator pedal, it is still possible to determine whether the vehicle has exited the power conservation mode based on the vehicle's fuel tank parameters to avoid fuel loss of the vehicle.

[0213] In order to explain the above implementation in more detail, the above implementation is explained in several parts below.

[0214] The first part explains in detail the contents of obtaining the vehicle's fuel tank parameters.

[0215] In a possible implementation, the fuel amount of the vehicle and the number of times the fuel tank door of the vehicle is opened are acquired based on a fuel tank sensor.

[0216] In some embodiments, if the fuel tank sensor is a resistive sensor, the rise and fall of the fuel level in the fuel tank can change the resistance of the resistive sensor to obtain the fuel level of the vehicle.

[0217] The resistive sensor is connected to a float that floats in the tank and moves up and down as the amount of fuel increases or decreases. The movement of the float drives the slider of the variable resistor of the resistive sensor through a mechanical linkage or direct physical contact, thereby changing the resistance value. This change in resistance value is then detected and converted into an electrical signal, which is ultimately displayed as a fuel level reading.

[0218] In some embodiments, if the fuel tank sensor is a switch sensor, when the fuel tank door is opened, the switch sensor can trigger an electrical signal to obtain the number of times the fuel tank door of the vehicle is opened.

[0219] In this implementation, the vehicle fuel tank parameters are obtained based on the fuel tank sensor, so that the vehicle's fuel amount and the number of times the vehicle's fuel tank door is opened can be accurately monitored.

[0220] The second part provides a detailed explanation of the content of determining whether the vehicle meets the preset conditions for shutting down the power conservation mode based on the vehicle's fuel tank parameters.

[0221] In some embodiments, it is determined whether the number of times the vehicle's fuel tank door is opened is greater than or equal to a fifth preset number of times; if the number of times the vehicle's fuel tank door is opened is greater than or equal to the fifth preset number of times, it is determined whether the vehicle's fuel level is greater than or equal to a preset fuel level; if the vehicle's fuel level is greater than or equal to a preset fuel level, it is determined that the vehicle meets the preset conditions for shutting down the power conservation mode.

[0222] The fifth preset number is automatically determined by the vehicle controller or set by a technician according to actual conditions, and the present application embodiment does not limit this. For example, the fifth preset number may be 1 time.

[0223] The preset fuel quantity is automatically determined by the vehicle controller, or is set by the technician according to the actual situation, and the present application embodiment does not limit this. For example, the preset fuel quantity can be one quarter of the fuel tank capacity.

[0224] For example, when the fuel tank door of the vehicle is opened once, it is determined that the fuel amount of the vehicle has increased to one quarter of the fuel tank capacity, and therefore it is determined that the vehicle meets the preset conditions for closing the power conservation mode.

[0225] In this embodiment, the vehicle cannot be refueled during transportation. If the fuel tank door of the vehicle is opened and the fuel level of the vehicle increases, it can be determined that the vehicle has been refueled. In this case, it is determined that the vehicle meets the preset conditions for shutting down the power conservation mode, so the vehicle is controlled to shut down the power conservation mode to avoid fuel loss of the vehicle.

[0226] An embodiment of the present application provides a method for controlling a vehicle, which can determine whether the vehicle is in a power conservation mode based on accelerator pedal parameters and / or brake pedal parameters, and when the vehicle is in the power conservation mode, determine whether the voltage state of the vehicle is a high voltage state. That is, different engine starting methods are determined based on different voltage states of the vehicle to start the engine to supply power to the power battery. In this case, it is possible to cope with different voltage states in the vehicle to avoid the inability to start the engine when the vehicle is in a low voltage state, thereby avoiding long-term power loss of the power battery. After the power battery is conserved and the vehicle ends the transportation process, the vehicle is controlled to turn off the power conservation mode to avoid the engine starting for a long time, causing damage to the engine or waste of fuel in the vehicle.
