Description

Technical Field

[0001] This application belongs to the field of vehicles, and particularly relates to a vehicle and a method for controlling a vehicle. Background Technology

[0002] Hybrid vehicles in related technologies are generally two-wheel drive or four-wheel drive vehicles. Two-wheel drive vehicles cannot provide the horsepower of four-wheel drive, while four-wheel drive vehicles cannot achieve the fuel economy of two-wheel drive. Moreover, the driving mode can only be range-extended or plug-in hybrid, which is relatively simple and makes it difficult to select the appropriate driving mode according to different driving environments, thus affecting the user experience. Summary of the Invention

[0003] This application aims to address at least one of the technical problems existing in the related art. To this end, this application proposes a vehicle and a vehicle control method that allows the vehicle to flexibly select or switch between four different driving modes—pure fuel drive, range-extended drive, economy drive, and four-wheel drive—based on user needs or preferences. This improves the selectivity of vehicle driving modes and the flexibility of driving mode switching, thereby enhancing the user's driving experience.

[0004] In a first aspect, this application provides a vehicle comprising:

[0005] A plurality of first wheels disposed on a first axle and a plurality of second wheels disposed on a second axle;

The engine, electric motor, and power supply device are configured to enter corresponding working states based on the vehicle's driving mode. This allows for combinations of different working states of the engine, electric motor, and power supply device, enabling the vehicle to flexibly select or switch between multiple driving modes based on user needs or preferences in different driving environments, considering factors such as overall economy, low energy consumption, range, and speed, thereby improving the user's driving experience.

[0014] When the driving mode is the fourth mode, the engine, the electric motor, and the power supply device enter the corresponding working state based on the power value of the energy storage module.

[0015] According to one embodiment of this application, when the driving mode is the second mode and the power value of the energy storage module is greater than a first threshold, the generator does not work;

[0016] When the driving mode is the second mode and the energy storage module's charge value is less than or equal to a first threshold, the generator rotates under the drive of the engine to generate electricity for the energy storage module.

[0017] According to one embodiment of this application, when the driving mode is the fourth mode, the engine, the electric motor, and the power supply device enter a corresponding operating state based on the energy storage module's charge value, including:

[0022] When the energy storage module's charge level is less than or equal to a second threshold and the vehicle's speed is greater than a third threshold, the engine operates to drive the first axle to rotate.

[0023] According to one embodiment of this application, the engine is configured such that, when the operation of the electric motor switches to the operation of the engine, or when the electric motor and the engine operate simultaneously, the rotational speed of the engine matches the rotational speed of the electric motor.

[0024] According to one embodiment of this application, it also includes:

[0025] A first bevel gear, which is connected to the engine;

[0026] A first clutch, wherein a first end of the first clutch is connected to the first bevel gear, and a second end of the first clutch is connected to the first axle;

[0027] The second bevel gear meshes with the first bevel gear;

[0028] The second clutch has a first end connected to the second bevel gear and a second end connected to the generator.

[0029] The third clutch has a first end connected to the electric motor and a second end connected to the second axle.

[0030] Secondly, this application provides a vehicle control method, the method comprising:

[0031] The vehicle's driving mode is obtained, including a first mode, a second mode, a third mode, and a fourth mode;

[0032] Based on the driving mode, the operating states of the engine, electric motor, and power supply device are controlled; wherein, the engine is connected to the first axle of the vehicle, and the electric motor is connected to the second axle of the vehicle; the power supply device includes an energy storage module and a generator connected to the energy storage module, the generator is drivenly connected to the engine, and the energy storage module is connected to the electric motor.

[0033] According to the vehicle control method of this application, by acquiring the vehicle's driving mode, which includes a first mode, a second mode, a third mode, and a fourth mode, the operating states of the engine, electric motor, and power supply device are controlled based on the acquired driving mode. This allows for the combination of different operating states of the engine, electric motor, and power supply device, enabling the vehicle to flexibly select or switch between multiple driving modes based on user needs or preferences in different driving environments, considering factors such as overall economy, low energy consumption, range, and speed, thereby improving the user's driving experience.

[0034] According to one embodiment of this application, controlling the operating state of the engine, electric motor, and power supply device based on the driving mode includes:

[0035] When the driving mode is the first mode, control the engine to operate;

[0036] When the driving mode is the second mode, the electric motor is controlled to work, and the working state of the engine is controlled based on the power value of the energy storage module;

[0037] When the driving mode is the third mode, control the engine and the electric motor to operate;

[0038] When the driving mode is the fourth mode, the operating status of the engine, electric motor and power supply device is controlled based on the power value of the energy storage module and the vehicle speed.

[0039] Thirdly, this application provides a non-transitory computer-readable storage medium having a computer program stored thereon, which, when executed by a processor, implements the vehicle control method as described in the first aspect above.

[0040] Fourthly, this application provides a computer program product, including a computer program that, when executed by a processor, implements the vehicle control method as described in the first aspect above.

[0041] The above-described one or more technical solutions in the embodiments of this application have at least one of the following technical effects:

[0042] By configuring a vehicle with multiple first wheels on a first axle, multiple second wheels on a second axle, an engine connected to the first axle, an electric motor connected to the second axle, and a power supply device including an energy storage module and a generator connected to the energy storage module, wherein the generator in the power supply device is connected to the engine, and the energy storage module in the power supply device is connected to the electric motor, the engine, electric motor, and power supply device are configured to enter corresponding working states based on the vehicle's driving mode, the vehicle can realize combinations of different working states based on the engine, electric motor, and power supply device. This allows the vehicle to flexibly select or switch multiple driving modes based on user needs or preferences in different driving environments, considering factors such as overall economy, low energy consumption, range, and speed, thereby improving the user's driving experience.

[0043] Furthermore, by setting the driving mode to the second mode and ensuring that the generator does not operate when the energy storage module's charge level is greater than the first threshold, while allowing the generator to rotate under the engine's drive to generate electricity for the energy storage module when the energy storage module's charge level is less than or equal to the first threshold, energy source management can be achieved for the vehicle's range-extending mode driving in the second mode while the electric motor is driving, thus extending the overall driving range in the second mode.

[0044] Furthermore, by having the electric motor operate to drive the second axle to rotate when the energy storage module's charge level is greater than the second threshold, and by having the engine and electric motor enter corresponding operating states based on the vehicle's speed when the energy storage module's charge level is less than or equal to the second threshold, it is possible to prioritize electric drive, reduce energy consumption by driving purely on electric power when the battery is fully charged, and then, when the battery is insufficient, allow the engine and electric motor to enter a low-cost driving state based on the vehicle's speed. This allows for both ensuring a good user experience and optimizing the economic cost of vehicle operation.

[0045] Furthermore, when the energy storage module's charge level is less than or equal to a second threshold and the vehicle speed is less than or equal to a third threshold, the electric motor operates to drive the second axle to rotate, and the engine drives the generator to rotate to generate electricity for the energy storage module based on maximum efficiency. When the vehicle speed is greater than the third threshold, the engine operates to drive the first axle to rotate, which can improve the engine's fuel economy when the energy storage module's charge level is insufficient.

Furthermore, in the specification and claims, "and / or" indicates at least one of the connected objects, and the character " / " generally indicates that the preceding and following objects are in an "or" relationship.

[0059] The following is in conjunction with the appendix Figure 1 and attached Figure 2 The vehicle provided in the embodiments of this application will be described.

[0060] like Figure 1 As shown, this application provides a vehicle in its embodiments.

[0061] In this embodiment, the vehicle includes: a plurality of first wheels 112 disposed on a first axle 101, a plurality of second wheels 113 disposed on a second axle 102, an engine 103, an electric motor 104, and a power supply device.

[0062] The first axle 101 can be either the front axle or the rear axle of the vehicle.

[0063] The second axle 102 can be another axle that is not the first axle 101.

[0064] For example, if the first axle 101 is the front axle, the second axle 102 is the rear axle, and vice versa.

[0065] The engine 103 is connected to the first axle 101.

[0066] The electric motor 104 is connected to the second axle 102.

[0067] In actual operation, the engine 103 can drive the first axle 101 to rotate using fuel; the electric motor 104 can drive the second axle 102 to rotate using electrical energy.

[0068] The power supply device includes an energy storage module 106 and a generator 105 connected to the energy storage module 106. The generator 105 is connected to the engine 103 via a drive, and the energy storage module 106 is connected to the motor 104.

[0069] The energy storage module 106 may include one or more battery clusters for storing electrical energy.

[0070] In some embodiments, the energy storage module 106 is connected to the generator 105 and the motor 104 via wiring harness 114.

[0071] In actual operation, the engine 103 can drive the generator 105 to rotate using fuel, thereby enabling the generator 105 to generate electricity to the energy storage module 106. The electrical energy of the energy storage module 106 can be used by the electric motor 104 to drive the second axle 102.

[0072] The energy source for the energy storage module 106 can be generated by the generator 105 or charged by an external power source.

[0073] The engine 103, electric motor 104, and power supply device are configured to enter corresponding operating states based on the vehicle's driving mode.

[0074] Driving modes can include mode 1, mode 2, mode 3, and mode 4.

[0075] The first mode is pure fuel mode, the second mode is range-extending mode, and the fourth mode is economy-driven mode.

[0076] The first, second, and fourth modes are all two-wheel drive modes, that is, the first axle 101 drives or the second axle 102 drives.

[0077] The third mode is the four-wheel drive mode, which is the mode in which the first axle 101 and the second axle 102 drive together.

[0078] The work status can be either working or not working.

[0079] In actual operation, the working states of the engine 103, electric motor 104 and power supply device are different under different driving modes. It can be understood that different combinations of the working states of the engine 103, electric motor 104 and power supply device can realize a variety of different driving modes, namely the first mode, the second mode, the third mode and the fourth mode.

[0080] In some embodiments, when the driving mode is the first mode, the engine 103 operates to drive the first axle 101 to rotate;

[0081] When the driving mode is in the second mode, the electric motor 104 operates to drive the second axle 102 to rotate;

[0082] When the driving mode is the third mode, the engine 103 operates to drive the first axle 101 to rotate, and the electric motor 104 operates to drive the second axle 102 to rotate.

[0083] When the driving mode is in the fourth mode, the engine 103, electric motor 104 and power supply device are controlled to enter the corresponding working state based on the power value of the energy storage module 106.

[0084] In this embodiment, it is understood that in the first mode, the engine 103 operates to drive the first axle 101 to rotate, during which the electric motor 104 and the power supply device do not operate, thereby enabling pure fuel two-wheel drive driving and providing users with the driving experience of a pure fuel vehicle.

[0085] In the second mode, the electric motor 104 operates to drive the second axle 102 to rotate. During this period, it can be determined whether the engine 103 needs to operate to drive the generator 105 to generate electricity to the energy storage module 106 based on the amount of electricity in the energy storage module 106, thereby realizing range-extended mode drive.

[0086] In the third mode, the engine 103 operates to drive the first axle 101 to rotate, while the electric motor 104 operates to drive the second axle 102 to rotate, thereby achieving a higher horsepower four-wheel drive.

[0087] In actual operation, in the third mode, when the energy storage module 106 has sufficient power, the generator 103 operates to drive the first axle 101 to rotate, and at the same time, the energy storage module 106 supplies power to the motor 104 so that the motor 104 operates to drive the second axle 102 to rotate. When the energy storage module 106 has insufficient power, the engine 103 operates to drive the first axle 101, and at the same time, it can drive the generator 105 to generate electricity to power the energy storage module 106. The energy storage module 106 supplies power to the motor 104 so that the motor 104 drives the second axle 102 to rotate.

[0088] It is understandable that the engine 103 will drive the generator 105 to generate electricity only when the energy storage module 106 is insufficient. In actual operation, when the energy storage module 106 is charged by an external power source and has sufficient power, the energy stored in the energy storage module 106 should be used first to supply power to the motor 104; that is, the external power source should be given priority, and the generator 103 should be used secondarily to reduce carbon emissions. The source of power for the energy storage module 106 in other modes is the same, and will not be elaborated on further.

[0089] In the fourth mode, the engine 103, the electric motor 104, and the power supply device can enter the corresponding working state based on the power value of the energy storage module 106 with the goal of low economic cost.

[0090] For example, in some embodiments, the economic cost of the vehicle under different operating states of the engine 103, electric motor 104 and power supply device can be simulated in advance, and the operating state of the engine 103, electric motor 104 and power supply device corresponding to the lowest economic cost is determined as the operating state of the engine 103, electric motor 104 and power supply device in the fourth mode. When the vehicle is driving in the fourth mode, the engine 103, electric motor 104 and power supply device enter the corresponding operating state to achieve economic driving.

[0091] According to the vehicle provided in the embodiments of this application, by combining different working states of the engine 103, the electric motor 104 and the power supply device, four vehicle driving modes, including pure fuel drive, range-extended drive, economy drive and four-wheel drive, can be realized, including a first mode, a second mode, a third mode and a fourth mode, thereby improving the flexibility and diversity of vehicle driving mode and enhancing the user experience.

[0092] It is understandable that by changing the operating state of the engine 103, the electric motor 104, and the power supply device, the driving mode can be changed. For example, the operating state of the engine 103, the electric motor 104, and the power supply device can be changed to switch the vehicle from two-wheel drive corresponding to the first mode, the second mode, and the fourth mode to four-wheel drive corresponding to the third mode. Of course, conversely, four-wheel drive can also be switched to two-wheel drive.

[0093] During vehicle operation, users can flexibly switch driving modes based on actual conditions or preferences. In some accident scenarios, such as when the vehicle is in the first, second, or fourth mode but the drive wheels are stuck on a soft surface, the vehicle can switch from two-wheel drive (corresponding to the first, second, or fourth mode) to four-wheel drive (corresponding to the third mode), allowing the vehicle to get out of trouble on its own without waiting for rescue.

[0094] During the research and development process, the inventors discovered that in related technologies, hybrid vehicles are generally two-wheel drive or four-wheel drive vehicles. Two-wheel drive vehicles cannot provide the high horsepower of four-wheel drive, while four-wheel drive vehicles cannot achieve the fuel economy of two-wheel drive. Furthermore, their driving modes are limited to range-extended or plug-in hybrid, failing to provide the driving experience of a pure gasoline vehicle. Additionally, when one drive wheel of a two-wheel drive vehicle becomes stuck on a soft surface, the vehicle cannot extricate itself.

[0095] In this application, a vehicle is described, comprising a plurality of first wheels 112 disposed on a first axle 101, a plurality of second wheels 113 disposed on a second axle 102, an engine 103 connected to the first axle 101, an electric motor 104 connected to the second axle 102, and a power supply device including an energy storage module 106 and a generator 105 connected to the energy storage module 106. The generator 105 in the power supply device is driveably connected to the engine 103, and the energy storage module 106 in the power supply device is connected to the electric motor 104. The engine 103, electric motor 104, and power supply device are configured to, based on the vehicle... The vehicle enters the corresponding working state based on the different combinations of the working states of the engine 103, electric motor 104 and power supply device. This allows the vehicle to flexibly select from four different driving modes: pure fuel drive, range-extended drive, economy drive, and four-wheel drive. During driving, the vehicle can flexibly switch between driving modes based on scenario needs or user preferences. For example, if a two-wheel drive vehicle gets stuck on a soft surface, it can switch from two-wheel drive to four-wheel drive to allow the vehicle to get out of trouble on its own. This improves the selectivity of the vehicle's driving modes and the flexibility of driving mode switching, thereby enhancing the user's driving experience.

[0096] The vehicle provided according to the embodiments of this application includes a plurality of first wheels 112 disposed on a first axle 101, a plurality of second wheels 113 disposed on a second axle 102, an engine 103 connected to the first axle 101, an electric motor 104 connected to the second axle 102, and a power supply device including an energy storage module 106 and a generator 105 connected to the energy storage module 106. The generator 105 in the power supply device is connected to the engine 103, and the energy storage module 106 in the power supply device is connected to the electric motor 104. The engine 103, the electric motor 104, and the power supply device are configured to enter corresponding working states based on the vehicle's driving mode. This allows for combinations of different working states of the engine 103, the electric motor 104, and the power supply device, enabling the vehicle to flexibly select or switch between multiple driving modes based on user needs or preferences in different driving environments, considering factors such as overall economy, low energy consumption, range, and speed, thereby improving the user's driving experience.

[0097] In some embodiments, when the driving mode is the second mode and the energy storage module 106 has a power value greater than a first threshold, the generator 105 does not work.

[0098] When the driving mode is the second mode and the energy storage module 106 has a power value less than or equal to the first threshold, the generator 105 rotates under the drive of the engine 103 to generate electricity for the energy storage module 106.

[0099] In this embodiment, the first threshold is a safe threshold for the power value of the energy storage module 106.

[0100] In actual operation, when the energy value of the energy storage module 106 is higher than the first threshold, the energy storage module 106 can safely generate electricity to the motor 104. When the energy value of the energy storage module 106 is lower than the first threshold, the energy storage module 106 may not be able to generate electricity to the motor 104 normally.

[0101] In some embodiments, the first threshold can be set based on engineering experience. For example, the amount of electricity that the energy storage module 106 can normally generate to the motor 104 can be collected in advance, and the minimum value of the amount of electricity that can normally generate to the motor 104 can be determined as the first threshold. Of course, in other embodiments, the first threshold can also be obtained based on other methods, which are not limited here.

[0102] Understandably, when the driving mode is the second mode, i.e., the range-extended driving mode, the relationship between the power value of the energy storage module 106 and the first threshold can be determined in real time during actual driving. When the power value of the energy storage module 106 is greater than the first threshold, i.e., when the energy storage module 106 has sufficient power, the energy storage module 106 generates electricity to the motor 104, so that the motor 104 works and drives the second axle 102 to rotate, while the generator 105 does not work. When the power value of the energy storage module 106 is less than or equal to the first threshold, i.e., when the energy storage module 106 is depleted, the engine 103 works, but does not drive the first axle 101 to rotate. Instead, it drives the generator 105 to rotate to generate electricity for the energy storage module 106, thereby realizing the range-extended driving mode.

[0103] According to the vehicle provided in the embodiments of this application, when the driving mode is the second mode and the power value of the energy storage module 106 is greater than the first threshold, the generator 105 does not work, while when the power value of the energy storage module 106 is less than or equal to the first threshold, the generator 105 rotates under the drive of the engine 103 to generate electricity for the energy storage module 106. This can realize the energy source management of the vehicle in the second mode driven by the electric motor 104, thereby extending the comprehensive driving range in the second mode.

[0104] In some embodiments, when the driving mode is the fourth mode, based on the power value of the energy storage module 106, the vehicle's driving mode is controlled to enter the corresponding working state, including:

[0105] When the energy storage module 106 has a power value greater than the second threshold, the motor 104 operates to drive the second axle 102 to rotate.

[0106] When the energy storage module 106 has a charge value less than or equal to the second threshold, the engine 103 and the electric motor 104 enter the corresponding working state based on the vehicle speed.

[0107] In this embodiment, the second threshold is a threshold used to determine whether the energy storage module 106 has sufficient power. It can be set by the user and can be determined based on actual needs. This application does not limit it here. In some embodiments, the second threshold can be set to be the same as the first threshold.

[0108] Understandably, when the vehicle is in the fourth driving mode, it can first be determined whether the power value of the energy storage module 106 is greater than the second threshold. If the power value of the energy storage module 106 is greater than the second threshold, the electric motor 104 is generated based on the electrical energy stored in the energy storage module 106, so that the electric motor 104 works to drive the second axle 102 to rotate. If the power value of the energy storage module 106 is less than or equal to the second threshold, the working status of the engine 103 and the electric motor 104 can be determined based on the vehicle speed, with the goal of low economic cost, so as to realize the economic driving mode corresponding to the fourth mode.

[0109] In actual implementation, the process of determining the working status of engine 103 and electric motor 104 based on vehicle speed and with the goal of low economic cost can be similar to the process of determining the working status of engine 103, electric motor 104 and power supply device under low economic cost conditions in the above embodiment, and will not be described in detail here.

[0110] According to the vehicle provided in the embodiments of this application, when the power value of the energy storage module 106 is greater than the second threshold, the electric motor 104 operates to drive the second axle 102 to rotate, and when the power value of the energy storage module 106 is less than or equal to the second threshold, the engine 103 and the electric motor 104 enter the corresponding working state based on the vehicle speed. This can achieve priority given to electric drive, pure electric drive to reduce energy consumption when the battery is sufficient, and when the power is insufficient, the engine 103 and the electric motor 104 enter the driving state with low economic cost based on the vehicle speed. This can achieve both ensuring the user experience and taking into account the economic cost of vehicle operation.

[0111] In some embodiments, when the energy storage module 106 has a charge value less than or equal to a second threshold, the engine 103 and the electric motor 104 enter a corresponding operating state based on the vehicle speed, including:

[0112] When the energy storage module 106 has a charge value less than or equal to the second threshold and the vehicle speed is less than or equal to the third threshold, the electric motor 104 operates to drive the second axle 102 to rotate, and the engine 103 drives the generator 105 to rotate based on maximum efficiency to generate electricity for the energy storage module 106.

[0113] When the energy storage module 106 has a charge value less than or equal to the second threshold and the vehicle speed is greater than the third threshold, the engine 103 operates to drive the first axle 101 to rotate.

[0114] In this embodiment, the third threshold is used to determine whether the vehicle speed is in the high-speed driving range or the low-speed driving range.

[0115] In actual operation, when the vehicle speed is less than or equal to the third threshold, the vehicle speed is in the low-speed driving range; when the vehicle speed is greater than the third threshold, the vehicle speed is in the high-speed driving range.

[0116] Understandably, when the energy storage module 106 is low in power and the vehicle is traveling at low speed, the engine 103 can drive the generator 105 to generate electricity for the energy storage module 106 based on maximum efficiency. The energy storage module 106 then generates electricity for the electric motor 104, which in turn drives the second axle 102 to rotate. Here, maximum efficiency refers to maximizing the conversion of fuel into electrical energy. When the energy storage module 106 is low in power and the vehicle is traveling at high speed, the engine 103 can be switched to directly drive the first axle 101 to rotate.

[0117] It should be noted that the engine 103 drives the generator 105 to rotate based on maximum efficiency to generate electricity for the energy storage module 106, which is more economical than directly driving the first axle 101 to rotate.

[0118] Understandably, the third threshold can be determined based on engineering experience and with the goal of low economic cost. For example, at different vehicle speeds, the economic costs of the two engine 103 operating modes can be compared. The engine 103 drives the generator 105 to generate electricity for the energy storage module 106 and the electric motor 104 drives the second axle 102 to rotate, while the engine 103 directly drives the first axle 101 to rotate. Based on the change of economic cost of each engine 103 operating mode with vehicle speed, the third threshold with lower economic cost can be determined.

[0119] According to the vehicle provided in the embodiments of this application, when the power value of the energy storage module 106 is less than or equal to a second threshold and the vehicle speed is less than or equal to a third threshold, the electric motor 104 operates to drive the second axle 102 to rotate, and the engine 103 drives the generator 105 to rotate to generate electricity for the energy storage module 106 based on maximum efficiency. When the vehicle speed is greater than the third threshold, the engine 103 operates to drive the first axle 101 to rotate. This can improve the fuel economy of the engine 103 when the power of the energy storage module 106 is insufficient.

[0120] In some embodiments, the engine 103 is configured such that when the operation of the electric motor 104 switches to the operation of the engine 103, or when the electric motor 104 and the engine 103 operate simultaneously, the rotational speed of the engine 103 matches the rotational speed of the electric motor 104.

[0121] In this embodiment, the rotational speed of the engine 103 is matched with the rotational speed of the electric motor 104, which means that the rotational speed of the engine 103 and the rotational speed of the electric motor 104 are the same.

[0122] In actual operation, when the vehicle is in motion, if the second axle 102 is driven by the electric motor 104, and the rotation is switched to the first axle 101 being driven by the engine 103 while the second axle 102 is driven by the electric motor 104; or if the second axle 102 is driven by the electric motor 104, and the rotation is switched to the first axle 101 being driven only by the engine 103, the speed of the engine 103 needs to be adjusted to match the speed of the electric motor 104, so as to reduce mechanical shock and improve the smoothness of power transmission.

[0123] For example, in the fourth mode, when the energy storage module 106 is low on power and the vehicle speed changes from less than the third threshold to greater than the third threshold, the engine 103 automatically adjusts its speed to match that of the electric motor 104. Then, the engine 103 operates to drive the first axle 101 to rotate, and the electric motor 104 does not operate.

[0124] According to the vehicle provided in the embodiments of this application, by configuring the engine 103 such that when the electric motor 104 is working, the engine 103 is switched to working, or when the electric motor 104 and the engine 103 are working simultaneously, the speed of the engine 103 is matched with the speed of the electric motor 104, which can reduce the mechanical shock of switching from electric motor 104 drive to engine 103 drive, improve the smoothness of power transmission, enable the vehicle to obtain stable power output, and reduce energy conversion loss.

[0125] like Figure 2 As shown, in some embodiments, it also includes:

[0126] The first bevel gear 107 is connected to the engine 103;

[0127] The first clutch 109 has a first end connected to the first bevel gear 107 and a second end connected to the first axle 101.

[0128] The second bevel gear 108 meshes with the first bevel gear 107;

[0129] The second clutch 110 has a first end connected to the second bevel gear 108 and a second end connected to the generator 105.

[0130] The third clutch 111 has its first end connected to the electric motor 104 and its second end connected to the second axle 102.

[0131] In this embodiment, it can be understood that the engine 103 is connected to the first axle 101 based on the closed state of the first clutch 109; the generator 105 rotates based on the rotation of the engine 103 based on the meshing of the second bevel gear 108 and the first bevel gear 107, and the closed state of the second clutch 110; and the electric motor 104 is connected to the second axle 102 based on the closed state of the third clutch 111.

[0132] In actual operation, when the vehicle is in the first driving mode, the first clutch 109 is engaged, while the second clutch 110 and the third clutch 111 are disengaged, and the engine 103 operates to drive the first axle 101 to rotate.

[0133] When the vehicle is in the second driving mode and the energy storage module 106 has sufficient power, the third clutch 111 is engaged, while the first clutch 109 and the second clutch 110 are disengaged. The energy storage module 106 generates electricity to the motor 104, which drives the second axle 102 to rotate. When the energy storage module 106 has insufficient power, the third clutch is engaged, and the second clutch 110 is engaged. The engine 103 drives the first bevel gear 107 to rotate, which in turn drives the second bevel gear 108 to rotate, thereby driving the generator 105 to generate electricity for the energy storage module 106.

[0134] When the vehicle is in the third driving mode, the speed of the engine 103 is adjusted to match the speed of the electric motor 104, the first clutch 109 and the third clutch 111 are engaged, the engine 103 drives the first axle 101 to rotate, and the electric motor 104 drives the second axle 102 to rotate.

[0135] When the energy storage module 106 has insufficient power, the first clutch 109 and the third clutch 111 are engaged, and the second clutch 110 is engaged. The engine 103 drives the first bevel gear 107 to rotate, which in turn drives the second bevel gear 108 to rotate, thereby driving the generator 105 to generate electricity for the energy storage module 106.

[0136] When the vehicle is in the fourth driving mode, and the energy storage module 106 has sufficient power, the third clutch 111 is engaged, and the electric motor 104 drives the second axle 102 to rotate. When the energy storage module 106 has insufficient power and the vehicle speed is less than or equal to the third threshold, the third clutch 111 is engaged, and the second clutch 110 is engaged simultaneously. The engine 103 drives the first bevel gear 107 to rotate, which in turn drives the second bevel gear 108 to rotate, thereby driving the generator 105 to generate electricity for the energy storage module 106. The engine 103 drives the generator 105 to rotate to generate electricity for the energy storage module 106 based on maximum efficiency. When the energy storage module 106 has insufficient power and the vehicle speed is greater than the third threshold, the speed of the engine 103 is adjusted to match the speed of the electric motor 104, the first clutch 109 is engaged, and the second clutch 110 and the third clutch 111 are disengaged, and the engine 103 drives the first axle 101 to rotate.

[0137] According to the vehicle provided in the embodiments of this application, by providing a first bevel gear 107 connected to the engine 103, a first clutch 109 with a first end connected to the first bevel gear 107 and a second end connected to the first axle 101, a second bevel gear 108 meshing with the first bevel gear 107, a second clutch 110 with a first end connected to the second bevel gear 108 and a second end connected to the generator 105, and a third clutch 111 with a first end connected to the electric motor 104 and a second end connected to the second axle 102, flexible switching of vehicle driving modes can be realized.

[0138] This application also provides a vehicle control method.

[0139] The vehicle control method, vehicle control device, electronic device, and readable storage medium provided in this application will be described in detail below with reference to the accompanying drawings and through specific embodiments and application scenarios.

[0140] The vehicle control method can be applied to the terminal, and can be executed by the hardware or software in the terminal.

[0141] The terminal includes, but is not limited to, portable communication devices such as mobile phones or tablets. It should also be understood that, in some embodiments, the terminal may not be a portable communication device, but rather a desktop computer.

[0142] The vehicle control method provided in this application embodiment can be executed by a vehicle or a functional module or entity in the vehicle that can implement the vehicle control method. The vehicle control method provided in this application embodiment is described below using a vehicle as the executing subject.

[0143] like Figure 3As shown, the vehicle control method includes steps 310 and 320.

[0144] Step 310: Obtain the vehicle's driving mode, which includes the first mode, the second mode, the third mode, and the fourth mode;

[0145] In this process, the first mode is pure fuel mode, the second mode is range-extending mode, and the fourth mode is economy driving mode.

[0146] The first, second, and fourth modes are all two-wheel drive modes, that is, the first axle 101 drives or the second axle 102 drives.

[0147] The third mode is the four-wheel drive mode, which is the mode in which the first axle 101 and the second axle 102 drive together.

[0148] Step 320: Based on the driving mode, control the operating status of the engine 103, electric motor 104 and power supply device;

[0149] In this step, engine 103 is connected to the first axle 101 of the vehicle, and electric motor 104 is connected to the second axle 102 of the vehicle.

[0150] The first axle 101 can be either the front axle or the rear axle of the vehicle.

[0151] The second axle 102 can be another axle that is not the first axle 101.

[0152] For example, if the first axle 101 is the front axle, the second axle 102 is the rear axle, and vice versa.

[0153] In actual operation, the engine 103 can drive the first axle 101 to rotate using fuel; the electric motor 104 can drive the second axle 102 to rotate using electrical energy.

[0154] The power supply device includes an energy storage module 106 and a generator 105 connected to the energy storage module 106. The generator 105 is connected to the engine 103 via a drive, and the energy storage module 106 is connected to the motor 104.

[0155] The energy storage module 106 may include one or more battery clusters for storing electrical energy.

[0156] In some embodiments, the energy storage module 106 is connected to the generator 105 and the motor 104 via wiring harness 114.

[0157] In actual operation, the engine 103 can drive the generator 105 to rotate using fuel, thereby enabling the generator 105 to generate electricity to the energy storage module 106. The electrical energy of the energy storage module 106 can be used by the electric motor 104 to drive the second axle 102.

[0158] The energy source for the energy storage module 106 can be generated by the generator 105 or charged by an external power source.

[0159] The work status can be either working or not working.

[0160] In actual operation, the working states of the engine 103, electric motor 104 and power supply device are different under different driving modes. It can be understood that different combinations of the working states of the engine 103, electric motor 104 and power supply device can realize a variety of different driving modes, namely the first mode, the second mode, the third mode and the fourth mode.

[0161] It is understandable that by changing the operating state of the engine 103, the electric motor 104, and the power supply device, the driving mode can be changed. For example, the operating state of the engine 103, the electric motor 104, and the power supply device can be changed to switch the vehicle from two-wheel drive corresponding to the first mode, the second mode, and the fourth mode to four-wheel drive corresponding to the third mode. Of course, conversely, four-wheel drive can also be switched to two-wheel drive.

[0162] During vehicle operation, users can flexibly switch driving modes based on actual conditions or preferences. In some accident scenarios, such as when the vehicle is in the first, second, or fourth mode but the drive wheels are stuck on a soft surface, the vehicle can switch from two-wheel drive (corresponding to the first, second, or fourth mode) to four-wheel drive (corresponding to the third mode), allowing the vehicle to get out of trouble on its own without waiting for rescue.

[0163] According to the vehicle control method provided in the embodiments of this application, by acquiring the vehicle's driving mode, which includes a first mode, a second mode, a third mode, and a fourth mode, the operating states of the engine 103, the electric motor 104, and the power supply device are controlled based on the acquired driving mode. This allows for the combination of different operating states of the engine 103, the electric motor 104, and the power supply device, enabling the vehicle to flexibly select or switch between multiple driving modes based on user needs or preferences in different driving environments, considering factors such as overall economy, low energy consumption, range, and speed, thereby improving the user's driving experience.

[0164] In some embodiments, controlling the operating state of the engine 103, the electric motor 104, and the power supply device based on the driving mode may include:

[0165] When the driving mode is in the first mode, control the engine 103 to work;

[0166] When the driving mode is the second mode, the electric motor 104 is controlled to work, and the working state of the engine 103 is controlled based on the power value of the energy storage module 106.

[0167] When the driving mode is in the third mode, control the engine 103 and the electric motor 104 to work;

[0168] When the driving mode is in the fourth mode, the operating status of the engine 103, electric motor 104 and power supply device is controlled based on the power value of the energy storage module 106 and the vehicle speed.

[0169] In this embodiment, it is understood that in the first mode, the engine 103 can be controlled to work to drive the first axle 101 to rotate. During this period, the control motor 104 and the power supply device are not working, thereby enabling pure fuel two-wheel drive driving and providing users with the driving experience of a pure fuel vehicle.

[0170] In the second mode, the control motor 104 operates to drive the second axle 102 to rotate. During this period, it can be determined whether the engine 103 needs to operate based on the amount of electricity in the energy storage module 106, so as to drive the generator 105 to generate electricity to the energy storage module 106, thereby realizing range-extended drive.

[0171] In actual operation, in the second mode, when the power value of the energy storage module 106 is greater than the first threshold, the generator 105 can be controlled to not work; when the power value of the energy storage module 106 is less than or equal to the first threshold, the generator 105 can be controlled to rotate under the drive of the engine 103 to generate electricity for the energy storage module 106. This enables energy source management for the range-extending mode of the vehicle in the second mode, driven by the electric motor 104, thereby extending the overall driving range in the second mode.

[0172] The first threshold is a safe threshold for the power value of the energy storage module 106.

[0173] In actual operation, when the energy value of the energy storage module 106 is higher than the first threshold, the energy storage module 106 can safely generate electricity to the motor 104. When the energy value of the energy storage module 106 is lower than the first threshold, the energy storage module 106 may not be able to generate electricity to the motor 104 normally.

[0174] In the third mode, the engine 103 is controlled to operate to drive the first axle 101 to rotate, while the electric motor 104 is controlled to operate to drive the second axle 102 to rotate, thereby achieving a higher horsepower four-wheel drive.

[0175] In actual operation, in the third mode, when the energy storage module 106 has sufficient power, the generator 103 can be controlled to drive the first axle 101 to rotate, and at the same time, the energy storage module 106 supplies power to the motor 104 so that the motor 104 can drive the second axle 102 to rotate. When the energy storage module 106 has insufficient power, the generator 103 can be controlled to drive the first axle 101 while simultaneously driving the generator 105 to generate electricity to power the energy storage module 106. The energy storage module 106 then supplies power to the motor 104 so that the motor 104 can drive the second axle 102 to rotate.

[0176] In the fourth mode, the engine 103, electric motor 104 and power supply device can be controlled to enter the corresponding working state based on the power value of the energy storage module 106 and the vehicle speed, with the goal of low economic cost.

[0177] In actual operation, in the fourth mode, when the energy storage module 106 has a charge level greater than the second threshold, the motor 104 can be controlled to drive the second axle 102 to rotate. When the energy storage module 106 has a charge level less than or equal to the second threshold and the vehicle speed is less than or equal to the third threshold, the motor 104 can be controlled to drive the second axle 102 to rotate, wherein the engine 103 drives the generator 105 to rotate to generate electricity for the energy storage module 106 based on maximum efficiency. When the energy storage module 106 has a charge level less than or equal to the second threshold and the vehicle speed is greater than the third threshold, the engine 103 can be controlled to drive the first axle 101 to rotate. This allows for prioritizing electric drive, reducing energy consumption through pure electric drive when the battery is sufficient, and then, when the battery is insufficient, allowing the engine 103 and motor 104 to enter a low-cost driving state based on the vehicle speed. This achieves both a good user experience and economical vehicle operation costs.

[0178] The second threshold is used to determine whether the energy storage module 106 has sufficient power. In some embodiments, the second threshold can be set to be the same as the first threshold.

[0179] The third threshold is used to determine whether the vehicle speed is in the high-speed driving range or the low-speed driving range.

[0180] In actual operation, when the vehicle speed is less than or equal to the third threshold, the vehicle speed is in the low-speed driving range; when the vehicle speed is greater than the third threshold, the vehicle speed is in the high-speed driving range.

[0181] According to the vehicle provided in the embodiments of this application, by controlling the working state of the engine 103, electric motor 104 and power supply device based on different driving modes, the vehicle driving modes including pure fuel drive, range-extended drive, economy drive and four-wheel drive can be realized, thereby improving the flexibility and diversity of vehicle driving mode and enhancing user experience.

[0182] The vehicle control method provided in this application can be executed by a vehicle control device. This application uses the example of a vehicle control device executing the vehicle control method to illustrate the vehicle control device provided in this application.

[0183] This application also provides a vehicle control device.

[0184] like Figure 4 As shown, the vehicle's control device includes: a first processing module 410 and a second processing module 420.

[0185] The first processing module 410 is used to obtain the vehicle's driving mode, which includes a first mode, a second mode, a third mode, and a fourth mode.

[0186] The second processing module 420 is used to control the operating status of the engine 103, the electric motor 104 and the power supply device based on the driving mode; wherein the engine 103 is connected to the first axle 101 of the vehicle and the electric motor 104 is connected to the second axle 102 of the vehicle; the power supply device includes an energy storage module 106 and a generator 105 connected to the energy storage module 106, the generator 105 is connected to the engine 103 by transmission, and the energy storage module 106 is connected to the electric motor 104.

[0187] According to the vehicle control device provided in the embodiments of this application, by acquiring the vehicle's driving mode, which includes a first mode, a second mode, a third mode, and a fourth mode, the operating states of the engine 103, the electric motor 104, and the power supply device are controlled based on the acquired driving mode. This allows for the realization of combinations of different operating states of the engine 103, the electric motor 104, and the power supply device, enabling the vehicle to flexibly select or switch multiple driving modes based on user needs or preferences in different driving environments, considering factors such as overall economy, low energy consumption, range, and speed, thereby improving the user's driving experience.

[0188] In some embodiments, the second processing module 420 may also be used for:

[0189] When the driving mode is in the first mode, control the engine 103 to work;

[0190] When the driving mode is the second mode, the electric motor 104 is controlled to work, and the working state of the engine 103 is controlled based on the power value of the energy storage module 106.

[0191] When the driving mode is in the third mode, control the engine 103 and the electric motor 104 to work;

[0192] When the driving mode is in the fourth mode, the operating status of the engine 103, electric motor 104 and power supply device is controlled based on the power value of the energy storage module 106 and the vehicle speed.
