[0029] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of the present invention.

[0030] It should be noted that the terms "first," "second," etc., in the specification, claims, and accompanying drawings of this invention are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments of the invention described herein can be implemented in orders other than those illustrated or described herein. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover a non-exclusive inclusion; for example, a process, method, system, product, or apparatus that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or apparatus.

[0031] According to an embodiment of the present invention, a method embodiment for vehicle control is provided. It should be noted that the steps shown in the flowchart in the accompanying drawings can be executed in a computer system such as a set of computer-executable instructions. Furthermore, although a logical order is shown in the flowchart, in some cases, the steps shown or described may be executed in a different order than that shown here.

[0032] Figure 1 This is a flowchart illustrating a vehicle control method according to an embodiment of the present invention, such as... Figure 1 As shown, the method includes the following steps:

[0033] Step S102: Obtain the user's driving needs for the vehicle and the state of charge of the vehicle battery.

[0034] The aforementioned user driving needs can refer to the driver's real-time requests for vehicle acceleration, speed, or torque, and can be used to reflect the driver's driving style and current driving conditions.

[0035] In one optional embodiment of this invention, considering the diversity of power sources and the complexity of energy management in hybrid vehicles, the control system can dynamically adjust the energy distribution among multiple power devices during engine shutdown or inefficient operation. This allows for the stable provision of power to the vehicle from multiple power devices, reducing energy loss. The control system can first acquire the user's driving needs to determine the vehicle's current power demand level. Simultaneously, the control system can acquire the vehicle's battery state of charge (SOC) to determine the battery's remaining energy and charging / discharging capacity, thereby achieving an optimal energy distribution strategy.

[0036] Step S104: Based on user driving needs and state of charge, determine the operating modes of multiple power devices on the vehicle.

[0037] Among them, the operating mode is used to characterize the collaborative working method between different power devices.

[0038] The aforementioned operating mode can refer to a mode in which multiple power devices, such as engines, motors, and clutches, provide power to the vehicle. The cooperative working methods of these multiple power devices can differ under different operating modes.

[0039] In one optional embodiment, to intelligently select the most energy-efficient and effective power configuration based on the vehicle's actual needs and battery status, the control system, after obtaining the user's driving requirements and the vehicle's battery state of charge, can use these requirements to determine the operating modes of multiple power devices on the vehicle. These operating modes then determine the collaborative working methods between the different power devices. For example, when the vehicle requires low torque and the battery has sufficient charge, the system may select pure electric mode, driving the vehicle solely with the electric motor; while in situations of high power demand or insufficient battery charge, it may activate parallel drive mode or series mode to fully utilize the combined capabilities of the engine and electric motor.

[0040] Step S106: Based on user driving needs and operating modes, determine the equipment control parameters for multiple power devices.

[0041] In one optional embodiment, in order to more accurately control the working state of each of the multiple power devices and ensure system stability and performance, after determining the operating mode of the multiple power devices, the control system can further determine the equipment control parameters of the multiple power devices according to the user's driving needs and operating mode, thereby adjusting the power output, torque distribution and operating state of the engine and motor and the cooling fan to achieve the expected energy utilization efficiency.

[0042] Step S108: Control the operation of multiple power devices based on equipment control parameters to control vehicle operation.

[0043] In one optional embodiment, after determining the equipment control parameters of multiple power devices, the control system can control the operation of the multiple power devices according to the equipment control parameters to control the vehicle's movement, thereby meeting the user's needs for vehicle use.

[0044] In this embodiment of the invention, the following methods are employed: acquiring the user's driving needs and the state of charge (SBC) of the vehicle's battery; determining the operating modes of multiple power devices on the vehicle based on the user's driving needs and SBC; determining the equipment control parameters of the multiple power devices based on the user's driving needs and operating modes; and controlling the operation of the multiple power devices based on the equipment control parameters. By determining the collaborative working method between different multiple power devices on the vehicle according to the user's driving needs and the vehicle's battery SBC, i.e., determining the operating modes of multiple power devices and simultaneously determining the equipment control parameters matching the operating modes, the control system can fully and rationally utilize the performance of multiple power devices based on the operating modes and equipment control parameters, providing balanced and stable power to the vehicle, thereby meeting the user's driving needs, improving the user's driving experience, and thus solving the technical problem in related technologies where the stability of collaborative control of multiple power devices on a vehicle is poor, affecting the user's driving experience.

[0045] Furthermore, based on user driving needs and state of charge, the operating modes of multiple power devices on the vehicle are determined, including: determining the vehicle's drive torque requirement based on user driving needs; matching the drive torque requirement with a preset torque range to obtain a torque matching result, wherein the torque matching result is used to characterize whether the drive torque requirement is within the preset torque range; matching the state of charge with a preset charge range to obtain a charge matching result, wherein the charge matching result is used to characterize whether the state of charge is within the preset charge range; and determining the operating mode based on the torque matching result and the charge matching result.

[0046] In one optional embodiment, to accurately determine the operating modes of multiple power devices on the vehicle, the control system can first determine the vehicle's drive torque requirement based on the user's driving needs. Then, it matches the drive torque requirement with a preset torque range to obtain a torque matching result. This result is used to determine whether the drive torque requirement is within the preset torque range. Simultaneously, the state of charge (SOC) can be matched with a preset charge range to obtain a charge matching result. This result is used to determine whether the SOC is within the preset charge range. Finally, the control system can determine the operating mode based on the torque matching result and the charge matching result.

[0047] Based on this, by using preset torque range and preset battery range to determine the operating mode, it can be ensured that the vehicle selects the most appropriate power distribution strategy under different operating conditions, thereby achieving efficient use of energy, adjusting the driving experience, and reducing energy waste and emissions.

[0048] Furthermore, based on the torque matching result and the battery level matching result, the operating mode is determined, including: in response to the torque matching result indicating that the drive torque demand is less than the minimum value in the preset torque range, and the battery level matching result indicating that the state of charge is greater than the maximum value in the preset battery level range, the operating mode is determined to be a pure electric operating mode; in response to the torque matching result indicating that the drive torque demand is less than the minimum value in the preset torque range, and the battery level matching result indicating that the state of charge is less than the minimum value in the preset battery level range, the operating mode is determined to be a series operating mode; in response to the torque matching result indicating that the drive torque demand is within the preset torque range, the operating mode is determined to be an engine direct drive mode; and in response to the torque matching result indicating that the drive torque demand is greater than the maximum value in the preset torque range, the operating mode is determined to be a parallel drive mode.

[0049] In one optional embodiment, when determining the operating mode based on the torque matching result and the power matching result, the control system may determine the operating mode as pure electric operating mode if the torque matching result is that the drive torque demand is less than the minimum value in the preset torque range and the power matching result is that the state of charge is greater than the maximum value in the preset power range.

[0050] If the torque matching result is that the drive torque demand is less than the minimum value in the preset torque range, and the charge matching result is that the state of charge is less than the minimum value in the preset charge range, the operating mode can be determined to be the series operation mode.

[0051] If the torque matching result indicates that the drive torque requirement is within the preset torque range, the operating mode can be determined as engine direct drive mode.

[0052] If the torque matching result shows that the drive torque requirement is greater than the maximum value in the preset torque range, the operating mode can be determined to be parallel drive mode.

[0053] The pure electric operation mode refers to using only the electric motor to power the vehicle when low torque demand is required and the battery is fully charged, while the engine remains off to maximize battery energy utilization and achieve zero-emission driving. The series operation mode refers to starting the engine and using it only to drive the generator (with the electric motor serving as the sole power source for the drive wheels) when torque demand is low but battery charge is insufficient, supplying power to the electric motor and charging the battery simultaneously. The engine direct drive mode refers to the engine directly driving the wheels when drive torque demand is moderate and battery charge is adequate, with the electric motor rotating with the engine without participating in driving. This mode offers high system efficiency and is suitable for urban cruising and similar conditions. The parallel drive mode refers to the engine and electric motor simultaneously providing power to the vehicle when high torque demand is required, meeting higher power demands. The electric motor can also participate in energy recovery, increasing the flexibility and responsiveness of the powertrain.

[0054] Furthermore, based on user driving needs and operating modes, the equipment control parameters of multiple power devices are determined, including: determining the operating mode of multiple power devices based on the operating mode; inputting the equipment operating mode and user driving needs into the parameter construction model, and using the parameter construction model to determine the equipment control parameters.

[0055] In one optional embodiment, in order to improve the accuracy of the determined equipment control parameters during the process of determining equipment control parameters, the control system can first determine the operating mode of multiple power devices based on the determined operating mode, so as to adjust the specific working state, torque distribution and speed setting of the engine and motor according to the operating mode, to ensure the operation of the power system in the current mode.

[0056] After determining the operating mode, the control system can input the operating mode and user driving requirements into the pre-trained parameter construction model, and use the parameter construction model to determine the equipment control parameters, thereby improving the rationality of the determined equipment control parameters.

[0057] Furthermore, the multiple power devices include: a first motor, a second motor, and a first clutch. The first motor is connected to the vehicle's transmission system, the second motor is connected to the vehicle's engine, and the first clutch is deployed between the second motor and the engine. Based on the operating mode, the operating mode of the multiple power devices is determined, including: in response to the operating mode being a pure electric operating mode, determining the operating mode of the first motor to provide power to the vehicle; determining the operating mode of the second motor to drive the fan in the cooling system; and determining the operating mode of the first clutch to disengage.

[0058] In one optional embodiment, the multiple power devices may include at least the aforementioned first motor, second motor, and first clutch. The first motor is connected to the vehicle's transmission system, the second motor is connected to the vehicle's engine, and the first clutch is positioned between the second motor and the engine to control the mechanical connection between them, enabling flexible switching of the power system. Correspondingly, the first motor may refer to a P2 motor, directly involved in vehicle driving, while the second motor may refer to a P0 motor, primarily used for engine starting and auxiliary power generation.

[0059] Based on this, when determining the operating mode of multiple power devices, if the determined operating mode is pure electric operating mode, the control system can determine that the first motor operates to provide power to the vehicle, and the second motor operates to drive the fan in the cooling system, while simultaneously determining that the first clutch operates to disengage.

[0060] Furthermore, the multiple power devices also include: a second clutch and an engine, the second clutch being deployed between the first motor and the transmission system; the method further includes: in response to the operating mode being a series operating mode, determining the engine's operating mode as driving the second motor and fan; determining the first motor's operating mode as providing power to the vehicle; determining the first clutch's operating mode as first clutch engagement; and determining the second clutch's operating mode as second clutch disengagement.

[0061] In one alternative embodiment, the multiple power devices may further include a second clutch and an engine. The second clutch is deployed between the first motor and the transmission system and can be used to control the power transmission between the first motor and the transmission system, so that in a specific operating mode, the mechanical connection between the first motor and the vehicle drive shaft can be effectively isolated or connected.

[0062] Based on this, when determining the operating mode of multiple power devices, if the determined operating mode is a series operating mode, the control system can determine that the engine operates to drive the second motor and fan, the first motor operates to provide power to the vehicle, the first clutch operates to engage, and the second clutch operates to disengage.

[0063] Furthermore, the above method also includes: in response to the operating mode being engine direct drive mode, determining the engine's operating mode as providing power to the vehicle and driving the fan to operate; determining the first motor's operating mode as follow-rotating; determining the second motor's operating mode as follow-rotating; and determining the first clutch's operating mode as first clutch engagement.

[0064] In one optional embodiment, if the determined operating mode is engine direct drive mode, the control system can determine that the engine's operating mode is to provide power to the vehicle and drive the fan. Simultaneously, the control system can determine that the first motor operates as a follower, meaning the first motor does not actively output torque but passively rotates only in response to the operation of the engine and transmission system. It can also determine that the second motor operates as a follower, meaning the second motor does not actively output or consume energy but passively rotates only in response to the engine's operation. Furthermore, it can determine that the first clutch operates as a first clutch engaged.

[0065] Furthermore, the above method also includes: in response to the operating mode being a parallel drive mode, determining the engine's operating mode as providing power to the vehicle and driving the fan to operate; determining the first motor's operating mode as providing power to the vehicle; determining the second motor's operating mode as following rotation; and determining the first clutch's operating mode as first clutch engagement.

[0066] In one optional embodiment, if the determined operating mode is a parallel drive mode, the control system can determine that the engine's operating mode is to provide power to the vehicle and drive the fan. Simultaneously, it can determine that the first motor's operating mode is to provide power to the vehicle, the second motor's operating mode is to follow the rotation, and the first clutch's operating mode is to engage.
