For example, a process, method, system, product, or device that includes a series of steps or units does not necessarily have to be limited to those steps or units clearly listed, but may include other steps or units not clearly listed or inherent to these processes, methods, products, or devices.

[0025] First, the nouns involved in this application will be explained below.

[0026] Range-extended power vehicle: The range-extended type refers to a strategy in which a vehicle uses a controller to complete the overall vehicle operation control. It mainly appears in vehicles powered by electricity such as new energy vehicles. A range-extended power vehicle can be regarded as a transitional model between a pure electric vehicle and a hybrid vehicle.

[0027] Clutch: A commonly used component in mechanical transmission that can separate or engage the transmission system at any time.

[0028] Direct current-Direct current converter (DC-DC converter for short): A voltage converter that converts the input voltage and effectively outputs a fixed voltage, which can convert one DC voltage into other DC voltages.

[0029] In the prior art provided in the background art, there are at least the following technical problems:

[0030] With the current social environmental protection development theme of carbon neutrality, vehicles are gradually developing towards hybrid vehicle models, pure electric vehicle models, etc. from traditional fuel-powered vehicle models. Among them, both hybrid vehicle models and pure electric vehicle models can use an electric compressor, but the control of the electric compressor is relatively complex and is easily damaged or fails to work due to the influence of high-voltage circuits, resulting in a poor vehicle use experience.

[0031] In view of the above problems, the present application proposes a vehicle control method. A mechanical compressor is adapted on a range-extended power vehicle. The range-extended power vehicle includes a first clutch and a second clutch. The mechanical compressor is connected to an electric motor through the first clutch, and the electric motor is connected to an engine through the second clutch. The current driving source of the electric motor is determined based on the current battery power, and then the states of the first clutch and the second clutch are determined. Thus, whether to drive the mechanical compressor to do work on the refrigerant and whether to charge the battery by generating electricity through the electric motor are determined. Since the solution provided by the present application is to adapt a mechanical compressor on a range-extended power vehicle, it is possible to avoid the problem of poor vehicle use experience caused by using an electric compressor.

[0032] In one embodiment, the vehicle control method can be applied in an application scenario. Figure 1 The following is a schematic structural diagram of the range-extended power vehicle provided by the embodiment of the present application, as Figure 1 shown. The range-extended power vehicle can include a battery, a DC-DC converter, a driving component, and an engine. The battery is connected to the driving component through the DC-DC converter, and the driving component is connected to the engine, and the engine can be a piston engine.

[0033] In the above scenario, the driving component integrates the functions of refrigerant compression and power output. The driving component mainly includes a power output area, an electric motor area, and a compression area, as Figure 2 shown.

[0034] Among them, the power output area mainly includes a second clutch and a driving gear. The second clutch can be a hydraulic clutch. By injecting or discharging hydraulic oil into the cavity in the second clutch structure, the separation and closing of the second clutch are realized, thus avoiding the impact during the closing connection of the clutch.

[0035] The electric motor area mainly includes a stator, a rotor, and a driving shaft. The rotor and the driving shaft can be integrally designed. Under the action of current, the rotor rotates, and the power is transmitted to the compression area and the power output area through the driving shaft.

[0036] The compression area mainly includes a stationary disk, a moving disk, and a first clutch. When the battery or the air conditioner has a cooling request, the driving shaft in the electric motor area drives the moving disk to rotate. During the rotation of the moving disk, it is pressed against the stationary disk, thereby realizing the compression of the refrigerant. The first clutch can be a hydraulic clutch. By injecting or discharging hydraulic oil into the cavity in the first clutch structure, the separation and closing of the first clutch are realized, thus avoiding the impact during the closing connection of the clutch.

[0037] In the above scenario, the range-extended power vehicle can also include a refrigerant inlet and a refrigerant outlet, as Figure 2As shown, the refrigerant inlet can be set in the motor area, the refrigerant outlet can be set in the compression area, and a channel can be set between the motor area and the compression area for the refrigerant to flow from the motor area into the compression area. Moreover, a cover plate can also be set between the motor area and the power output area, and sealed by the cover plate to prevent the refrigerant from flowing from the motor area into the power output area. Setting the refrigerant inlet in the motor area can achieve cooling the motor area with the refrigerant first and then entering the compression stage of the refrigerant.

[0038] Combined with the above scenario, the technical solutions of the vehicle control method provided by this application will be described in detail through several specific embodiments below.

[0039] This application provides a vehicle control method, which can be used for the operation control of an extended-range power vehicle including a mechanical compressor. The extended-range power vehicle includes a first clutch and a second clutch. The mechanical compressor is connected to the motor through the first clutch, and the motor is connected to the engine through the second clutch. Figure 3 is a flowchart of the vehicle control method provided by an embodiment of this application. As Figure 3 shown, the method includes the following steps:

[0040] S301: Determine whether the current battery power is greater than the power threshold.

[0041] In this step, the power threshold can be a preset battery power value that can drive the motor to operate. When the current battery power is greater than the power threshold, it means that the current battery power can be used to drive the motor to operate; when the current battery power is less than or equal to the power threshold, it means that the current battery power cannot drive the motor to operate. At this time, the current drive source of the motor needs to be changed, and the battery needs to be charged.

[0042] S302: Determine the current drive source of the motor according to the determination result.

[0043] In this step, when the current battery power is greater than the power threshold, it means that the current battery power can be used to drive the motor to operate. At this time, the current drive source of the motor is the battery; when the current battery power is less than or equal to the power threshold, it means that the current battery power cannot drive the motor to operate. At this time, the current drive source of the motor is the engine.

[0044] S303: Control the state of the second clutch based on the current drive source.

[0045] In this step, the states of the second clutch include disengaged and engaged. Since the motor is connected to the engine through the second clutch, if the current drive source is the engine, the state of the second clutch can be controlled to be engaged, so as to drive the motor to operate through the engine; if the current drive source is the battery, the engine is not required to provide power for the motor, so the second clutch can be controlled to disengage.

[0046] S304: Control the state of the first clutch based on whether a cooling request for the battery and / or the air conditioner is detected.

[0047] In this step, the states of the first clutch include disengaged and engaged. Since the mechanical compressor is connected to the motor through the first clutch, when a cooling request for the battery and / or the air conditioner is detected, it indicates that the mechanical compressor needs to perform refrigerant work, so the state of the first clutch needs to be controlled to be engaged, so that the motor can drive the mechanical compressor to perform refrigerant work; when a cooling request for the battery and / or the air conditioner is not detected, it indicates that the mechanical compressor does not need to perform refrigerant work, so the motor does not need to drive the mechanical compressor to perform refrigerant work, so the state of the first clutch needs to be controlled to be disengaged.

[0048] In the above solution, by controlling the states of the first clutch and the second clutch, the power source of the vehicle operation can be controlled, and the mechanical compressor can be controlled, thus avoiding the problems that the control of the electric compressor is relatively complex and is easily damaged or does not work due to the influence of the high-voltage circuit. Therefore, the use experience of the vehicle is improved.

[0049] The vehicle control method provided in this embodiment adapts a mechanical compressor on an extended-range power vehicle, and then determines whether the current drive source of the motor is the battery or the engine based on the current battery power; since the motor can be connected to the engine through the second clutch, after determining the current drive source of the motor, the state of the second clutch can be controlled to be disengaged or engaged; since the mechanical compressor can be connected to the motor through the first clutch, the state of the first clutch can be controlled to be disengaged or engaged by determining whether a cooling request for the battery or the air conditioner is detected, so that it can be determined whether to drive the mechanical compressor to perform refrigerant work according to the states of the first clutch and the second clutch, and whether to charge the battery by generating electricity through the motor, thus improving the use experience of the vehicle.

[0050] In one embodiment, controlling the state of the second clutch based on the current drive source includes: in response to the current drive source being the battery, controlling the second clutch to disengage; and / or, in response to the current drive source being the engine, controlling the second clutch to engage.

[0051] In this solution, when the current battery power is greater than the power threshold, it indicates that the current battery power can be used to drive the motor. Therefore, the current driving source of the motor is the battery. Thus, there is no need for the engine to drive the motor, and accordingly, the state of the second clutch can be controlled to be disengaged, so that the power transmission between the driving gear and the engine flywheel will terminate, and the engine will stop running.

[0052] In the above solution, when the current battery power is less than or equal to the power threshold, it indicates that the current battery power cannot be used to drive the motor. At this time, the engine is required to drive the motor, that is, the current power source of the motor is the engine. Therefore, the state of the second clutch can be controlled to be engaged.

[0053] In the above solution, when the current power source of the motor is the engine, after the second clutch is engaged, the current battery power can be used to drive the rotation of the rotor in the motor area, driving the drive shaft to transmit power to the driving gear, thereby assisting the start of the engine. At this time, although the current battery power is less than the power threshold, the power required to drive the rotor rotation is very small. Therefore, the current battery power can meet the requirement of assisting the start of the engine.

[0054] In one embodiment, the state of the first clutch is controlled based on whether a cooling request for the battery and / or the air conditioner is detected, including: controlling the first clutch to be engaged in response to detecting the cooling request; and / or, controlling the first clutch to be disengaged in response to not detecting the cooling request.

[0055] In this solution, since the mechanical compressor is connected to the motor through the first clutch, if a cooling request for the battery and / or the air conditioner is detected, it indicates that the mechanical compressor needs to perform refrigerant work. At this time, the motor needs to drive the mechanical compressor, so the first clutch needs to be controlled to be engaged; if a cooling request for the battery and / or the air conditioner is not detected, it indicates that the mechanical compressor does not need to perform refrigerant work, and at this time, the first clutch can be controlled to be disengaged, so that the motor cannot drive the mechanical compressor.

[0056] In one embodiment, it further includes: after controlling the second clutch to be disengaged, in response to detecting the cooling request, controlling the battery to drive the motor to operate so that the mechanical compressor performs refrigerant work; after controlling the second clutch to be engaged, in response to detecting the cooling request, controlling the engine to drive the motor to operate so that the mechanical compressor performs refrigerant work and the motor charges the battery; after controlling the second clutch to be engaged, in response to not detecting the cooling request, controlling the engine to drive the motor to charge the battery.

[0057] In this solution, after controlling the second clutch to disengage, the engine stops running. At this time, the current power of the battery can be used to drive the motor. Therefore, if a cooling request for the battery and / or the air conditioner is detected, the battery can be controlled to drive the motor to run, thereby controlling the mechanical compressor to perform refrigerant work. Optionally, after controlling the second clutch to disengage, if no cooling request for the battery and / or the air conditioner is detected, the first clutch can be controlled to disengage. At this time, the battery only serves as a power source for driving the vehicle.

[0058] In the above solution, after controlling the second clutch to engage, the engine starts running. At this time, the current power of the battery cannot be used to drive the motor. Therefore, if a cooling request for the battery and / or the air conditioner is detected, the engine can be controlled to be the current power source of the motor to drive the motor to run, thereby controlling the mechanical compressor to perform refrigerant work. At the same time, due to the insufficient current power of the battery, when the engine drives the motor, the motor can also enter the power generation mode to charge the battery through the DC-DC converter.

[0059] In the above solution, after controlling the second clutch to engage, the engine starts running. At this time, the current power of the battery cannot be used to drive the motor. Therefore, if no cooling request for the battery and / or the air conditioner is detected, the engine can be controlled to be the current power source of the motor to only drive the motor into the power generation mode to charge the battery.

[0060] In one embodiment, controlling the engine to drive the motor to run includes: during the operation of the engine, controlling the engine to drive the motor to be in the forward braking state; and / or, when the engine start is detected, controlling the engine to drive the motor to be in the accelerating forward state.

[0061] In this solution, the operating state of the motor can be represented by Figure 4 In Figure 4 , the abscissa can be used to represent the rotational speed of the motor, and the ordinate can be used to represent the torque of the motor. When the engine is running, the state of the second clutch is engaged. At this time, the motor can operate in the fourth quadrant as shown in Figure 4 , that is, at this time the motor is in the forward braking state (or power generation state). If there is a cooling request for the battery and / or the air conditioner, the first clutch is controlled to engage, and the engine drives the mechanical compressor to perform refrigerant work synchronously through the drive shaft.

[0062] In the above solution, when the engine just starts, the state of the second clutch is engaged. At this time, the motor can operate in the first quadrant as shown in Figure 4 , that is, at this time the motor is in the accelerating forward state. The engine can be assisted to start through the motor, that is, the motor can drive the drive gear to rotate through the drive shaft, thereby driving the engine to start.

[0063] In the above solution, when the motor operates in the first quadrant, the torque of the motor is positive and the rotational speed is positive; when the motor operates in the fourth quadrant, the torque of the motor is negative and the rotational speed is positive.

[0064] In one embodiment, controlling the battery to drive the motor to operate includes: controlling the battery to drive the motor to be in an accelerated forward state.

[0065] In this solution, when the engine stops running, the second clutch is in a disengaged state. At this time, the motor can operate in the first quadrant as shown in Figure 4 . If there is a cooling request for the battery and / or the air conditioner, control the first clutch to close, and the engine synchronously drives the mechanical compressor through the drive shaft to perform refrigerant work.

[0066] In the above solution, in addition to operating in the first and fourth quadrants, the motor can also operate in the second and third quadrants. When the motor operates in the second quadrant, the motor is in a reverse braking state. At this time, the torque of the motor is positive and the rotational speed is negative; when the motor operates in the third quadrant, the motor is in an accelerated reverse state. At this time, the torque of the motor is negative and the rotational speed is negative.

[0067] In one embodiment, according to the determination result, determining the drive source of the motor includes: in response to the determination result that the current battery power is greater than the power threshold, determining the drive source of the motor to be the battery; and / or, in response to the current battery power being less than or equal to the power threshold, determining the drive source of the motor to be the engine.

[0068] Generally speaking, the technical solution provided by this application adapts a mechanical compressor for an extended-range power vehicle, thereby reducing the control difficulty of the compressor, and is a technical implementation method that can improve the use experience of the vehicle.

[0069] This application also provides a vehicle control device, which is used for the operation control of an extended-range power vehicle including a mechanical compressor. The extended-range power vehicle includes a first clutch and a second clutch. The mechanical compressor is connected to the motor through the first clutch, and the motor is connected to the engine through the second clutch.

[0077] Optionally, when the third control module controls the engine-driven motor to operate, it may further be specifically configured to: during the operation of the engine, control the engine-driven motor to be in a forward braking state; and / or, when detecting the start of the engine, control the engine-driven motor to be in an accelerating forward state.
