[0038] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only for illustration and explanation of the embodiments of this application and are not intended to limit the embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0039] Figure 1 A schematic flowchart illustrating a control method for an emergency vehicle according to an embodiment of this application is shown. Figure 1 As shown in one embodiment of this application, a control method for an emergency vehicle is provided, comprising the following steps:

[0040] S102, Obtain mode switching instructions for emergency vehicles.

[0041] S104 controls the emergency vehicle to enter the corresponding power mode according to the mode switching command.

[0042] S106, Obtain status control instructions for emergency vehicles.

[0043] S108 controls emergency vehicles to enter the corresponding working state according to status control instructions.

[0044] S110 identifies the target clutch among multiple clutches in power mode and operating state.

[0045] S112 controls the target clutch to close, so as to provide corresponding power through the electric motor and / or fuel engine connected to the target clutch.

[0046] Traditional fuel-powered emergency vehicles rely on their engines to power both the axles and the vehicle's superstructure. For example, the engine in an emergency fire truck powers the axles, water pump, and lifting components. In some situations, these vehicles need to perform water spraying operations while in motion. Therefore, emergency vehicles require high-powered fuel engines, which are expensive and consume a lot of fuel. Furthermore, if the fuel engine fails, the emergency vehicle cannot operate. This solution, however, uses both an electric motor and a fuel engine to power the vehicle's actuators, reducing the load on the fuel engine. The electric motor and fuel engine work together to provide power to the emergency vehicle.

[0047] In this embodiment, the emergency vehicle includes a motor, a fuel engine, and multiple clutches, with the motor and fuel engine connected via clutches. First, the controller receives a mode switching command for the emergency vehicle, allowing the user to switch modes to enable more energy-efficient and effective operation. Upon receiving the mode switching command, the controller can control the emergency vehicle to enter the corresponding power mode. For example, the controller can switch the emergency vehicle from hybrid mode to pure electric mode based on the user's command. The controller also receives a status control command for the emergency vehicle, allowing it to enter the corresponding operating state. The controller can determine a target clutch among the multiple clutches in the power mode and operating state. Since the emergency vehicle includes multiple clutches, the controller can control the vehicle's power transmission by controlling the closing or opening of these clutches. After determining the power mode and operating state, the controller can determine the target clutch among the multiple clutches. The controller controls the target clutch to close, providing corresponding power through the electrode and / or fuel engine connected to the target clutch.

[0048] Using the above method, the target clutch engagement can be controlled according to user instructions, allowing the electric motor and the fuel engine to provide power to different actuators. This reduces the required output power of the fuel engine, thereby lowering its cost. The emergency vehicle described in this application can still operate even if either the electric motor or the fuel engine fails, thanks to clever clutch control, by utilizing another power source. This provides better adaptability compared to traditional fuel-powered emergency vehicles.

[0049] In one embodiment, the emergency vehicle further includes a mains power module and an energy storage module, the mains power module being connected to the energy storage module, and the energy storage module being connected to the motor. The power mode includes at least one of a hybrid mode, a pure fuel mode, a pure electric mode, and a mains power mode. Controlling the emergency vehicle to enter the corresponding power mode according to the mode switching command includes: in the hybrid mode, controlling the motor and the fuel engine to start together to drive the emergency vehicle; in the pure fuel mode, controlling the motor to start to drive the emergency vehicle; in the pure electric mode, controlling the fuel engine to start to drive the emergency vehicle; and in the mains power mode, controlling the mains power module to charge the energy storage module to provide power to the motor through the energy storage module, and controlling the motor to start to drive the emergency vehicle.

[0050] A mains power module is a module that can accept external power. In mains power mode, it charges the emergency vehicle, allowing it to operate for extended periods. An energy storage module stores electrical energy. It receives and stores energy from the mains power module and provides power to the motor when it starts. Hybrid mode means both the motor and the combustion engine power the emergency vehicle. Power is supplied to different actuators based on the controller's clutch control to meet the high-power demands of the emergency vehicle. Pure fuel mode means the controller powers the combustion engine, transmitting power to the actuators and motor to drive the emergency vehicle. Pure fuel mode is suitable for situations where the energy storage device or motor is damaged. Pure electric mode means the controller powers the emergency vehicle through the motor, transmitting power to the actuators to drive the vehicle. Pure electric mode is suitable for low-power conditions such as maintenance, slow driving, and cruising. Mains power mode refers to emergency vehicles connected to an external power source. Electrical energy is transmitted to the motor through the mains power module and energy storage device, and the controller controls the motor to provide power to the emergency vehicle. Mains power mode can be used for emergency vehicles that are parked or have cruise circuits installed for cruising.

[0051] In one embodiment, the emergency vehicle further includes an energy storage module. The method further includes: acquiring the current motion state of the emergency vehicle; when the emergency vehicle is going downhill or decelerating, controlling the motor to convert the kinetic energy of the actuator and the fuel engine into electrical energy and transmitting it to the energy storage module. When the controller determines that the emergency vehicle is going downhill or decelerating, the controller can control the motor to acquire the kinetic energy of the actuator and the fuel engine, convert it into electrical energy, and store the converted electrical energy in the storage module. When the controller controls the motor to move, the motor can acquire electrical energy from the storage module. This method enables efficient use of energy and reduces resource consumption.

[0052] In one embodiment, such as Figure 2 The diagram shown is a schematic of the control system 200 of an emergency vehicle. The emergency vehicle also includes a power take-off (PTO), a gearbox, a motor gearbox, a water pump PTO, and a transfer case. Multiple clutches are included, such as clutch L1, clutch L2, clutch L3, clutch L4, clutch L5, clutch L6, clutch L7, clutch L8, and clutch L9. The motors include a main motor and a secondary motor. The fuel engine is connected to the gearbox via clutch L1, the main motor to the motor gearbox via clutch L2, the gearbox to the motor gearbox via clutch L3, the main motor to the water pump PTO via clutch L4, the motor gearbox to the transfer case via clutch L5, the gearbox to the PTO via clutch L6, the main motor to the secondary motor via clutch L7, the secondary motor to the PTO via clutch L8, and the secondary motor to the fuel engine via clutch L9. The superstructure power take-off (PTO) transmits the acquired power to the hydraulic pump, driving the movement of the superstructure components of the emergency vehicle. The gearbox is a power transmission device that acquires power from the internal combustion engine and converts and transmits it to the superstructure controller and the motor gearbox. The motor gearbox acquires power from the main motor and / or the gearbox and transmits it to the transfer case. The transfer case is a power transmission device that distributes the power from the motor gearbox to actuators connected to the transfer case, such as the emergency steering pump, the first steering drive axle, the second drive axle, and the third drive axle. The water pump PTO acquires power from the main motor and transmits it to the water pump. The controllers include the motor drive controller and the vehicle controller, and the energy storage module includes the on-board charger and the energy storage system. Power from an external source can be transmitted to the energy storage system via the mains power module and the on-board charger. The energy storage system can supply power to the motor drive controller, the vehicle controller, the main motor, and the secondary motor.

[0053] In one embodiment, determining the target clutch among multiple clutches in a power mode and operating state includes: when the emergency vehicle is in hybrid mode startup state, the target clutches are the second clutch L2, the third clutch L3, and the fifth clutch L5. When the emergency vehicle is in hybrid mode startup state, the second clutch L2, the third clutch L3, and the fifth clutch L5 are engaged, so that the power of the main motor is transmitted through the motor gearbox to the motor gearbox and the transfer case, and then through the transfer case to the drive axle to start the vehicle.

[0054] In one embodiment, determining the target clutch among multiple clutches in different power modes and operating states includes, when the emergency vehicle is in hybrid mode, the target clutches are the first clutch L1, the second clutch L2, the third clutch L3, and the fifth clutch L5. After the first clutch L1, the second clutch L2, the third clutch L3, and the fifth clutch L5 are engaged, the fuel engine and the electrode work together to provide power to the drive axle, which can provide higher drive power to the axle, enabling the emergency vehicle to start at high speed or climb hills.

[0055] In one embodiment, determining the target clutch among multiple clutches in a power mode and operating state includes: when the emergency vehicle is in hybrid mode and performing water spraying operation while driving, and the driving speed is lower than a preset speed, the target clutches are the first clutch L1, the second clutch L2, the third clutch L3, the fourth clutch L4, the fifth clutch L5, and the sixth clutch L6. When the emergency vehicle is in hybrid mode and performing water spraying operation while driving, and the driving speed is lower than a preset speed, the controller controls the first clutch L1, the second clutch L2, the third clutch L3, the fourth clutch L4, the fifth clutch L5, and the sixth clutch L6 to close. Part of the power from the fuel engine is transmitted to the superstructure components through the gearbox and the superstructure power take-off. The fuel engine transmits part of its power through the gearbox to the transfer case through the gearbox and the motor gearbox, so that the transfer case transmits power to the drive axle. The main motor transmits power to the water pump power take-off and the motor gearbox, and the motor gearbox transmits the power obtained from the gearbox and the main motor to the transfer case. This method allows emergency vehicles to perform water spraying while traveling at speeds below a preset level, maximizing the use of the output power of the electric motor and the fuel engine, and avoiding slow movement caused by insufficient output power from a single power source.

[0056] In one embodiment, determining the target clutch among multiple clutches in a power mode and operating state includes: when the emergency vehicle is in hybrid mode and performing water spraying operation during driving, and the driving speed is higher than or equal to a preset speed, the target clutches are the first clutch L1, the second clutch L2, the third clutch L3, the fourth clutch L4, and the fifth clutch L5. At speeds higher than or equal to the preset speed, continued driving of the superstructure components by the emergency vehicle may pose a danger; therefore, the controller can disengage the sixth clutch L6 between the transmission and the superstructure power take-off to ensure safe driving of the emergency vehicle.

[0057] In one embodiment, determining the target clutch among multiple clutches in different power modes and operating states includes: when the emergency vehicle is in hybrid mode and water spraying is performed while parked, the target clutches are the first clutch L1, the fourth clutch L4, and the sixth clutch L6. When the emergency vehicle is parked, the fuel engine transmits power to the superstructure power take-off via the first clutch L1, the transmission, and the sixth clutch L6, while the main motor transmits power to the water pump power take-off via the fourth clutch L4.

[0058] In one embodiment, determining the target clutch among multiple clutches in power mode and operating state includes: when the emergency vehicle is started or driven in pure electric mode, the target clutches are the second clutch L2 and the fifth clutch L5. When the emergency vehicle is started or driven in pure electric mode, the main motor transmits power to the drive axle through the second clutch L2, the motor gearbox, the fifth clutch L5, and the transfer case to enable the emergency vehicle to start and drive.

[0059] In one embodiment, determining the target clutch among multiple clutches in the power mode and operating state includes: when the emergency vehicle is in pure electric mode and performing water spraying operation while driving, and the driving speed is lower than a preset speed, the target clutches are the second clutch L2, the fourth clutch L4, the fifth clutch L5, and the eighth clutch L8. When the emergency vehicle is in pure electric mode and performing water spraying operation while driving, and the driving speed is lower than the preset speed, the controller controls the second clutch L2, the fourth clutch L4, the fifth clutch L5, and the eighth clutch L8 to close, and controls the main motor and the secondary motor to work, transmitting the power of the main motor to the water pump power take-off and the speed distribution box, and transmitting the power of the secondary motor to the superstructure power take-off.

[0060] In one embodiment, determining the target clutch among multiple clutches in power mode and operating state includes: when the emergency vehicle is in pure electric mode and performing water spraying operation while driving at a speed higher than or equal to a preset speed, the target clutches are the second clutch L2, the fourth clutch L4, the fifth clutch L5, and the seventh clutch L7. When the emergency vehicle is in pure electric mode and performing water spraying operation while driving at a speed higher than or equal to a preset speed, if there is a danger in the movement of the emergency vehicle's drive superstructure components, the controller controls the second clutch L2, the fourth clutch L4, the fifth clutch L5, and the seventh clutch L7 to close, and the eighth clutch L8 to disengage. Power from the secondary motor is transmitted to the transfer case and the water pump power take-off via the main motor, enabling the emergency vehicle to perform water spraying operation at a speed higher than or equal to the preset speed.

[0061] In one embodiment, determining the target clutch among multiple clutches in power mode and operating state includes: when the emergency vehicle is in pure electric mode and performing water spraying operation while parked, the target clutches are the fourth clutch L4, the seventh clutch L7, and the eighth clutch L8. When the emergency vehicle is in pure electric mode and performing water spraying operation while parked, the controller controls the fourth clutch L4, the seventh clutch L7, and the eighth clutch L8 to close, so that power from the main motor and the secondary motor is transmitted to the water pump power take-off and the superstructure power take-off, supporting the emergency vehicle's parking operation.

[0062] In one embodiment, determining the target clutch among multiple clutches in power mode and operating state includes: when the emergency vehicle is driving or starting in pure fuel mode, the target clutches are the first clutch L1, the third clutch L3, and the fifth clutch L5. When the emergency vehicle is driving or starting in pure fuel mode, the controller controls the first clutch L1, the third clutch L3, and the fifth clutch L5 to close, so that the power of the fuel engine is transmitted to the drive electric axle through the first clutch L1, the transmission, the third clutch L3, the electric motor transmission, the fifth clutch L5, and the gearbox, thereby controlling the movement of the emergency vehicle.

[0063] In one embodiment, determining the target clutch among multiple clutches in power mode and operating state includes: when the emergency vehicle is in pure fuel mode and water spraying is performed during driving, the target clutch is the first clutch L1, the third clutch L3, the fourth clutch L4, the fifth clutch L5, the sixth clutch L6, the seventh clutch L7, and the ninth clutch L9, so that the power of the fuel engine is transmitted to the superstructure power take-off, the drive axle, and the water pump power take-off.

[0064] In one embodiment, determining the target clutch among multiple clutches in power mode and operating state includes: when the emergency vehicle is cruising in mains power mode, the target clutches are the second clutch L2 and the fifth clutch L5. Emergency vehicles in locations such as airports have fixed mains power lines, allowing the emergency vehicle to charge during cruising. When the emergency vehicle is in mains power mode, the external power source charges the energy storage module, which powers the main motor. The power from the main motor is then transmitted to the drive axle through the second clutch L2, the motor gearbox, the fifth clutch L5, and the transfer case, enabling the emergency vehicle to complete long-term cruising in mains power mode.

[0065] In one embodiment, determining the target clutch among multiple clutches in power mode and operating state includes: when the emergency vehicle is in mains power mode parking state and performing water spraying operation, the target clutches are the fourth clutch L4, the seventh clutch L7, and the eighth clutch L8.

In addition, the main motor and the secondary motor are connected through the seventh clutch L7, so that the main motor and the secondary motor can complement each other's power, and the emergency vehicle can operate for a long time by connecting to an external power source through the mains power module.

[0066] In one embodiment, the method further includes: when the emergency vehicle is in hybrid mode and switches from a driving state to a temporary parking state, controlling the main motor and fuel engine to shut down, disengaging the ninth clutch L9, and disengaging the first clutch L1, so that the secondary motor provides power to the fuel engine for idling; when the emergency vehicle is in hybrid mode and switches from a temporary parking state to a driving state, controlling the main motor and fuel engine to operate, disengaging the ninth clutch L9, and disengaging the first clutch L1, so that the emergency vehicle can start quickly.
