[0049] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0050] The powertrain system (hybrid system) of a plug-in hybrid electric vehicle mainly consists of an engine, a drive motor, a generator, a reduction gearbox / transmission / planetary gear set, and a clutch. Power is generally transmitted through the transmission / reduction gearbox / planetary gear set. Related hybrid systems generally use a reduction gearbox / planetary gear set or an AMT transmission, and are configured with a dual-motor structure (drive motor and generator) in conjunction with the engine. The drive motor and the engine are switched by a clutch to switch power.

[0051] In related technologies, in order to drive the air conditioner, it is often necessary to equip it with dual motors and also to arrange an independent air conditioning compressor to drive the air conditioner, which makes the structure of the entire hybrid power system more complex, increases the difficulty of arrangement, and increases the cost of the entire structure.

[0052] Example 1

[0053] The first aspect of this application provides an E-AMT transmission driving method, referring to... Figure 1 The driving methods include:

[0054] S1, upon detecting the start signal of the vehicle's air conditioning, obtain the vehicle's current driving mode;

[0055] In hybrid vehicles, there are two drive sources: an electric motor and an engine. In this application, the air compressor of the air conditioning system is not driven by a separate drive source, but is driven by the drive source of the vehicle's power system, which reduces the difficulty of layout and structural cost.

[0056] The hybrid power system consists of five shafts: an engine power shaft connected to the engine body via a clutch; a motor power shaft connected to the motor body; a gear shaft that outputs motor power; a torque-filling shaft equipped with an electric flywheel and synchronizer to fill torque or output motor power; and an output shaft equipped with synchronizer to output power to the wheels. The engine power shaft and the output shaft are connected by multiple sets of gears with different transmission ratios. The gear shaft is connected to the motor power shaft, and the torque-filling shaft is connected to the gear shaft. The torque-filling shaft can be connected to either the engine power shaft or the output shaft. The power input end of the air compressor is connected to the engine power shaft.

[0057] During driving, the air compressor of the air conditioner often relies on one of the drive sources as the main drive source. Therefore, the air compressor needs to be driven by the drive source that is currently providing power. So, it is necessary to obtain the current driving mode of the vehicle, whether it is engine drive mode or electric motor drive mode, in order to determine whether the current drive source used to drive the air compressor is the engine or the electric motor.

[0058] S2, when the vehicle is detected to be in engine drive mode, controls the engine block to drive the engine power shaft to rotate so that the engine block provides power to the air conditioner compressor;

[0059] In this application, in engine drive mode, the engine body is always in a transmission state with the engine power shaft. Therefore, when the current vehicle drive mode is detected to be engine drive mode, power can be directly supplied to the air compressor through the engine body.

[0060] S3, when it detects that the vehicle is in electric motor drive mode, controls the motor body to drive the engine power shaft to rotate so that the engine body provides power to the air conditioning compressor.

[0061] During the electric motor drive process, the motor body is in the starting state, while the engine body may be in the off state, and the engine body is separated from the engine drive shaft. Therefore, when the vehicle is detected to be in electric motor drive mode, the motor body is connected to the engine drive shaft, thereby driving the air conditioner compressor through the motor body to drive the engine drive shaft.

[0062] When passengers activate the air conditioning while the vehicle is in motion, the system detects the vehicle's current drive mode. This includes both engine drive mode (where the engine is running and providing power) and motor drive mode (where the motor is running and providing power). In engine drive mode, the engine is active, and the engine shaft rotates, which in turn drives the air compressor. Similarly, in motor drive mode, the motor drives the engine shaft, which in turn drives the air compressor. This eliminates the need for a separate motor to drive the air compressor, reducing layout complexity and structural costs. Furthermore, it is compatible with hybrid power systems, ensuring that the air compressor can be driven regardless of the vehicle's drive mode, effectively improving the applicability of the entire drive method and device.

[0063] Reference Figure 2 In some embodiments, the driving method further includes:

[0064] S410, acquire the vehicle's drive signals; wherein, the drive signals include engine drive signals and electric motor drive signals;

[0065] During vehicle operation, the vehicle's drive mode is often controlled by the controls on the panel or control panel. Different drive modes are selected and different drive signals are output. When the vehicle detects different drive signals, it is driven to switch to different drive modes.

[0066] S420, upon detecting an engine drive signal, responds to the engine drive signal by controlling the transmission connection between the engine body and the output shaft to put the vehicle into engine drive mode;

[0067] The engine block and the engine drive shaft are connected or disconnected via a dry clutch. When an engine drive signal is detected, it can be assumed that the vehicle needs to be switched to use the engine block as the drive source. Therefore, the clutch between the engine block and the engine drive shaft is closed to allow the power of the engine block to be transmitted to the engine drive shaft, which then drives the wheels to rotate.

[0068] When the S430 detects a motor drive signal, it responds to the motor drive signal by controlling the motor body to drive the output shaft to put the vehicle into motor drive mode.

[0069] The motor body and the motor drive shaft are always connected by transmission. When the vehicle is in engine drive mode, the motor body is usually de-energized. When the motor drive signal is detected, it can be assumed that the vehicle needs to be driven by the motor body as the drive source. The clutch between the engine body and the engine drive shaft is disengaged, and the motor body is powered on, so that power is output through the motor drive shaft.

[0070] Reference Figure 4 In some embodiments, upon detecting a motor drive signal, in response to the motor drive signal, the motor body is controlled to drive the connection between the motor body and the output shaft to put the vehicle into a motor drive mode, including:

[0071] S431, upon detecting a motor drive signal, responds to the motor drive signal by controlling the sequential transmission connection of the motor power shaft, gear shaft, torque filling shaft, engine power shaft, and output shaft.

[0072] The engine power shaft and output shaft are interconnected by five sets of gears with different transmission ratios, enabling five-speed shifting. Therefore, when the vehicle is driven by the motor body, after the clutch between the engine body and the engine power shaft is disengaged, the motor body is connected to the engine power shaft. Specifically, the motor power shaft is connected to the gear shaft to transmit the power of the motor body outward. The gear shaft is connected to the engine power shaft via the torque filling shaft, so that the power of the motor body is transmitted to the output shaft in sequence through the motor power shaft, gear shaft, torque filling shaft, and engine power shaft, forming the path for the power transmission of the motor body.

[0073] S432 controls the main motor to power on, so that the vehicle enters the motor drive mode.

[0074] Once the power transmission path of the motor body is formed, the motor body can be powered on to drive the output shaft to rotate, which in turn drives the wheels to rotate.

[0075] Reference Figure 3 In some embodiments, upon detecting an engine drive signal, in response to the engine drive signal, controlling the engine body to drive the output shaft to engage, thereby putting the vehicle into engine drive mode, includes:

[0076] S421, when an engine drive signal is detected, the engine drive mode corresponding to the engine drive signal is determined; wherein, the engine drive mode includes direct drive mode and torque fill mode;

[0077] Specifically, when the vehicle is in engine drive mode, the engine power shaft is in the shifting period when the vehicle is shifting gears. At this time, there is no torque input to the output shaft, which makes the torque of the wheels easy to be lost. Therefore, in a hybrid system, the output shaft can be filled with torque by the motor body during the shifting period. Therefore, by determining whether the motor body is started, the engine drive mode is divided into direct drive mode when the motor body is not started and torque filling mode when the motor body is started.

[0078] S422, when an engine drive signal corresponding to the direct drive mode is detected, controls the engine body to be connected to the engine drive shaft and controls the motor body to be disconnected from the motor drive shaft so that the vehicle enters the direct drive mode;

[0079] When the engine drive signal in direct drive mode is detected, it can be assumed that the motor body does not participate in the transmission of the entire mechanism. Therefore, the engine power shaft is connected to the output shaft, and the clutch between the engine body and the engine power shaft is closed, so that the output shaft is driven to rotate when the engine body starts, and the vehicle enters direct drive mode.

[0080] At the same time, the control torque filling shaft is connected to the engine power shaft, and the motor body is de-energized, so that the engine power shaft can be driven to rotate by the motor when the engine is off.

[0081] S423, upon detecting the engine drive signal corresponding to the torque fill mode, responds to the engine drive signal by controlling the engine body to be connected to the engine power shaft, and controlling the motor to be connected to the motor power shaft, gear shaft and torque fill shaft in sequence, so as to put the vehicle into torque fill mode.

[0082] When the engine drive signal corresponding to the torque filling mode is detected, it can be assumed that the motor body participates in the transmission of the entire mechanism, but the engine body is still regarded as the main power source. Therefore, the engine power shaft is controlled to be connected to the output shaft, and the clutch between the engine body and the engine power shaft is closed, so as to drive the output shaft to rotate when the engine body starts.

[0083] At the same time, the torque filling shaft is connected to the output shaft so that the motor power shaft, gear shaft and torque filling shaft are connected in sequence to form a power transmission path, so that the vehicle enters the torque filling mode. When the motor body starts, it can input torque to the output shaft.

[0084] Reference Figure 5 In some embodiments, the driving method further includes:

[0085] S510 acquires the vehicle's shift signal when it detects that the vehicle is in torque fill mode;

[0086] During vehicle operation, when the clutch pedal is depressed, it is assumed that the vehicle needs to shift gears. Therefore, the vehicle is controlled to enter the shifting state. At this time, the output shaft torque input is missing, so the vehicle outputs a shift signal to start shifting gears, so that the vehicle enters the torque filling mode, and the output shaft is filled with torque through the motor body during the shifting process.

[0087] When a shift signal is detected, the S520 controls the engine power shaft to separate from the output shaft in response to the shift signal, and controls the engine body to drive the output shaft to rotate in sequence through the motor power shaft, gear shaft and torque filling shaft, so as to provide torque to the output shaft during the shift process.

[0088] After detecting a shift signal, the clutch between the engine drive shaft and the engine block is disengaged, disconnecting the power transmission between the engine block and the output shaft. At this time, since the vehicle is in torque filling mode, the torque filling shaft is connected to the output shaft. Therefore, the motor body is started, thereby supplementing torque through the motor drive shaft, gear shaft, and torque filling shaft to the output shaft. This eliminates the torque loss present in the direct drive mode while driving the vehicle, thus improving the shift quality. At the same time, the motor body drives the engine drive shaft to continue rotating so that the air compressor of the air conditioner can continue to work.

[0089] Reference Figure 6 In some embodiments, the driving method further includes:

[0090] S610, when it detects that the vehicle is in a turned-off state, obtains the drive mode before the vehicle was turned off; the drive mode includes direct drive mode, torque fill mode and electric motor drive mode.

[0091] After the vehicle is turned off, the engine is shut off. When the air conditioner is turned on, the air compressor is usually driven by the motor. Therefore, it is necessary to detect the driving mode of the vehicle before it was turned off to determine the torque transmission path when the motor is driving.

[0092] S620, when it detects that the driving mode before the vehicle is turned off is direct drive mode or electric motor drive mode, controls the main body of the motor to be connected to the motor power shaft, gear shaft, torque filling shaft and engine power shaft in sequence, so as to drive the engine power shaft to provide power to the air conditioner compressor;

[0093] When the vehicle is in direct drive mode or electric motor drive mode before being turned off, the power transmission path is sequentially: electric motor power shaft, gear shaft, torque filling shaft, engine power shaft, and output shaft. Since the air compressor of the air conditioner is driven by the engine power shaft, the motor body drives the electric motor power shaft to rotate, which in turn drives the electric motor air compressor to work through the gear shaft, torque filling shaft, and engine power shaft.

[0094] When the S630 detects that the drive mode before the vehicle is turned off is torque fill mode, the main body of the motor is sequentially connected to the motor power shaft, gear shaft, torque fill shaft, output shaft and engine power shaft to drive the engine power shaft to provide power to the air conditioner compressor.

[0095] When the vehicle is off and in torque filling mode, the torque filling shaft is connected to the output shaft. At this time, the torque transmission route of the motor body is the motor power shaft, gear shaft, torque filling shaft and output shaft. Therefore, the torque is transmitted to the engine power shaft through the output shaft to drive the engine power shaft to rotate. There is a set of gears meshing between the engine power shaft and the output shaft, regardless of which of the five gears is in, so that the engine power shaft always has torque input.

[0096] In some specific embodiments, when the vehicle is in torque filling mode and is turned off, the engine power shaft and the output shaft are driven by a gear set with the smallest transmission ratio to ensure that the engine power shaft is at a large speed when the output shaft inputs torque to the engine power shaft, thus meeting the drive requirements of the air compressor.

[0108] When the vehicle air conditioning start signal is detected by module 71, the current driving mode of the vehicle is obtained.

[0116] When the first control module 72 detects the engine drive signal corresponding to the direct drive mode, it controls the engine body to be connected to the engine power shaft and controls the motor body to be de-energized, so that the vehicle enters the direct drive mode.

[0117] When the first control module 72 detects the engine drive signal corresponding to the torque filling mode, it responds to the engine drive signal by controlling the engine body to power on and controlling the transmission connection of the motor power shaft, gear shaft and torque filling shaft to enable the vehicle to enter the torque filling mode.

[0119] The shift module 74 is used to acquire the vehicle's shift signal when the vehicle is detected to be in torque fill mode;

[0120] The torque filling module 75 is used to control the engine power shaft to separate from the output shaft in response to the shift signal when a shift signal is detected, and to control the engine body to drive the output shaft to rotate in sequence through the motor power shaft, gear shaft and torque filling shaft, so as to provide torque to the output shaft during the shift process.

[0121] In some embodiments, the drive device further includes a flameout control module 76 for implementing the following steps:

[0122] When the acquisition module 71 detects that the vehicle is in a turned-off state, it acquires the driving mode of the vehicle before it was turned off; wherein, the driving mode includes direct drive mode, torque filling mode and motor drive mode.

[0123] When the engine shutdown control module 76 detects that the driving mode of the vehicle before engine shutdown is the direct drive mode or the motor drive mode, it controls the motor body to be connected to the motor power shaft, gear shaft, torque filling shaft and engine power shaft in sequence, so as to drive the engine power shaft to provide power to the air conditioner compressor.

[0124] When the engine shutdown control module 76 detects that the driving mode before the vehicle is turned off is the torque filling mode, the motor body is sequentially connected to the motor power shaft, the gear shaft, the torque filling shaft, the torque output shaft and the engine power shaft to drive the engine power shaft to provide power to the air conditioner compressor.
