The first clutch is engageable under the control of the hybrid control unit to connect the engine output shaft with the first carrier as one piece when needed. The first brake is capable of braking under the control of the hybrid control unit to fix the first carrier when needed. Thus, with the first clutch engaged, the first electric machine can be operated to start the engine, and after the engine is started, the first electric machine can be shifted to the generation mode again to charge the power battery.

The second motor is a permanent magnet brushless direct current motor, is a main driving motor for driving wheels, can also be used as a generator for charging a power battery, and can also work in combination with the first motor to start the engine at proper time. The motor is controlled by a frequency converter, and the direction and the rotating speed of the motor are controlled by controlling the phase sequence and the frequency. Meanwhile, the motor feeds back technical parameters such as rotor position, motor temperature and the like to the hybrid power control unit, so that the hybrid power control unit controls the motor through the frequency converter, and a protection mode can be started if necessary.
The frequency converter is also respectively connected with the hybrid power control unit and the power battery. The engine is connected with the hybrid power control unit through an engine control unit.
In addition to the control connection of the hybrid control unit, the connection manner of the power battery as the power output is as follows: the input end of the charging device is connected with the charging interface; the first output end of the power battery is connected with the frequency converter to provide a working power supply for the frequency converter, and meanwhile, the electric quantity information is fed back to the frequency converter; and a second output end of the power battery is connected with an auxiliary storage battery through a DC/DC converter.

And a third output end of the auxiliary storage battery is connected with the frequency converter.
Based on the above-mentioned connection mode of the transmission system, the working state of the hybrid electric vehicle of the present invention is mainly divided into the following cases: the method comprises the following steps of (1) starting working conditions, (2) low-speed small-load working conditions, (3) medium-high-speed large-load working conditions and (4) rapid deceleration braking overspeed working conditions during forward running.
Starting condition
(1) The starting working condition is pure electric driving starting, and the specific working mode is as follows. The engine and the first motor do not work, the first clutch, the second clutch and the third clutch are all in a separation state, the first brake and the second brake do not brake, and the third brake brakes the gear ring of the second planetary gear. When the forward gear is engaged, the second motor rotates forward to drive the automobile to start and drive; when the reverse gear is engaged, the second motor reversely drives the automobile to start and reverse.
(2) The low-speed small-load working condition is further divided into two working conditions of (201) sufficient power battery and (202) insufficient power battery.
(201) The specific working mode of the power battery with sufficient electric quantity is as follows. (201a) If the pure electric driving is the independent driving of the second motor, the mode is the same as the starting working condition. (201b) If the pure electric driving is in a common driving mode of the first motor and the second motor: the first clutch and the second clutch are in a separated state, the third clutch is in an engaged state, the first brake and the third brake are in a braking state, and the second brake does not brake. The forward or reverse running is determined by the forward or reverse rotation of the motor, and the reverse rotation of the motor is performed when the motor is forward rotated or reverse rotated when the motor is forward rotated.
(202) The specific working mode of the power battery with insufficient electric quantity is as follows. (202a) When the vehicle is driven forward, the first clutch and the third clutch are in an engaged state, the second clutch is in a disengaged state, the third brake is in a braking state, the first brake and the second brake are not braked, and the first motor and the second motor work together to start the engine timely. After the engine is started, the second brake is turned into a braking state, the engine drives wheels to operate, the first motor does not work, the working state of the second motor is turned into a power generation mode, and redundant power of the engine charges a power battery through the second motor.
(202b) When the vehicle is running in reverse, if the power battery is not seriously deficient, the running mode is the same as the mode when the power battery is sufficient (201). If the power battery is seriously deficient, the instrument can display that the battery is seriously deficient, the first clutch and the second clutch are in an engaged state, the third clutch is in a separated state, the first brake, the second brake and the third brake are not braked, and the first motor rotates positively to start the engine to work; after the engine is started, the working state of the first motor is changed into a power generation mode, and the power battery is charged. When the power battery reaches a certain level, the vehicle enters a reversing running state, and the running mode during reversing is the same as the mode when the power battery is full (201).
(3) The specific working mode of the medium-high speed and large load working condition is as follows. This condition is only used for forward travel conditions. The first clutch and the third clutch are in an engaged state, the second clutch is in a disengaged state, the third brake is in a braking state, the first brake and the second brake are not braked, and the first motor and the second motor work together to start the engine timely. After the engine is started, the second brake is turned into a braking state, the first motor does not work, the engine drives wheels to run, the second motor is turned into a generator, and the surplus energy of the engine charges the power battery through the second motor.
(4) The specific working modes of the rapid deceleration, braking and overspeed working conditions during forward running are as follows. When the vehicle speed exceeds the set maximum speed, the system working mode is automatically converted into an energy recovery mode, at the moment, the engine does not work, the first clutch and the second clutch are in a separation state, the third clutch is in an engagement state, the first brake and the third brake are in a braking state, the second brake is not braked, the first motor and the second motor are converted into a power generation state, the vehicle kinetic energy is converted into electric energy, the power battery is charged, and the energy recovery is carried out.
Besides the working condition when the vehicle moves, the transmission system is also suitable for the working condition when the vehicle is stationary. Such as (5) engine service or debug conditions, and (6) charging conditions.
In the overhauling or debugging state of the engine, the gear switch is arranged in the neutral gear. If the engine does not need to be started, the engine auxiliary control switch is positioned at the ignition position, the engine control unit enters a working state, related instruments such as a universal meter and the like can be used for detecting the engine, and at the moment, the ignition switch does not need to be closed. If the engine needs to be started, the ignition switch is closed, when the engine auxiliary control switch is in a starting position, the hybrid power control unit controls the first clutch and the second clutch to be connected, the third clutch is separated, the first brake, the second brake and the third brake are not braked, the first motor rotates positively, and the engine is started to run. After the engine is started, the engine auxiliary control switch is returned to the ignition position, at the moment, all clutches are separated, and all brakes are not braked, so that the engine can be overhauled or debugged.
And (3) when the battery (6) is charged, the charging interface can be externally connected with 220V alternating current to charge the power battery.
In summary, the present invention has a first planetary row with a dual stage planetary gear mechanism and a second planetary row with a single stage planetary gear mechanism, both of which construct power transfer between the engine, the first motor, and the second motor under different conditions. Further, the first carrier and the first sun gear of the first row of satellites are connected by the second clutch, so that the first carrier is connected with the first sun gear as a single body when necessary. Therefore, each specially arranged clutch and brake on the planet row ensures smooth switching between different working conditions and stable operation under the same working condition. The system has the advantages of energy conservation and environmental protection by the connection mode among the components and the switching mode of different working conditions. The system has simple structure and no transmission arranged independently, but can realize the function of stepless speed change. The engine control unit and the hybrid power control unit can cooperate with each other to realize the optimal optimization of the working mode.
