Besides that the battery technology is not mature enough, the related engines belong to internal combustion engines, and the fact that the internal combustion engines have low thermal efficiency is also recognized by the public, so that the improvement of the thermal efficiency of the engines is also the focus of research.

Description of the drawings:

FIG. 1 is a schematic structural diagram of a parallel impeller-cylinder combined hybrid electric vehicle;

FIG. 2 is a schematic structural diagram of a series-parallel impeller-cylinder combined hybrid electric vehicle;

the specific implementation mode is as follows:

in fig. 1, a flywheel 2 is provided at the right end of an impeller-cylinder combination engine 1. The flywheel 2 is connected to a motor 3 via a hydraulic automatic clutch 4 and an intermediate plate 5. The motor 3 is communicated with a power battery 8 through a motor controller 7. The right end of the intermediate disk 5 is respectively provided with a mechanical clutch 6 and a transmission 9, and the transmission 9 and a differential 10 are in loose joint.

In fig. 2, the impeller cylinder combination engine 1 is movably connected with the generator 11 and communicated with the power battery 8. The power battery 8 is communicated with the motor controller 7 and the motor 3 respectively. The impeller cylinder combination engine 1 and the electric motor 3 are respectively movably connected with the ECVT transmission 12.

1. Five working modes of the parallel impeller cylinder combined hybrid electric vehicle are as follows:

1. electric only mode

In the starting stage and the low-speed running state of the vehicle, in the figure 1, the impeller cylinder combined engine 1 does not work, the hydraulic automatic clutch 4 and the intermediate plate 5 are in a separated state, the mechanical clutch 6 and the intermediate plate 5 are combined, the whole vehicle drive is completely powered by the power battery 8, and then the current regulated by the motor controller 7 drives the motor 3 to run. The running electric motor 3 drives the intermediate disk 5 and the mechanical clutch 6 to run at the same time, and drives the vehicle to run through speed regulation of the speed changer 9 and the differential mechanism 10.

2. Engine drive mode

When the vehicle is cruising at a high speed, in fig. 1, the power output by the vane-cylinder combined engine 1 is output to the electric motor in excess of the power required for the vehicle to travel. At this time, the hydraulic automatic clutch 4 and the mechanical clutch 6 are simultaneously coupled to the intermediate disk 5, and the power output from the vane-cylinder combination engine 1 is driven by the flywheel 2, the hydraulic automatic clutch 4, the intermediate disk 5, the mechanical clutch 6, the transmission 9, and the differential 10. On the other hand, the impeller-cylinder combined engine 1 transmits power to the motor 3 through the flywheel 2, the hydraulic automatic clutch 4 and the intermediate disc 5 to generate electricity, and the current generated by the motor 3 is stored in the power battery 8 after being regulated by the motor controller 7.

3. Engine and electric motor hybrid drive mode

When the vehicle accelerates or climbs a slope, in fig. 1, the output power of the motor 3 cannot meet the requirement of the whole vehicle. The impeller cylinder combination engine 1 is started, and when the rotating speed of the impeller cylinder combination engine 1 is the same as that of the electric motor 3, the hydraulic automatic clutch 4 and the mechanical clutch 6 are simultaneously combined with the intermediate plate 5. The current released by the power battery 8 is regulated by the motor controller 7 to drive the motor 3 to run, the torque of the impeller cylinder combined engine 1 and the torque of the motor 3 are superposed, and the motor are driven to run by the hydraulic automatic clutch 4, the intermediate disc 5, the mechanical clutch 6, the transmission 9 and the differential mechanism 10.

4. Idle charge mode

In fig. 1, when the control system determines that the remaining power in the power battery 8 is not sufficient to drive the vehicle to start by the motor 3 when the vehicle stops, the idle charging mode is automatically entered, and the vehicle stops and the vehicle speed is zero. The hydraulic automatic clutch 4 is combined with the intermediate disc 5, the mechanical clutch 6 is separated from the intermediate disc 5, the impeller-cylinder combined engine 1 respectively drives the flywheel, the hydraulic automatic clutch 4 and the intermediate disc 5 to operate and drives the motor 3 to generate current, and the current is stored in the power battery 8 after being regulated by the motor controller 7.

5. Braking energy recovery mode

When the vehicle has a certain speed, the driver releases the accelerator pedal, and the vehicle enters a coasting mode. In fig. 1, the vane cylinder combination engine 1 is stopped, the hydraulic automatic clutch 4 and the intermediate plate 5 are disengaged, the mechanical clutch 6 and the intermediate plate 5 are engaged, the inertial force of the vehicle drives the electric motor 3 to generate electricity through the differential 10, the transmission 9, the mechanical clutch 6 and the intermediate plate 5, and the electric motor 3 operates in a generator mode. The current generated by the motor 3 is regulated by the motor controller 7 and stored in the power battery 8 for standby.

2. The four working modes of the series-parallel impeller cylinder combined hybrid electric vehicle are as follows:

the mode does not have a traditional gearbox, and the traditional gearbox is usually replaced by a coupling unit gearbox with an ECVT planetary gear structure, so that the modes play roles in connecting and switching two kinds of power, reducing speed and increasing torque. The hybrid structure can drive the engine to charge the power battery when the impeller cylinder combined engine and the motor cooperatively drive the vehicle to run, and does not need to provide two functions for a single motor in the parallel structure, so that the mode that the impeller cylinder combined engine drives the generator to generate power and the motor drives the vehicle can be realized.

1. Pure electric mode:

when the vehicle runs at a low speed, a pure electric mode is used, in fig. 2, the impeller cylinder combination engine 1 is turned off, the current output by the power battery 8 is regulated by the motor controller 7, then the motor 3 is started to run, and the output power drives the vehicle to run under the regulation and control of the ECVT transmission 12.

2. Pure oil mode

In this mode, in fig. 2, the vane-cylinder combined engine 1 is started and drives the ECVT transmission 12 to regulate the running of the vehicle, and at the same time, the vane-cylinder combined engine 1 also drives the generator 11 to charge the power battery 8.

3. Mixed mode

When the vehicle runs on a slope or runs at a rapid acceleration, in fig. 2, the impeller cylinder combined engine 1 drives the ECVT transmission 12 to regulate and control the vehicle to run, and at the same time, the current output by the power battery 8 is regulated by the motor controller 7 and then drives the motor 3 to run. The power output by the electric motor 3 is regulated and controlled by the ECVT transmission 12 to synchronously assist the vehicle to run.

4. Charging mode

In the charging mode, the vane-cylinder combined engine 1 does not drive the vehicle to run in fig. 2. The impeller cylinder combined engine 1 drives the generator 11 to generate electricity and charge the power battery 8. At the moment, the power battery 8 supplies power to the electric motor 3 through the motor controller 7 and starts to operate, and the power output by the electric motor 3 is regulated and controlled by the ECVT transmission 12 to drive the vehicle to run. In this case, the vehicle is driven by an electric motor, which corresponds to a vehicle having a tandem structure.

The characteristics and the use advantages of the series-parallel structure are closer to those of parallel vehicle types, but the series-parallel driving mode is richer, and the charging function is added on the basis of the parallel hybrid driving mode, so that the problem of electric quantity consumption is not needed to be considered when the engine and the motor drive the vehicle in a full-force manner, and the cooperation of the motor and the engine is better understood due to the addition of the ECVT, so that the working condition capable of adapting to is more, and the energy-saving effect is better.
