Description
技术领域Technical field

At the same time, due to the bottleneck constraints of the key technologies of pure electric vehicles and fuel cell vehicles, hybrid electric vehicles have become a timely choice. Facts have also proved that This choice can achieve more satisfactory results. The research and development of electric vehicles involves many key technologies, including batteries, high-performance motors, power synthesis and control technology, integrated engine control, etc. However, all these research objects are realized with a good transmission system as the research object, so the choice of power synthesis method and structural method is directly related to the positioning of the target car.
现有技术中的一种混合动力变速器驱动系统，是在对变速器改动最小的前提下通过在变速器上添加一个电动机形成的。电动机通过固定速比减速机构或者两挡变速机构与主减速器被动齿轮相连接，从而避免对变速输出轴之前的零部件进行修改，确保了最大程度地利用现有变速器的主要零部件。但这种混合动力变速器驱动系统存在一个功能性缺陷，即驻车时电动机不能被发动机驱动发电，因此难以保证蓄电装置的电量平衡。A hybrid transmission drive system in the prior art is formed by adding an electric motor to the transmission with minimal modifications to the transmission.

4、车辆启动时，离合器处于分离状态，以主驱动电机进行驱动，驱动车辆至发动机可在高效经济区工作的车速时，辅助电机预先启动发动机并使其在高效经济区车速中介入驱动，实现并联混动，并可逐渐代替主驱动电机驱动，可极大地降低油耗，大大地节省成本；4. When the vehicle starts, the clutch is in a disengaged state, and the main drive motor is used to drive the vehicle to a speed where the engine can work in the high-efficiency economic zone. The auxiliary motor starts the engine in advance and makes it intervene in the drive at the speed of the high-efficiency economic zone, realizing Parallel hybrid can gradually replace the main drive motor drive, which can greatly reduce fuel consumption and save costs;
5、在发动机换挡过程中主驱动电机补充动力差值保证系统换挡时动力不中断，提升驾驶的舒适性；5. During the engine shifting process, the main drive motor supplements the power difference to ensure that the power is not interrupted when the system shifts gears, improving driving comfort;
6、将传统意义上的倒挡去掉，通过主驱动电机倒转即可实现倒挡；6. Remove the reverse gear in the traditional sense and realize the reverse gear by reversing the main drive motor;
7、在主驱动电机单独工作的情况下，如电池包电量低于一定的设定值，辅助电机启动发动机，发动机启动至高效经济区通过辅助电机发电直接驱动主动电机或为电池包充电，当停车状态下发动为电池包补充电量；7. When the main drive motor works alone, if the battery pack power is lower than a certain set value, the auxiliary motor starts the engine. The engine starts to the high-efficiency economic zone and uses the auxiliary motor to generate electricity to directly drive the active motor or charge the battery pack. Start when parking to replenish the battery pack;
8、车辆制动时，通过主驱动电机进行回收能量，避免能量的浪费；8. When the vehicle is braking, energy is recovered through the main drive motor to avoid energy waste;
9、发动机可在任一挡位上均可工作，实现较大范围的介入，适用于更多复杂的工况；9. The engine can work in any gear, achieving a wider range of intervention and suitable for more complex working conditions;
10、辅助电机在发动机并联介入系统工作时，可产生负载使发动机尽量逼近高校区工作，且产生的负载可用于发电，更节能；10. When the engine is connected in parallel to the system, the auxiliary motor can generate a load to make the engine work as close to the university campus as possible, and the generated load can be used for power generation, which is more energy-saving;
11、第二实施例、第四实施例和第六实施例能够在纯电动工况下行驶，挡位有两挡选择，可根据需要进行挡位切换，以降低对主驱动电机的要求。另外，本系统在单发动机工况下行驶时，E同步器不挂挡，主驱动电机不会被“拖曳”，主驱动电机转子就不会转动、不会产生转动惯量，并不会对换挡产生影响，消除冲击感，整车不会抖动，驾乘舒适性较好；11. The second embodiment, the fourth embodiment and the sixth embodiment can drive under pure electric conditions. There are two gears to choose from. The gears can be switched as needed to reduce the requirements on the main drive motor. In addition, when this system is driving under single-engine operating conditions, the E synchronizer is not in gear, the main drive motor will not be "dragged", the main drive motor rotor will not rotate, will not generate rotational inertia, and will not reverse The impact is caused by the gear shifting, eliminating the impact feeling, the whole vehicle will not shake, and the driving comfort is better;
12、本系统更紧凑，重量轻、体积小，有利于整车搭载。12. This system is more compact, light in weight and small in size, which is beneficial to the whole vehicle.
