该并联式动力系统具有如下八种工作模式:
1、整车控制器通过CAN-BUS网络对电池管理系统BMS、电机控制器发出相应的指令,电机接受到三项交流电旋转起来,与此同时,阀2通过相应的液压回路,使得离合器C2结合,电机运转的同时带动发动机从静止时刻开始运动,进行冷起动;
2、当汽车静止不动,发动机控制器ECU控制发动机CE运转,同时阀2通过相应的液压回路,使得离合器C2结合,整车控制器通过CAN-BUS网络对电池管理系统BMS、电机控制器发出相应的指令,电机此时作为发电机运转,逆向对动力电池进行充电,储备电源;
3、动力电池电量充足,车辆在停停走走的交通环境或有交通信号灯控制的情况下,在车辆不行驶期间,整车控制器通过CAN-BUS网络协调管理发动机管理系统,发动机熄火,同时阀2通过相应的液压回路,使得离合器C2分离;
4、动力电池电量充足,整车控制器通过CAN-BUS网络对电池管理系统BMS、电机控制器发出相应的指令,电机接受到三项交流电旋转起来,发动机控制单元发出相应的指令,发动机熄火,与此同时,阀2通过相应的液压回路,使得离合器C2分离,阀1通过相应的液压回路,使得离合器C1分离;之后,电机运转,通过阀1控制离合器C1离合状态,进行冷起动电动起步或机动行驶;
5、在较高的行驶速度时,整车控制器通过CAN-BUS网络对电池管理系统BMS、电机控制器发出相应的指令,电机接受到三项交流电旋转起来,发动机控制单元发出相应的指令,使发动机点火喷油运转,与此同时,阀2通过相应的液压回路,使得离合器C2打滑,电机运转,进行高速起动发动机;
6、当发动机转速同步后,阀2通过相应的液压回路,使得离合器C2打滑减轻,与此同时,阀1通过相应的液压回路,使得离合器C1结合,整车控制器通过CAN-BUS网络对电池管理系统BMS、电机控制器发出相应的指令,电机逐渐停止转动,发动机控制单元发出相应的指令,使发动机运转单独驱动变速器工作;
7、在汽车滑行状态下,整车控制器通过CAN-BUS网络对电池管理系统BMS、电机控制器发出相应的指令,电机实现发电运转,通过电机控制器逆向传递,使得滑行功能就会转变成电能并临时存储在动力电池中,同时阀2通过相应的液压回路,使得离合器C2结合,阀1通过相应的液压回路,使得离合器C1结合;制动时,在功率水平较高的情况下,可以回收电能;
8、在滑行情况下或者在制动时,阀2通过相应的液压回路,使得离合器C2分离,阀1通过相应的液压回路,使得离合器C1结合,从而使发动机及其阻力矩解耦关闭,使发动机机不必被拖带着运转,整车控制器通过CAN-BUS网络对电池管理系统BMS,电机控制器发出相应的指令,电机实现发电运转,通过电机控制器逆向传递,使得滑行功能就会转变成电能并临时存储在动力电池中,这样提高了动能转换成电能的效率。
本发明的优点和有益效果为:
本发明的并联式动力系统采用一台电机与两个离合器C1和C2替代了液力变矩器钟型壳内的液力变矩器,并且还起到了起步元件的功能;由于电机通过离合器C1与变速器输入轴连接,电动机能利用传动比进行特性转换(像内燃机一样),并且在功率和转矩需求变化的情况下能够完成驱动和发电功能;同时这种布置方案和传统式自动变速器占用相同的空间。

4、动力电池电量充足,整车控制器通过CAN-BUS网络对电池管理系统BMS、电机控制器发出相应的指令,电机接受到三项交流电旋转起来,发动机控制单元发出相应的指令,发动机熄火,与此同时,阀2通过相应的液压回路,使得离合器C2分离,阀1通过相应的液压回路,使得离合器C1分离;之后,电机运转,通过阀1控制离合器C1离合状态,进行冷起动电动起步或机动行驶;
5、在较高的行驶速度时,整车控制器通过CAN-BUS网络对电池管理系统BMS、电机控制器发出相应的指令,电机接受到三项交流电旋转起来,发动机控制单元发出相应的指令,使发动机点火喷油运转,与此同时,阀2通过相应的液压回路,使得离合器C2打滑,电机运转,进行高速起动发动机;
6、当发动机转速同步后,阀2通过相应的液压回路,使得离合器C2打滑减轻,与此同时,阀1通过相应的液压回路,使得离合器C1结合,整车控制器通过CAN-BUS网络对电池管理系统BMS、电机控制器发出相应的指令,电机逐渐停止转动,发动机控制单元发出相应的指令,使发动机运转单独驱动变速器工作;
7、在汽车滑行状态下,整车控制器通过CAN-BUS网络对电池管理系统BMS、电机控制器发出相应的指令,电机实现发电运转,通过电机控制器逆向传递,使得滑行功能就会转变成电能并临时存储在动力电池中,同时阀2通过相应的液压回路,使得离合器C2结合,阀1通过相应的液压回路,使得离合器C1结合;制动时,在功率水平较高的情况下,可以回收电能;
8、在滑行情况下或者在制动时,阀2通过相应的液压回路,使得离合器C2分离,阀1通过相应的液压回路,使得离合器C1结合,从而使发动机及其阻力矩解耦关闭,使发动机机不必被拖带着运转,整车控制器通过CAN-BUS网络对电池管理系统BMS,电机控制器发出相应的指令,电机实现发电运转,通过电机控制器逆向传递,使得滑行功能就会转变成电能并临时存储在动力电池中,这样提高了动能转换成电能的效率。
