5 The double-motor double-planet-row multi-mode electromechanical coupling driving device in the present application can realize the following operating modes. (1) Pure electric 1-gear mode (EV 1): the first clutch C1 is engaged, the first brake B1 is engaged to brake, and the second brake B2 is disengaged. The first motor E1 individually drives a vehicle to run or double motors of the first motor El and the second motor E2 jointly drive the vehicle to run. The engine does not run. In the mode, the reverse gear can be realized by the reversal of the two motors. (2) Pure electric 2-gear mode (EV2): the first clutch C1 is disengaged; the first brake Bl is engaged to brake (under the drive of double motors of the first motor El and the second motor E2) or is loaded (under the individual drive of the first motor E1); and the second brake B2 is engaged. The first motor E1 individually drives a vehicle to run or double motors of the first motor Et and the second motor E2 jointly drive the vehicle to run. The engine does not run. In the mode, the reverse gear can be realized by the reversal of the two motors. (3) Low speed hybrid mode (HEV 1}: the first clutch C1 is disengaged, the first brake B1 is disengaged (the first rotating shaft 1 conducts transcending rotation), and the second brake B2 is engaged. The first motor El outputs power to drive the vehicle to run, and the second motor E2 generates electricity. The output power of the engine is split in the first planetary gear set; part of the power Is transmitted to a wheel end to drive the vehicle to run, and part of the power is transmitted to the second motor E2 to drive the second motor E2 to generate electricity, i.e., input power split. In the mode, the second motor E2 can realize stepless speed regulation for the engine, that is, the mode is eCVT mode. (4) Fixed speed ratio mode 1 (FR): the first clutch C1 is engaged, the first brake Bl is disengaged (the first rotating shaft I conducts transcending rotation), and the second brake B2 is engaged. At this moment, the speed ratio of the first rotating shaft 1 and the second rotating shaft 2 which are connected with the engine is fixed. The rotational speed of the second motor E2 is 0, and power output or electricity generation is not
6 AO 21.08.1095 NL conducted. The output power of the engine can be fully used to drive the vehicle to run, or partially used to drive the vehicle to ran and partially used to drive the first motor El to generate electricity. The first motor E1 can also be combined with the engine to drive the vehicle to run. In the fixed speed ratio mode, the speed ratio of the first rotating shaft 1 and the fourth rotating shaft 4 is less than 1.
(5) High speed hybrid mode (HEV2): the first clutch C1 is engaged, the first brake Bl is disengaged (the first rotating shaft 1 conducts transcending rotation), and the second brake B2 is disengaged. At this moment, the engine, the first motor E1 and the second motor E2 can realize four-axis compound power split. Part of the output power of the engine drives the vehicle to run, and part of the output power generates electricity through the second motor E2. The first motor El outputs power to drive the vehicle to run. In the mode, with the permission of the output of a battery pack and the power of a motor controller, the engine, the first motor El and the second motor E2 can also be combined with the output power to drive the vehicle to run. At this moment, the rotational speed of the engine can be subjected to continuous stepless regulation by the first motor E1 or the second motor E2, which is also the eCVT mode. (6) Engine start mode: in the solution of the present invention, the second motor E2 can directly output a torque to start the engine. (7) Parking power generation mode: when the vehicle is in a parking state, the seventh rotating shaft 7 or the fourth rotating shaft 4 of the structure is locked through a parking locking mechanism, and the second brake B2 and the first brake B1 are disengaged. The output power of the engine is transmitted to the second motor E2 through a first planet row to generate electricity and charge the battery pack. If the first clutch C1 is engaged, part of the output power of the engine can be continuously transmitted to the first motor El through a second planet row, i.e., the first motor El and the second motor E2 can simultaneously generate electricity and charge the battery pack. (8) Braking energy recovery mode: when the vehicle goes downhill or brakes, the reduced kinetic energy is transmitted to the first motor E1 through the second planet row; the first motor E1 outputs a braking torque to generate electricity and charge the battery pack; and if the first clatch C1 is engaged, the second motor E2 can be combined with the first motor El to output the braking torque to generate electricity and charge the battery pack.
7 AO 21.08.1095 NL Specifically, the first brake B1 is a unidirectional brake. Specifically, the second brake B2 is a wet multi-disc brake. Specifically, the first clutch C1 is a wet multi-disc clutch. It should be noted that, in the solution of the present invention, the structural forms of the first brake Bl, the second brake B2 and the first clutch C1 are not limited to the unidirectional brake/clutch and the wet multi-disc clutch/brake described herein.
