Embodiment 1

[0029] Such as figure 1 Shown, a kind of gasoline-electric hybrid multi-mode vehicle drive system, mainly by engine (1), ISG motor (21), hub motor (22) and (23), clutch (31) and (32), overrunning clutch (41 ) and (42), control unit ECU (5), battery pack (6), motor controller (7), wheels (81) and (82), multiple rotational speed sensors (91), (92), (93) , (94), (95) and power transmission shaft (10) etc. are formed.

[0030] One end of the rotor of the ISG motor (21) is connected to the output end of the engine (1) through the clutch (31), and the other end is respectively connected to one end of the overrunning clutches (41) and (42) through the clutch (32) and the transmission shaft (10). The other end of clutch (41), (42) is then connected with wheel (81), (82) respectively; Hub motor (22) and (23) are installed in the wheel (81), (82) respectively, can directly drive vehicle . The control unit ECU (5) sends instructions to clutches (31) and (32), overrunning clutches (41)...

Embodiment example 2

[0054] Such as figure 2 Shown, a kind of gasoline-electric hybrid multi-mode vehicle drive system, mainly by engine (1), ISG motor (21), hub motor (22) and (23), clutch (31), overrunning clutch (41) and (42 ), control unit ECU (5), battery pack (6), motor controller (7), wheels (81) and (82) and multiple rotational speed sensors (91), (92), (93), (94) , (95) and so on.

[0055] Its difference with Embodiment 1 is that the clutch (32) has been removed. The difference between the various working modes of the hybrid electric vehicle and Embodiment 1 lies in the electric starting mode: when the vehicle starts, the ISG motor (5) and the transmission shaft (10) omit the connection of the clutch, and the ISG motor (5) ) is directly connected with the drive shaft (10), and the ISG motor (5) no longer functions as a starter.

[0056] In the hybrid drive mode, the pure engine drive mode, the pure electric drive mode, the regenerative braking mode and the reverse mode, the working pr...

Embodiment approach 3

[0058] Such as image 3 Shown, a kind of gasoline-electric hybrid multi-mode vehicle drive system, mainly by engine (1), ISG motor (21), hub motor (22) and (23), clutch (32), overrunning clutch (41) and (42 ), control unit ECU (5), battery pack (6), motor controller (7), wheels (81) and (82) and multiple rotational speed sensors (91), (92), (93), (94) , (95) and so on.

[0059] It differs from Embodiment 1 in that the clutch (31) is removed, and the engine (1) is directly connected to the rotor shaft of the ISG motor (5). The various modes of operation of this scheme hybrid electric vehicle are different from embodiment 1 in that:

[0060] ●Pure electric drive mode

[0061] Since the engine (1) is directly connected to the ISG motor (5) rotor shaft, both always have the same rotational speed. Therefore, if the vehicle is to run in pure electric mode, the vehicle can only be powered by the hub motor (22) and the hub motor (23), and at this time, the clutch (32) is in a dise...

Abstract

The invention discloses an oil-electricity hybrid multi-mode automobile drive system. The system is mainly composed of an engine, two clutches, an ISG motor, two overrun clutches, two hub motors, a control unit ECU, a motor controller, a storage battery group and the like. The two ends of an ISG motor rotor are connected with the output end of the engine and a transmission shaft through the first clutch and the second clutch respectively. The two ends of each overrun clutch are connected with the transmission shaft and a corresponding wheel. The wheels are internally provided with the hub motors which can directly drive a vehicle to run. The control unit ECU sends an instruction to the clutches and the motor controller according to signals fed back by a sensor so that the combining/separating of the clutches and power output of the motor can be controlled and the purpose of work mode switching can be achieved. By means of the multi-mode character of the system, the opportunity of working at an efficient range is increased for the engine; and by means of the overrun clutches, the differential function under certain modes can be achieved, the energy consumption of additional loads can also be reduced, and the system efficiency can be improved.

Description

technical field [0001] The invention relates to an automobile drive system, in particular to a kind of oil-electric hybrid electric vehicle drive system, which can realize multiple drive modes. [0002] technical background [0003] The increasingly serious energy and environmental crisis has brought enormous pressure to traditional vehicles. Therefore, the development of ultra-low-emission or zero-emission electric vehicles has become an important way to solve this problem. There is no doubt that pure electric vehicles are the best way to achieve zero emissions. Countries around the world also regard pure electric vehicles as one of the focuses of research and development, especially electric vehicles driven by in-wheel motors because of their simplified overall vehicle layout and active chassis control. As well as the obvious technical advantages in terms of ease of manipulation, it has attracted widespread attention from industry and academia. However, the development of...
