Clutch 23 is in non-lockup state, and 9 and 10 in the first engaging element are closed, and engine 1 and wheel are full decoupled.
First parallel mixed dynamic dynamic mode：By engine 1 and the second energy supply jointly of motor 3.One-way clutch 23 at this time
10 and 11 in non-lockup state, the first engaging element and second 14 and 15 being closed in engaging element, first motor
2 are locked up, and the second motor 3 carries out active adjusting to engine working point.
Second parallel mixed dynamic dynamic mode：By engine 1, first motor 2 and the second energy supply jointly of motor 3.It is single at this time
It is in non-lockup state to clutch 23,9 and 10 in the first engaging element and second 14 and 15 being closed in engaging element,
First motor 2 and the second motor 3 carry out active adjusting to engine working point.
For starting and low speed operational process：
Higher in Vehicular battery SOC, when vehicle remains static, it is pure that single motor may be used in vehicle at this time
Electronic subpattern carries out pure electric vehicle starting, and vehicle pure motor driving is operated alone to certain speed by the second motor 3；Work as vehicle
When power demand is larger, when the subpattern of single motor pure electric vehicle cannot provide required power, or when using single motor pure electric vehicle
When modular system is relatively inefficient, bi-motor pure electric vehicle subpattern starting may be used, and travel to certain speed, herein
For one-way clutch by 11 locking of engine 1 and case of transmission, engine 1 will not be dragged in the process.Certainly, if removed single
To clutch 23, then reduce by an engaging element, but only exist single motor pure electric vehicle subpattern at this time, or in the pure electricity of bi-motor
Engine 1 will be in dragging state in mover pattern.
Lower in Vehicular battery SOC, when vehicle remains static, vehicle can pass through two ways at this time
It starts to walk and is exercised to certain speed in certain vehicle speed range：First, input power shunting hybrid mode starts to walk
And it travels to certain speed.In this mode, one-way clutch 23 is in lockup state, the output power of engine do not pass through
Single planetary row is shunted, and first motor 2 and the second motor 3 are respectively as generator or motor to 1 operating point of engine
It is adjusted, while ensureing higher starting dynamic property, improves the fuel consumption rate of engine；Second, tandem mixing is dynamic
Force mode is started to walk and is travelled to certain speed.In this mode, engine and wheel are full decoupled, and engine is operated in
Optimal working point drives vehicle start by the second motor 3.
For middle speed hybrid operational process：
When vehicle is started to walk by electric-only mode and is travelled after a certain period of time, when battery SOC is higher, vehicle can pass through list
Motor pure motor driving is then switched to bi-motor pure electric vehicle drive mode to certain speed, ensures vehicle in full speed range
Pure motor driving.When SOC value of battery drops to certain level or system effectiveness is relatively low, vehicle can be pure by single motor
Electronic subpattern or bi-motor pure electric vehicle subpattern switch to input power shunting hybrid mode.
For mixed at high speed power operational process：
When vehicle is started to walk by electric-only mode and is travelled after a certain period of time, when battery SOC is higher, vehicle can be by double
Motor pure electric vehicle drive mode.When SOC value of battery drops to certain level or system effectiveness is relatively low, vehicle can be by
Input power shunting hybrid mode switches to parallel type hybrid dynamic pattern, when avoiding high speed, input power shunt mode
The problem of causing efficiency to reduce due to power cycle.
For mode handover procedure：
The mixed dynamic dynamic mode of tandem is switched to for single motor electric-only mode：Due to the not passing power of first gear 8,
Directly close 9 and 10 in the first shifting element.
The mixed dynamic dynamic mode of input power shunting is switched to for the mixed dynamic dynamic mode of tandem：It needs to open the first shift
14 and 15 in the second shifting element are closed in 9 in element and 10.In the process, it is changed first first with first motor 2
9 and 10 unloadings in element are kept off, then it is opened, the second motor 3 is then utilized to ensure the power of output end, utilize the first electricity
14 and 15 speed discrepancies in 2 the second shifting element of active accommodation of machine are then shut off to certain level, complete the switching of pattern.
Or do not open first in the first shifting element 9 and 10, close 14 in the second shifting element and 15 first, then
9 and 10 in opening the first shifting element.
Input power, which is switched to, for single motor pure electric vehicle subpattern shunts hybrid mode：First, second is closed to change
14 and 15 in shelves element, since third gear 16 dallies, torque is not transmitted, the first engaging element can be directly closed.So
Afterwards, engine is started using first motor 2.After utilizing first motor 2 to pull engine 1 to certain rotating speed at this time,
Engine 1 carries out oil spout igniting and starts.Torque to reduce the outburst of engine start moment influences vehicle comfort, needs at this time
It wants first motor to carry out of short duration power generation to be balanced the outburst torque of engine start moment, then vehicle enters input power
Shunt hybrid mode.
Or it is closed 9 in the first engaging element and 10 first, entire planetary gear rotates at the same speed at this time, utilizes the first electricity
After machine 2 pulls engine 1 to certain rotating speed, engine 1 carries out oil spout igniting and starts.Then it detaches in the first engaging element
9 and 10.But since the first engaging element is that synchronizer or dog tooth clutch at this time can not in the case of passing power
It is directly separated by the executing agency of engaging element, so to be carried out to 9 and 10 in the first engaging element using first motor 2
Unloading, then again detaches it.
Parallel mixed dynamic dynamic mode is switched to for input power shunting hybrid mode：Input power shunting mixing
Dynamic mode is compared with parallel mixed dynamic dynamic mode, and a mechanical constraint is lacked on mechanical connection, is thus caused the 4th
It, can be by first motor 2 to engine speed or the gear shift that will be engaged in the case that 22 rotating speed of transmission shaft remains unchanged
Element principal and subordinate end speed discrepancy carries out active adjusting, while ensureing vehicle power output, will will fast and effeciently can connect
The engaging element principal and subordinate end speed discrepancy of conjunction is contracted to certain level, is then engaged by engaging element executing agency corresponding synchronous
Device or dog tooth clutch.
