Description
Technical field
The present invention relates to the control method and device that hybrid electric vehicle engine is shut down, belong to Development of HEV Technology
Field.
Background technology
Hybrid vehicle is defined as the vehicle that at least a kind of accumulator, the energy or energy converter provide electric energy,
Hybrid vehicle is in the process of running, it is desirable to engine is operated in higher efficiency area, now engine need often start and
Shut down.
The closing method of following single shaft double-motor hybrid power system engine is commonly used in the prior art：
As shown in Fig. 2 ISG motors apply anti-torque to engine, drag engine relatively low to a certain setting when counter
During rotating speed, generally 300rpm, the anti-torque that revocation ISG motors apply.The shortcomings that the method is that the rotating speed of engine exists
Rotating speed measring during below 300rpm is very inaccurate, otherwise ISG motors is removed anti-torque too early, otherwise remove too late anti-
Torques.ISG motors remove anti-torque and also result in engine too late to be inverted, to avoid engine reversion necessary
Removing ISG motor anti-torques in advance shuts down engine, and removing anti-torque ahead of time will cause vehicle to vibrate abnormal sound,
Especially when engine will stop operating, because rotary inertia is larger, abnormal sound at shaft universal-joint is caused, influences vehicle
Ride comfort.
The content of the invention
It is existing for overcoming it is an object of the invention to provide a kind of hybrid electric vehicle engine halt control method and device
There is the defects of technology, solve the problems, such as the vehicle abnormal sound in engine stopping process.
In order to solve the above technical problems, the present invention proposes a kind of hybrid electric vehicle engine halt control method, including
Following steps：
When engine is shut down, apply ISG motor anti-torques T to engine；Detection ISG motor speeds in real time, work as ISG
When the current rotating speed of motor is less than the ISG motor rotating speed of target for starting to be set when shutting down, the anti-torque of ISG motors is cancelled.
Further, the main drive motor rotating speed size when ISG motors rotating speed of target size=start is shut down is multiplied by
K, k are the no-load voltage ratio of planetary transmission.
In order to solve the above technical problems, the present invention also proposes a kind of hybrid electric vehicle engine stop control apparatus, wrap
Include：
When being shut down for engine, apply ISG motor anti-torques T to engine；Detection ISG motor speeds in real time,
When the current rotating speed of ISG motors is less than the ISG motor rotating speed of target of setting when starting to shut down, the anti-work of ISG motors is cancelled
With the device of torque.
Further, the main drive motor rotating speed size when ISG motors rotating speed of target size=start is shut down is multiplied by
K, k are the no-load voltage ratio of planetary transmission.
The beneficial effects of the invention are as follows：Hybrid electric vehicle engine halt control method proposed by the present invention and device,
Due to ISG motors rotating speed of target and shutdown when vehicle speed positive correlation, therefore engine intelligent shut down during adopt
It is less than the mode of ISG motor rotating speed of target when starting to shut down with control ISG motor speeds, shuts down control as engine and complete
Judgement mark, realize engine shut down closed-loop control, it is whole caused by so as to avoid removing ISG motor anti-torques too early
Car abnormal sound problem.
Brief description of the drawings
Fig. 1 is the structural representation of double-motor hybrid drive system；
Fig. 2 is currently used hybrid electric vehicle engine halt control method flow chart；
Fig. 3 is the control method flow chart that the hybrid electric vehicle engine of the present invention is shut down.
Embodiment
The embodiment of the present invention is further described below in conjunction with the accompanying drawings.
The embodiment of the hybrid electric vehicle engine halt control method of the present invention：
As shown in figure 1, the hybrid vehicle application of the present invention is that a kind of double-motor hybrid with gearbox drives
Dynamic system, including engine 1, ISG motors 13, main drive motor 7 and the planet tooth being connected between generator and motor
Mechanism is taken turns, as shown in Figure 1.The planetary gears mainly includes two sun gears, two output shafts, planet carrier 5.Described hair
Motivation 1 is connected by torsion vibration absorber 2 with drive end gear 3, and drive end gear 3 is connected by driven end gear 4 and planet carrier 5
Connect, so as to output power on planetary gears；Sun gear 6 is connected by output shaft 9 with main drive motor 7, sun gear
12 are connected by output shaft 14 with ISG motors 13, and the power on planetary gears passes through sun gear 6, output shaft 9 and too respectively
Sun wheel 12, output shaft 14 are exported to both ends；Main drive motor 7 is connected drive by traditional axle with the main reducing gear of back axle 8
Dynamic vehicle；Electrical source of power 11 is connected by AC/DC convertor 10 with ISG motors 13 and main drive motor 7.
The control shut down based on above-mentioned double-motor hybrid drive system, hybrid electric vehicle engine of the invention
Method applies ISG motor anti-torque T to engine, detects ISG motors in real time and turn as shown in figure 3, when engine is shut down
Speed, when the current rotating speed of ISG motors is less than the ISG motor rotating speed of target ISG_Spd of setting when starting to shut down, cancel ISG
The anti-torque of motor, complete engine and shut down control.
Above-mentioned ISG motors rotating speed of target ISG_Spd determination is calculated by determining main drive motor rotating speed.Specifically
, ISG motor rotating speed of target ISG_Spd size is directly proportional to main drive motor rotating speed Mot_Spd sizes, ISG motor targets
Rotating speed ISG_Spd direction is in opposite direction with main drive motor rotating speed Mot_Spd's, i.e. ISG_Spd=-k*Mot_Spd, k are
The ratio between the number of teeth of driven end gear 4 and the number of teeth of sun gear 6.
The present invention shuts down as engine and controlled by the way of control ISG motor speeds are less than or equal to rotating speed of target
The judgement mark of completion, realizes that engine shuts down closed-loop control, effectively prevent caused by engine speed detects inaccuracy and sends out
Motivation shuts down the problem of producing vehicle abnormal sound.
The present invention also provides a kind of embodiment for the control device that hybrid electric vehicle engine is shut down：
During including being shut down for engine, apply ISG motor anti-torques T to engine；Detection ISG motors turn in real time
Speed, when the current rotating speed of ISG motors is less than the ISG motor rotating speed of target of setting when starting to shut down, cancel the anti-of ISG motors
The device of torques.
The control device that signified hybrid electric vehicle engine is shut down in above-described embodiment, is actually based on present invention side
A kind of computer solution of method flow, i.e., a kind of software component, said apparatus are the processing corresponding with method flow
Process.The software can be used in entire car controller.Due to the introduction to the above method, sufficiently clear is complete, and this implementation
The device that example is claimed is actually a kind of software architecture, therefore is no longer described in detail.
