Specific embodiment
Embodiment 1
As shown in Figures 2 and 3, the present embodiment provides a kind of control method of hybrid vehicle, including
Following steps:
S11：Present mode is obtained, when present mode is series model, execution step S12 to S16,
When present mode is paralleling model, execution step S22 to S26.For example, full-vehicle control can be passed through
Device (HCU) control model sensor obtains present mode.
S12：Judge whether current motor rotating speed meets from series model the mould for being switched to paralleling model
Formula switching condition, if then execution step S13, if otherwise not carrying out any operation.For example, Ke Yitong
Cross HCU and judge that the rotating speed of motor reaches first threshold, if reaching, meet from series model and switch
To the mode changeover condition of paralleling model.Before the T1 moment as shown in Figure 3, car load is in series model,
The rotating speed of motor is stepped up, but without arrival first threshold.
S13：Speed governing is carried out to starting-generating all-in-one so that the rotating speed and driving electricity of starting-generating all-in-one
The speed discrepancy of machine is less than preset value.For example, can judge that the rotating speed of motor reaches first in HCU
During threshold value, controlling starting-generating all-in-one carries out speed governing and judges the rotating speed of starting-generating all-in-one and drive
Whether the speed discrepancy of motor is less than preset value.As shown in figure 3, in T1 moment, the rotating speed of motor
First threshold is reached, HCU sends pattern switching instruction, pattern switching flag bit set, starting-generating one
Body machine starts speed governing；Process of the T1-T2 moment for starting-generating all-in-one speed governing；At the T2 moment, rise
The speed discrepancy of the rotating speed and motor of dynamic power generation all-in-one machine is less than certain value, and HCU sends clutch mode
Action command, regime clutch instruction flag position position.
S14：Control clutch is combined.At the T2 moment, gearbox control (TCU) receives HCU
The clutch mode action command for sending, combines according to the instruction control clutch.
S15：During clutch is combined, whether real-time judge speed meets gearshift condition, if
Then execution step S16, if otherwise not carrying out any operation；
S16：Control starting-generating all-in-one and clutch carry out action to complete pattern switching and gearshift.
S22：Judge whether current motor rotating speed meets from paralleling model the mould for being switched to series model
Formula switching condition, if then execution step S23, if otherwise not carrying out any operation..For example：Can be with
Judge by HCU whether the rotating speed of motor drops to Second Threshold, if so, then meet from simultaneously gang mould
Formula is switched to the mode changeover condition of series model.At the T7-T8 moment as shown in Figure 3, car load is in simultaneously
Gang mould formula, the rotating speed of motor progressively decline, but without dropping to Second Threshold.
S23：Starting-generating all-in-one is unloaded.At the T8 moment, the rotating speed of motor drops to
Second Threshold, HCU send pattern switching instruction, pattern switching flag bit set, starting-generating all-in-one
Start unloading；
S24：After the completion of the unloading of starting-generating all-in-one, clutch separation is controlled.At the T9 moment, start
Power generation all-in-one machine unloading is completed, and HCU is sent to TCU clutch mode separation commands, TCU control clutches
Device is separated.
S25：After the completion of clutch separation, whether real-time judge speed meets gearshift condition, if then
Execution step S26, if it is not, then not carrying out any operation.
S26：Complete pattern switching and gearshift.At the T10 moment, current vehicle speed meets gearshift condition, TCU
Shifting commands are sent, flag bit set of shifting gears starts shift process.In T11 moment (T11 side in figure
The right-hand member of frame), after the completion of clutch separation, car load virtual condition enters series model, and clutch keeps
Released state, each power source torque start to resume work；At the T12 moment, each power source completes moment of torsion
Recover, shift process terminates, so far car load is terminated with shift process by series model switching is parallel to.
By above-mentioned steps S12 to S16, during clutch is combined, go in real time to judge that speed is
It is no to meet gearshift condition, if then starting simultaneously at shift process.This just causes to be switched to simultaneously in series model
During gang mould formula, can be shifted gears simultaneously, the car load pattern switching that greatly shortens and shift process when
Between, car load energy consumption has been saved, car load driving has been optimized；
By above-mentioned steps S22 to S26, after the completion of clutch separation, go in real time whether to judge speed
Meet gearshift condition, if then starting shift process.This just causes to be switched to series model in paralleling model
When, can be shifted gears simultaneously, and clutch is only needed to separate once during being somebody's turn to do, greatly
The car load pattern switching of shortening and the time of shift process, it is to avoid clutch being repeatedly opened and combining,
Car load energy consumption has been saved, car load driving has been optimized.
As a kind of preferred version, as shown in figure 4, above-mentioned steps S26 can include：
S261, unloads to starting-generating all-in-one.At the T3 moment, current vehicle speed meets gearshift bar
Part, TCU send shifting commands, and flag bit set of shifting gears, starting-generating all-in-one start unloading.
S262, after the completion of the unloading of starting-generating all-in-one so that clutch separation.At the T4 moment,
The unloading of starting-generating all-in-one is completed, and TCU sends clutch gear-shift action command, shift clutch instruction
Flag bit set, clutch are initially separated.
S263, after the completion of clutch separation, is shifted gears；Shift process is included to input shaft and output shaft
Speed governing is carried out, makes after input shaft is identical with the speed of output shaft to move lock unit.At the T5 moment,
Clutch separation is completed, and starts shift process.
S264, after the completion of gearshift so that clutch is combined, to complete pattern switching.At the T6 moment,
After the completion of clutch is combined, car load virtual condition enters paralleling model, and clutch keeps bonding state, respectively
Power source torque starts to resume work；At the T7 moment, each power source completes the recovery of moment of torsion, shifted gears
Journey terminates, and so far car load is terminated with car load shift process by paralleling model switching is connected in series to.
By above-mentioned steps S261 to S264 so that clutch is only needed to reference to twice, is separated once,
Just complete car load to be switched to paralleling model by series model and complete gearshift, it is to avoid clutch it is anti-
Strike-on is opened and is combined, and has saved car load energy consumption, optimizes car load driving.
