To make the above purposes, features and advantages of the invention more obvious and understandable, with reference to the accompanying drawing to the present invention
Specific embodiment explain in detail.
As shown in Fig. 2, the method may include following steps the embodiment provides a kind of control method for vehicle
It is rapid:
Step 21, the current state information of high-tension battery is acquired.
In specific implementation, the current state information of the high-tension battery can be the state-of-charge letter of the high-tension battery
Breath, is also possible to the available power information of the high-tension battery, other that can also be the high-tension battery may determine that charging
The status information whether power is limited.
Step 22, judge whether the charge power of the high-tension battery is limited.
In specific implementation, can according to collected status information be come the charge power for judging the high-tension battery

When collecting the state of charge information of the high-tension battery, the high-tension battery can be judged using various ways
Charge power whether be limited.For example, the collected information of institute can be compared with the first preset threshold.When being collected
Information when being lower than the first preset threshold, determine that the charge power of the high-tension battery is limited.
When collecting the available power information of the high-tension battery, the high-tension battery can be judged using various ways
Charge power whether be limited.For example, the collected information of institute can be compared with the second preset threshold.When being collected
Information when being lower than the second preset threshold, determine that the charge power of the high-tension battery is limited.
It should be noted that first preset threshold and the second preset threshold can be by those skilled in the art according to passing through reality
It the means such as tests to be obtained ahead of time, specific value is unrestricted, as long as according to the numerical value of above-mentioned setting, it can be determined that the high-tension battery
Charge power it is whether limited.
When the charge power of the high-tension battery is by limited time, otherwise execution step 23 terminates entire control flow.
Step 23, it detects whether to receive upshift request.
In specific implementation, what the operation that the upshift request can be driver generated, it is also possible to vehicle control device
It is generated according to vehicle's current condition.For example, in the vehicle with automatic transmission, when the current speed of the vehicle or
When the revolving speed of power source reaches preset value, vehicle control device automatically generates the upshift request.
In specific implementation, the vehicle, which is upshiftd in high-tension battery charge power by generation in limited time, requests corresponding vehicle
The revolving speed of speed and power source, the respectively lower than described vehicle are not requested institute by same upshift is generated in limited time in high-tension battery charge power

Upshift control is carried out to the vehicle, high-tension battery is more advantageous to and absorbs the electric energy that first motor generates, so that described the
The revolving speed of one motor can smoothly decline.
When receiving upshift request, step 24 is executed, it is no to then follow the steps 25.
Step 24, the engine stop oil spout is controlled, and is engine power supply, and control by second motor
The first motor reduction of speed is made to preset rotation speed, drives the vehicle to upshift by the first motor.

The electric energy that first motor generates can be preferably absorbed, and the non-concurrent electric energy for absorbing first motor and the generation of the second motor.By
This first motor can export biggish negative torque, so that the revolving speed of the first motor can be with rapid decrease, and drive vehicle
Upshift avoids the case where can not declining the failure of appearance upshift or upshift time course because of revolving speed in shifting up operation.
In one embodiment of this invention, when the vehicle drives the vehicle liter by first motor and the second motor jointly
When shelves, after the revolving speed of first motor is down to preset rotation speed, the first motor is controlled with preset rotation speed and drives the vehicle, with
This can be driven by second motor with the first motor jointly at the same time it can also control second motor reduction
Move the vehicle upshift.
It should be noted that revolving speed after the preset rotation speed and the second motor reduction can by those skilled in the art according to
The corresponding power source speed of different stalls or speed are determined.It is understood that drive the power source of the vehicle different,
Revolving speed after the preset rotation speed and the second motor reduction also can be corresponding different.
Step 25, judge whether to receive deceleration request.
In specific implementation, what the operation that the deceleration request can be driver generated, it is also possible to vehicle control device
It is generated according to vehicle's current condition.For example, in the vehicle with automatic transmission, when vehicle control device detects the vehicle
When under the damped condition, corresponding deceleration request can be generated.
When receiving deceleration request, step 26 is executed, entire control flow is otherwise terminated.
Step 26, the engine stop oil spout is controlled, and is engine power supply, and control by second motor
It makes the first motor and drives the vehicle deceleration.
When the vehicle is driven by first motor, if receive deceleration request, on the one hand controls the engine and stop
Only oil spout, and be engine power supply by the second motor, the first motor reduction of speed is on the other hand controlled to preset rotation speed.When
Engine stop oil spout, and the second motor be the engine power when, the engine can still keep rotating, corresponding component
It can still be normally carried out and take a breath and power is generated by friction.The engine is during ventilation by made by pumping loss
Function and when generating power by friction work done, can be absorbed the second motor generation electric energy, i.e., the second motor is counter drags
Engine power consumption so that high-tension battery can preferably absorb first motor generation electric energy, and it is non-concurrent absorb first
The electric energy that motor and the second motor generate.Thus first motor can export biggish negative torque, thus the first motor
Revolving speed can be with rapid decrease, and drives vehicle deceleration, avoids occurring the case where vehicle shake in moderating process.
When the vehicle is driven by first motor and the second motor collectively as power source, in the first motor
After reduction of speed to preset rotation speed, second motor reduction can also be controlled, and then can be by second motor and described first
Motor drives the vehicle deceleration jointly.
It should be noted that although the above embodiment of the present invention is said by taking the dynamical system of hybrid vehicle as an example
It is bright, but it is understood that, the control control method for vehicle is not limited to apply in hybrid vehicle, can also answer
In other automobiles, as long as the vehicle includes first motor and the second motor connecting with engine, the present invention
This is not specifically limited.
As shown in the above, control method for vehicle in the embodiment of the present invention can rise accurately determining that vehicle is in
The charge power of shelves state and high-tension battery is powered by limited time by controlling the engine that the second motor is stopping oil spout,
And then high-tension battery can preferably absorb the electric energy of first motor generation, therefore the revolving speed of the first motor can be made suitable
Benefit decline prevents vehicle from will appear upshift overlong time during upshift or the case where the failing that upshift, improves vehicle
Upshift performance.
