Description
Technical field
The present invention relates to a kind of control method of automatic transmission, the more precisely a kind of gear of electric automobile two line traffic control is certainly
Dynamic variator upshift intervenes control method.
Background technology
Automatic transmission is widely used in the various vehicles such as automobile, electric automobile, engineering machinery.Existing automatic transmission
Mainly there are hydraulic mechanical type automatic transmission (AT), metal band type ST (CVT), automatic mechanical transmission
(AMT), double-clutch automatic transmission (DCT) four major types.
Above-mentioned four classes automatic transmission adopts electric-controlled hydraulic servomechanism installation, realizes shift process control, complex structure, into
This height and increased control difficulty and complexity.The especially actuator of DCT includes：By hydraulic pump, hydraulic valve and accumulator
The oil supply mechanism of composition, by hydraulic pressure or motor-driven pulsewidth modulation gear shifting actuating mechanism, by hydraulic pressure or motor-driven clutch
Device operating mechanism.These hydraulic controls cause variator complicated integral structure, high cost and increased control difficulty and answer
Miscellaneous degree.
With automotive electronic technology, the extensive application of the progressively ripe and automobile network communication technology of automatic control technology,
X-by-wire on Automobile has become following development trend of automobile.Automobile line traffic control (X-By-Wire) technology is exactly with electric wire and electronics
The control action of driver is become the signal of telecommunication through sensor, is input to automatically controlled replacing mechanically and hydraulically system by controller
Unit, produces control signal by ECU and drives actuator to carry out action required.X-by-wire on Automobile can reduce part
Complexity, reduce hydraulic pressure and mechanical driving device, while electric wire move towards the freedom that the motility of arrangement expands Automobile Design
Space.
To realize that driver need not interrupt motor and line traffic control in the power shifting of line traffic control automatic transmission, i.e. shift process
Power between automatic transmission, if not to motor using intervention control, in shift process, motor speed can not meet and change
The requirement of gear rotating speed, so as to cause shift shock, and reduces the life-span of motor and line traffic control automatic transmission.To guarantee electronic vapour
Car two keeps off the steady gearshift of line traffic control automatic transmission, it is to avoid the interruption of motor input power and shift shock in shift process,
The shift process that electric automobile two keeps off line traffic control automatic transmission must be controlled.
The content of the invention
It is an object of the invention to provide a kind of interruption and gearshift that can either avoid motor input power in shift process
Impact, can realize two gear line traffic control automatic transmission upshift intervention control methods of the steady upshift of electric automobile again.It is a kind of electronic
The gear line traffic control automatic transmission upshift intervention control method of automobile two, realizes that the gear line traffic control of electric automobile two of the control method becomes automatically
The control system of fast device includes that variator ECU, motor ECU, motor, D position switch, transmission output shaft turn
Fast sensor, motor speed sensor, accelerator pedal position sensor, a gear electromagnetic clutch, two gear electromagnetic clutchs,
A gear is previously stored in variator ECU and has risen two gear law curves.
Technical scheme is as follows：
After motor starting, electricity on variator ECU and motor ECU, the gear line traffic control fluid drive of electric automobile two
Device upshift intervention control method brings into operation, and the control method is comprised the following steps：
Step 1, variator ECU detection D stop the tach signal n of OFF signal, transmission output speed sensor2, electricity
The tach signal n of motivation speed probe1, accelerator pedal position sensor opening amount signal α；
Step 2, judge whether to be linked into D gears：When variator ECU detects D stops OFF signal connection, it is judged as being linked into D
Gear, carries out step 3；Otherwise, when variator ECU detects D stops OFF signal access failure, judge not to be linked into D gears,
Return to step 1；
Step 3, judge whether need by one gear rise two gears：When variator ECU detects transmission output speed sensing
The tach signal n of device2The gear line traffic control of electric automobile two automatic transmission one is met with the opening amount signal α of accelerator pedal position sensor
When gear rises the liter catch point that two keep off on law curve, be judged as needing two gears to be risen by a gear, carry out step 4；Otherwise, when variator electricity
Control unit detects the tach signal n of transmission output speed sensor2With the opening amount signal α of accelerator pedal position sensor
It is unsatisfactory for the gear of electric automobile two line traffic control automatic transmission one to keep off when rising liter catch point that two keep off on law curves, being judged as need not be by
One gear rises two and keeps off, and returns to step 1；
Step 4, a gear rise two and keep off process control：Variator ECU passes through the transmission output speed sensor for detecting
Tach signal n2Two are risen with a gear and keeps off motor rotating speed of target function f (n2)=βn2[(Z1Z11)/(Z0Z10)- (Z2Z21)/
(Z0Z20)]/ [(Z1Z11)/(Z0Z10)] determine that a gear rises two and keeps off motor rotating speed of target, motor ECU control motor
Rotating speed reaches a gear and rises two gear motor rotating speed of target, in formula：n2For the rotating speed of transmission output shaft；Z0For the tooth of input gear
Number；Z1For the number of teeth of a gear input gear； Z10For the number of teeth of a gear driving gear；Z11For the number of teeth of a gear driven gear；Z2For
The number of teeth of two gear input gears；Z20For the number of teeth of two gear driving gear；Z21For the number of teeth of two gear driven gears；β is upshift target
Rotation speed change coefficient；
Step 5, judge one gear rise two gear whether terminate：Control process motor speed n is kept off when a gear rises two1More than or equal to a gear
Rise two and keep off motor rotating speed of target f (n2) when, it is judged as that a gear rises two gear control process and not yet terminates, returns to step 4；It is no
Then, control process motor speed n is kept off when a gear rises two1Two are risen less than a gear and keeps off motor rotating speed of target f (n2) when, it is judged as
One gear rises two gear control process to be terminated, and returns to step 1；
After driver's shut-off ignition switch, variator ECU and motor ECU power-off, the gear line traffic control of electric automobile two
Automatic transmission upshift intervention control method terminates operation.
Two are risen in the gear of above-mentioned steps 4 one and keeps off process control, upshift target revolution speed variation factor beta is a fixation of setting
Value, β=0.95～1.05.
Compared with prior art, its advantage is the present invention：
The gear line traffic control automatic transmission upshift intervention control method of electric automobile two of the present invention, is controlled by the way of upshift intervention
Motor speed, rises two gear motor rotating speed of target functions according to a gear and determines motor upshift rotating speed of target, by variator electricity
Control signal is conveyed to motor ECU by control unit, and motor ECU controls motor speed, in driver just
Realize smooth-going upshift, it is to avoid the shift shock and power interruption during upshift accelerator pedal is manipulated often in the case of.
