Description

Electric automobile three gear line traffic control automatic transmission upshift intervention control method
Technical field
The present invention relates to a kind of control method of automatic transmission, more precisely a kind of electric automobile three gear line traffic control is certainly Dynamic variator upshift intervenes control method.
Background technology
Automatic transmission is widely used in the various vehicle 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 class automatic transmission, all using electric-controlled hydraulic servomechanism installation, realize shift process control, complex structure, one-tenth 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 make variator complicated integral structure, high cost and increased control difficulty and answer Miscellaneous degree.
With the extensive application of automotive electronic technology, 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 Controller, to replace mechanically and hydraulically system, the control action of driver is become the signal of telecommunication through sensor, is input to automatically controlled 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, electric wire move towards the motility of arrangement and expands the freedom of Automobile Design simultaneously Space.
For realizing the power shifting of line traffic control automatic transmission, that is, in shift process, driver need not interrupt motor and line traffic control Power between automatic transmission, if not controlled using intervention to motor, in shift process, motor speed can not meet and change The requirement of gear rotating speed, thus causing shift shock, and reduces motor and the life-span of line traffic control automatic transmission.For guaranteeing electronic vapour Car three 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 line traffic control automatic transmission must be kept off to electric automobile three is controlled.
Content of the invention
It is an object of the invention to provide a kind of can either avoid the interruption of motor input power and gearshift in shift process Impact, is capable of three gear line traffic control automatic transmission upshift intervention control methods of the steady upshift of electric automobile again.A kind of electronic Automobile three gear line traffic control automatic transmission upshift intervention control method, the electric automobile three gear line traffic control realizing this control method becomes automatically The control system of fast device includes variator ECU, motor ECU, motor, d position switch, transmission output shaft turn Fast sensor, motor speed sensor, accelerator pedal position sensor, one gear electromagnetic clutch, two gear electromagnetic clutchs, three Gear electromagnetic clutch, has been previously stored a gear liter two gear law curves, two gears rise three gear rules songs in variator ECU Line.
Technical scheme is as follows:
After motor starting, electricity on variator ECU and motor ECU, electric automobile three keeps off line traffic control fluid drive Device upshift intervention control method brings into operation, and this control method comprises the following steps:

Step 4, a gear rise two gear process control: variator ECU (100) passes through the transmission output speed detecting The tach signal n of sensor (oss)2Rise two gear motor rotating speed of target function f with a gear12(n2)=βn2[(z1z11)/(z0z10)- (z2z21)/(z0z20)]/ [(z1z11)/(z0z10)] determine that a gear rises two gear motor rotating speed of target, motor ECU (200) control motor speed to reach a gear and rise two gear motor rotating speed of target, in formula: n2Turning for transmission output shaft (8) Speed;z0The number of teeth for input gear (30);z1The number of teeth for gear input gear (31); z10For gear driving gear (51) The number of teeth;z11The number of teeth for gear driven gear (71);z2The number of teeth for two gears input gear (32);z20For two gear driving gear (52) the number of teeth;z21The number of teeth for two gears driven gear (72);β is upshift target revolution speed variation coefficient;
Step 5, judge one gear rise two gear whether terminate: when one gear rise two gear control process motor speed n1More than or equal to a gear Rise two gear motor rotating speed of target f12(n2) when, it is judged as that a gear rises two gear control process and not yet terminates, return to step 4;No Then, when a gear rises two gear control process motor speed n1Rise two gear motor rotating speed of target f less than a gear12(n2) when, judge Rise two gear control process for a gear to terminate, return to step 1;
Step 6, judge whether need by two gear rise three gears: turn when variator ECU (100) detects transmission output shaft The tach signal n of fast sensor (oss)2Meet electric automobile three gear with the opening amount signal α of accelerator pedal position sensor (aps) In line traffic control automatic transmission upshift law curve, two gears rise three gear law curve (d23) on liter catch point when, be judged as needing by two Gear rises three gears, carries out step 7;Otherwise, when variator ECU (100) detects transmission output speed sensor (oss) tach signal n2It is unsatisfactory for electric automobile three gear line traffic control with the opening amount signal α of accelerator pedal position sensor (aps) certainly In dynamic variator upshift law curve, two gears rise three gear law curve (d23) on liter catch point when, be judged as not needing by two gear rise Three gears, return to step 1;
Step 7, two gears rise three gear process control: variator ECU (100) passes through the transmission output speed detecting The tach signal n of sensor (oss)2Rise three gear motor rotating speed of target function f with two gears23(n2)= βn2[ (z2z21)/ (z0z20)-1]/ [(z2z21)/(z0z20)] determining that two gears rise three gear motor rotating speed of target, motor ECU (200) is controlled Motor speed processed reaches two gears and rises three gear motor rotating speed of target, in formula: n2For transmission output shaft (8) rotating speed;z0For input The number of teeth of gear (30); z2The number of teeth for two gears input gear (32);z20The number of teeth for two gear driving gear (52);z21For two The number of teeth of gear driven gear (72);β is upshift target revolution speed variation coefficient;
Step 8, judge two gear rise three gear whether terminate: when two gear rise three gear control process motor speed n1More than or equal to two gears Rise three gear motor rotating speed of target f23(n2) when, it is judged as that two gears rise three gear control process and not yet terminate, return to step 7;No Then, when two gears rise three gear control process motor speed n1Rise three gear motor rotating speed of target f less than two gears23(n2) when, judge Rise three gear control process for two gears to terminate, return to step 1.
2. electric automobile three as claimed in claim 1 gear line traffic control automatic transmission upshift intervention control method it is characterised in that Rise in three gear process control in described step 4 one gear liter two gear process control, step 7 two gear, described upshift target revolution speed variation Factor beta is the fixed value setting, β=0.95~1.05.
