Change speed gear box parked state releases.
After using technique scheme, after driver presses P gear switch, TCU receives switching signal, and TCU judges that vehicle is in
During dead ship condition, the independent at least two automatic gearshift that controls enters shelves simultaneously, and the automatic gearshift being now controlled divides
Not being linked into each self-corresponding gear, now at least two shelves hung by change speed gear box simultaneously, owing to the speed ratio of each grade is different, cause becoming
The rotary freedom of speed case input and output shaft is 0, and change speed gear box is in the lock state, and output shaft of gear-box can not rotate, therefore car
Wheel also cannot rotate, and vehicle is in parked state, and it is on the basis of original parking brake, increases the function of change speed gear box parking, does not increases
Adding system cost, and improve ramp parking stability.
Accompanying drawing explanation
Fig. 1 is the schematic block diagram of the present invention.
Detailed description of the invention
A kind of method that pure electric automobile realizes parking by AMT change speed gear box, is shown in Fig. 1: its arrange on AMT change speed gear box to
Few two independent automatic gearshifts, each automatic gearshift independently controls the gear of correspondence, and driver presses P gear switch
After, TCU receives switching signal, and TCU judges when vehicle is in dead ship condition, and independent control at least two automatic gearshift is simultaneously
Entering shelves, the automatic gearshift being now controlled is linked into each self-corresponding gear respectively, and now change speed gear box hangs at least two simultaneously
Individual shelves, owing to the speed ratio of each grade is different, the rotary freedom causing change speed gear box input and output shaft is 0, and change speed gear box is in lock
Determining state, output shaft of gear-box can not rotate, and therefore wheel also cannot rotate, and vehicle is in parked state, and driver releases P shelves and opens
After pass, corresponding automatic gearshift simultaneously returns to neutral, and output shaft of gear-box recovers rotary freedom, change speed gear box parking shape
State releases, and reverts to normal operating conditions.
Specific embodiment: AMT change speed gear box is specially the AMT change speed gear box of at least four shelves, it includes at least two independence
Automatic gearshift, each automatic gearshift controls two gears respectively, and wherein the first automatic gearshift controls 1/2 grade,
Second self shifter structure control 3/4 grade, after driver presses P gear switch, TCU receives switching signal, and TCU judges that vehicle is in and stops
During car state, control the first automatic gearshift respectively and change speed gear box is linked into 1 grade or 2 grades, second self shifter structure general's change
Speed case is linked into 3 grades or 4 grades, and the first automatic gearshift, the second self shifter structure are linked into different gear simultaneously, due to two
The speed ratio of shelves is different, and the rotary freedom causing change speed gear box input and output shaft is 0, and change speed gear box is in the lock state, at vehicle
In parked state;After driver releases P gear switch, two gearshifts simultaneously return to neutral, and output shaft of gear-box recovers to rotate
Degree of freedom, change speed gear box parked state releases;
When AMT change speed gear box includes three gears, the first automatic gearshift controls 1/2 grade, the second self shifter structure
Controlling 3 grades, after driver presses P gear switch, TCU receives switching signal, and TCU judges, when vehicle is in dead ship condition, to control respectively
First automatic gearshift change speed gear box is linked into 1 grade or 2 grades, the second self shifter structure change speed gear box is linked into 3 grades, first from
Move retaining device, the second self shifter structure is linked into different gear simultaneously, owing to the speed ratio of two shelves is different, causes change speed gear box
