Description
Technical field
The present invention relates to a kind of electric automobile field, particularly a kind of process for gear of electric automobile.
Background technology
Pure electric automobile directly takes fixed speed ratio mode of the retarder to decelerating through motor, unlike conventional fuel oil automobile is taken
The mode speed change of physics.Driver can reach very high speed per hour for several seconds, and the characteristics of electric automobile be it is very quiet, so
Once for pedestrian and the safety of itself having larger hidden danger.
The content of the invention
The object of the present invention is to provide a kind of gear shift method of electric automobile, can be relatively easy to shift gears.
Technical solution provided by the invention is：
A kind of gear shift method of electric automobile, comprises the following steps：
(1) automatic catch is switched to manual gear：Shift handle is located at the position of the gear of selector 1, switching signal is produced one
High level 1, entire car controller judge whether current vehicle speed is zero, if not zero stops calculating, if zero, then allow the input signal
1 is calculated 1 with default value 0, represents manually, wherein default value 0 represents automatically；
(2) upshift under manual gear pattern and downshift switching：Upshift switches：After being switched under manual mode, it is defaulted as
Manual N gears, entire car controller are opened for what 5 gears of shift handle to selector and 6 gears and automatic N gears and R gears were exported
OFF signal does not perform；When shift handle to one time 2 gear, that is, produce the switching signal of one time 1,1,0,0 and combine, entire car controller carries
For the request of a upshift, the gear of advance 1 is switched to；Velocity interval of this 1 gear is limited in 0 between Vmax1, if control crank
To rise again once keep off to 2 gear, entire car controller will determine that current vehicle velocity V whether ideal gearshift region Vmax1-L~
Vmax1, if less than ideal shift gears region, speed is too low after gearshift, then the moment of torsion exported can with its less than Vmax1-L value into
Inverse correlation calculates, and the moment of torsion exported after V reaches Vmax1-L is just only related to accelerator pedal signal；And so on carry out 2 gear
To the switching of 3 gears；Downshift switches：When manipulation shift handle to 4 is kept off one time, AMT selectors produce one group of switching signal 1,0,
1,0, entire car controller judges that this is downshift request, if gear is 2 gears before downshift, speed is higher than Vmax1, entire car controller control
Vehicle processed temporarily keeps sliding；When bend the throttle, entire car controller request is recovered energy and reduced in a manner of generating electricity
Speed enables accelerator pedal signal to stopping power generation after Vmax1, and speed is limited within Vmax1；And so on carry out it is each
A gear downshift；When downshift is to neutral gear, vehicle control unit controls vehicle sliding, accelerator pedal signal is invalid；
(3) when entire car controller judges currently then to shift to 1,0,0,0 quilt of level obtained when position 3 is kept off as automatic catch
It is judged as that D is kept off, position 5 keeps off obtained level 0,1,0,0 and is judged as N gears, and the level 0,0,1,0 that position 6 obtains is judged as R
It is invalid that the level that gear, 2 gears and 4 gears export under automatic gear pattern is judged as, and is failure to actuate.
The present invention borrows the selector of conventional fuel-engined vehicle to realize manual shift and self shifter, and when manual shift passes through
Gear level is manipulated to 6 functional locations, to export the switching signal of gear to entire car controller, entire car controller is according to this 6
The corresponding switching signal combination of functional location judges gear, and sending variable block then in conjunction with vehicle's current condition confirms instruction, finally
Change the power output codomain of current shift by electric machine controller, and gear is included on combination instrument, realize speed change；
Reach gearshift purpose in cost-effective manner, do not sacrifice transmission efficiency.After having this gearshift mode, first solves mistake
Operate the danger brought；Second can be relatively easy to speed control certain shift control in driver in a certain range
Scope fluctuates substantial amounts of energy content of battery loss that is excessive and bringing so as to reduce anxious acceleration or velocity variations, improves and drives power consumption
Economy.
Embodiment
A kind of gear shift method of electric automobile, comprises the following steps：
(1) automatic catch is switched to manual gear：Shift handle is located at the position of the gear of selector 1, switching signal is produced one
High level 1, entire car controller judge whether current vehicle speed is zero, if not zero stops calculating, if zero, then allow the input signal
1 is calculated 1 with default value 0, represents manually, wherein default value 0 represents automatically；
(2) upshift under manual gear pattern and downshift switching：Upshift switches：After being switched under manual mode, it is defaulted as
Manual N gears, entire car controller are opened for what 5 gears of shift handle to selector and 6 gears and automatic N gears and R gears were exported
OFF signal does not perform；When shift handle to one time 2 gear, that is, produce the switching signal of one time 1,1,0,0 and combine, entire car controller carries
For the request of a upshift, the gear of advance 1 is switched to；Velocity interval of this 1 gear is limited in 0 between Vmax1, if control crank
To rise again once keep off to 2 gear, entire car controller will determine that current vehicle velocity V whether ideal gearshift region Vmax1-L~
Vmax1, if less than ideal shift gears region, speed is too low after gearshift, then the moment of torsion exported can with its less than Vmax1-L value into
Inverse correlation calculates, and the moment of torsion exported after V reaches Vmax1-L is just only related to accelerator pedal signal；And so on carry out 2 gear
To the switching of 3 gears；Downshift switches：When manipulation shift handle to 4 is kept off one time, AMT selectors produce one group of switching signal 1,0,
1,0, entire car controller judges that this is downshift request, if gear is 2 gears before downshift, speed is higher than Vmax1, entire car controller control
Vehicle processed temporarily keeps sliding；When bend the throttle, entire car controller request is recovered energy and reduced in a manner of generating electricity
Speed enables accelerator pedal signal to stopping power generation after Vmax1, and speed is limited within Vmax1；And so on carry out it is each
A gear downshift；When downshift is to neutral gear, vehicle control unit controls vehicle sliding, accelerator pedal signal is invalid；
(3) when entire car controller judges currently then to shift to 1,0,0,0 quilt of level obtained when position 3 is kept off as automatic catch
It is judged as that D is kept off, position 5 keeps off obtained level 0,1,0,0 and is judged as N gears, and the level 0,0,1,0 that position 6 obtains is judged as R
It is invalid that the level that gear, 2 gears and 4 gears export under automatic gear pattern is judged as, and is failure to actuate.
The present invention reaches gearshift purpose in cost-effective manner, does not sacrifice transmission efficiency.There is this gearshift mode
Afterwards, first solves the danger that maloperation is brought；Speed can be compared shift control in a certain range by second in driver
Easy control fluctuates the substantial amounts of energy content of battery that is excessive and bringing in a certain range so as to reduce anxious acceleration or velocity variations
Loss, improves and drives power consumption economy.
