Signal lights gear indicator light 225.
Entire car controller 21 integrates the signals such as driver's operation, speed, brake signal, motor direction of rotation and judges whether to ring
Using the gear shift operation demand at family, actual gear signal is provided, actual gear signal is sent to selector 22 by CAN message
With display instrument 23.Entire car controller 21 can also carry out gear fault verification, and send out malfunction by CAN bus.
Display instrument 23 shows five gears of P, R, N, D, S, is shown according to actual gear signal to carry out gear.Work as vehicle
When judging gear failure, reminded by display instrument 23 to show that gear failure gives driver.The specific of wherein each gear contains
Justice is：
P：(stopping) car bumper is moored, vehicle needs to hang over this gear after stopping can just pull key；R：Reverse gear shift；N：Neutral gear；D：Before
Into gear, when normal driving, hangs over this gear；S：Motor pattern.
The shift request implementation process corresponding to shifting control system is described in detail below.
When driver operates selector, shifting control system understands driver's gear demand by identification gear information,
And show gear information to prompt driver by display instrument and gear indicator light.When judging gear failure, by aobvious
Show that instrument shows that gear failure gives driver's prompting.Wherein selector is responsible for gear request identification, and entire car controller is responsible for reality
Border shift control.
Wherein, the S gear buttons of selector keep off switching control for D gears and S, and D gears represent Economy urge factor gear, and S gears represent
Movement driving gear；P gears represent parking gear.There are five positions for knob selector, are divided into origin position, knob is to the left, to the right
Respectively there are two sections of strokes, to the left or to the right after rotation, unclamps knob, knob rotates back to origin position automatically.Selector is according to current
Gear, knob selector mode of operation, forward gear memory state, P gear buttons and S gear key-press status comprehensive descisions show that gear is asked
It asks, and entire car controller is sent to by CAN bus.The gear request decision logic of wherein selector is as shown in table 1：
Table 1
In vehicle initial power-on, gear request is defaulted as vacancy.Gear request control method when initial power-on, can be with
The unexpected shift for avoiding occurring driver, ensure that the driving safety of driver.User rotates knob selector to left side
R gears are switched to, are to be consistent with existing rotation shift control, ensure the operating habit of user.
When current shift is that P/N/D/S is kept off, selector detects that user turns left knob selector rotation direction to the second stroke
When, no matter whether S gear buttons are pressed, whether P gear buttons are pressed, forward gear memory state is D gears or S gears, and gear request is R
Gear.
Since forward gear is divided into D gears and S two gears of gear, user can carry out according to drive demand between two gears
Switching, so needing to remember the forward gear state that user selects.When ensureing that user switches to forward gear, gear request choosing
It is selected as forward gear memory state, user does not have to keep off button to select the forward gear of oneself to operate S again, reduces user not
Necessity operation.It is arranged " forward gear memory state ", when initial power-on, " forward gear memory state " is D gears；After the completion of initialization,
If actual gear switches to S gears, " forward gear memory state " keeps off for S；If actual gear switches to D gears, " forward gear is remembered
State " is kept off for D.When in other actual gears, user's operation S keeps off button, is considered as invalid operation, " forward gear memory state "
Initial value is kept, does not switch forward gear memory state.
When current shift is that P/R/N is kept off, when selector detects that user turns right knob selector rotation direction to the second stroke,
No matter whether S gear buttons are pressed, whether P gear buttons are pressed, if forward gear memory state is kept off for D, gear request is that D is kept off.
When current shift is that P/R/N is kept off, when selector detects that user turns right knob selector rotation direction to the second stroke,
No matter whether S gear buttons are pressed, whether P gear buttons are pressed, if forward gear memory state is kept off for S, gear request is that S is kept off.
User, which rotates knob selector to right side, switches to forward gear, is to keep one to shift gears to control with existing rotation
It causes, ensures the operating habit of user.The forward gear state of user's selection is remembered, the driving habit of user can be remembered.
User does not have to keep off button to select the forward gear of oneself to operate S again, reduces the unnecessary operation of user, improves driving
Experience.
When current shift is that D is kept off, selector detects knob selector in origin position, and user presses S gear buttons
When lower, gear request is that S is kept off；When current shift is that S is kept off, selector detects knob selector in origin position, and user
When by S gears by key pressing, gear request is that D is kept off.The switching that D is kept off between S gears keeps off button to realize by S, and knob is not used
Selector carries out shift switching, greatly reduces the complexity of shift control method, and keeping off button by S, to realize that D gears are kept off with S mutual
Mutually switch, meets the demand that user drives gear switching in Economy urge factor gear and movement.
When current shift is that P/R/D/S is kept off, selector detects that user turns left knob selector rotation direction to the first stroke
When, no matter whether S gear buttons are pressed, whether P gear buttons are pressed, forward gear memory state is D gears or S gears, and gear request is N
Gear；When current shift is that P/R/D/S is kept off, when selector detects that user turns right knob selector rotation direction to the first stroke, nothing
Whether pressed by S gear buttons, whether P gear buttons are pressed, forward gear memory state is that D is kept off or S gears, gear request are that N is kept off；I.e.
When current shift is that non-N is kept off, user carries out short stroke gear shift operation, either turns left still toward right rotation short stroke, gear
Request switches to N gears, and short stroke here is the first stroke.
The above control method ensure that left-handed stroke two keeps off for R, and dextrorotation stroke two keeps off for D, and left rotation and right rotation short stroke is N
Gear specifies the corresponding gear request of each rotating distance, greatly reduces the complexity of user's operation.User keeps off from N by knob
Rotation to the second stroke of left side just switches to R gears rather than the first stroke, is that user carries out shift maloperation in order to prevent, rotation
Just allow shift that can more specify the shifting intention of user to the second stroke.
When current shift is that R/N/D/S is kept off, selector detects knob selector in origin position, and user keeps off P
When by key pressing, no matter whether S gear buttons are pressed, forward gear memory state is D gears or S gears, and gear request is that P is kept off.Parking
Gear enters through P gear buttons to realize, rotation shift switching is not used, greatly reduces the complexity of shift control method, full
The foot shift demand of user's parking and traveling.
Knob selector can rotate back to origin position automatically by user's operation stroke, that is, shift gears after user's operation shift
Gear request is instantaneous state.When vehicle operating mode is unsatisfactory for the condition of user's operation shift, entire car controller will not respond use
Family gear request, gear request should switch to former gear.When gear request changes, new gear is asked hair by selector
Timing is proceeded by after going out, if in gear request effective time threshold value, actual gear is switched to gear request unanimously, then
Gear request is kept；If after gear asks effective time threshold value, actual gear asks inconsistent, then gear request with gear
It switches to consistent with actual gear.
The implementation process of the practical shift corresponding to shifting control system is described in detail below.
After selector judges gear request, full-vehicle control carries out actual gear judgement.It is practical to keep off when vehicle initial power-on
Position is defaulted as P gears；Entire car controller comprehensive descision current shift information, electric source modes information, vehicle prepare state, gear is asked
It asks, braking information, speed information and/or motor rotation information, obtains current actual gear.It is practical when selector fault-free to keep off
Position decision logic is as shown in table 2.
Table 2
Under vehicle power-down state (when i.e. electric source modes are OFF), when user powers on, vehicle ignition switch electricity is inhaled
It closes, vehicle low pressure powers on, and electric source modes become ON states from OFF at this time；If user steps on simultaneously under the electric source modes such as OFF/ON
Brake pedal is powered on, vehicle can the above high-voltage electricity, into wheeled pattern, i.e. vehicle enters preparation state.
When vehicle initial power-on, i.e., when electric source modes switch to ON by OFF, vehicle actual gear is non-traveling gear, i.e.,
For P gears or N gears；When initial power-on, speed is less than or equal to the first speed threshold value Vps, then actual gear is P gears, vehicle control
Device processed sends P gear locking orders and carries out P gear lockings, ensures that vehicle is in the safe condition of parking；When initial power-on, speed is big
In the first speed threshold value Vps, then it is assumed that when electric under vehicle, vehicle fails to complete P gear locking work, since speed is higher, to protect
It protects P and keeps off latch system, without P gear parking controls, then actual gear is N gears.
In order to ensure that user can be when non-wheeled pattern or whole vehicle state allow to switch to wheeled pattern, user
Vehicle can be moved freely, when user is power-up to ON states, can be kept off by P and switch to N gears, is i.e. user does not have to start vehicle just
It can carry out the switching of P gears and N gears.
When current shift is that P is kept off, kept off if gear request is N, no matter whether vehicle is ready to, stationary vehicle and user steps on
When lower brake pedal condition meets simultaneously, actual gear switches to N gears；Only when brake pedal is stepped on, just allow to be kept off by P to cut
N gears are shifted to, are unexpected movement of the stoppage of vehicle when being unlocked on ramp in order to prevent.
When current shift is that N is kept off, kept off if gear request is P, no matter whether vehicle is ready to, and speed is less than or equal to first
When speed threshold value Vps, actual gear switches to P gears.Just allow to switch to P gears when speed is less than certain threshold value, speed is higher than
Do not allow to switch to P gears when certain threshold value, this is because carrying out P gear parkings when speed is excessively high may be damaged P block locking mechanisms.
Because vehicle is not in wheeled pattern, i.e., when vehicle is unripe, drive system does not allow output torque to carry out
Driving, so when vehicle is unripe, vehicle gear cannot be kept off switching to by P/N can drive gear R/D/S gears；Only vehicle
After being ready to, just allow to keep off switching to by P/N that gear R/D/S can be driven.
When the electric source modes of vehicle are ON and vehicle is in preparedness, kept off for P/N for current shift, gear
The case where request is R gears, when speed is that the conditions such as 0 and user's brake pedal meet simultaneously, actual gear switches to R
Gear；Speed thinks stationary vehicle for 0, at this time user's brake pedal, just allows to switch to R gears so that vehicle is cut from static
When shifting to driving gear, the case where popping out when avoiding the occurrence of vehicle start.When speed is more than 0 and is less than the second speed threshold value
It when Vhs, can shift gears without stepping on braking so that user frequent switching can move forward and backward gear under low speed traveling.When
It is consistent with user's operation gear intention direction if motor direction of rotation is reversion when speed is higher than the second speed threshold value Vhs, then
Allow to switch to R gears；If motor direction of rotation is to rotate forward, do not allow to switch to R gears, forward gear when avoiding high speed and after
Move back gear switching, it is believed that user misoperation.
When the electric source modes of vehicle are ON and vehicle is in preparedness, kept off for P/N for current shift, gear
The case where request is D gears, when speed is that the conditions such as 0 and user's brake pedal meet simultaneously, actual gear switches to D gears；
Speed thinks stationary vehicle for 0, at this time user's brake pedal, just allows to switch to D gears, ensure that vehicle from static switching
When to driving gear, the case where avoiding popping out when vehicle start.When speed is more than 0 and is less than the second speed threshold value Vhs,
It can shift gears without stepping on braking, facilitate user's frequent switching under lower-speed state and move forward and backward gear.When speed height
It is consistent with user's operation gear intention direction if motor direction of rotation is to rotate forward when the second speed threshold value Vhs, then allow to cut
Shift to D gears；If motor direction of rotation is reversion, do not allow to switch to D gears, forward gear and retreating gear when avoiding high speed are cut
It changes, it is believed that user misoperation.
When the electric source modes of vehicle are ON and vehicle is in preparedness, kept off for R for current shift, gear is asked
Ask the case where being kept off for N, no matter speed, brake signal, motor direction of rotation are how many, are directly switch into N gears；When vehicle is in
After ON states and vehicle are ready to, for current shift be D keep off, gear request be N gear the case where, no matter speed, brake signal,
Motor direction of rotation is how many, is directly switch into N gears；After vehicle is in ON states and vehicle is ready to, for working as front
Position is the case where S is kept off, and gear request is N gears, and no matter speed, brake signal, motor direction of rotation are how many, are directly switch into
N is kept off；It ensure that user can switch to N gears at any time.
When the electric source modes of vehicle are ON and vehicle is in preparedness, kept off for D/S for current shift, gear
The case where request is R allows to switch to R gears if speed is 0 and brake pedal；When speed is more than 0 and is less than the second speed
It when threshold value Vhs, can shift gears without stepping on braking, facilitate user's frequent switching under lower-speed state and move forward and backward gear
Position.
When the electric source modes of vehicle are ON and vehicle is in preparedness, kept off for R for current shift, gear is asked
Ask for D the case where, if speed is 0 and brake pedal, allow to switch to D gears；When speed is more than 0 and is less than the second speed threshold
It when value Vhs, can shift gears without stepping on braking, facilitate user's frequent switching under lower-speed state and move forward and backward gear.
When the electric source modes of vehicle are ON and vehicle is in preparedness, kept off for R for current shift, gear is asked
Ask for S the case where, if speed is 0 and brake pedal, allow to switch to S gears；When speed is more than 0 and is less than the second speed threshold
