The embodiment of the present invention is described below in detail, examples of the embodiments are shown in the accompanying drawings, wherein from beginning to end
Same or similar label indicates same or similar element or element with the same or similar functions.Below with reference to attached
The embodiment of figure description is exemplary, it is intended to is used to explain the present invention, and is not considered as limiting the invention.
With reference to the accompanying drawing come describe the embodiment of the present invention automobile shift control method, device and its equipment.
Fig. 1 is the flow diagram according to the shift control method of the automobile of one embodiment of the invention.As shown in Figure 1,
The shift control method of the automobile the following steps are included:
Step 101, current shift information is obtained.
Step 102, shift knob position information is obtained.
Specifically, the shift control method of the automobile of the embodiment of the present invention is applied to homing position type electric gear change control system,
Fig. 2 is the structural schematic diagram according to the homing position type electric gear change control system of one embodiment of the invention.
As shown in Fig. 2, the homing position type electric gear change control system includes: homing position type electric gear change control unit ESK, vehicle
Control unit VCU, P keep off control unit PCU and instrument display unit ICM.
It should be noted that homing position type selector is self-replaced type knob selector, changed on control panel including knob
Keep off sensor, S gear push button signalling, P gear push button signalling and gear indicator light.
Wherein, knob gear shift sensing device can respectively rotate two strokes to the left and to the right, and S gear key can be pressed.ESK acquisition
Knob gear shift sensing device, S gear push button signalling and P keep off push button signalling, and are sent to entire car controller by CAN message；Gear refers to
Show that lamp includes tetra- gears of P, R, N, D, S, ESK lights gear indicator light according to actual gear signal.
Further, the signals such as the comprehensive driver's operation of entire car controller, speed, brake signal, motor direction of rotation are sentenced
The disconnected gear shift operation demand for whether responding user, provides actual gear signal, actual gear signal is sent to by CAN message
ESK and instrument.When entire car controller determines gear failure, malfunction is issued by CAN.
Specifically, instrument shows tetra- gears of P, R, N, D, S, is shown according to actual gear signal to carry out gear.When whole
When vehicle determines gear failure, show that gear failure is given driver and reminded by instrument.P: pool (stopping) car stop --- after vehicle stops
Needing to hang over this gear can just pull key；N: neutral gear；D: drive shift, when normal driving, hang over this shelves；R: reverse gear；L: low speed
Gear shift；S: motor pattern.
Specifically, in practical applications, ESK is responsible for current shift request identification.Wherein, homing position type selector setting resets
Formula shift knob, S gear key and P keep off key, and S gear key is kept off for D and S keeps off switching control, and D keeps off and represents Economy urge factor gear, S
Gear represents movement driving gear；P gear represents parking gear；
Wherein, there are five positions for homing position type shift knob, are divided into origin position, and knob respectively has to the left, to the right two sections of strokes,
To the left or to the right after rotation, knob is unclamped, knob rotates back to origin position automatically, and user's operation is passed through electronic gear shifter by ESK
Gear request message is sent to VCU.
Therefore, one of available current gear information, such as tetra- gears of P, R, N, D, S, and according to reset
Formula shift knob determines shift knob position information, such as in origin position, left-handed stroke and dextrorotation stroke etc..
Step 103, judge that current shift is requested according to shift knob position information and current shift information.
Step 104, shift control is carried out according to current shift request.
It specifically, can be according to shift knob position letter after obtaining current shift information and shift knob position information
Breath and current shift information judge that current shift is requested.
It is understood that different current shift information and shift knob position information can determine it is different current
Gear request, is illustrated below:
The first example, when current shift information is that P/N/D/S is kept off, knob position information of shifting gears is left-handed stroke 2 gear
When, judge current shift request for R gear.
It should be noted that no matter whether S gear key is pressed, whether P gear key is pressed, forward gear memory state is D gear
Or S gear, front is worked as in judgement when current shift information is P/N/D/S gear, shift knob position information is left-handed stroke 2 gear
Position request is that R is kept off.User, which rotates shift knob to left side second stroke (2 grades) from N gear, just switches to R gear, rather than the first row
Journey is that user misoperation carries out gear shift operation in order to prevent, and rotation just allows to shift gears more specify changing for user to second stroke
Gear is intended to.
Second of example, when current shift information is that P/R/D/S is kept off, shift knob position information is left/right rotating journey 1
When gear, judge current shift request for N gear.
It should be noted that no matter whether S gear key is pressed, whether P gear key is pressed, forward gear memory state is D gear
Or S gear, 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 operation shift knob, either
It turns left or toward right rotation short stroke, gear request switches to N gear.
It should be noted that gear request is defaulted as P gear when vehicle initial power-on, user rotates shift knob to a left side
Lateral incision shifts to R gear, is to guarantee the habit of user's operation to be consistent with existing rotation shift control.
Further, shift control is carried out according to current shift request.That is after ESK judges current shift request, VCU is negative
Blame actual gear control.As an example, believed according to current gear request, current gear information, braking information, electric source modes
Breath, vehicle speed information and motor direction of rotation determine actual-gear, carry out shift control according to actual-gear.
In conclusion the shift control method of the automobile of the embodiment of the present invention, by obtaining current shift information and shift
Knob position information, and judge that current shift is requested according to shift knob position information and current shift information, last basis is worked as
Preceding gear request carries out shift control, so as to quickly correct identification current shift request, carries out actual gear control, avoids
The problem of gear faulty operation, improve the convenience and safety that automobile uses.
It based on the above embodiment, after step 102, further include obtaining selector setting information.Thus, it is possible to according to changing
Gear knob position information, selector setting information and current shift information judge that current shift is requested.It is illustrated below:
The first example, when current shift information is D gear, shift knob position information is origin position, and selector is set
When confidence breath is that S gear key is pressed and P gear key is not pressed, judge current shift request for S gear.
Second of example, when current shift information is S gear, shift knob position information is origin position, and selector is set
When confidence breath is that S gear key is pressed and P gear key is not pressed, judge current shift request for D gear.
Specifically, when current shift is that D is kept off, ESK, which is detected, shifts gears knob in origin position, and S is kept off key by user
When pressing, current shift request is that S is kept off；When current shift is that S is kept off, ESK, which is detected, shifts gears knob in origin position, and user
When by S gear by key pressing, current shift request is that D is kept off.Switching between D gear and S gear keeps off key by S to realize, is not used
Rotation shift switching, greatly reduces the complexity of shift control method, is switched mutually by S gear key by D gear and S gear, full
Demand of the foot user in Economy urge factor gear and movement driving gear switching.
Therefore, the switching between D gear and S gear keeps off key by S to realize, rotation shift switching is not used, greatly reduces
The complexity of shift control method keeps off key by D gear and the switching mutually of S gear by S, meets user in Economy urge factor gear
With the demand of movement driving gear switching.
The third example, when current shift information is R/N/D/S gear, shift knob position information is origin position, and P is kept off
When key is pressed, judge current shift request for P gear.
Specifically, when current shift is that R/N/D/S is kept off, ESK detects shift knob in origin position, and user is by P
When gear is by key pressing, no matter whether S gear key is pressed, forward gear memory state is D gear or S gear, and gear request is that P is kept off.
Therefore, parking gear enters through P gear key to realize, rotation shift switching is not used, greatly reduces shift control
The complexity of method processed meets the shift demand of user's parking and traveling.
It based on the above embodiment, after step 102, further include obtaining forward gear memory state.
It should be noted that user can exist according to drive demand since forward range is divided into D gear and S two gears of gear
It is switched between two gears, so the forward gear state selected user is needed to remember.Before guaranteeing that user switches to
Into when keeping off, gear request selecting is forward gear memory state, and user does not have to select the forward gear of oneself to operate S gear again and press
Key reduces the unnecessary operation of user.
Specifically, " forward gear memory state " is set, when initial power-on, " forward gear memory state " is that D is kept off；It has initialized
Cheng Hou, if actual gear switches to S gear, " forward gear memory state " is S gear；If actual gear switches to D gear, " advance
Keep off memory state " it is that D is kept off.When being in other actual gears, user's operation S keeps off key, is considered as invalid operation, " forward gear note
Recall state " initial value is kept, do not switch forward gear memory state.
Specifically, the forward gear state of user's selection is remembered, remembers the driving habit of user, user do not have in order to
It selects the forward gear of oneself to operate S gear key again, reduces the unnecessary operation of user, improve driving experience.
Thus, it is possible to be judged according to forward gear memory state, shift knob position information and current shift information current
Gear request.It is illustrated below:
The first example, when forward gear memory state be D gear, current shift information be P/R/N keep off, and shift knob position
When information is that dextrorotation stroke 2 is kept off, judge current shift request for D gear.
Specifically, when current shift is that P/R/N is kept off, ESK detects that user turns right shift knob rotation direction to second stroke
When, no matter whether S gear key is pressed, whether P gear key is pressed, if forward gear memory state is D gear, current shift request
For D gear.
Second of example, when forward gear memory state be S gear, current shift information be P/R/N keep off, and shift knob position
When information is that dextrorotation stroke 2 is kept off, judge current shift request for S gear.
Specifically, when current shift is that P/R/N is kept off, ESK detects that user turns right shift knob rotation direction to second stroke
When, no matter whether S gear key is pressed, whether P gear key is pressed, if forward gear memory state is S gear, current shift request
For S gear；
Wherein, user, which rotates rotator to right side, switches to forward gear, is to shift gears to control with existing rotation and keep
Unanimously, guarantee the habit of user's operation.
Thereby it is ensured that left-handed stroke two is R gear, dextrorotation stroke two is that D is kept off, and rotating left and right short stroke is that N is kept off, and is specified
The corresponding gear request of each rotating distance, greatly reduces the complexity of user's operation.
Specifically, when driver operates gearshift, entire car controller interprets driver's gear by identification gear information
Position demand, and show gear information to prompt driver by the indicator light in instrument and position retaining device panel.Work as full-vehicle control
When device determines gear failure, show that gear failure is given driver and reminded by instrument.ESK is responsible for gear request identification, and VCU is negative
Blame actual gear control.
How to judge that current gear is requested in order to which those skilled in the art are more clearly intuitively above-mentioned, specifically below with reference to table 1
It is bright.Specifically, ESK is according to current shift information, shift knob position information, forward gear memory state, selector setting information
Comprehensive descision show that current shift is requested, and is sent to VCU by CAN.Current shift requests decision logic as shown in table 1:
1 gear of table requests decision logic
It should be noted that homing position type selector can be rotated back to automatically after user's operation shift by user's operation stroke
Origin position, the i.e. request of shift gear are instantaneous state.Assuming that entire car controller VCU does not respond the request of user's gear, gear is asked
Win is asked to switch to former gear.Carry out gear shift operation, gear request changes, ESK will new gear request issue after start into
Row timing, if actual gear is switched to gear request unanimously, then gear request is protected in gear request effective time threshold value
It holds；If actual gear and gear request are inconsistent after gear requests effective time threshold value, then gear request switches to former gear
Position request.
Based on the above embodiment, in order to which those skilled in the art are more clear how according to current gear request, current gear letter
Breath, braking information, electric source modes information, vehicle speed information and motor direction of rotation determine actual-gear, are carried out according to actual-gear
Shift control.
Specifically, current gear request, current gear information, braking information (whether stepping on braking), electric source modes information (on
Power on, ready state), vehicle speed information (speed), motor direction of rotation be described as follows below with reference to table 2:
2 actual gear decision logic of table
Specifically, under vehicle power-down state (i.e. electric source modes are OFF), when user powers on, vehicle IG1 electricity is attracted,
Vehicle low pressure powers on, and electric source modes are ON electricity by OFF at this time；If user is under the electric source modes such as OFF/ON electricity, user steps on simultaneously
Brake pedal is powered on, vehicle can the above high-voltage electricity, into travelable mode, i.e. Ready state.
Specifically, when vehicle initial power-on, i.e., when electric source modes switch to ON gear electricity by OFF, vehicle actual gear is non-
Drivable position, as P gear or N gear；When initial power-on, speed is less than or equal to Vps, then actual gear is P gear, full-vehicle control
Device VCU sends P gear locking order and carries out P gear locking, guarantees that vehicle is in the safe condition of parking；When initial power-on, speed
Greater than Vps, it is believed that when electric under vehicle, vehicle fails to complete P gear locking work, since speed is higher, keeps off locking system for protection P
System, without P gear parking control, then actual gear is N gear.
In order to guarantee that user can be when non-travelable mode or whole vehicle state allow to switch to travelable mode, user
Vehicle can be moved freely, when user is power-up to ON electricity, can be kept off by P and switch to N gear, is i.e. user does not have to start vehicle can
To carry out the switching of P gear and N gear.
Specifically, current shift be P keep off when, if gear request be N keep off, no matter vehicle whether Ready, stationary vehicle and
When condition meets simultaneously when user's brake pedal, actual gear switches to N gear；Only when brake pedal is stepped on, just permit
Perhaps N gear is switched to by P gear, is unexpected movement of the stoppage of vehicle when being unlocked on ramp in order to prevent.
It should be noted that the electricity under the user's operation key, and when gear not being switched to parking gear, if speed allows,
It can be automatically controled vehicle parking, keep vehicle in a safe condition.
Specifically, current shift be N keep off when, if gear request be P keep off, no matter vehicle whether Ready, speed be less than etc.
