Detailed Description
In order that the above-recited objects, features and advantages of the present invention will become more readily apparent, a more particular description of the invention will be rendered by reference to the appended drawings and appended detailed description. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the scope of the invention.
Referring to FIG. 1, a flowchart of a method for implementing a shift based on an automated manual shifter, which is a self-resetting electronic shifter, is shown in an embodiment of the present invention, the method comprising:
step 101: a status signal of the unlock button is received.
In the embodiment of the invention, the manual-automatic integrated gear shifter is a self-resetting electronic gear shifter, and the self-resetting electronic gear shifter refers to: after the gear lever is shifted forwards or backwards, the gear lever automatically returns to the middle position. In general, an automobile adopting an automatic manual shifter defaults to an automatic gear mode, the gear is at the P gear when the automobile is stopped, and after the automobile is started, a user is shifted to the R gear, the N gear, the D gear or the M gear according to the self requirements. Because of the self-resetting electronic gear shifter, the gear lever returns to the middle position after each gear is engaged.
If the user needs to drive in the automatic gear mode, the user can not engage in the M gear after engaging in the D gear, and when the user needs to drive in the manual gear mode, the user engages in the M gear after engaging in the D gear, so that the vehicle enters in the manual gear mode.
In manual mode, the transmission is in manual gear, but the lever is returned to neutral after shifting. At this point a status signal of the unlock button is received.
Step 102: a position signal is received from the reset electronic shifter.
In the embodiment of the invention, the state signal of the unlocking button is received, and the position signal of the self-resetting electronic gear shifter is also required to be received so as to prepare for the subsequent gear shifting operation.
Step 103: in the case where the gear of the vehicle transmission is in the manual gear, a shift operation is performed according to the state signal, and the position signal to achieve a shift of the vehicle.
In the embodiment of the invention, after the vehicle enters the manual gear mode, the transmission assembly knows that the gear of the current transmission is in the manual gear, and then the transmission assembly is combined with the received state signal of the unlocking button and the received position signal of the self-resetting electronic gear shifter to obtain the gear shifting operation required by the user, so that the gear shifting operation is carried out, and the gear shifting of the vehicle is realized.
In actual operation, the position signal includes: a forward position signal, a backward position signal; according to the state signal of the unlocking button and the position signal of the self-resetting electronic gear shifter, the specific steps include:
step S1: performing a downshift operation when the state signal is an unpressed state signal and the position signal is a forward position signal;
step S2: in the case where the state signal is an unpressed state signal and the position signal is a rearward position signal, an upshift operation is performed.
In the embodiment of the invention, if the state signal of the unlocking button is a non-pressed state signal and the position signal of the self-resetting electronic gear shifter is a forward position signal, the transmission assembly performs a gear shifting operation. When the vehicle is in the manual gear mode, the user directly dials the gear lever forward without pressing the unlocking button, so that the gear is shifted down, and after the gear lever returns to the middle position, if the user dials the gear lever forward again, the gear is shifted down again.
If the state signal of the unlocking button is an unpressed state signal and the position signal of the self-resetting electronic gear shifter is a backward position signal, the transmission assembly performs an upshift operation. When the vehicle is in the manual gear mode, the user directly dials the gear lever backwards without pressing the unlocking button, the gear is shifted upwards, and after the gear lever returns to the middle position, if the user dials the gear lever backwards again, the gear is shifted upwards again.
In fact, the gear lever of the self-resetting electronic gear shifter is shifted forward by two positions, namely shifting one position signal forward and shifting two position signals forward; it will be appreciated that the distance of the lever to dial one position forward from the neutral position is less than the distance to dial two positions forward from the neutral position, and naturally, there are two positions to dial back, one position signal to dial back and two position signals to dial back; it will be appreciated that the distance by which the lever toggles one position back from the neutral position is less than the distance by which the lever toggles both positions back from the neutral position.
In the case that the status signal of the unlocking button is an unpressed status signal, i.e. the user does not press the unlocking button, if the user dials forward, both dial forward and dial forward one position, the user will downshift, and neither dial one position nor two positions. Similarly, the backward shift up is the same, and the user does not press the unlocking button, so long as the user shifts backward, the user does not distinguish between shifting one position and two positions.
And under the condition that the user presses the unlocking button, the specific steps of the gear shifting operation according to the state signal of the unlocking button and the position signal of the self-resetting electronic gear shifter comprise the following steps:
step T1: in the case where the state signal is a pressing state signal and the position signal is a rearward position signal, the gear position of the vehicle transmission is switched from the manual gear to the automatic gear.
In the embodiment of the invention, if the state signal of the unlocking button is a pressing state signal and the position signal of the self-resetting electronic gear shifter is a backward position signal, the transmission assembly switches the gear of the vehicle transmission from a manual gear to an automatic gear. When the unlocking button is pressed by a user, the gear lever is directly shifted backward, no matter one position is shifted backward or two positions are shifted backward, the gear of the transmission of the vehicle is switched from the manual gear to the automatic gear, namely, the vehicle exits from the manual gear mode and enters into the automatic gear mode. And then the user performs corresponding operation according to the automatic gear mode, and when the user needs to enter the manual gear mode again, the user can engage in gear to M gear.
Step T2: in the case where the state signal is a press state signal and the position signal is a dial-forward one position signal, the gear of the vehicle transmission is shifted from the manual gear to the neutral gear.
Step T3: when the state signal is a pressing state signal and the position signal is a dial-forward two-position signal and a brake signal is received, the gear of the vehicle transmission is switched from a manual gear to a reverse gear.
In the embodiment of the invention, if the state signal of the unlocking button is a pressing state signal and the position signal of the self-resetting electronic gear shifter is a forward shifting position signal, the transmission assembly shifts the gear of the vehicle transmission from a manual gear to a neutral gear. When the vehicle is in the manual gear mode, the user pushes the unlocking button and simultaneously dials the gear lever forwards by one position, so that the gear of the transmission of the vehicle is switched from the manual gear to the neutral gear, and at the moment, the vehicle automatically exits from the manual gear mode and enters into the automatic gear mode.
If the state signal of the unlocking button is a pressing state signal, the position signal of the self-resetting electronic gear shifter is a forward shifting two position signals, and meanwhile, a brake signal is also received, and the transmission assembly switches the gear of the vehicle transmission from a manual gear to a reverse gear. When the vehicle is in the manual gear mode, the user presses the unlocking button and simultaneously pushes the brake and dials the gear lever forwards to two positions, so that the gear of the transmission of the vehicle is switched from the manual gear to the reverse gear, and at the moment, the vehicle automatically exits from the manual gear mode and enters into the automatic gear mode. Thus, the vehicle transmission is ensured not to directly change from M gear to reverse gear and damage the gears.
When the vehicle is in a parking state, the vehicle transmission assembly switches the gear of the vehicle transmission from the manual gear to the parking gear. When the vehicle is in the manual gear mode, after the user controls the vehicle to stop running, the parking button (or the hand brake) is pressed, the gear of the transmission of the vehicle is switched from the manual gear to the parking gear, and at the moment, the vehicle automatically exits the manual gear mode and enters the automatic gear mode. For example: the first preset value is 2km/h, then the vehicle transmission assembly switches the gear of the vehicle transmission from the manual gear to the park gear when the park signal is received and the vehicle speed of the vehicle is below 2km/h with the gear of the vehicle transmission in the manual gear.
Of course, it is understood that when the park signal is received and the vehicle speed is below the first preset value with the gear of the vehicle transmission in the automatic gear, the vehicle transmission assembly will also shift the gear of the vehicle transmission from the automatic gear to the park gear.
The method for realizing gear shifting based on the manual-automatic integrated gear shifter combines the schematic diagram of the self-resetting electronic gear shifter shown in fig. 2, wherein one preferable realization method is as follows:
in fig. 2, in order to clearly explain a preferred implementation method of the present invention, a black triangle is used to indicate the direction of shifting the lever, X indicates the middle position of the lever, F1 indicates one position of shifting the lever forward, F2 indicates two positions of shifting the lever forward, B1 indicates one position of shifting the lever backward, and B2 indicates two positions of shifting the lever backward, and on an actual vehicle, no indication is given to X, F1, F2, B1 and B2, but only the indication is given to P (parking gear), R (reverse gear), N (neutral gear), D (automatic gear) and M (manual gear).
One possible schematic diagram of a self-resetting electronic shifter for an actual vehicle in the dashed box 10 of fig. 2, the positions of D-gear and P-gear are intermediate positions of the gear lever, and the transmission assembly determines the current actual gear of the transmission according to the current state of the vehicle and the operation of the user. When the vehicle starts, after the vehicle is shifted to the D gear, the gear lever is directly shifted backwards, and the vehicle can enter a manual gear mode no matter the vehicle is shifted to the B1 position or the B2 position, the gear of the transmission is a manual gear, and the gear is denoted by M in a broken line frame 10 of FIG. 2.
When entering manual mode, the user does not press the unlock button and directly dials forward the lever, either to the F1 position or to the F2 position, which is a downshift operation in manual mode, once for every downshift, as indicated by M-in dashed box 30 of FIG. 2. The user does not press the unlocking button, and directly dials the gear lever backwards, and the gear lever is in an upshift operation in a manual gear mode no matter the gear lever is toggled to the B1 position or the B2 position, and the gear is upshifted once when the gear lever is toggled once, as shown by M+ in a dashed line box 30 in fig. 2.
When entering manual gear mode, the user presses the unlock button and simultaneously dials the lever rearward, either to the B1 position or to the B2 position, to change from manual gear mode to automatic gear mode, the gear of the transmission changing from manual gear to automatic gear, as shown by D in dashed box 20 of fig. 2. While the user presses the unlock button while pulling the lever forward by one position, i.e., after pulling the lever to the F1 position, releasing the lever no longer forward, the gear of the transmission changes from manual gear to neutral, and exits the manual gear mode to enter the automatic gear mode, as shown by N in dashed box 20 of fig. 2; if the user presses the unlock button while stepping down the brake and pulling forward the lever, i.e., pulling the lever to the F2 position and then releasing the lever, the gear of the transmission is changed from manual gear to reverse gear and exits the manual gear mode to enter the automatic gear mode, as indicated by R in dashed box 20 of fig. 2. In the dashed box 20 of fig. 2, the depression of the unlocking button is indicated by a black dot, and the depression of the brake is indicated by a black pentagonal star.
In summary, according to the method for implementing gear shifting based on the manual-automatic gear shifter provided by the embodiment of the invention, after entering the manual gear mode according to the conventional method, the state signal of the unlocking button on the gear shifter is received, and the position signal of the self-resetting electronic gear shifter is also received, and under the condition that the gear of the vehicle transmission is in the manual gear, the gear lifting operation in the manual gear mode, the automatic gear returning operation, the neutral gear entering operation and the reverse gear entering operation are performed according to the state signal of the unlocking button and the position signal of the self-resetting electronic gear shifter. The gear shifting sheet is not needed to realize the lifting gear operation, the M gear structure is not needed, mechanical parts are fewer to a certain extent, the cost is naturally reduced, and the weight of the whole vehicle is reduced.
