Abstract

PURPOSE:To minimize a time-lag in the change gear operation performed on the way of a steeply sloping road and the like by supplying an air cylinder with air by a fixed time earlier before a shift head reaches its neutral position in the select operation followed by the shift operation of gear position. CONSTITUTION:Various conditions of a running vehicle, such as shift signal 9, engine speed 13, engine output 14, change gear ratio 15, vehicle running speed 16, present gear position 18 and the like, are input to a computer 23, and these are compared with various types of shift pattern stored beforehand in a fixed memory 21. Subsequently, when the change gear operation is to be performed, the necessity of doing the select operation followed by the shift operation of gear position is judged by means of a judgement circuit 22. In addition, the device is formed in such a manner that, if the select operation is judged necessary, a signal to supply an air cylinder 24 for the select operation with air in order to start pre-load is sent out of the computer 23 by a fixed time earlier before a shift head reaches its neutral position. Consequently, a feeling of physical disorder is no more given to a driver at the time of his change gear operation performed on the way of a sloping road where a quick change of gear is required.

Description

[Detailed Description of the Invention] Technical Field The present invention relates to a remote control method and device for a transmission in a vehicle, and particularly to a method and device for remotely controlling a transmission in a vehicle, and in particular, it eliminates the time lag when performing a gear shift operation accompanied by a select operation while the vehicle is running, and provides a prompt and natural operation. The present invention relates to a method and device that enable gear shifting operations.

PRIOR ART Conventionally, there have been various remote control devices for transmissions that remotely control a transmission located far from the driver's seat of a vehicle using electricity or air, regardless of whether the transmission is mechanically connected to a change lever or a link. This type of device, which is in practical use, consists of a command unit that is placed in the driver's seat and sends out shift signals and select signals by manual operation, and an actuation unit that operates in response to the command signals from the command unit. The transmission is controlled remotely. A change lever is attached to the command unit, and by operating the change lever in the same way as in the case of a direct-coupled type, a shift signal and a select signal are sent out, and a gear change operation is performed from one gear position to another. However, the actuation unit uses air cylinders for shifting and selecting, and depending on the shift pattern, if a select operation is required following a shift operation, the change lever may be placed in the neutral position or very close to the neutral position. Since the select signal was sent out after reaching the position, air starts being supplied to the select air cylinder from this point, so the air pressure of the select air cylinder is activated to produce the specified output. There was a problem in that there was a time lag in the selection operation until the pressure (preload) was reached.

To explain this with reference to FIG. 6, in a transmission with six forward speeds and one reverse speed, four shifter heads 1, 2, .
There are 3 and 4, arrow A.

The direction B indicates the direction of the shift operation, and the directions of arrows C and D indicate the direction of the selection operation. A shift lever 5 is selectively engaged with each shifter head 1 to 4 by a select operation.
It moves from a gear position in the direction (for example, 2nd gear) as shown by arrow E, engages with the shifter head 2, and moves the shifter head in the direction of arrow B to perform a gear shift operation to another gear position (for example, 3rd gear). It indicates the state in the middle of the case. In this case, conventionally, a select signal is issued only after the shift lever 5 reaches the neutral position N or a position very close to the neutral position N in response to a shift signal from a command unit (not shown), and this select signal causes the select air The magnetic valve of the cylinder is opened, air begins to be supplied to the selection air cylinder, and after a predetermined time ΔT has passed, the air pressure in the cylinder reaches the operating pressure P1, and at this point the selection air cylinder is turned off for the first time. It operates and shift lever 5
moves in the direction of arrow E and engages with the shifter head 2. For this reason, when a select operation is required during a shift operation, a time lag of time ΔT cannot be avoided. This is exactly the same when the shifter head 1 moves in the direction of arrow A and reaches the neutral position N in FIG. 6, and then a selection operation is performed.

Purpose The present invention was made in order to eliminate the above-mentioned disadvantages of the prior art, and its purpose is to provide a method and device for remote control of a transmission using electricity or air. When changing gears to a gear position, the computer determines whether or not a select operation is necessary following the shift operation by inputting various conditions under which the vehicle is running into a computer, and if it is determined that the select operation is necessary, , so that when the shifter head reaches the neutral position, the select air cylinder of the transmission operating unit is in a preloaded state capable of producing a predetermined output. By supplying air to the air cylinder, there is no time lag in shifting operations when a select operation is required, and this also makes shifting operations on steep slopes, etc., where a quick gear change is required. The aim is to avoid causing any discomfort.

Configuration: In short, the method of the present invention operates a transmission located far from the driver's seat in response to a command unit located in the driver's seat that sends a shift signal and a select signal by manual operation, and the signals from the command unit. In a method of remote control using an operating unit, the conditions under which the vehicle is running are input into a computer to determine whether or not a select operation is required following a shift operation when shifting from one gear position to another. If it is determined that the select operation is necessary, the select air cylinder of the actuating unit is in a preloaded state capable of producing a predetermined output when the shifter head reaches the neutral position. The present invention is characterized in that air is supplied to the selection air cylinder a predetermined time before the shifter head reaches the neutral position.

The device of the present invention also includes a command unit located in the driver's seat that sends out shift signals and select signals by manual operation, and an operation that operates in response to signals from the command unit, to control a transmission located far from the driver's seat. In a device remotely operated by a unit, the shift signal and select signal, engine rotation speed, engine output,
Various conditions of the vehicle during driving such as gear ratio, vehicle speed, and current gear position are input manually, and the various conditions of the vehicle and the shift pattern are compared with a fixed storage device that stores various shift patterns. a computer having a determination circuit for determining whether or not a select operation is required following a shift operation when changing gears from one gear position to another; The system is characterized in that the computer sends a signal to supply air to the selection air cylinder of the operating unit to start preloading a predetermined time before the shifter head reaches the neutral position. It is.

The present invention will be explained below based on embodiments shown in the drawings. 1st
As shown in FIGS. 5 to 5, a transmission shift operating device 8 according to the present invention operates a transmission (not shown) located far from a driver's seat (not shown) by manual operation. It is a device that is remotely operated by a command unit 11 that sends out a shift signal 9 and a select signal 10, and an actuation unit 12 that operates in response to signals from the command unit, and which controls the shift signal 9, the select signal 10, and the engine speed. 13. Engine output 1
4. A fixed storage device 21 in which various driving conditions 20 of the vehicle such as a gear ratio 15, a vehicle speed 16, a current gear position 18, etc. are inputted, and various shift patterns stored therein, and vehicle conditions 2
0 and a shift pattern to determine whether or not a select operation is required following a shift operation when changing gears from one gear position to another. If a select operation is required following the operation, shifter heads 1, 2.3 and 4
The computer 23 is configured to supply air to the selection air cylinder 24 of the actuating unit 12 a predetermined time ΔT before it reaches the neutral position N, and send out a signal to start preloading. Also, the operating unit 1
2 is provided with a shift air cylinder 25, and a select magnet valve 26 and a shift magnet valve 28 are connected to the select air cylinder 24 and the shift air cylinder 25, respectively. Further, the select magnet valve 26 and the shift magnet valve 28 are connected to the computer 23, and are configured to be opened and closed by signals from the computer.

Note that in FIG. 4, the various conditions 20 while the vehicle is running are not limited to those shown, but include all other necessary information.

Function The present invention is constructed as described above, and its function will be explained below. 1 to 5, for example, when the vehicle is running with the gear position set to 2nd speed, the shifter head 1 shown in FIG. 1 moves in the direction of the arrow, The gear position is set to 2nd speed (3) shown in FIG. In this case, various conditions 20 during running of the vehicle shown in FIG. 4 include, for example, engine rotation speed 13, engine output 14, gear ratio 15, vehicle speed 16,
Information such as the current gear position 18 is input to the computer 23. Therefore, when attempting to shift the change lever (not shown) of the command unit 11 shown in FIG. 3 from the second speed ■ to the third speed ■, first shift from the shift sensor 29 as shown in FIG. A signal 9 is sent out and input into the computer 23. So computer 23
As shown in Fig. 5, the engine speed is 13 and the gear ratio is 1.
5 and a shift signal 30 indicating that a shift is necessary, the vehicle speed and engine output are calculated, and based on the results, the shift operation can be performed from the current gear position, 2nd gear, to any gear position. For example, if the current gear position is G speed, a shift operation of G±1 speed is performed or a shift operation of G±2 speed is performed. to judge. In this case, since all the shift patterns are stored in the fixed storage device W21, the computer 23 reads out one of the shift patterns and determines which gear position will be selected next. The next gear position after 2nd gear is 3rd gear.
If it is the third speed, a signal indicating that the next gear position is the third speed is sent to the determination circuit 22 which determines whether a selection operation is necessary. Then this judgment circuit 2
Step 2 determines whether or not a select operation is required after the shift operation while the shifter head 1 returns to the neutral position N in FIG. The result of that judgment is, for example, N.

If so, the signal to perform the select operation will not be sent out, and the signal to open the select magnetic valve 26 will not be sent out, but in this case, the gear shift operation will be performed from 2nd speed ■ to 3rd speed ■. , the result of that judgment is naturally YES,
While inputting the shift timing signal, the select timing is instructed, and a signal to open the select magnet valve 26 is sent out. Furthermore, this signal is transmitted before the shifter head 5 reaches the neutral position N so that the selection air cylinder 24 of the actuating unit 12 is in a preloaded state in which it can output a predetermined output when the shifter head 1 reaches the neutral position N. The selection magnetic valve 26 is opened so as to supply air to the selection air cylinder 24 earlier by a predetermined time, ie, the time -T shown in FIG. As a result, as shown in FIG.
The air pressure in the select air cylinder 24 increases earlier by T before reaching , that is, -T, and when the shifter head 1 reaches the neutral position N, the select air cylinder 24
The air pressure of the selection air cylinder 24 has increased to the operating pressure of . Therefore, as soon as the shifter head 1 moves in the direction of arrow B and reaches the neutral position N, the selection air cylinder 24 is activated and the selection operation is started without any time lag, and the command unit 1 shown in FIG.
When the driver selects the change lever 1, the operating unit 12 performs the select operation at exactly the same timing, and when the shift lever 5 engages with the shifter head 2 and the select operation is completed, the select sensor 31
A select signal 10, that is, a signal indicating that the selection has been completed, is inputted to the computer 23, and the command unit 1) is sent again to the computer 23.
When the shift operation of 1 is performed toward the 3rd speed (3), a shift signal 9 is input from the shift sensor 29 to the computer 23, and the computer 23 sends a signal to open the shift magnet valve 28, and shifts. The shifter head 2 moves in the direction of arrow B in FIG. ■It is set to.

In addition, in the judgment circuit 22, between the first speed ■ and the second speed ■, between the third speed ■ and the fourth speed ■, and between the fifth speed ■ and the sixth speed ■ in FIG. In the gear shifting operation, the judgment circuit 22 determines that the selection operation is not necessary, so the selection magnet valve 26 is not opened and the selection air cylinder 2
4, air is not wasted.

Furthermore, the gear shifting state in which the determining circuit 22 determines that a selection operation is required occurs similarly when the shifter head 1 moves in the direction of arrow A in FIG. Similarly, a signal is sent to the select magnet valve 26 of the select air cylinder 24 earlier than the neutral position N in the figure by a time equal to ΔT on the right side, and the select magnet valve is opened early (opened), indicating that a select operation is required. At the neutral position N, the selection air cylinder 24 is always ready to reach the preload state.

Furthermore, if the driver performs a gear shifting operation that intentionally misleads the judgment of the computer 23, or performs a peculiar gear shifting operation other than the normal gear shifting operation when driving on a long downhill slope, etc. The shift signal 9 and select signal 10 of the shift sensor 29 and select sensor 31 from the command unit 11 are transmitted to the computer 23.
is given priority, and the opening/closing signals are sent to the select magnetic valve 26 and the shift magnetic valve 28, respectively. Therefore, no matter what kind of speed change operation is performed, there will be no trouble in the device of the present invention.

As described above, according to the method and apparatus of the present invention, when a select operation is performed following a shift operation, the select magnet valve 26 is opened before the shifter heads 1 to 4 reach the neutral position N, and the select operation is performed. air cylinder 2
4 is in the preload completion state, the time lag of the select operation becomes O, and for example, when a sightseeing bus or the like goes up a steep slope, a speed change operation is performed quickly, and there is no smell of such quick operation. The discomfort disappears.

Effects Since the present invention is configured and operates as described above, in the remote control method and device for a transmission using electricity or air, when shifting from a certain gear position to another gear position, Following the operation, the computer determines whether or not a select operation is necessary by inputting the various conditions under which the vehicle is running, and if it is determined that the select operation is necessary, the transmission is activated when the shifter head reaches the neutral position. Air is supplied to the select air cylinder of the operating unit a predetermined amount of time earlier than the shifter head reaches the neutral position so that the select air cylinder of the operating unit reaches a preloaded state capable of producing a predetermined output. This has the excellent effect that there is no time lag in gear shifting operations when a select operation is required, and as a result, there is no discomfort in shifting gears on steep slopes that require quick gear changes. It will be done.
