Description

[Detailed Description of the Invention] The present invention relates to a device for simulating the actual driving condition of an automobile, and particularly relates to a transmission ratio command device for controlling the mission position by giving a command to a mission operating device that changes the transmission position. .

The mission ratio command device sets the mission lever positions corresponding to various mission ratios, such as neutral N, 1st gear, 2nd gear, etc., to the left, middle, right, master, front, When determining by a combination of middle and rear positions, this is a device that generates a first type of signal that determines the left and right positions, and a second type of signal that determines its front and rear positions.

A mission ratio command device is used to apply the signal generated in this manner to a mission operating device (not shown), and cause the operating device to drive a mission lever to change the mission ratio.

In FIG. 1, there are four types of first type signals and three types of second type signals, so by combining them, a total of one additional type of mission ratio (including neutral) can be obtained.

By the way, this type of mission ratio command device requires a device on the command side that converts seven types of commands into signals of 4 types x 3 types = 1 additional type, and this will be called an encoder.

Furthermore, on the detection side, a device is required that converts one type of answer signal into seven types of answer signals, and this will be called a decoder.

Conventionally, such a mission ratio command device having both an encoder and a decoder has been constructed using either (1) a method using a diode pin board or (2) a method using a plurality of digital switches.

However, in method (1), the setting status cannot be determined at a glance by looking at the pin board, and therefore, it is unavoidable that it is inconvenient in operation.

The method (2) requires a huge circuit network to be wired to the switch, is expensive, and has the drawback of taking up a large amount of space.

Another possible method is to use two rotary switches, but while this simplifies the circuit network, it is expected that the development of such a switch would be necessary and the space would be large. When you think about it, it can be said that it is not practical.

In view of the above points, the present invention provides a mission ratio command device that is inexpensive, compact, and allows the so-called setting state to be recognized at a glance.

FIG. 2 is a circuit diagram showing an embodiment of the present invention, and in the figure,
T1-T1° is a command side collective terminal that has a mission ratio command transmission terminal and a mission ratio answer signal reception terminal provided corresponding to various mission ratios from neutral N to 11th speed, and the collective terminals T1 to The large circle in T1□ is the mission ratio command transmission terminal on the encoder side.
The small circle is the mission ratio answer signal receiving terminal on the decoder side.

T13-T2. is configured to correspond to the mission lever position shown in FIG. 1, and is one-to-one with the command collection terminals T1 to T1°, for example, by a single plug 1 having two line terminals as shown in FIG. Of the relay collective terminals T13 to T24, the large circle is connected to the mission ratio command transmission terminal by plug 1, and is a command relay terminal on the encoder side, and the small circle is the relay terminal connected to the mission ratio command transmission terminal. Ratio answer signal receiving terminal and plug 1
This is an answer signal relay terminal connected to the decoder side.

Each command relay terminal is branched into two lines, one branch line is connected to the first type mission positioning signal transmission terminals 01 to C4 via diodes D□ to D1□, and the other branch line is also connected to the first type mission positioning signal transmission terminals 01 to C4. Diode D in the same direction.

~D24 to the second type mission positioning signal transmission terminals C5 to C7.

Here, the first type of mission positioning signal transmission terminal C1
~C4 correspond to the left, middle, right, and master positions of the mission lever, respectively, and second type mission positioning signal transmission terminals q~C7 correspond to the front, middle, and rear positions of the mission lever, respectively.

Note that the signals transmitted from these terminals 01 to C7 move a mission lever of a mission operating device (not shown) to a predetermined position, thereby changing the mission position.

On the other hand, each of the answer signal relay terminals includes a first type of mission position answer signal transmission terminal A□ to which an answer signal indicating the current left and right position of the mission lever is transmitted.
Any one of the terminals A4 and any one of the second type mission position answer signal transmission terminals A5 to A7 from which an answer signal indicating the front and rear positions is transmitted are connected to the NAND circuit N. Connected via Ni2.

Next, the operation will be explained.

For example, the mission ratio for 5th gear is 1st gear is front left, 2nd gear is rear left,
If the 3rd gear is the middle cylinder, the 4th gear is the middle diameter, and the 5th gear is the right front, prepare five plugs 1 (see Figure 3).

First, to set the transmission to 1st speed, the command side collective terminal T2
and the relay collective terminal T13 are connected using today's plug 1.

As a result, the mission ratio command signal passes through the mission ratio command transmission terminal and the command relay terminal, and further passes through the diode D.
The signal is transmitted to the first type of mission positioning signal transmission terminal C1 and the second type of mission positioning signal transmission terminal through the terminal and D□3.

Signals transmitted from the terminals C1 and q are supplied to a mission operating device (not shown).

The mission operating device drives the mission lever based on the supplied signal.

This moves the transmission lever to the left, forward position.

Assuming that the transmission is securely in the first gear position, an answer signal indicating the mission lever position is supplied to the first type of mission position answer signal transmission terminal A1 and the second type of mission position answer signal transmission terminal. Only the NAND circuit N1 provided upstream of the relay collective terminal T13 is operated.

(The signal from Al is also supplied to other NAND circuits N5*N9, and the signal from A5 is also supplied to other NAND circuits N2.
N3. Also supplied to N4.

) The output of this NAND circuit N1 is sent to the answer signal receiving terminal of the command side collective terminal T2 via the answer signal relay terminal of the relay collective terminal T13.

This allows the current mission position to be recognized.

After confirming from the answer signal that the mission is in the current mission position, that is, the 1st gear position,
Next, to change the transmission to 2nd speed, connect terminals T3 and T21 with the same plug as above.

As a result, mission positioning signals are transmitted from terminals C4 and 07 in the same manner as described above.

The transmission signal causes the mission operating device to drive the mission lever, move the lever to the left and rear, and shift the transmission to second gear.

Thereafter, if an answer signal arrives at terminal T3 in the same way, 3
Prepare to shift the transmission position to 3rd gear using today's plug.

The answer signal is sent to terminal T4. T5. By arriving at T6, the mission position can be reliably recognized.

Note that the connection between the command side collective terminal and the connecting means such as a plug may be detachable or may be fixed, that is, directly connected.

Similarly, depending on the case, it is possible to fix the connection to the relay collective terminal as well.

In addition, depending on the type of mission ratio, the collective terminal on the command side,
Of course, the number of relay collective terminals or mission positioning signal transmission terminals may be increased or decreased.

As explained above, according to the present invention, a desired mission ratio can be set using a single connection means (for example, a plug or jack) having two line terminals, so that the setting state can be maintained in an orderly manner. It becomes possible to identify at a glance what state the system is in, and the operability is significantly improved when creating combinations of various aspects.

Furthermore, since the wiring and parts used are simple and compact, an inexpensive and compact device can be obtained.
