判別する変速装置の変速モード判定方法に関する。[Detailed Description of the Invention] [Field of Industrial Application] The present invention provides a gear shift system that determines the gear stage of a main transmission with an auxiliary transmission based on the engine rotational speed, vehicle speed, and gear stage of the auxiliary transmission. The present invention relates to a method for determining a gear shift mode of a device.
変速レバーを手で動かしてシフトチェンジする手動式の
主変速機に、走行状況に見合って自動変速される副変速
機を付加した変速装置において。A transmission system that has a manual main transmission that changes gears by manually moving the gear lever, and an auxiliary transmission that automatically changes gears according to driving conditions.

７に伝達される。For example, the transmission 1 shown in FIG.
A one-way clutch 3a is installed in the power transmission path upstream of the main transmission 2, which has speed change gears 21, 22, 23, and 24.
A sub-transmission 3 is provided in which a low speed gear with a hydraulic clutch 3b and a high gear gear with a hydraulic clutch 3b are connected in parallel, and the engine 5
The power is transmitted to the axle 7 via the foot clutch 6° transmission 1.

油圧クラッチ３ｂが接続されたときに、副変速機３は低
速段から高速段に切り換わる。The one-way clutch 3a of the sub-transmission 3 transmits power from the engine 5 side to the axle 7 side, but has the function of cutting off power transmission from the axle 7 side to the engine 5 side, and its operation is as follows. While everything depends on the force relationship between the load and the transmitted power, the hydraulic clutch 3b is intermittent controlled by commands from a microcomputer (not shown) in the control circuit 8.
When the hydraulic clutch 3b is connected, the sub-transmission 3 switches from a low gear to a high gear.
このため、変速装置１は、主変速機２の第２速から第４
速までが、副変速機３の状態に応じてそれぞれ高速段と
低速段の２通りの区別があり、この区別のない第１速を
含めると、第４図に１，２Ｈ，３Ｌ、３Ｈ，４Ｌ、４Ｈ
と示す如く、全体として７段階の変速比が存在すること
になる。Therefore, the transmission 1 shifts from the second gear to the fourth gear of the main transmission 2.
There are two different speeds, high speed and low speed, depending on the state of the auxiliary transmission 3, and if the first speed, which has no distinction, is included, Fig. 4 shows 1, 2H, 3L, 3H, 4L, 4H
As shown, there are seven speed ratios in total.
なお、制御回路８による副変速機３の切り換えは、車両
の走行状況に応じて自動的に行われるが。Note that switching of the sub-transmission 3 by the control circuit 8 is automatically performed depending on the driving situation of the vehicle.

ル開度等にもとづいて１判断される。The running condition of this vehicle is determined by the output of a rotation sensor 10 for detecting the engine rotation speed attached to the ignition coil 9, and by the magnetic disk 11a at the tip of the rotation transmission shaft 7a connected to the axle 7 and the magnetic disk II aζ. Thus, a determination is made based on the output of the vehicle speed sensor 11 consisting of the reed switch 11b that is opened and closed, or the throttle opening as an index of the engine load.

There is a method of determining the gear position by knowing the gear ratio of In some cases, even if you only know the relationship between the engine speed Ne and the vehicle speed V, it may be true that the main transmission 2 is in the 4th gear and the auxiliary transmission 3 is in the lower gear (4th gear).
It may be difficult to distinguish between shift mode (L) and the driver may misjudge the shift position. There were problems such as the setting of the gear ratio of the transmission 2 and the sub-transmission 3 being limited to a very narrow range.

定するようにしたことを要旨とするものである。Power is transmitted from the engine to the axle through the main transmission, which selects the gears by manual operation, and the sub-transmission, which automatically selects the lower two gears based on commands from the control circuit. The speed change mode of the transmission device is set to the main transmission based on the gear ratio and the gear position of the auxiliary transmission determined from the ratio of the output of the rotation sensor that detects the engine rotation speed and the output of the vehicle speed sensor that detects the vehicle speed. The gist of this is that the gear position is determined and a 1 determination is made.

。In FIG. 1, reference numeral 32 denotes a gear stage discrimination circuit provided within the control circuit 8 that controls the hydraulic clutch 3b of the sub-transmission 3 on and off. This gear position determination circuit 32 determines the gear position of the main transmission 2 based on three pieces of information: the vehicle speed V, the engine rotation speed N, and the gear position of the auxiliary transmission 3. Vehicle speed V and engine rotation speed Ne are determined by vehicle speed sensor 11 and rotation sensor l as before.
detected by O. Since the gear stage of the sub-transmission 3 is determined by the control circuit 8 itself, no special detection means is required.

回転数Ｎｅにもとづいて、ステップれる。Here, the gear ratio of the transmission 1 is determined according to the ratio of the rotation speed of the engine 5 and the rotation speed of the axle 7. That is, in the operation program shown in FIG. 2, steps (101),
Steps are performed based on the vehicle speed V and engine speed Ne read in (102').

どうかが判断される。Step (103) is followed by judgment steps (104) and (105) for determining the gear position of the main transmission 2, and in step (104), the gear position is uniquely determined from the gear ratio K. In other words, it is determined whether or not the point determined by the vehicle speed V and the rotational speed Ne in the coordinate system shown in FIG. 4 is included in a portion other than the shaded portion in the figure.

As a result of the first judgment, if it is found that the sub-transmission 3 is in a high gear position, step (107) is carried out (here, a gear position on the low speed side that provides the gear ratio K is determined).

、正確な変速モードの判定が可能である。As a result of the judgment, if it is found that the sub-transmission 3 is in the low gear,
In step (108), the gear ratio K is set to 4 main transmission 2.
The gear ratio determined according to the combination of each gear of the automatic sub-transmission 3 is determined from the relationship between the engine rotation speed Ne and the vehicle speed V, and the gear ratio of the main transmission 2 is determined based on the relationship between the engine speed Ne and the vehicle speed V. Since the gear position is determined, even if it cannot be determined from the gear ratio alone, the accurate gear position of the main transmission 2 can be determined based on the gear position of the auxiliary transmission 3. There is no need to provide a switch for detecting the shift position, and the data such as the vehicle speed V and the engine rotation speed Ne are indispensable data for the control circuit 8 that automatically shifts the sub-transmission 3 according to the driving situation of the vehicle. In addition, since the gear position of the sub-transmission 3 is determined by the control circuit 8 itself, it is possible to accurately determine the gear shift mode simply by incorporating a program for determining the gear position in the control circuit 8 itself.

また車速やエンジン回転数といったデータは。As explained above, according to the present invention, the gear ratio determined according to the combination of each gear stage of the manually operated main transmission and the automatic transmission sub-transmission is determined from the relationship between the engine speed and the vehicle speed. Since the gear position of the main transmission is determined in conjunction with the gear position of the auxiliary transmission, even if it cannot be determined from the gear ratio alone, the correct gear position of the main transmission can be determined based on the gear position of the auxiliary transmission. Therefore, there is no need to provide a switch for detecting the shift position on the main transmission.
Also, data such as vehicle speed and engine speed.

ードの判定が可能である等の優れた効果を奏する。This data is indispensable for the control circuit that automatically shifts the sub-transmission depending on the vehicle's driving conditions.Moreover, since the control circuit itself determines the gear position of the sub-transmission, there is no data in the control circuit (for determining the gear position). Just by incorporating this program, you can achieve excellent effects such as being able to accurately determine the shift mode.
