図１はディーゼル動車用変速機の構造と、本考案の速度段切換え制御装置の一 実施例を示したものであるが、変速機の構造は従来と同じことから、この図を引 用して従来の変速機の制御方法を説明する。 FIG. 1 shows the structure of a diesel vehicle transmission and an embodiment of the speed change control device of the present invention. Since the structure of the transmission is the same as the conventional one, this figure is used as a reference. A conventional transmission control method will be described.
【０００３】 車両を発進させるときは、まず機関１をアイドリング状態とし、車両の進行方 向に合わせて正転クラッチ１３または逆転クラッチ１４のいずれか一方を嵌合し てから変速クラッチ４を嵌合すると共に、機関の出力を上昇させていくと、機関 出力は入力軸６からトルクコンバータ５とフリーホイール１０を経て、変速軸９ と一体の変速歯車２３へ伝達され、正転クラッチ１３または逆転クラッチ１４を 介して出力軸１７に変速運転の回転速度が伝達される。When the vehicle is started, first, the engine 1 is set in an idling state, and either the forward rotation clutch 13 or the reverse rotation clutch 14 is engaged according to the traveling direction of the vehicle, and then the speed change clutch 4 is engaged. As the engine output is increased, the engine output is transmitted from the input shaft 6 through the torque converter 5 and the freewheel 10 to the speed change gear 23 integrated with the speed change shaft 9, and the forward rotation clutch 13 or the reverse rotation clutch 13 is transmitted. The rotational speed of the shifting operation is transmitted to the output shaft 17 via 14.
【０００４】 次いで、この変速運転のもとで車速が所定値に達し、その検出信号をコントロ ーラが受けると、機関にアイドリング指令を出すと共に変速クラッチ４を解放し 、１速段クラッチ１１の入力側と出力側の回転速度の同期を取るべく、機関の回 転速度をコントローラにより調整した後、１速段クラッチ１１を嵌合し、再び機 関出力をアップすると、機関出力は入力軸６から１速駆動歯車１９、１速被動歯 車１８、１速段クラッチ１１、１速出力歯車２２、変速歯車２３を経て、同様に して、出力軸１７に直結１速の回転速度が伝達される。Next, when the vehicle speed reaches a predetermined value under this speed change operation and the detection signal is received by the controller, an idling command is issued to the engine and the speed change clutch 4 is disengaged. When the engine speed is adjusted by the controller in order to synchronize the rotational speeds of the input side and the output side, the first speed clutch 11 is engaged, and the engine output is increased again. Through the first speed drive gear 19, the first speed driven gear 18, the first speed clutch 11, the first speed output gear 22, and the speed change gear 23, and in the same manner, the directly connected first speed is transmitted to the output shaft 17. It
【０００５】 更に、この直結１速運転のもとで車速が所定値に達し、その検出信号をコント ローラが受けると、機関をアイドリングにすると共に１速段クラッチ１１を解放 し、２速段クラッチ１２の入力側と出力側の回転速度の同期を取るべく、機関１ の回転速度を調整して２速段クラッチ１２を嵌合した後、機関の出力をアップし て変速運転の場合と同様にして、出力軸１７に直結２速の回転速度を伝達するも のである。（特開平３−３６３号公報参照）Further, when the vehicle speed reaches a predetermined value under the direct connection first speed operation and the controller receives the detection signal, the engine is idling and the first speed clutch 11 is disengaged, and the second speed clutch is released. In order to synchronize the rotational speeds of the input side and the output side of 12, the rotational speed of the engine 1 is adjusted and the second speed clutch 12 is engaged, and then the output of the engine is increased to perform the same operation as in the gear shifting operation. Thus, the rotation speed of the second speed directly coupled is transmitted to the output shaft 17. (See JP-A-3-363)

従来の切換制御方法では、クラッチ切換え時、結合すべきクラッチの同期を取 る間、一時的に変速機の動力伝達系が遮断されて出力トルクが０となる。このた め、加速途上で切換えると、減速ショックが発生し、また、上り勾配などで走行 抵抗が大きくなると、出力トルクが０の間に車速が低下してきて頻繁に速度段の 切換えが行われるようになり、切換えハンチングを引き起こす場合がある。その 結果、加速が滑らかに行われなくなって最高車速到達時間が長くなり、走行性能 が低下するという問題を有していた。本考案は上記問題点に鑑みてなされたもの で、速度段切換え時におけるトルク伝達の中断をなくす、切換制御装置を提供す ることを目的とする。 In the conventional shift control method, when the clutches are switched, while the clutches to be engaged are synchronized, the power transmission system of the transmission is temporarily cut off and the output torque becomes zero. For this reason, when switching during acceleration, a deceleration shock occurs, and when running resistance increases due to an upslope, etc., the vehicle speed decreases while the output torque is 0, and the speed stages are frequently switched. And may cause switching hunting. As a result, there was a problem that the acceleration was not performed smoothly and the maximum vehicle speed reached time became longer, and the running performance deteriorated. The present invention has been made in view of the above problems, and an object of the present invention is to provide a switching control device that eliminates interruption of torque transmission during speed stage switching.

変速運転から直結１速運転へ切換わる際に、一時的に、変速クラッチと１速段 クラッチの両者が嵌入されることから、トルクコンバータを経由した、２速段の かみ合い歯数比による変速機の出力回転速度に一致するまで１速段クラッチの入 力側回転速度、即ち、機関回転速度が引き下げられて１速段クラッチが同期し、 嵌合される。その後、機関回転速度を上昇させることによって、変速軸の回転速 度は変速運転時より直結１速運転時の方が大となり、トルクコンバータを介して 伝達されていたトルクはフリーホイールによって遮断され、直結１速運転に移行 される。また、直結１速運転から直結２速運転に切換わる際も前記と同様に、一 時的に変速クラッチが並列して嵌合されるので、トルク伝達が遮断されることな く、直結１速運転から直結２速運転に移行される。 Both the speed change clutch and the first speed clutch are temporarily engaged when switching from the speed change operation to the direct connection first speed operation. Therefore, the transmission using the meshing gear ratio of the second speed via the torque converter. The input side rotational speed of the first speed clutch, that is, the engine rotational speed is reduced until the output rotational speed of 1 is reached, and the first speed clutch is synchronized and engaged. After that, by increasing the engine rotation speed, the rotation speed of the speed change shaft becomes higher in the direct connection first speed operation than in the speed change operation, and the torque transmitted through the torque converter is blocked by the freewheel. Directly connected to 1st speed operation. Also, when switching from the direct-coupling first speed operation to the direct-coupling second speed operation, similarly to the above, the speed change clutches are temporarily fitted in parallel, so that the torque transmission is not interrupted and the direct-coupling first speed operation is not interrupted. The operation shifts from direct operation to second gear operation.

In the state in which the ON signal is output to the first speed clutch switching solenoid valve and the first speed clutch is engaged. reaches the switching speed of the direct second speed at t 3, oN signal is output to the shift clutch switching solenoid valve receives a clutch Hamagoken knowledge signal from the shifting clutch engagement detector in t 4, 1 speed An OFF signal is output to the clutch switching solenoid valve to release the 1st speed clutch, and the delay relay operates to output an ON signal to the 2nd speed clutch switching solenoid valve at t 5 , and the 2nd speed clutch is engaged at t 6. When a clutch engagement detection signal from the engagement detector is received, an OFF signal is output to the shift clutch switching solenoid valve to release the shift clutch. Since the shift clutch is engaged between t 3 and t 6 in the transitional transition period, there is no interruption of torque transmission.

この考案によれば、速度段の切換えに際して、運転中の速度段クラッチを直ち に解放せず、一時的に、変速クラッチを同時嵌合して並列的にトルク伝達を行い ながら所要の速度段に切換わるよう制御されるので、切換え時におけるトルク伝 達の中断がなくなり、減速ショックの発生が防止されて乗り心地が改善されると 共に、上り勾配などでも加速が滑らかに行われ、走行性能が向上する。 According to this invention, when the speed stage is switched, the speed stage clutch during operation is not immediately released, but the speed change clutch is temporarily engaged at the same time to transmit the torque in parallel while the required speed stage is being transmitted. Since it is controlled so that the torque transmission is not interrupted at the time of switching, deceleration shock is prevented from occurring and riding comfort is improved, and acceleration is performed smoothly even on uphill grades, etc. Is improved.
