アクセルペダルにより制御される自動車の内燃機関を備えたパワートレインに設けられている変速機の、変速機入力軸と変速機出力軸との間に配置されている２つのギア間におけるシフトプロセスを、目下係合しているギアと、新たに係合させられるギアとの間のシフト経路に沿って、同期装置の同期閾値を克服しつつ、変速機アクチュエータによって、予め設定される同期力により移動させられるシフトエレメントを介して制御する方法であって、
前記同期力を、前記変速機入力軸と、前記変速機出力軸との間の回転数差勾配の、目標値からの偏差に基づいて調節することを特徴とする、シフトプロセスを制御する方法。 A shift process between two gears disposed between a transmission input shaft and a transmission output shaft of a transmission provided in a power train including an internal combustion engine of an automobile controlled by an accelerator pedal, It is moved along with the preset synchronization force by the transmission actuator along the shift path between the currently engaged gear and the newly engaged gear while overcoming the synchronization threshold of the synchronizer. Controlled via a shift element, comprising:
A method for controlling a shift process, characterized in that the synchronization force is adjusted based on a deviation from a target value of a rotational speed difference gradient between the transmission input shaft and the transmission output shaft. 前記目標値を、アクセルペダルのアクセルペダル値と、新たに係合させられるギアの目標回転数及び目下の回転数から、ギア間の変速比の差を考慮して算出された一方の変速機軸の回転数差と、に少なくとも基づいて算出することを特徴とする、請求項１記載の方法。   The target value is calculated from the accelerator pedal value of the accelerator pedal, the target rotational speed of the newly engaged gear, and the current rotational speed in consideration of the gear ratio difference between the gears. The method according to claim 1, wherein the calculation is based on at least the difference in rotation speed. 前記目標値を、前記自動車の現在調節されているドライブモードに基づいて算出することを特徴とする、請求項２記載の方法。   The method according to claim 2, wherein the target value is calculated based on a currently adjusted drive mode of the vehicle. 前記回転数差勾配を前記シフトプロセス中に、継続して更新することを特徴とする、請求項１から３までのいずれか１項記載の方法。   The method according to claim 1, wherein the speed difference gradient is continuously updated during the shift process. 前記回転数差を、シフトプロセスの同期段階の開始時に算出することを特徴とする、請求項２記載の方法。 Wherein the rotational speed difference, and calculates the time synchronization stage of the start of the shift process, according to claim 2 Symbol placement methods.
