CONTROL DEVICE OF AUTOMATIC TRANSMISSION

To provide a control device of an automatic transmission capable of reducing driver's discomfort feeling in linear upshift after switching a power transmission path.SOLUTION: In a control device of an automatic transmission including a first power transmission path for transmitting power of an engine to wheels through a continuously variable transmission and a second power transmission path for transmitting the power of the engine to the wheels through a gear device, which are arranged in parallel, and selectively using the first power transmission path and the second power transmission path, switching control to switch from the second power transmission path to the first power transmission path is executed under a condition that an input rotating speed is a prescribed rotating speed, and the prescribed rotating speed during the linear shift control is a linear upshift determination rotating speed in selecting the first power transmission path.SELECTED DRAWING: Figure 3 【課題】動力伝達経路を切り替えた後のリニアアップシフトでのドライバーの違和感を低減させることができる自動変速機の制御装置を提供すること。【解決手段】エンジンの動力を無段変速機を介して車輪へ伝達する第１動力伝達経路と、エンジンの動力を歯車装置を介して車輪へ伝達する第２動力伝達経路とを並列に備え、第１動力伝達経路と第２動力伝達経路とが択一的に用いられる自動変速機の制御装置であって、入力回転数が所定回転数であることを条件に、第２動力伝達経路から第１動力伝達経路へ切り替え制御を実行し、リニアシフト制御中の前記所定回転数は、第１動力伝達経路選択時のリニアアップシフト判断回転数とする。【選択図】図３
