Description
図1は、本発明の一実施形態に係る車両駆動系の全体構成を概略的に示している。
ATCU10には、車両の運転状態を示す各種の検出信号として、車速VSPを検出する車速センサ11からの信号、変速機TMの油温TOILを検出する油温センサ12からの信号、パークモジュール32の駆動部材(パークロッド323)の位置を検出するパーキング位置センサ13、車両が位置する道路の勾配を検出する道路勾配センサ14等からの信号が入力される。本実施形態において、パーキング位置センサ13は、ストロークセンサである。
図2および3は、本実施形態に係る車両駆動系に備わるパークモジュール32の動作を模式的に示しており、図2は、パークモジュール32のパークロック時の状態(パークロック状態)を、図3は、パークモジュール32のパークアンロック時の状態(パークアンロック状態)を、夫々示している。パークモジュール32は、自動変速機の「パークロック装置」を構成する。
本実施形態では、先に述べたパークロック装置32の基本的な制御に加え、ATCU10を構成するCPUにリセット(以下「CPUリセット」という)が生じた場合に、その後の復帰に際して以下のリセット復帰制御を実行する。
本実施形態に係るパークロック装置32および自動変速機の制御装置(ATCU10)は、以上のように構成され、以下、本実施形態により得られる効果をまとめる。
