Abstract
Description
駆動源の回転トルクを複数の走行段の変速比で変速して、車輪側へ出力する自動変速機を備えた車両において、所定の車速を維持して車両を走行させるオートクルーズ走行の制御を実行する車両用の制御装置であって、
前記オートクルーズ走行の制御が実行中であり、かつ、車両を加速させる制御が実行中でなく、かつ、車速が増加する場合、現在の走行段からシフトダウンした場合の走行段であって、現在の車速が減少するような減速走行段を算出する算出部を備える。
上記制御装置を備える。
図1は、本開示の一実施の形態に係る車両用の制御装置1の機能ブロック図である。本実施の形態に係る制御装置1は、所定の車速を維持して車両を走行させるオートクルーズ走行の制御を実行する。
算出部42は、内燃機関5のフリクション出力特性マップから、1つ下の走行段における内燃機関5の回転数に基づく摩擦抵抗力を求める。また、算出部42は、補助ブレーキ特性マップから、1つ下の走行段における内燃機関5の回転数に基づく補助ブレーキの制動力を求め、それらを合算することで、1つ下の走行段における内燃機関5の制動トルク(車両を減速させるトルク)を求める。
