Description
また、バランス推力とプライマリプーリ11の最大推力との差が大きいほど変速速度の上限値は高く(時定数は小さく)設定されるので、差推力に基づいて実現可能な変速速度を適切に設定することができ、実変速比が目標変速比に追従できなくなることを防止できる。(請求項2に対応)
さらに、変速速度の上限値が高いほど目標変速比は高く設定されるので、実変速比が目標変速比に追従できなくなることを防止できる。(請求項3に対応)
さらに、ライン圧の上限値は油温と油圧ポンプ34の回転速度に基づいて演算されるので、演算精度を向上させることができる。(請求項4に対応)
以上説明した実施形態に限定されることなく、その技術的思想の範囲内において種々の変形や変更が可能である。
