Definitions
- the present invention relates to a control device and a control method for a vehicle and a device, and more particularly to a technique for controlling a device based on values determined for each of a plurality of control modes.
- a continuously variable transmission capable of changing the gear ratio steplessly is known.
- a continuously variable transmission for example, a metal belt or chain is sandwiched between a primary pulley and a secondary pulley.
- the gear ratio is changed by changing the hydraulic pressure supplied to the primary pulley, more specifically, the hydraulic pressure supplied to the primary sheave of the primary pulley.
- the groove width of the primary pulley becomes narrower.
- the effective diameter of the primary pulley is increased.

Abstract
Description
図1を参照して、車両に搭載されたパワートレーン100のエンジン200の出力は、トルクコンバータ300を介して、前後進切換装置400を有する無段変速機500に入力される。無段変速機500の出力は、減速歯車600および差動歯車装置700に伝達され、左右の駆動輪800へ分配される。パワートレーン100は、後述するECU(Electronic Control Unit)900により制御される。なお、エンジン200の代わりにもしくは加えて、モータを駆動源として用いるようにしてもよい。無段変速機500の代わりに多段自動変速機を用いるようにしてもよい。
ステップ(以下、ステップをSと略す)100にて、ECU900は、複数の制御モード毎に、金属ベルト510の挟圧力の第1設定値を設定する。
S106にて、ECU900は、金属ベルト510の挟圧力が目標値になるように、無段変速機500を制御する。
[第2の実施の形態]
以下、第2の実施の形態について説明する。上述したように、第1の実施の形態においては、実際の挟圧力のアンダーシュートを防止するために、複数の制御モード毎に設定された第1設定値から、第1設定値に比べて遅れて変化する第2設定値が算出される。一方、図10に示すように、第1設定値の和が一定である間は、目標値に対して実際の挟圧力がアンダーシュート等し得ない。したがって、低下する前後の第1設定値を滑らかに繋ぐための処理、すなわち第2設定値の算出は必要ない。そこで、本実施の形態においては、第2設定値が無効にされる。第2設定値の無効化は、複数の制御モードにおいて設定された複数の第1設定値の和が一定である間、複数の第1設定値の和以下に目標値が制限されることによって達成される。
このようにすれば、挟圧力の無駄な増大を防ぐことができる。
