Abstract
【解決手段】目標入力回転設定手段82により過渡目標入力軸回転速度NIN * Pが、加速要求が有る場合にはステップ状に増加させた第1過渡目標入力軸回転速度NIN * P1に保持され、その後第1過渡目標入力軸回転速度NIN * P1よりも低い実入力回転速度NIN近傍から第1過渡目標入力軸回転速度NIN * P1に向かって漸増させた第2過渡目標入力軸回転速度NIN * P2に設定される一方で、急加速要求が有る場合には第1過渡目標入力軸回転速度NIN * P1に保持されて第2過渡目標入力軸回転速度NIN * P2に設定されないので、加速要求時と急加速要求時とで過渡目標入力軸回転速度NIN * Pの設定が切り換えられることにより、運転者の加速要求に応じた加速感を実現することができる。
