The invention relates to a detection device for a crankshaft angle of a hybrid vehicle, which can accurately detect the crankshaft angle even if a driving mode is switched when the crankshaft angle isdetected by a rotary transformer. A controller that calculates a crankshaft angle of an engine on the basis of a signal output from a resolver accumulates the signal and calculates the crankshaft angle on the basis of an accumulated value obtained by accumulation, and holds the crankshaft angle calculated in the first mode when a determination is made that a switch from the first mode to the second mode is established (step S61). A crankshaft angle calculated by integrating the signals in a state of switching to the second mode is added to the held crankshaft angle (step S64) to calculate thecrankshaft angle.

    本发明涉及混合动力车辆的曲轴角的检测装置,在利用旋转变压器来检测曲轴角时即使存在行驶模式的切换也能够准确地检测曲轴角。基于旋转变压器输出的信号来算出发动机的曲轴角的控制器对信号进行累计并且基于累计得到的累计值来算出曲轴角,在从第1模式向第2模式切换的判断成立的情况下,保持在第1模式下算出的曲轴角(步骤S61),将通过在切换为了第2模式的状态下对信号进行累计而算出的曲轴角与保持的曲轴角相加(步骤S64)来算出曲轴角。
