To provide a parking mechanism which can simplify control for making a parking gear and a claw of a parking pole engaged with each other, and can exactly fix a vehicle thereto.SOLUTION: A parking mechanism of a vehicle using an electric motor 100 as a drive source has a parking gear 102 arranged at a shaft which rotates in conjunction with a rotating shaft 101 of the electric motor, a parking pole 210 for fixing the vehicle by making a claw 211 engaged with a tooth groove of the parking gear, and a control part for controlling operations of the electric motor and the parking pole. The number of teeth of the parking gear is a number proportional to the number of poles of the electric motor, the positions of teeth of the parking gear are arranged so that a center position of a magnet pole arranged at a rotor of the electric motor and a phase coincides with each other, and the control part carries an inter-line current to a stator so that a d-axis of the rotor coincides with a magnetic field of the stator before the actuation of the parking mechanism, thus stopping the parking gear in a position in which the claw of the parking pole and the tooth groove of the parking gear are engaged with each other.SELECTED DRAWING: Figure 3

    【課題】パーキングギヤとパーキングポールの爪とを噛み合わせる制御を簡略化でき、かつ確実な車両固定が可能となるパーキング機構を提供する。【解決手段】電動機100を駆動源とする車両のパーキング機構は、電動機の回転軸101と連動して回転する軸に配置されたパーキングギヤ102と、パーキングギヤの歯溝に爪211を噛み合わせて車両を固定するパーキングポール210と、電動機およびパーキングポールの動作を制御する制御部と、を有し、パーキングギヤの歯数は電動機の極数と比例する数であり、パーキングギヤの歯位置は電動機のロータに配置された磁極の中心位置と位相が一致するように配置され、制御部はパーキング機構の作動前にロータのd軸がステータの磁界に一致するようにステータに線間電流を通電することで、パーキングポールの爪とパーキングギヤの歯溝とが噛み合う位置にパーキングギヤを停止させる。【選択図】図3
