Abstract: A parking pawl is implemented on a series type, hybrid electric vehicle by providing a transmission having a moveable locking plate. The locking plate is used to selectively engage and disengage from one of the power transfer gears of the transmission. While the locking plate is linearly moveable between engaged and disengaged position, it is locked against rotation and prevents rotation of the power transfer gear when engaged thereto. An electromagnet is used to pull the locking plate from an engaged position to a retracted, disengaged position. A compression spring biases the plate toward the engaged position with the rotating gear. The locking plate can be held in the retracted position by moveable locking pins to avoid any need to keep the electromagnet energized.
