Abstract
An electronic parking pawl actuator which uses a smaller motor and higher gear ratio has the ability to configure a rooster comb to engage with various park detents, and reduces the mechanical and software design complexity. Furthermore, the electronic park actuator limits the amount of back drivable range (unable to perform an external park to neutral shift) for theft deterrence, and also allows operation (speed performance) and a lower motor peak current. The electronic parking pawl actuator includes an electric motor, a drive gear, the drive gear operable for being driven by the electric motor, and a drive mechanism, the drive mechanism is operable for being driven by the drive gear. The drive mechanism is engaged with an output shaft of a gear selector of a transmission, and the drive mechanism is rotatable relative to the drive gear, allowing the output shaft to be located in a desired position.
