Abstract
A locking system for an electric propulsion system is disclosed. The system includes a propulsor configured to propel an electric vehicle and a motor operatively connected to the propulsor configured to power the propulsor. The motor includes a rotor connected to the propulsor and a stator configured to rotate the rotor. A propulsor sensor is configured to determine a motion parameter of the propulsor. A lock is configured to prevent a movement of the propulsor. A controller is configured to receive a signal from the propulsor sensor and control the motor as a function of the signal from the propulsor sensor, wherein controlling the motor includes allowing the propulsor to slow at a desired rate for parking.
