Advanced user interaction features for remote park assist

A vehicle system comprising:

• a vehicle configured to:
• detect surrounding areas thereof;
• estimate, based on data, a parking space and boundaries of obstacles around the parking space;
• and
• perform an autonomous parking maneuver along a calculated path into the parking space;
• and
• a mobile device comprising a touchscreen, the mobile device configured to:
• display representations of the vehicle and the surrounding areas;
• receive a continuous, uninterrupted user input for the duration of the autonomous parking maneuver on a display showing the representations, the continuous, uninterrupted user input verifying that a user is supervising the vehicle during the autonomous parking maneuver;
• periodically transmit, based on the verification that the user is supervising the vehicle, an activation message to the vehicle, wherein a failure to provide continuous, uninterrupted user input causes an interruption in periodically transmitting the activation message;
• the vehicle, based on periodically receiving the activation message, is further configured to perform the autonomous parking maneuver along the calculated path;
• and
• the vehicle, based on the interruption in periodically receiving the activation message, is further configured to disable the autonomous parking maneuver.
