The system searches for parking spaces/slots/garages. The search may be initiated by the driver. The system should inform the driver that it has identified one or more possible parking spaces/slots/ garages. The system may also be activated after the driver parks the car straight (e.g. 1 m) in front of the garage/ perpendicular parking slot/space. If multiple possible parking spaces/slots/garages are identified, the system should present candidates. The system proposes a parking space/slot/garage, but the driver shall be able to choose the intended parking space/slot/garage from the candidates. The proposed parking space/slot/garage may be used if the driver does not make a selection. The driver transfers the control method to the remote supervision device while the vehicle is stopped. The remote driver then activates the parking manoeuvre using the remote supervision device. Only while the remote driver is using the remote supervision device to continuously give authorization for the vehicle to move, shall the system automatically operate and park the vehicle in the target parking space/ slot/ garage within the specified location accuracy limits. The vehicle is stopped when the final parking position is reached or when the remote driver deactivates the system using the remote supervision device.The system shall start the leaving manoeuvre when it receives and confirms a leaving manoeuvre request from the remote driver. Only while the remote driver is using the remote supervision device to continuously give authorization for the vehicle to move, shall the system automatically operate and move the vehicle from the parking space/slot/garage within the specified location accuracy limits. The vehicle is stopped when the specified position is reached or when the remote driver deactivates the system using the remote supervision device.PAPS shall abort the automated parking/leaving manoeuvres if there is a system failure detected by the PAPS.  The system shall cancel automated control and provide information to the driver upon detecting malfunctions.
