Abstract

Methods, systems, and devices for an automated ingress and egress system. The system may include a rear back door of a vehicle. The system may further include a seat and a frame coupled to the seat and a floor of the vehicle. The frame may move the seat from inside a cabin of the vehicle to outside the cabin through the rear back door. The system may further include an electronic control unit (ECU) electrically connected to the rear back door and the frame. The ECU may control the rear back door to open the rear back door, control the frame to move the seat from inside the cabin to outside the cabin through the rear back door, control the frame to move the seat from outside the cabin to inside the cabin through the rear back door, and control the rear back door to close the rear back door.
