A vehicular vision system includes a camera disposed at a vehicle and viewing rear of the vehicle, and an electronic control unit (ECU) having an image processor for processing image data captured by the camera. The vehicular vision system, responsive to processing by the image processor of image data captured by the camera, determines an individual has moved within a threshold distance of the rear of the vehicle. The vehicular vision system, responsive to determining that the individual has moved within the threshold distance of the vehicle, determines whether the individual is an authorized user of the vehicle. Responsive to at least to determining that the individual is an authorized user of the vehicle, a powered rear lift gate mechanism of the vehicle opens a rear lift gate of the vehicle to allow the user access to the interior of the vehicle.

A system for granting access to an autonomous vehicle comprises the autonomous vehicle, a control device, and a communication device associated with the autonomous vehicle. The communication device receives a signal from a device associated with a user that indicates the user requests the autonomous vehicle to pull over. The control device pulls the autonomous vehicle over to a side of road traveled by the autonomous vehicle. The control device receives a credential associated with the user. The control device determines whether the credential is verified. In response to determining that the credential is verified, the control device grants the user to access the autonomous vehicle.

An authentication method includes: receiving, from a terminal of a user, a user ID for identifying the user and a target vehicle ID for identifying a target vehicle that the user tries to authenticate; determining whether the target vehicle ID matches a reserved vehicle ID for identifying a reserved vehicle whose dispatch has been reserved by the user; in a case where the target vehicle ID matches the reserved vehicle ID, transmitting, to the target vehicle, an unlocking instruction to unlock a door of the target vehicle and causing the terminal to present a message indicating that the user is allowed to get on the target vehicle; and in a case where the target vehicle ID does not match the reserved vehicle ID, causing the terminal to present a message indicating that the target vehicle is not the reserved vehicle of the user.

System, methods, and other embodiments described herein relate to adapting vehicle access by detecting a person carrying an object. In one embodiment, a method includes detecting a person near a vehicle for gaining access. The method also includes scanning the person for an object using a radar of the vehicle, wherein information from the radar indicates densities of the person and the object. Upon detecting the object using the densities, the method also includes adapting the access to a compartment of the vehicle.
