Abstract

A method for vision assisted parking of a vehicle includes displaying video images derived from image data captured by a camera. A controller is operated in a first mode to generate a first overlay that includes a parking space representation of a parking space where the vehicle may be parked, and that is overlayed on the displayed video images at an offset position and remains at the offset position while the driver maneuvers the vehicle to position the parking space representation at a target parking location. The controller is operated in a second mode to generate a second overlay that includes (i) a representation of a predicted rearward path of travel of the vehicle and (ii) a representation of a determined target path. The second overlay is adjusted responsive to steering of the vehicle while the driver follows the determined target path towards and into the target parking location.

Dependent claims

A method for vision assisted parking of a vehicle, said method comprising:

capturing image data via a camera mounted at the vehicle and having a field of view rearward and sideward of the vehicle;
displaying video images at a display screen in the vehicle, wherein the video images are derived from image data captured by said camera;
operating a controller in a first mode responsive to a first user input, wherein the controller, when operating in the first mode, generates a first overlay that is overlayed on the video images displayed at the display screen;
wherein the first overlay comprises a parking space representation of a parking space where the vehicle may be parked, and wherein the first overlay is overlayed on the video images at an offset position so that the parking space representation appears offset a selected distance behind the vehicle and a selected distance laterally from the vehicle;
the first overlay remaining at the offset position at the display screen while a driver of the vehicle is maneuvering the vehicle to position the parking space representation at a target parking location that is located within the field of view of said camera and that is being displayed at the display screen;
operating the controller in a second mode responsive to a second user input, wherein the controller, when operating in the second mode, generates a second overlay that is overlayed on the video images displayed at the display screen;
predicting a rearward path of travel of the vehicle based on steering of the vehicle;
determining a target path for the vehicle to follow to maneuver the vehicle from its current location into the target parking location;
wherein the second overlay comprises (i) a representation of the predicted rearward path of travel of the vehicle and (ii) a representation of the determined target path;
and
adjusting the second overlay responsive to steering of the vehicle while the driver is reversing the vehicle to generally follow the determined target path towards and into the target parking location.

operating a controller in a first mode responsive to a first user input, wherein the controller, when operating in the first mode, generates a first overlay that is overlayed on the video images displayed at the display screen;
wherein the first overlay comprises a parking space representation of a parking space where the vehicle may be parked, and wherein the first overlay is overlayed on the video images at an offset position so that the parking space representation appears offset a selected distance behind the vehicle and a selected distance laterally from the vehicle, and wherein the parking space representation comprises (i) a rectangular representation that is overlayed on the video images to appear offset the selected distance behind the vehicle and the selected distance laterally from the vehicle and (ii) a linear segment extending forward and rearward from the rectangular representation and along a side of the rectangular representation closest to the vehicle and parallel to the target parking location;
the first overlay remaining at the offset position at the display screen while a driver of the vehicle is maneuvering the vehicle to position the parking space representation at a target parking location that is located within the field of view of said camera and that is being displayed at the display screen;
operating the controller in a second mode responsive to the vehicle shifting into a reverse gear, wherein the controller, when operating in the second mode, generates a second overlay that is overlayed on the video images displayed at the display screen;
predicting a rearward path of travel of the vehicle based on steering of the vehicle;
determining a target path for the vehicle to follow to maneuver the vehicle from its current location into the target parking location;
wherein the second overlay comprises (i) a representation of the predicted rearward path of travel of the vehicle and (ii) a representation of the determined target path;
and
adjusting the second overlay responsive to steering of the vehicle while the driver is reversing the vehicle to generally follow the determined target path towards and into the target parking location.
