Abstract
Systems and methods for assisting drivers to maneuver a vehicle include a plurality of image sensors about a vehicle capture image data. At least one processor is programmed to display one or more types of overhead views on a vehicle display based on the image data. For example, an environment-fixed overhead composite image can be displayed on the vehicle display. In the environment-fixed overhead composite image, an environment about the vehicle is displayed spatially fixed as the vehicle is maneuvered, and a graphical image representing the vehicle moves within the environment-fixed overhead composite image as the vehicle maneuvered. This type of overhead view can be shown when, for example, distance between the vehicle and a target object is below a threshold.
Claims15
A system for assisting a driver to maneuver a vehicle, the system comprising:
- a plurality of image sensors configured to mount at various locations about a vehicle, wherein at least some of the image sensors are cameras, and wherein the image sensors are configured to output image data;
- a vehicle display;
- and
- at least one processor programmed to:
- receive image data from the cameras,
- utilize a first of the image sensors to determine a distance between the first of the image sensors and a target object external to the vehicle,
- generate an environment-fixed overhead composite image on the vehicle display representing a first overhead view of an environment about the vehicle wherein the environment displayed on the vehicle display is spatially fixed as the vehicle is maneuvered and a graphical image representing the vehicle is configured to move within the environment-fixed overhead composite image as the vehicle maneuvered,
- generate a vehicle-fixed overhead composite image on the vehicle display representing a second overhead view of the environment about the vehicle wherein the environment displayed on the vehicle display is spatially moveable as the vehicle is maneuvered and the graphical image representing the vehicle is fixed within the vehicle-fixed overhead composite image as the vehicle is maneuvered,
- determine a size and orientation of a fixed display field of view of the environment-fixed overhead composite image based on the distance, wherein the size of the fixed display field of view remains fixed as the vehicle is maneuvered, and
- switch the vehicle display between displaying the vehicle-fixed overhead composite image and the environment-fixed overhead composite image based on the distance.
A system for assisting a driver to maneuver a vehicle, the system comprising:
- a plurality of image sensors configured to mount at various locations about a vehicle, wherein at least some of the image sensors are cameras, and wherein the image sensors are configured to output image data;
- a vehicle display;
- and
- at least one processor programmed to:
- receive image data from the cameras,
- utilize a first of the image sensors to determine a distance between the first of the image sensors and a target object external to the vehicle, and
- in response to the distance being less than a threshold, utilize the image data to generate an environment-fixed overhead composite image on the vehicle display representing an overhead view of an environment about the vehicle, determine a size and orientation of a fixed display field of view of the environment-fixed overhead composite image based on the distance, wherein the size of the fixed display field of view remains fixed as the vehicle is maneuvered, wherein the environment displayed within the environment-fixed overhead composite image is spatially fixed as the vehicle is maneuvered and a graphical image representing the vehicle is configured to move within the environment-fixed overhead composite image as the vehicle maneuvered.
A method of assisting a driver to maneuver a vehicle, the method comprising:
- receiving image data from a plurality of image sensors mounted about a vehicle, wherein at least some of the image sensors are cameras;
- and
- determining a distance between one of the image sensors and a target object external to the vehicle;
- based on the image data, and in response to the distance reducing below a threshold, generating an environment-fixed overhead composite image on a vehicle display representing an overhead view of an environment about the vehicle, wherein within the environment-fixed overhead composite image the environment is spatially fixed as the vehicle is maneuvered and a graphical image representing the vehicle is configured to move within the environment-fixed overhead composite image as the vehicle maneuvered;
- and
- determine a size and orientation of a fixed display field of view of the environment-fixed overhead composite image based on the distance and a location of the object, wherein the size of the fixed display field of view remains fixed as the vehicle is maneuvered.
