Driver assistance system for vehicle
First Claim
1. A method for providing backup assistance for a driver of a vehicle, said method comprising:
- providing a rear backup camera at a vehicle so as to have a field of view at least rearward of the vehicle;
providing a processor at the vehicle;
storing a plurality of sets of overlays in memory, wherein each set of the stored plurality of sets of overlays is associated with a respective vehicle wheelbase configuration of a plurality of different vehicle wheelbase configurations;
providing a wheelbase configuration input to the processor that is representative of the vehicle wheelbase configuration of the vehicle;
selecting, via the processor, and responsive at least in part to the wheelbase configuration input, a particular set of stored overlays from the stored plurality of sets of overlays, wherein the selected set of stored overlays comprises a plurality of individual predicted vehicle trajectory overlays that correspond to respective steering angle ranges for the vehicle wheelbase configuration of the vehicle; and
selecting, via the processor, and responsive at least in part to a steering angle of the vehicle during a reversing maneuver of the vehicle, an individual predicted vehicle trajectory overlay of the selected set of stored overlays for displaying at a display of the vehicle for viewing by a driver of the vehicle during the reversing maneuver of the vehicle.

Abstract
A method for providing backup assistance includes providing a rear backup camera and a processor at a vehicle, and storing a plurality of sets of overlays in memory, with each set of the stored plurality of sets of overlays associated with a respective vehicle wheelbase configuration. A wheelbase configuration input is provided that is representative of the vehicle wheelbase configuration of the vehicle. Responsive at least in part to the input, a particular set of overlays from the stored sets of overlays is selected, with the selected set including a plurality of individual predicted vehicle trajectory overlays that correspond to respective steering angle ranges for the vehicle wheelbase configuration of the vehicle. Responsive at least in part to a steering angle of the vehicle during a reversing maneuver of the vehicle, an individual predicted vehicle trajectory overlay is selected for displaying for viewing by the vehicle driver.
