Abstract
A first distance d1 between a vehicle at a first location and an object is determined. A best fit line representing the object is determined from a plurality of sensor data. A distance Δd to move to a second location is specified. A predicted second distance dp between the vehicle at the second location and the object is determined based on the first distance d1, the distance Δd, and the best fit line. The vehicle is operated from the first location to the second location based on a center steering wheel angle. A measured second distance d2 between the vehicle at the second location and object is determined. Then the center steering wheel angle is one of (a) maintained based on the predicted second distance dp matching the measured second distance d2, or (b) updated based on the predicted second distance dp being different than the measured second distance d2.
