Abstract
An advanced driver assistance system (ADAS) controls a vehicle using two or more of: static objects, a vehicle heading angle, or a vehicle curvature at least when a satellite navigation signal is weak or lost. Distances from the vehicle to the static objects are measured by sensor(s) to be the same in both coordinate systems, and the vehicle location is found as an intersection between circles in the ground coordinate system. The ADAS can use sums of transverse and longitudinal distances, with a vehicle heading angle or a vehicle curvature, to determine the vehicle location with a weak or lost satellite signal, such as using a linear vehicle model or a curvature-based vehicle model.
