Beschreibung
Zusammenfassung:	A computer includes a processor and a memory, and the memory stores instructions executable to receive range data from a plurality of ultrasonic sensors on a vehicle, determine two ellipses from respective pulses of the range datadetermine a plurality of intersections of the two ellipses, exclude a subset of the intersections, and actuate a component of the vehicle based on the nonexcluded intersections. The ultrasonic sensors have respective fields of view, the fields of view overlap, and the range data includes distances traveled by pulses emitted by the ultrasonic sensors and received by the ultrasonic sensors. Each pulse is emitted by a different one of the ultrasonic sensors than received that pulse. Excluding the subset of the intersections is based on the fields of view.
