VEHICLE REFLECTION IDENTIFICATION

A computer includes a processor and a memory, and the memory stores instructions executable by the processor to determine a value over time derived from a region of sensor data from an optical sensor of a host vehicle; determine that the value over time matches a stored temporal pattern; upon determining that the value over time matches the stored temporal pattern, classify an object at the region as a surface reflecting a signal from an illuminator of an origin vehicle; and actuate a component of the host vehicle based on a classification of the object at the region.
