Lane assignment system

A lane assignment system, the system comprising:

• a digital-map, the digital-map indicating a position of a host-vehicle traveling in a travel-lane on a roadway;
• a ranging-sensor, the ranging sensor detecting a lateral-distance to an other-vehicle traveling on the roadway proximate the host-vehicle;
• and
• one or more controller-circuits in communication with the digital-map and the ranging-sensor, the one or more controller-circuits:
• determining a lateral-variation of the lateral-distance;
• determining whether the lateral-variation is greater than a dynamic-threshold;
• determining whether a second-lane exists beyond a first-lane based on the digital-map, the first-lane characterized as being adjacent to the travel-lane;
• in accordance with the determination that the lateral-variation is greater than the dynamic-threshold and that the second-lane exists, determining that the other-vehicle is traveling in the second-lane;
• and
• operating the host-vehicle in accordance with the other-vehicle traveling in the second-lane.

A method of operating a lane assignment system, the method comprising:

• indicating a position of a host-vehicle traveling in a travel-lane on a roadway with a digital-map;
• detecting a lateral-distance to an other-vehicle traveling on the roadway proximate the host-vehicle with a ranging-sensor;
• determining, with one or more controller-circuits in communication with the digital-map and the ranging-sensor, a lateral-variation of the lateral-distance;
• determining whether the lateral-variation is greater than a dynamic-threshold;
• determining whether a second-lane exists beyond a first-lane based on the digital-map, the first-lane characterized as being adjacent to the travel-lane;
• in accordance with the determination that the lateral-variation is greater than the dynamic-threshold and that the second-lane does not exist;
• determining that the other-vehicle is traveling in the first-lane;
• and
• operating the host-vehicle in accordance with the other-vehicle traveling in the first-lane.
