The Delphi-equpped self-driving Audi SQ5 completed its cross country road trip from San Franciso to New York via a southern route through in total autonomous mode for 99% of the trip.

The trip of 3,400 miles ended New York City, New York, allowing Delphi to claim it as America’s first and longest coast-to-coast drive by an autonomous vehicle.

The self-driving car drove through Los Angeles, Phoenix, El Paso, Jackson, Atlanta, Washington D.C. New Jersey to New York. Unlike other coast-to-coast drives by human drivers who may go past the local speed limits, the Audi did not exceed the speed limit.

The team of six engineers collected nearly three terabytes of data which equals about 30% of the texts in the Library of Congress.

On the trip, the car had to deal with difficult situations such as traffic circles, construction zones, bridges, tunnels, aggressive drivers and multiple climates including rain in Texas. The car was monitored by a team of engineers. The car made complex decisions, like stopping and then proceeding at a four-way stop, merging onto the highway or calculating the safest maneuver around a bicyclist on a city street.

Delphi’s self-driving vehicle used collision mitigation, integrated radar and camera systems, forward collision and lane departure warning.

The coast-to-coast drive was used by Delphi engineers to research and collect data for future drives.

So far in the month March, the Delphi’s Audi SQ5 is winning the race for the most media attention, followed Tesla and Mercedes-Benz.

Other self-driving car contenders are Valeo’s Volkswagen, Renault-Nissan, Volvo, and, Google that wants to work with automakers.

Mercedes F015 that made its stage debut as “Luxury in Motion” at CES in January.

The most wanted features of self-driving cars are “self-adjusting performance based on weather conditions,” and “self-parking to find a parking space”.
