Among the updates, Audi's autonomous test vehicles will now drive more like humans regularly do - for example, the latest piloted driving software now more clearly signals its intentions when changing lanes by activating the indicators and moving to the edge of the lane before attempting the manoeuvre.
When overtaking trucks and other large vehicles, Audi's self-driving cars will give the truck a much larger lateral gap than smaller vehicles. Also, when other cars want merge into its lane, self-driving Audis can, if necessary, speed up or slow down.
The satellite navigation system is now also able to compute a route that maximises time spent in self-driving mode.
CarAdvice saw an earlier version of Audi's self-driving car at CES 2015, which was able to drive itself most of the way from Silicon Valley, California, to Las Vegas, Nevada. At the 2015 show, we interviewed Daniel Lipinski, project leader for Audi’s automated driving projects.
During our wide-ranging interview, Lipinski talked about some of the ways his team has engineered Audi's self-driving cars to feel more natural to those inside the car.
Overnight, Audi also announced that it is working together with the government of its home town, Ingolstadt, to develop and install infrastructure designed to help self-driving vehicles. Items that will be installed by the city include sensors at intersections.
The company is also collaborating with the government to upgrade sections of the A9 autobahn to include new roadside posts that can be detected further away and new signs that allow vehicles to even more precisely determine their location within a lane.
