Since CES, the software underpinning Aptiv’s self-driving system has evolved. Then, software developed by Ottomatika, a Carnegie Mellon University spinoff purchased by Aptiv in 2015, controlled perception and vehicle movement. In the intervening months, engineers have integrated software from NuTonomy, the self-driving software startup Aptiv acquired in 2017 for $450 million.

Further, Aptiv has enhanced its mapping of the city. During the CES demos, vehicle systems controlled their own movements along public roads, but human safety drivers retook control in parking lots of the casinos and other destinations. An Aptiv spokesperson told C/D that the newly launched program will offer autonomous service all the way to pickup and drop-off spots in parking lots, which suggests the company has now mapped the applicable parking lots.
