Audi has unveiled today a new version of the Autonomous Audi TTS Pikes Peak, the car that can drive itself. The new TTS Pikes Peak will make its first high-speed test runs up Pikes Peak in Colorado this fall.
The Autonomous Audi TTS Pikes Peak is based on a street-ready Audi TTS sports car. An Audi TTS was chosen due to its native systems. The drive-by-wire throttle and a semiautomatic DSG gearbox were a good fit with the electronics that allow the car to drive without human input.
The design of the TTS Pikes Peak was inspired by the rally car themes from the 1980s.
“We were very much inspired by the Pikes Peak race cars,” noted Raul Cenan, Lead Designer on the TTS project. “But there was very different technology used in those cars overall. So we decided to go with more modern elements that were heritage-inspired.“
The hardware added to the TTS is really no different than any laptop computer. The car currently uses two computers in its trunk – one running safety critical algorithms using Oracle’s Real Time Java (Java RTS) and the other running vehicle dynamics algorithms. The two sets of algorithms are what enable the TTS to drive at the limits of handling on a variety of surfaces, speeds and conditions.
The differential GPS system keeps the TTS within two centimeters of its mark on a normal course. Since Pikes Peak is anything, but normal, the research team would like to get that number down to one meter.
The Audi TTS Pikes Peak will also be attempting a Guiness Book of World Record as it makes a land speed attempt at the El Mirage Lake dry-lake bed in southern California or another nearby location in the Fall as well as attempting fastest speed in an autonomous vehicle.
