General Motors intends to introduce a new automated driving system called “Ultra Cruise” in the first premium vehicles in the course of 2023, which should be able to take over 95 percent of all situations, including turning and parking. The manufacturer relies on an armada of sensors and powerful 5 nm processors.

The Level 3 assistance system already available from premium brands such as Cadillac is called “Super Cruise” and allows automated driving on highways approved by the company in the USA and Canada. As of July 2021, this included more than 320,000 kilometers of compatible roads in North America. Super Cruise allows the driver to permanently take their hands off the steering wheel and hand over all driving tasks to the car. The traffic situation still has to be monitored and the driver has to be ready to take over within a certain period of time.

Ultra cruise for millions of kilometers of road

The further development presented by General Motors is called “Ultra Cruise” and is intended to enable automated driving in 95 percent of all situations and therefore no longer just on highways. At the start in the USA and Canada, GM wants to release more than 3.2 million kilometers of roads for the system; in the long term, more than 5.4 million kilometers are targeted. In addition to the already approved highways, use on paved country roads, roads in cities and within residential areas is planned.

These are the new supported features

Ultra Cruise will build on the capabilities of Super Cruise, which GM will continue to offer and which GM intends to introduce in the mainstream segment of the various group brands in the future, after it was only available from the premium brand Cadillac at the start. Ultra Cruise will offer the following features beyond the capabilities of Super Cruise, with GM planning continuous improvements through OTA updates.

  • A new dynamic display with feedback from the system
  • Responds to permanent signs, traffic lights and other traffic signs
  • Follows routes of the internal navigation system
  • Completely takes over the forward drive after the speed limit
  • Supports automatic and on-demand lane changes
  • Supports turning left and right
  • Can avoid obstacles
  • Can park in driveways in residential areas

In situations that Ultra Cruise cannot master without manual intervention, the system starts a data recording in order to analyze this information in GM’s backend and use it for future system improvements.

Ultra Cruise uses 5 nm architecture

Ultra Cruise runs on a high-performance 5 nm architecture, as GM explains, but without giving details about the individual chips or suppliers. The system is connected to the recently introduced Ultifi software platform, which GM intends to use in the future to process all cloud-based services, OTA updates, apps, upgrades (functions on demand) and personalized settings.

When it comes to sensors, Ultra Cruise relies on a combination of cameras, radar and lidar (also behind the windshield) to create a 360-degree image of the surroundings. GM also relies on redundant components in critical areas.

The new cockpit visualizes what the car sees

An important part of Ultra is also the new dynamic display that builds on the display for Super Cruise. This is intended to visually convey to the driver that the car and driver see the same thing and, in certain situations, indicate that manual takeover is necessary. The attention camera already known from Super Cruise will be adopted for Ultra Cruise, so that the traffic situation must continue to be monitored.

Ultra Cruise is slated to be rolled out first on Cadillac’s first select models in 2023.
