How Cadillac Super Cruise Stays Ahead of the Competition
Owning a fully self-driving car may however be years away, but luxury automakers are giving drivers a taste of what it's like to let democratic tech accept over. Many offer sophisticated lane-centering systems that steer a vehicle, while Cadillac's system lets drivers remove their hands from the wheel for long periods of time.
I've tested most of these systems, including BMW Traffic Jam Aid, Mercedes-Benz Active Steering Assist, and Volvo Pilot Assist II, although I oasis't even so tested Tesla Autopilot with Autosteer. Only apart from Cadillac Super Cruise, they take a long way to go before they're shut to fully self-driving or even comfortable and convenient to utilize.
Lane-centering systems use a combination of cameras to capture lane markings, radar sensors to discover vehicles and objects in the vicinity, and software to ensure the motorcar stays between the stripes and doesn't crash into annihilation. The systems also require drivers to have their easily on the steering wheel or make small steering inputs, otherwise they will turn off after a serial of warnings.
Cadillac is over again the exception. While testing the arrangement last yr, I drove mostly hands-free on a 700-mile trip from Dallas to Santa Atomic number 26, although the organization turns off if you take your eyes off the road for a period of time. Judging other such systems against Cadillac Super Prowl is an apples-to-oranges comparison, however, since the system has a cardinal component other organization lack. Merely perhaps non for long.
Maps every bit Self-Driving Sensor
Cadillac Super Cruise uses Lidar maps from startup Ushr, which mapped every mile of interstate highway in the US and Canada by driving it. That means a Cadillac with Super Cruise will know exactly what it will meet—every curve, exit, and lane merge.
"Our Hard disk map information provides another layer of safety, precisely identifying the drivable and non-drivable areas of the roadway," Brian Radloff, VP of Business organization Development and Sales for Ushr, told me.
During my eleven-hour Super Cruise from Dallas to Santa Fe terminal fall, the non-drivable parts of the road were few and far between, and I only had my easily on the cycle for an hr at the almost the entire time. One instance was westward of Amarillo on a stretch of road nether construction, where lanes had shifted and the striping at that place had been repainted.
In case you're wondering, Ushr and Cadillac monitor road structure in mapped areas, and when roadwork starts, they'll temporarily deactivate Super Prowl for that department of highway. When the work is complete, an over-the-air software update enables it again.
Well before I encountered the lane-shift situation in West Texas, Super Prowl alerted me that information technology would undo via a light bar in the steering wheel that flashes green and then blood-red to indicate that the arrangement was deactivating, and information technology was time to take over steering. The motorcar also issued audible, visual, and tactile alerts by vibrating the seat. If you still don't get the picture, an OnStar operator will telephone call.
This extensive mapping exercise is i reason it took Cadillac five years to bring Super Cruise to production later beginning announcing it in 2022. And it'due south what separates Super Cruise from other systems on the market.
I'm sure rivals volition eventually catch up. "In our talks with OEMs, engineers are telling us information technology would be a fault not to include an HD map equally precise every bit ours in their Level two and above democratic systems," Ushr'south Radloff added. That is, if they always want to compete with Cadillac Super Cruise
