Aptiv reveals details of its autonomous driving sensor fusion

Aptiv's Automated Driving Platform

Aptiv has been supplying ADAS and instrumental in bringing ABS, ESC and lane keeping assist to market. These technologies are the building blocks for more advanced, fully autonomous driving.

With those the building blocks in place, the other requirements for self-driving vehicles will go something like this.

Digital Sensorium
People perceive data through their eyes, ears, smell, touch and taste. For a vehicle to drive itself, it must have this highly developed sensing ability, mimicking these same human functions. Inputs from cameras, radars, LiDARs and a kind of “digital ESP,” what Aptiv calls vehicle-to-everything or V2E, all have to be processed by a very advanced computing platform, which acts as the brain.

  • Aptiv’s 360° radar technology is well known in the industry, having been awarded an Automotive News PACE award.
  • LiDAR, which uses pulsed lasers to accurately measure distances quickly, will also be used by vehicles to monitor other vehicles, pedestrians, and the driving environment.
  • V2X uses radio signals for the vehicle to “talk” to other vehicles and other objects in the environment. The advantage of V2X is the technology can give information to the vehicle that radar and LiDAR can’t “see,” like what’s happening with a stopped vehicle a quarter mile down the highway. V2X does not require line-of-sight.

All of these perception systems allow the vehicle to have the necessary data to safely drive the car, but as with human drivers, the hardest part isn’t the seeing, it’s the thinking and doing that gets us from Point A to Point B safely.

Brains: Making Sense of the Data
In addition to needing proactive vehicle control and good “eyesight” to see the road ahead, software and the hardware are necessary make sense of it all. The software interprets the data, plans the path or route, and sends control inputs to the vehicle at extraordinarily high levels of speed to maneuver safely in its environment.

The autonomous driving platform Aptiv is developing with partner Mobileye, has the capability of a Formula 1 driver, but in this case, it’s not about driving at high speeds. It’s about highly evolved decision-making and control-computing platform.

Getting from Here to There
Aptiv has years of experience in developing active safety systems, including the recent launch of the industry’s first centralized computing platform with Audi zFAS system. These Level 3 and 4 automated driving applications are the basis for building fully autonomous Level 5 vehicles. Using Ottomatika and nuTonomy algorithm platforms, the foundation of the Aptiv autonomous driving platform, provide capability in drive perception, planning, and motion control for fully autonomous solutions.

The ultimate objective is safer, more efficient, more convenient mobility. Aptiv’s capabilities demonstrate it is possible to not only replicate the perceiving, processing, and thinking of human drivers, but to make it a reality. And this is a good thing, since driver error causes more than 94 percent of motor vehicle accidents, according to the National Highway Traffic Safety Administration.

Aptiv has developed the underlying electrical architecture, software and computing expertise, both in-house and by partnering with companies and universities on the leading-edge of autonomous driving technology.
