"Light applications of the brake-to shed a few miles per hour, not to conduct an emergency stop-will slow the car, which then resumes its original speed, much the same way you have always been able to apply the throttle to temporarily speed up while using cruise control. Drive Assist Pro takes this collaborative approach between the car and driver and runs with it."
"All of this is possible thanks to the CLA being what the industry calls a software-defined vehicle. Four powerful computers run all the electronics, rather than dozens and dozens of discrete black boxes. One of those computers is (of course) from Nvidia-that company's Orin, which handles things like perception and path planning. "We completely elevated our autonomous driving stack. It is no longer on a rule-based stack,""
Light brake applications slow the car a few miles per hour and then the vehicle resumes its original speed, similar to temporary throttle use with cruise control. Drive Assist Pro anticipates required lanes, reads stop signs and traffic lights, and detects and slows for speed bumps. In a 20-minute urban drive the system required no interventions, though some demos were confused by human crosswalk attendants. The CLA maintained safe legal speeds, handled construction zones, and navigated around double-parked cars, while full stops at stop signs can delay drivers behind. The CLA is a software-defined vehicle running four powerful computers and uses an end-to-end AI driving stack.
