But ProPilot 2.0 requires the human driver to stay alert and keep their eyes on the road (as confirmed by driver monitoring), clearly assigning the OEDR task to the driver. In a Level 3 system, the system is handling OEDR and the person in the driver’s seat need not provide continuous attention to the road. SAE J3016 Simplified Logic Flow Diagram for Assigning Driving Automation Level to a Feature (Figure. For Level 3, OEDR is handled by the Automated Driving System (ADS) the driver retains responsibility to be “receptive to ADS-issued requests to intervene.” The flow chart below from SAE J3016 is a great way to negotiate the “levels maze.” Table 1 in SAE J3016 states that for Level 2, “the driver completes the OEDR subtask and supervises the driving automation system,” immediately taking control when conditions warrant. OEDR is defined in detail in the standard. The defining difference between Level 2 and Level 3 comes with OEDR, or “Object and Event Detection and Response.” OEDR is the geek term for doing what any driver does: keep an eye on any factors that might affect driving, especially safety, and deal with it (a core aspect of the “Dynamic Driving Task”). It succeeds in providing a manner to talk about automated driving but having a “Level X” system on your car does not tell you what its limits are. Only the manufacturer can tell you this. Some are intended for highway use and will not activate at lower speeds. SAE 3016 is a definitions document, not a performance document.

Nissan stresses that the driver must remain attentive and be prepared “to immediately take manual control of the steering wheel when conditions of the road, traffic, and vehicle require it.” Similar to SuperCruise, lack of response by the driver will cause the vehicle to activate hazard lights and come to a graceful stop, opening an audio connection with an emergency call center.įor both Level 2 and Level 3, the driver support system is providing “sustained lateral and longitudinal vehicle motion control.” The “sustained control” of steering is a bit of a murky point. Different systems will handle different degrees of road curvatures and react in particular ways to lane markings for at freeway exits. For the freeway-to-freeway interchange feature noted above, ProPilot 2.0 handles a lane branching in two directions, based on the designated route. The system supports hands-off driving while cruising in a single lane when a lane change is needed, the driver is prompted to place their hands on the wheel and press a button to approve the maneuver, what I call a “supervised lane change.” The system then safely controls steering, brakes, and throttle to perform the maneuver based on data from sensors that can see in all directions. ProPilot 2.0 goes one step further with “navigated driving,” providing ramp-to-ramp highway driving based on a route entered into the navigation system by the driver. GM added a driver monitoring system which is key to allowing hands-off capability, providing some degree of confidence that the system is being used responsibly. The Nissan system evokes the Cadillac SuperCruise™ system introduced in 2017, which controls steering, braking, and throttle while on an approved highway, as long as the driver is continuously monitoring the driving environment. As a start, a review of the capabilities implemented by Nissan in ProPilot 2.0 are in order.
