Why Vehicle Control Is Becoming a Critical Factor in Autonomous Systems
The Interplay of Drive-by-Wire, Safety-by-Wire(®),and Control-by-Wire®in Real-World Operation
(PresseBox) - An autonomous commercial vehicle is on the road in daily operation. The route is known, the surroundings are mapped, and the sensors provide stable data. Then the situation changes: The road surface becomes uneven, a sensor reading deviates briefly, an actuator reacts with a delay. The vehicle recognizes the situation. The question is not whether it recognizes it. The crucial question is: Does the vehicle remain controllable at that moment?
Autonomous vehicles are often defined by sensors, software, and artificial intelligence. In practice, however, the focus shifts precisely at such points. What matters is not only whether a system understands its environment, but whether it can execute movement safely and controllably at all times under real-world conditions.
This capability is no minor detail. It determines whether vehicles function reliably, whether processes remain stable, and whether automation can be deployed in an economically viable manner—especially in autonomous, teleoperated, or highly automated applications where there is no longer any possibility of immediate human intervention. As the degree of automation increases, this fallback level disappears—and with it the implicit assumption that control can be ensured from the outside in case of doubt.
“We describe this relationship across three levels. Drive-by-Wire is the technical execution level at which steering, braking, and propulsion are electronically controlled. Safety-by-Wire® represents the architecture that safeguards these functions,” explains Kevin Arnold, CEO of Arnold NextG. “Control-by-Wire® describes the interaction of both levels as system behavior—that is, the ability to keep vehicle movement predictable and controllable at all times, even under disturbances, signal deviations, or degraded conditions.”
Vehicle control as system behavior
This fundamentally shifts the perspective on vehicle control. It is no longer understood as the sum of individual functions, but as system behavior. What matters is not whether steering, braking, or propulsion function on their own, but whether the vehicle remains predictable and controllable even under deviations, malfunctions, or degraded conditions.
The NX NextMotion platform implements this approach technically. The architecture combines Drive-by-Wire and Safety-by-Wire®in a multi-redundant, fail-operational system logic designed to keep vehicle movement controllable even under less-than-ideal conditions. The focus here is less on individual functions and more on the stability of the overall system during operation.
Why Availability Becomes a System-Wide Issue
This distinction becomes particularly apparent in commercial fleets and autonomous applications. Availability does not arise solely from functioning components, but from a system’s ability to handle deviations, detect errors early, and respond to them in a controlled manner. In this context, vehicle control becomes a decisive economic factor.
Against this backdrop, the term Control-by-Wire®is also gaining significance. It describes not an additional function, but a shift in perspective: away from individual technologies, toward the question of how vehicle motion can be reliably controlled as an overall system. “Autonomy does not begin with perception, but with controlled motion,” says Arnold. “When systems take on responsibility, they must also be able to physically bear that responsibility.”
This also shifts the role of Drive-by-Wire. It is no longer merely a technological foundation but part of an overarching control architecture designed to keep movement stable, predictable, and controllable under real-world conditions.
