Volvo has presented new safety technologies for its heavy-duty trucks in Brazil, with a primary focus on a system designed to intervene when a driver becomes unresponsive. The solution, named Controlled Stop, is specifically engineered for scenarios where the operator may be dozing off or losing the ability to steer the vehicle effectively.
The technology monitors whether the driver's hands are on the steering wheel and can identify risk indicators such as closed eyes. Upon detecting a concerning situation, the system initiates a sequence of warnings and waits for a reaction before escalating to more decisive measures. These innovations are scheduled to be showcased to the public at Fenatran 2026, a transportation sector fair set to take place in November in São Paulo.
The operational logic of the autonomous stopping feature follows a strict protocol. When the system identifies that the driver is not responding, it first issues alerts. If there is no reaction, the truck activates lane-keeping assistance to make steering corrections and maintain the vehicle on its path. Should the lack of response persist, the service brakes are engaged to bring the truck to a full stop.
During this emergency maneuver, the hazard lights are automatically activated. Once the vehicle has come to a halt, the doors are unlocked, according to the manufacturer. Volvo emphasizes that this resource is designed for emergency situations and does not render the truck autonomous; driving remains the responsibility of the driver, while the technology serves as an additional safety layer.
In addition to the stopping system, Volvo introduced the second generation of its Attention Detector. This updated version includes a sensor capable of tracking the driver's eye movements, identifying when eyes remain closed or deviate downward and sideways for a specific period. If signs of inattention persist, the alerts become progressively more frequent and audible.
The company also presented the Safety Score, a report integrated into the Volvo Connect application that allows fleet managers to monitor driving-related indicators. The data evaluated includes harsh braking, collision warnings, stability control activations, and ABS usage. This tool aims to help companies identify risky behaviors and guide training programs to make trips safer.
This initiative underscores Volvo's ongoing commitment to the safety of heavy vehicle operators. It follows recent developments by the Swedish brand, such as the launch of "virtual fence" technology designed to limit truck speeds.
