Stay alert: Europe's 2026 drive with DSM

In order to reduce the number of road accidents caused by human factors, Driver State Monitoring (DSM) solutions have been developed. These systems are capable of detecting instances of impaired driving, such as drowsiness, distraction, driving under the influence, sudden illnesses, and aggressive driving. These solutions are also required by the European Regulation which, starting from 2026, it will be mandatory to equip all new vehicle types with the Advanced Driver Distraction Warning System (ADDWS).


Reply's digital drive for enhanced monitoring

Reply has developed a driver state monitoring system based on the analysis of behavioural patterns (without the need for biometric data), and the creation of a Digital Twin of the driver. This model of nominal behaviour is adapted to each specific driver's driving style by collecting telemetric data on an AWS platform and analysing the historical usage on the road.

To validate this algorithm, a testing framework has been developed, which includes an in-cabin monitoring system capable of analysing drivers' biometric data and validating instances of inappropriate driving activities.

Innovative framework features


Detects impaired driving without the necessity to tap into biometric information.

Driver personalization

Create a Digital Twin tailored to each verified driver, reflecting their unique driving patterns.

On-device processing

Engineered to operate directly on the vehicle's ECU, minimising lag and bypassing network limitations.

Self-regulating labelling

Streamlines the data tagging and system verification process by using real-time insights gathered by an in-cabin camera monitoring setup.

Seamless vehicle connectivity

Anchored on a unified vehicle connectivity framework, it's adept at transmitting telemetry insights to distant databases and facilitating over-the-air model updates.

Advanced biometrics

Utilises computer vision techniques to derive biometric insights, ensuring precise assessment of driver distraction levels.

X-in-the-loop integration

A synergistic, scalable co-simulation environment combined with a realistic vehicle model is the basis for a versatile tool that can be used in development and validation, especially for assessing traffic scenarios.

Synthetic data generation

Generation of high-fidelity vehicle and traffic data from a simulation for automotive system development and validation.

Key advantages

As autonomous driving technologies continue to break barriers, the synergy between real-world and simulated data stands as a testament to the industry's commitment to innovation, safety, and progress. Specifically, Reply's solution embodies this forward-thinking approach, harnessing the power of high-fidelity simulations for advanced and personalised driver state monitoring.


Cost-Efficiency &

Unlike real-world data acquisition which involves extensive sensorisation and experimentation, simulated environments can produce massive amounts of data in a fraction of the time and cost.



Simulated driving scenarios mitigate the risks tied to real-world anomalies, ensuring driver safety isn't compromised during data collection.


Reproducibility &


With simulations, one can reproduce diverse driving scenarios, ensuring a holistic dataset that mirrors various real-world conditions.


Dynamic Interaction

From capturing subjective behaviour with a real driver in the loop, to interactions with smart road infrastructure, simulations offer a detailed and realistic portrayal of on-road conditions.



The certification processes of these simulations are already aligned with EU GSR legislation, paving the way for more streamlined, legal, and standardised data collection processes.


From ideas to innovative projects

The autonomous driving technology and high-fidelity simulation are tangible realities at Area42 labs: the Reply’s development centre is dedicated to experimenting with and transforming creative ideas into reality and it is where real prototypes can be felt, tested, and adapted to any business context.
This is the future of autonomous driving, and it's being shaped right now at Area42.
