Euro NCAP rates DISTRONIC on the Mercedes-Benz E-Class Very Good

Euro NCAP's 2023 tests gave DISTRONIC on the E-Class 99% for safety backup. A cabin camera checks the driver for microsleep, and the car stopped safely for an unresponsive driver.

  • Not rated a person

    Euro NCAP measured the system on test tracks, and no crash outcome for drivers or passengers is reported.

Depth runs from 1, a convenience or time saved, to 5, a life or a livelihood preserved.

Status
Reported benefit.
Evidence

foundstudiedreportedclaimed

Two independent assessment reports support the benefit.

The system’s part
Not isolated. Euro NCAP tested the car with the system switched on, so the scores describe the system's own responses on the track. There was no run without the system for comparison. Euro NCAP describes a cabin camera and real-time camera inputs but does not say whether they use trained models.

    The Mercedes-Benz has an internal camera to check for 'microsleep' and combines this information with steering wheel input to monitor driver status.

  2. Assessment report, by authors with no tie to the system.

    Euro NCAP. Mercedes-Benz E-Class - Assisted Driving Datasheet 2023 (version 231023), October 2023. The tested car was an E400e.

    In case of an unresponsive driver, the E-Class automatically moves to the slowest lane and performs a controlled stop.

Details

AI system

Workflow

An internal camera checks for microsleep, and the car combines this with steering input. The car combines map-based speed limit information with real-time camera inputs. The system adapts speed for curves and junctions ahead.

Follow-up

Conditions for replication

The radar and camera stay unblocked, since the car otherwise warns the driver and keeps the system off. The driver stays engaged while the car monitors the driver's state.

Entry details

Sector

Road vehicle crash avoidance / assisted driving.

Purpose

Mercedes-Benz built Active Distance Assist DISTRONIC to help the driver control speed, distance and steering.
