An independent assessment report supports the benefit.

The system’s part
Not isolated. Euro NCAP tested the car with Toyota Safety Sense switched on, so the scores reflect the system's own responses. There was no run without the system for comparison. Euro NCAP mentions real time camera inputs and a radar but does not describe AI or show that the system learns from data.

    Euro NCAP. Toyota bZ4X 2025 Assisted Driving grading: Very Good (Toyota Safety Sense). Published 4 June 2025.

    'Toyota Safety Sense', as fitted to the Toyota bZ4X, balances a high level of Vehicle Assistance with a similar level of Driver Engagement. Combined with excellent safety back-up, the system, overall, offers Very Good highway assistance.
    The car responds to avoid or mitigate a collision in most of the test scenarios for automatic cruise control.

Details

AI system

Workflow

The system combined map-based speed limit information with real time camera inputs. It adapted its speed for curves ahead. It locked out the assistance after repeated hands-off warnings.

Follow-up

Conditions for replication

The driver stays attentive, since the indirect driver monitoring does not detect distraction. The driver slows for junctions, since the system adapts its speed for curves only.

Entry details

Sector

Road vehicle crash avoidance / assisted driving.

Purpose

Toyota built the highway assistance of Toyota Safety Sense to help the driver with speed, following distance, steering and lane changes.
