An Assessment of the Tesla Model 3's Forward Collision Warning and
Automatic Emergency Braking Systems against a Stationary Pedestrian
Target 2024-01-2482
A total of 93 tests were conducted in daytime conditions to evaluate the
effect on the Time to Collision (TTC), emergency braking, and avoidance
rates of the Forward Collision Warning (FCW) and Automatic Emergency
Braking (AEB) provided by a 2022 Tesla Model 3 against a 4ActivePA adult
static pedestrian target. Variables that were evaluated included the
vehicle speed on approach, pedestrian offsets, pedestrian clothing, and
user-selected FCW settings. As a part of the Tesla’s Collision Avoidance
AssistTM, these user-selected FCW settings change the timing of the
issuance of the visual and/or audible warning provided. This testing
evaluated the Tesla at speeds of 25 and 35 miles per hour (mph) versus a
stationary pedestrian target in early, medium, and late FCW settings.
Testing was also conducted with a 50% pedestrian offset and 75% offset
conditions relative to the right side of the Tesla. The pedestrian
target was clothed with and without a reflective safety vest to account
for different conspicuity during the testing. The TTC at FCW and AEB,
emergency braking deceleration and the avoidance rates were compared
between different settings and test parameters. The test data was also
compared against the IIHS pedestrian tests at different speeds and
scenarios.
