Comparative Analysis of FCW and AEB Performance: 2020 Jeep Gladiator vs. 2020 Tesla Model 3 Against Slow-Moving Target in Varying Light Conditions.

A total of 67 high speed tests (70 mph and 75 mph) were performed on a 2020 Jeep Gladiator and a 2020 Tesla Model 3 to evaluate and compare the performance of Forward Collision Warning (FCW) and Automatic Emergency Braking (AEB) in daytime and nighttime conditions. These tests involves high closing speeds of 60 mph and 65 mph against a slow moving live vehicle target (moving at 10 mph and 15 mph). Consistent and repeatable FCW was observed across all the tests. At a closing speed of 60 mph, the average TTC at the onset of FCW for the Jeep was 2.21 seconds and it was 2.55 seconds for the Tesla. At the same closing speed, the average TTC at the onset of AEB for the Jeep was 1.89 seconds and it was 1.56 seconds for the Tesla. At a closing speed of 65 mph, the average TTC at the onset of FCW for the Jeep was 2.29 seconds and it was 2.37 seconds for the Tesla. At the same closing speed, the average TTC at the onset of AEB was 1.88 seconds for the Jeep and 1.39 seconds for the Tesla. The lighting conditions had no impact on the average TTC at FCW when compared within the tests performed on the same vehicle. Across different lighting conditions, the Tesla warned slightly earlier compared to the Jeep but the AEB in the Jeep engaged earlier compared to the Tesla.
