📖 The Quick Answer
Hyundai SmartSense bundles Forward Collision-Avoidance Assist (FCA, which is AEB plus pedestrian and cyclist detection), Lane Keeping Assist, Lane Following Assist, Smart Cruise Control with Stop and Go, Blind-Spot Collision-Avoidance Assist, Rear Cross-Traffic Collision-Avoidance Assist, Safe Exit Warning, Driver Attention Warning, and High Beam Assist. Highway Driving Assist 2 is the hands-on partial-automation feature on Palisade Calligraphy, Genesis G80, and other top trims.
⚙ How It Works (Sensors and Algorithm)
Hardware is a forward camera behind the windshield, a front radar in the lower bumper, two rear corner radars, and ultrasonic sensors. Highway Driving Assist 2 adds two front corner radars. The ADAS ECU fuses inputs and controls throttle, brake, and the column-mounted electric power steering. Hyundai pushed a major software revision in MY2022 that significantly reduced false AEB activations.
🛡 What It Protects Against
Rear-end collisions, lane departures, blind-spot lane changes, reverse cross-traffic, and pedestrian or cyclist strikes. IIHS rates Tucson, Santa Fe, Palisade, Sonata, and Elantra with SmartSense as Top Safety Picks.
⚠ Limitations and When It Fails
The first-generation SmartSense (2018 to 2020) had a known issue with camera saturation in low sun angles. Like all camera-based systems, it depends on clear lane paint and a clean windshield. After a windshield replacement, both static and dynamic recalibration are required (Hyundai TSB 19-BE-001).
🚗 Which Vehicles Have It
Every 2022+ Hyundai has SmartSense standard. Lineup includes Elantra, Sonata, Tucson, Santa Fe, Palisade, Kona, Venue, Santa Cruz, Ioniq 5, and Ioniq 6. Genesis G70, G80, G90, GV60, GV70, and GV80 use the same hardware under the Genesis Active Safety name.
