What is Toyota Safety Sense 2.5 Plus?

Jessica Choksey | Jul 23, 2020

Advanced driving assistance systems (ADAS) are continually elevating vehicle safety across the automotive industry as a steady stream of newly developed technologies are pioneered and brought to market. The most recent example of this is Toyota Safety Sense (TSS) 2.5 Plus, the newest iteration of the automaker’s comprehensive suite of integrated safety technologies focused on eliminating or mitigating three primary types of accidents: frontal collisions, undesired lane departures, and nighttime mishaps.

Designed with the premise that avoiding an accident is a better course than simply surviving one, this bundle of enhanced safety features is set to debut on the 2021 Toyota Camry later this year and features advancements over the previous TSS 2.0 system.

TSS 2.5+ builds on the previous TSS suites by enhancing two of its existing functionalities: Pre-Collision System with Pedestrian Detection (forward collision warning with pedestrian detection and automatic emergency braking) and Full-Speed Dynamic Radar Cruise Control (adaptive cruise control). Additionally, TSS 2.5+ continues to offer lane-departure warning with lane-keeping assistance (featuring both steering assistance and road-edge detection), lane-centering assistance, automatic high-beam headlights, and road sign assistance.

This next phase of TSS 2.5+ brings the forward collision warning and automatic braking technology to a new level of accident avoidance by making it more proactive in its functionality. Beyond detecting the vehicle ahead, the system can also sense a preceding bicyclist or pedestrian in both daytime and low-light conditions. And at an intersection, the TSS 2.5+ will now detect an oncoming vehicle, bicyclist, or pedestrian during a left-hand turn and provide audio and visual alerts as well as perform automatic braking when necessary. The goal is to maximize a vehicle’s ability to avoid a collision that previously may have been deemed unavoidable.

As before, adaptive cruise control is part of the TSS 2.5+ system, but now includes a new feature that allows for a more seamless and anticipatory approach in passing maneuvers. When approaching a slower vehicle from behind, the system automatically begins to accelerate once the driver engages the turn signal with steering input. The increase in speed readies the vehicle to confidently change lanes and overtake the vehicle in front, eliminating the delay in acceleration that typically plagues adaptive cruise control. After the lane change occurs, acceleration continues until the vehicle reaches the preset cruising speed. At that point, the driver can decide when to safely move back into the original lane or stay in the new lane.

Overall, TSS 2.5+ is designed as an integrated system, utilizing camera, radar, and an advanced computer with more processing power than ever, operating with greater sophistication and wider functionality over its previous iteration.

After its debut in the 2021 Camry, other models in the Toyota lineup are expected to adopt the upgraded TSS 2.5+ tech array in the future.
