How Does the Toyota Pre-Collision System Work?

Toyota Safety Sense Banner

Toyota Safety Sense™ has received praise from both everyday drivers and industry experts alike, and it’s for good reason. The Toyota Pre-Collision System is one of the best known features in this safety suite, sensing the possibility of an accident and warning the driver to help reduce the risk of collision. How does it work? With cameras and lasers. Really! If necessary, the Toyota Pre-Collision System can even bring a vehicle to a full stop.

Toyota Tech Built to Reduce Accidents

Although you now have a general idea about how this pre-collision system works, you may be curious how it can further assist in your Florence commutes. 

  • A Toyota model with the Pre-Collision System is outfitted with both a front-facing camera and a laser (it uses an invisible beam, so you won’t see a colored dot). 
  • These components gauge the distance between your vehicle and any obstacles ahead. 
  • Taking your speed into account, the system determines how likely a collision may be. How does it work?
    • The camera can sense when the vehicle in front of you is getting larger (closer) or smaller (farther).
    • The Pre-Collision System can sense when the laser is taking more or less time to hit a vehicle in front of you as well, telling you whether you’re getting closer or farther.
    • Both of these systems have a limit, when you’re too close and your vehicle speed is too high, the Pre-Collision System will kick into gear.
  • If the system believes that a collision may occur, it will provide an audiovisual alert to notify you to manually apply the brake as soon as possible.
  • If you do not apply the brakes, the Toyota Pre-Collision System may apply the brakes automatically or deploy them at full force with brake assist.

While it is still essential to drive with caution, the Toyota Pre-Collision System can help you drive with more confidence on the roads of Huntsville. 


Toyota Pre-Collision System with Pedestrian Detection

Currently, there are a couple of different versions of the Toyota Pre-Collision System available. Toyota Safety Sense™ P (TSS P) or Toyota Safety Sense™ 2.0 (TSS 2.0) are the most common options. With these two versions, the Toyota Pre-Collision System also includes Pedestrian Detection.

How does Pedestrian Detection work? This feature uses an additional grille-mounted system that employs millimeter-wave radar to check your surroundings for smaller objects that could be missed by the standard PCS. Pedestrian Detection looks at the size, shape, and motion of this smaller object to identify a pedestrian and apply the brakes if needed.

Which Toyota Models Have a Pre-Collision System?

Many models throughout the Toyota lineup can be equipped with a pre-collision system. Listed below are your current options:

  • Crossovers, SUVs, and Minivans: C-HR, Land Cruiser, Highlander, Highlander Hybrid, RAV4, RAV4 Hybrid, Tundra, Sequoia, Tacoma, Sienna
  • Cars and Hatchbacks: Avalon, Avalon Hybrid, Camry, Camry Hybrid, Corolla, Corolla Hybrid, Prius, Prius Prime, Prius c, Yaris Hatchback

Highlights of Toyota Safety Sense™

There are three available Toyota Safety Sense™ packages depending on your vehicle of choice. Listed below are the features found on the newest and most comprehensive version of the system, Toyota Safety Sense™ 2.0 (TSS 2.0):

  • Pre-Collision System with Pedestrian Detection (PCS w/PD)

  • Lane Tracing Assist (LTA)
  • Automatic High Beams (AHB)
  • Dynamic Radar Cruise Control (DRCC) or Full-Speed Range DRCC
