Toyota Safety Sense

The road can be unpredictable. That's why Toyota has introduced Toyota Safety Sense (TSS). TSS is designed to help protect drivers, passengers, people in other vehicles on the road, and pedestrians. TSS is comprised of multi-feature active safety packages anchored by automated pre-collision warning and braking. TSS is designed to support the driver's awareness, decision-making, and vehicle operation over a wide range of speeds under certain conditions. Packaged together with an integrated system, TSS features help address three key areas of accident protection: mitigating or preventing frontal collisions, helping to keep drivers within their lane, and enhancing road safety during nighttime driving. Always drive safely, obey traffic speed limits and laws, and focus on the road while driving.

TSS is offered in the form of two packages: Toyota Safety Sense C (TSS-C) for compact vehicles and Toyota Safety Sense P (TSS-P) for midsize and large vehicles.

Toyota Safety Sense C features three proprietary active safety technologies, and combines a camera and laser for outstanding performance and reliability. The package can help mitigate or prevent collisions in a wide range of vehicle speeds under certain conditions. These features are:
  • Pre-Collision System (PCS) - Vehicle Detection
  • Lane Departure Alert (LDA)
  • Automatic High Beams (AHB)
Toyota Safety Sense P combines an in-vehicle camera and front-grille-mounted millimeter wave radar for enhanced performance and more functionality. TSS-P features are:
  • Pre-Collision System with Pedestrian Detection (PCS w/PD) - Vehicle & Pedestrian Detection
  • Lane Departure Alert with Steering Assist (LDA w/SA)
  • Automatic High Beams (AHB)
  • Dynamic Radar Cruise Control (DRCC) 
Below is an explanation of each of these cutting-edge features:

With TSS-C, Pre-Collision System (PCS) uses an in-vehicle camera and laser to help detect the vehicle in front of yours. When PCS determines that the possibility of a frontal collision with that vehicle is high, it prompts the driver to take evasive action and brake by using an audio and visual alert. If the driver notices the hazard and brakes, the system may provide additional braking force using Brake Assist. If the driver does not brake in a set time and the system determines that the possibility of a frontal collision with a preceding vehicle is extremely high, the system may automatically apply the brakes, reducing speeds in order to help the driver reduce the impact and, in certain cases, avoid the collision.

With Toyota Safety Sense P, PCS uses an in-vehicle camera and front-grille-mounted millimeter-wave radar to help detect the vehicle in front of yours. In certain conditions, the PCS system included with the TSS-P pacakge may also help to detect a pedestrian in front of your vehicle. The in-vehicle camera of PCS detects a potential pedestrian based on size, profile, and motion of the detected pedestrian. However, a pedestrian may not be detected depending on the conditions, including the surrounding brightness and the motion, posture, size, and angle of the potential detected pedestrian, preventing the system from operating or engaging.

TSS-P equipped vehicles include Dynamic Radar Cruise Control (DRCC). On highways, DRCC functions similarly to conventional "constant speed" cruise control in that it helps vehicles travel at a consistent speed set by the driver. The difference is that this system adds a vehicle-to-vehicle distance control mode which assists the driver by adjusting the vehicle speed (within a set range) to help maintain a preset distance to a preceding vehicle when the preceding vehicle is traveling at a lower speed.

Automatic High Beams (AHB), found in both TSS-C and TSS-P, is a safety system designed to help drivers see more of what's ahead at nighttime without dazzling other drivers. When enabled, AHB uses an in-vehicle camera to help detect the headlights of oncoming vehicles and taillights of preceding vehicles, then automatically switches between high and low beams as appropriate to provide the most light possible and enhance forward visibility. By using high beams more frequently, the system may allow earlier detection of pedestrians and obstacles.

If Lane Departure Alert determines that the vehicle is starting to unintentionally deviate from its lane, the system alerts the driver with an audio and visual alert. When the alerts occur, the driver must check the surrounding road situation and carefully operate the steering wheel to move the vehicle back to the center part of their lane.

In addition to the alert function of LDA, TSS-P equipped vehicles with Electronic Power Steering will also feature a Steering Assist function. When equipped and enabled, if the system determines that the vehicle is on a path to unintentionally depart from its lane, the system may provide small corrective steering inputs to the steering wheel for a short period of time to help keep the vehicle in its lane.
