   • Impact: PCS has been shown to significantly reduce the likelihood of frontal collisions, particularly those involving pedestrians.
2. Lane Departure Alert with Steering Assist (LDA):
   • Functionality: LDA uses a camera to monitor lane markings and alerts the driver if the vehicle begins to drift out of its lane without signaling. If the driver does not respond, the system can provide gentle steering assistance to guide the vehicle back into the lane.
   • Impact: LDA helps prevent accidents caused by unintentional lane departure, which is a common factor in many highway accidents.
3. Automatic High Beams (AHB):
   • Functionality: AHB automatically switches between high and low beams based on the presence of other vehicles. This ensures optimal visibility without dazzling other drivers.
   • Impact: AHB improves nighttime visibility, reducing the risk of accidents in low-light conditions.
4. Dynamic Radar Cruise Control (DRCC):
   • Functionality: DRCC uses radar to maintain a set distance from the vehicle ahead, automatically adjusting speed to match traffic flow. This reduces the need for constant speed adjustments by the driver.
   • Impact: DRCC reduces driver fatigue and helps maintain a safe following distance, particularly in heavy traffic.
5. Road Sign Assist (RSA):
   • Functionality: RSA uses a camera to detect and recognize road signs, displaying relevant information (such as speed limits) on the vehicle’s dashboard.
   • Impact: RSA helps drivers stay informed about road conditions and regulations, reducing the likelihood of speeding and other traffic violations.

Toyota Safety Sense 2.0 and Beyond

In 2018, Toyota introduced Toyota Safety Sense 2.0, an enhanced version of the original TSS suite. TSS 2.0 includes several new features and improvements, such as:

   • Impact: BSM helps prevent lane-change accidents, which are a common cause of collisions on highways.
2. Rear Cross-Traffic Alert (RCTA):
   • Functionality: RCTA warns the driver of approaching vehicles when reversing out of a parking space or driveway. It is particularly useful in crowded parking lots where visibility is limited.
   • Impact: RCTA reduces the risk of collisions when reversing, particularly in situations where the driver’s view is obstructed.
3. Parking Assist with Automatic Braking:
   • Functionality: This system uses sensors to detect obstacles during parking maneuvers and can automatically apply the brakes if a collision is imminent.
   • Impact: Parking assist helps prevent low-speed collisions, particularly in tight parking spaces.
4. Adaptive Front Lighting System (AFS):
   • Functionality: AFS adjusts the direction of the headlights based on steering input and vehicle speed, improving visibility around curves and corners.
   • Impact: AFS enhances nighttime driving safety by providing better illumination of the road ahead.
5. Driver Monitoring System (DMS):
   • Functionality: DMS uses cameras and sensors to monitor the driver’s attention level and alertness. If the system detects signs of drowsiness or distraction, it will alert the driver to take a break.
   • Impact: DMS helps prevent accidents caused by driver fatigue or inattention, which are significant factors in many road accidents.
