WHAT IS LEXUS SAFETY SYSTEM+?

Car manufacturers continuously enhance and refine their Advanced Driving Assistance Systems (ADAS) to bolster safety and instill confidence in drivers. The objective is to progress towards Level 3 and beyond autonomous driving capabilities. The Lexus Safety System+ (LSS+) serves as a prime example of an ADAS suite in a perpetual state of improvement.

Lexus and its parent company, Toyota, initially unveiled LSS+ with the launch of the redesigned 2016 Lexus RX. This ADAS package is intricately woven into an integrated system concentrating on three pivotal aspects of accident prevention: identification and mitigation of frontal collisions, ensuring vehicles remain securely within their lanes, and augmenting safety during nocturnal driving. Essentially, its core purpose revolves around aiding drivers to retain control and steer clear of accidents in routine driving scenarios.

To comprehend the latest iteration of LSS+ fully, it is essential to delineate the ADAS components present in its preceding versions. Each level in this progression lays the groundwork for the subsequent one, culminating in the development of LSS+ 3.0. Broadly speaking, LSS+ encompasses four fundamental systems:

LEXUS SAFETY SYSTEM +

  • Adaptive cruise control (works at speeds over 25 mph)
  • Forward-collision warning
  • Pedestrian detection
  • Automatic emergency braking
  • Lane-departure warning
  • Lane-keeping assistance
  • Automatic high-beam headlights

LEXUS SAFETY SENSE + 2.0

  • Upgraded radar and camera units
  • All-speed adaptive cruise control (including stop-and-go capability)
  • Cyclist detection during daytime
  • Pedestrian detection during daytime and in low-light conditions
  • Preceding vehicle detection during daytime and in low-light conditions
  • Lane-centering assistance (gives LSS+ 2.0 Level 2 hands-on driving-assist technology)
  • Traffic-sign recognition (reads road signs and displays the data for the driver)

LEXUS SAFETY SENSE + 2.5

  • Improved adaptive cruise control (more quickly overtakes slower vehicles when the driver changes lanes to go around them, the process now begins when the driver signals the lane change)
  • Improved lane and road edge recognition capability
  • Intersection turn assistance (identifies when it is unsafe to make a left turn across traffic or when pedestrians are in a crosswalk and can warn the driver or brake the vehicle to prevent a collision)
  • Automatic emergency steering (when the driver makes a sudden steering change, such as to avoid an object or correct a potential lane departure, this evasive steering-assistance technology helps to keep the vehicle under control)

LEXUS SAFETY SENSE + 3.0

The LSS+ 3.0 system builds upon LSS+ 2.5 with newly added functionality. The 3.0 version became available initially with the redesigned 2022 Lexus NX crossover SUV. Here are the system’s highlights:

  • Risk Avoidance Emergency Steer Assist: This system will help you avoid collisions in your lane of traffic by assisting with braking and steering as you make evasive maneuvers.
  • Left Turn Oncoming Vehicle Detection Braking: If you turn left in front of approaching traffic, this system will warn you and automatically apply the brakes.
  • Right & Left Turn Oncoming Pedestrian Detection & Braking: If you turn left or right in front of a pedestrian or cyclist, this system will warn you and automatically apply the brakes.
  • Oncoming Vehicle Detection: This feature augments the existing pre-collision system, warning you and automatically applying the brakes when a possible frontal collision is detected.
  • Adaptive Cruise Control with Curve Speed Management: Although adaptive cruise control is not new, this feature’s ability to maintain constant speed in corners is a new addition to this feature.

It’s important to note that the specific features and their availability may vary across different Lexus models and model years. The latest iteration has been integrated in the recent models such as the Lexus LM, Lexus TX, Lexus LBX, Lexus GX, Lexus LX among others. The Lexus Safety System + demonstrates the brand’s commitment to prioritizing safety and integrating advanced technologies to enhance driver confidence and reduce the risk of accidents on the road.
