Lexus to Include New Safety System in all Models

June 19, 2019—In a move to help prevent accidents before they happen, the Lexus Safety System+ will be a standard feature in all U.S. Lexus vehicles starting with the 2020 model year.

The Lexus Safety System+ is an integrated suite of four advanced active safety packages anchored by automated pre-collision warning and braking. They include:

  • Pre-collision system with pedestrian detection
    This system is engineered to help detect a vehicle or pedestrian in front of the Lexus. Should the system detect a pedestrian or a potential frontal collision, it's designed to activate an audible and visual alert while preparing Brake Assist for increased braking response.
  • Lane departure alert
    This system utilizes a high-resolution camera to monitor visible lane markings and determine the vehicle's position within a lane. If an inadvertent lane departure or potential departure due to swaying is detected at speeds above 32 mph, the system alerts drivers.
  • Intelligent High Beams
    To help provide added visibility for the Lexus driver as well as other motorists, Intelligent High Beams offer added illumination to help keep the driver focused on the road. When the road ahead is clear, the system defaults to high-beam mode.
  • Dynamic Radar Cruise Control
    This system uses radar and camera technology to help maintain a preset speed and following distance from the vehicle ahead. 

The development of many Lexus vehicle safety features benefits from the Total Human Model for Safety, or THuMS, virtual crash dummy software. Un­like typical dum­my mod­els which provide 119 data points, THuMS provides millions of data points and rep­re­sents ac­tu­al humans in de­tail. 

This means crash tests can be conducted to determine the impact  of potential collisions on a nearly endless variety of humans, from large to smal.
