Lexus in 2015 is launching the "Lexus Safety System +" package, a set of active safety technologies designed to help prevent or mitigate collisions across a wide range of vehicle speeds.
Lexus vehicles already feature a wide range of safety technologies and systems based on the Integrated Safety Management Concept. But this latest package is “aimed at further encouraging the uptake of safety technologies,” the automaker said. It will be rolled out across all Lexus models in Japan, North America and Europe by the end of 2017.

Lexus Safety System + integrates several of Lexus's existing active safety technologies: the Pre-Collision System (PCS) helps prevent and mitigate collisions. Lane Departure Alert (LDA) helps prevent vehicles from departing from their lanes. Automatic High Beam (AHB) helps ensure optimal forward visibility during nighttime driving.
As part of a multi-faceted approach to active safety, the Lexus Safety System + package combines millimeter-wave radar with a camera to ensure high reliability and performance.
The Lexus Safety System + includes:
Pre-collision system with pedestrian detection function (PCS) – This system uses millimeter-wave radar and a camera to detect pedestrians in addition to vehicles. To help prevent or mitigate collisions, the system activates an audio and visual alert in addition to brake assist, followed by automated braking if the driver does not brake in time.
Lane Departure Alert (LDA) – LDA uses a camera to detect white and yellow lane markings. If the vehicle starts to deviate from a lane, LDA alerts the driver with an audio-visual alert and steering wheel vibration. Some vehicles are also equipped with Lane Keep Assist, which controls power steering to make it easier for the driver to remain within lane markings.
Automatic High Beam (AHB) – AHB helps ensure excellent forward visibility during nighttime driving. It uses a camera to detect the headlights of oncoming vehicles and the tail lights of vehicles ahead, and then automatically switches between high beams and low beams to prevent blinding other drivers.
Radar Cruise Control – On highways, Radar Cruise Control uses millimeter-wave radar to detect preceding vehicles and determine their speed. It then adjusts vehicle speed -- within a set range -- to ensure there’s a safe distance between vehicles. By using a forward-facing camera and millimeter-wave radar to monitor vehicles moving into or out of the lane, Radar Cruise Control helps maintain smooth acceleration and deceleration while driving.
Distracted driving remains one of the most persistent risks in fleet operations. New approaches focus on removing mobile device use entirely while adding real-time safety support.
As distraction risks evolve, fleets are turning to smarter, more connected technologies to better understand what’s happening behind the wheel. Part 2 explores how these tools are helping identify risky behaviors and improve visibility across operations.
Distracted driving is often measured by what we can see—phones in hand, eyes off the road. But what about the distractions we can’t? A recent incident raises a bigger question about awareness, attention, and why subtle risks so often go unnoticed.
Fleets have more driver data than ever, so why isn't behavior changing? Training requires more than reports and coaching — it requires real-world practice.
A two-part conversation with Stefan Heck on how AI is transforming the fight against distracted driving. As fleets adopt smarter tools, the focus shifts from reacting to preventing risk. In Part 1, we look at where AI is making an impact for fleets today.
An 11% drop in pedestrian fatalities in early 2025 signals progress in U.S. road safety, but elevated death rates and ongoing risks underscore the need for continued action from fleets and policymakers.
