Toyota Motor : Lexus Outlines Advanced Active Safety Technologies for All-new 'LS' Fully Redesigned Flagship Combines Safety Systems toward Elimination of Traffic Casualties

Further evolution of performance of Lexus Safety System + technologies

Lexus has further evolved the performance of PCS, LDA and Dynamic Radar Cruise Control in the active safety Lexus Safety System +, which has been featured in a growing number of vehicle models and has been combined with Lexus Safety System + A in the LS.

Pre-Collision System (PCS)

PCS detects pedestrians and vehicles ahead using millimeter-wave radar and a stereo camera and supports collision prevention and damage mitigation with an alert, Pre-collision Brake Assist and Pre-collision Braking. The improved PCS can detect bicyclists and nighttime pedestrians and has improved deceleration performance during automatic braking. For example, it can decelerate the vehicle by as much as 60 km/hour when a pedestrian is detected, thus improving its collision-prevention performance.

Lane Departure Alert (LDA)

LDA helps to prevent lane departures. In addition to detecting road lane lines, it is now also capable of detecting the boundaries between asphalt and such elements as grass, dirt and curbstone through advances in recognition capability. Thus, it can now perform its functions of alerting the driver and operating the steering wheel even on roads that do not have lines.

Dynamic Radar Cruise Control

Outstanding basic recognition performance has been secured with wide-angle detection using newly developed millimeter-wave radar and a camera with a wider forward recognition range. Dynamic Radar Cruise Control also provides support for making driving more comfortable, with smooth acceleration at startup, and during following, departure and acceleration, for a sense of security for occupants, and smooth deceleration in the case of a rapid change in deceleration speed during following.
