Lexus announced it will begin progressively rolling out the second-generation of its Lexus Safety System +, which is enhanced from the set of active safety packages first introduced in 2015, in its lineup from 2018, primarily in Japan, North America, and Europe.

Lexus Safety System + is a set of active safety packages developed to reduce accidents guided by the concept of supporting drivers under the assumption that they will drive safely, while mitigating damage should an accident occur. It comprises several functions, and its key features include the following:

• Pre-Collision System (PCS), which helps prevent and mitigate collisions with preceding vehicles or pedestrians
• Lane Departure Alert (LDA), which helps prevent vehicles from departing their lanes
• Automatic High Beam (AHB), which helps ensure optimal forward visibility during nighttime driving

Lexus will roll out the pre-collision support of Lexus Safety System + A, an advanced active safety package installed in the new LS, and some functions of its Lexus CoDrive advanced driving support in the second generation Lexus Safety System +. It will continue to use the single-lens camera and millimeter-wave radar currently employed in the first-generation Lexus Safety System +. It will be further enhanced with the following: It will feature expanded scope of hazard detection, and improved functionality via enhancements such as improvements to the performance of the camera and radar. It will include the advanced driving support feature Lane Tracing Assist (LTA). In addition, the number of Lexus CoDrive cars will be increased, and the size of the unit will be reduced to improve ease of installation.

Expanded scope of hazard detection and improved functionality will be accomplished by the following:

• Adding nighttime pedestrians and cyclists to the scope of hazards detected by PCS.
• The current system is unable to detect nighttime pedestrians and cyclists. Adding these to the scope further broadens protection from causes of severe accidents.
• Road Sign Assist (RSA)
• Key road signs are read by the camera and displayed in the instrument panel.
• This feature supports even safer driving by helping to reduce the possibility of overlooking speed limits and traffic rules, such as stop signs, no entry signs, and no overtaking signs.

Advanced driving support Lexus CoDrive:

• Lane Tracing Assist (LTA) has been adopted to achieve such aims as reducing driver burden and improving convenience.
• It keeps the vehicle in the center of a lane by assisting the driver in steering control when using Dynamic Radar Cruise Control. By including features such as Dynamic Radar Cruise Control, driver burden can be reduced in locations such as expressways, allowing drivers to drive with greater ease.
• LTA also comes with Lane Departure Alert (LDA). With the ability to recognize shoulders on straight roads without white lane markings, it gives alerts (display, buzzer, or steering vibration) when deviating off roads, and assists in regaining track.

The rollout (either as a standard or optional configuration) of the first-generation Lexus Safety System + in most Lexus cars in Japan, North America, and Europe has recently been completed.
