Toyota and Lexus roll-out low-cost automated braking safety packages on RAV4 Hybrid and RX crossover

At separate press conferences Wednesday and Thursday at the New York Auto Show, Toyota will reveal the RAV4 Hybrid SUV, while Lexus unveils its all-new fourth-generation RX luxury crossover SUV. Both debuts will mark the arrival of new, multi-feature, integrated safety packages, each anchored by automated pre-collision braking and offered at a price below comparable systems across the auto industry.

Toyota Safety Sense (TSS) and Lexus Safety System+ (LSS+) are designed to support the driver’s awareness, decision making and vehicle operation over a wide range of speeds. Packaged together in an integrated system, their features help address three key areas of accident protection: preventing or mitigating rear collisions; keeping drivers within their lane; and enhancing road safety during night time driving. The systems are intended to address commonly occurring crash types according to traffic accident statistical analyses.

Taking high-level driver assist to the next level, the safety packages will be offered as a very-low-cost option and will be systematically introduced across nearly all US Toyota and Lexus models and trim levels, top-to-bottom, by the end of 2017. Pushing these systems across our lineup, as quickly as possible, can help protect people in the event of a crash. More importantly it will help prevent some crashes from ever happening in the first place.

—Jim Lentz, President and CEO Toyota Motor North America

First announced in Japan this past November, both packages reflect Toyota’s desire to make safety technology available to a wider range of new car buyers.

  • TSS will be offered in the form of two packages: Toyota Safety Sense C for compact cars and TSS P for mid-sized and premium models will be available as an optional accessory from approximately $300 and $500, respectively.

  • Lexus Safety System+ aims to further expand the use of these systems across luxury models, integrating highly-effective active safety features into an optional accessory priced from approximately $500 to $635.

TSS will initially be available on the RAV4 and Avalon, and three additional models which will be announced later this year. LSS+ will initially be available on RX, and four additional models to be announced later this year. Both packages will provide an added layer of safety capability on top of Toyota’s existing Star Safety System, a suite of six key safety technologies that are included as standard on every new vehicle.

Toyota Safety Sense. The Toyota Safety Sense C package features three proprietary active safety technologies, and combines a camera and laser radar for enhanced performance and reliability. The package can help prevent or mitigate collisions in a wide range of vehicle speeds.

  • Pre-collision System (PCS). PCS uses a camera and laser radar to detect objects ahead of the vehicle. When the system determines there is a possibility of collision it prompts the driver to brake with an audio and visual alert. If the driver notices the hazard and brakes, the system provides additional braking force. If the driver fails to brake in a set time, the system automatically applies the brakes, reducing speed by approximately 19 mph (31 km/h) in order to prevent or mitigate the collision. The operational range of PCS covers speeds at which at least 80% of rear-end collisions occur (i.e. relative speeds of between approximately 7 – 50 mph, or 11 - 80 km/h).

  • Lane Departure Alert (LDA). LDA uses a camera to detect visible white and yellow lane markings. If the system determines that the vehicle is starting to deviate from the lane, LDA alerts the driver with an audio and visual alert.

  • Automatic High Beam (AHB). AHB helps enhance 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 so as not to dazzle other drivers.

Toyota Safety Sense P combines a camera and millimeter-wave radar for enhanced performance and reliability. In addition to the three active safety technologies included in the Toyota Safety Sense C package, the Pre-collision System offered with this package also includes a pedestrian detection function. In addition, Toyota Safety Sense P offers Radar Cruise Control functionality.

  • Pedestrian Pre-collision System. This system uses millimeter-wave radar and a camera to help detect pedestrians in certain conditions 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 a set time. Automated braking operates at relative speeds of between 7- 50 mph for potential collisions with pedestrians, and can reduce speed by approximately 19 mph. For potential collisions with vehicles, the enhanced PCS system included with the Toyota Safety Sense P package operates at relative speeds of between 7 mph and the vehicle’s top speed, reducing speed by approximately 25 mph (40 km/h).

  • Dynamic Radar Cruise Control. On highways, Radar Cruise Control uses millimeter-wave radar to detect preceding vehicles and determine their speed. It then is designed to adjust vehicle speed (within a set range) to help maintain a pre-set distance between vehicles. By using a forward-facing camera and millimeter-wave radar to monitor vehicles merging into or out of the lane, Radar Cruise Control helps maintain smooth acceleration and deceleration while driving.

Lexus Safety System +. Lexus Safety System + integrates several of Lexus’s existing active safety technologies: under certain conditions the Pre-Collision System (PCS) helps prevent and mitigate collisions; Lane Departure Alert (LDA) helps prevent vehicles from departing from their lanes; and Automatic High Beam (AHB) helps ensure enhanced 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, achieving high reliability and performance.

Lexus LDA alerts the driver with an audio-visual alert as well as steering wheel vibration. Some models are also equipped with Lane Keep Assist, which controls power steering to help make it easier for the driver to remain within lane markings.

I'm all in favour of it, and just hope that increasing car automation can keep pace with my increasing senility!

That seems doubtful though, but of course I forget why.....

HarveyD

That's good DM.

Since car automation will progress at a high rate during the next 10 years or so, we may have time to see it before senility sets in?

Automatic braking and automated speed limits are good starts.

I was hoping that something could be done in the next ten minutes or so.......

DM: something could be done about what? I forgot the subject.

Speak up young man!
I can't hear you!
