Toyota Develops New Pedestrian Safety Technology

-Pre-collision System with Pedestrian-avoidance Steer Assist
-Uses Automatic Steering to Help Avoid Collisions

Toyota City, Japan, Oct. 11, 2013 - Toyota Motor Corporation announces
that it has developed a Pre-collision System (PCS) that uses automatic
steering in addition to increased pre-collision braking force and
automatic braking to help prevent collisions with pedestrians. Toyota
is committed to developing safety technologies that help eliminate
traffic fatalities and injuries involving pedestrians and other
vulnerable road users.

The new PCS with Pedestrian-avoidance Steer Assist can help prevent
collisions in cases where automatic braking alone is not sufficient,
such as when the vehicle is travelling too fast or a pedestrian
suddenly steps into the vehicle's path. An on-board sensor detects
pedestrians and issues a visual alert on the dashboard immediately in
front of the driver if the system determines that there is a risk of
collision. If the likelihood of a collision increases, the system
issues an audio and visual alarm to encourage the driver to take
evasive action, and the increased pre-collision braking force and
automatic braking functions are activated. If the system determines
that a collision cannot be avoided by braking alone and there is
sufficient room for avoidance, steer assist is activated to steer the
vehicle away from the pedestrian.

The number of traffic fatalities in Japan has declined for 12
consecutive years, reaching 4,411 in 2012. However, of that total,
pedestrian fatalities are the most common, accounting for 37.0

Last year, Toyota developed a system that uses increased pre-collision
braking force and automatic braking to help prevent collisions with
pedestrians. The system, which was adopted on the Lexus
"LS", warns the driver when it detects a potential collision
with a pedestrian or obstacle. If the driver does not take action to
avoid the collision, the system activates.

TMC aims to make PCS (Pedestrian-avoidance with no steer assist) more
affordable and roll it out by 2015 on a wider range of vehicles,
before introducing PCS with Pedestrian-avoidance Steer Assist.

Toyota to Launch Advanced Driving Support System Using Automated
Driving Technologies in Mid-2010s

-Safer Highway Driving
-Reduced Environmental Effects and Driver Workload

Advanced Active Safety Research Vehicle
The Advanced Active Safety Research test vehicle, based on the Lexus
"LS", is being used in research at the Toyota Research
Institute of North America in Saline, Michigan.
Toyota City, Japan, October 11, 2013 - Toyota Motor Corporation
announces that it has developed a next-generation advanced driving
support system, Automated Highway Driving Assist (AHDA), which uses
automated driving technologies to support safer highway driving.

AHDA links two automated driving technologies to support safer driving
and reduce driver workload: Cooperative-adaptive Cruise Control, which
wirelessly communicates with preceding vehicles to maintain a safe
distance; and Lane Trace Control, which aids steering to keep the
vehicle on an optimal driving line within the lane.

Toyota recognizes the importance of the driver being in ultimate
control of a vehicle and is therefore aiming to introduce AHDA and
other advanced driving support systems wherethe driver maintains
control and the fun-to-drive aspect of controlling a vehicle is not
compromised. Toyota plans to market the newly developed AHDA in the
mid-2010s and other driving support systems as soon as possible to
provide safe and secure means of transportation.

Ahead of trials on the Shuto Expressway near the Tokyo metropolitan
area starting October 15, Toyota will exhibit AHDA at the 20th
Intelligent Transport Systems World Congress Tokyo 2013, an
international conference for intelligent transport systems (ITS), to
be held from October 14 to 18.

In addition, to enable prompt market introduction of next-generation
driving support systems, Toyota will make use of the cutting-edge
component technologies and know-how acquired through automated driving
research conducted with the advanced active safety research vehicle
unveiled at the 2013 International CES in Nevada, United States in
January this year.

Automated Highway Driving Assist (AHDA)

Cooperative-adaptive Cruise Control
In contrast to standard radar cruise control (which uses
millimeter-wave radar to detect other vehicles), Cooperative-adaptive
Cruise Control uses 700-MHz band vehicle-to-vehicle ITS communications
to transmit acceleration and deceleration data of preceding vehicles
so that following vehicles can adjust their speeds accordingly to
better maintain inter-vehicle distance. By reducing unnecessary
acceleration and deceleration, the system improves fuel efficiency and
helps reduce traffic congestion.

Lane Trace Control
Lane Trace Control, which features completely new Toyota automated
driving technologies, employs high-performance cameras,
millimeter-wave radar and control software to enable an optimal and
smooth driving line at all speeds. The system adjusts the vehicle's
steering angle, driving torque and braking force when necessary to
maintain the optimal line within the lane.

Automated Driving Technologies Research

At the 2013 International CES, Toyota displayed the advanced active
safety research vehicle, a test vehicle for automated driving
technologies that Toyota is researching under its Integrated Safety
Management Concept*. The test vehicle, based on the Lexus
"LS", is being used in research at the Toyota Research
Institute of North America in Saline, Michigan, and is capable of
autonomous driving. It is fitted with forward-looking cameras to
detect traffic signals, as well as front-mounted sensors to detect
vehicles, pedestrians, and obstacles to determine traffic conditions,
such as intersections and merging traffic lanes, in the vehicle's
vicinity. Such research on various elemental technologies is aimed to
help drivers choose the safest routes possible.

Toyota has been researching automated driving technologies since the
second half of the 1990s, and has been conducting public road tests in
the U.S. for a number of years. Within Japan, Toyota has been testing
its next-generation Intelligent Driver-support System on public roads
for approximately two years.

Based on the insights gained from automated driving research, Toyota
aims to provide advanced driving support systems optimized to help
enable safer driving and contribute to realizing the ultimate goal of
any society that values mobility: the elimination of traffic
fatalities and injuries.

In anticipation of the super-aging populations of the future, these
advances will also be used to develop technologies that support senior
drivers with recognition, decision-making and vehicle operation, with
the aim of achieving a mobility society where they can lead fuller
lives. Furthermore, Toyota is working to provide more stable driving
environments that contribute to the alleviation of traffic congestion,
thereby reducing economic loss and CO2 emissions.
