Integrating Leading-Edge Safety Technologies Aiming to Make Vehicles Less Likely to Be Involved in an Accident
Toyota technology aiming to minimize risk at every driving stage
Toyota’s Integrated Safety Management Concept, which is rooted in our technological development,
should not be thought of as a collection of independent safety systems installed in a vehicle. Rather, the
goal is to link each of these systems to enhance overall effectiveness. Not only the conventional safety
technology area which is focused on the sequence just before and after the accident, we are focusing to
provide optimal support at every driving stage, from being parked through normal driving, pre-crash, post-
crash to the arrival of rescue. We are developing active safety, pre-crash safety, passive safety and rescue
technologies with the goal of producing vehicles that support the driver in avoiding dangerous situations.
Development of the pre-crash safety system
When the pre-crash safety system detects an
obstruction and determines the possibility of collision,
it notifies the driver with a warning buzzer. Then the
pre-crash brake assist is activated and increases the
braking force when the driver hits the brake. By
accident avoidance maneuverability through
extended nighttime sensor range and the integration
control of breaking and steering, we are seeking to
develop pre-crash safety system which helps to
avoid collision as well as reduce collision damage
via a “collision avoidance support system.”
Emergency-response technology
We are developing technologies that predict danger
prior to emergencies caused by the driver losing
consciousness, such steering wheels equipped with
cardiovascular monitors that check for abnormalities
while the steering wheel is gripped. In the future, we
aim to commercialize systems that can assist daily
health maintenance.
Variable light distribution headlamps (ADB)
We are developing an ADB system that aims to retain
night time visibility nearly equivalent to high-beam
illumination while high-beam light from ADB-fitted
vehicle is partially shielded by ECV automatically to
prevent glare that can interfere with the visibility of
drivers of vehicles ahead.
VSC (Vehicle Stability Control)
When this driver support system senses a loss of
traction or a slip during cornering or on a slippery
road, braking is automatically applied to all four
individual wheels and engine power is reduced.
Wrong way driving alert for navigation systems
Drivers unaware that they are on the wrong side of
the road can cause serious highway accidents. Our
navigation system sense when the car is traveling
against traffic and alert the driver.

These systems offer transmission between the road
and the vehicle, or between vehicles, to help drivers
prevent accidents. (ITS Spot Service (DSRC) vehicle
infrastructure integration systems, etc.)

Vehicle bodies which help to mitigate pedestrian injury
Toyota began manufacturing vehicle bodies that help mitigate pedestrian injury in 2001 and has been
expanding their use. Also, we are developing a pop-up hood that even applies to vehicles with low hoods
that cannot maintain sufficient space underneath by which bumper sensors will detect a collision with a
pedestrian, automatically lifting the back section of the hood to expand the space under the hood. This
contributes to a reduction of head injuries to the pedestrians.

Pre-crash safety technologies Rescue-related technologies
Passive safety technologies
VDIM (Vehicle Dynamics Integrated Management)
The goal of the VDIM is to provide stability of the
vehicle based on vehicle performance control
technology. Great passive safety and ideal maneu-
verability plus driving stability are fundamental
elements of success. The VDIM effectively aims to
reduce the possibility of an accident by integrating
ABS, TRC, VSC and power steering together as one.
