The evaluation method of a result
| In order to test collision safety performance, we performed a full-wrap frontal
collision test, offset frontal collision test, and a side collision
test. The test vehicles consisted of 21 different models. The
results of these tests are reported using the methods described
below. Points are calculated for each test and an overall rating
is reported by adding up the total. The test vehicles of the brake
performance tests consisted of 19 different models and the results
are shown on pages 35-36. |

Calculating
points for the full-wrap and offset frontal collision test
|
| Injury values are measured on the dummy for the head, neck, chest, and legs.
These values are then converted into a four-point score using
a point-conversion function used for automobile assessment in
the United States and Europe. Vehicle deformation is also measured
and converted in the same manner to a score of 0 to -1. The value
for vehicle deformation is then subtracted from the value for
injuries and the result is multiplied by the weight coefficient
for this type of accident. In this manner, the overall points
are calculated for each body area. These scores are then added
together to get the total, which is then evaluated to one of five
levels. |

Calculating
points for the side collision test
|
| Injury values are measured on the dummy for the head, chest, abdomen and pelvis.
These values are then converted into a four-point score using
a point-conversion function used for automobile assessment in
the United States and Europe. These values are multiplied by the
weight coefficient for this type of accident and the overall points
are calculated for each body area. These scores are then added
together to get the total, which is then evaluated to one of five
levels. |
|
Determining
the overall collision safety performance evaluation
|
| For the driver's seat, the results of the full-wrap frontal collision test,
offset frontal collision test, and side collision test are added
together and evaluated to six different levels.
For the Frontal passenger's seat, the results of the full-wrap
frontal collision test and the side collision test (results
for the driver's or the front passenger's seat are used) are
added together and evaluated to six different levels. |

Overall
evaluation of collision safety performance
|
| The total points for the test results of the full-wrap, offset, and side collision
tests calculated for the driver's seat and the full-wrap and side
collision (driver's or the front passenger's seat results are
used) tests calculated for the front passenger's seat are each
displayed in a bar graph. In addition, in order to accurately
differentiate the evaluations of each vehicle, standard point
values are set based on what vehicles with today's technology
are believed capable of achieving (16 points out of 36 for the
driver's seat and 12 points out of 24 for the front passenger's
seat). Vehicles which score below these standard point values
are given one star and vehicles which have scores which fall between
the standard point value and top point value are awarded two to
six stars, which is calculated by dividing the range from the
standard point value to the top point value into five equal parts. |
| Note: |
The safety performance in the case of
0 points is equivalent to the standard safety performance
in the case of a test involving a collision speed ten percent
greater than that indicated by government safety standards.
In the case of offset frontal collision which does not have
domestic standard, it is equivalent to the European standard.(The
same can be said for the individual test evaluation.) |

| Individual
test evaluations |
| Points for both the driver's seat and front passenger's seats
are shown in a bar graph. Furthermore, in order to accurately
differentiate between the evaluations of different vehicles, a
standard is set based on current technology. Up to six points
out of twelve is given level 1 and the rest of the range is divided
up into our equal parts, which are respectively assigned 2 to
5. |
