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, base 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 ?ve


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 technical regulations. In the case of offset frontal collision which does not have domestic standard, it is equivalent to the European technical regulations.(The same can be said for the individual test evaluation.)

Individual test evaluations

Points for the driver's seat, front passenger's seat and rear passenger's seat 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 6 points out of 12 is given level 1 and the rest of the range is divided up into equal parts, which are respectively assigned to level 2 (more than 6 points but 7.5 or less), level 3 (more than 7.5 points but 9 or less), level 4 (more than 9 points but 10.5 or less) or level 5 (more than 10.5 points).

Neck injury protection for rear-end collision performance evaluation

Four-color coding and points out of 12 are shown according to the driver's seat and front passenger's seat. Furthermore, in order to accurately differentiate between the evaluations of different vehicles, a standard of neck injury protection for rear-end collision performance is set based on current commercially-available vehicles. Orange represents up to 5 points out of 12 and the rest of the range is divided into three parts; yellow (more than 5 points but 8 or less), light green (more than 8 points but 10 or less) and green (more than 10 points).

"Neck injury protection for rear-end collision performance evaluation" injury risks by color

Each color represents an estimated probability of serious neck injury at a residual disability level (WAD2+risk).
In this probability, a standard of neck injury protection performance for rear-end collision is set based on current commercially-available vehicles.
Orange (5 points or less) represents 89% or higher, yellow (more than 5 points but 8 or less) represents 66 to 89%, light green (more than 8 points but 10 or less) represents 44 to 66% and green (more than 10 points) represents 15 to 44%.
Please note that this injury probability is calculated on the basis of injury values when the Dealta V is 17.6km/h (reproduction of collision shocks when a car crushes into a parked car which is the same in mass at a rate of around 32km/h) and the passengers are seated normally and may be different from actual rear-end collision accidents due to differences in collision speed, mass, passenger's posture/physical size and seat's adjustment position.

Determining side curtain air bag evaluation and displaying the results of the test

From FY2008, the side curtain air bag deployment check was added to the side collision test.
