Safety Performance at Side Collision

Test method


As a type of collision to cause injury to occupants in vehicles, in the extent of injury the side collision is second to the frontal collision. Here a truck imitating a vehicle (its frontal collision portion is provided with an impact absorbing portion imitating the front of the vehicle) hit the test vehicle standing still with the dummy placed in the driver's seat at a speed of 55km/h, 10% higher than that for the collision test of the Safety Standards (increase of 21% in kinetic energy), and the degree of impact to the dummy's head, chest, abdomen, and waist was measured and the vehicle's damage and deformation were investigated. The results of the impact tests are evaluated in 5 ranks, A through E, depending on whether the degree of impact against 4 portions, the head, chest, abdomen, and waist, meets the reference value of each injury, and is attached to data especially good among rank A.


Actually, various accidents occur, and if the seat belt is not worn, the impact speed is very fast, or the counterpart truck is large, the test results obtained this time do not apply.

In the safety performance test for side collision, a dummy called Euro SID-1 imitating a human body is installed.This dummy was developed in Europe imitating an average male adult.It's height is 178cm and its weight is about 75kg.
