Vehicle Safety Performance 2024
From Vehicle Safety Performance 2024, new evaluation has been newly introduced into “Autonomous Emergency Braking System”, “Passenger Protection Performance”, and “Pedestrian Protection Performance”.
First, in “Autonomous Emergency Braking System”, it is newly started to evaluate in cases where an on-coming vehicle goes straight through in front of the test vehicle turning right at the intersection and in cases where a pedestrian target crosses the road in front of the test vehicle turning right or left at the intersection.
Next, in “Passenger protection Performance”, in addition to evaluation for protection performance for passengers in test vehicle (Self protection: SP) implemented from before, protection performance for reducing damage to another vehicle (Partner Protection: PP) is newly launched (hereinafter referred to as “New Offset Frontal Collision”). Thus, in order to be highly evaluated at New Offset Frontal Collision Test, it is required to ensure the performance of the PP for another vehicle as well as the SP of the test vehicle.
Lastly, in “Pedestrian Protection Performance”, the evaluation area for “Leg Protection” is enlarged to include a new evaluation part of femur in addition to the existing evaluation for knee and tibia.
The total score of Preventive safety performance, Collision safety performance and Automatic Accident Emergency Call System determines the number of ★. The higher the number of ★, the higher the overall safety performance (Overall evaluation). The Overall evaluation ranges 5 levels of stars from ★★★★★ to ★.
The total score of the Preventive safety performance (out of 85.8 points), the Collision safety performance (out of 100 points) and the Automatic accident emergency call system (out of 8 points) is 193.8 points.
Due to changes in the evaluation contents, the allocation of points has been changed. Therefore, it is not possible to make direct comparisons of safety performances based on their scores with vehicle models evaluated in the past.
To earn ★★★★★, a vehicle must have the highest ranking (A rank) in both of Collision safety performance and Preventive safety performance, and must be equipped with an Automatic accident emergency call system.
Taking account of the traffic accident occurrence situation in Japan and the damage reduction effects of equipment and functions, the allocation of points for each evaluation item is determined.
