Japan’s Ministry of Land, Infrastructure, Transport and Tourism (MLIT) and National Agency for Automotive Safety & Victims’ Aid (NASVA) announced today the results of the evaluation of the automatic braking systems of 26 kinds of vehicles under the Japan New Car Assessment Program (JNCAP). The vehicles that were given a full score of 40 points are Nissan Skyline, Subaru Levorg/WRX and Toyota Lexus LS. Three vehicles of each of the three companies were ranked in the top ten.
In the test, the automatic braking and lane departure warning functions of vehicles were respectively given a score. For the evaluation of automatic braking functions, a vehicle being tested moved toward another vehicle (a target standing or moving at a speed of 20km/h) at a speed of 10 to 60km/h (approx 6.2 to 37.3mph).
A score was given if a warning or braking system operates and a vehicle running toward the target at a ceratin speed can avoid crashing into it. Also, if the vehicle being tested crashes into the target, a score is given depending on how much the vehicle decelerates.
For the the evaluation of lane departure warning functions, a vehicle being tested was driven at a speed of 60 or 70km/h. A point was given depending on whether its lane departure warning system sets off an alarm when the vehicle crosses a white line. The lower the speed at which an alarm is set off, the higher the score. The full scores of the tests of automatic braking and lane departure warning functions are 32 and 8, respectively. The total score can be up to 40.
The scores of the 26 vehicles are as follows.
