With the development of the automobile industry,the ultimate goal of automobile from"zero death"to"zero casualties"and then to"zero accidents"continues to move forward,and the safety of automobiles,especially collision safety,has attracted more and more attention.Compared with C-NCAP 2018 version,knee mapping test of instrument panel 2021 version adopts front 50％overlap moving progressive deformation barrier crash test(MPDB)to replace front 40％overlap deformable barrier crash test,and introduces the scoring requirements of variable area contact and concentrated force load as well as the test prerequisite to achieve rules.Based on the interpretation of C-NCAP knee touch scoring procedures for 2021 edition,this paper explores and proposes a dashboard design method to achieve five-star knee-mapping.
