Publication number: 20210097219Abstract: An apparatus and a method optimize a restraint specification based on a particle swarm optimization algorithm using impact analysis between the restraint specification and passenger injuries. A passenger injury prediction value is generated according to the injury degree of a passenger by sequentially inputting values according to specifications of each design variable included in the injury result data into a particle swarm optimization algorithm. The optimization algorithm is implemented with a plurality of computational layers formed for each detailed configuration in order to search for an optimal specification of a restraint. Information on the optimal specification of the restraint is provided by calculating a comprehensive result indicator using the passenger injury prediction value. Thus, the information on the optimal specification of the restraint can be calculated without repetitive evaluation tests.Type: ApplicationFiled: July 16, 2020Publication date: April 1, 2021Applicants: HYUNDAI MOTOR COMPANY, KIA MOTORS CORPORATIONInventors: Jong Hun Choi, Hong Jung Kim, Seung Kyu Kang
