Navigation in vehicle crash test using MEMS-based IMU

There is a stark disparity in motor vehicle crash deaths and injuries between male and female drivers. Female drivers are 13% more likely to be killed than their male counterparts in similar motor accidents. However, vehicle safety test practices do not account for diverse body proportions when assessing safety outcomes. Vehicle crash testing standards only require testing of two variations of adult-sized crash test dummies: a 50th percentile male and a 5th percentile female. Automotive companies are not required to test safety outcomes in crash test model’s representative of average female proportions or of non-average body sizes and physiological compositions. Current crash test standards are regulated by the National Highway Traffic Safety Administration (NHTSA) under the US Department of Transportation. This memo proposes three actions for the NHTSA and the Department of Transportation to address disparities in vehicle safety outcomes: 1) update safety standard requirements to include a 50th percentile female crash test dummy, 2) implement a federal tax incentive program for companies to include a greater diversity of vehicle occupant models, and 3) allocate funds for research and development of virtual crash testing models. These proposed initiatives seek to raise the minimum safety requirements and prioritize wider representation of vehicle occupants to improve parity in vehicle safety outcomes.

Vehicle crash test is considered to be the most direct and common approach to assess the vehicle crashworthiness. However, it suffers from the drawbacks of high experiment cost and huge time consumption. Therefore, the establishment of a mathematical model of vehicle crash which can simplify the analysis process is significantly attractive. In this paper, we present the application of LPV-ARMAX model to simulate the car-to-pole collision with different initial impact velocities. The parameters of the LPV-ARMAX are assumed to have dependence on the initial impact velocities. Instead of establishing a set of LTI models for vehicle crashes with various impact velocities, the LPV-ARMAX model is comparatively simple and applicable to predict the responses of new collision situations different from the ones used for identification. Finally, the comparison between the predicted response and the real test data is conducted, which shows the high fidelity of the LPV-ARMAX model.

A finite element (FE) model of a baseline and a light-weighted 2007 Chevrolet Silverado, which is a body-on-frame pickup truck, was utilized to evaluate the safety performance of a plastics and composite intensive vehicle (PCIV). By lightweighting steel components in the Silverado using advanced plastics and composites, the original vehicle weight, 2,307 kg, was reduced to 1,874 kg, which is about a 19.0% decrease. As a result, the light-weighted vehicle contains about 442 kg of plastic and composites, which represents about 23.6% of the total weight of the light-weight vehicle. These light-weighted components includes not only non-structural components, but also structural and semi-structural components, such as the bumpers, front-end modules, fenders, door impact beams, A- and B-pillar reinforcements, and ladder frame. The crash performance of these structural components was evaluated by the simulations of four vehicle crash tests: (1) frontal New Car Assessment Program (NCAP) test, (2) frontal Insurance Institute for Highway Safety (IIHS) offset test, (3) side NCAP test, and (4) Federal Motor Vehicle Safety Standards (FMVSS) 216 roof test. The results show that structural composite components in a vehicle are able to provide equivalent crashworthiness performance to the steel components in frontal and side crash and roof testing configurations.
