Abstract Logistic regression analysis for accident cases of NASS-PCDS (National Automotive Sampling System-Pedestrian Crash Data Study) clearly shows that the extent and the degree of pedestrian's lower extremity injury depend on various factors such as the impact speed, the ratio of the pedestrian height to that of the bonnet leading edge (BLE) of the striking vehicle, bumper to knee ratio, bumper lead angle, age of the pedestrian, and posture of the pedestrian at the time of impact. The pedestrian population is divided in 3 groups, equivalent to small-shorter, medium-height and large-taller pedestrian with respect to the “pedestrian to BLE height-ratio” in order to quantify the degree of influence of lower leg injuries in each group. Large adult male finite element model (95th percentile male: 190 cm and 103 kg) was developed by morphing the Japan Automobile Manufacturers Association (JAMA) 50th percentile male.

Abstract This paper describes the development of high efficiency and compact bumper recycling equipment for facilitating bumper recycling globally. Various equipment to remove paint coat from bumper has been developed since 90s', using mechanical, physical or chemical method. However, it is difficult to promote bumper recycling without realizing cost effective overall system from paint coat removal to pelletizing. Our company jointly developed method of mechanically removing paint coat and has committed to bumper recycling in the form of outsourcing since 2000. In 2010, a dedicated plant for recycling bumpers was launched on the premises of our Oppama Assembly Plant in Japan. In the future, promoting bumper recycling at other overseas assembly plants is necessary as vehicle production will expand globally.

This paper describes the performance evolution and key breakthroughs of the world's first one-motor two-clutch (1M2CL) parallel full hybrid system without a torque converter that was developed and implemented on a hybrid luxury sedan in November 2010. The high potential of this hybrid system was brought out further to improve fuel economy without sacrificing acceleration performance. The resultant second generation of the 1M2CL parallel full hybrid system was applied to a hybrid premium sports sedan in August 2013. In order to improve these performance attributes, the following key technical measures were adopted: 1 Motor torque during the EV mode was increased to expand the EV drive region.2 Maximum motor torque and battery power at engine startup were boosted to reduce the engine start time.3 Integrated control of the motor and clutches was improved.4 Mechanical efficiencies were improved for higher fuel economy.

Abstract A logistic regression analysis of accident cases in the NASS-PCDS (National Automotive Sampling System-Pedestrian Crash Data Study) database clearly shows that pedestrian pelvis injuries tend to be complex and depend on various factors such as the impact speed, the ratio of the pedestrian height to that of the bonnet leading edge (BLE) of the striking vehicle, and the gender and age of the pedestrian. Adult female models (50th %ile female AF50: 161 cm and 61 kg; 5th %ile female AF05: 154 cm and 50 kg) were developed by morphing the JAMA 50th %ile male AM50 and substituting the pelvis of the GHBMC AM50 model. The fine-meshed pelvis model thus obtained is capable of predicting pelvis fractures. Simulations conducted with these models indicate that the characteristics of pelvis injury patterns in male and female pedestrians are influenced by the hip/BLE height ratio and to some extent by the pelvis bone shape.

Abstract A comprehensive analysis was performed to evaluate the effect of BMI on different body region injuries for side impact. The accident data for this study was taken from the National Automotive Sampling System-Crashworthiness Data System (NASS-CDS). It was found that the mean BMI values for driver and front passengers increases over the years in the US. To study the effect of BMI, the range was divided into three groups: Thin (BMI<21), Normal (BMI 24-27) and Obese (BMI>30). Other important variables considered for this study were model year (MY1995-99 for old vehicles & MY2000-08 for newer vehicles), impact location (side-front F, side-center P & side-distributed Y) and direction of force (8-10 o'clock for nearside & 2-4 o'clock for far-side). Accident cases involving older occupants above 60 years was omitted in order to minimize the bone strength depreciation effect. Results of the present study indicated that the Model Year has influence on lower extremity injuries.

Abstract This paper presents a study of a cooled exhaust gas recirculation (EGR) system applied to a turbocharged gasoline engine for improving fuel economy. The use of a higher compression ratio and further engine downsizing have been examined in recent years as ways of improving the fuel efficiency of turbocharged gasoline engines. It is particularly important to improve fuel economy under high load conditions, especially in the turbocharged region. The key points for improving fuel economy in this region are to suppress knocking, reduce the exhaust temperature and increase the specific heat ratio. There are several varieties of cooled EGR systems such as low-pressure loop EGR (LP-EGR), high-pressure loop EGR (HP-EGR) and other systems. The LP-EGR system was chosen for the following reasons. It is possible to supply sufficient EGR under a comparatively highly turbocharged condition at low engine speed.
