최근에 스포츠유틸리티 차량이 점차 대중화되고 있다. 이것은 과거의 단순한 승용차 중심의 자동차 소비구조에서 보다 다양화 된 생활양식에 따라 보다 전문화 된 성능의 차량에 대한 수요가 늘어난 이유에서 인 것으로 보인다. 이러한 수요변화는 주 5일 근무에 의한 여가시간의 증가와 생활수준 향상에 따른 레저활동의 요구 증가 등도 원인이지만, 차량 자체의 성능향상과 차종 다양화 역시 중요한 요인으로 작용하고 있다. 자동차 발전의 역사 초기부터 다양한 유형의 다목적 차량들이 개발되고 사용되어오고 여는데, 이들은 미국의 $\ulcorner$지프$\lrcorner$에서 발전된 차량이 주류를 이루고 있다. 이 차량들은 여러 메이커들을 통해 각각의 기능적 전문성을 살린 다양한 정통적 유형과 복합개념의 차량들로 개발되고 있다. 복합개념의 차량들은 전반적으로 소형화를 추구하는 반면, 정통적 형태의 4륜 구동차량들은 대형화 및 고성능화 되는 양방향의 경향이 동시에 나타나고 있다. 향후에 이러한 경향은 다양한 메이커와 차종에서 확대되어 나타나게 될 것으로 예측된다.

When two cars impact each other, it is usually known smaller vehicle's passenger likely to be more seriously injured than bigger one's. Generally it is known that SUVs and Light Truck Vehicles (LTVs) are bigger and heavier than passenger vehicles and their drive height such as bumper rail and side member, and front end stiffness are higher than those of passenger vehicles. Because of these characteristics the occupants of passenger vehicle struck by SUVs or LTVs are more likely to experience severe injury or fatal injury. To evaluate SUV and LTV's aggressivity to passenger vehicle, SUV to passenger vehicle and LTV to passenger vehicle head-on crash test have been carried out. And finally the way how to reduce incompatibility between SUV and LTV and passenger vehicles is suggested.

Since 2000, sports utility vehicles(SUVs) occupy about 40% of domestic vehicle sales. As sports utility vehicle sales are increased the probability of crash accident between SUVs and passenger vehicles increases. Generally, SUVs are heavier than passenger vehicles and their drive height and front end stillness are higher than passenger vehicles. Because of these characteristics SUVs cause more severe injury and fatal injury in SUV to passenger vehicle head-on impact. To evaluate SUV's aggessivity to passenger vehicle, we carried out SUV to passenger vehicle head-on crash test. And finally the way how to reduce incompatibility between SUVs and passenger vehicles is suggested.

It is a frequent occurrence in urban traffic - a low-speed collision in which one vehicle hits the back of another. The vehicles often sustain expensive damage. Bumpers can reduce this damage, but only line up so the initial contact in an impact is bumper to bumper. Then the bumpers on the colliding vehicles have to absorb the crash energy, keeping damage away from expensive sheet metal, lights, and other components. In real world accidents, Bumper mismatches in crashes are increasing, and the resulting repair costs from low-speed collisions are escalating. In this study, we investigated the bumper rail height and analyzed their effects on repair cost. Futhermore, Our 16kph front-into-rear crash tests demonstrates bumper mismatch problem.

This paper describes an Integrate Dynamic Control system with Brake System (IDCB) for SUV vehicles. The system was developed to stabilize the lateral dynamics, maintain the steerability and improve the ride comfort on various roads. A fuzzy logic control method is used to design the IDCB. The performance of the IDCB is validated under different road and driving conditions. The results show that the IDCB tracks the reference yaw rate under all tested conditions; in addition, it reduces the body slip angle and roll angle. When a vehicle runs on a split-${\mu}$ road and a brake input is applied, the IDCB virtually eliminates the lateral dynamics. Thus, the IDCB improves the lateral stability, preserves the steerability and enhances the ride comfort of vehicles.

The difficulties in opening and closing a sport utility vehicle (SUV) tailgate is important aspect of JD (James David) power's Initial Quality Survey (IQS) assessment, and affective quality has a big impact on the the success of thesedays products. The purpose of this study is to evaluate the perceived difficulty and satisfaction of customers by the opening and closing of the tailgate and to grasp the relationship between them and the opening and closing reaction force. The mechanical force required to open and close 42 domestic and overseas SUV tailgates was measured with the help of an auto company. In the experiment, 100 male drivers in their 20s to 50s evaluated perceived difficulty and satisfaction with opening and closing the tailgate. The results of the analysis showed that perceived difficulty and satisfaction were statistically different depending on the vehicle, but did not depend on the personal characteristics of the participants. The perceived difficulty and satisfaction regression model of tailgate opening and closing was developed by mechanical force variables and had a relatively high adjusted $R^2$ ranging from 0.62 to 0.73. The models showed that the the initial close and open force, the difference between initial and maximum close force and the difference between initial and auto-fall angle should be small for the low perceived exertion and high satisfaction. In addition, the correlation analysis between IQS score of tailages and perceived difficulty and satisfaction showed that the IQS scores were more related to the perceived difficulty and satisfaction of closing than those of opening. The results of the study will be helpful to design and test mechanical open and close structure of SUV tailgates.

2019년 SUV의 경이적인 판매량으로 내수판매 시장에서 세단을 추월하였고 세계 SUV의 강세는 향후 지속적으로 전망한다. 국내 K-기업은 SUV 시장에서 소형 SUV를 공격적으로 출시하면서 선도하고 있는 상황이다. 단순한 라인업으로 SUV의 존재가 아닌 브랜드 이미지로서 그 가치를 인정받고 이를 평가가 필요한 시점이다. 따라서 국내소형 SUV 디자인 이미지 평가를 통해 소형 SUV의 잠재고객과 구매자의 구매의사 결정은 SUV 모델의 기능적 속성 보다는 감성적 특성과 브랜드의 상징성 그리고 이미지에 의해 이루어진다는 점이다. 최종 소비자의 구매 심리에 대한 잠재의식을 은유추출기법을 통해 고객들이 니즈에 맞는 소형 SUV 디자인 이미지 평가 연구를 하고자 하였다. 국내 완성차 소형 SUV 디자인 이미지로 구매의도를 갖거나 구매를 하는 소비자들이 연계성을 갖는 지 알아보고자 하였다. 소비자가 이미지를 느끼며 표현함에서 일차적인 애매모호한 메시지를 잠재된 의식을 은유추출기법인 ZMET을 통해 고객들의 사고와 행동에 영향을 줄 수 있다는 연구의 결론을 추출하였다. 따라서 본 연구 결과를 기반으로 향후 SUV에서 제시되는 이미지가 고객들의 사고와 행동에 영향을 줄 수 있도록 소형 SUV 개발에 있어 디자인 가이드로 활용되었으면 한다.
