"The book provides the essential features necessary to understand and apply the mathematical-mechanical characteristics and tools for vehicle dynamics including control mechanism. An introduction to passenger car modeling of different complexities provides the basics for the dynamical behavior and presents vehicle models later used for the application of control strategies. The presented modeling of the tire behavior, also for transient changes of the contact patch properties, shows the necessary mathematical descriptions used for the simulation of the vehicle dynamics. The introduction to control for cars and its extension to complex applications using e.g. observers and state estimators is a main part of the book. Finally the formulation of proper multibody codes for the simulation leads to the integration of all parts. Examples of simulations and corresponding test verifications show the profit of such a theoretical support for the investigation of the dynamics of passenger cars."

"ABSTRAK
Selama beberapa dekade, trasportasi digunakan untuk memindahkan orang atau barang dari titik A ke B. Ada beberapa jenis transportasi yang digunakan hingga sekarang, dan salah satunya adalah mobil. Kendaraan ini adalah salah satu yang paling populer karena simple, efisien, dan cukup untuk berpergian dengan jarak yang jauh. Angka populasi mobil terus meningkat setaip tahunya sehingga tidak ada ruang yang cukup untuk bias menampung banyaknya mobil dengan situasi jalanan yang sudah ada, dan dari masalah itu meciptakan kemacetan. Kendaraan mobil ini terus berkembang setiap tahunya dan selalu menambahkan fitur serta teknologi yang terbaru yang membuat pengunanya merasa lebih nyaman, tetapi tidak memecahkan masalah kemacetan, kecuali mobil ini bias terbang. Mengkaitkan ilmu kerdirgantaraan dan otomotif adalah ruang yang cukup besar untuk di satukan, dan memiliki keterbatasan, tetapi tidak menutup kemungkinan untuk membuat mobil terbang. Mekanisme pelipatan bias digunakan sebelum mobil terbang bias digunakan di jalanan umum. Stuktur dasar sepanjang 4m dari sayap mobil terbang dibagi menjadi tiga bagian yang berbeda untuk mencapai posisi terakhir pelipatan di bodi mobil. Total berat mekanisme pelipatan sayap beserta struktur dasar sayap dengan material AL707T6 adalah 53,11 kg dan berat kosong pada bodi adalah 700kg.
ABSTRACT
Over the decades, transportation was used in order to move a person or an object from point A to B. There are few types of transportation has been used until now, one of them is Car. Is one of the most popular transportation because is simple, efficient, and enough to travel with distance. Over the year the number of cars is keep increasing, according to the population of car, there is no more room on the road to line up the car while driving and simply create a traffic jam. By the time goes, the car itself is keep improving with new technology and features that makes the user more comfortable while riding it, but it does not solve the traffic jam problem unless the car is flying. Involving the aerospace engineering into the automotive industry is one big gap and has many limitations, but it does not rule out the possibility to make a flying car. The mechanism can be used to fold the wing before the car is used on the regular street. The basic wing structure with 4m length has been divided into three different section in order to achieve a final position on the fuselage. The total weight of folding mechanism including the basic wing structure using AL707T6 material is 53,11kg and the empty weight of the fuselage is 700kg."

"Autonomous car atau kendaraan tanpa awak merupakan salah satu bagian dari sistem transportasi cerdas yang kelak akan digunakan. Kendaraan tanpa awak memungkinkan kendaraan dapat bergerak dan mengontrol dirinya secara mandiri tanpa bantuan manusia. Salah satu fitur yang paling penting pada kendaraan tanpa awak adalah sistem navigasi. Beragam sistem navigasi yang sudah berkembang ialah metode SLAM dengan LiDAR, penggunaan odometer, ataupun dengan sensor GPS dan gyroscope. Namun, metode-metode tersebut masih perlu pengaturan ulang (tuning) dan penentuan trajectory yang masih dilakukan manual. Oleh karena itu, perlu dilakukan pengembangan sehingga sistem navigasi kendaraan otonomus yang terhubung dengan sistem pemetaan. Pada penelitian ini, diujicobakan sebuah sistem yang mengintegrasikan antara GPS, Google Maps, dan sensor vision sehingga kendaraan dapat berjalan sesuai dengan trajectory yang mudah diatur. Sensor GPS dan Google Maps akan bekekerja sama untuk melakukan mapping lokasi dan mengatur tujuan perjalanan. Sedangkan sensor vision yang menggunakan kamera akan berfungsi sebagai pengatur kesesuaian jalan dengan marka jalan. Hasil penelitian ini didapatkan bahwa keberhasilan pendeteksian jalan mencapai 93,37 %, ketepatan Google Maps dalam mengenali jalan 97,54 % dengan rata-rata kecepata 0,2205 detik, serta kecepatan pemrosesan pembuatan trajectory adalah 0,155 detik.

Autonomous cars or unmanned vehicles are one part of the intelligent transportation system that will be used in the future. Unmanned vehicles allow vehicles to move and control themselves independently without human assistance. One of the most important features of unmanned vehicles is the navigation system. Various navigation systems that have been developed are the SLAM method with LiDAR, the use of an odometer, or GPS and gyroscope sensors. However, these methods still need tuning and trajectory determination is still done manually. Therefore, it is necessary to develop an autonomous vehicle navigation system that is connected to the mapping system. In this research, a system that integrates GPS, Google Maps, and vision sensors is tested so that the vehicle can run according to a manageable trajectory. GPS sensors and Google Maps will work together to map locations and set travel destinations. While the vision sensor that uses a camera will function as a regulator of road conformity with road markings. The results of this study found that the success of road detection reached 93.37%, the accuracy of Google Maps in recognizing roads was 97.54% with an average speed of 0.2205 seconds, and the processing speed of making trajectories was 0.155 seconds."

"ABSTRAK
Teknik yang digunakan untuk Sistem Pemantau Lalu Lintas pada masa sekarang
ini banyak tergantung pada sensor-sensor yang mempunyai kemampuan yang
terbatas, kurang fleksibel, dan seringkali mahal dan sulit untuk dipasang.
Penggunaan kamera digabungkan dengan teknologi Computer Vision menjadi
alternatif yang menarik dari sensor yang ada saat ini. Sensor berbasis kamera ini
mempunyai potensi yang lebih besar untuk mengamati kondisi lalu lintas yang
ada dibanding sensor konvensional saat ini yaitu sensor ini lebih murah dan
mudah untuk dipasang.Di dalam penelitian ini dikembangkan sistem pemantau
lalu lintas menggunakan metode Optical Flow dan Gaussian Mixture Model.
Eksperimen dilakukan menggunakan handycam, berlokasi di salah satu tol dalam
kota Jakarta. Kondisi pengambilan gambar adalah pada kondisi yang berbedabeda
yaitu pada saat pagi, siang, dan sore, cuaca cerah, dan mendung, serta
kondisi arus lalu lintas padat dan lancar. Setelah pengujian dilakukan, algoritma
Optical Flow memberikan hasil yang lebih baik dibandingkan algoritma Gaussian
Mixture Model yaitu dengan akurasi mencapai 92% dibanding Gaussian yang
hanya mencapai 72%. Faktor-faktor yang mempengaruhi tingkat akurasi adalah
kondisi waktu, cuaca, dan arus kendaraan serta lokasi pengambilan gambar.

Abstract
Current techniques for Sistem Pemantau Lalu Lintas rely on sensors which have
limited capabilities, inflexible and often, costly and disruptive to be installed.
Video camera, coupled with Computer Vision techniques offers an attractive
alternative to current sensors which is portable and low cost . In this research, a
traffic monitoring system using handy camera is developed using Optical Flow
and Gaussian Mixture Model (GMM) methods. The experiment took place in one
of the Jakarta city highway. The condition of the experiment is when the time is in
the morning, afternoon, evening, when it is clear, and cloudy, and also when the
traffic is light and heavy. The experiments shows that Optical Flow algorithm
gives better results regarding to accuracy rate, better than Gaussian Mixture
Model Algorithm. The Optical Flow reach 92% accuracy while Gaussian Mixture
only got to 72% accuracy. Some factors that influenced the accuracy rate of the
system are time, weather, traffic and location."
