Jakarta merupakan salah satu kota megapolitan yang mempunyai jumlah angka kepadatan penduduk yang sangat tinggi. Tingginya angka kepadatan penduduk di Jakarta membuat laju pertumbuhan pengguna kendaraan bermotor menjadi sangat besar yang menimbulkan kemacetan. Kemacetan yang sering melanda Jakarta membuat masyarakat berganti untuk menggunakan moda transportasi lain yaitu KRL (Kereta Rel Listrik) yang diyakini masyarakat Jakarta sebagai moda transportasi yang aman, murah, dan cepat. Namun, seiring berjalannya waktu minimnya pengembangan teknologi pada transportasi KRL menyebabkan terjadinya beberapa kasus kecelakaan tabrakan pada kereta rel listrik. Banyak faktor yang mempengaruhi tingkat kecelakaan tabrakan seperti sistem komunikasi yang kurang baik, human error, dan pengguna kendaraan bermotor yang tidak tertib saat melintas palang pintu perlintasan kereta. Hal tersebut membuat tingkat keselamatan para pengguna moda transportasi KRL menjadi menurun. Pada penelitian ini, teknologi AEB yang sering digunakan pada mobil akan diaplikasikan penerapannya pada sistem pengaturan rem otomatis yang terintegrasi pada kereta api. Didukung melalui inovasi teknologi ini yang mengusung metode sistem otomatisasi (Automation System) berupa sistem pengaturan rem otomatis yang saling terintegrasi menggunakan sistem berbasis Embedded System pada sensor ultrasonik yang berfungsi untuk mendeteksi jarak obyek yang melintas di depan rangkaian kereta rel listrik. Data yang dikirimkan oleh sensor akan diproses oleh kontroler untuk mengkalkulasi jarak obyek dari sensor yang berguna untuk pengaturan rem otomatis. Sehingga diharapkan AEB dapat menjadi sebuah solusi untuk membantu meminimalisir tingkat kecelakaan tabrakan pada KRL (Kereta Rel Listrik).

Driver Error

The factor of driver error in driving (human error) is one of the causes of the high number of traffic accidents in the present. To anticipate this, the discipline and concentration of the driver when driving is needed. However, when drivers have discipline and sufficient concentration of accidents can still occur. Therefore, the quality of the vehicle security system also greatly affects safety when driving. With the development of science and technology today it is very possible for humans to make security systems in vehicles. Accidents are often caused by the driver being unable to react quickly when there is a sudden blocking of objects. Especially when the driver is driving at high speed. This can be overcome by automating the braking system, so that the vehicle's speed will slow down even though the driver does not step on the brake lever. So that the possibility of an accident can be avoided. And automation is expected to be implemented in vehicles widely. In this study, designed a brake automation system using fuzzy logic by making a prototype. This prototype serves as a visual aid to evaluate the workings of the membership functions that will be used. From this evaluation it is known the value of each membership function. These values ​​are used as the main parameters in determining the Rules that will affect the output value of the brake force. With these Rules, automation of the brake system can work optimally. And it is known that the distance of the prototype car can run between other obstacle with a width of 50cm and the braking of the prototype car stops completely when the prototype is ± 5-10 cm with the obstacle in front of it. Keywords: Automation of Brake Systems, Fuzzy Logic, Distance, Speed.

This work is based on Design of a transport line conveyor belt for sorting and arranging products based on their height using the IR sensors for detecting the object and mechanism to drive the conveyor belt. The project is locally controlled by the use of Arduino based embedded system. The automatic sorting and arranging machine are used to sort the different types of products based on the product height. This automation significantly reduces the time required for manual sorting in the production line of small/medium scale industries and hence it also decreases the percentage of human error during sorting/arranging. The products are placed on the transport line conveyor system and as it moves on the conveyor it is scanned by the IR sensor, depending on the height of the product these will be sorted into different bins automatically.

The inclined lifts, in case of emergency braking, can experience high longitudinal decelerations that can lead to passengers’ collisions with lift walls and interior elements. In 2014 the CEN/TC10 WG1 published the part 22 of the norm series 81 with regard to the construction elements and installation of electrical lifts with inclined trajectory. This norm stablishes, amongst other requirements, the maximum and minimum deceleration levels in both longitudinal and vertical directions. Both requirements, in opposite senses and the definition of the braking system, do not cause design difficulties in case of high slopes, but in case of lifts with the slope under a certain level they can be needed, to guarantee the fulfilment of the norm, elements that allow and additional relative displacement between the braking system and the cabin. To define the performances and the optimal behaviour of these systems it has been defined a simulation model of the dynamical behaviour of the lift under the conditions of the norm tests. Additionally, in this work it is presented a calculation methodology to define the cabin allowable weight corridor, for each braking effort made by each safety gear model, and the simulations have been validated with the results of tests with different braking efforts, weights and lift slopes. The present work has been performed in cooperation with Thyssen Krupp Elevadores with the aim of improving the knowledge of the brake dynamics of inclined lifts.DOI: http://dx.doi.org/10.4995/CIT2016.2016.2173

Abstract Among the many elements of a modern vehicle, the braking system is definitely among the most important ones. Health, and, frequently, life, may rest upon the design and reliability of brakes. The most common friction pair used in passenger cars today is a disc which rotates with the road wheel and a cooperating pair of brake pads. The composite material of the pad results in changing tribological properties as the pad wears, which was demonstrated in experimental studies. The change is also facilitated by the harsh operating conditions of brakes (high and rapid temperature changes, water, etc.). This paper looks into how changing tribology reflects on the heating process of disc and pads during braking. And so a simulation study was conducted, as this method makes it possible to measure temperature in any given point and at any time, which is either impossible or extremely difficult in real life conditions. Finite element method analyses were performed for emergency braking events at various initial speeds of the vehicle reflecting the current road speed limits.

The article describes the main development and testing aspects of an emergency braking function for an autonomous vehicle. The purpose of this function is to prevent the vehicle from collisions with obstacles, either stationary or moving. An algorithm is proposed to calculate deceleration for the automated braking, which takes into account the distance to the obstacle and velocities of both the vehicle and the obstacle. In addition, the algorithm adapts to deviations from the required deceleration, which are inevitable in the real-world practice due to external and internal disturbances and unaccounted dynamics of the vehicle and its systems. The algorithm was implemented as a part of the vehicle’s mathematical model. Simulations were conducted, which allowed to verify algorithm’s operability and tentatively select the system parameters providing satisfactory braking performance of the vehicle. The braking function elaborated by means of modeling then was connected to the solenoid braking controller of the experimental autonomous vehicle using a real-time prototyping technology. In order to estimate operability and calibrate parameters of the function, outdoor experiments were conducted at a test track. A good consistency was observed between the test results and simulation results. The test results have proven correct operation of the emergency braking function, acceptable braking performance of the vehicle provided by this function, and its capability of preventing collisions.
