Abstract
Degrees of human intervention for vehicular technology have been decreasing in the past few years. Automated cars and even autonomous ones have been appearing in successive events. One aspect to note is that automated systems for automobiles are believed to follow the technology for electric vehicles. It will then require a real-time control system to guarantee timely responses and task priority setups for internal and external events of real-time systems, especially for the migration of Internal Combustion Engine (ICE) vehicles to electric cars

Abstract
Vehicle generally require an optimal braking system, eddy current brake (ECB) can be used as an alternative to the conventional braking system. Unipolar Axial ECB was discussed in this paper. Performance of ECB is influenced by several factors, like the distance of the pole location to center of the shaft. The pole location determine the braking torque because the change of braking force arm. In this paper, finite element method (FEM) based modeling are used to describe the eddy current change. Size and design of ECB are based on a conventional hydraulic braking system. The standard pole location will be similar to the brake pad on a conventional hydraulic braking system. The pole location will be varied to profile the changes in braking torque. From data, it was found that the pole location near than standard tends to have good braking torque at high speeds. In reverse, at low speeds it has lower braking torque compared to standard pole location. Then at the pole location far than standard give the resulting braking torque is lower in both while low speed and high speed. It is because the eddy current turn path area become narrow on the rotor when the pole location far from standard.

Abstract
Advanced vehicles are an alternative solution to reduce environmental pollution due to the use of fossil fuels. It can be pure electric vehicles or hybrid vehicles. The Hybrid vehicles combine internal combustion engines and electric motors to move. The use of resources on hybrid vehicles can be either series or parallel. A series hybrid model uses an electric motor as a driving force and combustion engine as a generator drive when a parallel hybrid vehicles use both resources as drivers simultaneously. Electrical energy can be obtained from renewable energy or waste utilization. This paper discuss the effectiveness of the use of advanced vehicles to reduce the use of fossil fuels. In this study compared some types of advanced vehicles with travel routes in Surakarta as represent urban area in Indonesia. The test is done using vehicle modeling with MATLAB software simulation. The research was done by using drive cycle data from previous research. The shows hybrid vehicle series need more fuel than parallel type. The size of the combustion engine in the vehicle series is very influential on the performance of the vehicle. With the increasing use of advanced vehicles in urban areas, the use of non-renewable fuels can be suppressed and the impact on the environment can be reduced.

Abstract
This article delivers the application of magnetorheological elastomers (MREs) as a variable stiffness of surround in a loudspeaker. Firstly, the existing surround was replaced by a set of variable stiffness absorber featuring an MREs. In the preliminary stage, the magnetic circuit absorber was evaluated through simulation work. Then, the simulation using the finite element method magnetic (FEMM) was con- ducted to predict the performance of MREs. The applied currents were varied from 0 to 1.5 A with an interval of 0.25 A. Later, the average magnetic flux density obtained from the simulation was used for estimating shear storage modulus and shear loss modulus which taken from actual experimental data. The stiffness obtained by processing shear storage modulus and shear loss modulus with analytical calculation method. Therefore, the performance of MREs could be evaluated. The suspension system MREs which has investigated have good performance, i.e., has a wide range of stiffness.

Abstract
Energy management plays important role in achieving maximum fuel efficiency on plug-in hybrid electric vehicle (PHEV). Capability of PHEV using electric (EV) mode and hybrid (HV) mode can be optimized by selecting efficient mode for known route and traffic condition. Typical intercity commuting traffic can be divided into city traffic and highway traffic. This paper presents measurements of PHEV energy consumption per distance for each city and highway traffic case. In case of full battery consumption, the optimal mode selection strategy is determined for each traffic case. This paper shows that the mode selection strategy using known route and traffic condition can achieve less fuel consumption compared to default PHEV configuration or no strategy.

Abstract
Vehicles are the most important thing to use by human and to make it safe to use, all vehicle need a safe and reliable braking system, the use of frictional brake can raise the probability of braking failure because of high pressure and temperature operation, to make braking safer, there is a new, alternative braking system called Eddy-Current Brake (ECB) that uses magnet in their braking process. This paper aims to know the influence between the shapes of conductor-s face on braking torque using finite element method, using aluminum with mid-iron in one construction to improve the braking torque produced by conductor. Validation was done before starting FEM calculation to achieve accurate FEM settings, the modeling uses ANSYS Electronics Desktop. The shapes used on conductor-s face are sawtooth, half-circle, and square. The highest braking torque performance on these variables are 15.39213, 16.40432, and 14.25 Nm respectively at their critical speed with a magnetic flux of 0.8 – 2 Tesla at all variables.
