Front-Lighting system of intelligent automobile can automatically provide the shape of lighting which is needed by car in present situation. Adjust and control the shape of lighting in bend. It can take different actions and automatic adjustment to the changes of vehicle driving, according to the road condition, time interval and weather variation .and thus it can realize the control. The paper introduces the AFS system structure diagram, working principle, and working process. It plays an important role in running safety at night.

Abstract: Today's engendering has a rage about faired bikes because they endeavour ergonomic glances as well as speeds. Although it has now graced a fact that most motorcycle accidents occur in darkness due to poor illumination and are more dangerous when the bike is cornering. As per the present contour of headlamps of fairing bikes, the headlamps become stable, giving rider vision at an upright position. These headlights do not provide enough illumination on bent roads and put riders in a vulnerable position. To overcome this dilemma, an alternative lighting system was needed. The goal of the project is to discover a cost-effective explication, increasing the safety and comfort of the rider. This called for cornering lights for faired bikes to persuade the road at the corner. The cornering lights serve riders by illuminating the shadowed area of the curve providing better vision. The Cornering lights can not only be useful in twilight but also bad weather, the rider can have a clear vision and control on the motorbike. The rider may react to the state of danger at an appropriate time. Keywords: Motorcycle Cornering Lights, Smart Headlights, Guidable headlight, Adaptive headlight, cornering headlight, safety technology, deflecting headlight.

Modern automobiles contain more and more mechatronical components to support the task of driving. Such mechatronical components are, e.g., an anti-lock braking system (ABS) and an electronic stability program (ESP) to support driving safety, or a predictive advanced front lighting system P-AFS) to enhance the lighting capabilities of a vehicle on a winding road. P-AFS uses GPS-data to locate the vehicle’s position plus digital map data to predict the curvature of the road in front of the vehicle. Based on this, P-AFS predicts the road scenario and swivels the front headlights accordingly. That way, the headlights follow the road’s curvature and optimally illuminate the road in front of the vehicle. To design, evaluate, and optimize the control algorithms within the electronic control unit (ECU) of the P-AFS component, up to 30 design variables need to be adjusted and tuned to ensure an optimal response of the system to the current road scenario. For this task, numerous time-consuming and costly test drives at night are necessary. This paper introduces a Virtual Reality-based night drive simulator that visualizes the complex lighting characteristics of automotive headlights in high detail and in real-time on a PC-based system. The user drives a simulated vehicle over a virtual test track at night, the vehicle’s motion directly influences the lighting direction of headlights, and the effect of the vehicle dynamics on the lighting can be evaluated directly in the simulator. The system is connected to the control algorithms of a P-AFS component to control the headlights swivelling for a close-to-reality simulation of a P-AFS based lighting system during the simulated night drive. That way, good combinations of the design variables can be found, based on virtual night drives in the simulator system, and the number of real test drives can be reduced significantly. Promising combinations of the design variables then can be validated in a test vehicle during a real test drive a night.

The paper, aiming at status of car networking, researched the key technology of dynamic traffic information services under the condition of car networking, proposed overall system structure based on the framework of car networking. Through traffic perception technology and dynamic induction technology and on the basis of analyzing the entire working process of car networking, the paper also realized the effective management and control on car networking. Experimental results show that this control technology model can better deal with data processing under the car networking.

Management and Command253 are two different words and terms, but military structures use them as synonyms. Military commanders’ authorities are almost equal in meaning to civilian managers’ privileges and power. Comparison between military command and the civilian management system structure, organization, and way of work shows almost full identity and overlapping. The highest in scale and size military systems are national ministries of defense and multinational military alliances and coalitions. Military systems at this level combine military command structures with civilian political leadership and support elements. Therefore, they incorporate both military command and civilian management organizations without any complications, because their nature originated from same source and have similar framework and content. Management of organizations requires communication in order to plan, coordinate, lead, control, and conduct all routine or extraordinary activities. Immediate long-distance communications originated from telegraphy, which was firstly applied in 19th century. Later, long-distance communications included telephony, aerial transmitting, satellite, and last but not least internet data exchange. They allowed immediate exchange of letters, voice and images, bringing to new capabilities of the managers. Their sophisticated technical base brought to new area of the military command and civilian management structures. These area covered technical and operational parts of communications, and created engineer sub-field of science, that has become one of the most popular educations, worldwide. Communications were excluded from the military command and moved to separate field, named Computers and Communications. A historic overview and analysis of the command and management structures and requirements shows their relationships, common origin, and mission. They have significant differences: management and control are based on humanities, natural and social sciences, while communications are mainly based on engineering and technology. These differences do not create enough conditions for defragmentation of communications from the management structures. They exist together in symbiosis and management structures need communications in order to exist and multiply their effectiveness and efficiency. Future defragmentation between military command and communications will bring risks of worse coordination, need for more human resources, and worse end states. These risks are extremely negative for nations and should be avoided by wide appliance of the education and science among nowadays and future leaders, managers, and commanders.
