Computer based information systems play an important role in modern military combat Vehicles. The crew needs to be able to quickly get information about both the Vehicle and its outer surroundings in order to quickly make the correct decisions. In this report, we describe the development of a prototype new information system for the BvS10 Vehicle, manufactured by BAE System Hägglunds AB in Örnsköldsvik.An important aspect of the system is the time it takes from the point that the information is generated by the Vehicle sensors until it is presented to the user. The system must be able to ensure that it never displays information that is out of date. Thus, it is important to create a layer and component based architecture for the solution, making it possible to control, in detail, the information?s age as it moves through the system.

The purpose of this master thesis is to construct a steering transmission, for a trackedVehicle, containing two hydraulic circuits which are connected. The steeringtransmission should be mechanical to avoid steer-by-wire.BAE Systems Hägglunds has in an earlier study examined a system with two hydraulicpumps and one hydraulic motor, but the safety of the system wasn?t sufficient.To achieve sufficient redundancy there must be two hydraulic motors, which arecontrolled separately. When the two systems are connected in one point, this point is acritical part of the system because it directly affects both circuits. If one of the hydrauliccircuits fails the other should be able to operate independently as a steeringtransmission.

At the plant of Sandvik do Brasil in São Paulo there is a need for improving the transport of inserts between the plant building and the stock building. The idea is to install a system with an Automated Guided Vehicle (AGV) to take care of this transportation. The purpose of this report is to present which demands there are on the system and to find the best solution according to the demands.To conclude this work a study was made of the plant and the AGV technology was examined. Several providers of AGV solutions were contacted to get information about prices and detailed solutions.The conclusion was that the most suitable system for this application is a small unit load Vehicle using inductive wire as guiding system..

The subject of this bachelors degree project is an interior layout for road ambulances.Landstinget Västernorrland (LVN) wanted a layout concept that would be used to com- municate their design intentions to the ambulance producers during their purchase process.Designing ambulance interiors is an extremely complex process since there so many fac- tors to take into consideration. It ?s not just about taking the equipment and place it where there is space left in the cabin. You have to start with the user in focus and the tasks that are to be performed in the ambulance environment.It ishard to find design solutions that will fit 100% of the ambulance personnel?s working routines for 100% of the tasks.

Good comfort for the driver of a construction machine is crucial. Gearshift comfort is an important part of the total comfort. Volvo Construction Equipment Components has a simulation environment of the powertrain, SimPow, which is implemented in Matlab/Simulink. SimPow is mostly used for simulation of control strategies and performance. In order to be able to study gearshifting comfort, Volvo has an interest in developing new models for SimPow.

Heavy duty Vehicles often have problems with traction during the winter periods. For Vehicles that can lift tag axles it is possible to increase the normal force on the driven axle by lifting one or more tag axles, this will then increase the propulsive force of friction. This however increases wear on both road and Vehicle. A possibility to reduce the wear while achieving nearly equivalent traction compared to lifted tag axles is to allow the Vehicle to regulate the normal force by lowering the pressure in the air suspension associated with the tag axles or by the lifting of these axles. The Vehicle would then by itself be able to set just the right amount of normal force on the drive wheels to avoid unnecessarily high normal forces while maintaining sufficient traction.The purpose of the report is to find out which parameters affect heavy duty Vehicles when driving on slippery slopes and how traction can be improved.

When farm animals are transported there are several factors that can affect their welfare. If the Vehicle has an accident the welfare of the animals transported will probably be compromised. The aim of this study was to make a survey of accidents with animal transportation Vehicles in Sweden. The survey included the number of accidents from January 2000 to May 2014, the cause of the accidents and how the animal welfare was affected by the accident. The authorities which were likely to have reports about accidents involving animal transports were contacted. There were no collected records about transportation accidents and the authorities referred to eachother for information.

When the emissions from the diesel trucks today accounts for a large part of the total emissions from the road traffic, the trend with a more extensive use of diesel trucks for transportation will therefore lead to increasing carbondioxide emissions to the atmosphere. Because of the fact that technical progress in the form of optimized engines and shifts in the means of transport sometimes result in even greater emission levels, other solutions to this problem must be studied to decrease the emissions of carbondioxide from the diesel trucks. The purpose of the thesis is to show how a decrease of the carbondioxide emissions from diesel trucks in Sweden can be achieved in a costeffective way by the use of a carbondioxide tax and a differentiated Vehicle tax. The method used in order to fullfill the purpose of the thesis is studies of literature, mainly of public government reports. Literature of enviromental economics will be used to show the need of a tax and how to determine the dynamic effective carbondioxide tax in steady-state.

Due to the new demands put upon combat Vehicles of today the development quickly strives for-ward. With developers and experts across the globe working to meet the needs of tomorrows armies. The question we ask ourselves is what will be the characteristics of these Vehicles. In order to be able to categorize combat Vehicle and analyze its characteristics we use the principles of war. Based on J.F.C Fullers theory from the early 19 hundreds that anything can be analysed using these principles, through a modern interpretation of the Swedish army, we can categorise the present and future abilities of combat Vehicles.

The purpose of the present study was to examine effects of driver, Vehicle, and environment characteristics on Collision Warning System (CWS) design. One hypothesis was made that the capability of collision avoidance would not be same among a driver, Vehicle, and environment group with different characteristics. Accident analysis and quantitative analysis was used to examine this hypothesis in terms of ?risk? and ?safety margin? respectively. Rear-end collision had a stronger focus in the present study.

The Swedish market for Vehicle inspection is re-regulated since June 2010. More than four years after the re-regulation there are eight companies in the market. Two of these companies are a result of the former monopolist's owners divided the business among themselves. The remaining six companies have entered the market through acquisitions or by building up their business from scratch, these are known as new entrants in the study. The competition has developed slowly and the former monopolist still has the highest market share.

In motorsports competition, safety reasons require that the Vehicle is equipped with some form of protective roll cage. The roll cage should withstand the forces involved in a collision to protect the driver and the co-driver from the Vehicle body deformation. The roll cage also works to protect the Vehicle from excessive deformations to more easily make any repairs afterwards. For the roll cage to be certified and approved for motorsports competition, it requires that the cage is built after one of the recommended options. One of those options is to design the roll cage like a cross-construction at the driver and co-driver doors.

The aim of the Master?s Thesis work is to study and develop algorithms for autonomous travel of a UGV (Unmanned Ground Vehicle). A Vehicle for the mounting of sensors has been constructed in order to perform the work. Since the UGV is to be used outdoor in urban areas, GPS can be used. To improve precision and robustness, inertial navigation is used in addition to GPS, since GPS reception is likely to be diminished in such areas.

As trucks are getting more and more advanced, information about their weight has become a key factor for controlling them in a more fuel efficient and safe manner. Knowing the mass of a heavy duty Vehicle in real time has been a difficult challenge for the truck manufacturers. With the processing power for electronic control units in trucks steadily increasing, more advanced algorithms for calculating the mass has been developed, but at the moment there still is a wish for better performance.Since there is a lack of good information regarding the external forces acting on the Vehicle, forces that depends on the slope of the road, foundation of the road and the wind, the methods have to be able to disregard these. Such an approach, based on an indirect least square solution, has been evaluated in this thesis. The results have been promising and based on these a recommendation about further evaluation has been made..
