During some operations the brake system on a truck is exposed to severe stress and hightemperatures. To ensure function and safety during these operations, Scania test thebrake system both test rigs and in actual trucks around the world. There are tests thatare regulated by law that the truck manufacture must pass to be allowed to sell its vehicleand there are Scania internal tests to validate performance and quality. One of thoseinternal Scania tests is a severe test with extreme temperatures, called the Rossfeld-test,performed at the Rossfeld slope in the German Alps. The idea is that the truck rolls downthe slope only accelerated by the downhill force where the wheel brakes will be appliedwhen the vehicle speed passes 35 km/h and released when going slower than 25 km/h,this is repeated until the end of the slope. No auxiliary brakes are used. The objective of this thesis is to investigate the possibility of using a Scania truck as a testbench to perform a simulation of a truck rolling down a descent. And by this investigatethe possibility of recreating a wheel brake test as the Rossfeld-test on a horizontal roadby using the engine as the source of acceleration instead of the gravity. In this thesis a model was developed in Matlab/Simulink which through the CAN-busnetwork in the truck could request engine torque and brake pressure. Given the roadtopography of the actual German slope, the corresponding downhill force was calculatedand requested of the engine and brake pressure was applied when the truck passed 35km/h and released again when reaching 25 km/h. The model was verified against roll-tests performed in known slopes with three, eightand sixteen percent gradient. Results from simulations with the truck showed a biggerinconsistency with respect to acceleration and gear selection when requesting a low torqueas with the simulation of a 3% slope. This was not the case when requesting a highertorque as when simulating a 8% or 16% slope. The results showed that at a highertorque request the acceleration was more consistent but the truck was still acceleratingslower than the corresponding roll-test and an extra twelve percent of torque was addedto mimic the acceleration of the roll-test. The first 3000 m of the Rossfeld-slope wassimulated by driving in a circle and the temperature measurements catches the differencesin temperature build up as in the result from a real Rossfeld-test performed in the Germanalp. This shows there is a potential in this type of simulation.

ITC/USA 2015 Conference Proceedings / The Fifty-First Annual International Telemetering Conference and Technical Exhibition / October 26-29, 2015 / Bally's Hotel & Convention Center, Las Vegas, NV / This paper discusses the telemetry system used to monitor the performance of a solar-powered vehicle during testing and competitions. Car-side systems collect and transmit data onboard over an ISO 11898 / CAN bus. A bridge then converts this data into TCP/IP packets, which are transmitted via Ethernet to a Wi-Fi access point. The data is distributed through an IEEE 802.11N 5GHz mesh network to provide real time data to remote computers running telemetry software. This software displays and logs data from the car, allowing team members to monitor the vehicle.

This diploma thesis, processed under the name: External system of measuring parameters of vehicles with support of diagnostic protocols integrated in Ethernet networkon a cylindrical dynamometer, deals with the definition of parameter variables that are important for vehicle tests on a cylindrical dynamometer. After determining these variables, a measuring module, which is designed to retrieve data from individual sensors located in the vehicle, is implemented via an OBD II diagnostic connector connected to the vehicle data bus CAN-BUS. The measuring module is integrated into the existing cylindrical dynamometer system at the Mendel University Testing Center in Brno, where the system was tested on a real vehicle.

Exoskeletons are getting popular day by day due to their abilities in helping people. Exoskeletons can be used to help people gain motor senses through rehabilitation. It can also help healthy people to augment their abilities. These exoskeletons need to be strong yet light, so that the human body can support the exoskeleton, while the exoskeleton can support the activity that is being performed. This calls for under-actuated systems, which help in avoiding unnecessary mass due to additional actuators, while providing the same movement capabilities. This thesis describes in detail about two such under-actuated upper body exoskeletons which can be used for lifting loads. The design of such exoskeletons and novel control techniques for comfortable usage is discussed in detail. / Master of Science / Exoskeletons are assistive devices which can help people in several ways. An exoskeleton can help people who are affected with stroke by enabling them to walk through rehabilitation and physiotherapy. It can also help people to perform beyond their capacity in terms of physical activities. This could be to lift more load than possible, run faster than usual. This thesis describes the design and working two such exoskeletons which can be attached to the upper body. These exoskeletons can be used by people to lift loads which would require a lot of effort and muscle activity. The addition of these exoskeletons potentially reduce the muscle activity on the user and helps avoiding injuries in long term. Such exoskeletons have to be light weight so that they do not defeat the purpose of reducing muscle activity. This problem is solved by using under-actuated systems, because a significant mass of the exoskeleton is taken by the actuators such as the motors. Using under-actuated systems help in lowering the mass of the exoskeleton, while still being able to perform the same kinds of motion. This thesis also talks about how these exoskeletons can be controlled such that the load is being lifted with minimal efforts, and being aware of the loads it is lifting to provide the correct amount of torque, above or below which can lead to the motor shooting up or down causing muscular discomfort and injuries in the arm.
