Electric mobility scooters are increasing in popularity and are used extensively by individuals with mobility impairments to conduct activities of daily living. Scientific literature on the safety and efficacy of scooters in winter conditions is sparse and the current technical standards for scooters do not mandate testing in these conditions. This study paves the way for more rigorous standard testing by: 1) Describing a novel, motion-capture based method to quantify the tractive performance of scooters; 2) Describing methods to create a wide variety of simulated winter conditions; 3) Presenting pilot-test results of a scooter driven in these winter conditions. The outcomes of this study are significant because it is the first study to evaluate the performance of a scooter in winter conditions. Furthermore, it constitutes the first phase of a broader initiative to develop a rigorous, new winter test method for scooters and drive improvements in safety, performance and design.

This diploma thesis deals with the design and realization of function pattern of off-road four-wheel vehicle for seniors. First part of the work consist of research of current commercial vehicles for the elderly, as well as small four-wheeled off-road vehicles and their individual design elements. In this part of the work were also dismantled the proposed legislation allowing legal movement of vehicles on public roads and seniors ergonomics. Another section dealt with the proposal of possible variants for solving the essential structural elements of the vehicle. The last major parts of the work deals with detail description of each selected construction elements of the vehicle. Functional pattern has been manufactured and tested. At the end of this work were published the results of testing of the vehicle and also were proposed possible changes of design.

The work deals with a design of an electric mobility scooter for seniors or people with limited mobility with regard to technical, ergonomic and aesthetic requirements. The final design is based on the results of design and technical analysis. Emphasis is placed on the needs of the target user, for whom the scooter means freedom of movement. The design solves insufficient storage space even for larger luggage, thanks to the different arrangement of internal components. We managed to create a product with a more psychologically friendly expression, with optimal ergonomics, acceptable to the wider environment
