Welcome to Tatry Group AEV Project Portfolio!
The Advance energy Vehicle is designed, so the national park limits traffic that travels on the roads in the park but offers good views for the tourists. The AEV design runs on the lowest amount of power to not strand the tourists in the middle of nowhere. When developing the AEV design, the cost and energy-efficient as possible due to power limitations. The goal was to make the AEV as light as possible so that weight would not be an obstacle when programming the vehicle’s power usage during movement. The park already has a monorail system in operation, and the AEV designs are being used on the monorail. The system pulls a passenger car with stops along the route to allow the people to leave the parked vehicle or view the most exciting areas.
The AEVs will focus on energy management, operational efficiency, and operational consistency. Energy used per mass of the AEV will be measured and recorded during the AEV operation. The goal is to successfully pick up and deliver the tourists in the cabin while meeting the operational requirements, design constraints and minimizing the energy/mass ratio. Due to the variation and instability of the area, the monorail may have slight variations over time due to shifting faults, therefore, the AEV should not depend on a specific track. The AEV should have operational consistency in which the AEV performs consistently regardless of the type of cargo or power supply (battery).
The Performance Test lab was to create two different AEV vehicles and determine which system is a better, energy-efficient vehicle. Using the experimental results it can be determined which vehicle is better. Also, it can be seen that for both design prototypes, energy consumption is almost similar, but design two energy usage is less than design 1. This is because both designs 2 use a servo system. Design 1 uses reverse command when it reaches the mark, long bursts of energy every time reverse is activated to stop the vehicle, requiring more power. Therefore, energy use is a concern when choosing between these two designs. As for that, design 2 is a better choice. After performing multiple trial and error runs, the final code was selected and proved successful during the Final Performance Test. The final AEV weighed 237 g, consumed about 751.57J/kg, and took 82.0 seconds to complete the whole track — 25 m
