Basic
The car still use normal pedal to accelerate and slow down ( brake ) the car. When we press the accelerate pedal, the corresponding wire send information to the power supply and the power supply will supply some current to the Maglev device. as the current arrive the Maglev device, it will flow around the superconductor through the wire that intertwined that superconductor. Thus, the superconductor becomes impermanent magnet. The permanent magnet repels with the impermanent magnet, which will produce movement of the wheel
Forward and Backward Control
This thing can be controlled by changing the flow of current either it moves forward or moves backward. According to blab la bla ( what law? ). If we want to move forward, we just press the accelerator pedal and the current will flow forward, thus resulting the forward movement of the wheel. Otherwise, if we want to reverse or moving backward, we just use the reverse gear. The reverse gear will send instruction to the power supply to produce the current flow backward, then the wheel will turn backward.
Speed Control
We can control the speed by pressing the accelerator pedal itself. The more we press, the more current will flow through the Maglev device, thus the movement of wheel will increase. Otherwise, when we release the pedal, few current will flow through the Maglev device and the movement of wheel will decrease.
