1. A speed control for a vehicle having an electric power source and an electric drive motor including means for generating a magnetic field;

  • a semi-conductor means having an electrical output which is a nonlinear function of its distance from said field generating means;

    field;

    means for supporting the semiconductor device and the magnetic field generating means for relative motion toward and away from one another; and

    means for controlling power flow from the power source to the drive motor as a function of the output of the semi-conductor device whereby the power flow is a non-linear function of the relative position between the semi-conductor device and the magnetic field generating means.
