Abstract
A personal mobility vehicle is steered by handlebars. A lever is mounted on the handlebars and rotatable in either of two opposite directions by the hands holding the handlebars. A potentiometer connected to the lever comprises a wiper on a resistive track, centered by a spring. The track has a central null area formed by material of lower resistance, so that the output voltage is constant. When the lever is moved away from the centered position, the wiper moves along the track and the output voltage rises or falls. A controller controls the speed and direction of the vehicle in response to the output voltage of the potentiometer. When the wiper is on the null area, the controller stops the vehicle. The size of the null area facilitates ensuring the centered position coincides with the null area, so the vehicle stops when the lever is released.
