Title: Relative position detection and control device for motor vehicle

Abstract: A relative position detection-and-control device is designed with multiple Hall Effect sensors. In one embodiment, the multiple Hall Effect sensors comprise two different types of Hall Effect sensors. The two different types can be linear and digital. The output of the sensors is used to determine the position of an accelerator control, such as a twist grip, and to control an engine or motor in accordance with the operator demand evidenced by the position of the accelerator control.
