SENSOR-BASED VEHICLE CONTROL METHODS
First Claim
1. A method of controlling motion of a vehicle comprising the following steps:
- its rectangular sensor unit detects the Cartesian coordinates (x, y) of a position specified by a human'"'"'s hand;
its computing unit computes a desired translation speed and a desired rotation speed using the coordinates (x, y); and
its motion-control unit controls the vehicle'"'"'s motion with the desired translation speed and the desired rotation speed.

Abstract
The novelty of this invention is that the vehicle'"'"'s two degrees of freedom in motion is controlled by a single action of a driver. With this method, a driver can control a vehicle easily and intuitively. This invention might make it possible for impaired people to drive vehicles at their will for the first time. First, a sensor unit of a vehicle detects the Cartesian coordinates (x, y) that are specified by the driver. Second, a computing unit of the vehicle converts the coordinates (x, y) into a desired translation speed and a desired rotation speed, or into a desired translation speed and a desired curvature. Third, the motion control unit of the vehicle controls its motion using the desired translation speed and rotation speed, or the translation speed and curvature.
