A controller for controlling a moving object, a method of controlling that object, and a sensor for use in such a controller.

摘要

In order to control a movable object (100) such as an automobile, the differential of acceleration is derived and used as control information. In order to derive that differential, a value representing the acceleration may be differentiated, but preferably a sensor (111,112) is provided which generates a direct measurement of the differential of acceleration. In one example of such a sensor, a pendulum (1) has a coil (3) thereon which interacts with the magnetic field of a magnet (2) on a casing (10) supporting the pendulum (1). A current is supplied to the coil (3) such as to generate a force resisting movement of the pendulum (1). It is then found that the voltage across the coil corresponds to the differential of acceleration.
