Moving object controller containing a differential of acceleration measurer

摘要

In order to control a movable object 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 is provided which generates a direct measurement of the differential of acceleration. In one example of such a sensor, a pendulum has a coil thereon which interacts with the magnetic field of a magnet on a casing supporting the pendulum. A current is supplied to the coil such as to generate a force resisting movement of the pendulum. It is then found that the voltage across the coil corresponds to the differential of acceleration.
