Abstract: A magnetic bearing control apparatus and a vacuum pump which do not require a displacement sensor, which enable control with high accuracy, and which are small and low cost. A rate of change (di/dt) that is a time derivative of a current value Im flowing through an electromagnet varies in accordance with a magnitude of a displacement of a gap between a target member and the electromagnet. The rate of change (di/dt) can be obtained by detecting a voltage value Vs that is generated at both ends of an inductive element. Therefore, by detecting the voltage value Vs, the magnitude of the displacement of the gap can be estimated by calculation. Inductive elements are connected in series to electromagnets and the voltage Vs between the inductive elements is detected by the differential input amplifier. A single period of switching of a PWM switching amplifier is constituted by a current control period of the electromagnet and a displacement detection period for detecting the rate of change (di/dt).

Abstract: From each of in-vehicle units in vehicles, a travel behavior data indicating a travel behavior of the vehicle is received and recorded in a travel history database. The travel behavior data of the vehicles are read from the travel history database; an avoidance action arising in each of the vehicles is detected based on the read travel behavior data. From the detected avoidance actions of the vehicles, a related avoidance action group being avoidance actions arising due to an identical object at different positions at different points of times in different target vehicles is extracted based on an occurrence position and an occurrence point of time of each detected avoidance action. Information on position change of the identical object as a cause of the extracted related avoidance action group is recorded as an alert target data.
