摘要： A signal detecting device detects, as analog voltage signals, a current flowing through an exciting coil of an electric power generator, a source voltage and a temperature of a regulator that change as a current is fed to the exciting coil by an FET. These analog voltage signals are subjected to A/D conversion by a single A/D converter circuit. The detected current is subjected to A/D conversion in a period during which the FET is ON, while the detected source voltage and the detected temperature are subjected to A/D conversion in a period during which the FET is OFF.

摘要： A battery condition detection apparatus is composed of a semiconductor element, and a lead frame and mold resin. The semiconductor element is composed of plural diodes connected in series as a temperature sensitive element for detecting a temperature of a battery and a communication circuit for outputting a temperature detection result to an outside device such as ECU mounted on a vehicle. The semiconductor element is mounted on the lead frame having high heat conductivity rather than that of the mold resin. The semiconductor element and the lead frame are completely sealed with the mold resin. The battery condition detection apparatus is mounted on a battery case which accommodates the battery of a vehicle so that the lead frame of high heat conductivity is directly contacted to the battery case. The heat conductivity of the lead frame is more than 100 times of that of the mold resin.

摘要： An apparatus is disclosed that drives an inductive load according to a control signal from an external controller transmits temperature data to it for indicating a condition of the inductive load through a line driver. The external controller regenerates the control signal according to the temperature data. According to the control signal, the apparatus operates a pair of power supply circuits to complementarily supply power to the load. Thermal conditions of the power supply circuits and the line driver are monitored for detecting an overheat condition. The transmission of temperature data to the external controller is enabled as long as no overheat condition is detected in both of the power supply circuits and line driver. If an overheat condition is detected in at least one of the power supply circuits and line driver, heat protection is performed and the overheat condition is communicated to the external controller.

The apparatus comprises a detecting unit detecting an actual amount of the charge/discharge current and a receiving unit receiving information indicating generating operations of an on-vehicle generator. The apparatus also comprises a control unit controlling the generating operations of the generator so that the charge/discharge current keeps a given value specified, on the basis of the detected actual the charge/discharge current and the received information. The apparatus also comprises determining and setting units. The determining unit determines whether a voltage of the battery satisfies a given condition for the voltage, by monitoring the voltage in a state where the generating operation of the generator is controlled. The setting unit sets, as an amount of offset of the charge/discharge current, a charge/discharge current detected when it is determined that the voltage of the battery satisfies the given condition.

摘要： A control apparatus such as an ECU, that controls the generator of a vehicle, measures the engine rotation speed and generator rotation speed while the engine is idling, and calculates and stores the ratio of the speed values. Thereafter when the vehicle is being driven and the current value of generator rotation speed is required, it is calculated based on the stored ratio value and the currently measured speed of the engine. The processing load on the ECU is thereby reduced, since generator rotation speed measurement processing is performed only in the idling condition.
