  • Patent number: 9719836
    Abstract: A high-temperature resistance is disposed in an internal passage and has its energization controlled based on an intake-air flow rate in the passage to increase/decrease a heat generation amount. A first low-temperature resistance constitutes a bridge circuit which has its energization state changed according to the heat generation amount of the high-temperature resistance. The first low-temperature resistance varies its resistance value according to intake-air temperature. A second low-temperature resistance is an element, which is not incorporated into the bridge circuit and varies its resistance value according to intake-air temperature to increase/decrease an energization amount. The second low-temperature resistance is provided on a substrate. Another bridge circuit produces an intake air amount detection signal using an electrical signal generated by operation of the high-temperature resistance and the first low-temperature resistance.

  • Patent number: 9052223
    Abstract: A flow meter outputs a frequency signal, which corresponds to an air flow quantity of intake air to be supplied to an engine. In an engine control unit, when a sensed value of the air flow quantity, which is obtained based on the frequency signal, is within an estimated air flow quantity range, which is estimated based on an operational state of the engine, the sensed value of the air flow quantity is determined as a measurement value of the flow meter. In contrast, when the sensed value of the air flow quantity is out of the estimated air flow quantity range, a median of the estimated air flow quantity range is determined as the measurement value of the flow meter.

  • Patent number: 8904854
    Abstract: An air flow measurement device arranged in an intake passage includes a bypass passage having an inlet from which a part of a main flow of an intake air is introduced, and an outlet from which the introduced intake air flows out. A sensor is located in the bypass passage to generate an electrical signal, and the bypass passage communicates with the intake passage through a hole portion. The outlet is open toward a downstream side of the intake passage in a flow direction of the main flow of the intake air. The hole portion is located within an outlet projected area that is provided by projecting an open area of the outlet in straight and toward upstream in the flow direction of the main flow on a projection surface perpendicular to the flow direction of the main flow.

  • Patent number: 8909486
    Abstract: A flow measuring device includes a flow rate detecting part, an analog/digital conversion part, and a signal processing part. The flow rate detecting part detects a flow rate of air flowing through the passage, and outputs a flow voltage signal, which is a voltage in accordance with the flow rate. The analog/digital conversion part converts the flow voltage signal from the flow rate detecting part into digital data, which is flow digital data. The signal processing part performs calculation processing upon the flow digital data, which includes averaging of a predetermined number of consecutive pieces of the flow digital data, and outputs the averaged flow digital data as a flow rate signal. The predetermined number is equal to or larger than two.
