摘要： A flow rate detector includes a detection circuit, which is configured to output as an analog signal a voltage in accordance with a flow rate of air flowing through an intake pipe, and a conversion circuit, which is configured to convert the analog signal input from the detection circuit to a digital signal based on an analog-to-digital conversion characteristic to output the digital signal. The analog signal that corresponds to a forward flow direction and is input to the conversion circuit is set to have a value larger than an input voltage range in which a missing code may occur in the analog-to-digital conversion characteristic.

摘要： A pressure sensor includes: a housing; a substrate that is fixed within the housing, that includes a first side that is in contact with a fluid of an exhaust aftertreatment system, and that flexes based on a pressure of the fluid; a first voltage divider that is connected between a first reference potential and a ground potential and that varies a first potential based on flexing of the substrate; and a second voltage divider connected in parallel with the first voltage divider between the first reference potential and the ground potential and that varies a second potential based on flexing of the substrate. A pressure control module is configured to selectively switch switches to connect and disconnect different reference potentials to and from an amplifier, to sample an output of the amplifier, and to convert samples of the output of the amplifier into corresponding digital values.

摘要： An anomaly determination apparatus determines an anomaly of a current control apparatus which supplies a control current to a control target and includes a current anomaly determination section. The current anomaly determination section is configured to compare a normal numerical range within which a state quantity changing with the control current falls in a particular state with a particular state quantity which is the state quantity corresponding to the control current generated by the control current generation section in the particular state, and determine that at least one of the reference resistor, the reference current generation section, and the control current generation section is in an anomalous state in the case where the particular state quantity has deviated from the normal numerical range. By using the current anomaly determination section, the anomaly determination apparatus can determine an anomaly of the current control apparatus.

摘要： An inter-connect circuit (ICC) device for a fuel delivery system of a vehicle is disposed between an engine control unit (ECU) and a fuel control device. The ECU transmits a drive pulse to the fuel control device by way of a drive pulse line passing through the ICC device. The ICC device includes a housing and a sense circuit. The housing has a first side that is connectable to the ECU and a second side different from the first side that is connectable to the fuel control device. The sense circuit is disposed within the housing. The sense circuit is electrically coupled to the drive pulse line by way of a sense circuit line and is communicably coupled to the ECU by way of a data communication line.

摘要： A method for an engine may comprise, responsive to a first condition comprising a reference voltage of a first exhaust oxygen sensor operating in variable voltage mode increasing above a threshold voltage, determining a change in an output of the first exhaust oxygen sensor corresponding to the increase in the reference voltage, correcting the output of the first oxygen sensor based on the output change, and adjusting engine operation based on the corrected output. In this way, the accuracy of air-fuel estimates based on the exhaust gas sensor can be preserved, and closed loop fuel control of the engine can be maintained even when the exhaust oxygen sensor is operating VVS mode, thereby reducing engine emissions, increasing fuel economy, and increasing vehicle drivability.

摘要： A system, method and device for mass airflow sensor signal processing includes a microcontroller, a mass airflow sensor and an engine PCM. An analog-to-digital converter (ADC) converts a first output signal from the mass airflow sensor to a first VDC value. A digital-to-analog converter (DAC) converts a second VDC value to a second output signal associated with the mass airflow sensor. Transfer functions are obtained from a flow bench using the mass airflow sensor, performance air intake components, and stock air intake components. The microcontroller determines, from the first VDC value, a corresponding actual flow rate. From the actual flow rate, a corresponding stock VDC value is determined. The stock VDC value is then output to the DAC for conversion to the output second signal associated with the mass airflow sensor for communication to the engine PCM.

摘要： A method of estimating an injection pressure for an internal combustion engine of an automotive system is disclosed that is well-suited for use with a digital pressure sensor, which periodically acquires injection pressure signals. An updated injection pressure value is calculated starting from an injection pressure signal and compensated with a pressure-correcting parameter, based on an elapsed time from the injection pressure signal acquisition, an actual engine speed and an actual fuel injection quantity.
