Abstract: An illustrative embodiment of a fuel injector control system includes a driver that is configured to supply electrical power to a fuel injector. A controller is configured to control the driver by implementing a predetermined sequence of a plurality of states for an injection cycle. The plurality of states each include parameters for supplying electrical power to the fuel injector. The controller selects one of the states to implement as a next one of the states in the sequence based on a characteristic of an activation signal and information indicative of the state corresponding to the characteristic of the activation signal

Abstract: An apparatus is configured to determine the leakage resistance in respect of the positive and/or negative terminals of a vehicle battery. The apparatus includes a first pair of serially arranged resistors connected between the terminals with a first switch connected between the resistors and a second pair of serially arranged resistors connected between the vehicle chassis/nominal ground and the negative terminal or the positive terminal, with a second switch connected between the resistors. A further fifth resistor is connected between the vehicle chassis/nominal ground, and the negative terminal or the positive terminal via a third switch, and a controller is configured to selectively control the switches during processing steps.

Abstract: Compensator circuitry is provided for an oxygen sensor which includes a pump cell and a reference cell. The compensator circuitry includes a feedback control loop which maintains the reference cell at a reference voltage. The feedback control loop includes a digital compensator which determines and outputs a compensation current to the pump cell dependent on a reference voltage measured from the reference cell. The digital compensator also suspends the determination and output of the compensation current for a set time which is dependent on detection of edges in an oxygen sensor heater Pulse Width Modulation signal.

Abstract: A short-circuit pinpointing device for testing a wide-range air/fuel sensor includes a current-sink and a controller. The current-sink is selectively connectable to one or more of sensor-terminals of a wide-range air/fuel sensor that include a reference-terminal, a pump-terminal, a return-terminal, and a tag-terminal. The controller is in communication with the current-sink and the sensor-terminals. The controller controls the connection of the current-sink to the one or more sensor-terminals. The controller also determines one or more status-values based on signals present at the sensor-terminals. The controller also determines a sensor-status of the wide-range air/fuel sensor based on the connection of the current-sink and the one or more status-values.

Abstract: An illustrative embodiment of a fuel injector control system includes a driver that is configured to supply electrical power to a fuel injector. A controller is configured to control the driver according to a predetermined sequence of states for an injection cycle. The plurality of predefined states each include parameters for supplying electrical power to a fuel injector. Each of the states has a corresponding plurality of test parameters. At least one of the test parameters is a target parameter for the state. During each of the states, the controller determines whether at least one of the test parameters is met and determines how to control the driver for a subsequent portion of the injection cycle based on which of the test parameters is met.

Abstract: An apparatus includes a first analog-to-digital converter configured to measure a first reference voltage and a third reference voltage. The apparatus also includes a second analog-to-digital converter configured to measure a second reference voltage and a fourth reference voltage. The apparatus also includes a controller configured to calculate a first resistance ratio, and determine a positive high voltage associated with the positive high voltage direct current input signal based, at least in part, on the first resistance ratio. The controller is further configured to calculate a second resistance ratio, and determine a negative high voltage associated with the negative high voltage direct current input signal based, at least in part, on the second resistance ratio.
