Abstract: A method for fail-safe resolver excitation includes generating a resolver excitation signal and providing the resolver excitation signal to an input of a first resolver control circuit and to an input of a second resolver control circuit. The method also includes, in response to the first resolver control circuit detecting a fault in the resolver excitation signal provided to the first resolver control circuit: biasing, using the first resolver control circuit, a first resolver amplifier; and communicating, via a communication bus between the first resolver control circuit and the second resolver control circuit, an indication to the second resolver control circuit that the first resolver control circuit detected the fault in the resolver excitation signal provided to the first resolver control circuit.

Abstract: A method of operating an oxygen sensor system is provided where the system includes an oxygen sensor, the oxygen sensor including a pump cell, and wherein the oxygen sensor is connected to associated circuitry such that the associated circuitry controls operation of the pump cell. The pump cell includes a pump line connected to a pump electrode of the pump cell and a return line connected to a return electrode of the pump cell. The method includes, subsequent to a diagnostic process, raising the potential of the pump line for a predetermined period of time by injecting current onto the pump line.

Abstract: An oxygen sensor is in a system including compensator circuitry connected to the oxygen sensor. The oxygen sensor includes a pump cell and the compensator circuitry includes a feedback control loop which includes a digital compensator which determines and outputs a compensation current to the pump cell or adjusts a pump cell voltage. A method of controlling the oxygen sensor includes, subsequent to a period of time when the feedback control loop is disrupted, pumping a balancing current into or out the pump cell for a balancing time interval, the balancing current and/or the balancing time interval is dependent on a current pumped into or out of the pump cell prior to the feedback control loop being disrupted.
