Abstract
Technical solutions are described for detecting an error in an inverter associated with a motor of a power steering system and operating the power steering system in response to the error. An example system includes a transistor pair that selectively provides power to a corresponding phase coil of the motor. The system further includes a detection module that detects a resistance error in the transistor pair by monitoring a voltage across a shunt resistor of the transistor pair in response to a gate drive command applied to the transistor pair. The system further includes a mitigation module that selects a mode of operation of the inverter based on the resistance error. The system also includes a motor control module that controls the inverter according to the mode of operation.
