  • Patent number: 11904959
    Abstract: Systems and methods are provided for detecting water within an electronic power steering assembly. A sensor assembly includes a resistor and a water-sensitive capacitor arranged to provide a series resistor-capacitor (RC) network having a cut-off frequency that is a function of a capacitance of the water-sensitive capacitor. An oscillator provides an excitation to the series RC network having a known frequency, such that the series RC network provides an output in response to the excitation. An envelope detector receives the output of the series RC network and generates an output representing an amplitude of the output of the series RC network. A microcontroller determines if water is present within the electronic power steering assembly from the amplitude of the output of the series RC network.
