    Abstract: Technical solutions are described for controlling a brushed direct current (DC) motor, including: determining, based on one of a motor current command or an actual motor current, a brush voltage drop across a set of brushes of the brushed DC motor; determining, based on the brush voltage drop, at least one of: a first torque limit based on a supply current value not exceeding a supply current limit, and a second torque limit based on a controller supply voltage value not exceeding a maximum available voltage; determining a final torque limit based on the at least one of the first torque limit and the second torque limit; determining a limited torque command based on a torque command and not to exceed the final torque limit; determining a voltage command based on the limited torque command; and applying a DC voltage to the brushed DC motor based on the voltage command.

    Abstract: A method for determining motor velocity includes receiving motor sensor data from at least one motor sensor associated with an electric motor, the motor sensor data including a plurality of motor sensor measurements and respective time values; determining an average time value based on the respective time values for each motor sensor measurement; generating a first gain value, a second gain value, and a third gain value, the first gain value being generated based on at least the average time value; and estimating a motor velocity based on at least one motor sensor measurement, the average time value, the first gain value, the second gain value, the third gain value, and at least one previously estimated motor velocity.

    Abstract: A method for determining a state of health (SOH) of an electrical connection in a steering system includes, using a processor configured to execute instructions, receiving an input indicative of the SOH of the electrical connection, the input including a resistance associated with the electrical connection, and the SOH corresponding to at least one of an accumulated health (AH) of the electrical connection and a remaining usable life (RUL) of the electrical connection, calculating, based on the received input and usage associated with the vehicle, a first SOH value, calculating, based on the received input and behavior associated with the vehicle, a second SOH value, calculating, based on the first SOH value and the second SOH value, a third SOH value, the third SOH value being an indicator of the AH or the RUL of the electrical connection, and performing at least one action based on the third SOH value.

    Abstract: A method for detecting degradation intermittencies in an electrical connection in a steering system of a vehicle includes, using a processor configured to execute instructions, receiving an input indicative of a plurality of measurements of resistance associated with the electrical connection, calculating, based on the received input, at least one adaptive control threshold, comparing a first measurement of the plurality of measurements to the at least one adaptive control threshold, determining whether the electrical connection has a degradation intermittency in response to the comparison between the first measurement and the at least one adaptive control threshold, and performing at least one action in response to determining that the electrical connection has the degradation intermittency.
