Abstract: Vehicles and related systems and monitoring methods are provided for detecting a loss of isolation on one side of a power converter. One method involves monitoring a normalized voltage input to a power conversion module coupled to the electric motor, in response to the normalized voltage exceeding a diagnostic activation threshold, determining a first number of instances of a range between successive extremas of the normalized voltage exceeding a loss of isolation range threshold over a diagnostic window of time, and automatically initiating a remedial action when the first number is greater than a loss of isolation detection threshold.

Abstract: A control module-implemented method for estimating an end of life a belt transferring torque between at least two rotating members of a belt drive system includes monitoring a plurality of belt parameters during a life cycle of the belt and determining an instantaneous damage factor of the belt based on the plurality of belt parameters. The end of life of the belt is estimated based on the instantaneous damage factor.

Abstract: A multi-position actuator includes a solenoid selectively energized to extend a rod. The actuator also includes a push-lever pivotably mounted to the rod and a crank-arm rotatably mounted on a first axis. The crank-arm includes multiple engagement elements arranged on a diameter centered relative to the first axis, and also includes a projection. The push-lever engages one of the engagement elements to rotate the crank-arm about the first axis in a forward direction when the solenoid is energized. The actuator additionally includes a pivoting locking-lever that blocks rotation of the crank-arm in forward direction and a one-way-clutch that blocks rotation of the crank-arm in reverse direction when the solenoid is de-energized. Furthermore, the actuator includes a slider-box lever having first and second slots. The projection slidably engages the first slot. The second slot is engaged with and operates an external device when rotation of the crank-arm swings the slider-box lever.

Abstract: An electric vehicle battery control system including a first electric motor configured to propel a vehicle in a drive mode in response to a drive current, a second electric motor operative to generate a back electromotive force voltage in a fault mode, a battery, having an open circuit battery discharge voltage, for generating the drive current for coupling to the first electric motor, and a vehicle controller for limiting the drive current in response to a difference between the back electromotive force voltage and the open circuit battery discharge voltage being less than a threshold voltage difference.

Abstract: A belt drive system for an internal combustion engine rotatably coupled to a rotary motor is provided. The internal combustion engine includes at least three cylinders each having a piston operable to turn a crankshaft. The belt drive system includes a belt and a controller. The belt is coupled to crankshaft of the internal combustion engine and the rotary motor; and the controller is operatively connected to the rotary motor, wherein the controller causes data processing hardware to perform the following operations: apply a torque to the rotary motor; and change the torque of the rotary motor prior to a change in a rotary speed of the internal combustion engine to maintain a predetermined tension in the belt and reduce a rotary motor torsional response through the belt drive to the torsional vibration input from the internal combustion engine.
