A method includes determining a current slew rate associated with a motor of the steering column, determining a speed slew rate associated with the motor, determining a current and speed slew rate threshold for the motor, and determining whether the current slew rate or the speed slew rate indicates a pinch event based on a comparison of the current slew rate, the speed slew rate, and the current and speed slew rate threshold. The method also includes, in response to a determination that at least one of the current slew rate and the speed slew rate indicates a pinch event, selectively instructing the motor to one of stop operation and reverse operation for a calibration period and, in response to the pinch event having a magnitude that is less than a pinch event threshold, selectively instructing the motor to continue operation.

An auxiliary unstow mechanism for a vehicle steering column includes a telescope actuator assembly. The auxiliary unstow mechanism also includes a first electronic control unit (ECU) in communication with the telescope actuator assembly to control the telescope actuator assembly. The auxiliary unstow mechanism further includes a latch actuator operatively controlling a latch assembly that controls a locked condition and an unlocked condition of vehicle steering column axial position. The auxiliary unstow mechanism yet further includes a second ECU in communication with the first ECU and the latch actuator, the second ECU controlling the latch actuator.

Technical solutions are described for providing failsafe assist torque in steering systems. An example method includes determining, by a first controller, a first assist torque signal using a first set of torque sensor signals from a first sensor and a second set of torque sensor signals from a second sensor, the first sensor corresponding to the first controller, and the second sensor corresponding to a second controller. The method further includes determining, by the second controller, a second assist torque signal using the first and second sets of torque sensor signals. Further the method includes generating, by a motor, an assist torque using the first and second assist torque signals, and in response to the first controller receiving a diagnostic signal indicating a failure of the first torque sensor, determining by the first controller, the first assist torque signal using only the second set of torque sensor signals.

Technical solutions for controlling operation of an electric machine by a control system are provided. The control system comprises an inverter and a controller performing a first operation to produce a first output data representing a motor control current command in a first time period beginning at one of a plurality of initial times occurring at a first periodic timing interval. The controller also performs a second operation upon the first output data to produce a second output data in a second time period. The controller also performs a third operation at a periodic command time to produce a motor control voltage command using the second output data in response to satisfaction of a timing criterion. The timing criterion is based upon comparing the command time and occurrence of a posting time after the initial time. A method of enforcing timing restriction to synchronize non-deterministic motor control events is also provided.
