Abstract: A system for haptic feedback for steering system controls includes a touch sensor input detection module and an actuator haptic response driver module. The touch sensor input detection module acquires a touch sensor input from one or more touch sensors of a steering system and identifies a touch gesture type of the touch sensor input. The actuator haptic response driver module determines a desired haptic feedback associated with the touch gesture type and controls a steering system actuator to produce a haptic response based on the desired haptic feedback.

Abstract: A system for grip-based handwheel compensation includes a net handwheel torque moment determination module that determines a net handwheel torque moment between a left grip and a right grip on a handwheel. The system also includes a filter transition compensation module that applies a filter to smooth transitions in the net handwheel torque moment as a bias compensation. The system further includes a handwheel torque compensation module that determines a grip compensated handwheel torque based on a difference between a sensed handwheel torque and the bias compensation.

Abstract: An embodiment of a system of a vehicle includes a power steering system that operates as commanded by control commands, and a control module configured to receive a first control command. The control module is also configured to generate a range signal indicative of a range of command values based on a plurality of input signals, generate a second control command based on a subset of the plurality of input signals, determine whether the first control command is out of the range for longer than a predetermined duration of time, and send the second control command to the power steering system in response to determining the first control command is out of the range for longer than the predetermined duration of time.

Abstract: A control system for monitoring operation of an electric motor includes a plurality of position sensors configured to measure a position of the electric motor, an indirect position estimation module configured to indirectly estimate the position of the motor, and an error monitoring module. The error monitoring module is configured to perform at least one of: comparing a measured position from the plurality of position sensors to an estimated position from the sensor position estimation module, and detecting a failure of at least one of the one or more position sensors based on the comparison; and calculating a difference between the measured position from one of the plurality of position sensors and the measured position from another of the plurality of position sensors, and causing the indirect position estimation module to initiate estimation of the position of the motor based on the difference.

Abstract: Technical solutions are described for mitigating braking torque in a motor of a steering system caused by a FET short. For example, an example mitigation system includes a mitigation module that adjusts a motor torque in response to a FET short. The mitigation system further includes a mitigation-enable module that selectively enables and disables the mitigation module based on a handwheel torque signal. Further, the mitigation system includes a damping module that reduces the motor torque based on a motor velocity signal for the motor.

Abstract: A system for sensor fusion for autonomous driving transition control includes a sensor fusion module and a decision making module. The sensor fusion module fuses a plurality of steering sensor data from one or more sensors of a steering system with a plurality of driver state data from a plurality of driver state sensors as a plurality of fused state data aligned in time. The decision making module determines whether to transition from an autonomous driving mode to a manual driving mode based on the fused state data.

Abstract: A method of mitigating abnormalities in a first control command for controlling a power steering system is provided. The method generates a range signal indicative of a range of command values based on a plurality of input signals. The method determines whether the first control command is out of the range for longer than a predetermined duration of time. The method limits the first control command to the range and sends the limited first control command to the power steering system in response to determining that the first control command is out of the range for shorter than or equal to the duration of time.
