Abstract: A method for providing reverse directional polarity steering in a vehicle includes, in response to receiving a reverse position polarity steering mode signal indicating selection of a reverse position polarity steering mode: determining a selected gear of a transmission of the vehicle; determining a vehicle speed; and, in response to a determination that the selected gear includes a reverse gear and the vehicle speed is within a range of a predetermined vehicle speed, selectively controlling at least one roadwheel actuator of the vehicle in a direction opposite to a direction indicated by a handwheel actuator associated with a handwheel of the vehicle.

Abstract: A vehicle steering control method includes receiving a sensed handwheel angle corresponding to a position of a handwheel and receiving a sensed handwheel toque value indicating an amount of torque applied by an operator on the handwheel. The method also includes, in response to a determination that the handwheel motor is in an unlocked condition, generating a roadwheel angle based on the sensed handwheel angle and a vehicle speed. The method also includes, in response to a determination that the handwheel motor is in a locked condition generating the roadwheel angle based on the sensed handwheel torque value and the vehicle speed and, in response to a determination that the locked condition of the handwheel motor is an intermittent condition, maintaining the handwheel motor in the locked condition.

Abstract: Technical solutions are described for providing driver warning using steering systems. An example steering system includes a motor control system that sends a command to a motor. The steering system further includes a fault monitoring system that sets a fault indication flag by monitoring one or more components of the steering system. The steering system further includes a driver warning feedback system that generates a warning injection signal based on and in response to the fault indication flag being set. Further, the motor control system generates a driver feedback by modifying the command to the motor using the warning injection signal, and sending the modified command to the motor.

Abstract: A method includes, in response to an entry signal indicating an opening of an operator door, detecting a first torque value corresponding to a first torque applied to a handwheel and determining a second torque value corresponding to the first torque value. The method also includes applying, to the handwheel, a second torque corresponding to the second torque value and, based on at least one of a measurement associated with a seat sensor and a period associated with the first torque being applied to the handwheel: determining whether to selectively adjust the second torque value; and, in response to a determination to selectively adjust the second torque value, applying, to the handwheel, an adjusted torque corresponding to the adjusted second torque value.
