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.

Systems and methods for vehicle ingress or egress assist

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.

Torque-based directional control in steer-by-wire steering systems

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.
