Operating motor vehicle electrically assisted steering

A motor vehicle has an electrically assisted steering system. A steering angle velocity of the motor vehicle, and a driver manual torque change applied by a driver of the motor vehicle are determined. At least the steering angle velocity and the driver manual torque change are analyzed to determine whether the driver manual torque change and the steering angle velocity are not correlated. An error signal is output if the driver manual torque change and the steering angle velocity are not correlated.

CONTROLLING DRIVING MODES OF SELF-DRIVING VEHICLES

A computer-implemented method, system, and/or computer program product controls a driving mode of a self-driving vehicle (SDV). One or more processors compare a control processor competence level of an on-board SDV control processor in controlling the SDV to a human driver competence level of a human driver in controlling the SDV while the SDV encounters a current roadway condition which is a result of current weather conditions of the roadway on which the SDV is currently traveling. One or more processors then selectively assign control of the SDV to the SDV control processor or to the human driver while the SDV encounters the current roadway condition based on which of the control processor competence level and the human driver competence level is relatively higher to one another.
