An apparatus includes a control unit for a vehicle that is equipped to cause automatic interventions in the longitudinal and/or lateral control of the vehicle. The control unit is configured to determine reaction information relating to a reaction of a user of the vehicle to at least one automatic intervention of the vehicle. The control unit is also configured to adjust least one operating parameter of the vehicle, which has an influence on automatic interventions in the longitudinal and/or lateral control of the vehicle, depending on the reaction information.

Provided is a control apparatus for a vehicle configured to perform steering assist control and driving support control based on a motor control amount, the control apparatus being further configured to correct the motor control amount such that a specific steering amount in a second period becomes smaller than that in a first period, the specific steering amount being an amount of change in a steering angle required for a magnitude of a steering torque to reach a torque threshold, the first period being a period from a first time point at which a driving support operation state is changed to an on state to a second time point at which a driving operation switching request is issued, and the second period being a period from the second time point to a third time point at which the driving support operation state is changed to an off state.

An apparatus for controlling an MDPS system may include: a column torque sensor configured to sense column torque applied to a steering column of a vehicle; a vehicle velocity sensor configured to sense vehicle velocity of the vehicle; an MDPS basic logic unit configured to decide a first assist command current for driving an MDPS motor in a manual driving mode of a driver; an autonomous driving control unit configured to decide a second assist command current for driving the MDPS motor in an autonomous driving mode of the vehicle; and a mode switching control unit configured to decide a weight into which the driver's steering intention is reflected, and apply the decided weight to the first and second assist command currents to decide a final assist command current for driving the MDPS motor when the vehicle is switched from the autonomous driving mode to the manual driving mode.

An electric steering apparatus may include: a column torque sensor configured to detect column torque; a vehicle speed sensor configured to detect vehicle speed of the vehicle; an autonomous driving control unit configured to determine a second command current in an autonomous driving mode; a driver steering intervention determination unit configured to determine whether a driver intervenes in steering; an MDPS logic unit configured to determine a first command current based on the column torque and the vehicle speed, when the driver's steering intervention occurs in the autonomous driving mode; and an output control unit configured to determine a final weight based on a steering angular velocity and the column torque, when the driver's steering intervention occurs in the autonomous driving mode, and determine a final command current by applying the determined final weight to the first and second command currents.

The present disclosure provides for a steering control method and a steering control system for self-driving of a vehicle. The method comprises the steps of: obtaining information about an expected steering angle of a vehicle based on an automatic planning control operation; detecting whether an effective torque is applied to a steering wheel by a driver; and when it is detected that the driver has applied the effective torque to the steering wheel, computing a difference between a turning angle of the steering wheel controlled by the driver and the expected steering angle of a vehicle, and determining a self-driving intent prompt torque according to the difference between the two, wherein the self-driving intent prompt torque is to be applied to a steering system.

A steering system includes a reaction drive apparatus to apply a reaction force to a steering member, a steering operation drive apparatus to turn steered wheels, a movement drive apparatus to move the steering member between an operation position and a retraction position, a mode switching circuit to switch a manual driving mode and an automatic driving mode, a movement control circuit to move the steering member to the operation position when switched to the manual driving mode, and to move the steering member to the retraction position when switched to the automatic driving mode, a reaction control circuit to control the reaction drive apparatus in the manual driving mode based on steering information of the steering member and steering operation information of the steering operation drive apparatus, and an actuation restriction circuit to restrict actuation of the steering member in the automatic driving mode.

A computer includes a processor and a memory storing instructions executable by the processor to input steering torque data and steering wheel angle data to a machine learning program trained to output a status of a hand of an occupant relative to a steering wheel, the status being one of (1) the hand is on the steering wheel, (2) the hand is off the steering wheel and no weight is applied to the steering wheel, or (3) the hand is off the steering wheel and a weight is applied to the steering wheel, and actuate a steering subsystem when the output of the machine learning program indicates that the hand of the occupant is off the steering wheel.

A vehicle traveling controller according to the present disclosure performs automatic steering so that a vehicle travels along a target path. The vehicle traveling controller allows a driver to intervene in steering. When the driver intervenes in steering and thereby a traveling position of the vehicle deviates outside from a threshold line set apart from the target path in a lane width direction, the vehicle traveling controller increases a steering reaction force acting on steering operation by the driver.

A vehicle system includes a steering wheel configured to output an output based on an input from a user, and a controller configured to: determine a target orientation of front wheels of a vehicle based on vehicle environment information, determine whether an orientation of the front wheels of the vehicle based on the output from the steering wheel deviates from the target orientation, disengage the steering wheel from the front wheels in response to determination that the orientation of the front wheels deviates from the target orientation, adjust the orientation of the front wheels to the target orientation and provide a feedback in response to adjusting the orientation of the front wheels to the target orientation.

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.
