A method for controlling autonomous driving in an autonomous vehicle includes detecting a situation in which autonomous driving is impossible while the vehicle operates in an autonomous driving mode, outputting a control-right handover request warning alarm and then activating a minimal risk maneuver driving mode, determining a human driver gaze validity based on the detected situation, determining a human driver intervention validity upon determination that the human driver gaze is valid, and determining control-right handover of the autonomous vehicle based on the human driver intervention validity. Thus, the control-right may be reliably transferred from a system to a human driver.

Disclosed embodiments include systems, vehicles, and computer-implemented methods to adjust a threshold level of force to be applied to a steering wheel to disengage an autosteering system. In an illustrative embodiment, a system includes a computing device operably coupled with a vehicle that includes a processor and a computer-readable media configured to store computer-executable instructions configured to cause the processor to: detect that an autosteering system of the vehicle is engaged; detect a level of force applied by an operator to a steering wheel of the vehicle; and disengage the autosteering system when the level of force surpasses a threshold chosen from a default threshold and an adjusted threshold, wherein the adjusted threshold is applied upon detecting a predetermined condition..

Surrounding situation information of a vehicle is acquired. A steering torque applied by using a steering mechanism of the vehicle is detected. A steering angle and a steering direction of the vehicle are detected. Traveling control involving steering assist control is executed based on those pieces of information. In a case where a steering torque amount or the steering angle is detected, a new target lane keeping traveling path or a predetermined target lane departure prevention traveling path of the vehicle is created based on the steering torque amount, the steering angle, and the steering direction of the vehicle. In a case where the steering torque amount or the steering angle is detected again within a predetermined period, the new target lane keeping traveling path or the predetermined target lane departure prevention traveling path is set and traveling control is executed along the set traveling path.

A vehicle is capable of disabling autonomous driving by identifying whether an intervention of a user has occurred during autonomous driving. The vehicle includes a steering wheel, a first sensor device configured to detect a steering torque of the steering wheel, a steering angle of the steering wheel, and a steering angular velocity of the steering wheel, and a second sensor device configured to detect a touch of a user applied to the steering wheel. When the vehicle travels in an emergency control state in which a deceleration/acceleration speed of the vehicle is greater than a predetermined first value during autonomous driving, if the touch of the user on the steering wheel is detected through the second sensor device, the emergency control state is disabled under certain conditions, and if the steering torque is greater than or equal to a predetermined torque value, autonomous driving is disabled.

In a vehicle control device, a switching hyperplane generation unit generates a switching hyperplane based on a travel state of a vehicle and cornering stiffness dependent on a travel surface state as a state of a road surface on which the vehicle travels. A deviation computation unit calculates a deviation between a target trajectory and an actual trajectory of the vehicle. A state estimation unit estimates a state to be controlled of the vehicle based on the deviation calculated by the deviation computation unit. A target steering angle and acceleration/deceleration computation unit calculates a target steering angle and a target acceleration/deceleration rate of the vehicle based on the switching hyperplane generated by the switching hyperplane generation unit and an estimated state as the state estimated by the state estimation unit.
