METHOD FOR CONTROLLING MANUAL DRIVING MODE OF AUTONOMOUS VEHICLE
A method for controlling a manual driving mode includes manual mode detecting step detecting whether a vehicle switched from autonomous to manual mode; first step controlling angle of tire and steering angle of a steering wheel using travel route information when switching to manual mode is detected; delay time determination step determining a delay time of change of the angle of the tire with change of the steering angle of the steering wheel by the change in the angle of the tire with the change in the steering angle of the steering wheel for predetermined time; delay time comparison step comparing the determined delay time with predetermined time period; second step controlling only the steering angle of the steering wheel using travel route information when delay time is within the predetermined time period; and third step controlling angle of the tire by steering angle of the steering wheel.
ADAPTIVE DYNAMIC MODEL FOR AUTOMATED VEHICLE
An operating system for an automated vehicle includes a failure-detector and a controller. The failure-detector detects a component-failure on a host-vehicle. Examples of the component-failure include a flat-tire and engine trouble that reduces engine-power. The controller operates the host-vehicle based on a dynamic-model. The dynamic-model is varied based on the component-failure detected by the failure-detector.
Work vehicle
A work vehicle includes: a body; a traveling apparatus capable of a turning travel; a speed detector capable of detecting a vehicle speed; a steering tool manually operable to steer the traveling apparatus; a notification apparatus; and a controller. The controller is configured or programmed to control the traveling apparatus in response to a manual operation, with use of a travel control module; determine, based on a relationship between the vehicle speed and a steering angle of the steering tool, whether at least one of the vehicle speed and the steering angle needs to be reduced, with use of a determination module; and control the notification apparatus to give a notification of the determination by the determination module, with use of a notification module.

DRIVING ASSIST APPARATUS
In a driving assist apparatus for assisting a lane change from an own lane to a target lane, when a post-smoothing probability obtained by smoothing a time course change in a lane presence possibility which increases with the possibility that a target is another vehicle traveling in the target lane (target lane other vehicle) is greater than a threshold value, that target can be extracted as the target lane other vehicle. The post-smoothing probability requires some length of time to coincide with the lane presence possibility. Therefore, if after completion of a lane change, another lane change is immediately started in the same direction, there arises a possibility that the target lane other vehicle cannot be extracted properly. Therefore, in the case where after completion of a lane change, another lane change is started in the same direction, the lane change is not started until a re-change prohibition time elapses.
LANE CHANGE ASSIST DEVICE
A first limiter limits a first target steering angle correspondence value by a first steering angle correspondence value guard which defines the upper limit value of the steering angle correspondence value and is larger than a steering angle correspondence value guard at lane change time and limits a first target steering angular velocity correspondence value by a first steering angular velocity correspondence value guard which defines the upper limit value of the steering angular velocity correspondence value and is larger than a steering angular velocity correspondence value guard at lane change time. An actuator controller for first yaw angle return control which is configured to control an actuator to operate a steering wheel so that steering angle correspondence value becomes a first target steering angle correspondence value and a steering angular velocity correspondence value becomes a first target steering angular velocity correspondence value.
