Abstract: A travel controller recognizes an action of a driver of a vehicle from image data of the driver. The travel controller obtains information indicating that determination of whether autonomous driving of the vehicle is permissible cannot be given. When the information indicating that determination of whether the autonomous driving of the vehicle is permissible cannot be given is obtained, the travel controller operates a human interface to request the driver for an instruction to drive the vehicle. The travel controller determines whether the driver is giving an instruction to drive the vehicle from an action of the driver recognized in response to the request for an instruction to drive the vehicle. When determined in the determination process that the driver is giving an instruction to drive the vehicle, the travel controller operates a drive system of the vehicle to permit autonomous driving of the vehicle.

Abstract: A control device includes a model generation unit that generates a control model that formulates a task to be executed, and a task processing unit that causes the vehicle to execute the task by performing model prediction control using the control model. Assuming that a first state space is a state space of the control model used at an execution time of the first task, and a second state space is a state space of the control model used at an execution time of the second task, the task processing unit starts to cause the vehicle to execute the second task, after executing a transition process that is a process of making a value of a state variable that is commonly included in both the first state space and the second state space within a predetermined range that is allowed at the execution time of the second task.

Abstract: A vehicle includes vehicle devices configured to adjust a lateral movement amount of the vehicle, and a steering wheel lock mechanism. The vehicle devices include a front-wheel steering device and a remaining device that is a device other than the front-wheel steering device. When there is an anomaly in the front-wheel steering device, a vehicle control device switches a state of the steering wheel lock mechanism from a deactivated state to an activated state. The control device adjusts the amount of lateral movement of the vehicle by activating the remaining device when rotation of the steering wheel is disabled.

Abstract: A control device for a vehicle includes one or more processors configured to: perform feedback control on an acceleration of the vehicle by controlling a driving force of an internal combustion engine mounted on the vehicle based on a difference between a requested acceleration of the vehicle from an application and an actual acceleration of the vehicle; calculate a first predicted acceleration that is a predicted acceleration of the vehicle on an assumption that the internal combustion engine is controlled into a fuel-cut state; and control the internal combustion engine into the fuel-cut state without performing the feedback control when a coasting condition that is predetermined is satisfied and the first predicted acceleration is equal to or higher than a lower limit value that is predetermined as a negative value.

Abstract: A vehicle automatically gets out of a parking area toward a location required by an user. A relative position between a communication terminal carried by the user and the vehicle is determined according to one of detection processes corresponding to a communication state between the communication terminal and one or more of sensor units on the vehicle. An out-of-parking target position is set based on a detection result of the position detection, and an optimum out-of-parking target position is calculated by updating the out-of-parking target position when the position detection has a higher reliability than the currently set out-of-parking target position while getting out of the parking area. An autonomous driving operation of the vehicle is controlled to get out of the parking area toward the out-of-parking target position.
