Abstract: A turning controller for a vehicle is configured to execute: a time obtaining process that obtains collision prediction time; a lateral movement amount determining process that determines whether a target lateral movement amount is greater than or equal to a lateral movement amount determination value; and an automatic turning process that, in a case in which the collision prediction time is shorter than or equal to a determination prediction time, outputs a command for steering the front wheel to the front wheel steering device and outputs a command for steering the rear wheel to the rear wheel steering device, in order to avoid a collision between the vehicle and the obstacle; a counter-phase process in the automatic turning process in a case in which the target lateral movement amount is determined to be greater than or equal to the lateral movement amount determination value.

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 turn assist device is configured to execute a turn assist process that assists turning of a vehicle in a case in which a steering operation of a steering wheel is in progress in a situation in which collision prediction time is shorter than or equal to determination prediction time. The turn assist process includes: an in-phase process that outputs a command for steering a rear wheel in the same direction as a steering direction of a front wheel, and a counter-phase process that outputs a command for steering the rear wheel in a direction opposite to the steering direction of the front wheel when a difference between an actual value of the lateral acceleration of the vehicle and a lateral acceleration target value exceeds a difference determination value during execution of the in-phase process.

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: In a surroundings monitoring device for a vehicle to which a towed vehicle is attachable, a turn information acquisition unit is configured to, when a subject vehicle is turning with the towed vehicle attached to a rear of the subject vehicle, acquire turn information related to the subject vehicle and the towed vehicle. A zone setting unit is configured to set warning zones to left and right, behind the subject vehicle, and extend, based on the turn information acquired, the warning zones further rearward when the towed vehicle is attached to the rear of the subject vehicle than when there is no towed vehicle attached. A control unit is configured to, when an object is detected by a detection device in any of the warning zones set by the zone setting unit, trigger a collision-inhibiting operation for inhibiting a collision with the object to be performed.
