Abstract: A combination vehicle includes a tractor including a steered wheel and a trailer towed by the tractor A control device for the combination vehicle includes an estimation unit. The estimation unit estimates a length of the trailer based on a mathematical expression obtained by solving, for the length of the trailer, simultaneous equations including an equation of motion for a hitch angle velocity that is a time rate of change in a hitch angle and an equation of motion for a virtual steering angle velocity that is a time rate of change in a virtual steering angle of the trailer. The mathematical expression includes the virtual steering angle velocity as a parameter.

Abstract: A controller for a vehicle is configured to execute a process that detects an anomaly of a steering device and a process that performs an automatic turning control that causes the vehicle to turn automatically along a traveling route. The controller is configured to perform the automatic turning control by controlling the steering device when an anomaly of the steering device is not detected. The controller is configured to, when an anomaly of the steering device is detected, calculate, as a predicted value, a load on the substitute device on an assumption that the automatic turning control is performed by activating the substitute device, and perform the automatic turning control by controlling the substitute device when an allowable range that is a set of values of a load allowable to the substitute device includes the predicted value.

Abstract: An information processing method includes receiving shift requests to control a shift range of a vehicle from a plurality of application software products configured to implement driver assistance functions of the vehicle, arbitrating the shift requests by using, as a condition, whether each of the received shift requests is a request in a traveling range or a request in a parking range, when the traveling range is the shift range in which a driving wheel of the vehicle is rotatable and the parking range is the shift range in which the driving wheel is not rotatable, and generating an instruction value for an action request to drive an actuator based on a result of arbitration.

Abstract: A backward movement control device performs a backward movement control of an articulated vehicle including a tractor that includes steered wheels and a trailer towed by the tractor. The tractor is equipped with a steering control device that executes feedback control for causing a steered angle of the steered wheels of the tractor to follow a target steered angle. The backward movement control device includes a control unit configured to calculate the target steered angle such that a virtual steered angle follows a target virtual steered angle when a backward movement operation of the articulated vehicle is performed. The virtual steered angle is a steered angle of steered wheels that are virtually present in the trailer if the trailer is regarded as a rigid vehicle. The target virtual steered angle is a target value of the virtual steered angle that is set through a specific operation by an operator.

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 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.
