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 jackknife suppression device is configured to execute an acquisition process, a prediction process, a determination process, and a treatment process. The acquisition process is a process of acquiring a hitch angle variable and a steered angle variable. The prediction process is a process of calculating a predicted value of the hitch angle using the hitch angle variable and the steered angle variable as inputs. The determination process is a process of determining whether there is a high risk that a jackknife occurs using the predicted value and the steered angle variable as inputs. The treatment process is a process of operating predetermined hardware in order to suppress occurrence of the jackknife when it is determined that the risk is high.

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 motion manager includes one or more processors configured to: receive a stop holding request for keeping a vehicle in a stopped state as one of motion requests from application software; and output an instruction value for turning ON a hydraulic brake to the hydraulic brake on a condition that the stop holding request is received. The one or more processors are configured to continue outputting the instruction value to a parking brake regardless of a presence or absence of the stop holding request, when outputting an instruction value for turning ON a parking brake to the parking brake after starting outputting the instruction value and until switching of the parking brake to an ON state is completed.

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 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.
