Abstract: A control apparatus for a moving body generates a trajectory plan that is a plan indicating a lateral position of the moving body at each point when the moving body is caused to travel along a predetermined route. The control apparatus generates a speed plan that is a plan indicating a traveling speed of the moving body at each point when the moving body is caused to travel along the route. The control apparatus causes the moving body to travel based on both the trajectory plan and the speed plan. The control apparatus generates the speed plan as a plan for causing the moving body to travel based on the trajectory plan after the the trajectory plan is generated.

Abstract: A brake control device includes a processor that controls a brake device of a vehicle. The processor receives a first braking request indicating first braking force by the brake device which is requested from an application that implements a driver assistance function of the vehicle. The processor receives a second braking request indicating second braking force by the brake device which is requested depending on an operation amount of a brake pedal of the vehicle. The processor starts override control when the processor receives the second braking request while the processor controls the brake device in accordance with the first braking request.

Abstract: A controller computes availability of the vehicle that indicates a range reachable by the vehicle by actuation of the actuator and generates a first travel route within a range of the availability of the vehicle, as a travel route followed by the vehicle, when the vehicle travels along a road ahead of the vehicle from a present position. When the road includes a curve and the first travel route cannot be generated within the availability range, the controller sets a target position to a position in the road located before the curve and generates a second travel route within the availability range, as the travel route followed by the vehicle, to stop the vehicle at the target position.

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: 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 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: 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.
