Abstract: The braking control device includes a control amount derivation unit that derives a target vehicle braking force representing a target value of a vehicle braking force applied, and a braking control unit that controls a regenerative braking device and a frictional braking device based on the target vehicle braking force. When the target vehicle braking force is increased, the braking control unit executes a braking force application process of increasing the frictional braking force applied to the wheel so that such frictional braking force becomes larger than the regenerative braking force applied to the wheel. When the target vehicle braking force is increased, the braking control unit executes a switching process of switching at least a part of the frictional braking force applied to the wheel to the regenerative braking force to increase the regenerative braking force applied to the wheel after execution of the braking force application process.

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 vehicle motion manager includes one or more processors configured to: receive a first acceleration request value that requires degeneration and a second acceleration request value that does not require the degeneration from a first application and a second application, respectively; select a smallest acceleration request value out of the acceleration request values received by the one or more processors; when the one or more processors select the first acceleration request value, repeatedly output a degeneration value based on the first acceleration request value; and output an instruction value corresponding to the acceleration request value selected by the one or more processors or the degeneration value to an actuator of a vehicle. The one or more processors are configured to, in response to selection of the first acceleration request value, receive the degeneration value output by the one or more processors instead of the first acceleration request value.

Abstract: During a normal condition of a braking control device, a first instruction unit gives instructions of braking force to be applied to a first wheel and a third wheel, and a second instruction unit gives instructions of braking force to be applied to a second wheel and a fourth wheel. When a failure occurs in the first instruction unit and the first instruction unit can no longer give the instructions of the braking force to be applied to the first wheel and the third wheel, the second instruction unit takes over the task of giving the instruction of braking force to be applied to the first wheel, and a third instruction unit takes over the task of giving the instruction of braking force to be applied to the third wheel.
