Abstract: In a control apparatus, upon determination that an obstacle has a collision possibility, an operation determiner determines to instruct a notification system to issue, to an occupant, a notification related to the collision possibility with the obstacle. The operation determiner determines whether a collision-avoidance operation has been carried out by the occupant since the issuance of the notification. The operation determiner determines not to instruct the vehicle motion control system to execute a collision-avoidance assistance operation upon determination that (i) no collision-avoidance operations have been carried out by the occupant since the issuance of the notification and (ii) the obstacle having the collision possibility is a low-height object, the low-height object being defined as an object that has fallen on a road and has a height that is sufficiently low that the vehicle is enabled to pass over the obstacle.

Abstract: A zero point estimation device is configured to perform a first acquisition process, a second acquisition process, and a zero point estimation process. The first acquisition process is a process of acquiring a plurality of first detection values of a first sensor sampled at different timings from each other while a vehicle is traveling with a change in a direction of travel. The second acquisition process is a process of acquiring a plurality of second detection values of a second sensor sampled in synchronization with the sampling timings of the first detection values to be acquired by the first acquisition process. The zero point estimation process is a process of estimating a zero point of the second sensor by using, as inputs, the plurality of first detection values acquired by the first acquisition process and the plurality of second detection values acquired by the second acquisition process.

Abstract: A vehicle control device to be applied to a vehicle including parking brakes provided in association with right and left wheels and configured to be driven to bring the wheels into a non-rotatable state includes a processor. The processor is configured to acquire abnormality occurrence information on each of the right and left parking brakes. The processor is configured to, when an abnormality condition that a drive command is output to each of the parking brakes and one of the parking brakes has an abnormality is satisfied, control a device other than the parking brakes in the vehicle to suppress rotation of the wheel provided with the parking brake having the abnormality.

Abstract: A vehicle includes a sideslip preventing function of preventing a sideslip of the vehicle by separately adjusting a longitudinal force applied to each of the wheels. A controller controls the vehicle based on requests input from a driver assistance device, thereby causing the vehicle to travel autonomously. The controller calculates wheel lateral force request values based on the requests input from the driver assistance device. The wheel lateral force request values are request values of lateral forces acting on the respective wheels. The controller, when a behavior of the vehicle is in an oversteer state in a case in which the sideslip preventing function is failing, limits the wheel lateral force request values for the front wheels to values less than or equal to a first lateral force limit value, which is a limit value of the lateral force that can act on the rear wheels.

Abstract: A vehicle travel control apparatus includes an information acquiring section; a determining section that determines whether a special road terrain exists; and a speed control section that controls a speed of the subject vehicle. The speed control section is further configured to: when the special road terrain exists but a preceding vehicle does not exist, increase or decrease the speed of the subject vehicle with respect to a pre-set vehicle speed in the energy efficiency zone such that the energy efficiency is improved; and when the special road terrain and a preceding vehicle exists and the speed of the subject vehicle is planned to increase in the energy efficiency zone, control the speed of the subject vehicle in an inter-vehicle distance maintenance zone such that the subject vehicle has an inter-vehicle distance to the preceding vehicle longer than a pre-set inter-vehicle distance.

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.
