    摘要： An object of the present invention is to provide a vehicle motion control device that generates a travel path capable of realizing comfortable ride comfort and high safety with a small physical quantity related to a vehicle behavior such as a longitudinal acceleration, a lateral acceleration, and a vertical acceleration generated when a vehicle passes or avoids with respect to a predetermined region such as unevenness on a course of a vehicle. Therefore, the vehicle motion control device includes a vehicle behavior prediction portion that predicts a physical quantity related to a vehicle behavior that occurs when a vehicle maintains a reference route toward a predetermined region on a course and a physical quantity related to a vehicle behavior that occurs when the vehicle shifts to an avoidance route for avoiding the predetermined region, and a path generation portion that generates a travel path defined by the reference route or the avoidance route in which the physical quantity is smaller than a defined value.

    摘要： A cruise control system for a motor vehicle. The system includes a setpoint value generator for generating a setpoint value determining the vehicle speed, and an actuating device that controls the speed of the vehicle to a setpoint speed through intervention into the drive and/or braking system. The system automatically adapts the setpoint speed to a predicted roadway curvature. The setpoint value generator includes at least two modules working independently from one another, including a base module for generating a base setpoint value and a curve module for generating a curve setpoint value that represents a maximum speed at which a curve having a given curvature may be negotiated without exceeding a predefined limiting value for the lateral acceleration of the vehicle, and includes a fusion module that forms a final setpoint value for the actuating device from the base setpoint value and the curve setpoint value through minimum selection.

    摘要： In an abnormality determination device for determining presence or absence of an abnormality of a 6-axis inertial measurement sensor installed in a vehicle to detect a forward-backward acceleration, a lateral acceleration, a vertical acceleration, a roll rate, a pitch rate, and a yaw rate of the vehicle, the abnormality determination device includes: a 3-axis inertial measurement sensor that detects the forward-backward acceleration, the lateral acceleration, and the yaw rate; and an abnormality determination unit that determines presence or absence of an abnormality of the 6-axis inertial measurement sensor, wherein the abnormality determination unit determines the presence or absence of an abnormality of the 6-axis inertial measurement sensor by comparing the forward-backward acceleration, the lateral acceleration, and the yaw rate acquired by the 6-axis inertial measurement sensor with the forward-backward acceleration, the lateral acceleration, and the yaw rate acquired by the 3-axis inertial measurement sensor, respectively.

    摘要： A system according to the present disclosure includes an actuator control module and a damping ratio module. The actuator control module is configured to control an actuator of a vehicle to cause the vehicle to perform a yaw maneuver by rotating about its yaw axis. The damping ratio module is configured to determine a damping ratio based on an operating parameter measured during the yaw maneuver. The operating parameter includes at least one of a yaw rate of the vehicle, a yaw rate of a trailer connected to the vehicle, a lateral acceleration of the vehicle, a lateral acceleration of the trailer, a heading angle of the vehicle, and a hitch angle between a longitudinal axis of the vehicle and a longitudinal axis of the trailer.

    摘要： A vehicle occupant assistance apparatus predicts acceleration occurring when a vehicle is traveling. When a make-up mode is activated, assistance information is notified before a predetermined value of the acceleration occurs, based on predicted values of the acceleration. Thus, since the assistance information is notified to an occupant before the vehicle shakes due to the predetermined value of the acceleration, assistance taking a shake of the vehicle into consideration can be rendered to the occupant who applies make-up when the vehicle is traveling.
