摘要： Provided are a vehicle motion control device, a method thereof, a program thereof, a system thereof in which it is adapted for traveling situation while an occurrence of an unstable behavior of a vehicle at the time of automatic lane change is suppressed, and a target trajectory generation device, a method thereof, a method thereof, a program thereof, and a system thereof. In a vehicle that can automatically control a lateral acceleration generated in the vehicle at the time of lane change, the lateral acceleration at the time of lane change is controlled such that an absolute value of a maximum lateral acceleration generated on a lateral acceleration generation phase (the secondary steering side) in a lateral direction opposite to the moving direction at the time of lane change is equal or more than an absolute value of a maximum lateral acceleration generated on a lateral acceleration generation phase (primary steering side) in the same direction as a lateral moving direction at the time of lane change.

摘要： Provided are: a device and a method for controlling vehicle movement, with which it is possible to suppress causing uncomfortableness to vehicle occupants and causing unstable behavior during turning by automatic travel control; and a device and a method for generating a target course. In a vehicle capable of automatically controlling lateral acceleration occurring in the vehicle, the present invention controls the acceleration occurring in the vehicle such that jerk, which is the change over time of acceleration, becomes the greatest in a region where the lateral acceleration that occurs upon entering a curve is equal to or less than half the acceleration during normal turning, and the jerk decreases as the acceleration increases.

摘要： It is an object of the present invention to provide a power steering apparatus control device in which it is possible to suppress generation of the canceling of the automatic steering unintended by the driver.The present invention provides a control device controlling the operation of a power steering apparatus in which there is selected either an assist control (28) in which a steering force is assisted based on a steering torque input through the operation of a steering wheel or an automatic steering control (29) in which a steering angle of a turning wheel is controlled based on a steering angle command value. When, in the state in which the automatic steering control (29) is selected, the steering torque exceeds a predetermined threshold value, the automatic steering control (29) is canceled and the assist control (28) is selected. There is set a steering angle velocity command value in accordance with an increase amount of the steering torque due to the turning based on the automatic steering control (29), whereby there is performed a canceling suppression control in which canceling of the automatic steering control (28) is suppressed.
