VEHICLE TRAVEL TRAJECTORY CONTROL DEVICE

摘要

Provided is a travel trajectory control device with which a vehicle travel trajectory control is carried out by computing a target steering angle (thetalkat) corresponding to a target steering angle of the front wheels for making a vehicle (12) travel to track a target trajectory (S100), and controlling the steering of the front wheels on the basis of the target steering angle (thetalkat) with a steering variation device (30) and a power steering device (22) (S700). The driving ability of a driver and/or a trajectory change intent thereof are determined (S400). On the basis of a driving ability index value (Iskill) and/or an index value which denotes the intensity of the intent of the trajectory change of the driver (Iwill), the tracking of the vehicle to the target trajectory is variably set by variably setting the gain in the travel trajectory control (S500).
