VEHICLE POSITION CONTROL METHOD AND VEHICLE POSITION CONTROL DEVICE FOR CORRECTING POSITION IN DRIVE-ASSISTED VEHICLE

A vehicle position correction device is provided with a controller for correcting a position error of an autonomous host vehicle. The controller detects a lane boundary of a lane in which the host vehicle travels. The controller calculates a target value for a lateral correction amount of the target route by comparing positional relationships between lane boundary detection results and the target route on a map, and changes a lateral movement speed of the target route to calculate the target value for the lateral correction amount according to a bearing of the host vehicle in which the bearing being a vehicle attitude angle. The controller corrects the target route by moving the target route sideways in a lateral direction by an amount equal to the lateral correction amount upon the calculation of the lateral correction amount.
