Title:
TRAVEL CONTROL DEVICE OF VEHICLE
Document Type and Number:
Japanese Patent JP2020090215
Kind Code:
A
Abstract:
To properly transmit a control intention on a system side to a driver when correcting positional deviation of an own vehicle from a target course, correct the positional deviation without giving discomfort, and accurately make the driver follow the target course.SOLUTION: A steering control section 50b calculates a target steering angle to travel an own vehicle along a target course. A braking/driving force control section 50c calculates a target yaw moment to correct positional deviation from the target course of the own vehicle. A control ratio setting section 50d sets a control ratio of cooperative control by steering control and yaw moment control on the basis of deviation amount of a lateral position from the target course of the own vehicle. The control ratio is set to reduce a ratio occupied by the steering control and make the yaw moment control main when the positional deviation of the own vehicle from the target course is relatively small, and is set to make the ratio occupied by the steering control large when the positional deviation of the own vehicle from the target course is relatively large.SELECTED DRAWING: Figure 2
