Abstract
In a vehicle steering assist device that includes an electric power steering device that generates a control torque that modifies a return torque for urging a steering wheel to a neutral position, a steering assist ECU that controls the control torque, and a surrounding information detecting device (camera sensor, radar sensor) that detects at least information in front of a vehicle, the control torque is controlled such that a ratio of a change amount of the modified return torque to a change amount of a steering operation amount at the start of avoidance steering decreases when an obstacle is detected in front of the vehicle by the surrounding information detecting device and the avoidance steering for the vehicle to avoid collision with the obstacle is determined to be required.
