1. A vehicle driving support device including a control device that executes lane deviation suppression control in which an own vehicle is autonomously steered to suppress the own vehicle from deviating from a lane, wherein the control device is configured to
execute the lane deviation suppression control when there is a possibility that the own vehicle deviates from the lane and when an execution prohibition condition is not satisfied, the execution prohibition condition being a condition for prohibiting execution of the lane deviation suppression control based on a steering operation by a driver of the own vehicle,
execute the lane deviation suppression control so as to steer the own vehicle such that a behavior parameter representing a behavior of the own vehicle during the execution of the lane deviation suppression control does not exceed a behavior parameter upper limit value, and
reduce the behavior parameter upper limit value or change the execution prohibition condition such that the execution prohibition condition is not unlikely to be satisfied when the own vehicle is traveling at a speed equal to or lower than a predetermined speed, compared to when the own vehicle is traveling at a speed higher than the predetermined speed.
