DRIVING SUPPORT DEVICE

A driving support device performs steering control and deceleration control for avoiding an object which is detected in front of a host vehicle. The driving support device performs: calculating a target lateral distance which is a target of the steering control and which is a lateral distance between the host vehicle and the object when the host vehicle passes by the object; and increasing target deceleration which is a target of the deceleration control and which is deceleration of the host vehicle when the host vehicle passes by the object as a lateral distance restraint value which is obtained by subtracting the target lateral distance from a threshold value increases when the target lateral distance is less than the threshold value.
