A vehicle alert device () executes alert control of determining, when a target is detected in a periphery of an own vehicle (C), within a set calculation period, whether the target is an alert-target object that does not include a stationary object, determining, when the target is an alert-target object, whether the alert-target object exists in a blind spot area (RL, RR) of a driver, and alerting the driver when the alert-target object exists in the blind spot area. The vehicle alert device avoids executing the alert control when a relative speed of the own vehicle with respect to the alert-target object at a time when the own vehicle overtakes the alert-target object is equal to or higher than a predetermined threshold value. The vehicle alert device sets the predetermined threshold value to a larger value and sets the set calculation period to a shorter value, when a travel speed of the own vehicle at the time when the own vehicle overtakes the alert-target object is equal to or higher than a predetermined speed, than the predetermined threshold value and the set calculation period at a time when the travel speed of the own vehicle is lower than the predetermined speed.

A driving supporter includes: a departure-possibility-value obtainer that obtains a departure-possibility value; a relative positional relationship obtainer that detects another vehicle located diagonally at a rear of an own vehicle and obtain a relative positional relationship between them; a support executer that executes a lane-departure prevention support; and a support controller that controls the support executer to execute the lane-departure prevention support when the departure-possibility value is greater than or equal to a threshold value. The support controller includes a threshold-value determiner that determines the threshold value to a smaller value when the relative positional relationship is a set relationship than when the relative positional relationship is not the set relationship. The set relationship is a relationship in which there is a possibility of collision of the own vehicle with the other vehicle in an event of departure of the own vehicle from a lane.
