Vehicle alert device

Vehicle alert device

A vehicle alert device (10) executes alert control of determining, when a target is detected in a periphery of an own vehicle (C1), 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...

description A vehicle alert device (10) executes alert control of determining, when a target is detected in a periphery of an own vehicle (C1), 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.
