The invention discloses a vehicle distance detection alarm which comprises a controller. The controller is electrically connected with a laser ranging sensor, a voice alarm and a vehicle speed detection unit capable of detecting in realtime when current vehicle speed is larger than or equal to 60Km/h respectively, and the controller comprises a time setting module, a safety distance setting module, a comparison module and an execution module. When the vehicle speed is larger than or equal to 60Km/h, the controller calculates corresponding safety vehicle distance according the vehicle speed, compares the safety vehicle distance with vehicle distance state detected by the laser ranging sensor to judge whether the current vehicle distance is out of the safety vehicle distance or not and starts the voice alarm when the current vehicle distance is smaller than the safety vehicle distance for alarming to prompt a driver to take corresponding measures in advance to avoid safety accidents.
