A braking distance control device employed for an electrically driven work vehicle includes a safety vehicle speed calculation unit 9 that calculates a safety vehicle speed at which a braking distance provided by use of an electric brake device becomes less than or equal to a threshold value, based on gradient information, payload information, road surface friction information, vehicle speed information, and a braking torque characteristic of electric motors. Preferably, the braking distance control device includes: a critical vehicle speed for deceleration calculation unit 5 that calculates a critical vehicle speed for deceleration at which deceleration provided by use of the electric brake device becomes less than or equal to a threshold value; a vehicle speed judgment unit 8 that judges whether the work vehicle can be stopped within a set distance by the electric brake device, based on result of comparing the vehicle speed information with the safety vehicle speed and the critical vehicle speed for deceleration; a notification command unit 17 that calls the operator's attention or prompts a brake operation, based on the result of the judgment; an operation judgment unit 14 that judges a setting of notification, based on pedal operation amounts; and a logical product calculation unit 15 that outputs a setting of a notification operation, based on result of the judgments by the vehicle speed judgment unit 8 and the operation judgment unit 14.
