PROBLEM TO BE SOLVED: To provide an electrically-driven transport vehicle that suppresses use frequency of a mechanical brake.SOLUTION: There is provided an electrically-driven mining vehicle 100 equipped with a regenerative braking device and a mechanical braking device. The electrically-driven mining vehicle comprises: an obstruction detector 106; a speed detector 108 that detects the travelling speed of the electrically-driven mining vehicle; an alarm that emits a first alert for prompting the operator of the electrically-driven mining vehicle to operate a regenerative brake pedal that only operates the regenerative braking device only, and a second alert for prompting the operator to operate a blended braking pedal that uses both the regenerative braking device and the mechanical braking device; and a vehicle control device 4 for controlling the output of the alarm. If the travelling speed of the electrically-driven mining vehicle is within a low-speed threshold value which is for determining a low-speed region and in which there is not considered to be any difference in distance between a first braking distance that is the braking distance obtained when only the regenerative braking device is operated through the operation of the regenerative braking pedal and a second braking distance that is the braking distance obtained when the blended braking device is operated, an output signal of the first alert is to be output earlier than an output signal of the second alert by an alert interval time or longer.SELECTED DRAWING: Figure 3
【課題】機械ブレーキの使用頻度を控える電気駆動運搬車両を提供する。【解決手段】電気駆動鉱山車両100は、回生ブレーキ装置及び機械ブレーキ装置を搭載し、障害物検出器106と、自車の走行速度を検出する速度検出器108と、自車のオペレータに対して回生ブレーキ装置のみの操作を促す第1の警告、及び回生ブレーキ装置及び機械ブレーキ装置を併用する協調ブレーキペダルの操作を促す第2の警告を出力する警報器と、警告の出力制御を行う車両制御装置4とを備える。自車の走行速度が、回生ブレーキ装置のみを回生ブレーキペダル操作により作動させた際の制動距離である第1制動距離、及び協調ブレーキを作動させた際の制動距離である第2制動距離の距離差がないと見做せる低速域を判定するための低速度閾値以下の場合は、第1の警告の出力信号を第2の警告の出力信号よりも警告間隔時間以上早く出力する。【選択図】図3
