PROBLEM TO BE SOLVED: To suppress an amount of consumption of urea water during automatic driving of a vehicle.SOLUTION: A vehicle automatic drive device comprises a drive schedule generation unit (14) that generates a plurality of vehicle driving courses indicative of a timewise change in speed of an own vehicle and travelling direction thereof on the basis of surrounding information on the own vehicle detected by an external sensor (1) and map information stored in a storage device (5). A drive area (NM) of an engine in which an amount of NOper a unit time from the engine is equal to or more than a predetermined amount thereof is preliminarily stored. When a drive state of the engine is not within the drive area (NM), if it is discriminated that an amount of urea water in a urea water tank (72) is equal to or less than a predetermined amount thereof, the drive schedule generation unit (14) is configured to determine the vehicle driving course in which the drive state of the engine does not enter in the drive area (NM) of the engine as a target driving course from the plurality of vehicle driving courses generated by the drive schedule generation unit (14).SELECTED DRAWING: Figure 18
【課題】車両の自動走行中おける尿素水の消費量を抑制する。【解決手段】外部センサ(1)により検出された自車両の周辺情報および記憶装置(5)に記憶された地図情報に基づいて、自車両の速度および進行方向の時間的変化を示す複数の車両走行進路を生成する走行計画生成部(14)を具備する。機関からの単位時間当たりのNOX排出量が予め定められた量以上となる機関の運転領域(NM)が予め記憶されており、機関の運転状態が機関の運転領域(NM)内でないときに、尿素水タンク(72)内の尿素水量が予め定められた量以下であると判別されたときには、走行計画生成部(14)は、走行計画生成部(14)により生成された複数の車両走行進路の中から機関の運転状態が機関の運転領域(NM)内に侵入しない車両走行進路を目標走行進路として決定する。【選択図】図18
