The work of a driver is reduced while suppressing a reduction in work efficiency and excessive fuel consumption. A direction control part (60M) performs automatic straight-ahead control for allowing a vehicle body to travel on a target straight-ahead route based on the positioning result and the like of a positioning unit (86) in a control target region of the target straight-ahead route. An operation control part (60G) performs non-operation state switching control for switching a groundwork device into a non-operation state when a transition detection part (70) detects that the vehicle body has transitioned from a straight-ahead state to a direction change state, and performs operation state switching control for switching the groundwork device (A) into an operation state when the transition detection part (70) detects that the vehicle body has transitioned from a direction change state to a straight-ahead state. An engine control part (60H) performs temporary engine stop control when temporary stop conditions are satisfied and performs engine restart control when restart conditions are satisfied. A direction control part (60M) stops the automatic straight-ahead control when the temporary engine stop control is performed during the automatic straight-ahead control and restarts the automatic straight-ahead control when the engine restart control is performed during the stop of the automatic straight-ahead control.

    작업 효율의 저하, 낭비적인 연료 소비를 억제하면서, 운전자의 노동력을 경감한다. 방향 제어부(60M)는, 목표 직진 경로의 제어 대상 영역에서는, 측위 유닛(86)의 측위 결과 등에 기초하여 차체를 목표 직진 경로 상에서 주행시키는 자동 직진 제어를 행하고, 작업 제어부(60G)는, 추이 검출부(70)에 의한 차체의 직진 상태에서 방향 전환 상태로의 이행 검출로 대지 작업 장치를 비작업 상태로 전환하는 비작업 상태 전환 제어를 행하고, 추이 검출부(70)에 의한 차체의 방향 전환 상태에서 직진 상태로의 이행 검출로 대지 작업 장치(A)를 작업 상태로 전환하는 작업 상태 전환 제어를 행하고, 엔진 제어부(60H)는, 일시 정지 조건의 성립으로 엔진 일시 정지 제어를 행하고, 재시동 조건의 성립으로 엔진 재시동 제어를 행하고, 방향 제어부(60M)는, 자동 직진 제어 중에서의 엔진 일시 정지 제어의 실행으로 자동 직진 제어를 중단하고, 또한 자동 직진 제어의 중단 중에서의 엔진 재시동 제어의 실행으로 자동 직진 제어를 재개한다.
