More Information
Summary:PURPOSE:To omit the unnecessary evading actions of a work vehicle and to improve the working efficiency by confirming the movement or non-movement of an obstacle for a fixed time when it is detected that the front obstacle has a temperature higher than a prescribed level and then evading the vehicle only when the non-movement of the obstacle is confirmed. CONSTITUTION:The drive of a work vehicle is stopped by a control means 2 for a prescribed time when a distance sensor 4 decides a distance less than a prescribed level to a front obstacle and a temperature sensor 5 detects a temperature higher than a prescribed level. Then the vehicle is evaded from the obstacle if this obstacle does not move. Thus it is possible to omit the unnecessary evading actions to such movable obstacles as the human beings, dogs, cats, etc. Then the working efficiency of the work vehicle is improved.
