Abstract

PURPOSE: To easily perform a horizontal control of attitude for a car body and surely prevent the car body from being turned over, by detecting both tilt angles of the car body in two directions and landing states of its outriggers.
CONSTITUTION: In four outriggers whose vertexes are shown by points AWD respectively, when assumed the point A for an origin of coordinates, the leveling work of a plane surrounded by the points AWD can be performed by rotating the plane ABCD about the axis AB by an angle α then about the axis AD' by an angle θ. To be concrete, the tilt angles θ, α are detected by tiltmeters 10, 11. Those of said tiltmeters output a signal in accordance with positive and negative polarities of the angle to obtain a control direction for each outrigger by a logical operation circuit including inverters 12, 13. Then an up-command for the vertexes AWD is output from NAND circuits 14W17, while a down-command is output from inverter 18W21.
