Zusammenfassung: | PROBLEM TO BE SOLVED: To accurately operate a pitch angle by vehicle height of either the front or the rear of a vehicle. SOLUTION: A vehicle height detecting means is installed either in a part Pf in the front direction of a vehicle, or a part Pr in the rear direction of a vehicle which are separated from each other by a specified distance (w), and a vehicle height hr is detected. A specified virtual value hfk is set in the vehicle height on the part out of the positions Pf and Pr in which part the detecting means is not installed. A pitch angle θ of the vehicle is operated on the basis of the vehicle height detection value hr, the vehicle height virtual value hfk and the distance (w). The vehicle height virtual value hfk is previously corrected as (hfk+α), on the basis of the number of crews, their positions, the weight of a cargo and its loading position, and the pitch angle θ is operated. Thereby an accurate pitch angle can be operated only by installing a vehicle height detecting means on one side out of the front and the rear of a vehicle, when the number of crews, their positions, the weight of cargo and its loading position are changed, so that the cost of equipment can be reduced. |
