Abstract
A pitch angle calculating device includes a height sensor 11 arranged in either one of a front position,and the rear position,separated from the front position,by a predetermined distance w, detecting either one of a front vehicle height,and a rear vehicle height,and a controller 7 calculating a pitch angle of the vehicle on the basis of the detected vehicle height,, the predetermined distance,and a designated virtual height,established as the other vehicle height,which is not detected by the height sensor 11. The designated virtual height,is corrected into a corrected height (hfk+&agr;) by both number and positions of passengers on the vehicle and both weight and position of loads on the vehicle in advance of calculating the pitch angle by the controller 7. If only providing the height sensor 11 in either one of the front position,and the rear position,against changes in number and position of passengers or weight and position of loads on the vehicle, it is possible to calculate the accurate pitch angle, so that the manufacturing cost of the device can be reduced.
