VEHICLE CENTROID POSITION ESTIMATION DEVICE AND CENTROID POSITION ESTIMATION METHOD
Document Type and Number:
Japanese Patent JP2017128232
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a vehicle centroid position estimation device capable of estimating a centroid position on a spring with an increased accuracy.SOLUTION: A vehicle centroid position estimation device 10 comprises: a rear shaft suspension load calculation unit 41 for calculating loads F, Fon an air suspension; a rear shaft roll moment calculation unit 42 for calculating a roll moment Mof a rear shaft; a rear shaft roll angle calculation unit 43 for calculating a roll angle φof the rear shaft; an integrated roll rigidity calculation unit 44 for correcting integrated roll rigidity Kbased on a preset provisional value of integrated roll rigidity which is a unique value of the vehicle, the roll moment Mof the rear shaft and the roll angle φ, in a state including before and after adjustment of vehicle height; and a lateral centroid position calculation unit 45 for calculating a lateral centroid position ybased on a load Fon the spring, the roll moment Mof the rear shaft, the roll angle φ, and the integrated roll rigidity K.SELECTED DRAWING: Figure 3
