Title:
METHOD AND DEVICE FOR CONTROLLING VERTICAL MOTION OF AUTOMOBILE
Document Type and Number:
Japanese Patent JP2000158978
Kind Code:
A
Abstract:

To provide a method and device for controlling vertical motion of an automobile allowing consideration to nonlinear vehicle vertical motion behavior with satisfactory precision at a comparatively low calculation cost.

A drive system operation signal U is obtained from actual traveling state data vist, aist, m, αs, ig, a target acceleration asoll according to supplied input data, and a target vertical speed vsi and a target vertical acceleration asi obtained in a controller on the basis of the actual traveling state. That is, a target drive system operation signal Uas is obtained on the basis of a reverse vehicle vertical motion characteristic curve graph according to the target vertical speed vsi and the target vertical acceleration asi in the controller, and the actual traveling state data m, αs, ig, while the drive system operation signal Ua is obtained from the target drive system operation signal Uas.
