Title:
AXLE WEIGHT TRANSFER CONTROL DEVICE FOR REAR TWO-AXLE VEHICLE
Document Type and Number:
Japanese Patent JPH11291734
Kind Code:
A
Abstract:

To provide an axle weight transfer control device for a rear two-axle vehicle capable of properly maintaining axle weight distribution ratio without an influence by fluctuation of a detection value due to a change of vehicle behavior, even by performing axle weight transfer control by an air spring continuously from stopping time over to starting time.

In controlling of operation of a supply/discharge valve unit for supplying/discharging an air pressure to/from an air spring, a target pressure in the air spring is set from a load data at stopping time, operation of the supply/discharge valve unit is feedback controlled, and prescribed axle weight distribution ratio is attained. When a pulse edge is detected from a pulse signal of a vehicle speed sensor, operation control of the supply/discharge valve unit performed till this time is immediately suspended (step S24). In this way, an influence by the load data due to a change of vehicle behavior and by fluctuation of actual air pressure at starting time is eliminated, so as to properly hold axle weight distribution ratio.
