Title:
VERTICAL LOAD CONTROL DEVICE
Document Type and Number:
Japanese Patent JPH1148737
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To secure appropriate control and stabilized moving condition in the route traveling control for automobile by controlling a vertical load so as to be returned to a normative value in the case where a movement of a vehicle is deviated from the normative value by the influence of external disturbance. SOLUTION: Normative yaw rate and a normative lateral G are computed (ST7) in consideration of a coefficient friction on a road μ, and displacement of route is discriminated on the basis of a difference between the normative yaw rate and a real yaw rate and a difference between the normative lateral G and a real lateral G. In the case where this difference is large, since it takes time to correct in the ordinary automatic steering condition, correction is positively performed (ST9). Namely, a servo valve is driven so that a target load and a real load coincide with each other, and an actuator generates the stroke so as to generate the vertical acceleration for increasing the tire grounding load in any one of a mass on a spring and a mass under the spring.
