VEHICLE CONTROL DEVICE AND METHOD

摘要

A power source attitude control is performed to suppress changes in the sprung mass behavior of a vehicle, and damping force control for damping force variable shock absorbers is performed to suppress changes in the sprung mass behavior. When the stroke speed is low, the saturation degree of the damping force variable shock absorbers is set smaller than the saturation degree when the stroke speed is high.

主权项

1. A vehicle control system, comprising:
a sprung mass behavior detecting means that detects change in sprung mass behavior of a vehicle; a power source that outputs a driving force based on a driving force control to suppress the change in the sprung mass behavior; a damping force variable shock absorber that outputs a damping force based on a damping force control to suppress the change in the sprung mass behavior; a stroke speed detecting means that detects a stroke speed of the damping force variable shock absorber; and a damping force control amount calculation means that calculates a damping force control amount based on the damping force control within a range of a damping force variable region with a predetermined width prescribed by a saturation degree, in which the saturation degree of the damping force variable region of the damping force variable shock absorber is set lower when the stroke speed is equal to a predetermined value or less than when the stroke speed is greater than the predetermined value.
