Abstract:
1. A vehicle control device, 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, wherein, when the stroke speed is equal to or less than the predetermined value, the damping force variable region excludes high damping force side damping characteristics, and an engine is configured to output the driving force based on the driving force control, and the damping force variable shock absorber is configured to output the damping force corresponding to the damping force control amount to thereby suppress the change in the sprung mass behavior, and wherein the damping force generated according to the high damping force side damping characteristics at an arbitrary stroke speed is configured to be greater than the damping force generated according to a low damping force side damping characteristics.
