PROBLEM TO BE SOLVED: To provide a control device for a damping-force variable damper that achieves improvement or the like in steering stability during turning running. SOLUTION: A front-wheel damping-force correction part 59 executes the following operation. After calculating a steering-angle speed Sδof a steering wheel 22 on the basis of a steering angleδinputted from a steering-angle sensor 26 in a step S21, a damping-force correction base value DCb is calculated on the basis of the steering-angle speed Sδin a step S22. After estimating a friction coefficientμof a traveling road-surface on the basis of a yaw rateγinputted from a yaw-rate sensor 12, a steering angleδinputted from a steering-angle sensor 26, and a vehicle speed v inputted from a vehicle-speed sensor 9 in a step S23, aμgain Gμis set on the basis of the friction coefficientμ. A vehicle-speed gain Gv is set on the basis of the vehicle speed v inputted from the vehicle-speed sensor 9 in a step S25. A damping-force correction value DC is calculated by multiplying a damping-force correction base value DCb by theμgain Gμand the vehicle-speed gain Gv in a step S26. COPYRIGHT: (C)2009,JPO&INPIT
