PROBLEM TO BE SOLVED: To provide a vehicular suspension control device capable of keeping adequate ground contact properties of a wheel, and maintaining braking performance and vehicular stability in a high-dimensional manner by adequately and variably setting a damping force characteristic by determining not only the unevenness situation of a road surface but also the fine determination of a road surface situation. SOLUTION: A suspension_ECU 20 basically sets the characteristic to low-damping side for off-road travel and to a high-damping side for regular road travel, and controls characteristics of damping forces of shock absorbers 4fl, 4fr, 4rl and 4rr. When detecting traveling on a slippery road surface based on the signal of an outside air temperature AT, the selection/non-selection of a snow mode, a road surface friction coefficientμ, the operation/non-operation of an ABS 16, the operation/non-operation of a TCS 17, and the operation/non-operation of a VDC system 18, control is performed by setting the characteristic on the low damping side.
