    Abstract: A damper control device (1) feeds back a pressure within an extension-side chamber (R1) to control an extension-side solenoid valve (S1) that adjusts the pressure within the extension-side chamber (R1), and feeds back a pressure within a compression-side chamber (R2) to control a compression-side solenoid valve (S2) that adjusts the pressure within the compression-side chamber (R2). The damper control device (1) performs a compression-side reduction correction which reduces a compression-side current (Ic) supplied to the compression-side solenoid valve (S2) during extension of a damper (100), and performs an extension-side reduction correction which reduces an extension-side current (Ie) supplied to the extension-side solenoid valve (S1) during contraction of the damper (100).

    Abstract: A damper control device 1 includes a rate sensor 2 that detects a pitching angular velocity É of a vehicle body B of a two-wheeled vehicle, a vehicle speed sensor 7, a steering angle sensor 8 and a calculation unit 9 that detect a roll angle ¸ and a yaw angular velocity Õ of the vehicle body B, a pressure sensor 3 that detects a pressure Pf of a contraction-side chamber R2 in a front-wheel side damper FD, a pressure sensor 4 that detects a pressure Pr of a contraction-side chamber R2 in a rear-wheel side damper RD, and a correction unit 6 that corrects the pitching angular velocity É on the basis of the roll angle ¸ and the yaw angular velocity (p. The pressures Pf and Pr are controlled on the basis of the corrected pitching angular velocity É and the pressures Pf and Pr. The vehicle speed sensor 7, the steering angle sensor 8 and the calculation unit 9 detect the roll angle ¸ and the yaw angular velocity Õ on the basis of a traveling speed Vm and a steering angle ¸h.

    Abstract: The damper control device 1 includes a three axis rate sensor 2 that detects a pitching angular velocity É of a vehicle body B of a two-wheeled vehicle, a pressure sensor 3 that detects a pressure Pf of a contraction-side chamber R2 in a front-wheel side damper FD interposed between the vehicle body B and a front-wheel FW, a pressure sensor 4 that detects a pressure Pr of a contraction-side chamber R2 of a rear-wheel side damper RD interposed between the vehicle body B and the rear-wheel RW, and a correction unit 6 that corrects the pitching angular velocity É. The damper control device 1 controls the pressure Pf of the contraction-side chamber R2 in the front-wheel side damper FD and the pressure Pr of the contraction-side chamber R2 of the rear-wheel side damper RD on the basis of the corrected pitching angular velocity É, the pressure Pf of the contraction-side chamber R2 in the front-wheel side damper FD and the pressure Pr of the contraction-side chamber R2 of the rear-wheel side damper RD.

    Abstract: A shock absorber includes a piston joined to a piston rod that proceeds into and recedes from a cylinder, an extension-side chamber and a compression-side chamber that are separated from each other by the piston and have a working fluid reserved therein, first and second extension-side discharge passages in which the working fluid discharged from the extension-side chamber flows, an extension-side supply passage in which the working fluid to be supplied to the compression-side chamber flows, first and second compression-side discharge passages in which the working fluid discharged from the compression-side chamber flows, and a compression-side supply passage in which the working fluid to be supplied to the extension-side chamber flows. An extension-side damping valve and a compression-side damping valve are respectively provided in the first extension-side discharge passage and the first compression-side discharge passage. An extension-side electromagnetic pressure control valve and a compression-side electromagnetic pressure control valve, which are respectively provided in the second extension-side discharge passage and the second compression-side discharge passage, are set such that the openings thereof are maximized before the piston speed reaches a high-speed range.
