Vehicle control device

摘要

A vehicle control device includes a variable-damping-force shock absorber, a front wheel speed sensor, a rear wheel speed estimation device, a damping force control amount calculation device configured to calculate a damping force control amount for the variable-damping-force shock absorber according to frequency scalar quantities, when the front wheel speed detected by the front wheel speed sensors and the size of an amplitude of a frequency of the rear wheel speed estimated by the rear wheel speed estimation device are frequency scalar quantities, and a damping force control device configured to control the damping force of the variable-damping-force shock absorber on the basis of the damping force control amount calculated by the damping force control amount calculation device, the rear wheel speed estimation device prohibiting the estimation of the real wheel speed when a vehicle speed is equal to or greater than a high vehicle speed threshold value.
