Abstract:
1. A suspension control system comprising: a suspension device that connects a sprung member of a vehicle with an unsprung member of the vehicle; an actuator that adjusts frictional force along a stroke direction of the suspension device; and an electronic control unit configured to control the actuator, based on a velocity direction of the sprung member parallel to a stroke direction of the suspension device, and a stroke velocity direction of the suspension device, so as to adjust a suspension frictional force that is the frictional force along the stroke direction of the suspension device, the electronic control unit being configured to adjust a magnitude of the suspension frictional force, so that the suspension frictional force becomes substantially equal to a required frictional force determined based on a value obtained by exponentiating the velocity of the sprung member, and another value obtained by exponentiating a stroke velocity of the suspension device, wherein: an exponent of the value obtained by exponentiating the velocity of the sprung member is larger than an exponent of the another value obtained by exponentiating the stroke velocity of the suspension device; and the exponent of the value obtained by exponentiating the velocity of the sprung member and the exponent of the another value obtained by exponentiating the stroke velocity of the suspension device are natural numbers, each of the value and the another value being larger than or equal to 1.
