Suspension control system

A suspension control system comprising:

• a suspension, which suspends a wheel on a vehicle body;
• an actuator, which changes a damping force of a damper of the suspension;
• an acceleration sensor, which detects at least one of a lateral acceleration and a longitudinal acceleration of a vehicle;
• acceleration derivative value calculating means, which differentiates the acceleration detected by the acceleration sensor to calculate an acceleration derivative value;
• target load calculating means, which calculates, based on the acceleration derivative value, a target load to be generated by the actuator;
• target electrical current calculating means, which calculates, based on the target load, a target electrical current to be supplied to the actuator;
• and
• a load sensor disposed between the damper and the vehicle body to detect an actual load input from the damper to the vehicle body,
• wherein the target electrical current calculating means sets the target electrical current to be supplied to the actuator so that the actual load detected by the load sensor is identical to the target load.

A suspension control system comprising:

• a suspension, which suspends a wheel on a vehicle body;
• an actuator, which changes a damping force of a damper of the suspension;
• a posture control portion, which calculates a parameter for controlling a posture of a vehicle including at least one of a roll and a pitch;
• a riding comfort control portion, which calculates a parameter for suppressing a vibration transmitted from a road surface to control riding comfort of the vehicle;
• and
• a high select portion, which outputs a larger one of the parameter calculated by the posture control portion and the parameter calculated by the riding comfort control portion to control the damping force of the damper.

• and
• an addition portion, which adds together the parameter calculated by the posture control portion and the parameter calculated by the riding comfort control portion to control the damping force of the damper.
