Suspension control device and control method therefor, and vehicle including the same

A control method, performed in a suspension system to control a damping force provided through each suspension in a vehicle, the control method comprising:

• identifying a current state of the vehicle using sensor data of a sensor unit of the vehicle;
• performing a first process of obtaining a current damping force for a damper of the suspension according to the identified current state;
• identifying an output range for an output of an actuator of a damper, which changes according to a damper speed;
• and
• performing a second process of determining a target damping force for the damper in consideration of the identified output range,
• wherein the performing of the second process comprises:
• determining the target damping force for a particular damper by correcting the current damping force for the particular damper, in response to determinations that the current damping force for the particular damper is out of the output range for the particular damper, and that there is a margin in an output of an actuator of a counterpart damper for the particular damper.

A vehicle including a suspension system, wherein the suspension system includes:

• a sensor unit configured to sense sensor data for identifying a current state of the vehicle;
• and
• a controller configured to control a damping force provided through each suspension according to the current state of the vehicle, which is identified using the sensor data of the sensor unit,
• the controller is configured to:
• perform a first process of obtaining a current damping force for a damper of each suspension according to the current state;
• identify an output range for an output of an actuator of each damper, which changes according to a damper speed;
• and
• perform a second process of determining a target damping force for each damper in consideration of the identified output range, and
• wherein, in the second process, the controller determines the target damping force for a particular damper by correcting the current damping force for the particular damper, in response to determination that:
• the current damping force for the particular damper is out of the output range for the particular damper;
• and that there is a margin in an output of an actuator of a counterpart damper for the particular damper.
