Abstract
Proposed are an apparatus for and a method of controlling a vehicle suspension. The apparatus includes a sensor configured to acquire at least one of information on a road surface in front of a vehicle and state information of the vehicle; and a processor configured to predict a vehicular behavior based on the information acquired through the sensor and actuator information and to control at least one of a ride height of the vehicle, stiffness of an air spring, and a damping force of a damper based on the predicted vehicular behavior.
Claims13
An apparatus for controlling a vehicle suspension system of a vehicle, the apparatus comprising:
- a sensor configured to acquire at least one of information on a road surface in front of a vehicle and state information of the vehicle;
- and
- a processor configured to predict a vehicular behavior based on the information acquired through the sensor and actuator information and to control at least one of a ride height of the vehicle and a stiffness of an air spring based on the predicted vehicular behavior;
- wherein the processor, as configured, performs, before the vehicle reaches an obstacle:
- setting the ride height of the vehicle into a high mode and the stiffness of the air spring into a soft mode when a prediction value of the predicted vehicular behavior is equal to or higher than a first reference value;
- setting the ride height of the vehicle into a normal mode and the stiffness of the air spring into a normal mode, when the prediction value of the predicted vehicular behavior is higher than a second reference value and lower than the first reference value;
- and
- setting the ride height of the vehicle into the normal mode and the stiffness of the air spring into a hard mode when the prediction value of the predicted vehicular behavior is equal to or lower than the second reference value, and
- wherein the first reference value is higher than the second reference value.
A method of controlling a vehicle suspension, the method comprising:
- receiving at least one of information on a road surface in front of a vehicle, state information of the vehicle, and actuator information;
- predicting vehicular behavior based on the received information;
- and
- controlling at least one of a ride height of the vehicle, a stiffness of an air spring, and a damping force of a damper based on the predicted vehicular behavior;
- wherein in the controlling of at least one of the ride height of the vehicle, the stiffness of the air spring, and the damping force of the damper, the method comprising comparing a prediction value of at least one of behavioral components included in the predicted vehicular behavior with one or more predetermined reference values and controlling at least one of the ride height of the vehicle and the stiffness of the air spring according to a result of the comparison.
