An apparatus for controlling a suspension of a vehicle to improve high-speed driving stability of the vehicle includes: a sensor that obtains information about a road surface ahead the vehicle during travel of the vehicle; and a controller that derives a height value of the road surface from the information about the road surface, determines a state of the road surface based on a differential value of the derived height value, predicts vehicle behavior corresponding to the determined state of the road surface, and controls a damping force of the suspension based on the predicted vehicle behavior.

Apparatus and method for controlling suspension of vehicle

An apparatus for controlling a suspension of a vehicle to improve ride comfort of the vehicle includes: a sensor that measures rainfall around the vehicle, a camera that takes an image of a road surface ahead the vehicle, and a controller that recognizes an obstacle located on the road surface based on the image of the road surface ahead the vehicle. In particular, the controller determines a type of the obstacle depending on the measured rainfall around the vehicle, and controls a damping force of the suspension based on control information corresponding to the determined type of the obstacle when the vehicle passes over the obstacle.

An apparatus for controlling a suspension of a vehicle includes: an illuminance sensor that measures illuminance outside the vehicle, a camera that takes an image of a road surface ahead the vehicle, and a controller that recognizes an obstacle located on the road surface based on the image of the road surface ahead the vehicle, determines a type of the obstacle depending on the measured illuminance outside the vehicle, and controls a damping force of the suspension based on control information corresponding to the type of the obstacle when the vehicle passes over the obstacle.

A vehicle suspension control apparatus includes a mode determination device that determines a suspension control mode corresponding to an identified front road surface, in response to the front road surface of a vehicle being identified, a suspension control amount calculation device that calculates an amount of suspension control for passing through the identified front road surface, based on the determined suspension control mode, and a controller that controls a suspension of the vehicle based on the calculated amount of suspension control.

Vehicle suspension control apparatus and method thereof

A vehicle suspension control apparatus includes a mode determination device that determines a mode of a shock absorber for a vehicle, corresponding to an identified speed bump, when the speed bump is identified in front of the vehicle, a suspension control amount calculation device that calculates an amount of suspension control for passing over the speed bump, based on the determined mode of the shock absorber, and a controller that controls a suspension of the vehicle based on the calculated amount of suspension control.

A failure detection apparatus and method of the MDPS may include a configuration that determines a failure of the MDPS in accordance with a vehicle speed, a steering torque, steering angle, a motor torque, and an estimated yaw rate, and when it is determined that the MDPS breaks down, additionally determines the type of failure.

Failure detection apparatus of motor drive power system and method of the same

Disclosed are a control system and a control method for fail safety of a motor driven power steering (MDPS). The system may include a straight motion/turning determination module for determining whether a vehicle is in a straight motion or turning based on a steering angle of a steering wheel, a steering torque of the steering wheel and a vehicle speed of the vehicle, a fail determination module for determining whether an MDPS fail occurs based on a steering torque of a driver and a motor torque of the MDPS if the vehicle is in the straight motion, a fail type determination module for determining a type of the MDPS fail using a yaw rate change rate if the MDPS fail occurs, and a yaw rate change rate detection module for inputting the yaw rate change rate to the fail type determination module.
