An integrated chassis control system includes a first sensor configured to sense a first vehicle driving in a lane adjacent to a lane in which an own vehicle is driving and to sense behavior information of the first vehicle, a second sensor configured to sense a variation in behavior of the own vehicle, a first determinator configured to determine a degree of influence of a side wind, which is predicted to occur due to the first vehicle, based on the behavior information of the first vehicle, a second determinator configured to determine a variance in abnormal behavior of the own vehicle based on information sensed by the second sensor, a first controller configured to perform a semi-active chassis system control, and a second controller configured to perform an active chassis system control.

Integrated chassis control system

An apparatus and a method for determining a mounting state of an electronic control unit (ECU) of an electronic controlled suspension (ECS) system can determine either a normal mounting state or a mounting failure of the ECU of the ECS system. The apparatus for determining the mounting state of the ECU includes: a signal processor receiving a damper velocity of each damper; an integrator calculating an integral of the damper velocity by integrating the damper velocity of each damper received by the signal processor per unit time; a comparator comparing the integral of the damper velocity calculated by the integrator with an actual stroke of each damper; and an index output unit outputting a mounting state of the ECU in the form of an index according to comparison results of the comparator.

Apparatus and method for determining mounting state of electronic control unit of electronically controlled suspension system

A suspension control system and a method thereof are provided. Steering characteristics (e.g., under-steering and over-steering) of a running vehicle are analyzed to calculate lateral force of wheels and normal load (or normal force) of the wheels is calculated based on the lateral force. In addition, a current that corresponds to a total current value obtained by adding a yaw control current value corresponding to the normal force and a roll control current value is applied to a damper of the corresponding vehicles to perform roll control and yaw control of the vehicle.
