Abstract
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.
Claims12
An integrated chassis control system comprising:
- 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, which controls a driving mode of the own vehicle, when the degree of influence of the side wind, which is predicted by the first determinator, is greater than or equal to a predetermined setting value;
- and
- a second controller configured to perform an active chassis system control by calculating a control value for stabilizing the behavior of the own vehicle according to the variance in abnormal behavior of the own vehicle which is determined by the second determinator,
- wherein the semi-active chassis system control includes control of a motor-driven power steering (MDPS) system and a semi-active suspension system (electronic controlled suspension (ECS) system) of the own vehicle,
- the active chassis system control includes control of a rear wheel steering (RWS) system and an electronic stability control (ESC) system of the own vehicle,
- when the second controller performs control of stabilizing the behavior of the own vehicle, the second controller first performs steering control of the own vehicle through the RWS system to generate lateral force, and
- when generation of additional lateral force is required so as to further stabilize the behavior of the own vehicle, the second controller additionally performs partial braking through the ESC system.
