Integration Chassis Control (ICC) Systems of Mando 2004-01-2044

This paper presents the integrated chassis control (ICC) system under development at MANDO. By sharing the sensor and control information through the communication link among the existing 2 or more chassis subsystems, the integrated chassis control system improves vehicle performance and reduces cost for the sensors and related wiring. ICC consists of continuously variable damping control system(CDC), rear toe angle control system(AGCS) and electronic stability program (ESP). In ICC, the steering angle and yaw control information of ESP are delivered to the other systems through the CAN interface, and co-operative control strategy overrides each subsystem to improve the vehicle handling performance and stability. The effectiveness of both integrated chassis control systems are illustrated by a computer simulation and vehicle test on dry asphalt, snow road surface and so on.
