An integrated vehicle motion control system is provided in which the software configuration is formed in a hierarchical structure, and includes (a) a command section adapted to determine target vehicle state quantities based on driving related information, and (b) an executing section adapted to receive the target vehicle state quantities as commands from the command section, and execute the commands by means of a plurality of actuators. The command section includes an upper-level command section adapted to determine first target vehicle state quantities based on the driving related information, without taking account of the dynamic behavior of the vehicle, and a lower-level command section adapted to determine second target vehicle state quantities inview of the dynamic behavior of the vehicle.
