An integrated control system includes a main control system (accelerator) controlling a driving system, a main control system (brake) controlling a brake system, a main control system (steering) controlling a steering system, an adviser unit generating and providing information to be used at each control system based on environmental information around the vehicle or information related to a driver, and an agent unit. The agent unit executes a program including a process of determining a control precondition, a step of calculating an instructed distance or a target distance to an instructed position, and a process of guarding (regulating) by environmental information.
