This system includes a car series consisting of at least two cars. The inter-car comm. sub-system (ICS) of the leading car sends the running and situation info to the car behind. ICS of the latter sends info to the driving decision-making system (DD) of this car. When DD receives info, the situation supervision sub-system (SS) of this car offers the Driving Situation of this Car (DSC) to DD, too. DD combines and analyzes these two info then sends instruction to the situation self-control sub-system (SC). SC combines the instruction and the info from SS, then finally real time controls DSC via the car control port sub-system. This invention reduces the driver's tired degree, the accident occurring rate and driving cost.
