System capable of automatically regulating line

The invention discloses a system capable of automatically regulating a line. The system comprises a navigation system, a fuel monitoring system, a speed monitoring system and a whole automobile control system, wherein the navigation system is used for selecting a proper travelling route according to the set destination; the fuel monitoring system is used for monitoring the current fuel capacity and sending the fuel capacity information to the whole automobile control system; the speed monitoring system is used for collecting the current automobile speed and sending the current automobile speed to the whole automobile control system; the whole automobile control system is used for calculating the theoretical fuel consumption capacity according to the received information; the theoretical fuel consumption capacity is compared with the current fuel capacity; when the fuel capacity is insufficient, the navigation system is used for collecting the information of gas stations on the way; a command is sent to the navigation system according to the principle of proximity to plan and change the travelling route by taking the nearby gas station as an intermediate station. According to the system, the user can be reminded in time to change the travelling route when the fuel oil is insufficient, and therefore inconvenience caused by the fact that the situation of insufficient fuel oil can not be known in time can be prevented.
