The invention provides a pre-aiming and early warning system for an automobile turning path and a method of the system. The system comprises an embedded system, a steering wheel angle sensor, a locating module, a touch display screen, a power source and a storage unit, wherein the power source and the storage unit are connected with the embedded system. The embedded system serves as a host and stores an off-line map. A turning track is displayed on the touch display screen according to data of an existing steering wheel angle, the position and the speed of a user currently. Safety is judged according to the automobile position, the steering wheel angle and the speed. An early warning is given if it is judged that the existing travelling path is dangerous. The steering wheel angle sensor provides angle signals for the embedded system. The locating module provides position parameters and speed parameters. The touch display screen displays the map and early warning information. By the adoption of the system and the method, the probability of traffic accidents happening in the turning process of an automobile is reduced, estimation errors of a driver are avoided, the automobile turning path can be acquired in a pre-aiming manner and compared with a preset turning path, and warnings can be given to the driver in real time.
