The invention relates to the technical field of vehicle high beam and low beam control, in particular to an automatic switching method and system for a high beam and a low beam during night driving of a vehicle. According to the automatic switching method and system for the high beam and the low beam during night driving of the vehicle, the high beam and the low beam of the vehicle can be automatically switched according to different driving road conditions at night, the burden of attention of a driver is effectively relieved, and the safety of night driving of the vehicle is improved; the road types are divided into three types according to whether the isolation belt exists or not and whether the turning exists or not, and the corresponding boundary conditions for switching the high beam and the low beam are set according to the road types, so that the intelligence and pertinence of the automatic switching strategy of the high beam and the low beam can be improved, and the driving experience is enhanced; according to the method, interpolation processing is carried out on vehicle state information parameters, the collection time of all information can be synchronized, the accuracy of system control is improved, and meanwhile the processing operation efficiency of the system can be further improved by establishing a vehicle space rectangular coordinate system and converting a vehicle position information coordinate system.
