The invention discloses a high beam and low beam automatic switching device, a switch, a control method and a vehicle, and relates to the technical field of automobile parts, the high beam and low beam automatic switching device comprises a measuring module, a vehicle body controller, a central processing module or an MCU, the switch, a relay and a storage battery, and the central processing module or the MCU is connected with the measuring module and the vehicle body controller at the same time. The measuring module comprises a measuring instrument, namely a laser range finder and/or an infrared range finder and/or an ultrasonic range finder. According to the invention, automatic switching of the high beam and the low beam of the vehicle is realized. A control method based on the high beam and low beam automatic switching device comprises the following steps that S1, a threshold value S0 is set in an MCU; s2, the relative speed S1 of the front vehicle is measured through a range finder, and the relative distance S2 and S3 of the front vehicle are measured at intervals at the same time, and S3, a result is obtained through comparison of S2 and S3 and comparison of S1 and S0, so that a low beam or a high beam is turned on through a vehicle body controller. The method can realize automatic switching of the high beam and the low beam, and can be applied to the automatic driving technology of an automobile.
