摘要： A beam tracking method and apparatus, describes that, during vehicle platooning, following vehicles have a low reliability of receiving a beam signal and a low speed of discovering a beam signal. Said method includes: receiving first position information of a designated vehicle obtaining, on the basis of the first position information and second position information of a following vehicle, relative position information of the designated vehicle and the following vehicle; and tracking, according to the relative position information, a beam transmitted by the designated vehicle.
