The invention discloses a data transmission method for assisting a vehicle ad hoc network based on an intelligent reflecting surface, and the method comprises the steps: enabling a vehicle node to reserve an available time slot in a control channel in a time division multiplexing mode, and enabling the vehicle node to cache V2V data; after the time slot successfully reserved by the vehicle node arrives, if data to be sent exists, checking whether a sending object is in a one-hop range, selecting whether to directly send the V2V data or to send the V2V data by adopting multi-hop forwarding according to a checking result, and when the V2V data is directly sent or the V2V data is sent between adjacent forwarding nodes in the multi-hop forwarding, sending the V2V data to the adjacent forwarding nodes in the multi-hop forwarding; and judging whether a straight line between the two nodes passes through the coordinates of the building or not through the coordinates, and selecting whether to start RIS-assisted V2V da
