The invention discloses a method and a device for vehicle network access control. The method mainly comprises steps that an access request sent by the external equipment is received; whether connection according to a handshake protocol with the external equipment is required is determined, and the handshake protocol comprises identity identification of the external equipment and vehicle network activation; if required, the identity of the external equipment is identified according to the handshake protocol; when the identity of the external equipment is identified to be legal, a vehicle network requested by the external equipment for access is activated according to the handshake protocol, and the activated vehicle network accepts access operation of the external equipment. Through the method and the device, the vehicle network can be protected from being accessed by illegal equipment, and possibility of cracking original factory protocols carried out by illegal equipment can be reduced.
