The invention relates to CAN bus control equipment, which is coupled to a CAN bus and external equipment and comprises a controller, at least five switching devices, a matching circuit and a CAN bus interface circuit, wherein the CAN bus interface circuit is applicable to reading communication signals inputted by the external equipment on the CAN bus; the controller is coupled to the CAN bus interface circuit and the at least five switching devices, and is applicable to controlling on or off of the at least five switching devices when the communication signals are detected to be abnormal so as to control the CAN bus to be disconnected with the external equipment and establish connection with the external equipment; and the matching circuit is applicable to being matched with the CAN bus. Potential safety hazards brought about by the external equipment for vehicle communication can be effectively avoided by adopting the bus control equipment.
