Abstract

The invention provides an automobile gateway system and a control method thereof. The automobile gateway system comprises a plurality of control modules (10), a CAN network (20), a CAN bus (30) and a gateway controller (40), wherein each control module (10) is connected with the CAN bus (30) through the CAN network (20); the gateway controller (40) is connected with the CAN bus (30) and used for coordinating message transmission among the control modules (10) and sends permissive messages to each control module (10) at fixed time, wherein the permissive messages indicate that the control modules (10) are permitted to send respective CAN messages to the CAN network (20); and the control modules (10) determine whether to send the respective CAN messages to the CAN network (20) or not according to whether receiving the permissive messages within a predetermined time period or not. The automobile gateway system and the control method thereof can effectively prevent the signal blockage and enhance the safety of automobiles.

Description

technical field [0001] The invention relates to an automobile gateway system and a control method thereof. Background technique [0002] With the development of the automobile industry, more and more electronic devices are applied to the automobile, such as GPS, DVD, radio, air conditioning system and so on. Moreover, compared with traditional fuel vehicles, there are a large number of electronic devices in the control systems of the latest gasoline-electric hybrid vehicles and pure electric vehicles. While the increase of various electronic devices brings comfort and convenience to users, it also causes various problems, the most typical of which is the problem of signal transmission between various electronic devices. [0003] Such as figure 1 As shown, in the existing automotive gateway system, the control modules 10' of each electronic device are connected to each other through the CAN network 20, the CAN bus 30, and the gateway controller 40', thereby realizing the co...
