Embodiment Construction

[0019] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments. The same structures are given the same reference numerals in the drawings.

[0020] As an embodiment of the present invention, such as figure 1 The vehicle gateway system shown at least includes a gateway 103, a first bus and a second bus connected to the gateway 103, a first controller 101 connected to the first bus, and a second controller connected to the second bus. device 102. Of course, the gateway 103 may also be connected with a third bus, a fourth bus ( figure 1 Not shown in ) and other multiple buses, in this embodiment, only the first bus and the second bus are used for illustration. Likewise, there may be multiple controllers connected to each bus, and only the first controller 101 and the second controller 102 are used for schematic illustration in this embodiment.

[0021] The first signal sent by the first controller 101 is t...

Abstract

The invention discloses an automobile-used gateway system which comprises a first bus, a second bus, and a gateway connected with the first bus and the second bus, at least one first controller connected with the first bus, as well as at least one second controller connected with the second bus; the gateway is arranged to receive a first signal from the first bus and judge whether the first signal comes from the pre-arranged first controller or not, if yes, validity and real-time performance of the first signal are verified continuously, and otherwise, error reminding signals are sent onto the first bus and the second bus; if verification result is that the signal is right, the first signal is sent to the second controller through the second bus, otherwise, error reminding signals are sent onto the first bus and the second bus.

Description

technical field [0001] The invention relates to the technical field of automobiles, in particular to a vehicle gateway system. Background technique [0002] With the rapid development of modern automotive electronics, the number of controllers in the vehicle is increasing day by day. The traditional hard-wire communication method can no longer meet such a huge communication demand. Therefore, most controllers have adopted bus communication for signal transmission. The signals that can be transmitted on a bus are not unlimited. When the bus load rate reaches a certain level, the number of buses can only be increased. Therefore, a gateway is needed as a medium for signal transmission between buses. [0003] The main function of the traditional gateway is the transmission and routing of signals, and the controller of the vehicle analyzes the signals after receiving them. With the increase of the number of controllers on the vehicle, the signal definitions of different models a...
