Embodiment Construction
[0013] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.
[0014] A schematic diagram of the vehicle circuit connection of a two-wire automotive electronic control system of the present invention, as shown in figure 1 As shown, it includes a battery 1 , a generator 6 , a starter motor 5 , and automotive electronic components 7 . The generator 6 is represented as A in the figure, and the starter motor 5 is represented as M in the figure. Since the generator 6 and the starter motor 5 require a large current during operation, which is about 100-300A, they are directly connected to the battery 1 , powered by battery 1. The remaining automotive electronic components 7 are connected with two-wire interface circuit modules 4, and are powered by the battery 1 through their respective two-wire interface circuit modules 4, and the two-wire interface circuit modules 4 are connected in parallel at the positive and negativ...

The invention discloses a two-wire automotive electronic control system. The two-wire automotive electronic control system comprises a storage battery, a generator, a starting motor, automotive electronic components and a total electric wire, wherein the storage battery serves as a power supply, and the generator and the starting motor are parallelly connected with the positive terminal and the negative terminal of the storage battery. The two-wire automotive electronic control system further comprises two-wire interface circuit modules; the generator, the starting motor and the automotive electronic components are respectively connected with one two-wire interface circuit module; the two-wire interface circuit modules are parallelly connected with the positive terminal and the negative terminal of the storage battery; and the total electric wire can supply power to the automotive electronic components by serving as a power line and can also be used for transmitting / receiving signals among the automotive electronic components by serving as a signal line. According to the two-wire automotive electronic control system, except for the generator and the starting motor, the power supply and communication control of rest automotive electronic components can be carried out in a manner that the rest automotive electronic components are connected with one another by using two electric wires; and the two-wire automotive electronic control system has the advantages of long-distance transmission, stronger anti-jamming performance, and better safety and stability.
Description
technical field [0001] The present invention relates to an automobile electronic control system, in particular to an automobile electronic control system in which there are only two electric wires in the entire vehicle except for a generator and a starter motor in a physical sense to connect the electronic components of the entire vehicle. Background technique [0002] At present, the circuit connection between the current automotive electronic components generally adopts the automotive electronic component control system composed of two power lines and several signal lines. In this traditional automotive electronic component control system, the communication of each associated automotive electronic component adopts a point-to-point communication method. Therefore, under this premise, if there are n pairs of communication points in an electronic component of a car, n pairs of communication points must be used. car wires. With the increase of automobile functions and the wid...
