In the publication number CN101323303, the patent name is "A Central Coordination Method and Coordinator for Automobile Control", which uses a unique coordinator to control all electrical appliances in the automotive electrical system. Although this method realizes the The linkage relationship, restriction relationship, substitution relationship and indirect control relationship among them, but when the only coordinator fails, it will cause the complete vehicle electrical system to be paralyzed, so its reliability is low

Embodiment Construction
[0012] The present invention will be described in detail below in conjunction with the accompanying drawings and embodiments.
[0013] Such as figure 1 As shown, it is a structural block diagram of the congruent double central coordinator of the present invention, which includes two congruent coordinators 1 and 2 with the same structure and composition, and a vehicle-mounted communication interface 3 is respectively arranged outside the congruent coordinators 1 and 2, An automatic arbitration module 4 is arranged inside, and the congruent coordinators 1 and 2 are respectively connected to the vehicle electrical system network 5 through their respective vehicle communication interfaces 3, and mutual control is realized through the vehicle electrical system network 5.
[0014] The working principle of the congruent double central coordinator of the present invention is: after the system is powered on, the congruent coordinators 1 and 2 judge their working status through their re...

The invention discloses an interactive control method of double congruent central coordinators, which includes the following steps that: 1) two coordinators are arranged in an electrical system network of an automobile, wherein the two coordinators are congruent coordinators with identical structure, two vehicle-mounted communication ports are respectively arranged on the two coordinators, the two vehicle-mounted communication ports are connected to the electrical system network of the automobile, and each coordinator is provided with an automatic arbitration module inside; 2) after the electrical system network of the automobile is powered on, the automatic arbitration modules arranged inside the two coordinators start to work; 3)the automatic arbitration modules arbitrate the control rights of the two coordinators, that is to determine that the two coordinators are respectively at a main control coordinator mode or a standby coordinator mode; and 4) after the automatic arbitration modules finish the arbitration over the control rights of the two coordinators and show the working modes of the two coordinators, the two coordinators enter the periodic working flow. The invention isunique in structural design and the two coordinators have strong interactive control and monitoring abilities, so the method is widely applicable in electrical systems of automobiles.
Description
technical field [0001] The invention relates to a mutual control method, in particular to a mutual control method for congruent dual central coordinators of automobiles. Background technique [0002] In order to improve the comfort and safety of automobiles, more and more automotive electrical appliances are installed in modern automobiles, and their functions are becoming more and more complex. For example, electric heated and ventilated seats, electric rearview mirrors and electric windows used in automobiles improve the comfort of automobiles; in addition, electric defrosting and automatic follow-up headlights are used to increase the safety of automobiles when driving. [0003] The electrical system of a car as a whole requires coordinated control of the overall function. In the publication number CN101323303, the patent name is "A Central Coordination Method and Coordinator for Automobile Control", which uses a unique coordinator to control all electrical appliances in...
