Abstract

The invention discloses a reserve parallel connection method of automotive electronic equipment. The reserve parallel connection method comprises the following steps: determining the demand reliability of a system according to the safety requirements for the automotive electronic equipment and calculating the reliability of modules and the system reliability of the automotive electronic equipment after reserve parallel connection; fusing the failure rate of each module into the system reliability and establishing a reserve parallel connection reliability design model of the electronic equipment through taking the reliability of the automotive electronic equipment as a satisfied condition based on development cost and minimum size; obtaining the relation between the reserve parallel connection quantity of the modules and the demand reliability; establishing an evaluation optimization model based on index variable factor weighing; solving the reserve parallel connection reliability design model based on the index variable factor weighing and obtaining an optimized reserve parallel connection scheme of the automotive electronic equipment. According to the method disclosed by the invention, the reliability of the automotive electronic equipment is truly guaranteed, and meanwhile, both the cost and the space are saved.

Description

technical field [0001] The invention relates to the technical field of automotive electronic equipment, in particular to a storage parallel connection method for automotive electronic equipment. Background technique [0002] Automotive electronic equipment is the general term for car body electronic control devices and vehicle electronic control devices, including engine control, transmission system control, brake control, chassis control and instrument air conditioning five module devices. The safety and reliability of the car are the most important indicators of the car. The reliability of the car depends to a large extent on the reliability of the car's electronic equipment. The reliability of the car's electronic system directly affects the working state of the car. Due to the limitations of production technology, materials and performance, the reliability of each module in the automotive electronic equipment cannot be greatly improved. In order to further improve the sa...
