Controller arrangement position design method based on wiring harness cost and weight

Abstract

The invention relates to a controller arrangement position design method based on wiring harness cost and weight. The method includes the steps of 1, according to arrangement positions of a sensor and an actuator and surrounding environment data, completing wire harness 3D design, and confirming a segmentation scheme; 2, completing the design of an electrical schematic diagram of the system according to the interface information files of the sensor, the actuator and the controller; 3, inputting basic information; 4, completing the receipt of the plane topology of the wire harness, and inputting the length information of each branch and trunk; 5, inputting the lead specifications, the loop number and the starting points of the sensor, the actuator and the controller; 6, performing parameter configuration; 7, performing automatic calculation to obtain an optimal controller arrangement position; 8, checking whether an output result meets requirements or not by combining actual environment data; and 9, if not, amplifying the optimal coefficient or adjusting the analysis interval, and repeating the steps 8 and 9 until the requirements are met. According to the method, the controller can automatically generate the optimal arrangement area, the manual analysis time is saved, and the cost and the weight of the whole vehicle are optimized.

Description

technical field [0001] The invention belongs to the technical field of automobiles, in particular to a method for designing controller layout positions based on the cost and weight of wiring harnesses. Background technique [0002] With the continuous increase of automobile functions, the required electrical appliances are also increasing. The wiring harness of the whole vehicle provides power and signal paths for these electrical appliances, which is becoming more and more complicated, and the cost and weight are also rising. [0003] Electrical appliances can be roughly divided into three categories: sensors, controllers, and actuators. Sensors and actuators are limited by their functions, and their arrangement positions are basically fixed, while controllers can be arranged relatively freely. In the past, the layout scheme of the controller was more to consider the feasibility of the space dimension and the assembly operation dimension, and did not demonstrate the impact...
