[0002] In modern automotive systems, solenoid valves are very important components of integrated brake-by-wire systems. Their functions mainly include opening and closing of hydraulic circuits, pressure boosting, pressure reducing, pressure maintaining, etc. The quality of their performance design directly affects the performance and reliability of the brake-by-wire system. Solenoid valves are typical products integrating mechanical, electrical and hydraulic systems, and their design involves mechanics, electromagnetics, fluid mechanics and corresponding control methods.

[0003] Existing solenoid valve designs require empirical designs of mechanical, electromagnetic and fluid characteristics respectively. Technical personnel in different fields need to obtain design results according to design software in their respective fields. For example, technical personnel in the field of fluid mechanics use fluid design software for empirical design of fluid characteristics, and technical personnel in the field of electromagnetics use electromagnetic design software for empirical design of electromagnetic characteristics, etc. Then, the preliminary results obtained from their respective designs are fed back and integrated, and verified through system simulation software and prototype tests.
