Study on durability test bench of the automotive electric horn

摘要

Automotive electric horn is an indispensable electrical component of the vehicle safety system. Practical application shown again and again that by better use of the horn, drivers can reduce the operating frequency of deceleration, breaking. At the same time the system has an impact on improving the driving safety and improving the speed of the vehicle. In recent years, low-cost, long life, high reliability, durability and environmental adaptability have become the development direction of the automotive electric horn. Consequently this paper describes a study on a durability test bench of the automotive electric horn based on the industry standards and prospects, using a programmable logic controller (PLC) intelligent control module to provide an intelligent and reliable electric horn test program. After a long-term testing, the result shows that the experimental accuracy of the solution has a high accuracy and has basically reached the expected control effect. This durability test bench has a very high feasibility.
