Development And Test Of Electronic Parking Brake Assembly

As of 11/31/2016,the vehicle ownership of China has exceeded 200 million,and is still at an annual rate of about 30 million high-speed growth,There is no doubt that China has become the world's largest automobile production and marketing country,the Asia-Pacific region,specifically the Chinese market has been focused on by the car manufacturers,In the era of rapid development of the car security has been more and more attention.The security of a car has been the primary factor in the consideration of purchasing.In the field of automotive brake,due to the application of electronic parking,such as steep slope assistance,emergency braking and other important active safety function,reducing the probability of driver errors and traffic accidents.At the same time,the automotive brake electric control has also been the necessary condition of automatic driving technology.This essay introduces about the development and testing of automotive electronic parking brake,including the function and structure of the electronic parking brake system,the structure and function of the brake actuator,and the development process.In order to improve the entire development process also had added the assembly test methods and test standards in it.First of all,the function of the electronic parking system,which has been divided into two parts: basic braking and active safety braking had been described,Then in order to achieve a complete description of the structure of each corresponding function,having the structure explanation of this two parts,Then the second chapter describes how these functions are implemented,in this chapter,the control strategy for the calculation and design of the implementation function is described in detail.After the completion of the pre-strategic planning and implementation,the third chapter introduce the main implementing agencies MGU and brake calipers development,with design renderings.Finally,after the completion of the software and hardware development,this article introduced its test,mainly for the test method and acceptance criteria of the two parts,also the test items explained one by one.The data,which involved in acceptance criteria combined with the actual use of the situation,have a further explanation,relevance and importance of the author's understanding of the interpretation.In the introduction of electronic parking brake,mainly focus on the safety-related functions and extended functions.Firstly,is to combine the current trend of the development of automotive safety functions,secondly is the summary of work process experience,at the same time learn from foreign advanced company's development process and indicators of the product controlling experience in process.Hope through the completion of the paper process,can sort out the entire development process of electronic parking brake systematically,to avoid unnecessary process and time waste.
