本论文首先介绍了电子驻车制动系统的应用现状、原理、优点与发展趋势。然后详细描述了电子驻车制动系统的硬件总体方案的设计。按照系统的硬件要求，设计了汽车方向盘转角传感器并对其他部件的传感器进行了研究选取，然后对它们进行了安装设计。最后对仿真实验台的整体设计进行了装配。
电子驻车制动装置与传统的手动驻车制动装置相比，不论在汽车起步，还是停驶驻车时，驾驶员都不需要再操作手动制动手柄，这大大降低了驾驶员的操作难度，提高了驾驶的舒适性和制动性能，同时也提高了驾驶的安全性、有利于环保，而且对电子行车制动系统的开发起到推进作用。所以说，电子驻车制动系统的开发与检测具有极其重要的意义。

Title Structural design of the electronic parking brake test bed
Abstract
The system of electronic parking brake(EPB) is a type of the
automobile’s braking system controlled-by-wire, is also the development
direction of the vehicle’s braking system. It replaces the
pull-tight-wire and brake equipment of traditional hand-brake system by
the wire, replaces the traditional brakes by electronic brakes, which
controlled the magnitude of vehicle parking-strength and dynamically
distribute parking-strength on each wheel combined the car environment of
condition with the electronic control unit(ECU). This EPB have the function
of Hill Starting Aid(HAS) and intelligences of parking/relief function.
This system is the innovation of the vehicle parking system. This text
mainly researches on the EPB design of hardware circuits.
This paper first introduces the application of electronic parking
brake system, principles, advantages and development trends. Then a
detailed description of the electronic parking brake system hardware
design of the overall program was discribed. In accordance with the
system's hardware requirements, designed a car steering wheel angle sensor
and other parts of the sensors were selected, and then installed them
designed. Finally, finished the overall design of the simulation test bed
assembly.
Compared the EPB with traditional hand braking system, in spite of in
the automobile’s staring, or the parking the car, the driver do not need
to operate the handle braking pole ,this consumedly reduce the driver’s operation difficulty, raise the drive-comfort and raise the
brake-function, also raised the safety ,be advantageous to the
environmental protection, and have the propulsion to the brake-by-wire
system. So, the research on design of hardware and detection in electronic
parking brake system has very important meaning.
Keywords ： Electronic Parking , Test Bench, Structural design
