电子驻车系统P档驻车功能实现的控制方法研究

Research of Control Method for Parking Function of EPB

用电子驻车制动系统(EPB)来替代传统的手动驻车制动系统,由于其结构便利性以及数字化控制模式的优点,越来越被广泛应用。文章对EPB驻车与P档驻车之间的关系进行了研究,在EPB现有功能的基础上提出了由EPB代替P档驻车机构,实现P档驻车的新功能。详细阐述了EPB实现P档驻车及释放功能的控制逻辑及方法,并经过了台架和实车的验证。

The electronic parking brake system （EPB） takes the place of the traditional manual parking brake system due to the convenience in structure and the advantages of digital control mode, and it has been widely used. This paper studies the relationship between the EPB parking and the P parking, and proposes a new function of P parking based on the existing functions of EPB. This paper describes the control logic and method of EPB realizing P parking function, and is validated by bench and vehicle.
