The invention discloses an electronic parking control method for reducing peak current, which comprises the following steps of: switching a double-loop control model and a position closed-loop control model through a state management model, generating codes from the three models, and writing the codes to a controller to realize electronic parking control. Wherein the double-loop control model takes a current loop as an inner loop and a position closed loop as an outer loop, and PI parameter adjustment of the inner and outer loops is carried out; the position closed-loop control model only has a position closed loop and carries out position closed-loop PI parameter adjustment. According to the invention, the peak current caused when the EPP is started under the position closed-loop control can be effectively reduced, the cost of the controller in the aspect of current bearing capacity model selection can be reduced, and the response time of the EPP is prolonged.
一种减小尖峰电流的电子驻车控制方法,通过状态管理模型进行双环控制模型和位置闭环控制模型的切换,再将三个模型生成代码后刷写至控制器,实现电子驻车控制,其中:双环控制模型以电流环为内环、以位置闭环为外环并进行内外环的PI参数调节;位置闭环控制模型只有位置闭环并进行位置闭环PI参数调节。本发明能够有效降低位置闭环控制下EPP启动时造成峰值电流,可以降低控制器在电流承载能力选型方面的成本,提高EPP的响应时间。
