The invention discloses a speed loop control automatic parking method for an electric vehicle driving system. The method comprises the following steps: a driving system obtains work condition information and automatic parking information provided by a VCU, and the work condition information comprises at least one of a road surface work condition and a road work condition; wherein the automatic parking information comprises at least one of an automatic parking function enabling sign and an automatic parking rotating speed; the driving system acquires self working condition information; the driving system judges whether the parking function works in a common mode or a demand mode according to the obtained information; and the driving system controls the vehicle speed to reach the vehicle speed required by the automatic parking function through the speed ring. The automatic parking function of the electric automobile is achieved on the basis that hardware cost is not increased, the automobile acceleration, deceleration and parking functions needed by automatic parking are achieved through the rotating speed of the electric driving system, the beneficial effect of being rapid and stable in response is achieved, meanwhile, the automobile can be rapidly stopped under emergency conditions through automatic protection of the electric driving system. Higher safety performance is realized.
本发明公开了一种电动汽车驱动系统速度环控制自动泊车方法,包括:驱动系统获取VCU提供的工况信息和自动泊车信息,工况信息包括路面工况和道路工况中的至少一种,自动泊车信息包括自动泊车功能使能标志和自动泊车转速中的至少一种;驱动系统获取自身工况信息;驱动系统根据获取的信息,判断泊车功能工作于普通模式还是需求模式;驱动系统利用速度环控制车速达到自动泊车功能所需的车速。在不增加硬件成本的基础上实现了电动汽车的自动泊车功能,通过电驱动系统转速来实现自动泊车所需的车辆加速、减速以及停车功能,具有响应快速平稳的特点,同时,通过电驱动系统自动保护使得汽车在紧急情况下能够快速的停止,具备更强的安全性能。
