The invention discloses a motor zero angle determination method and device, an electro-hydraulic braking system and electronic equipment, and the method comprises the steps: determining target pressure information in a pressure supply unit based on target current information and first preset mapping information of a motor, under the condition that difference information between the initial pressure information and the target pressure information meets a first preset condition, initial zero angle information of the motor is adjusted, and updated zero angle information is obtained; and determining updated pressure information in the pressure supply unit based on the updated zero angle information under the target current information, and determining the updated zero angle information as target zero angle information of the motor under the condition that the updated pressure information meets a second preset condition. According to the embodiment of the invention, redundancy check can be accurately and quickly carried out on the accuracy of the initial zero angle of the motor, calibration is carried out, and the accuracy and precision of the zero angle of the motor rotor are improved.

    本发明公开一种电机零位角度确定方法、装置、电液制动系统及电子设备,该方法包括基于电机的目标电流信息和第一预设映射信息,确定压力供应单元中的目标压力信息,在初始压力信息和目标压力信息间的差异信息满足第一预设条件的情况下,对电机的初始零位角度信息进行调整,得到更新零位角度信息;在目标电流信息下,基于更新零位角度信息,确定压力供应单元中的更新压力信息,并在更新压力信息满足第二预设条件的情况下,将更新零位角度信息确定为电机的目标零位角度信息。利用本发明公开实施例可以准确、快速地对电机初始零位角度的准确性进行冗余校验,并进行校准,提高电机转子零位角度的准确性和精度。
