Title:
ELECTRONIC PARKING GEAR POSITION SELF-LEARNING METHOD AND IMPLEMENTATION METHOD
Document Type and Number:
WIPO Patent Application WO/2022/095445
Kind Code:
A1
Abstract:
An electronic parking gear position self-learning method and an implementation method. The self-learning method comprises the following steps: setting respective position reference values of a driving motor and/or a pawl at an unlocking end and a parking end according to design parameters of a parking system (S110); when entering a self-learning proceeding state, performing position self-learning of the driving motor and/or the pawl when the driving motor and/or the pawl are/is at the unlocking end and the parking end, to obtain position self-learning values of the driving motor and/or the pawl when the driving motor and/or the pawl are/is at the unlocking end and the parking end (S120); and determining target positions of the driving motor and/or the pawl at the unlocking end and the parking end according to the position self-learning values and the position reference values (S130). According to the self-learning method, learning concerning the unlocking end and the parking end is performed at the same time, and a control position is bidirectionally determined according to a learning angle; the two ends share the problem of size chain error accumulation, such that the control accuracy is improved.
