Problems solved by technology

[0013] The purpose of the present invention is to solve the problems of the existing electric shift lever system, which learns the position of the motor corresponding to the R gear and the N gear by sensing the change in the amount of current generated by the motor , and master the positions of P and D by offsetting the learned positions of R and N, the amount of current generated by the motor changes according to the change of the load of the motor caused by the external force of the spring , the spring external force is generated by the gap between the peak and valley shape formed by each gear of the brake plate (Detent Plate) and the detent spring (Detent spring)

Abstract

The present invention relates to a position learning system for an electric shift-by-wire system, which senses changes in the load of a motor according to operations of a four-stage detent plate and adetent spring to learn positions of shift stages of the electric shift-by-wire system, the position learning system including: a sensor for sensing the current generated from the motor; and a controller for receiving current data until a shift stage P is switched to a shift stage D or the shift stage D is switched to the shift stage P from the sensor, learning positions of shift stages R and N through the received current data, and performing offset operations on the basis of the learned positions of the shift stages R and N to learn positions of the shift stages P and D.

Description

technical field [0001] The present invention relates to a position learning system of an electric shift lever system, more specifically, relates to a position learning system, the system can sense the change of the current generated by the motor to learn the motor corresponding to the R gear and the N gear position, and master the positions of P and D by offsetting the learned positions of R and N, and the amount of current generated by the motor changes according to the load of the motor caused by the external force of the spring The spring external force is generated by the gap between the peak and valley shape formed by each gear of the brake plate (Detent Plate) and the detent spring (Detent spring). Background technique [0002] The transmission is the core component of the car drive. Its function is to increase or decrease the rotational force of the engine according to the driving conditions of the car, and to transmit the power generated by the engine to the wheels. ...
