Problems solved by technology

[0006] The rotation of the brake plate as described above may cause a problem that the shift gear is changed differently from the driver's intention
In particular, when the target shift gear is the P gear, there is a possibility that the vehicle rolls away as the P gear is released, and thus there is a potential safety accident.

Abstract

A controlling apparatus for an electric shift-by-wire system is disclosed. The apparatus includes a shift stage sensor detecting information on a target shift stage according to the operation of the shift lever; a position sensor detecting information on a position of the motor; and a controller configured to receive the detected information from the shift stage sensor and the position sensor, when the target shift stage is a P stage, determine whether the P stage is likely to be released using the position information of the motor, and when it is determined that the P stage is likely to be released, limit rotation of the motor.

Description

technical field [0001] The present invention relates to a control device for an electric shift lever system and a control method thereof, and more particularly, to a control device for an electric shift lever system capable of preventing the P shift from being released differently from the driver's intention after shifting to the P position. Control Method. Background technique [0002] Unlike a mechanical shifter system that uses a mechanical link structure such as a cable, an electric shifter system uses electrical signals to perform shifting. Specifically, the electric shift lever system, which is a system that rotates a motor to switch gears by transmitting shift lever operation information by an electric signal, has small shift shock and vibration, so vehicles employing the system are gradually increasing. [0003] In addition, the electric shift lever system uses the brake plate and brake spring connected to the electric motor to perform the shifting. Specifically, w...
