Abstract
A shift control method of an electronic shift lever may include detecting a collision of a vehicle when the vehicle is in an ignition-on state, detecting a shift range of the electronic shift lever, and preventing shifting by interrupting delivery of a signal for changing the shift range to a transmission, when the signal for changing the shift range is detected within a predetermined time after the detection of the collision.
Claims6
A shift control method of an electronic shift lever, comprising:
- detecting, by a collision sensor or an airbag sensor, a collision of a vehicle when the vehicle is in an ignition-on state;
- detecting, by a lever sensor, a shift range of the electronic shift lever immediately before the collision;
- detecting, by the lever sensor, a shift range of the electronic shift lever immediately after the collision;
- and
- interrupting, by control of a Transmission Control Unit (TCU), a shifting process so that a signal for changing the shift range, which is generated immediately after the collision, is not delivered to a transmission, when the shift range immediately before the collision and the shift range immediately after the collision are different within a predetermined time after the detection of the collision.
