Claims13
A shift lever apparatus comprising:
- a rotation knob which is rotatable in a shift lever case to select a gear stage, provides shift feeling by a shift feeling unit during rotation, and has a null section at a point at which shift feeling is provided;
- a friction device mounted in the shift lever case and including a friction rod that generates frictional force in a response that the friction device is moved to the rotation knob to contact with the rotation knob during an operation thereof;
- and
- a controller configured to receive positional information related to the rotation knob, to determine current manipulation of the rotation knob to be malicious manipulation in a response that the rotation knob is maintained in the null section or repeatedly enters the null section, and to control the friction device to make the friction rod contact with the rotation knob in a response that the current manipulation is determined to be malicious manipulation.
