Abstract
A haptic shift device for use in shift-by-wire systems in vehicles. The haptic shift device includes a shift lever manipulatable by a user. At least one sensor detects a position of the shift lever, and a transmission gear of the vehicle is caused to be changed based on the position of the shift lever. At least one electrically-controlled actuator outputs a force on the shift lever. In some embodiments, the shift lever is moveable within a pattern and is blocked from areas outside the boundaries of the pattern. The actuator(s) can be active or passive, and/or a variable mechanical gate can be used to implement the pattern. Provided shifting modes can include automatic, manual, and/or sequential modes. Other shifting modes can also be provided.
