Abstract

An adapter engages a floor-mounted shift lever of a vehicle. The adapter holds the locking detent of the shift lever down so that the lever can be moved. A robotic actuator is coupled to the adapter via a ball joint to selectively move the shift lever.

Claims

1. A device for moving a floor-mounted shift lever of a vehicle, the shift lever including an operating detent button mounted at an upper portion of the shift lever for actuation by a vehicle operator, said operating detent button being biased to an engaged position, wherein the shift lever cannot be moved, the operating detent button being movable by a vehicle operator to a disengaged position, wherein the shift lever can be freely moved, the device comprising:

a shifter adapter housing configured for fixedly mounting directly to an upper portion of the shift lever such that the shifter adapter housing holds the operating detent button in the disengaged position;

a control unit mounted in the vehicle, the control unit selectively outputting a control signal; and

a shifter actuator coupled to the shifter adapter housing, said shifter actuator being operable to move the shift lever of the vehicle in response to the control signal received from the control unit.

2. The device of claim 1, further comprising a robotic base, wherein the shifter actuator is coupled to the robotic base.

3. The device of claim 2, further comprising a proximal ball joint interconnecting the shifter actuator and base and a distal ball joint interconnecting the shifter actuator and shifter adapter housing.

4. The device of claim 3, wherein the shifter adapter housing is formed with a channel, the channel being configured for closely receiving the shift lever therein.

5. The device of claim 4, further comprising at least one clamp boltingly engageable with the shifter adapter housing for sandwiching the lever therebetween.

6. A vehicle, comprising:

a floor-mounted shift lever;

an operating detent button mounted at an upper portion of the shift lever and biased to an engaged position, wherein the lever cannot be moved, the operating detent button being movable by a vehicle operator to a disengaged position, wherein the lever can be freely moved;

a shifter adapter mounted directly to an upper portion of the shift lever such that the shifter adapter holds said operating detent button in the disengaged position;

a control unit mounted in the vehicle, the control unit selectively outputting a control signal; and

a shifter actuator coupled to the shifter adapter, said shifter actuator being operable to move the shift lever of the vehicle in response to the control signal received from the control unit.

7. The vehicle of claim 6, further comprising a robotic base, wherein the shifter actuator is coupled to the robotic base.

8. The vehicle of claim 7, further comprising a proximal ball joint interconnected to the shifter actuator and base and a distal ball joint interconnecting the shifter actuator and the shifter adapter.

9. The vehicle of claim 8, wherein the shifter adapter comprises:

a rigid housing formed with a channel, the channel being configured for closely receiving the shift lever therein.

10. The vehicle of claim 9, wherein the shifter adapter further comprises at least one clamp boltingly engageable with the rigid housing for sandwiching the shift lever therebetween.

11. A method for moving a floor-mounted shift lever of a vehicle having a lock detent button mounted at an upper portion of the shift lever, comprising the steps of:

mounting an adapter housing directly to an upper portion of the shift lever such that the adapter housing urges against the lock detent button to hold said lock detent button in a disengaged position;

providing a control unit being mounted in the vehicle, said control unit selectively outputting a control signal;

engaging a shift actuator with the adapter housing, said shift actuator being operable to move the shift lever in response to said control signal; and

actuating said shift actuator in response to said control signal received from said control unit, thereby moving the floor-mounted shift lever of the vehicle.

12. The method of claim 11, further comprising the step of providing a ball joint to interconnect the shift actuator and adapter housing.
