The invention relates generally to a biometric shifter for a vehicle, and more particularly to a biometric shifter housing a palm vein sensor for performing operating functions in the vehicle.
The statements in this section merely provide background information related to the present disclosure and may or may not constitute prior art.
Motor vehicles have been designed with increasingly advanced technologies aimed at improving the safety, efficiency, and performance of the motor vehicle. An example of such technologies includes biometric control systems. Biometric control systems pair biometric sensors with vehicle functions in order to improve ease of use/access to the vehicle. One example of a biometric control system is a fingerprint scanner used to unlock or turn on a vehicle. The fingerprint scanner senses or reads the fingerprint biometric data of a user. This biometric data is then compared to pre-registered biometric data to determine if the user is authorized to operate the vehicle. However, fingerprint scanners may have trouble detecting the biometric data of the user due to limits in the technology. Another type of biometric sensor is the vein reader sensor which detects the vein pattern of a user. The vein reader sensor is typically more reliable and faster than a fingerprint sensor. However, the vein reader sensor uses infrared emissions and reflections and thus requires a specific distance between the sensor and the operator's hand. Accordingly, there is a need in the art to provide a biometric control system that utilizes vein reader sensor technology that functions with vehicle design requirements.
A biometric shifter for a vehicle is provided. The biometric shifter includes a shifter body having an outer surface with a grip portion configured to be gripped by an operator's hand, the shifter body defining a chamber, the grip portion having an opening that communicates with the chamber, a vein reader sensor disposed within the chamber at a first distance from the opening in the grip portion, wherein the first distance is configured to optimize biometric verification of an operator's hand on the grip portion of the shifter body.
In one aspect, the biometric shifter includes a window disposed overtop the opening in the grip portion, wherein the window is transparent to infrared radiation.
In another aspect, the opening in the grip portion is free from material.
In another aspect, a location of the opening in the grip portion is configured to align the opening with the palm of the operator's hand when gripping the grip portion.
In another aspect, the first distance is approximately 50 mm.
In another aspect, the window has a longitudinal width greater than the first distance.
In another aspect, the longitudinal width of the window is approximately 100 mm.
In another aspect, the vein reader sensor is in communication with a controller having memory for storing a biometric template, and the controller is configured to compare sensor data from the vein reader sensor to the biometric template to activate at least one function if the sensor data matches the biometric template.
In another aspect, the at least one function includes unlocking the biometric shifter to allow the biometric shifter to move.
In another aspect, the at least one function includes enabling the ignition of the vehicle.

The shifter 12 includes a shifter base 16 and a shifter knob 18. The shifter base 16 is mounted within the passenger compartment of the vehicle, typically in the dashboard instrument panel or center console, so as to be accessible by an operator of the vehicle. The shifter base 16 includes an indicator panel 20 that indicates in which operating mode the biometric shifter 10 is currently engaged.
The shifter knob 18 extends out from the shifter base 16 and is moveable with respect to the shifter base 16, by pivoting, translating, or a combination of both. The shifter knob 18 includes a shifter body 22 having an outer surface 24. The shifter body 22 defines a chamber or recess 26 within the shifter body 22. The chamber 26 is free of any material and is defined by four planar side walls 27 and a bottom surface 29. In one aspect, the planar side walls 27 are angled with respect to the bottom surface 29. In another aspect, the planar side walls 27 are substantially perpendicular to the bottom surface 29. The outer surface 24 includes a grip portion 28 that is sized to be gripped by the hand of an operator of the vehicle. The grip portion 28 is disposed at a distal end of the shifter knob 18. An opening 30 is disposed in the grip portion 28 and communicates with the chamber 26. The opening 30 is preferably positioned such that an operator's hand covers the opening 30 when the operator grips the shifter knob 18. The opening 30 has a longitudinal length “L” and a transverse width “W”. In one example, the length L and width W of the opening are each at least 80 mm. In another example, the length L and width W of the opening are each at least 100 mm. In one aspect, a transparent cover or window 32 is disposed in the opening 30. The window 32 is transparent to at least infrared radiation.
The biometric sensor 14 is disposed within the chamber 26 of the shifter knob 18. In one example, the biometric sensor 14 is disposed on the bottom surface 29 of the chamber 26. The biometric sensor 14 is coincident with the opening 30. The biometric sensor 14 is a distance “D” from an imaginary plane that is coplanar with the outer surface 24. The distance D is selected to optimize the capability of the biometric sensor 14 to sense biometric data at approximately the distance D. In one aspect, the distance D is approximately 50 mm.
The biometric sensor 14 is preferably a vein reader sensor that emits infrared radiation and detects reflected radiation. The biometric sensor 14 is in electronic communication with a controller 34. The controller 34 may be packaged with the biometric shifter 10 or be a vehicle control module, such as a body control module, engine control module, transmission control module, etc. Generally, the controller 34 is a non-generalized, electronic control device having a preprogrammed digital computer or processor, memory or non-transitory computer readable medium used to store data such as control logic, instructions, lookup tables, biometric data, driver preferences, etc., and a plurality of input/output peripherals or ports. The processor is configured to execute the control logic or instructions. The controller 34 is configured to execute, or command/request execution of, various functions within the vehicle based on biometric data sensed by the biometric sensor 14. These functions may include, for example, starting the motor vehicle, unlocking the shifter knob 18 for movement out of park, activating driver preferences related to seat position, side view mirror position, etc.
For example, when an operator of the vehicle grips the shifter knob 18, the operator's palm is disposed overtop the opening 30. The grip portion 28 keeps the palm at approximately the distance D, thereby optimizing the ability of the biometric sensor 14 to sense the biometric data. The biometric sensor 14 wakes from a sleep mode and scans and detects the vein pattern of the operator's palm or fingers. The sensed vein pattern is then digitized as a template of biometric data and compared to stored biometric data templates associated with authorized operators of the vehicle. If there is a template match the controller 34 commands one or more functions. If there is not a template match the controller 34 sends an identification fail command to the vehicle.

The shifter knob 218 is moveable with respect to the shifter base 216 by translating in a longitudinal direction between various positions, including a Park position, a Reverse position, a Neutral position, and a Drive position. The shifter knob 218 further includes a Park button 220 and an unlock button 222. Pressing both the Park button 220 and the unlock button 222 allows the shifter knob 218 to be moved out of Park. The shifter knob 218 includes a shifter body 223 having an outer surface 224. The shifter body 223 defines a chamber or recess 226 within the shifter body 223. The chamber 226 is free of any material and is defined by four planar side walls 227 and a bottom surface 229. In one aspect, the planar side walls 227 are angled with respect to the bottom surface 229. In another aspect, the planar side walls 227 are substantially perpendicular to the bottom surface 229. The outer surface 224 includes a grip portion 228 that is sized to be gripped by the hand of an operator of the vehicle, similar to a computer mouse. An opening 230 is disposed in the grip portion 228 and communicates with the chamber 226. The opening 230 is preferably positioned such that an operator's hand covers the opening 230 when the operator grips the shifter knob 218. The opening 230 has dimensions similar to the opening 30.
The biometric sensor 14 is disposed within the chamber 226 of the shifter knob 218. In one example, the biometric sensor 14 is disposed on the bottom surface 229 of the chamber 226. The biometric sensor 14 is coincident or in alignment with the opening 230. The biometric sensor 14 is a distance “D” from an imaginary plane that is coplanar with the outer surface 224. The distance D is selected to optimize the capability of the biometric sensor 14 to sense biometric data at approximately the distance D. In one aspect, the distance D is approximately 50 mm. Thus, when an operator's hand grips the mouse shifter 212, the palm of the operator's hand is approximately at the distance D from the biometric sensor.
