The shift lever 72 is disposed in a ball pivot 78 and coupled to a longitudinally oriented shaft 80 which is supported by various mounting members or brackets and bearings 82 which allow it to translate fore and aft and rotate about its axis. In the neutral position of the shift linkage 70 illustrated in FIG.
The outputs of the first Hall effect sensor 96 and the second Hall effect sensor 98 are fed directly to the application specific integrated circuit 44 which may be formed and assembled integrally with the sensors 96 and 98 into a unitary device.
Alternatively, a single arc magnet or ring and a proximate single three dimensional 3D Hall effect sensor may be utilized in place of the two rings 92 and 94 and the two one dimensional 1D Hall effect sensors 96 and It will be appreciated that the first and second arc magnets or rings 92 and 94 and the associated Hall effect sensors 96 and 98 may be mounted within the transmission housing 22 , through the transmission housing 22 or at any convenient location where the rings 92 and 94 may be attached to the shaft 80 and the sensors 96 and 98 mounted proximately.
For example, they may be mounted within or near the bracket or bearing 82 illustrated in FIG. Here, the first arc magnet or ring 92 is remote or spaced from both the first and the second Hall effect sensors 96 and 98 and the second arc magnet or ring 94 is in proximate, sensed relationship with the first Hall effect sensor Rotation of the shaft 80 and the second arc magnet or ring 94 adjacent the first Hall effect sensor 96 changes or modulates the magnetic field strength sensed by the first Hall effect sensor 96 and this information is utilized by the application specific integrated circuit 44 to provide a data signal indicating the absolute, current gear shift position, as described more fully below.
Here, the second arc magnet or ring 94 is remote or spaced from both the first and the second Hall effect sensors 96 and 98 and the first arc magnet or ring 92 is in proximate, sensed relationship with the second Hall effect sensor Rotation of the shaft 80 and the first arc magnet or ring 92 adjacent the second Hall effect sensor 98 changes or modulates the magnetic field strength sensed by the second Hall effect sensor 98 and this information is utilized by the application specific integrated circuit 44 to provide a data signal indicating the absolute, current gear shift position, as described more fully below.
Referring now to FIG. It should be appreciated that the translations and rotations presented in FIG. It should also be appreciated that although the shift linkage 70 described herein functions with first selection lateral motion of the shift lever 72 followed by shift longitudinal motion and first rotational motion of the shaft 80 and the magnet rings 92 and 94 and then longitudinal motion , the invention also encompasses a shift linkage 70 in which the shaft 80 and the magnet rings 92 and 94 first move longitudinally and then rotate in response to motion of the shift lever Note, first of all, that for all neutral positions, the duty cycle output values for both the sensors 96 and 98 are identical, thus providing a useful integrity check on system and sensor operation.
Second of all, in both forward positions in the shift gate pattern 76 , selecting, for example, reverse, first, third or fifth gears, as illustrated if FIG. From this graph, as well as the data of FIG. It should be appreciated that the gear absolute position sensor assembly 40 of the present invention provides and enables several benefits and features. For example, it supports engine start-stop applications inasmuch as they require neutral position detection.
The invention improves shift quality and reduces driveline clunk by facilitating the pre-synchronization of the driveline.
Additionally, matching of the speed of the engine output and transmission input, which requires absolute gear position and the anticipated gear, is possible. Torque management which may reduce transmission mass and complexity is also possible. Remote, i. Furthermore, the invention may be utilized to reduce or substantially eliminate abuse of the transmission as it may be utilized to sense and prevent a potentially abusive operational event.
Finally, the invention provides full diagnostic capability, for example, short to power, short to ground and open circuit.
The description of the invention is merely exemplary in nature and variations that do not depart from the gist of the invention are intended to be within the scope of the invention. Such variations are not to be regarded as a departure from the spirit and scope of the invention.
