Definitions
- the invention relates to a device for detecting the position of a control lever of a gearbox of a motor vehicle.
- the invention relates to the detection of positions P, R, N, D and positions M +, M and M- of the control lever including a robotized gearbox generally subject to a processing unit.
- the lever is mounted with angular displacement capacity in a support housing generally fixed at the vehicle cabin.
- the lever is arranged to allow the selection of the P, R, N and D positions around an axis of rotation and the shifting around another axis of rotation for the positions M + and M-.
- This patent relates to a device for detecting the position of the control lever with the objective of detecting the movements of said lever and sending the electrical signals in a processing unit.
- the device implements a hall sensor type 3 D to indicate the various movements and positioning of the lever along the 3 axes X, Y and Z, the sensors being mounted facing a magnet.
- This solution is satisfactory but requires a positioning position of the sensor 3 D with a low tolerance to allow to know precisely the positions P, N, D and M + and M and M-.
- the problem to be solved by the invention is to simplify the detection of the positions P, R, N, D and the positions M +, M and M of a control lever by increasing certain tolerances.
- it has been designed and developed a device for detecting the positions P, R, N, D and M +, M and M of a control lever of a gearbox of a vehicle. automobile, mounted with angular displacement capacity in a support housing, said displacement being detected by means able to send electrical signals in a processing unit.
- the means consist of a single Hall sensor 2 D able to measure only the rotation of the magnetic field, said sensor being mounted opposite a double magnet to measure two rotations lever in two planes each corresponding to said positions P, R, N, D and M +, M and M-.
- the senor is mounted on a fixed part of the support case while the magnet is mounted in an arrangement of a hinge joint that has the lever.
- the double magnet is either North, South, North, or South, North, South.
- FIG. 1 is a purely schematic view showing the mounting of the magnet on the lever and its positioning relative to the hall sensor 2 D, the lever being shown in position D;
- Figure 2 is a side view corresponding to Figure 1;
- Figure 3 is a view similar to Figure 1, the lever being shown in position M;
- FIG. 4 is a side view corresponding to FIG. 3;
- FIG. 5 is a purely schematic view showing the rotation of the lever about an axis Y corresponding to the positions P, R, N, D;
- FIG. 6 is a purely schematic view showing the rotation of the lever about an axis in a YZ plane corresponding to the positions M +, M and M-;
- FIGS. 7, 8 and 9 are diagrammatic views showing the rotation of the magnet with respect to the sensor as a function of the position of the lever, namely, from the position P to the position D, FIG.
- the aim is to detect the positions P, N and D of a speed lever (1) (automatic operation) and the positions M +, M, M- of said lever (1) (sequential operation).
- the lever (1) is mounted with angular displacement capacity in a support housing (2) by means of, for example, a ball-type member (3).
- the lever (1) is arranged to be coupled to any type of actuator for selection and shifting control.
- the different positions and the different movements of the lever are detected in order to send electrical signals in a processing unit.
- the means capable of sending electrical signals into the processing unit consist of a single Hall effect sensor D 2 (4) able to measure only the rotations of the magnetic field.
- This sensor 2 D is mounted facing a double magnet (5) to measure two lever rotations (1) in two planes each corresponding to the positions P, R, N, D and M +, M and M-.
- the Hall effect sensor 2 D is for example of the Melexis 90 316 type, while the double magnet (5) can be North, South, North or South, North, South.
- the sensor 2D (4) is mounted on a fixed part of the support housing (2) while the double magnet (5) is mounted in an arrangement of the hinge joint (3).
- the goal is to detect rotation and lateral displacement of the magnet relative to the sensor.
- the positions P,, N, D of the lever are carried out around an axis of rotation, for example around the Y axis, FIG. 5, whereas the positions M +, M and M- of the lever s' perform around another axis of rotation, for example in a plane YZ, Figure 6 resulting from a tilting of the lever about the axis.
- the hall sensor 2 D detects an angular rotation as if there was only one magnet.
- Each rotation is limited to less than 150 °.
- the transition from one plane to another takes place with the translation of the double magnet which induces a 180 ° rotation of the magnetic fields.
- the lever moves along an axis YZ.
- the magnet moves in translation and mainly in rotation.
- the sensor D2 measures a rotation of the magnetic field.
- FIG. 7 For example, from position P to position D, FIG. 7, there is a rotation of the order of 26 ° of the magnet, the sensor seeing the North and South poles. From the position D to the position M, FIG. 8, there is, as indicated, a rotation of 180 ° of the magnetic fields. In position D, the sensor sees the North and South poles while in position M, the sensor sees the south and north poles. From the position M to the position M +, M-, FIG. 9, the rotation of the magnetic fields is of the order of plus or minus 7 ° for example.
