Embodiment 1

[0040] like Figure 1 to 3 , The disclosure of the present invention is self-learning a gear shift knob's method, it applies the shifter knob works as follows: a gear position corresponding to each of the shifter knob are provided a shift angle range, the rotation angle value of the Hall sensor of the knob, the detected rotational angle value of the angle range for each gear position comparing the detected rotational angle value corresponding to the angular range where the gear is the gear shifter knob shift information output.

[0041]Said gear self-learning method for determining the exact angle range for each gear shift position of the shifter knob, based on PC, CAN cards, boards and manipulator embodiments, wherein said host computer through the control board of the manipulator, the manipulator such that rotation of the knob can be self-learning gear shift knob for controlling the gear shift, and the host computer capable of receiving the shift knob by the CAN card Hall sensor ...

Embodiment approach

[0062] The step S1, the measured values ​​of the left dead angle X 0 And a right dead center angle value X m The method is:

[0063] Step S1.1, controlling the manipulator, at a preset fixed rotation torque of the knob of the shifter knob counterclockwise, until the Hall sensors to collect at the angle value is maintained within a predetermined length of time when the same angle value, the recording of the angle value, and this step is repeated a plurality of times S1.1;

[0064] Step S1.2, controlling the manipulator, at a preset fixed rotation of the torque knob shifter knob clockwise, until the sensors to collect the Hall angle is maintained at a value within a predetermined length of time when the same angle value, the recording of the angle value, and this step is repeated a plurality of times S1.2;

[0065] Step S1.3, when decreasing direction (V) of the Hall sensors to collect the value of the angle in the clockwise direction, the maximum value of said step S1.1 if the plur...

Embodiment 3

[0070] In the above-described first embodiment or the second embodiment based on the present third embodiment also adopts the following preferred embodiments:

[0071] In step S3, the preset value of the empty window angle α between 0.2 ° to 0.5 °.

[0072] Wherein, preferably: the preset value of the empty window angle α is 0.3 °.

[0073] In order to better illustrate the present invention, the gear Advanced self-learning method, it is a random selection of sample shifter knob (the shift knob's parameters such as the one exemplified above), respectively, using two self-learning method a background of the prior art gear self-learning method, namely: see Figure 4 , Only the self-learning the position of the P range, P range position and then as a reference to calculate the cumulative another gear position, a shift stroke, another gear of the present invention is self-learning method, to obtain two different gear angles range, and then compared with the actual gear angular range, p...

Abstract

The invention discloses a gear position self-learning method of a knob shifter. By detecting the left dead point position and the right dead point position of the knob shifter, the measured left dead point angle value X 0 and right dead center angle value X m As a benchmark, the gear angle range of each gear of the knob shifter is calculated through self-learning, which can eliminate the installation error of the knob shifter and the error of the Hall sensor itself to the greatest extent, and improve the gear position obtained by self-learning The accuracy of the angle range, thereby improving the accuracy of gear recognition and judgment of the knob shifter, and ensuring driving safety; and, the present invention can also measure the left dead center angle value X of the knob shifter through step S1 0 and right dead center angle value X m , to judge whether the limit pins of the knob shifter at the left and right dead center positions have been installed correctly, so as to prevent workers from mis-installing and missing-installing.

Description

Technical field [0001] The present invention relates to a gear the shifter knob self-learning method. Background technique [0002] Conventional shift position by a mechanical fastener is a change in the information transmitted to the transmission gear, the shift knob is an electrical signal via the bus line and the hard to pass information to the transmission gear. As a function of cases involving cars with security, how to correct the position signal transmitted to the transmission, the focus needs to be considered when designing the shifter knob. To achieve this goal, typically mounted on a rotary shaft shifter knob Hall sensor, i.e. for detecting the angle of the rotation shaft of the shifter knob, and preservation of this angle of advance angular range gear good alignment, so that the angle corresponding to the current draw gear. To ensure detection accuracy when the current angle, the right angle gear gear range is determined correct premise. Right angle gear range is reaso...
