Embodiment 1

[0040] Such as Figure 1 to Figure 3 As shown, the present invention discloses a gear self-learning method for a knob shifter. The working method of the knob shifter is as follows: a gear angle is set for each gear of the knob shifter. Range, the rotation angle value of the knob is detected by the Hall sensor, and the detected rotation angle value is compared with the angle range of each gear position. The gear position corresponding to the gear angle range of the detected rotation angle value is the knob shifter Output gear information.

[0041]The gear self-learning method is used to determine an accurate gear angle range for each gear of the knob shifter, and it is implemented based on a host computer, a CAN card, a board and a manipulator, wherein the host computer can pass The board controls the manipulator so that the manipulator can rotate the knob shifter for gear self-learning to control the shifting knob, and the host computer can receive the knob shifter through th...

Embodiment approach

[0062] In the step S1, the angle value X of the left dead center is measured 0 and right dead center angle value X m The method is:

[0063] Step S1.1, controlling the manipulator to rotate the knob of the knob shifter counterclockwise with a preset fixed torque until the angle value collected by the Hall sensor is maintained at For the same angle value, record the angle value, and repeat the step S1.1 multiple times;

[0064] Step S1.2, controlling the manipulator to rotate the knob of the knob shifter clockwise with a preset fixed torque until the angle value collected by the Hall sensor is maintained at For the same angle value, record the angle value, and repeat the step S1.2 multiple times;

[0065] Step S1.3, when the decreasing direction (V) of the angle value collected by the Hall sensor is the clockwise direction, if the maximum value among the multiple angle values ​​recorded in the step S1.1 appears At least three times, then record the maximum value as the left...

Embodiment 3

[0070] On the basis of the above-mentioned embodiment 1 or embodiment 2, this embodiment 3 also adopts the following preferred implementation modes:

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

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

[0073] In order to better illustrate the advancement of the gear self-learning method of the present invention, a sample of a knob shifter is selected at random now (the parameters of the knob shifter are as described in the above-mentioned example 1), and two kinds of self-learning methods are used respectively. , a kind of existing gear self-learning method described in the background technology, that is: see Figure 4 , only self-study the P gear position, and then use the P gear position as a benchmark to calculate other gear positions according to the accumulation of the shifter stroke. The other is the gear self-learning method of the present in...

Abstract

The invention discloses a gear self-learning method of a knob shifter. a left dead center position and a right dead center position of the knob shifter are detected, taking the measured left stoppingpoint angle value X0 and the right stopping point angle value Xm as reference, the gear angle range of each gear of the knob shifter is calculated through self-learning, the installation error of theknob shifter and the error of the hall sensor can be eliminated to the maximum degree, so that the accuracy of the gear angle range obtained by self-learning is improved, so that the accuracy of the gear position recognition and judgment of the knob shifter is improved, and the driving safety is guaranteed; moreover, whether the left stopping point angle value X0 and the right stopping point anglevalue Xm of the knob shifter can be measured through the step S1, whether the limiting pins of the knob shifter at the left stopping point and the right stopping point are correctly installed or notis judged so as to prevent the workers from being misloaded and neglected.

Description

technical field [0001] The invention relates to a gear position self-learning method of a knob shifter. Background technique [0002] The conventional shifter transmits the gear position information to the transmission through the mechanical position change of the zipper, and the knob shifter transmits the gear position information to the transmission through the electrical signal of the bus and hard wires. As a functional part related to the driving safety of the car, how to transmit the correct gear signal to the transmission is the key point to be considered in the design of the knob shifter. In order to achieve this goal, a Hall sensor is usually installed on the rotary shaft of the knob shifter to detect the rotation angle of the rotary shaft, that is, the shifter knob, and compare this angle with the gear angle range saved in advance, so that Get the gear corresponding to the current angle. When ensuring the current angle detection accuracy, the correct gear angle ra...
