Problems solved by technology

[0006] 1. In the above-mentioned first method, two different universal joints need to be manufactured. It is not easy to install and debug, but the scale used is easily affected by external factors and changes the error range, resulting in uncertainty of the measurement results. Installation, debugging and It is difficult to maintain, the error range is easy to change, and the false positive rate is high;
[0007] 2. In the second method, since the mechanical switch is directly contacted, the operation interval is difficult to determine, installation, debugging and maintenance are difficult, the error range is easily changed, and the false alarm rate is high

Embodiment 1

[0101] As shown in the figure, a gear information processor, the gear information processor DW includes an information processing module 1 and a human-computer interaction interface 2 connected thereto, a power adapter 3 and an input and output interface 4;

[0102] The human-computer interaction interface 2 is composed of an 8-segment "Day."-shaped LED digital display tube 21 and an operation button 22; the 8-segment "Day."-shaped LED digital display tube 21 is used to display the gear position measurement results respectively , working status, installation and operation guidance, in which the "day" shaped LED digital display tube is used to display the operating status of the device and / or other characters (for example, the LED digital display tube displays "1", "2", "3", "4 ", "5", "0", and "6" indicate that the gear positions of the test vehicle running state are 1st gear, 2nd gear, 3rd gear, 4th gear, 5th gear, neutral gear, reverse gear, and other characters such as: In...

Embodiment 2

[0114] A system for judging the current gear of a motor vehicle, Figure 4 It is a schematic diagram of the system structure for judging the current gear position of a motor vehicle. The system includes the gear position information processor DW described in Embodiment 1, the permanent magnetic marker NS and the Hall sensor H; the permanent magnetic marker NS and The installation position of the Hall sensor H is a space measurement triangle; there are many different installation methods according to the number of permanent magnetic markers NS and Hall sensor H used and the specific vehicle conditions.

[0115] The permanent magnetic marker NS is fixedly installed on the shift lever A and changes with the change of the shift lever, so that the magnetic flux density passing through the Hall sensor H can change with the change of the shift lever. The marker NS can move along the axial direction of the shift lever A before it is fixed on the shift lever A. When installing, first f...

Embodiment 3

[0131] A method for judging the current gear position of a motor vehicle is to use the system for judging the current gear position of a motor vehicle described in Embodiment 2 to realize the method for judging the current gear position of a manual transmission motor vehicle. The method is based on the nature of the trilateral relationship of a triangle, Analyze and judge by using the measurement triangle formed by the magnetic mark fixed on the shift lever and changing with the change of the shift lever and the measurement value of the Hall sensor fixed around the shift lever but not changing with the change of the shift lever , at least one such measurement triangle is required. In order to be more accurate and reliable, multiple similar measurement triangles can be set to obtain the real-time gear position of the motor vehicle gearbox; it judges the current gear position of the motor vehicle For the method flow, see Figure 10 , the main steps are as follows:

Abstract

The invention discloses a gear information processor, a system for determining a current gear of a motor vehicle and a method for determining a current gear of a motor vehicle. The gear information processor comprises an information processing module, a human-machine interaction interface, a power adapter, and input and output interfaces, wherein the human-machine interaction interface, the poweradapter, and the input and output interfaces are connected with the information processing module. The input and output interfaces are used for providing interfaces of signal inputting, result outputting, and connection services for the information processing module and consist of a hall sensor input parallel interface, a gear value parallel output interface and a bus type asynchronous serial on-line communication interface. Besides, the system for determining a current gear of a motor vehicle is composed of a gear information processor, a permanent-magnet magnetic marker and a hall sensor; and the permanent-magnet magnetic marker and the hall sensor are installed in a spatial measurement triangular shape. The system having stable performances is capable of determining a current gear of amanual-shift-gear motor vehicle accurately and reliably; the installation becomes convenient and rapid; and debugging and daily maintenance are carried out conveniently.

Description

technical field [0001] The invention relates to a gear information processor of a motor vehicle, a system for judging the current gear of a manual gear transmission of a motor vehicle and a method for judging the current gear of a manual gear transmission of a motor vehicle. Background technique [0002] At present, in the process of domestic motor vehicle driver's driving skills test, the test vehicles used are almost all manual transmission vehicles, and the manual transmission vehicles on the market do not have automatic detection parts for detecting how many gears the driver is in during driving. Therefore, the vehicle used for the test is obtained through legal and reasonable transformation of the motor vehicle purchased from the market, and the detection of gear information is realized through the following two methods: [0003] 1. Utilize the scale principle and project the detection point onto the sensor array through the universal joint (such as Figure 13-1 ), so a...
