Embodiment 1

[0095] Please refer to Figure 2-4 , the first embodiment of the present invention is: a vehicle gearbox gear recognition method, this method only relies on the time stamp, engine speed, gearbox output shaft speed and clutch pedal stepping state these data can be directly collected by the data bus, that is Gearbox gear can be identified.

[0096] This method analyzes the clutch-free data (sample data in which the state of the clutch pedal is not stepped on) and the data with clutch (sample data in which the state of the clutch pedal is stepped on).

[0097] Such as figure 2 As shown, the transmission gear recognition method based on clutch-free data includes the following steps:

[0098] S101: Collect sample data within a preset first time period, the sample data includes time stamp t, engine speed ω e , Gearbox output shaft speed ω t and clutch pedal stepping state c; that is, through the data bus (such as CAN bus) according to the preset collection frequency (such as 1H...

Embodiment 2

[0159] This embodiment is a computer-readable storage medium corresponding to the above-mentioned embodiments, on which a computer program is stored, and when the program is executed by a processor, the following steps are implemented:

[0160] Collecting sample data within a preset first time period, the sample data including time stamp, engine speed, transmission output shaft speed and clutch pedal depression state;

[0161] Obtain the sample data where the state of the clutch pedal is no pedaling, and obtain the sample data of no clutch signal;

[0162] According to the gearbox configuration information, the operating gears of the clutch-free signal sample data are pre-marked, and the gearbox configuration information includes the number of gears of the gearbox, the transmission ratio of each non-neutral gear, and the neutral idle time engine speed;

[0163] According to the pre-marked operating gears of the clutch-free signal sample data, the first prior probability of ea...

Abstract

The invention discloses a vehicle gearbox gear identification method and a storing medium. The vehicle gearbox gear identification method comprises the following steps: according to the configurationinformation of a gearbox, pre-labelling an operating gear without clutch signal sample data; according to the pre-labelling result, calculating the prior probability and probability distribution of all gears on the condition of without a clutch signal; calculating the posterior probability of all gears, and selecting the gear corresponding to the maximum value as the gearbox gear identification result on the condition of without the clutch signal; according to the gear identification result on the condition of without the clutch signal, pre-labelling the operating gear with the clutch signal sample data; according to the pre-labelling result, calculating the probability distribution under semi-linkage; calculating the prior probability of all gears and semi-linkage on the condition of withthe clutch signal; and calculating the posterior probability of all gears and the semi-linkage, and selecting the gear corresponding to the maximum value as the gearbox gear identification result onthe condition of the with the clutch signal. With adoption of the vehicle gearbox gear identification method, simple, efficient, precise and reliable identification to the operating gear can be realized.

Description

technical field [0001] The present invention relates to the technical field of vehicle gear position identification, in particular to a vehicle transmission gear position identification method and a computer-readable storage medium. Background technique [0002] In the prior art, the position of the shift fork shaft of the operating mechanism is detected by physical means such as sensing type, contact type, and voltage mutual induction type to identify the gear position, such as a multi-gear gear with the publication number CN101783648A A high-speed motor gear recognition device and its recognition method, a manual transmission gear recognition device with a publication number of CN202418544U, and a simple motor gear recognition device based on voltage mutual induction technology with a publication number of CN202798576U. However, this needs to add other additional detection elements or devices on the corresponding parts, which increases the equipment cost. Contents of the...
