Embodiment Construction

[0023] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention clearer and clearer, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, but not to limit the present invention.

[0024] Such as figure 1 As shown, an automatic identification method of a vehicle clutch signal disclosed by the present invention includes the following steps:

[0025] S1. Data collection, the steps include:

[0026] S11. Take time T as the cycle to continuously collect data from the vehicle CAN bus, and record the data set collected each time {P j , U j , A j , T j }, where P j , U j , A j , T j They are the engine output power, vehicle speed, acceleration, and time of acquisition data collected for the jth time; each time the data set {P j , U j , A j ,...

Abstract

The invention discloses a method for automatically identifying a vehicle clutch signal. The method comprises the following procedures: S1, data acquisition; and S2, clutch identification. The procedure of data acquisition comprises the following steps: S11, constantly performing data acquisition on a vehicle CAN bus over a cycle of time T, and recording all the acquired data sets {Pj, uj, aj, tj}; and S12, performing judgement according to the clutch level switch state acquired in the latest data acquisition process. The procedure of clutch identification comprises the following steps: S21, after extracting a standard data set, proceeding with data acquisition on the vehicle CAN bus over the cycle of time T, and recording all the acquired data sets {Pj, uj, aj, tj}; S22, whenever acquiring a data set which follows the standard data set, calculating the current engine power transmission efficiency value beta once according to the acquired data P0, Pj, aj, a0, uj and m; and S23, judging the beta values calculated after every data acquisition. By adoption of the method disclosed by the invention, the impact of driving behavior on the clutch signal can be avoided, the accuracy of overall vehicle control can be improved, and the driving behavior of a driver can be corrected.

Description

Technical field [0001] The invention relates to an automatic identification method of a vehicle clutch signal. Background technique [0002] The vehicle clutch signal is an important signal that some control functions of the vehicle need to use. Its function is: the clutch state plays an important role in the automobile engine management control system and is an important basis for engine torque control. However, in a manual transmission car, the triggering of the clutch signal is often affected by the driver's bad driving behavior. The reasons are as follows: [0003] The clutch signal of the existing vehicle triggers a level switch when the clutch pedal is fully lifted, and its value is 1 (the level switch is 1 when the clutch is lifted, and 0 when it is stepped on), so that the level output clutch lift Up signal. However, in large trucks and bus drivers, because the clutch pedal requires a large amount of force, the driver feels that the clutch is "hard". Therefore, there is a...
