Problems solved by technology

However, at present, fuel vehicles rarely deploy vehicle gear recognition sensors. The installation of gear recognition sensors will inevitably increase the cost of vehicle manufacturing, and after the gear recognition sensors are installed, the vehicle gear data cannot be collected after the gear recognition sensors fail. , making it impossible to obtain the driving behavior data of the vehicle driver

Abstract

The invention discloses a fuel vehicle gear recognition method and system. By obtaining the output shaft speed of the fuel vehicle gearbox and the engine speed; calculating the ratio between the gearbox output shaft speed and the engine speed; calculating the ratio between the gearbox output shaft speed and the engine speed The arc tangent function value of ratio; Carry out clustering training to described arc tangent function value by K-means algorithm, obtain clustering model; Bring the arc tangent function value of the ratio of fuel vehicle gearbox output shaft speed and engine speed into clustering A class model that identifies vehicle gears. The invention solves the problem in the prior art that the fuel vehicle does not deploy a gear sensor and cannot identify the vehicle gear, which increases the cost of the gear sensor. The invention proposes a vehicle gear recognition method and system that can On the premise of not adding hardware devices, it can effectively identify the gear status information of the vehicle.

Description

technical field [0001] The invention belongs to the technical field of automobile control, in particular to a fuel vehicle gear recognition method and system. Background technique [0002] Vehicle-machine communication devices such as Tbox can collect various vehicle signals from vehicles, and based on the collected vehicle driving data, the driving behavior data of vehicle drivers can be extracted. The analysis of driving behavior data can help OEMs optimize road test specifications, improve vehicle design, and help drivers optimize driving behavior to achieve energy saving and emission reduction. [0003] Vehicle gear data is an important feature data for the analysis of vehicle driving behavior. For the extraction of certain driving behaviors, the gear information of the vehicle must be collected. However, at present, fuel vehicles rarely deploy vehicle gear recognition sensors. The installation of gear recognition sensors will inevitably increase the cost of vehicle man...
