specific Embodiment approach 1

[0028] Specific implementation mode one: combine figure 1 To describe this embodiment,

[0029] A vehicle data processing system for analyzing driving behavior, comprising:

[0030] CAN data acquisition module 1, records a collection process as a sampling cycle, periodically collects vehicle running status data; if no data is collected, it is recorded as missing data, and the CAN data collection module sends the collected status data to the abnormal data judgment module ;

[0031] Health data includes the following categories:

[0032] The first type of data: automatic gear neutral state signal, brake pedal switch signal, engine speed signal for driving behavior analysis, clutch switch signal, accelerator pedal opening signal, engine exhaust brake signal, engine brake signal, slow speed Engine brake signal, engine coolant temperature signal, engine oil pressure signal, engine intake manifold temperature signal, engine intake manifold pressure signal, gear status signal, lon...

specific Embodiment approach 2

[0052] A vehicle data processing system for analyzing driving behavior described in this embodiment further includes:

[0053] The hard-line data collection module 4 records a collection process as a sampling period, periodically collects the manual gear neutral state signal; and sends the signal to the data processing module;

[0054] The data processing module also includes the processing of the manual gear neutral state signal, as follows:

[0055] For the case of the MT model, if the data loss of the neutral state signal of the dynamic gear is greater than or equal to 1 sampling period, send DM1 information;

[0056] For the case of the vehicle equipped with AMT, it will not be dealt with.

[0057] The hard wire is a communication signal wire different from CAN. There are mainly two forms of analog signals and CAN digital signals for the automotive electronic control unit to obtain signals. In general, analog signals are collected through hard wires.

[0058] Other mod...

specific Embodiment approach 3

[0060] A vehicle data processing system for analyzing driving behavior described in this embodiment further includes:

[0061] The driving behavior analysis module 5 determines the vehicle idling / starting event and the time from module power-on to vehicle starting, the event of excessively long idle time at parking, the event of coasting in neutral, the rapid acceleration / deceleration event, parking corresponding driving behavior events such as accelerator pedal events, speeding events, and fatigue driving events, and record the time and location information of each driving behavior event.

[0062] Other modules and parameters are the same as those in Embodiment 1 or Embodiment 2.

[0063] The corresponding analysis of driving behavior by the driving behavior analysis module can be determined according to the actual situation, and different analysis strategies can be different. Based on the parameters of each indicator in the above system, the driving behavior can be analyzed ...

Abstract

The invention provides a vehicle data processing system for analyzing driving behaviors and relates to a vehicle data processing system, to solve the problems and misjudgment is likely to be caused when data processing is not performed on abnormal data in the process of automobile state analysis including driving behavior analysis. The vehicle data processing system includes a CAN data acquisitionmodule for periodically collecting vehicle operation state data, an abnormal data judging module for comparing various data in the operation state data with a corresponding protocol table and sendingvalid values, abnormal values and data missing conditions of the various data in the operation state data to a data processing module, and the data processing module for processing the operation state data according to classification conditions of the operation state data in accordance with the 10 continuous sampling periods as the standard. The vehicle data processing system is used for vehicledata processing.

Description

technical field [0001] The present invention relates to vehicle data processing systems. Background technique [0002] With the rapid development of the automobile industry, the communication signals of the CAN network are becoming more and more complex and diverse. With the increase of signal types, the abnormal data generated by the signal or the data processing due to signal interruption lead to misjudgment and misjudgment. Moreover, whether it is the automotive industry or the traffic research field, the driver's driving behavior has gradually been studied, but most of the current research is based on recording the driver's driving through the camera, and then analyzing the image to obtain the driver's driving behavior. driving behavior, but this analysis method can only obtain the driver's fatigue driving or speeding behavior, and must also rely on cameras or ultrasonic-based detection equipment, etc. Speed ​​detection equipment will also judge it as normal driving spe...
