Embodiment

[0037] Such as figure 1 As shown, the scene-based driving behavior evaluation method of this embodiment uses the vehicle ECU data acquisition device to read the vehicle operating condition data and vehicle performance data, and synchronizes these data to the cloud intelligence in real time through the wireless network module of the mobile intelligent terminal. platform; the cloud intelligent platform uses big data analysis methods to analyze the same driving itinerary record data as the itinerary, and identify the car performance used for these trips and the driving actions that have occurred; The action recognition results are further analyzed to identify the road network characteristics of the driving route. By accessing external dynamic traffic condition data, the traffic condition data at each moment of the itinerary is obtained, and the traffic condition data at each moment of the itinerary is corrected by using the driving history data on the route to obtain more accurat...

Abstract

The invention discloses a scenario-based driving behavior evaluating method. The method comprises the following steps that: S1, a data acquisition unit for an ECU (Electronic Control Unit) of a vehicle collects the vehicle working condition data and vehicle performance data, and then the collected data is synchronized to an intelligent cloud platform in real time through a wireless network; S2, the intelligent cloud platform analyzes the recorded data for the driving travel same as the travel route by a big data analysis method; and S3, the intelligent cloud platform receives the data transmitted from an intelligent mobile terminal, the data is stored in the platform, and the driving travel of the time is accurately analyzed by a big data analysis method according to the historical travel data. The method is high in accuracy, can accurately evaluate the degree of proper driving actions of a driver in different situations and objectively reflect the driving skill level of the driver, and meanwhile, is high in computational efficiency, and can quickly evaluate the driving behavior of the driver and feedback the evaluation result in time.

Description

technical field [0001] The invention relates to the technical field of automobile road traffic safety, in particular to a scene-based driving behavior evaluation method. Background technique [0002] The existing driving behavior evaluation method uses the vehicle ECU data acquisition device to read the vehicle operating condition data and vehicle performance data, and transmits the vehicle operating condition information to the driving behavior analysis terminal for analysis. The driving behavior analysis terminal stores typical irregularities. The characteristics of driving behavior can be used to identify typical irregular driving behaviors based on these characteristics, and the driving behavior can be evaluated by counting the number of occurrences of irregular driving behaviors and the total fuel consumption of the trip. [0003] Chinese invention patent 201010280297.3 (application publication number is CN102044095A) discloses a personal driving behavior analysis manag...
