Problems solved by technology

However, vehicle-mounted ADAS equipment involves too many privacy and information security issues, and is expensive, which is not easy to promote and apply. On the other hand, even simple GPS\Beidou data also has high costs in transmission and processing, and cannot be transmitted. Record GPS\ Beidou data every moment
The number of "rapid acceleration (deceleration)" of the vehicle during driving is one of the important indicators for judging the driving behavior of the vehicle, but the instantaneous acceleration (deceleration) speed cannot be obtained through sparse GPS\Beidou data (5S-10S), which makes Even if there is a threshold value for rapid acceleration (deceleration), there is no instantaneous acceleration that can be compared with the threshold to determine whether it is rapid acceleration (deceleration), resulting in the inability to accurately count the number of rapid acceleration (deceleration) of the vehicle

Embodiment 1

[0019] Such as figure 1 As shown, the equivalent statistical method for the rapid acceleration and deceleration times of the vehicle of the present invention includes the process of processing the satellite positioning data of the vehicle. The satellite positioning data includes GPS data or Beidou satellite data. The processing process Including the following steps:

[0020] Step 1. Based on the vehicle sparse GPS\Beidou data and vehicle scheduling data, the local average acceleration of the vehicle is obtained by calculating the average value of the difference between the speed and time between a certain time point of a vehicle and the records of adjacent time points before and after. record data, i.e.

[0021]

[0022] , where i=1, 2..., n; j=1, 2..., m; m represents the number of vehicle identifications, n represents the number of GPS\Beidou data corresponding to each identification, t i For a given time point, t i+1 is the next time point adjacent to the given time ...

Abstract

An equivalent statistical method for the number of rapid acceleration and deceleration of vehicles, through vehicle sparse GPS\Beidou data and vehicle dispatching data, the equivalent statistical method uses local average values ​​instead of instantaneous states to process sparse GPS\Beidou data, through rapid addition and subtraction ratios The aggregation degree determines the threshold parameter, and judges and identifies the equivalent rapid acceleration and deceleration state of the vehicle through the threshold value, and obtains the equivalent rapid acceleration and deceleration times of the vehicle. This statistical method only processes sparse GPS / Beidou data, which is convenient It can achieve the effect of accurately counting the times of rapid acceleration and deceleration of vehicles, which is convenient and low in cost.

Description

technical field [0001] The invention relates to the field of physics, in particular to a vehicle running monitoring technology, in particular to an equivalent statistical method for rapid acceleration and deceleration times of a vehicle. Background technique [0002] In order to carry out risk assessment and control of vehicle driving behaviors and help traffic safety, there are currently a variety of vehicle operation supervision platforms and vehicle auxiliary driving equipment, which have reduced the incidence of traffic accidents to a certain extent. However, the existing various vehicle supervision application platforms require a large number of supervisors to invest, and the supervision depends on the experience and judgment of the supervisors. Experienced personnel need to be trained for a long time, the quality cannot be completely consistent and the manual processing capacity is limited. To achieve effective comprehensive and meticulous management. Therefore, it is...
