Equivalent statistical method for number of times of rapid acceleration and rapid deceleration of vehicle

Abstract

The invention discloses an equivalent statistical method for number of times of rapid acceleration and rapid deceleration of a vehicle. According to the method, through vehicle sparse GPS\Beidou dataand vehicle dispatching data, local average value is used instead of an instantaneous state to deal with the vehicle sparse GPS\Beidou data, and threshold parameters are determined by an aggregation degree of the ratio of rapid acceleration and rapid deceleration, and the equivalent rapid acceleration and rapid deceleration states of the vehicle are judged and identified by the threshold value, sothat the equivalent number of times of rapid acceleration and rapid deceleration of the vehicle can be obtained. Only by processing the sparse GPS\Beidou data, the effect of accurately counting the number of times of the rapid acceleration and rapid deceleration of the vehicle can be achieved, realization is convenient, and the cost is low.

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...

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
