Problems solved by technology

[0003] There are many types of existing cars, the type of car, whether it is loaded, automatic transmission, manual transmission, and different road conditions will all affect the acceleration. Therefore, simply calculating the acceleration to judge the driver's driving behavior will lead to large errors and inaccurate results.
Traditional judgment methods cannot adapt to complex road conditions and different models

Embodiment 1

[0041] Such as figure 2 As shown, the present embodiment judges the car driving behavior by the car driving behavior judging device, and the driving behavior judging device includes:

[0042] The acquisition module is used to connect with the OBD interface of the car to collect the driving data of the car, that is, to collect the acceleration a, vehicle speed v, engine speed Ω, accelerator pedal depth L, brake pedal depth K, steering wheel angle;

[0043] The calculation module receives the collected data from the collection module, and performs calculations based on the collected data to obtain comparison data and establish a comparison matrix.

[0044] The judging module is respectively connected with the acquisition module and the calculation module, and is used to receive the real-time status information of the vehicle collected by the acquisition module, compare it with the comparison matrix in the calculation module, and judge the driving behavior.

[0045] The signal...

Embodiment 2

[0105] Compared with Embodiment 1, step 2 of this embodiment also includes calculating the angle θ between the slope surface and the horizontal plane.

[0106] When the automobile 1 stopped or traveled on the horizontal plane 3, the installation plane of the acceleration sensor on the automobile 1 was parallel to the horizontal plane 3 as required, so the installation plane of the acceleration sensor was parallel to the running plane 2 of the automobile 1 on any slope, like this Acceleration actually measured by the sensor Acceleration measured by the sensor and measured acceleration for the vehicle equal, ie

[0107] Such as figure 1 In the shown mechanical analysis of the slope of the automobile 1, the automobile 1 travels on the driving plane 2 whose slope angle with the horizontal plane 3 is θ. Establish a three-dimensional Cartesian coordinate system of the car, where the planes of the x and y axes are parallel to the slope, and the z-axis is perpendicular to the d...

Abstract

The present invention relates to the technical field of automobile driving behavior analysis, in particular to an adaptive driving behavior analysis method and its device. Firstly, the vehicle driving state parameters such as rotational speed, acceleration and vehicle speed are collected, calculated, and the transmission ratio is obtained; the rotational speed is divided into m rotational speed intervals , divide the transmission ratio into n gear intervals, calculate the average value of the transmission ratio and acceleration of each speed interval and gear interval, and obtain the average value of the transmission ratio and the average acceleration, and obtain comparative data; collect real-time driving state parameters of the car and Compare with the comparison data to analyze whether the car is bad driving. The invention continuously collects the driving data of the car, and can fully establish the benchmark for the driver's driving behavior analysis. The more data, the more it can reflect the driver's normal driving behavior, and it can accurately compare the driver's bad driving behavior. It is the standard for judging step-shift vehicles and step-change cars, and the judgment accuracy is high.

Description

technical field [0001] The invention relates to the technical field of automobile driving behavior analysis, in particular to an adaptive driving behavior analysis method and a device thereof. Background technique [0002] In order to accurately determine whether a driver has driving behaviors such as rapid acceleration or deceleration that are not conducive to safety or fuel economy, it is necessary to monitor and manage the driver's driving behavior. Generally, the driving behavior is analyzed by collecting vehicle driving data to analyze the driver's driving skills. According to the collected vehicle driving data to analyze the driver's driving skills, the existing technology provides "a method for remote real-time monitoring of vehicle sudden acceleration or sudden braking using an acceleration sensor", see the publication number: 102107652A, and the publication date is: The Chinese patent of 2011-06-29, this method is to obtain the accurate acceleration value of the veh...
