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 invention relates to the technical field of vehicle driving behavior analysis, in particular to an adaptive driving behavior analysis method and apparatus. Firstly, vehicle driving state parameters including rotational speed, accelerated speed and vehicle speed are acquired and calculated, and a transmission ratio is obtained; the rotational speed is divided into m rotational speed intervals, the transmission ratio is divided into n gear intervals, mean values of the transmission ratio and the acceleration of each rotational speed interval and each gear interval are calculated, a transmission ratio mean value and an accelerated speed mean value are obtained, and comparison data is obtained; and real-time vehicle driving state parameters are acquired and compared with the comparison data, and a vehicle is analyzed whether to be in a bad driving state or not. According to the adaptive driving behavior analysis method and apparatus, vehicle driving data is continuously acquired, a criterion for driving behavior analysis of a driver can be fully established, a normal driving behavior of the driver can be better reflected through more data, a bad driving behavior of the driver can be accurately compared, judgment criterions of a continuously variable transmission vehicle and a step-down variable transmission vehicle are well compatible, and the judgment precision 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...
