Embodiment Construction

[0024] Further description will be given below in conjunction with the accompanying drawings.

[0025] see figure 1 , according to the degree of membership of each characteristic parameter under different curve types, the weight of the characteristic parameter and the weight of the curve, the present invention can obtain the comprehensive degree of membership of the driver's driving operation mode, which can be used as a comprehensive evaluation index for each driver, so as to evaluate the driver's The operation modes are classified, which specifically include the following steps:

[0026] Step 1: Use the seven parameters of steering wheel angle, steering wheel angular velocity, vehicle speed, pedal opening, vehicle lateral position, turn signal status and surrounding vehicle relationship as the characterization parameters of the driver’s driving operation mode under the curve, which are respectively denoted as P 1 ,P 2 ,P 3 …P 7 , which is used to quantitatively judge the...

Abstract

The invention discloses a driver curve operation mode classification method. Through carrying out a real vehicle experiment, seven parameters of a steering wheel rotating angle, a steering wheel steering angular velocity, a vehicle speed, a pedal opening degree, a vehicle transverse position, a steering lamp state and a surrounding vehicle relationship are selected as characterization indexes fordiscussing a curve driving operation mode; the membership degree of the parameters is determined by adopting a trapezoidal distribution function, the weight of each parameter is determined by utilizing an analytic hierarchy process, and a curve driving operation mode classification model is established, so that a certain theoretical basis is provided for curve safe driving. According to the drivercurve operation mode classification method, the operation behavior of the driver under the curve is explored, the driving operation mode classification model is built, and a certain reference basis is provided for standardizing the operation behavior of the driver and safe driving of the curve. The method is simple and rapid, and is suitable for evaluating drivers under various working conditions.

Description

technical field [0001] The invention belongs to the field of assisted driving, and in particular relates to a method for classifying a driver's curve operation mode. Background technique [0002] Scholars at home and abroad have found that the driving operation mode is mainly related to factors such as gender, age, driving experience and driving experience. Women scored higher on the cautious metric, while men scored higher on the aggressive metric. Women's driving mode is more cautious, and the incidence of traffic accidents is lower. The risky driving behavior of young drivers with a driver's license within one year is affected by gender, sensation seeking, and parental driving behavior. The longer the driver's driving experience and the older he is, the easier he is to perceive the dangers around the driving environment. Drivers with rich driving experience have a more cautious driving style and drive safer. Elderly drivers experience less acceleration and take longer...
