Embodiment 1

[0077] A driving style recognition and classification method for an automobile adaptive cruise system, the method includes the following steps:

[0078] Step 1. Car-following experiment data collection:

[0079] Considering that the car adaptive cruise system is mainly used in the scene of car-following, we designed a set of typical car-following experimental conditions for data collection. The follow-up experiment needs to be completed by two vehicles, one is the front leading vehicle, referred to as the front vehicle; the other is the experimental follow-up vehicle, referred to as the experimental vehicle. The experimental car in this embodiment is equipped with ABS system, ESC system and Mobileye camera sensor. The Mobileye camera sensor is used to measure the relative speed of the test car and the front car and the distance information between the test car and the front car. The reference speed of the test car is the speed of the test car and the acceleration of the test ...

Abstract

The invention belongs to the technical field of automobile driver driving style identification, and particularly relates to a driving style identification and classification method for an automobile self-adaptive cruise system. The method comprises the steps of acquiring driver data of the automobile following driving condition; clustering driver data by using SOM and K-means algorithms, identifying the driving style of each driver offline, and training a driving style online classifier by using a driving style identification result to obtain the trained driving style online classifier, so asto perform online identification on the driving styles of different drivers; combining the trained driving style online classifier with an automobile ACC system; online identification of the driving style of the driver can be achieved, the automobile ACC system can be correspondingly adjusted according to the drivers of different driving styles, and therefore the personalized requirements of the different drivers for the different driving styles are met, the comfort and acceptability of the automobile ACC system are improved, and meanwhile the driving experience of the drivers is improved.

Description

technical field [0001] The invention belongs to the technical field of driving style recognition of automobile drivers, and in particular relates to a driving style recognition and classification method used in an automobile adaptive cruise system. Background technique [0002] With the rapid development of automobile intelligence and automation, more and more people pay attention to automobile automatic driving technology, and automobile advanced auxiliary driving system, as the primary stage of automobile automatic driving technology, is also more and more applied in the cars visible in the market . Automotive Adaptive Cruise Control (ACC) system, as an important part of automotive advanced driver assistance systems, can control the vehicle to automatically follow the vehicle in front, which can greatly reduce the driver's driving burden and improve the driver's safety. driving safety. However, the current automotive ACC system basically has only one fixed mode, which ca...
