Embodiment Construction

[0113] In order to enable the system to learn the driver's driving style under various working conditions, it has better performance of the adaptive car-following system and improves the acceptance of specific drivers for the adaptive cruise system. The present invention proposes an adaptive learning cruise control system based on mode-switching driving style learning. The system considers a specific driver's driving style and defines the style as the driver's cruising at a constant speed, acceleration approaching, and steady-state car following in different car-following situations. , the switching strategies among several modes of rapid braking and the car-following characteristics under each strategy. The system consists of multiple sub-modules, which are intelligent perception and signal processing module A, data storage module B, mode switching learning module C, car-following characteristic learning module D and vehicle execution control module E.

Abstract

The invention belongs to the technical field of intelligent auxiliary driving for vehicles and vehicle safety and particularly relates to a learning cruise control system and method used for a drivingstyle and based on mode switching. By means of the system and method, self-adaption cruise control is conducted through mode switching of a special driver style and self-adaption learning for the carfollowing behavior. According to the system and method, the driving style is defined to be switch strategies of a cruise control mode, an acceleration approach mode, a steady-state car following modeand a quick braking mode of a driver under different car following conditions, the driving style of the driver is learned, and the driving characteristic of the driver is further learned through a learning method based on a continuous state under each driving mode. The system is suitable for automatic driving of an L2-level vehicle, the aim is to effectively learn the driving style characteristicof the driver, and the adaptability and acceptability of the specific driver for the self-adaption cruise system under different working conditions are improved.

Description

technical field [0001] The invention belongs to the technical field of automobile intelligent assisted driving and automobile safety, and specifically relates to a driving style learning cruise based on mode switching for adaptive cruise control through mode switching of a specific driver's style and self-adaptive learning of car-following behavior Control systems and methods. Background technique [0002] With the continuous increase of vehicle ownership and the frequent occurrence of traffic accidents, intelligent driving assistance technology has received widespread attention and has become a research hotspot. The vehicle's intelligent driving assistance system (ADAS) can effectively relieve the driver's fatigue and effectively ensure driving safety within its applicable working conditions. Among them, the typical longitudinal intelligent assisted driving system-adaptive cruise control system plays an important role, and various control algorithms are applied to system d...
