Embodiment Construction

[0035] The present invention will be further described below in conjunction with the embodiments shown in the accompanying drawings.

[0036] I. Driving state model establishment

[0037] In order to realize the real-time detection of driver distraction, it is necessary to establish a model of focused driving and distracted driving offline. The generation of distracted driving here is due to the driver performing certain tasks unrelated to driving (such as using a mobile phone, adjusting the radio, setting GPS), consciously or unconsciously diverting attention from the main driving task.

[0038] (1) Data collection

[0039] The present invention utilizes a driving simulator to collect driving data under two conditions of focused driving and distracted driving. On the driving simulator, the driver can use the steering wheel, accelerator pedal and brake pedal to manipulate the virtual vehicle according to the virtual road scene and vehicle motion state displayed by animation....

Abstract

Provided is a lane departure alarming method with a driving distraction state considered. The method comprises the steps that whether a driver is in a distracted driving state at present is judged according to the traveling track of an automobile and the operation information of the driver; distinguished alarming strategies are provided according to the detecting result of distracted driving, and when driving distraction is not detected, the time for lane departure alarming is delayed. A lane departure alarming system for achieving the method comprises an environment sensing unit, an information control unit, a data processing unit, a distraction detecting unit, a road virtual unit and an alarm decision making unit. The yaw angle of the automobile and the rotating speed signal of a steering wheel are acquired from the environment sensing unit and the information control unit, corresponding standard deviation statistical data can be obtained after data processing, and driving distraction detection is conducted. The alarm decision making unit makes alarm decisions, and judges whether the current alarm signal is restrained or not. The lane departure alarming method and system can provide the distraction driver with timely lane departure alarm, and meanwhile avoid frequent false alarm to the focused driver so that disturbing to the driver can be reduced.

Description

technical field [0001] The invention belongs to the technical field of vehicle control, and relates to a vehicle auxiliary driving device, in particular to a vehicle departure warning device. Background technique [0002] For cars driving on the expressway, the driver's inattention caused by making calls, adjusting the radio, etc. will cause the vehicle to deviate from the current driving lane, drive into the adjacent lane or rush out of the road, causing traffic accidents. [0003] In order to avoid traffic accidents caused by Single Vehicle Road Departure (SVRD, Single Vehicle Road Departure), lane departure warning systems are widely used. LDWS obtains the relative pose of the vehicle in the current lane through the perception system, judges whether the vehicle has or is about to deviate from the road according to a specific alarm decision-making algorithm, and warns the driver through the alarm device. [0004] In the human-vehicle-road system, the existing lane departu...
