The invention discloses a fatigue early warning system based on tightness of a safety belt, which comprises a fatigue sensing module, a fatigue early warning module and an early warning relieving module, and is characterized in that the fatigue sensing module senses fatigue characteristics of a driver and divides fatigue degrees or judges that the fatigue characteristics disappear according to the fatigue characteristics; the fatigue early warning module performs fatigue early warning according to fatigue degree information transmitted by the fatigue sensing module through repeated tightness movement of the safety belt with different intensities; and the early warning relieving module stops the repeated loosening and tightening movement of the safety belt according to fatigue feature disappearance information transmitted by the fatigue sensing module. A driver is accurately and effectively reminded of the fatigue driving state in the mode that the safety belt with different strengths is repeatedly loosened and tightened, a certain relieving effect is achieved, the accident rate is better reduced, and driving safety is guaranteed.
本发明公开了一种基于安全带松紧的疲劳预警系统,包括疲劳感知模块,疲劳预警模块,解除预警模块,其中:疲劳感知模块对驾驶员的疲劳特征进行感知,根据疲劳特征划分疲劳程度或判定疲劳特征消失;疲劳预警模块根据疲劳感知模块传入的疲劳程度信息通过不同强度的安全带反复松紧运动进行疲劳预警;解除预警模块根据疲劳感知模块传入的疲劳特征消失信息停止安全带反复松紧运动。本发明以安全带不同强度反复松紧的方式精准有效地提醒驾驶员疲劳驾驶状态,并起到一定缓解作用,更好的降低事故发生率,保障驾驶安全。
