冲上热搜!“网约车电车晕车的原因”引热议

晕车的人都懂:世界在旋转,胃部在翻涌,一股冷汗冒出来。 近日, "网约车电车晕车的原因" 的话题冲上热搜,引发网友热议。 评论区不少网友表示:奇怪!为啥坐 油车没事,怎么一上电车就晕车? 科普中国指出,网约车电车容易晕车并非心理作用,而是因为目前广泛使用的新能源电动车确实可能增加 晕车的概率。 那么,究竟为什么乘坐电动汽车更容易引起不适呢? 要理解这一点,我们首先需要弄清楚: 人为什么会晕车?在医学界,晕车叫作"晕动症", 它的核心解释 被称为"感觉冲突论"。简单来说,我们的大脑为了维持平衡,同时接收了三路信号: 当你坐在车里(尤其是在低头玩手机时),以上"三个部门"便会集体给大脑递交信号冲突: 你动了?我 没动!他动了!你别动! 这种不一致的信息会让大脑混乱,进而产生头晕、恶心等晕车症状。 那么 ,为什么有的人乘坐电动汽车更容易晕车呢? "为了省电,电动汽车普遍配备动能回收系统,若使用不当也会成为晕车的'推手',这也是关键诱因之 一。" 松开电门,系统会强行干预减速以回收电能。 这种频繁、突兀且违背大脑惯性预判的"顿挫感",让内耳 前庭处于一种持续的、高频的混乱纠错中。 最后,关于乘坐电动汽车易晕车的问题, ...

"可是我坐油车就不会晕车,这是为什么?" 想要解决问题,先要弄清晕车的医学原理。晕车在医学上被称为晕动症,是由持续或频繁的加速度变化 引发的不适症状,典型表现为头晕、恶心呕吐、胃肠不适,还会伴随冷汗、面色苍白、心悸、体温波动 等自主神经反应。晕动症常出现在乘坐汽车、轮船、飞机等交通工具时,乘车时看手机、看电影,或是 使用VR设备,都会让晕动症更易发作。 人体能感知车辆的速度变化,全靠藏在内耳深处的前庭系统。这个由三对半规管和球囊、椭圆囊两个耳 石器组成的结构,是人体最精密的"加速度传感器":耳石器负责感知前后、左右的直线加速,半规管则 捕捉旋转、晃动的角加速度。日常生活中,我们依靠前庭、视觉和本 ...

Core Viewpoint - The article discusses the increased likelihood of motion sickness in electric vehicle (EV) passengers compared to traditional fuel vehicles, attributing this to the differences in vehicle dynamics and sensory feedback mechanisms [1][4]. Group 1: Causes of Motion Sickness in Electric Vehicles - Motion sickness, or motion sickness, occurs due to conflicting signals between the vestibular system and visual perception, leading to symptoms like dizziness and nausea [1]. - The instantaneous high torque characteristic of electric motors results in rapid changes in vehicle motion, which can overwhelm the vestibular system before the visual system can adjust, exacerbating discomfort [2][3]. - The absence of familiar engine noise in electric vehicles removes a key sensory cue that helps passengers gauge vehicle behavior, further complicating the coordination of sensory information [2][3]. Group 2: Individual Differences in Motion Sickness - Individual susceptibility to motion sickness varies significantly, influenced by factors such as vestibular system sensitivity, age, and physical condition [5]. - Children and the elderly are particularly vulnerable due to the developmental stage of their vestibular systems and the natural decline in function, respectively [5]. Group 3: Mitigation Strategies - Recommendations for reducing motion sickness include acupuncture to lower vestibular sensitivity, medication for prevention, and gradual acclimatization to electric vehicle dynamics [6]. - Technological advancements in electric vehicles could help minimize sensory conflicts by optimizing driving algorithms and implementing adaptive control systems to adjust vehicle behavior based on real-time data [6][7]. - Ongoing research aims to predict and mitigate motion sickness in electric vehicle passengers by analyzing physiological responses and adjusting vehicle systems accordingly [7].
