小米汽车官方回应赛道测YU7刹车片起火:正常现象!制动不会失效_我的网站

[ 资讯] 日前,小米汽车官方就“在赛道测试小米YU7(参数|询价)时刹车片起火”做出回应。小米汽车官方表示,在赛道驾驶车辆往往需要频繁在超高速行驶中紧急制动,制动盘温度会急剧上升,若未采取有效散热,将引发材料起火。 Simferopol, Oct 19 (UNI) Russia's air defense system shot down Ukrainian drones in the sky over Crimea, as well as over the peninsula's largest city, Sevastopol, on Wednesday, Oleg Kryuchkov, an aide to the Crimean regional head, said.
"[Ukrainian] UAVs [unmanned aerial vehicles] were again shot down in Crimea and Sevastopol. The air defense system went off. The sky over the peninsula is under protection," Kryuchkov said on Telegram.
Earlier in the day, Sevastopol Governor Mikhail Razvozhaev said that Russia's air defense had shot down a Ukrainian drone near a military airfield located in the village of Belbek. Part of its debris fell on a residential building in the private sector. No one was injured.
On February 24, Russian began its military operation in Ukraine responding to calls for help from the Donetsk and Luhansk people's republics. Kiev, in response, launched a series of attacks against Russia. Those included an explosion on the Crimean bridge, terrorist attacks against the Kursk nuclear power plant and attempted sabotage on the TurkStream gas pipeline, according to Russian President Vladimir Putin.

此外,测试车辆未使用小米YU7 Max大师模式中的“能量回收增强”功能。该功能会增强赛道工况下的能量回收强度,降低机械制动系统的负荷,即便出现ABS抱死情况,依然可以提供最大0.2G的制动能量回收,有效减少制动系统温度超过600℃的极端情况发生。在赛道驾驶时,车辆往往需要频繁在超高速行驶中紧急制动,此时制动系统承受的负荷将远高于日常驾驶。在这种工况下,制动盘温度会急剧上升,若未采取有效散热,将引发材料起火。同时,小米YU7作为中大型SUV,相比尺寸更小的SUV车重更高,同时高动力带来的赛道尾速更快,制动系统在猛烈制动过程中产热也会更加明显。

小米YU7 Max采用低金属制动片,材料包含金属纤维、磨料、树脂等有机物。树脂及其他有机物在高温下(一般大于300°C)产生聚合物支链裂解反应产生部分气体,如水分、一氧化碳、二氧化碳、烷基、芳香族气体等,其中部分可燃气体在高温(一般制动盘温度>600?C)及氧气充足的环境下可能会产生短暂明火现象。这属于一种正常的物理现象,但制动性能不会失效。小米YU7定位于城市豪华高性能SUV,我们强烈倡议大家注意驾驶安全,未经过专业升级与整备的原厂车,不要贸然进行赛道尝试。需要在充分了解产品性能边界及专业驾驶知识的前提下,再进行驾驶技能的逐步学习与进阶。若尝试进行专业赛道驾驶,也需要对于车辆的轮胎、制动系统及散热进行必要的升级,并使用大师模式且打开能量回收增强功能,避免在极端工况下出现安全隐患。(编译/ 秦超)
