铁路是对地上设备依赖性很强的交通工具,而汽车作为移动体独立性很强,被称为灵活的交通工具。但是,近年来铁路开始采用蓄电池车辆,同时装用列车安全行车装置。而汽车领域也出现了电动汽车并装用导航设备等。汽车技术与铁路技术正在相互融合。文章对比了电气化铁道车辆和汽车的技术特点,对未来的电气化铁道车辆在电力供给和运行安全方面的技术进行了探索。 Railways are vehicles that are highly dependent on ground equipment. Vehicles are highly independent as mobile and are called flexible vehicles. However, in recent years, the railway has started to adopt battery vehicles and equipped with train safety driving devices. In the field of automobiles, electric vehicles have been installed and navigation equipment installed. Automotive technology and railway technology are merging. This paper compares the technical features of electrified railway vehicles and automobiles and explores the future technology of electric railway vehicles in terms of power supply and operation safety.
