虽然电动汽车为环保驾驶带来了明显好处，但不可否认的是，在学校前方、人行横道或红绿灯处，电动车低速行驶时的声音也很难被听到。汽车工业的明确职责是确保交通安全，保护人员（特别是那些视力受损或依赖听力的人）的安全，因此汽车工业需要尽可能积极地满足国际要求，为电动汽车提供车辆声学警示系统。 车辆声学警示系统（AVAS）的设计目的是发出车辆警报声音，并提醒行人注意电动车辆的存在。这些车辆包括低速行驶（特别是在最低速度范围内行驶时）的混动（HEV）汽车、插电式混动汽车（PHEV）和全电池驱动的电动汽车（BEV），超出该速度范围后，轮胎滚动产生的噪音很容易被听到。意法半导体为您的车辆声学警示系统（AVAS）提供最佳解决方案，包含其汽车用D类音频功率放大器、嵌入式诊断和扬声器电流监测器、电源管理系统IC（包括CAN和LIN接口），还有ASIL-B 32位MCU（配有用于声音生成的固件）。 Read more
