  AEC-Q100认证:车规级芯片的“黄金标准”

  AEC-Q100是由国际汽车电子协会制定的集成电路可靠性测试标准,覆盖加速环境应力、寿命仿真、封装完整性等七大测试类别,是汽车芯片进入量产供应链的“入场券”。微传科技的轮速传感器VCW1885系列在极端温度(-40℃至150℃)、电磁干扰及振动等严苛条件下,通过了超过30项EMC测试与三温测试,展现了卓越的稳定性和抗干扰能力。

  微传轮速传感器VCW1885

  VCW1885基于微传科技自主研发的AMR(各向异性磁阻)技术,相比传统霍尔传感器具备显著优势:

  1、磁阻式轮速传感器具有极低的jitter(<0.1%),远低于霍尔式轮速传感器的2~3%,使其在能够精确监测轮速的同时,还具有胎压监测功能。

  2、磁阻式轮速传感器能容忍更大的感应气隙Airgap,最大可达5.5mm左右,在剧烈颠簸的路况下也不易丢失信号,具有优秀的鲁棒性。3、磁阻式轮速传感器相对于霍尔式更易于安装,侧面感应时无需弯折。4、AMR磁阻式轮速传感器高精度、高响应以及优异的防震动、高稳定等性能,在自动泊车辅助功能上有更加明显的性能优势,是汽车自动驾驶的制动系统的安全保障。
