广汽埃安联合滴滴推出全球首辆前装量产L4高度自动驾驶车
本报讯 （记者李雯珊）4月23日，广汽埃安新能源汽车股份有限公司（以下简称“广汽埃安”）与北京小桔科技有限公司（以下简称“滴滴”）自动驾驶强强联合，推出全球首款具备全球适应能力的前装量产L4高度自动驾驶车，并在软硬件实力上完成对现有L2-L4级别的全面超越。
在此之前，量产车中即便价值200万元的顶级智能车，搭载的激光雷达数量也就四颗，而这台L4车型足足用了10颗，包括4颗长距雷达与6颗补盲雷达，最远探测范围200米，更是将最近探测距离由行业目前的30厘米升级至10厘米，实现360°无死角覆盖，启动时就算近距离跑来个小猫也能及时预判。同时这台L4车型首搭红外传感器，能够通过温度感知生命体，漆黑的雨夜马路上穿梭的小动物也能精准识别。该L4车型传感器数量总计33个，对潜在的危险布下了天罗地网。
更多的传感器、更复杂的路况需要更强大的算力，广汽埃安L4车型搭载了高达2000TOPS算力的中央大脑，是特斯拉CyberCab的4倍；更有刹车、传感器等八大安全冗余备份，单系统失效也能正常行驶。此外，该车以“1FIT”为目标打造，即运行10亿小时不超过1次故障。
