【太平洋汽车网 评测频道】对于AITO问界这个品牌来说，你我关注都是因为其华为背景。作为手机巨头下场“搞车”的首个正式作品，问界M5被赋予了相当多的概念和元素，这其中智能化是一个主角。例如HarmonyOS智能座舱、麒麟芯片这些东西都是首次出现在量产车上。到底加入华为后，汽车智能化能碰撞出什么样的火花，这次我们就来好好看看。

　　极智+ICT-300智能汽车排行榜出炉，榜单涵盖了62款热门汽车、40个热门品牌，究竟谁才是最强的智能汽车？详情请点击下方图片链接：

　　ICT-300测试项目以及评分标准大家可以在《太平洋汽车＆皆电 [智能汽车] ICT-300评测标准》里查看。

　　先来说说问界M5在本次测试中的成绩吧，问界M5在测试中获得了196分，排在榜单中的第14位。作为造车的后来者，问界M5有这样的成绩算是很不错了。

　　智能驾驶/智能座舱/性能测试三大子版块获得的分数为80/89/27，在这三个版块中，问界M5智能座舱的表现是最出色的，性能测试也排在前部，而智能驾驶方面问界M5表现较为普通，没有超越新势力。可以说问界M5这个成绩主要是靠智能座舱这部分支撑的，这点跟问界M5主打的HarmonyOS智能座舱有密不可分的关系。

　　在智能驾驶部分，问界M5拿到了80分，这个成绩并不算出色。问界M5虽然拥有L2级的驾驶辅助功能，自适应巡航、车道保持、自动泊车功能表现都正常，但遗憾的是假人规避三个项目中都挑战失败了。也正是这个情况，让问界M5在这个部分丢失了不少分数。

　　作为一款智能新车，问界M5全系标配L2级的驾驶辅助功能，包括了主动刹车、自适应巡航、车道保持、自动泊车等功能。在传感器方面，问界M5驾驶辅助相关的是1个博世中长距毫米波雷达（位于前杠下中部）、1个单目摄像头（位于前挡风玻璃上部）。而在后部左右两侧还各有一个角毫米波雷达，用于探测后方来车，实现RCTA 后方横穿预警功能。除此以外，4个环视摄像头以及12个超声波雷达可以为环视影像以及自动泊车提供感知。问界M5这套硬件方案属于常见类型，并没有太特别。

　　问界M5官网没有特别说明是否支持整车OTA升级，但座舱这个部分是支持OTA的。在4月12日问界就推送过一次升级，内容涉及主驾座椅迎宾、灯光提示、智慧语音、大屏UI界面、转向灯提示音等功能的优化。

测试条件：测试车以80km/h开启自适应巡航功能，并且将跟车距离设为第二格。然后行驶过程中在前方会遭遇到靶车非紧急加塞，然后靶车再慢慢停车，停车后10秒后再次起步。

测试条件：测试车以80km/h开启自适应巡航以及车道保持功能，然后车辆会通过一段弯道，以此来考验车辆在高速时的车道保持能力。

测试条件：测试车以30km/h的速度开启所有驾驶辅助功能通过，考察车辆遇到桩桶群时会不会有警示或避让动作（特殊地形识别与避让）；测试车以80km/h开启自适应巡航及车道保持等所有驾驶辅助功能，在虚线处打灯，看看车辆能否支持打灯变道功能（打灯变道）。

　　问界M5不支持高阶驾驶辅助功能，所以像桩筒避让、打灯变道等功能，问界M5都是无法完成的，这点也是情理之中。

　　上面三项是对车辆驾驶辅助功能的测试，而作为一辆智能汽车，除了能帮驾驶员“开车”外，还得能帮驾驶员规避可能发生的交通意外。所以接下来我们会对问界M5进行障碍避让测试，也就是会找假人和假车，看看问界M5能不能及时制动避让。

测试条件：将一个小孩假人固定放置在斑马线中部，测试车以50km/h的速度开启自适应巡航及所有的驾驶辅助功能通过，看看测试车能否在假人前及时停下。

测试条件：一个成人假人会以5km/h的时速通过斑马线，然后测试车以40km/h的速度开启自适应巡航及所有的驾驶辅助功能通过，看看测试车能否在假人前及时停下。

测试条件：小孩假人以5km/h的速度横穿斑马线，测试车辆以40km/h开启巡航及所有驾驶辅助功能通过。与移动假人横穿测试不同的是，鬼探头会在斑马线前一侧加入固定的障碍车，这样会在测试车靠近斑马线时形成“鬼探头”的紧急情况。

测试条件：在模拟隧道内放有一个固定靶车模型，测试车辆以50knm/h的速度开启巡航及所有驾驶辅助功能接近，看看最终测试车能否避让靶车。隧道固定靶车这个项目，其实是模拟在日常行驶中，进入隧道时，隧道内突然有停下来车辆的情况。这种情形下，驾驶员因为隧道内外有大的光线反差，很大概率不会及时发现隧道内停下来的车，最终导致追尾事故发生。如果车辆的驾驶辅助系统可以规避到这一类障碍车，那就会给乘员多一道保障。

测试条件：靶车会以20km/h的速度进行比较紧急的加塞动作，而测试车则会以50km/h的速度巡航行驶。

　　问界M5全系都支持自适应巡航、车道保持等常见的驾驶辅助功能，这些功能在开放高速实测中也能正常使用，并没有给我们留下太多特别的印象。为数不多需要提出来的点是当自适应巡航设定速度提上去以后，自适应巡航系统控制车辆加速较慢。

　　其实驾驶辅助涉及到华为这个元素时，更多人或许会想到激光雷达、自动驾驶等玩意，但这些高阶驾驶辅助功能目前在问界品牌上还未出现。反倒是极狐、广汽等厂商与华为在开展合作，使用上了华为的全栈自研高阶驾驶辅助方案，而目前仅有极狐阿尔法S华为HI版一款车进行了交付。

　　测试完智能驾驶，下面就进入了智能座舱的环节。可以说问界M5整个车的精髓就在于智能座舱，因为HarmonyOS智能座舱是含“华为”量最重的部分。

　　成绩方面，问界M5取得了89分。这个分数是目前智能座舱部分最高的得分，不得不说这HarmonyOS效果立竿见影，直接就拔高了问界M5的体验感。问界M5这套座舱无论是屏幕素质、系统功能交互或是语音控制，表现可以说都是360度无死角。

　　车机除了屏幕素质好是第一要素外，其次就是车机的性能，简单来说就是车机本身的软硬件表现，只有足够强大的车机芯片才能造就良好的触控体验，也只有足够人性化的系统才能造就便捷的交互体验。这几点看着很短，但却是绝大部分车机系统所未能达到的，这也导致了大部分用户相信车机无用论，实际上足够好的车机，才能让用户觉得能用，这也是我们做这个部分测试的出发点，不需要太复杂的测试制度，最基本的东西车机系统能够做好已经很不错了。

　　流畅度、易用性和UI设计

　　车机功能丰富度

 

　　仪表功能丰富度

　　车载系统的扩展性

　　虽然HarmonyOS智能座舱还是首次搭载在量产车上，但它的功能丰富度和完善度都不错，就连语音交互这样不算影响交互使用的功能，它也提供了丰富的功能：可见即可说、连续对话等等。这点我是佩服华为团队的效率，他们甚至比一些已经交付一段时间的新势力更好。

　　基础的语音交互语令对问界M5而言没有压力，空调、导航、音乐搜索、车窗控制四个语令都能识别执行成功。

　　面对粤式的普通话，语音系统就犯难了，我们准备的三句语令仅有“导航到外滩”一句成功识别。这个表现也是情理之中的，毕竟没有多少语音搜索后台能支持粤语识别。

　　语义联想环节，问界M5展现出了超预期的表现，不仅普通的温度和导航类语令能识别成功执行，就连最难的跨功能语令“调低温度并打开车窗、调低温度并导航到静安寺”都能成功识别执行。这也是我们ICT-300测试66款车型中，首次将全部跨功能语令都执行成功的车型，就冲这点来看，问界M5的语音系统确实厉害。

　　智能化进阶需求这个部分考验的是车机深度的细节功能设计，比如车辆的远程控制、账户同步、在线更新以及趣味性小功能等等。

　　前面我们已经看到在ICT-300智能汽车评测标准中，问界M5在智能驾驶、智能座舱方面的表现。接下来，将针对车子本身驾控，进行加速、制动、麋鹿、绕桩以及噪音测试，来看看其性能表现又是如何？

　　问界M5采用的是HUAWEI DriveONE 纯电驱增程平台，悬架使用的是前双叉臂后多连杆独立悬架方案，从账目参数来看，问界M5性能也是能打的。实际测试中，加速、隔音是M5的强项，但遗憾的是刹车成绩就没跟上。

　　我们测试的问界M5是四驱版本，使用的是前HW165后HW200双华为电机，电机总功率496Ps、总扭矩675N·m。全力起步后零百的成绩为5.42秒，这与官方宣称的4.4秒成绩有一点差距，不过也足以秒杀同价位燃油车了。而问界M5这个加速曲线也很有意思，在1秒时G值达到顶峰0.8g，随后G值减少，在80km/h后G值维持在0.4g。所以前半段的爆发力要明显强于后半段。

　　全力制动的话，虽然制动全程减速度都在-1g上下浮动，但最终的成绩并不算理想，只有39.77米，这相比5点多秒的加速而言就有点落差。不过这也跟轮胎状态有关系，或许用新一些的轮胎表现会好点。

　　麋鹿测试的目的是测试车辆的避险能力，考验着车辆悬架和动态调校功底。而我们的麋鹿测试当中，采用打开默认电子系统状态（不手动关闭ESP等），尽可能还原日常用车情况。

　　来到车内噪声测试，考验的是车辆的隔音能力。除了测试传统的怠速、60km/h巡航、90km/h巡航和120km/h巡航四种状态下车内噪声值外，还会记录车外的噪声，并与怠速状态下的车内噪声值对比。

　问界M5在我们榜单中取得这个成绩，可以说是靠智能座舱版块拉分的，在智能驾驶以及性能测试问界M5表现相对普通一些，尤其是智能驾驶，问界M5假人AEB主动刹车部分竟然全部规避失败，这点是不太能接受的。总的来看，问界M5在华为“掺和”的部分表现都不错，看了赛力斯与华为联合设计确实能带来一些改变。（图/文：杜庆炜 ）
