A pedestrian target crosses the path of a moving car. A camera locked to the windshield tracks it.

一个行人目标穿过行驶中的汽车的路径。固定在挡风玻璃上的摄像头对其进行跟踪。

The car brakes on its own, or it doesn’t. That single pass-fail moment is one of eight criteria now built into America’s federal car safety ratings. Most vehicles on sale today have never faced them. One electric SUV just did, and cleared them all.

汽车要么自动刹车，要么不自动刹车。这一单一的合格/不合格判定标准，是如今纳入美国联邦汽车安全评级的八项标准之一。目前在售的大多数车辆都从未接受过这些测试。有一款电动SUV刚刚完成了测试，并且全部达标。

How the 8-test gauntlet actually measures a car’s driver-assist brain

8项测试挑战究竟如何衡量汽车的驾驶辅助系统“大脑”

Each evaluation measures actual stopping distance, lane-correction performance, and warning timing in repeatable test conditions, not just the presence of an icon on the dashboard. For years, a car could earn a top safety rating with a blind-spot warning system that was technically present but set so conservatively it barely fired. The new pass-fail framework closes that gap by putting each system through timed, measured scenarios with published thresholds it must hit.

每项评估都在可重复的测试条件下衡量实际制动距离、车道修正性能和预警时机，而不仅仅是查看仪表盘上是否显示图标。多年来，一辆车即便配备的盲点预警系统只是形式上存在，设置却过于保守、几乎不会触发，也仍能获得顶级安全评级。新的合格-不合格框架通过设定定时、可测量的测试场景，并明确各系统必须达到的公开阈值，来弥补这一漏洞。

The federal safety program expanded its previous suite by adding four fresh pass-fail criteria: pedestrian automatic emergency braking, lane keeping assistance, blind spot warning, and blind spot intervention. The four pre-existing criteria are forward collision warning, crash imminent braking, dynamic brake support, and lane departure warning.

联邦安全计划在原有标准体系的基础上新增了四项全新的合格/不合格标准：行人自动紧急制动、车道保持辅助、盲点预警以及盲点干预。原有的四项标准为前方碰撞预警、碰撞即将发生制动、动态制动辅助以及车道偏离预警。

Five of the eight depend on brake-system actuation, so the car’s braking hardware and software must work together, not independently. A system that warns but hesitates to actuate fails. That is a harder bar than almost any previous federal benchmark set for consumer vehicles.

八款中有五款依赖制动系统的执行，因此汽车的制动硬件和软件必须协同工作，而非各自独立。一个只会发出警告却迟迟不执行的系统是失败的。这一标准比以往几乎所有面向民用车辆的联邦基准都要严苛。

What happens on a real test track when a car faces these 8 scenarios

当汽车面临这8种场景时，在真实测试赛道上会发生什么

The test facility is not a simulation. Engineers stage repeatable physical scenarios: a foam pedestrian target crossing at a fixed speed, a lane-departure trigger on a marked road surface, a lead vehicle braking hard from highway speed. No partial credit exists in a pass-fail system, which is what makes the format stricter than the weighted scoring consumers are used to seeing.

该测试设施并非模拟场景。工程师们设置可重复的物理测试情境：一个以固定速度横穿的泡沫行人目标、在标线路面上触发车道偏离、前车从高速状态紧急刹车。在这一通过/不通过的考核体系中，**不存在部分得分**，这也使得该考核形式比消费者习惯的加权评分更为严格。

Blind spot intervention is the most demanding of the four newcomers. The car must not only warn the driver that a vehicle is alongside, but must actively intervene if the driver begins to merge anyway, requiring the lane-keeping and sensing systems to coordinate in real time under pressure.

盲区干预是这四项新功能中要求最高的。汽车不仅必须向驾驶员警示旁边有车辆，还必须在驾驶员执意并线时主动干预，这要求车道保持和传感系统在压力下实时协同工作。

The pedestrian AEB test draws the most public attention because it is the most viscerally legible. Passing it in a verified government scenario is meaningfully different from a manufacturer’s own demonstration video.

行人自动紧急制动测试最受公众关注，因为它的直观性最强。在经过验证的政府场景中通过该测试，与制造商自行发布的演示视频有着本质区别。

The certification that put the first passing vehicle on record

这项认证让首辆通过测试的车辆载入史册

On May 7, NHTSA and the Department of Transportation announced that the 2026 Tesla Model Y is the first vehicle to pass the updated New Car Assessment Program test suite for advanced driver assistance systems. The agency stated that by including ADAS in these new tests, it is encouraging automakers to prioritize innovations that keep families safe on the roads.

5月7日，美国国家公路交通安全管理局与美国运输部宣布，2026款特斯拉Model Y成为首款通过</b>高级驾驶辅助系统新版新车评价规程测试套件的车辆。该机构表示，将驾驶辅助系统纳入这些新测试，是为了鼓励汽车制造商优先研发能让家庭在道路上更安全的创新技术。

The certification applies only to Model Y units built on or after November 12, 2025. Earlier production runs do not qualify. That cutoff is a reminder that a software update tied to a specific build date can be the difference between a passing and a non-passing vehicle, even within the same model year.

该认证仅适用于2025年11月12日及之后生产的Model Y车型。早期生产批次不符合认证条件。这一截止日期提醒我们，即便是同一车型年，与特定生产日期相关的软件更新也可能成为车辆能否通过认证的关键因素。

The new framework grew out of NCAP’s 10-year roadmap, finalized in late 2024. The new evaluations are pass-fail checkmarks and do not affect a vehicle’s overall five-star rating, which remains based on crashworthiness. The two systems sit side by side on the rating page, giving shoppers two distinct lenses.

新框架脱胎于国家公路交通安全管理局（NCAP）于2024年末最终确定的十年路线图。新的评估采用合格/不合格的判定方式，不会影响车辆的整体五星评级，该评级仍以抗撞性为依据。这两套评估体系并列展示在评级页面上，为购车者提供了两种不同的评估视角。

Where the benchmark falls short and what rivals still have to prove

标杆的不足之处以及竞争对手仍需证明的地方

Blind spot warning, lane keeping assistance, and pedestrian AEB are standard or widely available on dozens of vehicles. Being first to pass does not mean the Model Y is the only car with these capabilities. The rest of the industry has simply not yet submitted to the same scrutiny.

盲点预警、车道保持辅助和行人自动紧急制动是数十款车型的标准配置或广泛可选配置。率先通过认证并不意味着 Model Y 是唯一具备这些功能的车型。整个行业只是尚未接受同样的严格审查。

Full NCAP implementation was postponed from model year 2026 to model year 2027 after the Alliance for Automotive Innovation, the industry’s main lobbying group, requested more time. That delay means automakers have breathing room before the tests become an industry-wide expectation.

在汽车行业主要游说团体汽车创新联盟要求更多时间后，新汽车评估程序的全面实施从2026款车型年推迟到了2027款车型年。这一延迟为汽车制造商留出了缓冲空间，直到这些测试成为全行业的普遍要求。

The gap between passing and not being tested can be wide. Shoppers currently have no way to know which side of the line any given vehicle sits on, which is itself an argument for volunteering early.

通过与未接受检测之间的差距可能很大。目前，购物者无法知道任何特定车辆处于队伍的哪一侧，这本身就是提前主动报名的一个理由。

The driver-assist landscape is also expanding fast beyond these eight tests. Most Level 3 systems, where the car rather than the driver is legally responsible for the road in defined conditions, are expected to reach consumers in the coming years. You can see how quickly new hardware reaches buyers in our coverage of a factory that hit 50,000 electric SUVs in nine months.

驾驶辅助系统的版图也在快速拓展，已超出这八项测试的范畴。大多数三级自动驾驶系统（在特定条件下，由车辆而非驾驶员承担道路行驶的法律责任）预计将在未来几年面向消费者推出。你可以通过我们对一家9个月内生产出5万辆电动SUV的工厂的报道，了解新硬件交付给消费者的速度有多快。

What the new test standard means for every car buyer shopping today

新的测试标准对如今每一位购车的消费者意味着什么

For an ordinary shopper, the five-star crash rating on a window sticker tells you how well the steel and airbags protect you after a crash. The new ADAS pass-fail mark tells you how well the electronics try to prevent the crash from happening at all. Those are different questions, and for the first time they carry separate, official, government-verified answers.

对于普通消费者而言，车窗贴纸上的五星碰撞评级会告诉你碰撞后钢材和安全气囊对人的保护效果。全新的高级驾驶辅助系统合格与不合格标识则会告诉你电子设备在多大程度上能尽力避免碰撞发生。这是两个不同的问题，而这也是首次有官方、经政府核验的独立答案来解答它们。

The federal label also gives auto insurers their first uniform benchmark for crash-avoidance technology. A Highway Loss Data Institute study of Mazda vehicles found that the most comprehensive ADAS bundle cut property-damage claims by 39 percent. Insurers have long given discounts for vehicles equipped with AEB, but those discounts were based on the presence of hardware, not verified performance. A certified pass changes that calculation.

联邦标签还为汽车保险公司提供了首个防撞技术统一基准。公路损失数据研究所对马自达车辆的一项研究发现，最全面的高级驾驶辅助系统套件使财产损失索赔减少了39%。长期以来，保险公司一直为配备自动紧急制动系统的车辆提供折扣，但这些折扣基于硬件的配备情况，而非经过验证的性能。认证通过则改变了这一计算方式。

NHTSA Administrator Jonathan Morrison called the announcement “a significant step forward” in providing consumers with the most comprehensive safety ratings ever, adding that the Model Y “sets a high bar for the industry.” Hyundai’s record-breaking sales momentum, built partly on strong standard safety scores, is a reminder of how powerfully safety credentials move metal on a lot.

美国国家公路交通安全管理局局长乔纳森·莫里森称该公告是为消费者提供有史以来最全面安全评级方面的“重要一步”，并补充称Model Y“为行业树立了高标准”。现代汽车创纪录的销售势头在一定程度上建立在强劲的标配安全评分之上，这也提醒人们，安全资质对汽车销量有着巨大的推动作用。

The broader question now is how many automakers will voluntarily submit before the 2027 deadline. Those with competitive systems have every incentive to go early. The eight-test benchmark is set to become the next arena where automakers compete for credibility, and right now, only one vehicle has a score to show.

如今更核心的问题是，有多少汽车制造商愿意在2027年的截止日期前主动提交测试结果。那些拥有竞争力测试体系的车企有充分的动力尽早提交。八项测试基准即将成为汽车制造商争夺行业公信力的下一个战场，而目前仅有一款车型公布了测试分数。
