禁止默认单踏板刹停！新规2026年正式实施，特斯拉：暂未收到调整通知

Core Viewpoint - The new mandatory national standard GB 21670-2025 for passenger car braking systems will be implemented starting January 1, 2026, introducing significant changes to existing regulations [1][3]. Group 1: New Technical Requirements - The new standard adds three main technical requirements: improved specifications for electric transmission braking systems, specific standards for regenerative braking, and enhanced emergency braking signal requirements [3]. - A key practical regulation mandates that when the deceleration from regenerative braking exceeds 1.3 m/s², the brake lights must automatically illuminate and remain on until deceleration ends, addressing hidden deceleration risks in some new energy vehicles [3]. - The new standard requires all passenger cars to be equipped with ABS (Anti-lock Braking System) to enhance stability during emergency braking [3]. Group 2: Single-Pedal Braking Mode - The new regulations include requirements related to "single-pedal braking," stating that vehicles cannot default to stopping by releasing the accelerator pedal; drivers must use the brake pedal to stop [3][4]. - This change may imply a formal regulation against Tesla's "single-pedal mode," which has been a well-known feature in their vehicles [3][4]. - The new standard does not completely ban "single-pedal mode" but prohibits it from being the default factory setting, allowing users to manually enable it [8]. Group 3: Implementation Timeline and Industry Impact - Starting January 1, 2026, new vehicles will no longer have the default single-pedal stop function, instead using "creeping" or "rolling" modes as factory settings [8]. - Vehicles sold before 2025 can continue using the default single-pedal mode until January 1, 2027, after which adjustments will be required [8]. - The implementation of the new standard aims to cultivate safer driving habits and reduce the risk of misoperation in emergencies, while still allowing consumer choice in driving modes [8].
