Core Viewpoint - The new national standard for passenger car braking systems (GB21670-2025) has been approved and will take effect on January 1, 2026, marking the first major update since 2008. It aims to regulate the single-pedal driving mode and enhance safety in the automotive industry [1][2]. Summary by Sections New National Standard Implementation - The new standard specifies that the default factory setting for vehicles cannot be the single-pedal mode, although users can manually switch to it. This aims to ensure safety while allowing innovation in technology [2][3]. Safety and User Guidance - The standard requires that if a regenerative braking system has multiple operating states, it must revert to a default state upon powering on, with a maximum deceleration of 3 m/s². Manufacturers must inform users about how to set these states [3][4]. Concerns Over Single-Pedal Mode - The single-pedal mode has been controversial due to safety concerns, particularly the risk of drivers confusing the accelerator with the brake pedal in emergencies. This mode is designed to improve vehicle range and comfort but poses risks if not properly understood [4][5]. Technical and Regulatory Implications - The integration of acceleration and deceleration functions into a single pedal increases system complexity, necessitating higher software reliability and safety measures. The new standard aims to standardize these functions across the industry, potentially increasing costs for component suppliers [5][6].
