Why is the emergency obstacle avoidance speed set to 55km/h? What standard is the test based on?
Official answer
This test references the international standard ISO 3888-2 "Moose Test" standard, which can intuitively reflect whether the vehicle can complete hazard avoidance when suddenly encountering an obstacle. In winter, when vehicles are prone to breaking down, pedestrians are prone to falling, and roadsides are prone to snow accumulation, better emergency obstacle avoidance capability can provide better safety.
Compared to the international standard ISO 3888-1, the ISO 3888-2 test standard features shorter lane lengths and narrower lane widths, which better reflects the vehicle's suspension performance and electronic control tuning level.
