Why does the Xiaomi Pengcheng come standard with 9 collision sensors across all models?

Official answer

After a collision occurs, whether airbags can deploy timely and accurately depends not only on the airbags themselves, but also heavily on the rapid detection and accurate judgment of the collision.

The Xiaomi Pengcheng is equipped with 9 collision sensors across all models, located at the front crash beam, front longitudinal beams, front doors, B-pillars, and C-pillars, covering multiple key areas from the front of the vehicle to the sides of the passenger compartment.

This design primarily considers that real-world collision locations and directions are highly complex. By placing sensors at different positions on the body, we can more fully acquire collision information, more accurately identify the location and direction of the collision, and provide a basis for the timely and precise deployment of restraint systems such as airbags.

As an intelligent, variable large-space SUV, we have extended side collision sensing to the C-pillar area, allowing for more comprehensive coverage of mid-to-rear side collision scenarios.

The core purpose of the 9 collision sensors is not to pursue quantity, but to achieve more comprehensive collision sensing coverage, providing a more sufficient sensing foundation for passive safety protection for passengers in every row.
