Can you provide detailed information about the braking system of the Xiaomi SU7 Ultra?
The Xiaomi SU7 Ultra adopts the advanced and highly safe Bosch DPB+ESP10 fully decoupled braking system, enabling "four-fold safety redundancy" for the braking system to comprehensively ensure driving safety:
If the brake pedal fails or gets stuck, you can activate emergency braking by holding down the P gear button, achieving a deceleration of up to 0.8g;
If either the DPB or ESP fails, they serve as backups for each other, ensuring sufficient braking capability;
If both DPB and ESP fail simultaneously, mechanical hydraulic braking backup can still be relied upon. By pressing the brake pedal firmly, effective deceleration can be achieved, meeting the regulatory required braking deceleration;
Finally, if the hydraulic and mechanical braking systems completely fail, the Xiaomi SU7 Ultra can still achieve effective deceleration by holding down the P gear button to activate the energy recovery system, with a maximum deceleration of up to 0.25g.
In addition, to prevent safety hazards caused by overheating of the braking system, the Xiaomi SU7 Ultra is specially equipped with a three-level braking warning function, where:
A Level 1 alert is triggered when the brake disc temperature is too high. The vehicle's infotainment system will notify the driver via text prompt and alarm sound;
A Level 2 alert is triggered when the brake fluid temperature approaches boiling point. The vehicle's infotainment system will issue an alarm via text prompt, warning light, and alarm sound, while significantly limiting the power output of the drive system;
A Level 3 alert is triggered when the remaining thickness of the brake pads is insufficient. The vehicle's infotainment system will issue an alarm via text prompt, warning light, and alarm sound, while significantly limiting the power output of the drive system and restricting the vehicle speed to no more than 60km/h.
Therefore, under the "four-fold redundancy" design and "three-level braking warning" function, combined with the track-version braking system standard across all Xiaomi SU7 Ultra models—which consists of large-size carbon ceramic brake discs, Akebono® front six-piston and rear four-piston fixed calipers, etc.—you can fully trust its reliability and stability.
