Kuaidi Technology reported on July 18 that the Xiaomi SU7 is undoubtedly the most popular model this year.
Many car bloggers use this car to brush around, but serious accidents have occurred as a result.
During the review, the blogger mentioned that the change in braking performance of the Xiaomi SU7 will not be reflected in the brake pedal feel.
In other words, the braking performance cannot be felt by stepping on the brake pedal.
In response to this matter, Xiaomi Automobile officially explained and responded, saying: Once again, I sincerely and sincerely remind everyone that the Xiaomi SU7 is a civilian model and not designed for the track.
The personnel have not been professionally trained and the vehicles have not been modified.
Please do not try to drive on the track.
, Later, Xiaomi Automobile said: Xiaomi SU7 uses the world’s first Bosch DPB+ ESP10 fully decoupled brake system.
There is no mechanical connection between the brake pedal and the braking hydraulic system.
The brake pedal is only a fixed stroke and feedback force.
Operating device.
However, if the performance of the braking system is limited, the vehicle will pop up a prompt on the central control screen to remind the driver to pay attention to driving safety.
, “In fact, the fully decoupled braking system is not the first of Xiaomi’s.
It has been widely used in various models before, including some top-level fuel-performance vehicles.
As the world’s first Bosch DPB+ ESP10 system, its advantages mainly have the following four points: Compared with traditional mechanical vacuum braking systems, the DPB fully decoupled braking system can achieve faster pressure building speed and effectively shorten the braking distance, helping Xiaomi SU7 Max version achieve excellent performance of 33.
3m at 100km/h-0 braking.
The design of DPB and ESP dual voltage-building modules can be redundant to each other.
Combined with kinetic energy recovery, quadruple braking redundancy functions can be realized to minimize the risk of brake failure, and can meet the safety redundancy of L4 level automatic driving, providing future assistance.
Lay the foundation for the upgrade of the driving system.
Under extreme working conditions (such as emergency braking), the DPB fully decoupled braking system will not transmit fluctuations in pedal feedback strength caused by ABS operation or brake master cylinder pressure fluctuations, which can provide the driver with stronger braking confidence and ensure safety.
,DPB fully decoupled braking system can more effectively combine motor kinetic energy recovery and mechanical hydraulic braking.
Even if kinetic energy recovery is turned off during daily driving, when the driver steps on the brake pedal, the vehicle will still use kinetic energy recovery to decelerate, which can effectively improve the vehicle’s cruising range.
“, At the same time, Xiaomi Automobile said: We will further improve and make the safety warnings when the performance of the braking system is limited to be more eye-catching and the prompts will be clearer.
