A few days ago, Xiaomi Auto released the thirteenth episode of SU7 Q&A from netizens, answering questions that users have paid high attention to, such as whether the steering wheel steering feedback can be adjusted independently, whether the camera in the car can be turned off, and when the super power-saving mode will be triggered. The following is Xiaomi's official reply:
Xiaomi SU7 Pro models can be equipped with an optional electric rear wing, why can't physical buttons be optional?
The Xiaomi SU7 Pro does not come standard with an electric rear wing and air suspension by default, and the initial product design only retains two physical buttons for air conditioning temperature and air volume adjustment in the center console. Recently, we learned that the majority of Xiaomi SU7 Pro users, after the optional electric rear wing, hope to be able to increase the physical buttons to adjust the electric rear wing. After several rounds of discussions and production scheduling verification, the Xiaomi automotive product team has made the following adjustments: Xiaomi SU7 Pro models can be equipped with an optional electric rear wing, which will be equipped with four physical buttons in the center console after the option to support the adjustment of the electric rear wing. This product adjustment will be cashed in after the first deliveries of the Xiaomi SU7 Pro. At the same time, users who order the Xiaomi SU7 Pro version before April 30 will receive a free electric rear wing, which will be equipped with four physical buttons at the time of delivery.
Can I adjust the steering wheel steering feedback autonomously, or can I just follow the driving mode?
In the fixed driving modes of "Comfort", "Sport" and "Sport+", there is a factory-preset steering feel, and it does not support individual adjustment;
In the "M1" and "M2" custom driving mode menus, the driver can flexibly choose the light, medium and heavy steering feel according to their preferences.
Does the Xiaomi SU7 have an in-car camera, and can it be turned off to protect privacy from shooting?
Between the steering wheel and the instrument panel, there is a camera for detecting the driver's status. When the driver is detected to close his eyes, turn his head, yawn, use his mobile phone to make and make calls, and other fatigue or distracted behaviors, the system will remind the driver to pay attention to safe driving through voice broadcast, pop-up window on the central control screen, etc.
The system only makes behavior judgments and reminders locally in the car machine, and the image data will not be recorded or transmitted externally, fully protecting the privacy and security of users.
Of course, if you don't need the driver fatigue/distraction reminder, you can turn it off in the "Settings" - "Driving Preferences" menu on the center display. You can even turn off the camera directly in the permission management of the car machine.
What exactly does the Super Power Saving mode in the settings do, and when will it be triggered?
Super power-saving mode refers to the vehicle to reduce vehicle power consumption and increase more cruising range by turning off intelligent driving assistance functions, turning off or limiting comfort functions such as air conditioning and seat heating, and limiting the maximum speed and vehicle acceleration performance.
When the estimated range of the vehicle is less than 50 km, the center display will pop up the relevant settings pop-up window and instructions, at which time you can choose whether to turn on the super power saving mode, and you can also actively turn the super power saving mode on or off at any time during driving. Please open the settings in the control bar at the bottom of the center control screen, enter the driving preferences > super power saving mode, and click to turn the function on or off.
When Super Power Saver is enabled, the following vehicle functions will be restricted:
- The maximum speed limit is 90 km/h
- The system sets up a separate economic power response to control the smoother torque output
- Limited air conditioning performance (reduced airflow, reduced power)
- Turn off the steering wheel heating function
- Turn off comfort features such as seat heating and seat ventilation
- Turn off the ambient lights
- Turn off the exterior mirror heating and rear windshield heating
- The Smart Driving Assist and Smart Parking Assist functions are turned off
- Turn off entertainment, eco services, and sentry mode
- The 12-volt DC power port on the vehicle is disconnected
- Turn off the electric tail control
- Turn off the smart refrigerator in your car
When the vehicle turns on the super power saving mode through the pop-up window on the center control screen, it will automatically exit the super power saving mode after the estimated charging mileage of the vehicle is greater than 300 kilometers. When the Super Eco mode is turned on, you can press the accelerator pedal deep to increase your speed for a short period of time when overtaking.
What is the effect of the Xiaomi SU7 standard tire pressure bar, which is lower or higher than the standard value?
Xiaomi SU7 has formulated a design tire pressure of 2.9 bar based on comprehensive consideration of driving energy consumption, performance and other needs, and it is recommended that users adjust the tire pressure according to the cold inflation pressure of 2.9 bar on a regular basis (such as one month).
Insufficient or too high tire pressure will also have a certain impact on the vehicle's driving. For example, if the tire pressure is too high, it will reduce the rolling resistance of the tire, improve the carrying capacity and impact resistance of the tire, and in addition, it will also cause the tire to harden as a whole and make the driving feel stronger.
On the contrary, if the tire pressure is too low, the rolling resistance of the tire will be increased, and the bearing capacity and impact resistance of the tire will be weakened.
The Xiaomi SU7 brake pedal is not physically connected to the caliper piston, what is the reason for this design and what are the advantages?
Xiaomi SU7 is equipped with Bosch's world-first DPB+ESP10.0 fully decoupled braking system, which has the following four advantages:
Compared with the traditional mechanical vacuum braking system, the DPB fully decoupled braking system can achieve faster pressure build-up speed, which can effectively shorten the braking distance, and help the Xiaomi SU7 Max version to braking 33.3 meters from 100 km/h to 0.
The design of the DPB and ESP dual pressure building modules can be redundant with each other, and the quadruple braking redundancy function can be realized in combination with kinetic energy recovery, which can eliminate the risk of brake failure to the greatest extent, meet the safety redundancy of L4 level autonomous driving, and lay the foundation for the upgrade of the assisted driving system in the future.
DPB fully decoupled braking systemUnder extreme working conditions (such as emergency braking), the brake pedal will not transmit the pedal feedback force fluctuation caused by ABS work or brake master cylinder pressure fluctuations, which can provide the driver with stronger braking confidence and ensure safety;
The DPB fully decoupled braking system can more effectively combine motor kinetic energy recovery and mechanical hydraulic braking, and even if kinetic energy recovery is turned off in daily driving, the vehicle still preferentially uses kinetic energy recovery to decelerate when the driver presses the brake pedal, which can effectively improve the vehicle's cruising range.
Can the automatic parking process be completely relieved to be operated by the vehicle, and the driver will not pay attention to it at all?
At this stage, intelligent driving is all assisted driving, and when using the intelligent parking assistance APA and valet parking assistance AVP functions, the driver still needs to observe the surrounding environment and take over at any time in case of special circumstances.
Is it possible to set a speed limit for automatic parking and AVP valet parking?
Currently, it is not possible to set the upper speed limit of Smart Parking Assist (APA) and Valet Assist (AVP).
Is there an emergency mechanism inside to open the trunk?
In the event of an emergency, you can mechanically open the trunk from the inside as follows:
- Fold the rear seat backs and enter the trunk
- Remove the decorative cover of the trunk emergency switch
- Toggle the trunk emergency switch counterclockwise and push it outward to open the trunk
Fold the rear seat backs
Remove the emergency switch trim cover
Toggle the panic switch counterclockwise
If the unlocking function of the charging cable fails, how to unplug the cable urgently?
If the user's charging cable has an unlocking fault, you can use the emergency unlocking cable to unlock it, and the operation is as follows:
- First of all, click "Stop charging" in the car and open the trunk
- Use the appropriate tools (also by hand) to remove the trunk service cover and locate the unlock pull switch
- Pull the charging cable to the front of the car to unlock the charging cable and take it out normally
As the first model launched by Xiaomi, the Xiaomi SU7 was officially launched on March 28, with a price range of 215,900-299,900 yuan. According to previous reports, after the first model, Xiaomi SU7, Xiaomi Auto is expected to release its first SUV model by the end of this year. For more news about Xiaomi Auto, we will continue to pay attention to it.
