it home reported on september 23 that xiaomi auto today released the xiaomi su7 answers to netizens’ questions (episode 69), answering some questions about the 1.3.0 version upgrade and questions about the high-performance braking system.

it home attaches the specific content as follows:

01. what intelligent driving functions have been upgraded in version 1.3.0?

version 1.3.0 optimizes the "side road passing" function. after the upgrade, the vehicle has the ability to finely model the surrounding environment and restore the real road conditions as much as possible. the vehicle can properly judge the scale during the game and implement driving behaviors such as cross-line avoidance, lane avoidance, lane avoidance, overtaking and lane changing, ensuring that the detour is more flexible and natural on the basis of safety.

the longitudinal function has been optimized, that is, the speed has been optimized. it can deal with oncoming vehicles, pedestrians, tricycles, and scenarios such as vehicles crossing, parallel, and cutting in, and can decelerate and avoid them more gently and stably.

the speed limit logic at intersections has been optimized to improve traffic efficiency at intersections while ensuring safety.

the lane selection logic in intersection scenarios has been optimized to reduce the frequency of steering wheel swinging and driving into the opposite lane, making intersection passing more humane.

the left and right turns have been optimized, making the trajectory more reasonable and the traffic at intersections smoother.

02. after upgrading to 1.3.0, where can i check the smart driving mileage?

after xiaomi su7 is upgraded to 1.3.0 and xiaomi auto app is updated to the latest version (android 1.6.0 / ios 1.6.2), you can query the "smart driving data" through "xiaomi auto app-my-smart driving zone" to view the multi-dimensional data information including the total smart driving mileage, smart driving driving data, driving function mileage ratio, driving function time ratio, and smart driving parking data of your bound vehicle, and you can generate posters with one click for sharing.

03. why can't city noa be enabled when the total mileage displayed on the app exceeds 1,000 km? how can i get the city noa function?

the smart driving mileage can be checked through the "smart driving data" of the bound vehicle in "xiaomi auto app-my-smart driving zone".

the unlocking status of the city noa function can be checked through the "smart driving academy-navigation assistance global function tutorial". the smart driving mileage displayed there is the safe smart driving mileage of the personal account.

taking into account the situation where multiple drivers share the same car, for safety reasons, the driver's personal xiaomi auto app account must have a safe and intelligent driving mileage of 1,000 km and complete the intelligent driving school before the city navigation assisted driving function can be enabled.

04. how to use the newly updated mechanical parking space? what are the precautions?

compared with ordinary parking spaces, mechanical parking spaces are more difficult to park. the core challenge comes from the fact that the width of the inner slot of the mechanical parking space may be only 2.05 meters, and the adjustment space on one side is only 0.05 meters. the second challenge comes from the i-beam column in front of the parking space. the i-beam column is a fixed support in front of the mechanical parking space. when parking, the distance between the i-beam and the vehicle body is very close. when the rearview mirror is folded, there is only less than 10cm of space for the owner to fine-tune. this means that the accuracy requirements for automatic parking of vehicles have been pushed to a new level.

how to use mechanical parking space:

first, when the vehicle speed is lower than 15km/h, the parking entrance will be displayed on the central control screen. click the smart parking button on the screen to enter the smart parking assistance function. please note that if the vehicle is equipped with an active rear wing, please lower the rear wing before experiencing the function to avoid parking failure due to the rear wing blocking the camera's view.

when the system finds a parking space, the parking space will be highlighted in blue on the parking interface, with a text prompt "if you need to park, please step on the brake first" to avoid slipping or scratching accidents caused by releasing the brake prematurely.

when the driver steps on the brake pedal, clicks or confirms the parking space he wants to park in on the central control screen, and then clicks the start parking button on the central control screen. when the system prompts "parking has started, please pay attention to the safety of the surrounding environment", you can release the brake pedal and steering wheel, and the system will help you park the vehicle in the parking space.

after the vehicle is parked in the parking space, the vehicle automatically shifts into p gear and activates the parking brake. parking is completed. at the same time, the central control screen will remind you that parking is completed and automatically exit the parking interface.

mechanical parking spaces are extremely narrow and difficult to park in. please pay attention to the following matters during use:

before parking the xiaomi su7 pro and xiaomi su7 max vehicles, please pay attention to whether the rear wing is lowered, otherwise the parking will fail because the rear wing blocks the camera's view.

during the parking process, you need to pay close attention to the surrounding obstacles and do not rely on the system function. if there is a potential risk, please take over in time by braking or other means to ensure the safety of the vehicle and avoid collisions with obstacles or scratches between vehicles. obstacles that require your close attention include but are not limited to: small pillars, metal chains, and the edge of the pallet.

after parking in a mechanical parking space, you need to pay attention to the risk of the vehicle slipping on the pallet, and ensure that there is no risk of collision between the front of the vehicle and the top beam after the pallet is raised.

05. what is the specific use of the “energy consumption display classification” updated in 1.3.0?

the 1.3.0 version pushed out recently has added "parking energy consumption" statistics, which allows you to view the parking power consumption data of "this parking" and "after self-charging", that is, it provides all energy consumption analysis when the p gear is engaged, making energy consumption transparent.

we found that electric car users are very concerned about power consumption and have many questions, such as: "why does the car lose power after being parked overnight?", "where does the power go when the car is parked?". for questions like the above, users can now view the "energy consumption items" on the "travel and energy consumption-parking energy consumption" page, including in-car activities, sentry mode, temperature presets, remote car control, car refrigerator, vehicle standby, external discharge and many other common functions.

because it involves the power consumption statistics of all parts of the vehicle, this is a very difficult function to develop. for example, if users frequently wake up the vehicle through the "xiaomi auto app" and check the vehicle status, the power consumption will also be included in the statistics. while viewing the energy consumption display, it will also provide optimization suggestions for energy consumption, bringing users a more practical functional experience.

06. under what circumstances does the "energy recovery enhancement" function introduced by xiaomi hyper os 1.3.0 work?

the "energy recovery enhancement" function can only be manually turned on in "master mode". under daily conditions, the maximum braking deceleration of xiaomi su7 max can reach 0.36g. when this function is turned on, even when emergency braking abs (anti-lock braking system) is triggered, the braking energy recovery system can continue to work and provide 0.2g braking energy recovery deceleration, so that the vehicle can fully utilize the motor to recover braking energy during intense driving conditions, greatly reducing the burden on the braking system, thereby delaying the occurrence of brake thermal decay.

the "energy recovery enhancement" function launched this time, combined with the high-performance brake kit previously launched by xiaomi auto (including low-metal brake pads and high-boiling point brake fluid), has greatly improved the braking resistance to thermal decay under extreme driving of xiaomi su7 after the dual capabilities of software and hardware are added.

07. after the "energy recovery enhanced" function is turned on, will the increased kinetic energy recovery cause the battery to overheat?

no. first of all, the charging power of xiaomi su7 max when the kinetic energy recovery is turned to the maximum is much lower than the peak power during normal charging, and the energy recovery enhancement function is a transient state during braking and will not run continuously for a long time.

08. how effective is the high-performance braking system? how is the braking performance of xiaomi su7 after the upgrade?

the high-performance braking system supports higher operating temperatures, is more resistant to high temperatures, has stronger braking resistance to thermal decay, and can moderately increase braking force and enhance braking feel, making it more suitable for advanced driving experience;

high-performance brake pads use a low-metal formula. compared with the original brake pads' nao (non-asbestos organic) formula, the maximum friction coefficient is increased to 0.45, the optimal operating temperature can reach 400°c, and the resistance to thermal decay is stronger; the high-boiling-point brake fluid has a dry boiling point of up to 320°c through formula adjustment, and is also suitable for more intense non-daily driving conditions;

xiaomi su7 is positioned as a high-performance urban car with extreme performance and driving control, providing an excellent foundation for professional driving. however, any extreme driving is beyond the factory calibration range. if the user decides to replace the high-performance brake system, it is recommended to fully understand the product performance boundaries and master professional driving knowledge before trying intense driving to ensure the safety of both the driver and the vehicle. do not rashly challenge extreme driving conditions when the vehicle is in its original factory state.

09. for daily city driving, will there be any improvement if the original brakes are replaced with a high-performance kit?

the high-performance package is designed for performance enthusiasts with extreme driving needs. it can greatly enhance the vehicle's resistance to thermal degradation under extreme braking conditions. however, under daily operating conditions, it will bring certain noise, dust, and changes in foot feel, which will affect comfort.

xiaomi su7 in daily urban driving conditions, users do not need to upgrade to a high-performance braking system. the original brakes can provide better quietness and braking comfort in daily driving. users can choose according to their own usage scenarios and do not upgrade blindly.

special note: both the high-performance braking hardware package and the upgraded "energy recovery enhancement" software function are only suitable for intense driving scenarios on closed and dry roads.
