Xiaomi says it can predict accidents to prevent them!

Under pressure, Xiaomi unveils a system that alerts drivers before their speed becomes dangerous.

Yesterday we introduced a Chinese authorities’ project aimed at regulating the acceleration of electric vehicles. An initiative full of common sense given the risks tied to surprisingly high performance available for the price of a typical family sedan. Today, Xiaomi reinforces that awareness by unveiling a system capable of alerting drivers when their relative speed could cause an accident. Logical given that the manufacturer is under scrutiny from authorities after a series of accidents caused by its SU7 Ultra!

The patent, published on November 14, 2025 under the name “Vehicle Overspeed Alert Method, Device, Vehicle, Storage Medium, and Program Product”, literally “Method and device for vehicle overspeed alert, storage medium and software”, more simply refers to a device that analyzes the vehicle’s environment in real time. Using sensors, the system identifies objects around the car, calculates the relative speed with respect to those objects and triggers a warning if it exceeds a predefined threshold. The objective: to prevent collisions even when the vehicle remains within legal speed limits.

Frameworks applied to the Highway Code

Xiaomi stresses that traditional systems only react to exceeding the legal limit. Yet, in densely populated areas—schools, construction sites, tourist zones—a vehicle can travel much faster than other road users without being penalized by the standard speed limits. The new device thus adapts to the environment: lower thresholds in high-traffic areas, higher ones on motorways.

Alerts can be visual, displayed on the vehicle’s central screen, or audible thanks to text-to-speech. The driver thus receives immediate feedback on their relative speed, reducing the risk of accidents caused by overly harsh acceleration or a lack of awareness of surrounding traffic. An intelligent application of the mathematical frameworks you learned in high school
