According to data from Tianyancha, Xiaomi Auto Technology Co., Ltd. has recently unveiled a patent titled "Vehicle Alert Control System, Method, Apparatus, Vehicle, and Storage Medium." This innovative system is structured into three key subsystems: a perception subsystem, a decision - making subsystem, and an adjustment subsystem.

The perception subsystem takes charge of gathering environmental perception data as well as the vehicle's triggering information. It acts like the "eyes" and "ears" of the system, constantly scanning and collecting relevant data from the vehicle's surroundings and its own operational status.

The decision - making subsystem then steps in. Based on the information provided by the perception subsystem, it performs in - depth feature analysis. This analysis helps it accurately identify the specific alert scenario the vehicle is currently in. For example, whether it's in a busy urban street with a lot of pedestrians, a quiet residential area, or a highway with high - speed traffic. After determining the scenario, it generates corresponding alert control instructions. Think of it as the "brain" of the system, making smart decisions based on the input data.

Finally, the adjustment subsystem comes into play. It follows the instructions from the decision - making subsystem to fine - tune the sound effects and volume of the vehicle's alert sound. This ensures that the horn sound is appropriate for the given situation, whether it needs to be louder and more attention - grabbing in a noisy environment or softer and less intrusive in a quiet one. In essence, this patent aims to make vehicle horn sounds more context - aware and user - friendly.
