As shown in fig. 2, applied to the above apparatus, the driver steps on the accelerator pedal and the wheels are rotated. An angle sensor in the ABS module detects the rotation of the wheel shaft and sends a wheel speed pulse message to a whole vehicle can bus. The VCU or the MCU control unit reads a wheel speed message on the bus, calculates the current vehicle speed and controls the voltage regulator according to a corresponding protocol of the vehicle speed and the sound loudness. The voltage regulator regulates the voltage of the two ends of the electric horn. The electric horn makes a sound to remind users of surrounding roads.
The sound is from 0Km/h to 20Km/h in the acceleration process, and the sound is gradually increased from 0 db; from 20Km/h to 25Km/h, the sound is gradually reduced until it is reduced to 0 db.
The sound is gradually increased from 0db during the deceleration process from 25Km/h (including 25Km/h) to 20 Km/h; from 20Km/h to 0Km/h, the sound is gradually reduced until it is reduced to 0 db.
