Whistle sounding method and vehicle-mounted device

Abstract

Embodiments of the present application provide a whistle sounding method and an in-vehicle device, which relate to the technical field of Internet of Vehicles wireless communication, and can provide a targeted prompting effect to drivers of surrounding vehicles and reduce noise pollution. The specific scheme includes: the first in-vehicle device obtains the current location information of the vehicle where the first in-vehicle device is located; receives a plurality of first V2X messages broadcast by the second in-vehicle devices; compares the current location information with the location information in the first V2X message, N third in-vehicle devices are determined from the plurality of second in-vehicle devices; wherein, the driving direction of the vehicle where the N third in-vehicle devices are located is the same as the driving direction of the vehicle in which the first in-vehicle device is located, and the N third in-vehicle devices are multiple Among the second in-vehicle devices, the N in-vehicle devices closest to the first in-vehicle device, N≥1; in response to the user's whistle operation, send a second V2X message including a whistle-playing prompt to the N third in-vehicle devices .

Description

technical field [0001] The embodiments of the present application relate to the technical field of Internet of Vehicles wireless communication, and in particular, to a whistle sounding method and a vehicle-mounted device. Background technique [0002] With the increase in the number of cars, the noise problem caused by traffic noise is becoming more and more prominent. According to the survey agency, the environmental noise in my country's cities mainly comes from traffic noise, and the noise generated by car horns is the main source of traffic noise. From crowded urban roads to beautiful residential areas, the noise generated by car horns is everywhere, not only endangering your own driving safety, but also endangering the rest and health of others. [0003] The existing vehicle whistling method is: whistling through a high-power horn. Among them, the volume of the whistle of a car is generally around 80 decibels; and the sound exceeding the volume of more than 80 decibel...

Problems solved by technology

In addition, for a car with good sound insulation, it is difficult for the driver in the car to hear the whistle of the surrounding vehicles, and the whistle of the surrounding vehicles cannot remind the driver

[0004] To sum up, the current horning scheme used by vehicles may not be able to remind the drivers of surrounding vehicles, but will cause greater noise damage to the crowd around the horning vehicle
