Embodiment Construction
[0025] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the drawings in the embodiments of the present invention. Apparently, the described embodiments are only some of the embodiments of the present invention, but not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.
[0026] The current ESM (Engine Sound Module) will cause a lot of noise pollution when the vehicle is cruising at low speed; and the amplitude adopts a fixed amplitude, which cannot be changed according to the distance between the vehicle body and people or animals.
[0027] Such as figure 1 As shown, in order to solve the above technical problems, this embodiment provides an engine sound early warning method for an electric vehicle equipped with a panoramic ...

The invention relates to the technical field of vehicle-mounted early warning systems, in particular to an engine sound early warning method and system which is used for an electric vehicle provided with a panoramic auxiliary driving system and an engine sound module. The method comprises the following steps that the panoramic auxiliary driving system acquires the image information around the vehicle and identifies an object in the image information according to the image information; the panoramic auxiliary driving system acquires the distance data between the object and the vehicle in real time; the engine sound module acquires the vehicle speed data and starts to give out the warning sound according to the vehicle speed data; and the engine sound module adjusts the amplitude of the output warning sound according to the distance data. The invention aims at providing the engine sound early warning method and system. By adopting the technical scheme provided by the invention, the technical problems that an existing engine sound module has the noise pollution, and the amplitude of the warning sound cannot be adjusted according to the vehicle environments, are solved.
Description
technical field [0001] The invention relates to the technical field of vehicle early warning systems, in particular to an engine sound early warning method and system thereof. [0002] technical background [0003] In an era when non-renewable fossil fuels are becoming exhausted, electric vehicles emerge as the times require. Quietness is a major advantage of electric vehicles, but at the same time, it is not easy for other passers-by to notice, so potential safety concerns are hidden. [0004] The U.S. National Highway Traffic Safety Administration - NHTSA also stated that it will start installing ESM (Engine Sound Module) artificial noise for electric vehicles and Hybrid vehicles in 2019 to warn pedestrians, cyclists and visually impaired people. [0005] The trigger mechanism of the current ESM (Engine Sound Module) is: the warning sound is triggered at the set speed threshold, that is, as long as the vehicle speed is lower than 30 kilometers, the warning sound will match ...
