Problems solved by technology

[0005] For new energy vehicles, especially when the motor drives the vehicle alone, since there is no intake and exhaust system, there is no intake and exhaust noise, and the radiation noise of the motor is much smaller than that of the internal combustion engine, so the external radiation noise of the new energy vehicle is relatively low when driving. Vehicles driven by internal combustion engines should be small, and pedestrians cannot judge whether there is an approaching vehicle based on the radiation noise of new energy vehicles. Only when the vehicle is very close to pedestrians can it be judged that there is a vehicle approaching. When the vehicle is driven by an electric motor, it is necessary to analyze the impact of the prompt sound on pedestrian safety when the vehicle is approaching

no. 1 approach

[0032] figure 1 It is a schematic configuration diagram showing a vehicle approaching sound collection device according to the first embodiment of the present invention.

[0033] The acquisition device of the vehicle approaching prompt sound according to the first embodiment of the present invention is as follows: figure 1 shown. The collection device collects the prompt sound when the vehicle 900 approaches the observer 800 , and includes an exciter 100 , a trigger 200 , a microphone 300 , a vehicle position detection device 400 and a collection front end 500 .

[0034] The exciter 100 is activated and generates a collection start signal when the vehicle 900 passes by. As the exciter 100 , a known exciter can be used, such as any one of an optical trigger, a pressure pulse trigger, and an ultrasonic trigger. As an embodiment, when the exciter 100 is composed of an optical laser, when the vehicle 900 passes by the exciter 100, an excitation signal is generated because the v...

no. 2 approach

[0045] figure 2 It is a schematic configuration diagram showing a vehicle approach sound collection device according to a second embodiment of the present invention. The difference between the collection device of the vehicle approaching sound in the second embodiment and the collection device of the vehicle approaching sound in the first embodiment is that the vehicle position detecting device 400 includes: a vehicle speed measuring device 401 for detecting the vehicle speed; A distance measuring device 402 for detecting the distance between the vehicle and the observer 800 .

[0046] The vehicle speed measuring device 401 and the distance-to-vehicle device 402 can adopt known vehicle speed devices and distance measuring devices. In this way, the front-end acquisition device 500 collects the vehicle speed of the vehicle 900, the distance between the vehicle 900 and the observer 800, and the distance between the vehicle 900 and the observer 800 according to the vehicle posit...

Abstract

The invention provides a vehicle approach prompt tone acquiring device and a vehicle approach prompt tone acquisition method. The vehicle approach prompt tone acquiring device is used for acquiring a prompt tone prompting that a vehicle approaches to a observer and comprises an exciter, a trigger, a microphone, a vehicle position detecting device and an acquiring front end, wherein the exciter is excited when the vehicle passes through to produce an acquisition starting signal, the trigger is triggered by the observer and produces a trigger signal when the observer judges that the vehicle approaches to, the microphone is used for acquiring an acoustic parameter at the position of the observer, the vehicle position detecting device is used for detecting vehicle position information, and the acquiring front end receives and acquires the acquisition starting signal from the exciter, the trigger signal from the trigger, the acoustic parameter from the microphone and the vehicle position information from the vehicle position detecting device. Therefore, by means of the vehicle approach prompt tone acquiring device and the vehicle approach prompt tone acquisition method, the vehicle approach prompt tone can be accurately developed and designed by combining subjective response of the observer and objective parameter synchronous acquisition.

Description

technical field [0001] The present invention relates to a method and a device for collecting a vehicle approaching sound, in particular to a collection device and a collecting method for analyzing the approaching sound of a new energy vehicle while driving. Background technique [0002] For traditional internal combustion engine-driven vehicles, the main radiated noise sources of the vehicle during driving include: intake system, exhaust system, combustion of the engine body, mechanical noise, tire noise, and wind noise generated by friction between the vehicle and the air. [0003] For new energy vehicles, electric motors are often used as the driving source and hybrid types using electric motors and internal combustion engines as driving sources. These vehicles are usually equipped with a power battery that can be charged and discharged repeatedly, and the electric motor is driven by the electric energy stored in the power battery. In addition to the power battery, the mo...
