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

Example

[0031] The first embodiment

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

[0033] The vehicle approaching prompt sound collection device of the first embodiment of the present invention is such as figure 1 Shown. The collection device collects the prompt sound when the vehicle 900 is approaching the observer 800, and it 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 when the vehicle 900 passes by and generates an acquisition start signal. As the exciter 100, a well-known exciter, for example, any one of a light trigger, a pressure pulse trigger, and an ultrasonic trigger can be used. As an embodiment, in the case of using an optical laser to form the exciter 100, when the vehicle 900 passes by the exciter 100, an excita...

[0044] Second embodiment

[0045] figure 2 It is a schematic diagram showing the structure of a vehicle approaching notification sound collection device according to the second embodiment of the present invention. The vehicle approach prompt sound collection device of the second embodiment is different from the vehicle approach prompt sound collection device of the first embodiment in that the vehicle position detection device 400 includes a vehicle speed measuring device 401 for detecting the vehicle speed and 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 vehicle device 402 may adopt well-known vehicle speed devices and distance measuring devices. In this way, the front-end collecting device 500 collects the vehicle speed of the vehicle 900, the distance between the vehicle 900 and the observer 800, and the vehicle 900 traveling to the observer 800 based on th...

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 prompt sound, in particular to a collecting device and a collection method for analyzing the approaching prompt sound of a new energy vehicle when driving. Background technique [0002] For traditional internal combustion engine-driven vehicles, the main sources of noise radiated by 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, a hybrid type that uses an electric motor as a driving source and an electric motor and an internal combustion engine as a driving source are mostly used. These vehicles are usually equipped with a power battery that can be repeatedly charged and discharged. The electric motor is driven by the electric energy stored in the power battery. In addition to the power...
