Initiative sound system for car and initiative sound control method for car

Abstract

The invention provides an initiative sound system for a car and an initiative sound control method for the car. The system comprises a sound simulation system. The sound stimulation system comprises a processor, a first loudspeaker, a second loudspeaker, a memorizer and a speed sensor. The processor is electrically connected with the first loudspeaker, the second loudspeaker, the memorizer and the speed sensor. The first loudspeaker and the second loudspeaker are correspondingly arranged on the inner side and the outer side of a motor vehicle driving bin. A plurality of sound files are stored in the memorizer. Sound generated in car driving is recorded in all the sound files, and characteristics of the sound recorded by the sound files are different. The speed sensor collects the motor vehicle driving speed and sends the motor vehicle driving speed to the processor. The processor selects one sound file from the memorizer to be sent to the first loudspeaker and the second loudspeaker to be played according to the driving speed collected by the speed sensor. By means of the initiative sound system for the car, the safety problem caused by low-speed no sound of the new energy automobile is solved, and the driving concentration and the driving joy of drivers are improved.

Description

technical field [0001] The invention relates to the technical field of automobiles, in particular to an active sound system for automobiles and an active sound control method for automobiles. Background technique [0002] The rapid development of the automobile industry has led to continuous improvement of people's requirements for automobile performance, and the rapid development of new energy smart vehicles has also created new challenges to traditional automobile technology. New energy and intelligent vehicles have also become an inevitable trend in the development of automobiles. However, since new energy vehicles are very quiet at low speeds, and the drive system hardly makes any noise, it is difficult for pedestrians, especially the visually impaired, to feel the presence of the car, which increases safety hazards. The social problems caused by the low noise of new energy vehicles have become increasingly prominent. At the same time, due to the low noise of new energ...

AI Technical Summary

Problems solved by technology

At the same time, due to the low noise of new energy vehicles, those drivers who pursue the roar of the engine lose the driving pleasure of new energy vehicles. More importantly, drivers in a silent environment are prone to driving fatigue, causing unnecessary danger.
