Abstract

The invention discloses a system and a method for simulating motor vehicle driving sound. The system comprises a driving module, a microprocessor connected with the driving module, a memory connected with the microprocessor, an audio processing module connected with the microprocessor, an audio driving module connected with the audio processing module, a loudspeaker connected with the audio driving module and a power processing module for converting an external voltage source into a nominal voltage source. The system can simulate the driving sound of a motor vehicle under the same state accurately. According to simulation of the driving sound of motor vehicle, the system can help pedestrians to judge vehicle type, speed and distance of a coming vehicle accurately so as to enable the pedestrians to be ready in advance, and therefore accidents of collision of an electric automobile and a person accidentally can be avoided effectively.

Description

technical field [0001] The invention relates to the technical field of electric vehicles, in particular to a simulation system and method for driving sound of electric vehicles. Background technique [0002] When a traditional motor vehicle is running at different speeds, the size and frequency of the sound of the engine will be different. According to the sound of the motor vehicle, pedestrians can roughly judge the speed, distance and state of the vehicle, which can make pedestrians conscious When there is an incoming car at the back, make preparations in advance to greatly reduce the occurrence of accidents. However, electric vehicles are driven by electric motors. The electric motors use brushless motors with very low noise, and the running sound is very small, which is difficult for pedestrians to detect, so that pedestrians cannot realize that there is a car coming from behind, which is easy to cause accidents. [0003] For the simulation device of motor vehicle drivi...
