Problems solved by technology

However, electric vehicles do not have an engine, and because the noise of the motor is small, pedestrians cannot be reminded in time during driving, which may easily cause traffic accidents.
[0003] At present, although there are many related technical patents related to the warning sound of electric vehicles, there is no specific limitation on how to analyze the sound factor technology, and the current technology is not perfect in terms of how to correctly issue voice prompts and control the volume of voice output , so it is necessary to improve

Abstract

The invention discloses a voice warning system of an electric automobile. The voice warning system of the electric automobile comprises a sound factor fuzzy analysis device, a digital-to-analogue conversion device, a signal amplification device and a voice warning device. The sound factor fuzzy analysis device is used for acquiring a first fuzzy variable according to a vehicle speed signal and a second fuzzy variable according to an accelerator pedal opening signal, acquiring a third fuzzy variable according to the first fuzzy variable, the second fuzzy variable and a preset fuzzy control rule, and calling a first subordinating degree function corresponding to the first fuzzy variable, a second subordinating degree function corresponding to the second fuzzy variable and a third subordinating degree function corresponding to the third fuzzy variable to output sound factors. The digital-to-analogue conversion device is used for converting digital signals corresponding to the sound factors to be analogue signals. The signal amplification device is used for amplifying the analogue signals. The voice warning device is used for emitting voice warning information according to the amplified analogue signals. The voice warning system can correctly output voice warnings and guarantee the safety of pedestrians. The invention further discloses a voice warning method of the electric automobile and the electric automobile.

Description

technical field [0001] The invention relates to the technical field of electric vehicles, in particular to a voice warning system for an electric vehicle, a voice warning method for an electric vehicle and an electric vehicle with the voice warning system. Background technique [0002] Although traditional fuel vehicles are equipped with engines, although they will produce a certain amount of noise, they will remind pedestrians in time. However, electric vehicles do not have an engine, and because the noise of the motor is small, pedestrians cannot be reminded in time during driving, which may easily cause traffic accidents. [0003] At present, although there are many related technical patents related to the warning sound of electric vehicles, there is no specific limitation on how to analyze the sound factor technology, and the current technology is not perfect in terms of how to correctly issue voice prompts and control the size of voice output , so it needs to be improv...
