Mistake-prevention system and method for automobile warning tone device

Abstract

The invention relates to the technical field of automobile warning tone devices, in particular to a mistake-prevention system and method for an automobile warning tone device. The mistake-prevention system comprises a power supply power source, a microcontroller, a digital signal processing unit, a power amplifier and a horn, wherein the power supply power source, the microcontroller, the digitalsignal processing unit, the power amplifier and the horn are connected in sequence; and the microcontroller is independently in communication connection with an automobile CAN (Controller Area Network), the power supply power source, the digital signal processing unit and the power amplifier for monitoring the status signals of the power supply power source, the digital signal processing unit andthe power amplifier, or finishing resetting for the power supply power source, the digital signal processing unit and / or the power amplifier. The invention aims to provide the mistake-prevention system and method for the automobile warning tone device. By use of the technical scheme provided by the invention, the technical problem that an existing electric automobile low-speed warning tone devicecan not be restarted due to faults and emits an unanticipated warning tone is solved.

Description

technical field [0001] The invention relates to the technical field of car prompting sound devices, in particular to an error prevention system and method for the car prompt sound device. [0002] technical background [0003] Electric vehicles, as a means of transportation without pollution emissions, are increasingly recognized by the country and the market. Electric vehicles do not have a fuel engine, and there is no sound when they start and run at low speeds, which will cause passers-by next to the vehicle to easily ignore the approach of the vehicle and cause a collision accident. Then the country also promulgated mandatory standards for such issues, requiring electric vehicles to produce prompting sounds, and low-speed prompting sound generators have also begun to be equipped on electric vehicles. [0004] The low-speed beeping device of electric vehicles is to avoid collision accidents. If the device breaks down and cannot operate, or the device emits unexpected beep...
