Electric vehicle having full-automatic repair function and providing double-frequency loudspeaker voice

Abstract

An electric vehicle having a full-automatic repair function and providing double-frequency loudspeaker voice comprises an electric vehicle body, a controller and a voice loudspeaker device. when circuit faults of the electric vehicle running at low speed in a safety mode, except a speed regulating turning handle fault, occur, a single chip microcomputer circuit of a controller circuit automatically detects the types of the faults, a method set in a program is adopted to temporarily and automatically repair the faults and enable the controller circuit to be in a low-speed running state, the running speed is started and controlled through a speed regulating turning handle, meanwhile the voice loudspeaker device prompts that the types of the faults are temporarily and automatically repaired and the electric vehicle runs at low speed. When a loudspeaker press key is pressed, two types of melodious loudspeaker sounds different in frequency produced by an irony loudspeaker and the loudspeaker can be simultaneously given.

Description

technical field [0001] The invention relates to the field of electric vehicles, including the fields of simple electric vehicles, luxury electric vehicles, mopeds, electric motorcycles, and electric tricycles; more specifically, the improvement relates to a fully automatic repair function and dual-frequency An electric car with a horn sound. Background technique [0002] At present, there are three types of the latest and most advanced similar products on the market that can automatically detect faults and temporarily repair them: one is an electric vehicle that can automatically detect faults and repair faults with one key, including the controller and its voice speaker device, voice speaker device It can be a voice speaker, or an anti-theft device with a voice speaker function; when the electric vehicle circuit has a fault that can be temporarily repaired, the controller immediately stops outputting drive power to the motor and stops.

[0002] At present, there are three types of the latest and most advanced similar products on the market that can automatically detect faults and temporarily repair them: one is an electric vehicle that can automatically detect faults and repair faults with one key, including the controller and its voice speaker device, voice speaker device It can be a voice speaker, or an anti-theft device with a voice speaker function; when the electric vehicle circuit has a fault that can be temporarily repaired, the controller immediately stops outputting drive power to the motor and stops. At the same time, the controller outputs the terminal through the classification signal Output the serial data signal of the fault category, and then prompt the type of fault and the specific operation method of temporary repair through the voice speaker device. Key repair signal input terminal, send the one-key repair manual operation signal to the single-chip microcomputer in the controller circuit, the single-chip microcomputer controls the drive circuit, and sends low-speed driving power to the motor in safe mode, so that the electric vehicle can be temporarily repaired and start low-speed driving; When the car owner is riding, for the sake of safety, he will focus all his attention on the road conditions, and is always ready to take emergency measures according to different road conditions. However, it is difficult for the car owner to pay special attention to random failures that occur unexpectedly at this time. After hearing and remembering the specific content of the voice prompt, even if you want to listen to the prompt content again, you often don’t know how to operate it. The specific method is to turn off the electric door lock first, and then open the electric door lock, so as to repeat the one-button repair of the voice prompt The operation method, especially on the road with many people and vehicles, is more likely to make people anxious and confused, or older people have a bad memory, or it is difficult to hear the voice prompts clearly when parking in a noisy environment. It will bring a lot of trouble to the car owner, and it is very inconvenient; the parking time on the traffic road is longer, and it may also affect the smooth flow of road traffic.

[0003] The second type is similar to an electric car, without voice prompt function. When there is a fault that can be temporarily repaired, the electric car controller stops outputting drive power and stops. Temporary repair work, and then press and hold the speed gear button switch to drive at a low speed in safe mode; if the owner cannot remember the repair operation method when a line failure occurs, there will still be inconvenience similar to the first product

[0004] The third model is similar to an electric car, and does not have a voice prompt function. When various temporary repairable faults occur, the electric car controller stops outputting drive power and stops. At this time, the owner only needs to press the one-key repair button set on the car, You can drive at low speeds in safe mode

[0005] The above three similar electric vehicles must use the same button switch to repair, start and drive at low speed when all repairable faults occur. About 20 kilometers, the speed is fixed and cannot be adjusted, which is very inconvenient to drive in places with many people and vehicles

[0006] The above three models are similar to electric vehicles. When the horn button is pressed, a single iron horn emits a horn sound of a single frequency. horn sound

[0007] Therefore, the existing electric vehicle controller technology still needs to be improved and developed.
