Intelligent electric bicycle traveling with sound

Abstract

The present invention provides an intelligent type electric bicycle which runs with sound. A speed sensor is connected with a first signal processing circuit. A uniform speed awaking sound signal output by the first signal processing circuit is sent into a sound signal selection circuit; a digital speed signal and an acceleration signal which are output by the first signal processing circuit are sent into a second signal processing circuit. An acceleration awaking signal and a logic quantity signal showing whether the acceleration is provided which are output by the second signal processing circuit are sent into the sound selection circuit. The digital speed signal output by the first signal processing circuit is also sent into a third signal processing circuit. The signal of a changeover switch is input to the third signal processing circuit. A steering awaking signal and a the logic quantity signal showing whether steering or not which are output by the third signal processing circuit are sent into the sound signal selection circuit. The output end of the sound signal selection circuit is connected with a loudhailer, therefore, the electric bicycle running state is used as an input control quantity to be transferred into the sound by a processing unit to be expressed, and attention sound is sent out, which improves the safety of the electric bicycle.

Description

technical field [0001] The invention relates to an electric bicycle, in particular to an intelligent running electric bicycle with sound. Background technique [0002] The advantage of electric bicycles is that they are non-polluting. They only need 1 to 1.2 kilowatt-hours of electricity for 100 kilometers, that is, the electricity cost per kilometer is less than a penny. It is a means of transportation that meets energy conservation and emission reduction. At present, a relatively large industrial chain has been formed in the production of electric vehicles. In 2006, the domestic output was over 10 million vehicles, and now the number of vehicles is nearly tens of millions, and it is still increasing. [0003] The main problem of electric vehicles is safety, which poses a great threat to the safety of pedestrians. It is an exaggeration to say that they are "road killers". This is mainly because the sound of electric vehicles running is very small and the speed is quite fas...
