Problems solved by technology
Shortcomings of the prior art (1) Judgment criteria based on vehicle speed are relatively single
(2) The type of sensor is relatively simple
(3) At low speed, if there are no pedestrians, there will still be an alarm sound, which will cause unnecessary disturbance to the driver. At this time, the function can only be turned off manually

The invention provides an intelligent electric automobile prompt tone system. The system involves a main machine box, a GPS module, an attitude sensor, a microwave radar, an infrared pyroelectric sensor, an ultrasonic ranging sensor, an out-vehicle alarm device and an in-vehicle alarm device, and a main controller in the main machine box is in signal connection with the GPS module, the attitude sensor, the microwave radar, the infrared pyroelectric sensor, the ultrasonic ranging sensor, a control chip of the out-vehicle alarm device and a control chip of the in-vehicle alarm device. According to the intelligent electric automobile prompt tone system, through the arrangement of the plurality of sensors, information from various directions of outside various objects can be received, so that whether an alarm is given or not is judged, the data acquisition is accurate, and the intelligent degree is high.
Description
technical field [0001] The invention belongs to the field of automobile systems, and in particular relates to a prompt sound system for an intelligent electric automobile. Background technique [0002] With the rapid development of China's new energy vehicle industry, more and more new energy vehicles will be put on the market, among which electric vehicles are the most important component of new energy vehicles. The types of electric vehicles include pure electric vehicles, hybrid vehicles, and fuel cell vehicles. Electric vehicles are quieter at low speeds than conventional internal combustion engine vehicles. Studies have shown that when electric vehicles are running at low speeds, the average external noise is about 10dB lower than that of internal combustion engine vehicles, which makes it difficult for other road users, such as pedestrians and bicycles, especially blind and visually impaired people to perceive electric vehicles. The approach of the car leads to a tra...
