[0005] As a further technical solution of the present invention, the intelligent driving system message includes vehicle speed, gear, driving mode, local planning, steering information, warning alarm, traffic lights and road environment.

[0006] As a further technical solution of the present invention, the broadcast voice types include in-vehicle voice and out-vehicle voice; the in-vehicle voice prompts are aimed at safety officers, providing information about the status of the automatic driving system, operation prompts and safety warnings, to help drivers better understand and control the operation of the automatic driving system; the out-vehicle voice prompts are mainly used to convey the vehicle's driving intentions and warning information to external vehicles and pedestrians.

[0007] Another object of the present invention is to provide an automatic driving voice broadcast system, the system comprising: The communication module consists of a vehicle-side switch and Ethernet, and is used to transmit messages from the intelligent driving system. The information analysis module is used to perform reasoning analysis on the received intelligent driving system messages to determine whether voice broadcast is required; Speech synthesis engine, used to convert text information into speech information output; Voice broadcast equipment, used to support the adjustment and switching of volume, broadcast speed, and voice packages; The sound / speaker system is responsible for converting the generated voice information into sound wave signals for transmission; Storage system: used to store the data and programs required for the autonomous driving voice reminder method, including the speech synthesis engine and expert knowledge base.

[0008] Compared with the prior art, the beneficial effects of the present invention are as follows: the present invention provides drivers and external traffic participants with more timely and accurate information through real-time in-vehicle and out-vehicle voice prompts, effectively reducing potential risks caused by missing information or misunderstandings, thereby significantly improving driving safety; through clear and unambiguous voice prompts, drivers and external traffic participants can better understand and adapt to the driving intentions of autonomous vehicles, reduce the troubles caused by poor communication or misunderstandings, and optimize the user experience.
