基于CAN总线的汽车语音功能设计实现

Design and Implementation of Automobile Voice Function Based on CAN Bus

汽车智能化网联化的快速发展,使汽车成为了移动智能空间和场景服务的体验终端。车载主机作为智能座舱人机交互的主控制器,集成了越来越多的车载功能。日趋复杂的功能和界面形成了对驾驶员注意力的争夺,而车载语音技术以其独特的优势帮助驾驶员降低对车内设备的操作依赖,增加车辆驾驶安全性。CAN总线技术作为目前应用最广泛的车载通信技术,为汽车语音功能的设计提供信号传输技术。

With the rapid development of intelligence and networking vehicles,the vehicle is becoming an experience terminal of mobile intelligent space and the scenarios based service.As a master controller of intelligent cockpit and HCI(Human-Computer Interaction),more and more functions were integrated on vehicle mainframe,the driver is easily distracted by the increasing complex functions and interface,but the technology of in-vehicle automatic speech recognition can help the driver reduce their dependence on the vehicle-mounted equipment by its special advantage,and it is helpful to increase the safe driving.As one of the most widely used international vehicle communicationtechnologies,CAN-bus technology provides a signal transmission technologyfor the design of speech recognition.
