一种车载生态驾驶辅助系统设计与实现

Design and Implementation of Vehicle Eco-driving Assistance System

提出了一种车载生态驾驶辅助系统(Eco-DriverAssistance System,EDAS)。系统能够辅助驾驶人员改进其不良驾驶习惯和行为,以达到安全驾驶、减少油耗和尾气排放的目的。在EDAS设计方案中,利用传感器技术和通信技术采集车辆的轮胎气压、速度、加速度等数据,并将数据通过蓝牙芯片BC219159传输到智能手机中。智能手机通过燃油消耗模型评价驾驶行为,例如:平均油耗、加速力度和制动力度等。测试结果表明,系统工作稳定,可以有效改进驾驶习惯,节省燃料。

This study presented an assist the driver to encourage sustained c vehicle hanges Eco-Driver Assistance System （EDAS） that could be used to to driving styles and behaviors which were safer, and reduced fuel consumption and emissions. The designed EDAS measured relevant data such as vehicle tire pressure, speed and acceleration utilizing advanced sensing and communication technologies. This data was sent to smart phone based on Android by BlueCore4-Ext Bluetooth chip. Using fuel consumption model, the smart phone provided detailed assessment of driver behavior effects, for example, average fuel consumption, acceler-ation level and deceleration level. The results show that the system can work well, improve driving styles and fuel economy.
