The invention discloses an unreasonable oil consumption real-time alarm method and an OBD vehicle-mounted terminal thereof, and belongs to the technical field of vehicle electronics. Whether the vehicle has unreasonable fuel consumption and fuel consumption reasons in the driving process or not is scientifically judged through real-time data such as the accelerator opening degree, the vehicle speed and the engine rotating speed according to the running principle of the diesel vehicle; and a driver is reminded through voices. The OBD vehicle-mounted terminal comprises a first CAN bus unit, a second CAN bus unit, a single-chip microcomputer including an unreasonable oil consumption real-time alarm program, a storage unit and an alarm prompt unit. And driving parameters are received from theOBD system of the diesel vehicle and transmitted to the single chip microcomputer, whether unreasonable oil consumption exists in the driving process or not is judged in real time, and the oil consumption per hundred kilometers is calculated. Besides, the single-chip microcomputer calls the corresponding voice file from the storage unit and informs the driver of the corresponding voice file through the alarm prompt unit to prompt the driver to change the driving behavior, and unreasonable oil consumption is avoided.

    本发明公开了一种不合理油耗实时报警方法及其OBD车载终端,属于车辆电子技术领域。本发明通过油门开度、车速和发动机转速等实时数据,并根据柴油车运行原理,科学的判断得出车辆在行驶过程中是否具有不合理的油耗及其耗油原因,并通过语音提醒给驾驶员。本发明的OBD车载终端包含第一、第二CAN总线单元、包含不合理油耗实时报警程序在内的单片机、存储单元和报警提示单元。从柴油车OBD系统中接收行车参数并传输至单片机,实时判定行车过程中是否具有不合理油耗,并计算出百公里耗油量。此外,单片机从存储单元中调取相应的语音文件,通过报警提示单元告知驾驶员,提示驾驶员改变驾驶行为,避免不合理油耗。
