Vehicle fuel consumption real-time measuring and displaying device

Abstract

The invention provides a vehicle fuel consumption real-time measuring and displaying device. The vehicle fuel consumption real-time measuring and displaying device is characterized by comprising a signal processing module, a fuel consumption real-time displaying module, an alarming module, a control module, a power supply module and a calibration device, wherein the signal processing module is used for preprocessing a fuel jet pulse signal, a speed signal, a throttle percentage signal and the like; the alarming module is used for monitoring driving actions and prompting; the control module uses a single-chip as a core; the power supply module is supplied with power by a vehicle accumulator; and the calibration device is matched with the device. By the calibration device, the vehicle is subjected to simple calibration, a corresponding relationship between the fuel jet pulse width time and the fuel consumption under different working conditions is obtained, and the corresponding relationship is sent to the single-chip in the vehicle fuel consumption real-time measuring and displaying device after arranging the information. The device can monitor and display fuel oil consumption in one hundred kilometers in real time, and monitor the driving actions in the driving process; and the device can alarm and prompt nonstandard driving actions, so that the device is good for improving driving skills of a driver (particular a new driver); and oil-saving driving and safe driving are realized.

Description

technical field [0001] The invention relates to a real-time measurement and display device for fuel consumption of automobiles, in particular to a real-time measurement and display device for fuel consumption of automobiles equipped with electronically controlled fuel injection engines. Background technique [0002] With the rapid increase of car ownership, non-renewable resources such as petroleum (gasoline, diesel) are gradually decreasing, people's awareness of environmental protection is gradually strengthening, and it is imperative for the automobile industry to save energy and reduce emissions. The fuel saving is not only related to the low fuel consumption characteristics of the vehicle itself, but also directly related to the driver's driving behavior and driving skills. At present, a small number of EFI gasoline vehicles are equipped with a real-time fuel consumption display device, through which the driver can know the fuel consumption of the vehicle in real time, ...
