Chinese patent publication number CN200986460; Open day on Dec 5th, 2007; The name of utility model is called the car fuel quantity numeric display unit; This application case discloses a kind of car fuel quantity numeric display unit, and signal receiving and processing device that it is connected by the output terminal that is arranged on liquid level induction pick-up and liquid level induction pick-up in the fuel tank of vehicle and the digital indicator that is connected with the output terminal of signal receiving and processing device constitute.Its weak point is; This device can only show the Fuel Oil Remaining numerical value of fuel tank; Can not display automobile hundred kilometers fuel consumption and the actual fuel consume total amount of automobile, can not help the driver to judge that current drive manner is whether fuel-efficient and whether have leakage with fuel system.
The utility model content
The utility model mainly solves the problem that can't judge when the driver drives that current drive manner is whether fuel-efficient; A kind of vehicle fuel consume quantity display apparatus is provided; The fuel consumption that its display automobile is hundred kilometers helps the driver to judge whether current drive manner is fuel-efficient.
When the utility model also solves running car; The driver is difficult to discover the problem whether fuel system exists leakage; A kind of vehicle fuel consume quantity display apparatus is provided; Actual fuel consume total amount of its display automobile and fuel oil in fuel tank reduction help the driver to judge whether fuel system exists leakage.
In order to address the above problem, the utility model adopts following technical scheme to be achieved:
The vehicle fuel consume quantity display apparatus of the utility model; Comprise CPU, engine electronic control unit, display unit and CS; Said CPU links to each other with engine electronic control unit, display unit and CS respectively, and said display unit and CS are installed on the vehicle console.
In the present technique scheme, the driver is through CS opening automobile fuel consume quantity display apparatus, and engine electronic control unit sends to CPU with the fuel injection pulse width data of the each injection time length of Control of Automobile fuel injector.CPU is according to each fuel injection pulse width and fuel injector structure parameter; Calculate the each accurate distributive value of automobile fuel injector; And calculate the distributive value of unit interval according to each distributive value and fuel injection pulse width; Combine the velograph of current automobile to calculate fuel consumption of 100km at last, on display unit, show.Simultaneously, CPU adds up the distributive value of each fuel injector, obtains actual fuel consume total amount, and on display unit, shows.The driver can judge whether current drive manner is fuel-efficient through the automobile fuel consumption of 100km that display unit shows; The amount of fuel of the minimizing that shows on actual fuel consume total amount that shows through display unit and the vehicle fuel table judges whether fuel system exists leakage.
As preferably, said vehicle fuel consume quantity display apparatus also comprises reset key, and said reset key is installed on the vehicle console, and links to each other with CPU.The driver can carry out clear operation to data presented on the display unit through reset key.
As preferably, said vehicle fuel consume quantity display apparatus also comprises fuel level sensor, and said fuel level sensor is installed in the fuel tank of vehicle, and links to each other with CPU.Fuel level sensor converts the elevation information of fuel tank of vehicle intermediate fuel oil to electric signal and sends to CPU; CPU combines the structural parameters of fuel tank of vehicle to calculate the reduction of the amount of fuel in the fuel tank of vehicle, and on display unit, shows.
As preferably, said vehicle fuel consume quantity display apparatus also comprises audio alert chip and loudspeaker, and said audio alert chip links to each other with loudspeaker with CPU respectively.CPU is calculated the difference of actual fuel consume total amount of automobile and fuel oil in fuel tank reduction; When difference surpasses tolerance value; CPU is sent alerting signal to the audio alert chip, and loudspeaker sends chimes of doom, reminds driver's fuel system to occur leaking.
The beneficial effect of the utility model is: the automobile fuel consumption of 100km that (1) shows through display unit helps the driver to judge whether current drive manner is fuel-efficient.(2) the actual fuel consume total amount of automobile and the fuel oil in fuel tank reduction that show through display unit help the driver to judge whether fuel system exists leakage.
Description of drawings
Fig. 1 is that a kind of circuit theory of the utility model connects block diagram.
Among the figure: 1, CPU, 2, engine electronic control unit, 3, display unit, 4, CS, 5, reset key, 6, fuel level sensor, 7, the audio alert chip, 8, loudspeaker.
Embodiment
Pass through embodiment below, and combine accompanying drawing, do further bright specifically the technical scheme of the utility model.
Embodiment: the vehicle fuel consume quantity display apparatus of present embodiment; As shown in Figure 1; Comprise CPU 1, engine electronic control unit 2, display unit 3, fuel level sensor 6, reset key 5, audio alert chip 7, loudspeaker 8 and CS 4; CPU 1 links to each other with engine electronic control unit 2, display unit 3, fuel level sensor 6, reset key 5 and CS 4 respectively; Audio alert chip 7 links to each other with loudspeaker 8 with CPU 1 respectively, and display unit 3, reset key 5 and CS 4 are installed on the vehicle console, and fuel level sensor 6 is installed in the fuel tank of vehicle.
