Vehicle oil wear indication method

Abstract

The invention discloses a method for displaying the vehicle gasoline consumption, which belongs to the technical field of automobiles and comprises the following steps: an engine electronic control unit (ECU) calculates instantaneous gasoline consumption information by sampling information of a sensor and transfers the calculated instantaneous gasoline consumption information to a meter singlechip through a CAN bus of a local area network of a controller, the meter singlechip calculates the received instantaneous gasoline consumption information according to a preset formula to obtain a subtotal gasoline consumption value and a statistical gasoline consumption value, and the meter singlechip stores the calculated subtotal gasoline consumption value and the statistical gasoline consumption value and indicates an LCD to display. With the application of the technical scheme of the invention, the subtotal gasoline consumption value and the statistical gasoline consumption value can be stored and precisely displayed without increasing cost or changing hardware.

Description

technical field [0001] The invention relates to the technical field of automobiles, in particular to a method for displaying fuel consumption of automobiles. Background technique [0002] Refer to the technical solution disclosed by the patent No. 02212750 in the prior art and the patent titled "A Fuel Consumption Meter for Automobiles": the synthetic pulse signal obtained by integrating the engine electronic control unit ECU and the logic circuit is directly transmitted to the fuel consumption meter by wires To control the rotation of the fuel consumption meter, this method has the following defects: [0003] 1) The signal is easily disturbed and the indication accuracy is poor; [0004] 2) It can only display fuel consumption information, but cannot store fuel consumption information; [0005] 3) The design of the fuel consumption meter is complicated, which increases the cost; [0006] 4) It takes up space in the cab, and the fuel consumption meter is not well arranged...
