Cruising mileage computation control system and method thereof

Abstract

The invention discloses a journey continuation mileage calculation control system and a calculation control method. The calculation control system comprises an MCU microprocessor, a journey continuation mileage digital display, a vehicle speed signal sampling circuit, an instantaneous oil consumption signal sampling circuit and a fuel signal sampling circuit; according to the received instantaneous oil consumption signal and the vehicle speed signal, the MCU microprocessor calculates the average oil consumption, and then calculates the journey continuation mileage according to the average oil consumption and the current residual fuel amount; the digital display is used for displaying the journey continuation mileage; the average oil consumption refers to the amount of fuel consumption per kilometer prior to the refilling; and the residual fuel amount is obtained by deducting the amount of fuel consumption measured according to the instantaneous oil consumption signal from the amount of fuel measured after the refilling. The system and the method disclosed by the invention can enable a user to realize how far the remaining fuel in the oil tank can sustain the journey if the current driving situation remains unchanged. The invention has the characteristics of intelligentization and humanization.

Description

technical field

[0001] The invention belongs to the field of automobiles, and in particular relates to a mileage calculation control system and a calculation control method. Background technique

[0002] At present, the cruising range function of cars on the market basically simply uses the remaining fuel volume and average fuel consumption to calculate the distance that can still be driven. But there is a problem, because the calculation method of its average fuel consumption is the integral of instantaneous fuel consumption and vehicle speed, after driving a certain distance, the average fuel consumption will infinitely approach a fixed value, resulting in that the cruising range cannot be truly and accurately reflected in the current vehicle condition The distance that can be driven under road conditions.

[0003] Such as the patent application number: CN03139937.1, the calculation method of its average fuel consumption is exactly to utilize the fuel consumption in a per...

Embodiment Construction

[0028] The present invention will be specifically described below in conjunction with the accompanying drawings.

[0029] like figure 1 As shown, the mileage control system of the present invention consists of the following parts:

[0030] 1. Vehicle speed signal sampling circuit

[0031] 2. Instantaneous fuel consumption signal sampling circuit

[0032] 3. Fuel signal sampling circuit

[0033] 4. MCU microprocessor

[0034] 5. Digital display of cruising range

[0035] The vehicle speed signal is the frequency signal detected by the vehicle speed sensor, and its form is similar to the sampling circuit of the combination instrument ICM, such as figure 2 , 3 As shown; the instantaneous fuel consumption signal is the pulse number of the engine injector given by the engine control unit ECU by collecting, the signal form and the sampling circuit are as follows Figure 4 , 5 Shown; the fuel signal is the resistance signal of the fuel system detected by the fuel sensor, and...
