Description
Technical field
The invention belongs to the Driving Skills field, relate to a kind of best fuel-economy and drive reminding method.
Background technology
As everyone knows, oil belongs to non-renewable resources, be accompanied by the continuous minimizing of oil resources, oil price rises steadily, the fuel economy of automobile more and more is subjected to the attention of domestic and international automobile vendor, respectively structures such as driving engine, change-speed box have been carried out lightweight and optimal design, purpose reduces automobile fuel consumption exactly.
In reality is driven, the state different according to car load, its economic gear and economic speed section are also different.Different chaufeurs, under the identical condition of other condition, the fuel oil that is consumed has nothing in common with each other.Just same driver also is difficult to the well most economical operation area of identification current state for the car load of load at last.
Summary of the invention
The objective of the invention is when driving, can not correctly adopt optimum drive mode, oil consumption problem of higher, and proposed a kind of reminding method that the optimal fuel economy drive manner can be provided according to the speed of a motor vehicle and running environment according to the speed of a motor vehicle at existing chaufeur.
Purpose of the present invention can realize by following technical proposal: a kind of best fuel-economy is driven reminding method, be used for providing the operating recommendation of best fuel-economy driving to the chaufeur of driving procedure, this reminding method is driven prompt system by an optimal fuel economy and is realized, it is characterized in that this reminding method comprises the steps:
A, detection judge whether vehicle is in the cruising state; If enter step b; Otherwise, then return to detect again and judge;
B, send and carry out the instruction that fuel-economy travels and calculates, and enter step c;
C, carry out the fuel-economy calculating of travelling, calculate and enter steps d after finishing;
D, provide to chaufeur and to carry out the concrete operation method that economy is driven.
Drive in the reminding method at above-mentioned a kind of best fuel-economy, among the described step a, judge that the method whether vehicle is in the cruising state realizes in the retaining time and the speed of a motor vehicle by detection.
Drive in the reminding method at above-mentioned a kind of best fuel-economy, among the described step c, carry out fuel-economy travel calculate before, obtain current stabilizing speed as target vehicle speed.
Drive in the reminding method at above-mentioned a kind of best fuel-economy, among the described step c, the fuel-economy parameters such as the minimum fuel oil consumption characteristic of calculating the best fuel-economy district adopt target vehicle speed and binding engine, driving engine, resistance to motion, engine load of travelling are finished.
Here said cruising state refers to vehicle, and to be in some gears in a period of time constant, and the speed of a motor vehicle is stable, this time, we just can think that the road conditions of vehicle ' are more stable, and interior gear of short time generally can not change and the speed of a motor vehicle can not take place than great fluctuation process.
Drive in the reminding method at above-mentioned a kind of best fuel-economy, described optimal fuel economy driving prompt system comprises cruising detection module, economy driving Tip element and can import target vehicle speed and carry out the control module that fuel-economy travels and calculates, described cruising detection module is used for detecting vehicle and whether is in normal motoring condition, drives Tip element by economy after described control module is calculated and finished and exports best driving mode for the chaufeur reference.
When the cruising detection module detected vehicle and belongs to the cruising state, the speed of a motor vehicle after control module is driven vehicle stabilization was as target vehicle speed, carried out the fuel economy calculating of travelling.During calculating, control module goes out best gear and engine speed according to calculation of parameter such as the minimum fuel oil consumption characteristic curve of the best fuel-economy district of the driving engine of this kind of car, driving engine, resistance to motion (surface resistance, grade resistance, windage), engine loads, finally drive Tip element by economy and recommend 1～2 kind of optimal fuel economy drive manner of chaufeur, the chaufeur laggard line operate that adopts a proposal can realize that best fuel-economy travels.
Drive in the reminding method at above-mentioned a kind of best fuel-economy, described cruising detection module comprises speed of vehicle detector and the time meter that calculates in the retaining time.Time meter can be provided with separately, also can be integrated on the control module.Speed of vehicle detector detects Vehicle Speed, when vehicle is in same gear and the speed of a motor vehicle after a period of stabilisation, can think that vehicle has been in stable the driving, and current vehicle speed is as target vehicle speed.
Drive in the reminding method at above-mentioned a kind of best fuel-economy, it is LCD Panel and/or verbal cue device that described economy is driven Tip element.
Drive in the reminding method at above-mentioned a kind of best fuel-economy, described control module comprises instruction control unit, speed of operation judgement control unit and carries out the computing control unit that fuel-economy travels and calculates, described instruction control unit, speed of operation judge that control unit and computing control unit all are connected on the CAN bus, and above-mentioned cruising detection module and instruction control unit connects.Instruction control unit is judged according to the detection data of cruising detection module, is needed to make computations.After the speed of operation judging unit receives the computations that instruction control unit sends, gather current vehicle speed as target vehicle speed, input to the computing control unit and calculate.
Drive in the reminding method at above-mentioned a kind of best fuel-economy, described economy is driven the prompting control unit and is connected on the CAN bus.
Compared with prior art, this best fuel-economy is driven reminding method and is driven prompt system by this fuel economy, allow chaufeur make the driver behavior of relative optimal fuel economy, and be not only to rely on driving experience and custom, initiatively realize the optimal fuel economy of automobile, reduced oil consumption.Can effectively change the driving habit of chaufeur, avoid making driving engine to be in high oil consumption state for a long time, reach the purpose of saving fuel oil consumption with this.
Description of drawings
Fig. 1 is the schematic diagram that optimal fuel economy is driven prompt system.
Fig. 2 is the flow chart of steps that this best fuel-economy is driven reminding method.
