Description
Technical field
The invention belongs to the Driving Skills field, relate to a kind of optimal fuel economical drive prompting 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 subject to the attention of domestic and international automobile vendor, respectively the 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 economics step and economic speed section are also different.Different chaufeurs, under the identical condition of other condition, the fuel oil that consumes is different.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 higher problem according to the speed of a motor vehicle for existing chaufeur, 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.
Purpose of the present invention can realize by following technical proposal: a kind of optimal fuel economical drive prompting method, be used for providing to the chaufeur of driving procedure the operating recommendation of optimal fuel economical drive, 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 normal motoring condition; If enter step b; Otherwise, then return again to detect 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.
In above-mentioned a kind of optimal fuel economical drive prompting method, among the described step a, judge that the method whether vehicle is in normal motoring condition realizes in gear time and the speed of a motor vehicle by detecting.
In above-mentioned a kind of optimal fuel economical drive prompting method, among the described step c, carry out fuel-economy travel calculate before, obtain current stabilizing speed as target vehicle speed.
In above-mentioned a kind of optimal fuel economical drive prompting method, 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 normal motoring condition refers to vehicle to be in some gears within 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 Driving Cycle are more stable, and interior gear of short time generally can not change and the speed of a motor vehicle can not occur than great fluctuation process.
In above-mentioned a kind of optimal fuel economical drive prompting method, described optimal fuel economy driving prompt system comprises the detection module that normally travels, economy driving Tip element and can input target vehicle speed and carry out the control module that fuel-economy travels and calculates, the described detection module that normally travels 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 detection module that normally travels detected vehicle and belongs to normal motoring condition, 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.
In above-mentioned a kind of optimal fuel economical drive prompting method, the described detection module that normally travels comprises speed of vehicle detector and the time meter that calculates in the gear time.Time meter can arrange 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.
In above-mentioned a kind of optimal fuel economical drive prompting method, it is LCD Panel and/or language prompting apparatus that described economy is driven Tip element.
In above-mentioned a kind of optimal fuel economical drive prompting method, 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 the above-mentioned detection module and instruction control unit that normally travels connects.Instruction control unit is judged according to the detection data of the detection module that normally travels, 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.
In above-mentioned a kind of optimal fuel economical drive prompting method, described economy is driven the prompting control unit and is connected on the CAN bus.
Compared with prior art, this optimal fuel economical drive prompting method 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 for a long time high oil consumption state, reach the purpose that capable of saving fuel oil consumes with this.
