Abstract
The invention discloses a series-parallel hybrid electric vehicle operating mode switching method. According to suggestions of the invention, a TMC real-time traffic status receiver and a GPS navigator are arranged in an automobile, and the switching method comprises the following steps: the TMC real-time traffic status receiver acquires instant traffic status information, wherein the instant traffic status information comprises urban road sections, suburban or country road sections and expressway sections; the traffic status information is transmitted to the GPS navigator; the GPS navigator controls an operating mode switching unit, so that the automobile can be switched among various operational modes including a pure electric mode, a pure oil mode and a hybrid mode.
Description
Technical field
The present invention relates to hybrid vehicle system application, particularly to a kind of Series-Parallel HEV Working mode switching method.
Background technology
Along with the development of auto industry, vehicle exhaust bring harm the impact of environment is increasingly severe, especially in the middle of city, the harmful gas of motor vehicle emission be haze primarily form reason. Therefore, in city or the area of heavy industry, the discharge reducing vehicle exhaust is the means of main minimizing municipal pollution. Shown by data, municipal pollution is with serious pollution more than suburb or rural area, pollution can reunite with getting up in city, cannot naturally dissipate at short notice, this is because the greening degree in city is low, and most of wind-force can weaken at urban fringe, result in pollution and get more and more with reuniting.
And in suburb or grass roots, wind-force is big, greening degree is high, population density is low, the capacity of self-regulation of the Nature is strong, Absorption for vehicle exhaust to be better than far away city, so, it is solve city haze best bet at present inevitable motor vehicle exhaust emission to suburb or rural area.
Summary of the invention
In order to overcome at least one problem mentioned in background technology, the present invention proposes a kind of energy consumption that can reduce and reduces the Series-Parallel HEV Working mode switching method of motor vehicle exhaust emission.
To achieve these goals, the invention provides a kind of Series-Parallel HEV Working mode switching method, it is characterised in that described automotive internal TMC real-time road receptor and GPS navigator, said method comprising the steps of:
Described TMC real-time road receptor obtains instant traffic information, and described traffic information includes city road, suburb or section, rural area and fastlink;
Send described traffic information to described GPS navigator;
Described GPS navigator controls Working mode changeover unit, switches the operational mode of described automobile, and described operational mode includes pure power mode, pure oil pattern and mixed model.
Optionally, when described running car is when city road, described automobile is switched to described pure power mode.
Optionally, when described running car is when suburb or section, rural area, described automobile is switched to described pure oil pattern.
Optionally, when described running car is when fastlink, described automobile is switched to described mixed model.
Optionally, to the accumulator charging in described automobile while travelling under described pure oil pattern.
Optionally, before described automobile selects to be switched to described pure power mode, first judge whether the state of charge of the accumulator in automobile meets driving requirements.
The beneficial effect of Series-Parallel HEV Working mode switching method of the present invention: Series-Parallel HEV Working mode switching method of the present invention can solve the problem that vehicle exhaust discharges in a large number in the middle of city, also given full play to the advantage of Series-Parallel HEV, the environmental pollution of incity, city and haze problem have been provided a good solution.
Accompanying drawing explanation
Fig. 1 is the schematic flow sheet of Series-Parallel HEV Working mode switching method of the present invention.
Detailed description of the invention
For making the object, technical solutions and advantages of the present invention clearly, below in conjunction with accompanying drawing, the embodiments of the present invention are explained in detail. But, it will be understood by those skilled in the art that in each embodiment of the present invention, propose many ins and outs in order to make reader be more fully understood that the application. But, even without these ins and outs with based on the many variations of following embodiment and amendment, it is also possible to realize the application each claim technical scheme required for protection.
The present invention solves above-mentioned technical problem, the invention provides a kind of Series-Parallel HEV Working mode switching method, in conjunction with Fig. 1, the present embodiment is described in detail.
GPS real-time road technology is primarily referred to as GPS product at the built-in TMC real-time road receptor of fuselage, as long as being configured with TMC real-time road receptor in car, it is possible to obtain instant traffic information. First, by the selected homeposition of driver and in-position, GPS providing best route, route is divided into city road and section, suburb. When GPS points out running car when city road, automobile is immediately switched to pure power mode, and mainly by motor-driven running car, when GPS points out running car when suburb or section, rural area, automobile switch mode is to pure oily pattern; When automobile needs higher power demand (such as climbing, moment high acceleration) or travels on a highway, automobile switch mode, to mixed model, meets power and energy requirement.
Specific operation process, with reference to Fig. 1, comprises the following steps: step 10: driver starts GPS navigation; Step 11: driver inputs the position of beginning and end; Step 12: by GPS programme path, provides best route, and route can be divided into urban road, rural road, super expressway; Step 13: choose whether to start environment optimization model on GPS panel; If so, step 14 is then proceeded to: determine whether city road; If it is not, then proceed to step 24: continue previous status and travel; The judged result of step 14 is if it has, then proceed to step 15: judge whether power energy meets driving requirements; If can meet, then proceed to step 16: switch to pure power mode, if can not meet, then proceed to step 24: continue previous status and travel; The judged result of step 14 is if it has not, then proceed to step 17: determine whether rural road; If rural road, then proceed to step 18: judge whether power energy meets driving requirements; If can meet, then proceed to step 19: switch to pure oil pattern; If can not meet, then proceed to step 24: continue previous status and travel; If not rural road, then proceed to step 20: determine whether super expressway; If super expressway, then proceed to step 21: judge whether power energy meets driving requirements;If can meet, then proceed to step 22: switch to mixed model; If can not meet, then proceed to step 24: continue previous status and travel; If judging it is not super expressway, then proceed to step 23: exit environment optimization model, then proceed to step 24: keep original state.
At automobile by switching working mode to pure oil pattern, automobile is charged to the accumulator in automobile so that it is state of charge is maintained under a full state, prepares for changing road conditions next time; When running car on a highway time, it is necessary to higher speed and acceleration, or walk hill path and climb, automobile switch mode, to mixed model, provides required high-power and high-energy. Thus can solve the problem that vehicle exhaust discharges in a large number in the middle of city, also give full play to the advantage of Series-Parallel HEV, the environmental pollution of incity, city and haze problem are provided a good solution.
It will be understood by those skilled in the art that the respective embodiments described above are to realize specific embodiments of the invention, and in actual applications, it is possible in the form and details it is done various change, without departing from the spirit and scope of the present invention.
