Background technology
Day by day serious along with energy shock and environmental pollution, energy-conservation is the two principal themes of current automobile industry development with environmental protection.From the developing direction of new-energy automobile, pure electric automobile (BladeElectricVehicles, BEV) important developing direction will be become, but at present still there is the restriction of the factors such as the technology of vehicle mounted dynamic battery group and cost in pure electric automobile, makes the slower development of pure electric automobile.Hybrid vehicle (HybridElectricVehicle, HEV) had both inherited the strong point of conventional engines high-energy-density, high-specific-power, compensate for again the deficiency of pure electric automobile, and significantly improved car load fuel-economy performance and emission behavior.Stroke-increasing electric automobile (Range-ExtendedElectricVehicle, REEV) be the plug-in serial type hybrid automobile that the pure motorized motions of a kind of energy travels, electric energy is the main energy sources driving stroke-increasing electric automobile, fuel oil is stand-by power source, the distance increasing unit when vehicle mounted dynamic battery electric energy is not enough is only had just to start working, to electrokinetic cell electric energy supplement, make vehicle can continue to travel arrival destination.Stroke-increasing electric automobile has many advantages, but still there is following shortcoming: travelled distance is known needed for the vehicle, and required travelled distance is in certain short travel, now vehicle adopts pure motorized motions, distance increasing unit will cut little ice, and just exist as a load, which increase the waste of the energy.In order to solve the problem, be integrated in one the fuel tank of stroke-increasing electric automobile, driving engine, electrical generator formation distance increasing unit, and adopt fast assembling disassembling structure by between distance increasing unit and vehicle frame, form reassembling type distance increasing unit, when judging that travelled distance needed for vehicle is short travel, by fast assembling disassembling structure, reassembling type distance increasing unit being disassembled, adopting pure electric motorized vehicle, to reduce load when short travel travels, thus reduce energy energy consumption; When the non-short travel of required travelled distance, by quick attach structure, reassembling type distance increasing unit is installed, adopt extended-range to drive vehicle.
Summary of the invention
When the present invention is directed to stroke-increasing electric automobile short travel traveling, distance increasing unit does not provide power and exists as just load, the problem wasted energy on the contrary, a kind of driving method when stroke-increasing electric automobile short travel travels is proposed, when the short travel travelled needed for chaufeur known vehicle is estimated within the scope of course continuation mileage at vehicle mounted dynamic battery, dismounting distance increasing unit, reduces vehicle load, thus reduces the consumption of energy.
The invention provides a kind of driving method when a kind of stroke-increasing electric automobile short travel travels, its concrete steps are as follows:
The first step, is connected with charging pile by external plug-in charger, is full of by vehicle mounted dynamic battery electricity;
Second step, vehicle mounted dynamic battery control subsystem carries out course continuation mileage expectation to vehicle mounted dynamic battery, and the mileage of expectation is S, and expectation course continuation mileage S is sent to whole-control system;
3rd step, driver's operation global positioning system, selects your destination, and is calculated arrive travelled distance needed for destination by global positioning system, and travelled distance needed for calculating is sent to whole-control system;
4th step, whole-control system is to expectation course continuation mileage and required travelled distance
compare, if when estimating that course continuation mileage is greater than required travelled distance more than 10%, display is used short travel driving method by instrument display system, carries out the 5th step; If when estimating that course continuation mileage is not greater than required travelled distance more than 10%, instrument display system will adopt extended-range driving method, carry out the 7th step;
5th step, by the Quick disassembling structure between reassembling type distance increasing unit and vehicle frame, disassembles reassembling type distance increasing unit, forms the drive system only having pure power driven system;
6th step, after dismounting distance increasing unit, the monitoring of reassembling type distance increasing unit control system is less than distance increasing unit, whole-control system disconnects and the communication of reassembling type distance increasing unit control system, only pure power driven system is controlled, drive the short travel of vehicle to travel by vehicle mounted dynamic battery control subsystem and motor control subsystem to vehicle mounted dynamic battery and motor control;
7th step, when after the 4th step, instrument display system display adopts extended-range driving method, and reassembling type distance increasing unit is disassembled, now needs the reassembling type distance increasing unit that disassembles by the quick attach structure Fast Installation between itself and vehicle frame; If reassembling type distance increasing unit is not dismantled directly can start traveling.
Beneficial effect: the present invention is when the short travel travelled needed for stroke-increasing electric automobile is within the scope of the course continuation mileage of vehicle mounted dynamic battery, the reassembling type distance increasing unit of stroke-increasing electric automobile is disassembled, adopt the method for pure motorized motions, reduce the load of vehicle, the travelled distance of further raising vehicle, reduces the energy resource consumption of vehicle.Travelled distance needed for stroke-increasing electric automobile when vehicle mounted dynamic battery is estimated in course continuation mileage, does not then install reassembling type distance increasing unit, improves electric automobile during traveling mileage.
