Brief description of the drawings
The invention will be further described for accompanying drawing, but the embodiment in accompanying drawing does not form any limitation of the invention.
Fig. 1 is the structural representation that one embodiment of the invention provides.
Embodiment
As shown in fig. 1, a kind of extended-range electric vehicle limping control method that one embodiment of the invention provides, first provides one
Kind extended-range electric vehicle dynamical system, the extended-range electric vehicle dynamical system include battery system 1, drive system 2, vehicle control
Device 3, A-battery 4, two-way DC/DC converters 5 and APU systems 6 processed, in the present embodiment, the A-battery 4 is 12V,
In other embodiments, the A-battery 4 can include battery from 24V specification or 48V specification, the battery system 1
Management system 11 and electrokinetic cell 12, the APU systems 6 include generator 61, engine controller 62, engine 63 and started
Machine controller 64, drive system 2 are made up of motor 21 and drive motor controller 22.
As shown in fig. 1, car key is inserted, the high-voltage switch gear of the battery system 1 closes, and the entire car controller 3 is right
The battery system 1 is detected：When 1 normal work of battery system, the battery system 1 pushes back for the height of whole car
Road powers, and the drive system 2 drives vehicle traveling, and now described two-way DC/DC converters 5 are unidirectional mode, the battery
System 1 is charged by the two-way DC/DC converters 5 to A-battery 4, and the A-battery 4 is the low tension loop of whole car
Power supply, wherein, when 12 low voltage of electrokinetic cell, the battery management system 11 is sent to the entire car controller 3
Signal, the entire car controller 3 control the APU systems 6 to generate electricity, and the APU systems 6 generate electricity toward dc bus, when the drive
During dynamic 2 electric energy deficiency of system, the APU systems 6 are that the drive system 2 is powered, and are otherwise charged for the electrokinetic cell 12, by
In described 6 responsible generatings of APU systems, it is not involved in driving.Therefore from the angle of energy-conservation, the engine 63 is controlled to pinpoint
It is operated under maximum energy-saving pattern, the power invariability that the APU systems 6 export is constant.
When the battery system 1 can not work, the entire car controller 3 keeps the high-voltage switch gear to disconnect, described whole
Low-voltage in the A-battery 4 is converted into high voltage using the two-way DC/DC converters 5 and transmitted by vehicle controller 3
To the high tension loop of whole car, the entire car controller 3 controls the generator 61 to drag the engine 63 and realizes igniting, institute
State after engine 63 is lighted a fire and be in idle state.The entire car controller 3 considers the demand of the drive system 2

The generated energy size of system 6, the APU electricity directly feed the use of vehicle whole electrical equipment, allow vehicle to continue to go with this
Sail.
Wherein, the power calculation that the APU systems 6 export is as follows：
W is the power of the APU systems 6 output, and X is gas pedal depth, and a is gas pedal coefficient, and V is speed, and b is speed
Coefficient, W0 are the power of the auxiliary equipments such as air-conditioning, the two-way DC/DC converters 5, air pump, oil pump consumption.A, b are according to vehicle
Actual conditions are demarcated.When the entire car controller 3 detects gas pedal depth X=0, illustrate that vehicle is in and stop shape
State or sliding state, the not consumed energy of driver for vehicle 2, so W=W0, the electricity of APU systems 6 is provided only to sky
The auxiliary equipment such as tune, the two-way DC/DC converters 5, air pump, oil pump uses.When the entire car controller 3 detects that throttle is stepped on
Plate depth X>When 0, electricity described in the APU is supplied to all electrical equipments of vehicle to use.The work(that the APU systems 6 export
Rate is according to gas pedal depth, speed dynamic regulation.The APU systems 6 are likely larger than in view of the demand power of drive system 2
Peak power output Wmax, so the peak power of limitation drive system 2 is, c ∈ [0,1], c is according to vehicle
Actual conditions are demarcated.
According to the extended-range electric vehicle limping control method of the present invention, cause when catastrophe failure occurs in the electrokinetic cell 12
When vehicle can not be continuing with, it can be carried using the A-battery 4 by the two-way DC/DC converters 5 for high tension loop
Power supply source coordinates APU systems 6 to realize that vehicle is walked lamely again, avoids driver and passenger original place waits assistance, save driver
And passenger's plenty of time.
Each technical characteristic of embodiment described above can be combined arbitrarily, to make description succinct, not to above-mentioned reality
Apply all possible combination of each technical characteristic in example to be all described, as long as however, the combination of these technical characteristics is not deposited
In contradiction, the scope that this specification is recorded all is considered to be.
Embodiment described above only expresses the several embodiments of the present invention, and its description is more specific and detailed, but simultaneously
Can not therefore it be construed as limiting the scope of the patent.It should be pointed out that come for one of ordinary skill in the art
