Description
Technical field
The present invention relates to a kind of method and apparatus for being used to for vehicle to be automatically adjusted to pre-determined characteristics state.
Background technology
Very it is normally to try to make sure that all entrants' driving have the phase same sex in the motor racing match of many types
The vehicle of energy so that form gap is the technical ability of driver, and reduces the cost for participating in match, so as to even for not rich
It can also be taken part in game for abundant driver.
In order to reach these results, usually using various practical solutions in these matches, such as including to wanting
The vehicle used is drawn lots；Or the Vehicle Electronic Control Unit to be used is drawn lots；Or even should by seal
Use the mechanically and electrically subcomponent of vehicle；And when weight differences between driver may be beneficial to that body weight is lighter to drive
During an important factor for person of sailing, by the way that suitable weightening thing is added into vehicle to make state impartial.
However, all these technologies are not without limitation and shortcoming, they is realize that above-mentioned target is more or less in
Significant concession is made in their validity.
In fact, in the case where being related to manufacturing the vehicle lot being randomly assigned for the vehicle competed, it is responsible for
Preparing vehicle causes them to provide the responsibility that identical performance is entirely contest organizer.It will be participated in due to needing to set
All vehicles of match cause them all to provide identical performance, and therefore, contest organizer, which carries to use, has high cost branch
The burden of the sizable financial resources gone out.Anyway, some sometimes indelible remaining in the performance of different vehicle
Even little difference means that match relies on fortune at least in part.
Equally, the difference of the body weight of driver and body structure size will not be compensated in any way by the technology, should
Technology also lacks any ability acted on during real racetrack any vehicle operation troubles.If such failure is not
Amendment may inevitably be unfavorable for result of the match in time, and even if being corrected by the activity in box, still will
It can make vehicle in terms of its whole fixture in unfavorable.
Lot technology for electronic control unit makes the output power of engine all be phase for all entrants
With, but allow the machinery change for improving the actual performance of vehicle in the dark.Therefore, the technical requirements are carried out sternly in end of match
The inspection of lattice, to try to find out stealthily application to improve the improvement of any technology of the vehicle performance of each driver and scheme.
Equally, this technology can not compensate the body weight and size of different drivers, it would be generally disadvantageous to heavier driver.
The technology of seal is applied into vehicle machinery and/or electronic component does not ensure the performance one of institute's potted component
Cause, but allow any other change, and the morphological feature of driver can not be compensated in any way.
Weightening technology includes weighing all drivers and the body weight for most light driver's increase vehicle causes for him
For everyone vehicle plus the total weight of driver be identical.However, this technology does not ensure that the property of each car
Can be identical, because total weight is equal, the spatial distribution of element body weight may significantly affect the performance of vehicle, so that increasing
Weight technology often combines other compensation techniques.
The method of prior art described above shows that meet administration is complicated and heavy；Car can not necessarily be ensured
There is identical performance, the identical performance is useful and required so as to the most gifted driver of protrusion
Technical ability；Check that the work of the limitation forced strictly observed during match will within the relatively short time including being related to
The investigation ability of the multiple Survey Operations carried out, and the investigation then requires professional and advanced equipment；And most
Afterwards, nevertheless, still we still leave indelible unpredictable factor, such as machinery mill under any circumstance
Damage, dimensional tolerance, difference of electrical characteristic etc., this causes real racetrack state from a driver to next driver not
Together.
The content of the invention
The technical purpose of the present invention is to overcome these shortcomings.
As a part for the purpose, therefore the main object of the present invention is so that same type of one group of vehicle has
Identical performance, so as to competing each other, no matter in body weight, mechanical wear and/or any outside or inside about vehicle can
Any difference in the parameter of vehicle performance ability can be influenceed.
Therefore, the present invention, which uses, is used for adjust automatically such as the technical characteristic clearly showed that in claim here
Method and apparatus is come those results for obtaining.

Embodiment
Figure in refer to the attached drawing, in Fig. 1 reference (1) represent motor vehicles, equipment (10) is connected with motor vehicles,
The equipment is used to manage and be adjusted to pre-determined characteristics state automatically by vehicle (1).
The kart that its type is usually driven the vehicle preferably referred to herein (1) by electro-motor (2).
Due to being that the type of this vehicle (1) can be fully general as what be will become apparent below, as the drive for vehicle (1)
, therefore, can be only by the case where not limiting the invention in any way as the type of moving cell can be general
The selection of the type of this vehicle (1) is considered in example.
Equipment (10) for managing and adjusting automatically consists essentially of the input unit for inputting common physical amount (x)
(3i), the common physical amount are selected from those the common physical amounts for the inspection for being obviously served in the performance characteristic for characterizing vehicle (1).
According to circumstances, because in automobile race usually require the physical quantity, physical quantity (x) kinematics, dynamics, persistently
Property, reliability or to be related on the various combination of those aspects be probably critically important.
Therefore, can be used any with reference to physical quantity (x), the kinematics change that vehicle (1) is selected from reference to physical quantity
Amount, such as its linear velocity either the angular speed of a part in its rotating part or it may be selected from vehicle (1) or
Several physical parameters of its characteristic part, such as tire pressure or their tread depth or tire drag,
Either it more simply by being detected by suitable sensor or can be used as data item by means of any input unit (3i)
The body weight composition of the driver inputted in equipment (10).The vehicle (1) of simultaneously signalling is even detected by suitable sensor
Some parts mechanical wear degree can be used as will be examined reference physical quantity (x), be related to quality and quantity for expression
One or more vehicles (1) performance indications.
The save set (3m) being connected with equipment (10) allows the currency for preserving the physical quantity (x) checked, and by micro-
Processor mechanism (ECU) data of sensor (4) mechanism are come from by processing or signal is limited several with reference to referring to
Mark (IRN；IRR value), sensor (4) mechanism be integrated in check in equipment (10) or under any circumstance outside it but
Mutually operation therewith.
Propulsion motor of the microprocessor means (ECU) also with the vehicle (1) of the generation for checking its driving power (p1)
(2) connect, the driving power is transferred to the driving wheel (12) of vehicle (1) by drive shaft (11).
In use, the operation of equipment (10) can be described as follows.It is used to check vehicle performance using important physical amount (x)
General aspect, and the name reference that will be set as performance by value used by the physical quantity (x) under predetermined reference state refers to
Mark (IRN), the nominal reference index (IRN) is stored in the save set (3m) of equipment (10).
During the actual motion state for the vehicle (1) for reappearing the method as reference state, detect by inspection physics
Measure (x) used by be worth, define its corresponding actual reference index (IRR), it is stored in save set (3m), then by
Microprocessor means (ECU) are suitably fetched, and it is compared with nominal reference index (IRN).
When two indices are consistent or during difference with the minimum number in permissible range, vehicle (1) is considered as
Reappear under virtual condition and be not involved in nominal performance identical performance and adjusting device (10).
If on the contrary, exist between two reference indexs (IRN, IRR) non-zero or under any circumstance by suitable
Threshold value defined sizable value difference when, equipment (10) intervention and by suitably manage correlation output parameter and
The power (p1) of motor (2) is increased or decreased to adjust actual reference index (IRR), is completed all these until actually with reference to referring to
It is identical with nominal reference index (IRN) to mark (IRR).Therefore, what the reason for no matter actual performance deviates reference state be, as long as
That reason is also lasting, because suitable power adjusts, the actual performance of vehicle (1) remain valid it is identical with nominal performance.
Allow design after the adjustment more clear referring to figs. 2 and 3 the first example of the described inspection method
It is clear.
Assuming that it is vehicle straight linear motion phase on level ground for important physical amount (x) used by checking performance
Between the instantaneous velocity that uniformly accelerates.Nominal reference index (IRN) setting value is that the maximal rate obtained by vehicle (is accelerating to transport
30s is about 118km/h after dynamic startup), the value is understood as the result actually obtained by new vehicle (1), the new car
It is configured with its all elements under optimal setting state and is arranged under test mode that is optimal and suitably limiting.
For these states, Fig. 3 shows the trend of the driving power as caused by the motor (2) of vehicle (1) simultaneously
Represented with the figure of the revolutions per minute of motive power/motor (2).
Two figures of shown (being considered as what is generated by microprocessor means (ECU)) describe vehicle in figs. 2 and 3
(1) normal operation.
Contemplate it is assumed that match during, it is not intended to ground is due to less interested herein, and actual motion state is for example
Occurs the normal situation different from Fig. 2 and Fig. 3 due to the fact tire pressure declines compared with optimal reference state
State.Due to the failure, it is assumed that the actual reference index (IRR) of vehicle (1) is no longer correspond to Fig. 2 and Fig. 3 reference index,
But become the reference index corresponding to Fig. 4 and Fig. 5.That is, it is assumed that at time second time t=30, it is equal to about
104km/h。
When it happens, equipment (10) performs power adjustment, so as to increase it (referring to the motive power emphasized in the figure 7
Amendment), this improves operation curve (Fig. 6) so that vehicle (1) reappears nominal performance again, although tire pressure still in less than
The fault value of optimum value.
Therefore, although there occurs operation troubles, the driver that vehicle performance is not at unfavorable and vehicle (1) protects
Hold the competitiveness as other entrants in play.
In the example shown, with reference to run under two different conditions of two different time during match same
One vehicle (1).
The second example for being related to two different vehicles (1) refers to Fig. 2 to Fig. 7 same setting and is described as follows.
In fact, assume that two identical vehicles (1) participate in same match, it is all up to scratch in the same state, and
Therefore carrying again in this case for (identical) maximal rate of two vehicles under test mode can be for example defined as
For identical name reference index (IRN) value (Fig. 2 and Fig. 3).
Assuming that unique difference between two vehicles (1) can be due only to the different weight of driver, the driver
Respectively:It is (m1) (corresponding to Fig. 2 and Fig. 3) for the first vehicle (1), and is higher body weight for the second vehicle (1)
(m2), (m2>M1), second vehicle is because higher body weight (m2) is in the situation shown in Fig. 4 and Fig. 5.
Again in this case, the vehicle (1) with heavier driver (m2) will no longer be able to provide and refer to name reference
Mark the actual reference index (IRR) of identical performance.In fact, using body weight as the important physical amount for checking performance
(x) and input the body weight value as use input through keyboard in adjusting device (10) as input data item or conduct by setting
Standby (10) carry out the obtained survey of following detection by appropriate sensor (such as the load sensor being connected with operating seat)
Signal value is measured, then weight differences (m2-m1) must specify responsible actual reference index (IRR) and nominal reference index (IRN)
Deviation (in this case, the maximal rate for vehicle (1) or associated speed, such as axle shaft (11) again
Velocity of rotation).
Also in this case, when this situation occurs, equipment (10) performs adjust automatically, and the adjust automatically changes into
The suitable increased power (p1) (Fig. 7) of generation, this counteracts the negative of the heavier body weight (m2) of the driver of the second vehicle (1)
Effect, the driver due to equipment (10) effect in the same state as its body weight for (m1) vehicle (1) driver
Have a return match.
In view of the example provided, it is evident that check that physical quantity (x) can change according to build and source.In fact,
The physical quantity (x) can be by vehicle (1) as data item or even as one from the normal external member as vehicle (1)
The signal of partial any sensor and obtain, it is clear that it is described micro- if they are suitably connected with microprocessor means (ECU)
The processing of processor mechanism is all critically important data, operation variable and parameter to vehicle under any circumstance.
The definition of reference index (IRN, IRR) can be same general.It can be data item or data signal, or
Result of the person even in microprocessor means (ECU) as performed by suitable software with the function of processing.
In other words, by means of suitably managing and adjusting the operational factors of motor (2), it will be apparent that can be by vehicle
(1) it is real by (according to the performance requirement of actual instantaneous vehicle (1)) increase or reduction in the scope of operating range defined
The effectively pushing power (p2) and adjust and pipe to wheel (12) of power (p1) that border is provided by motor (2), i.e. vehicle (1)
Reason.
In use, adjust system (10) allows the performance calibration of vehicle (1) to specific reference state, preservation in addition
Align mode and then by the actual motion state of all vehicles (1) compared with align mode.
For the calibration of the reference state of equipment (10) and for bearing the body weight more than canonical reference body weight (m1)
(m2) for vehicle, Fig. 8, which is shown, explains the setting Dynamic correcting that permission vehicle (1) obtains and kept optimum performance to configure
The block diagram of process.
In fact and more specifically, shown module (81) shows the original state of vehicle (1) in fig. 8, wherein,
It is presumed to be set to nominal standard power state.
With in the subsequent step shown in module (82), driver enters in vehicle (1).In subsequent step (83), inspection
Survey and measure the body weight of driver and/or the acceleration of vehicle.
Module (84) visually shows the step of inspection system (10) obtains relevant information with it, is connect in module (85)
And the relevant information is handled to obtain the power value (p1) that motor (2) must will be provided actually.If prove relevant push away
The performance for entering power (p1) is suitable and/or is acceptable, and vehicle setting process will be terminated with module (86).
If it not, feedback module (87) will back to system (10) to readjust the mould of the adjusting parameter of motor (2)
Block (83), after this, step (84), (85), (87) and (83) is performed by circulating, vehicle (1) repeatedly reconfigures directly
To obtain even for for the vehicle (1) with body weight (m2) under reference state as close possible to the car with body weight (m1)
The actual thrust power (p2) of the power (p1) of (1).Once these have reached, adjustment process is tied in module (86)
Beam.
