The specific embodiment
The present invention is wide in range, relate generally to be used to the automatically switch hybrid vehicle method of drive pattern of---it can be defined as comprising electric power-oil hybrid vehicle---.Usually, this switching activated at preassigned zone, and wherein this means of delivery is desirably in this zone and is driven, is driven with second drive pattern outside this zone with first drive pattern.Particularly, this first pattern is the driving that no discharging or zero-emission, anaerobic loss, no high heat produce, and such as the motor operation by battery-powered, and this second drive pattern is a combustion engine.This method comprises in principle, arranges calutron, limiting at least one doorway in this preassigned zone, and the device that further provides that this hybrid vehicle is loaded with, is used to detect this calutron.In case detect this calutron, this vehicle's drive pattern is just switched to another drive pattern from a drive pattern.
It should be understood that in this manual---
" oil " or " burning " driving engine (engine) comprises the conventional combustion engine by diesel oil, gasoline or other forms of fossil fuel/organic-fuel/biological fuel running;
" calutron " comprises any signal or the field of following electromagnetic spectrum: this electromagnetic spectrum comprises radiowave or radio frequency or infrared or laser or ultrasonic or alignment sensor (GPS) or visual identification, and any active or passive electronic equipment that moves with sort signal or field, comprise transponder, emitter, receiver, pick up camera etc.
" doorway " also is understood that the inlet of zero-emission control area or the outlet mouth of zero-emission control area (or be used to enter and leave), hereinafter, be subjected to the warehouse of air regulation will be used as this discharging controlled area-individual example.
Existence is to many possible configurations of the present invention or embodiment, especially aspect the arrangement of calutron.For example, calutron can only be deployed in the inlet or the exit in the zone that is forced to carry out the zero-emission strategy, perhaps can many calutrons of arrangement to limit this regional circumference.
As mentioned above, this calutron can be active or inactive component---such as the transponder that is placed on place, doorway, warehouse, and thus will be when hybrid vehicle enters or leave this warehouse through this transponder.For passive transponder---such as being embodied in popular RF identification (RFID) label, the work that is placed on the transponder at place, doorway does not require power supply.For RFID or passive transponder, it can obtain energy from the radiowave that is in contact with it, and generation waits to be received the machine-readable signal of getting.Like this, just suitable radio-frequency (RF) radio transceiver can be installed in that hybrid vehicle is loaded with, can be easily with radio-frequency transmissions to transponder and from the position of transponder received signal.Next the signal that receives from transponder can be programmed, so that electronic circuit on the driven mixed power means of delivery, that can carry out drive pattern and switch---for example disconnect fight to the point of combustion machine connect motor by battery-powered to continue to drive this means of delivery---.
By using this transponder to limit or mark the doorway or the circumference of warehouse or zero-emission control area, the doorway can be used as place allowance (situation warrant) and is provided with fast or changes.Except continental rise means of delivery (land-based vehicle), many features of the present invention can be included into the marine means of delivery of hybrid power.For example, in open vegetation or the travelling of the ecology in the wild zone, waste gas and excessive combustion machine noise can be driven away and treat observed insect or animal in these zones, perhaps react with volatile fluid, this transponder doorway can be migrated or oil slick drift etc. and be provided with fast or reset and put according to landform, morning and evening tides, biology, makes hybrid vehicle or boats and ships enter controlled area to endanger minimum drive pattern.
The use of the transreceiver that is loaded with except transponder and hybrid vehicle, method of the present invention also can realize by following mode: at least one radio frequency (RF) emitter is provided, and its launch site covers at least one doorway of controlled area---such as warehouse---; And at least one receiver that provides hybrid vehicle to be loaded with, it can receive the radio frequency of being launched.In case receive or detect this radiofrequency signal, described vehicle's drive pattern just can be switched to another drive pattern from a drive pattern by the electronic logic device.
The same with transponder, emitter can be arranged to certain layout, and enough quantity is arranged, to cover each doorway in warehouse, perhaps form the complete circumference in warehouse, perhaps as shown in Figure 1, with cover fully warehouse 10, with peripheral space 12 as the buffering ground region.
Fig. 2 shows the scheme drawing of the hybrid vehicle 20 with following driving transmission: this driving transmission can be controlled with automatic switching control system according to the present invention.The key of this rf control system is a radio-frequency transmitter plate 22, its parts and circuit card can be mounted in place, so that according to emitter with respect to and highly (promptly through the position of the means of delivery of this emitter, still be height of right side, window or bumper/spoiler etc. in the left side) come received RF, this also depends on the intensity or the distance of effective transmission of radiowave.
In case receive this radiofrequency signal, the logical device that radio-frequency transmitter plate 22 is loaded with just can activate or prevent (deactivate) combustion machine 24, depends on the circumstances.If driving engine 24 activated, then battery supply 26 will be prevented, and vice versa.If this driving engine activated, then usual burning can be driven and transfer to differential shaft (differential axel), thereby chaufeur can as usual drive means of delivery.A preferred embodiment of this driving transmission as shown in Figure 2, wherein producer 28 is illustrated as being permanently bonded to this driving engine, wherein, and between the burning driver stage, this driving engine also is used to turn round producer 28 so that battery 26 is recharged, and this can be regulated by producer controller 30.If driving engine 24 is prevented, then producer controller 30 can sense driving engine 24 not in running, thereby will battery 26 not charged, but battery 26 can be discharged, thereby drive the differential shaft 36 of this means of delivery with running motor 34 via discrete motor controller 32.
In Fig. 3; show the scheme drawing of the radio frequency control circuit that hybrid vehicle is loaded with; actuated signal can be launched via general I/O (GIO) port A and B thus; these ports are illustrated as being connected via optic coupler (opto-coupler), avoid the over-current or the voltage influence of parts to be activated to protect responsive radio circuit.Radio-frequency transmitter plate by hybrid vehicle and miscellaneous part are (such as the starter motor relay that is used to be connected to the high power relay of GIO-A port and is used for the starter motor (starter) of driving engine; and be used to block fuel cut engine fuel solenoid (fuel solenoid)---its circuit is connected to the GIO-B port of radio-frequency transmitter plate) between this disconnection that electrically contacts, the radio frequency receiving-member has obtained protection.It should be noted that the embodiment of Fig. 3 only shows the circuit diagram of the diesel motor that is used for hybrid vehicle.Drive the petrolic hybrid vehicle of employing for the combustion machine, can be provided to the connection of ignition system, replace fuel solenoid.
As shown in Figure 4, wherein illustrate the algorithm that between two kinds of drive patterns, automaticallyes switch, from signal emitter, that received by the radio-frequency transmitter plate, be launched via GIO-A and GIO-B port according to Digital Logic, time lag (being illustrated as 3 seconds in Fig. 4) can be set thus, make means of delivery move apart the periphery, warehouse with before drive pattern is switched to combustion pattern in diesel motor startup and battery supply disconnection.Preferred buffer distance is apart from the doorway, warehouse about 5 meters, and 3 seconds time lag can be changed according to the average velociity of means of delivery to realize the buffer distance of expectation.
Also be apparent that for those of ordinary skills, switch to take turns (toggle) or over-over mode (promptly so that be somebody's turn to do except adopting single radio frequency signal or frequency emission, when detecting this radiofrequency signal for the first time combustion pattern is switched to battery mode, reversion combustion pattern when next time detecting this radiofrequency signal, by that analogy), also the transceiving setting might be configured to handle two different radiofrequency signals or frequency, promptly, a signal is exclusively used in from combustion pattern and switches to battery mode, and second signal is exclusively used in from battery mode and switches to combustion pattern.
Another preferred feature is that a plurality of emitters are installed, and it provides lower power emission than the individual transmitter with higher-wattage emission, thereby reduces chaufeur and be operated in the warehouse and on every side personnel's health threat.
Except the hybrid vehicle that between the indoor and outdoors in warehouse, shuttles back and forth, the present invention also can be performed in the hybrid vehicle widely that alternately travels between open area and closed region, comprise airdrome luggage tractor-trailer, portable conveyer, medical care car, eco-friendly theme park passenger vehicle, city center city motor bus, support and supply with car, fork truck, goods trolley etc.To wild life conservation, dangerous substance district, disaster district or the region of war that can't stand waste gas or noise, ccasual is set or circumference or short-term doorway also are useful arbitrarily.
Also be apparent that for those of ordinary skills, revise the present invention and make it be fit to configuration widely.For example, utilize the passive transponder on mark doorway,, interim doorway can be set whenever and wherever possible by transpoder set being fixed in the column removed on mark doorway.For the buffering switch area of longer scope, that is,, can use the active transmitter responser to replace passive transponder in order to make the radio frequency of longer scope to be detected.If except detection is switched on or switched off radiofrequency signal, also will handle more signal input to judge whether that activate vehicle's drive switches, and then can adopt more complicated logic flow or artificial intelligence technology.
If require structurized signal with avoid or filter interference, electronic noise or with conflicting at operation place other form radio frequencies in vogue, then this radio frequency transmission form that can be arranged to data packet or agreement is transmitted, this data packet or agreement can be included into our algorithm, for possible loss intrinsic, institute's data packets for transmission in the radio frequency affords redress.These changes and other modifications will be considered to fall in the scope and literal meaning of following claim.
