BEYOND OBDIItaken from: UNDERSTANDING OBDII: PAST, PRESENT & FUTURE by Larry Carleyhttp://members.aol.com/carpix256/library/us796obd.txt OBDII is a very sophisticated and capable system fordetecting emissions problems. But when it comes to gettingmotorists to fix emission problems, it's no more effective thanOBDI. Unless there's some means of enforcement, such as checkingthe MIL light during a mandatory inspection, OBDII is justanother idiot light. Currently under development are plans for OBDIII, which wouldtake OBDII a step further by adding telemetry. Using miniatureradio transponder technology similar to that which is alreadybeing used for automatic electronic toll collection systems, anOBDIII-equipped vehicle would be able to report emissionsproblems directly to a regulatory agency. The transponder wouldcommunicate the vehicle VIN number and any diagnostic codes thatwere present. The system could be set up to automatically reportan emissions problem via a cellular or satellite link the instantthe MIL light comes on, or to answer a query from a cellular,satellite or roadside signal as to its current emissionsperformance status. What makes this approach so attractive to regulators is itseffectiveness and cost savings. Under the current system, theentire vehicle fleet in an area or state has to be inspected onceevery year or two to identify the 30% or so vehicles that haveemissions problems. With remote monitoring via the onboardtelemetry on an OBDIII-equipped vehicle, the need for periodicinspections could be eliminated because only those vehicles thatreported problems would have to be tested. On one hand, OBDIII with its telemetry reporting of emissionproblems would save consumers the inconvenience and cost ofhaving to subject their vehicle to an annual or biennialemissions test. As long as their vehicle reported no emissionproblems, there'd be no need to test it. On the other hand,should an emissions problem be detected, it would be much harderto avoid having it fixed -- which is the goal of all clean airprograms anyway. By zeroing in on the vehicles that are actuallycausing the most pollution, significant gains could be made inimproving our nation's air quality. But as it is now, pollutersmay escape detection and repair for up to two years in areas thathave biennial inspections. And in areas that have no inspectionprograms, there's no way to identify such vehicles. OBDIII wouldchange all that. According to Mark Carlock with California's Air ResourcesBoard, the technology exists now to make OBDIII possible. "Theidea is to streamline the inspection process by only inspectingthose vehicles that really need it." Carlock says the technologyto do so is "no big deal." But he concedes that it would be themodel year 2000 at the soonest before OBDIII might actually berequired on new vehicles. A prototype system built by GM Hughes Electronics has alreadybeen evaluated by ARB that uses a roadside transmitter tointerrogate vehicles as they pass by. The system uses ultra lowpower 10 milliwatt receiver stations and 1 milliwatt transmitters(which is about 1,000 times less power than a typical cellulartelephone) with a broadcast frequency of 915 Mhz. The system isreportedly capable of retrieving information from 8 lanes ofbumper-to-bumper traffic whizzing by at speeds up to 100 mph! When the vehicle receiver hears the query signal from astationary or portable roadside transmitter, it transmits back ananswer in the form of the vehicle's 17-digit VIN number plus an"okay" signal or any trouble codes that may be present. Theinformation can then be used to identify vehicles that are inviolation of clean air statutes so a notice can be sent thatrepairs and/or smog testing is required. Or, the informationcould be used on the spot to identify vehicles for a pulloverroadside emissions check or issuing an emissions citation. The projected cost of such a system would be $50 per vehicle,says Carlock, based on similar transponders that are in use forelectronic toll collecting. The transponders are about the sizeof a small calculator. The same basic approach could also be used with existingcellular phone links (local station networks) and/or satellitesystems. To keep motorists from tampering with or disablingtheir telemetry systems, vehicles could be interrogated randomlyor on a scheduled basis to monitor their condition. The OBDIIItelemetry could also be combined with global positioning system(GPS) technology to document or monitor the whereabouts ofvehicles. Orbiting 11,000 miles above the earth's surface are 24military satellites that make up the Navstar global positioningsystem. By timing radio signals from these satellites, theposition of a vehicle, boat or plane anywhere on the earth can befixed within a few meters. The GPS system is currently used bymany fleets for tracking the whereabouts of their vehicles aswell as by onboard navigation systems for pinpointing a vehicle'slocation on an electronic map. The advantages of using a satellite based telemetry systemfor OBDIII rather than a roadside system are: * Greater coverage of the entire vehicle population for moreaccurate surveillance. Vehicles could be monitored and queriedno matter where they were, even while sitting in a garage ordriveway. There'd be no way to avoid the watchful eye of theemissions police. * Being able to locate vehicles that are in violation ofclean air statutes, either for "demographic studies" or to trackdown and arrest violators. * Being able to monitor the whereabouts of vehicles forpurposes other than emissions surveillance such as recoveringstolen vehicles (like today's LoJack anti-theft system), keepingtabs on suspected drug dealers, gang members and otherundesirables. * Being able to disable vehicles that belong to emissionscofflaws by transmitting a secret code. Law enforcementofficers might also be able to use such a code to disable avehicle fleeing from a crime scene or one that belonged tosomeone with a backlog of unpaid traffic violations. The specter of having Big Brother in every engine compartmentand driving a vehicle that rats on itself anytime it pollutes isnot one that would appeal to many motorists. So the merits ofOBDIII would have to be sold to the public based on its costsavings, convenience and ability to make a real difference in airquality. Even so, any serious attempt to require OBDIII in theyear 2000 or beyond will run afoul of Fourth Amendment issuesover rights of privacy and protection from government search andseizure. Does the government have the right to snoop under yourhood anytime it chooses to do so, or to monitor the whereaboutsof your vehicle? These issues will have to be debated andresolved before OBDIII stands a chance of being accepted. Giventhe current political climate, such drastic changes seemunlikely. Another change that might come with OBDIII would be evencloser scrutiny of vehicle emissions. The misfire detectionalgorithms currently required by OBDII only watch for misfiresduring driving conditions that occur during the federal drivingcycle, which covers idle to 55 mph and moderate acceleration. Itdoes not monitor misfires during wide open throttle acceleration. Full range misfire detection will be required for 1997 models. OBDIII could go even further by requiring "fly-by-wire" throttlecontrols to reduce the possibility of misfires on the cominggeneration of low emission and ultra low emission vehicles. So until OBDIII winds its way through the regulatory process,all we have to worry about is diagnosing and repairingOBDII-equipped vehicles and all the non-OBD vehicles that camebefore them.More on OBD 2 http://www.aa1car.com/library/ic50234.htmHome page is quite informative too! http://members.aol.com/carpix256/library/index.html Link to post Share on other sites
mike 6 Posted December 2, 2006 Report Share Posted December 2, 2006 i really dont have time to read all that, can you sum it up for me lol Link to post Share on other sites
spindat45 0 Posted December 2, 2006 Report Share Posted December 2, 2006 Basically OBD III will help the powers that be keep a closer eye on what we are up and where we are going to in our cars. Big Brother is watching!!! Link to post Share on other sites
mike 6 Posted December 2, 2006 Report Share Posted December 2, 2006 lol but if some on nicks it the have no idea where it is? Link to post Share on other sites

antera309 3 Posted December 4, 2006 Report Share Posted December 4, 2006 This seems to be aimed at US States such as California where strict anti-smog regulations are in place due to the atmospheric conditions there.However, the technology sounds very similar to that which our Government are planning to use for their beloved road pricing system.With remote monitoring via the onboard telemetry on an OBDIII-equipped vehicle, the need for periodic inspections could be eliminated because only those vehicles that reported problems would have to be tested............."The idea is to streamline the inspection process by only inspecting those vehicles that really need it.".....is contradicted by:....To keep motorists from tampering with or disabling their telemetry systems, vehicles could be interrogated randomly or on a scheduled basis to monitor their condition.i.e. some sort of periodic test would still be required, so where's the benefit?Cellular bandwidth costs more than diamond-studded gold, dipped in caviar and dusted with cocaine. Who's going to pay for all that airtime? The motorist won't pay unless there's a benefit to him. The Government certainly won't pay - they're only interested in bringing MORE money into the treasury.Being able to disable vehicles that belong to emissionscofflaws by transmitting a secret code. Law enforcementofficers might also be able to use such a code to disable avehicle fleeing from a crime scene or one that belonged tosomeone with a backlog of unpaid traffic violations.This is scary stuff. The potential for accidents caused by such a system is massive. Unless such a system can be made 100% idiot-proof, I can't see vehicle safety bodies like NCAP approving it.
