The Delphi Communiport Infotainment PC radio—nav system, e-mail device, telephone, audio system, etc.—will be available on a model year 2001 vehicle.
The Word from Delphi Automotive Systems: Electronics
“We expect that by 2005, electronics and other high tech-systems will account for 60% of our business, versus approximately 40% today,” stated J.T. Battenberg, Delphi chairman, chief executive officer and president.
Delphi created four areas to categorize the products that it is providing to the market (and not just to the traditional automotive market: in 1999, it booked $400 million in non-automotive business, with companies including Deere, Caterpillar, Harley-Davidson, and Komatsu):
Arguably (and actually), all of the categories contain electronics content.
For Safety, they are looking at the integration of a multiplicity of systems—from heads-up display to adaptive cruise control to what is de rigueur, it seems, today: onboard telematics (e.g., hands-free phone; navigation). Electronics: check; check; check; check.
Environment brings to bear systems including 42-volt architecture (see “The Word from Yazaki and JCI,”) and non-thermal plasma exhaust after-treatment.
Vehicle Integration might seem as though we are now in the area of more mechanical things, like front end modules, modular cockpits, and modular doors, but Battenberg noted, “Our electrical and electronics expertise helps us develop and deliver modular systems that meet our customers’ needs for greater flexibility, simplified manufacturing, and affordable, one-stop shopping.” (We’re not sure what that Circuit City-like reference means.)
Comfort, Convenience, Connectivity—yes, this is where the electronics really reside. Battenberg: “We have booked $2.5 billion for our mobile multimedia products alone.”
Among the multimedia line-up are the “Communiport Mobile MultiMedia Infotainment System,” rear seat audio/video that makes use of a fiber-optic linkage, and a thermal management system that adjusts the climate based on the position and body temperature of the occupant.
The implication of the Word: If you aren’t busy working electronics capabilities, you’re probably going to be passed by.
The Word from the Automotive Composites Alliance: Plastics
Specifically, they’re noting that there are new applications, such as structural reaction injection molding (SRIM) box inner panels and tailgate pieces and reaction injection molding (RRIM) box outer panels and fenders on the 2001 Chevrolet 1500 Series 4WD Extended Cab Silverado; sheet molding composite (SMC) pickup box on the 2001 Ford Explorer Sport Trac; SMC liftgate and cargo door assembly on the 2000 Ford Excursion; semi-conductive SMC radiator support assembly on the 2000 Ford Taurus and Mercury Sable; and more.
The reason for all this: the niche-ing of trucks. Vehicle manufacturers are able to provide modifications via bits, boxes and panels made of various composites with a tooling cost that is said to be as much as 50% less than what would be required for steel (as long as the volume is less than 200,000 vehicles per year).
The implication of the Word: More niche vehicles may mean more composites.
The Word from Bosch: Efficiency
Consider, for example technologies developed for windshield wiping. There is a wiper drive unit that has a compact electrical controller coupled with a reversing motor. This combination eliminates the need for the mechanical linkages necessary for conventional wiper motors, which have just one direction of rotation, to sweep back and forth.
Bosch engineers have also developed a two-motor wiper system that can be used in place of the conventional single motor. This means that the connecting rods otherwise necessary are eliminated. And the packaging volume is less than that required for a single motor. What’s more, the electronic controller used for the motors permit the definition of specific wipe patterns for specific vehicles such that if there is more than one vehicle model being built on a single assembly line, the appropriate wipe pattern can be programmed on the line.
There’s efficiency in the diesel direct-injection (DI) common rail fuel system that the Bosch plant in Charleston, SC, will begin producing later this year. The system will become available on the GM Duramax Diesel 6600 engine, which will be available on 2001 Chevy Silverado and GMC Sierra vehicles. What makes this system different is that pressure generation is independent of the engine speed; based on inputs from the electronic driver unit (EDU) and engine control module (ECM), the most effective combustion for existing conditions can be achieved.
(Not surprisingly, Bosch is working the information/entertainment/communications/multimedia area, too, not only with its own products, such as stereo gear from its Blaupunkt operation, but also with Nintendo.)
The implication of the Word: Efficiency is paying off for Bosch—its total automotive sales in North America grew in 1999 by more than eight percent to $4.2 billion.
The Word from Prospects: Safer
Everyone is familiar with the fast-down function found on most driver’s side power windows. But what about fast-up? Prospects has developed a system that it is calling “smartwindow” that can facilitate this. It’s based on infrared sensor technologies that essentially create an invisible light curtain across the window aperture. The sensor unit (the current version measures 12 mm wide and 50 mm long) is mounted in the interior door trim, opposite the sideview mirror. To assure the proper positioning vis-a-vis the window opening, the sensor’s position goes back to the sheet metal structure during vehicle assembly. Whenever the light curtain is penetrated, the window stops without having to contact anything. (There are a variety of other functions, such as allowing the window to automatically open depending on the temperature in the vehicle or close if moisture is detected. A variant of the system has been developed for powered minivan sliding doors.)
The sensor, which operates on 9-16 volt power, doesn’t require modification of existing components.
The implication of the Word: Some ’03 or ’04 models will have a new feature to brag about.
The Word from Yazaki and JCI: 42-volts
“The electronics revolution is having a huge impact on vehicle design—and vehicle electronics content is soaring. Automakers already have lots of power-hungry systems and devices on board—and there will be many more as we bring added ‘intelligence’ to vehicle systems—and offer Internet-linked cars, navigation, enhanced entertainment systems, new safety and security technologies—and more,” stated Jim Geschke, vice president of Electronics Integration, Johnson Controls (JCI), with what could be arguably considered an understatement.
To deal with this power hungriness, JCI is working with Yazaki North America to develop a 42-volt systems architecture. JCI has a 42-volt battery system, the Inspira, that is housed in what is called the Advanced Power System (APS). A key element that Yazaki is bringing to the party is its Smart Load Control Center (SmartLCC).
One of the key issues regarding 42-volt architecture is that plenty of electrical elements in a vehicle—think of lights and small electric motors—can’t deal with all of that power. Think poof!
So SmartLCC provides the means (pulse-width modulation) to adjust the power for specific devices.
Not only does the 42-volt battery have a small footprint, which means plenty of power without taking up too much under-the-hood space, but the conversion capability provided by the SmartLCC (it should be noted that there is also a DC/DC converter in the APS) means that by going with a single 42-volt system rather than a 42-volt and 14-volt arrangement, as some companies suggest, wiring harness size and complexity are reduced.
The implication of the Word: Given the proclivity of OEMs to generate gadgets, 42-volts aren’t too far in the future.
