(Hybrid vehicles) Automotive Engineers Help Save Lives And Cash
No commentsBy Mike Trudel
It turns out all those fancy automotive safety devices cannot only help save lives, they can also save cash. According to The Economic Impact of Motor Vehicle Crashes, roughly $230.6 billion was exhausted on motor vehicle crashes in 2000 in the U.S. Nearly 42 thousand people perished that year, and 28 million vehicles were damaged.
The same government report also revealed that 5.3 million individuals suffered non-fatal injuries, 39% of all traffic-related deaths were attributed to alcohol and such substance-induced accidents cost about $51 billion. Public tax revenues, amounting to $21 billion, paid the costs incurred by 9% of crashes. That’s $200 for each household in America.
But wait. There’s more. Lost market productivity was estimated at $61 billion, property damage at $59 billion, medical expenses at $32.6 billion and the cost of travel delays at $25.6 billion. Each fatality produced a discounted lifetime cost of approximately $977,000.
Active and passive safety systems developed by automotive engineers and their colleagues may be a bigger part of the answer than we might suspect. Systems currently being developed are addressing both the monetary and safety concerns of our roadways through devices that have automatic responses to dangerous conditions or events. For instance, adaptive cruise control adjusts the speed of the vehicle to maintain a preset time gap from the vehicle ahead. Active night vision uses infrared illuminators to help drivers to see better when driving at night and electronic stability control improves the safety of a vehicle’s handling, helping the driver maintain control of the vehicle.
Surprisingly, perhaps, these are just basic safety features - ranking amongst car navigation systems, keyless entry and hybrid cars as, yes, technological innovations, but old news to vehicle manufacturers. Lane departure and forward collision warning, pre-crash mitigation systems, side alert, pedestrian and road sign recognition systems are part of the new wave. These systems “read” the road using electronics, cameras and sensors. They alert drivers when they are drifting out of the intended lane, have another vehicle in their blind spots, are in danger of crashing or are distracted. These technological gems even respond to unavoidable crashes by enacting safety precautions, such as pretensioning motorized seat belts and applying brakes during the last 400 to 500 milliseconds before a crash, when there is little a driver can do to stop it.
According to the National Highway Traffic Safety Administration (NHTSA), 50% of all crashes involve “driver inattention.” It’s impossible to pinpoint how many crashes could have been avoided if there had only been some alert system warning drivers to pay more attention during critical moments. How many crashes could have been avoided by a single alert, some notification that another vehicle was in a driver’s blind spot? By shaving off four or five miles per hour before a crash by applying the brakes?
And while saving lives and preventing injuries is of the most concern, we cannot, in all reality, ignore the financial repercussions of roadway accidents. Billions upon billions of dollars are lost every year because of these crashes. Medical expenses, property damage and lost productivity are passed on to the average citizen in the form of higher taxes and insurance premiums. What if some percentage of this cost - even if slight - could be lessened by safety systems? One percent of hundreds of billions of dollars, after all, is nothing to scoff at.
Automotive engineers are critical contributors to advancing projects with aspirations of making roads safer. Without their expertise, none of the technology currently available would have been possible and neither would future innovations. What’s more, these talented individuals are integrating these devices so they are more affordable and, thus, more accessible to the masses.
In the near future, a modestly priced vehicle could have a myriad of safety features - forward collision and lane departure warning, road sign and pedestrian recognition, adaptive cruise control, pre-crash mitigation, electronic stability control, side alert. All of it. So kiss some automotive engineers today - hiding in their offices - and tell them you’re proud. They could just save your life … and at least a few bucks on your insurance policy.

Troubleshooting a BMW Transmission that Will Not Go Into Reverse
By Astonish Articles
An automatic transmission is just that- automatic, consequently most people tend to pay very little attention to it until a major problem rears its ugly head.
Picture the scenario- you are driving along in the lap of luxury, the satellite radio blaring and the heated seats on. You have become accustomed to the comfort level and great driving experience brought to you by BMW.
You decide to stop at the local convenience store on your way home to grab some ice cream for the kids and a bottle of water for yourself. Upon returning to your car, you start it up, check your rear view mirror, put the shifter in reverse and then the unthinkable happens- the engine just revs as if it is in neutral and the car goes nowhere!
This article deals with the reasons behind an unexpected loss of reverse in certain BMW automatic transmission equipped vehicles, specifically the 3 series and 5 series vehicles that use the ZF5HP19 or steptronic transmission. This includes the popular 323i, 323ci, 325i, 328i, 330i, 525i, 528i, 530i, X3 and X5 models well as some others built in the 1999 to present model years.
To eliminate confusion, this does not apply to vehicles equipped with the GM 5L40 E transmission, just the ones with the sometimes problematic ZF5HP19. The 5L40 E has some issues of its own that are beyond the scope of this article but are certainly going to be the subject of another.
The failure rate for these transmissions seems to be very high and is expected to become much more of a problem as time goes by.
Typically, the vehicle is working perfectly while driving forward but when it is put in reverse there is a complete and permanent loss of movement to back up.
Reverse is typically a major feat for any transmission to accomplish- imagine the demands that are placed on a gearbox as it is asked to reverse the torque of your engine so that you can back up your nearly 4000 pound vehicle.
By far, the most common cause of the reverse problem in BMW’s is the failure of the D-G clutch drum. Specifically, the snap ring that retains the D or reverse clutch breaks out of the clutch drum resulting in an inability for the clutch pack to apply.
The good news is that there is hope in regards to a proper repair. The factory has released an updated part that so far appears to be a permanent fix for this problem.
In our testing and in conjunction with several hundred successful repairs at our facilities, the new part seems to be metallurgically superior in several ways.
We have found that there is an improved radius area as well as slightly thicker casting. In addition to this, the grove that retains the snap ring is also relocated further away from the edge of the drum.
With this issue addressed and attention to detail in several other areas of the ZF5HP19 unit, the transmission can be repaired to “better than new” condition by a competent transmission rebuilder / remanufacturer. In fact, when properly repaired, the ZF gearbox becomes quite robust and can provide an almost indefinite service life.

Drive-In Theaters Or Driving Theaters? Today’s On-Board Vehicle Entertainment
By Mike Trudel
There was a time when a static-filled sound box and a bag of greasy drive-in popcorn had to suffice for vehicle theater entertainment. Today’s vehicle manufacturers have taken the theater experience of yesteryear and brought it into the 21st century with a virtual in-car entertainment system. Portable device interfaces, media players and satellite television are just a few emerging technologies for an automotive engineer to consider integrating as an attractive magnet for potential car buyers.
Portable Entertainment
Functionality and integration of portable entertainment has become more than just a feature for luxury vehicles. Portable device interfaces allow drivers to access their home music library or a video game via their automotive system using a USB port. MP3 players connect directly to a vehicle radio and allow control of music selection while song title, artist, album and elapsed time are conveniently displayed on the radio. SD Card Playback, a navigation database interface, can also be used to bring music into the vehicle.
That’s Infotainment
With the advent of media players, today’s driver can integrate a variety of entertainment and information content to his or her preference. Music from multiple sources can be searched and played using a single interface. And those interfaces are controlled via voice, soft keys, a central control knob or steering wheel controls. Want to hear only reggae or pop while driving home from work? A “Similar Songs” button looks into the database and selects similar songs for play. Other media player features include Bluetooth (R) audio streaming, DVD-V/ROM, MP3 and full-featured navigation capabilities.
Best Seat Isn’t Even in the House
“Are we almost there?” is likely to turn into “We’re here already?” for those who discover the best seat in the house is at the rear of a vehicle. Rear-seat entertainment allows passengers to enjoy movies, music and video games via an LCD color monitor, which offers a crisp and clear picture, even at extreme viewing angles. Factory-installed systems include a DVD player, which forms the core of the system and can also read music, data files and photos. Illuminated keys let the viewer keep control of the DVD player, even in the dark.
After short journey breaks or after the engine has been switched off, a special module enables the system to know exactly which content was played last - so users do not have to go searching through the last film or music program.
Soon, consumers may also begin to see video/wireless systems that deliver separate options for the driver, front-seat passengers and the rear-seat positions. Drivers might listen to satellite radio, while passengers separately employ headphones to listen to MP3 players or watch DVDs.
TV on the Open Road
Satellite television allows passengers to leave DVDs at home and instead enjoy digital-quality entertainment channels on the open road. Various systems can provide access to more than 100 programming channels and more than 50 channels of satellite music. In addition, families can catch the big game, traffic reports or local news stories from the comfort of their vehicle via local networks. Satellite TV also integrates with various in-vehicle backseat video systems.
Popcorn Optional
Today’s on board car entertainment system provides seamless experiences in music, movies, television and more. Greater freedom from home to the open road means access to entertainment, navigation and safety features from behind the wheel. With all of these options, drivers may discover the best seat in the house is actually parked out in the garage.
