Safety and light weight cars

In order to reach the upcoming CAFE standards, cars will be smaller and they will be made of lighter materials. Safety devices via electronic systems may help consumers gain confidence in smaller, lighter cars.

If you have antilock brakes, it is worth experimenting with them and understanding how they work under different conditions.

Almost all antilock brakes do turn off by pumping the brake pedal.  If you are in a situation where you don't want antilocks to "work", pump the brakes quickly yourself, then do whatever you want.  This will turn off most antilock brakes.

Pressing the brakes (not pumping them) is the proper way to stop with antilock brakes.  This allows the ABS system to start pulsating if wheel lock occurs on one or more wheels.

William K: It surprised me last December when the National Transportation Safety Board called for a law that would prevent phone usage by drivers, and the response was so negative. It wasn't the electronics manufacturers weighing in, but the consumers. They were writing to newspapers and calling radio talk shows to make their case of the need for cell phones in the car. Unfortunately, it seems that drivers, especially younger ones, just can't put their phones down.

I agree, Rob. Electronic safety systems will have a positive effect. It's been said that approximately 90% of accidents are caused by some kind of driver error.

That stat sounds about right, Chuck. Yet, if you're not driving a big SUV, and you get hit by a big SUV, your chances of injury are elevated. Any electronic devices that can help ameliorate this situation would be very helpful.

Yes, it is true that most of the accidents are caused by driver error, and the main driver error is not paying enough attention to driving. Probably 80% of all of the accidents are caused by inadequate concentration on the driving task, which of course willm indeed lead to errors in actions. When the radios only had 6 buttons to select stations drivers were much less distracted then when it takes several button selections to get a specific station. But the complex radios sell for a whole lot more than the old ones, so the profit is much larger. So probably radios won't get any less complex, although more controls will go to the back side of the steering wheel. This allows tuning without looking but the distraction is just as great. The problem is in the break in attention, not in the time looking at things. At least some of the times that is the problem. So removing the need to look at things is only a small partial solution.

I think the key is to have the computers help the operator to make decisions faster, with greater information.  Being sure not to have the computer make the final decision.  Because occasionally all of the data may point one direction while a human can decide that is still the best course.  What would have happened in New York if the computer had tried to get to the runway rather than that pilot putting the plane down in the Potomic.  Possibly a very large disaster.

The good news is that we are reaching that point very quickly. The three main pieces of the active safety puzzle -- adaptive cruise control, lanekeeping and crash avoidance -- are already in use.

What makes this movie stand out from the typical high school sports story is that the teenagers are undocumented immigrants, and the big game is a NASA-sponsored marine robotics competition. Like many other Hollywood movies, however, Spare Parts only tells part of the story. What the film shows -- and doesn’t show -- raises important issues affecting STEM education in the US.
Instead of sifting through huge amounts of technical data looking for answers to assembly problems, engineers can now benefit from 3M's new initiative -- 3M Assembly Solutions. The company has organized its wealth of adhesive and tape solutions into six typical application areas, making it easier to find the best products to solve their real-world assembly and bonding problems.
Load dump occurs when a discharged battery is disconnected while the alternator is generating current and other loads remain on the alternator circuit. If left alone, the electrical spikes and transients will be transmitted along the power line, leading to malfunctions in individual electronics/sensors or permanent damage to the vehicle’s electronic system. Bottom line: An uncontrolled load dump threatens the overall safety and reliability of the vehicle.
