| Vehicle safety is a puzzling issue for automakers. Despite improvements in vehicle safety measures, vehicle-related fatalities in the U.S. have stayed the same over the years, with about 40 000 deaths a year. Why are fatalities continuing at the same level despite technology which makes cars safer? One suggestion is that it's not unsafe cars that are responsible for these deaths - it's the unsafe drivers behind the wheel. According to research from Robert Bosch LLC, two out of three drivers do not hit the brakes hard enough before an accident. This is not because he or she wants the accident, but rather because of the human condition. Multiple warning systems, distractions from passengers, and processing the events on the road can cause the decision-making process to take milliseconds too long. These overwhelming forces can impair one's ability to slam on the brakes in time, or with the correct force. The solution, according to Bosch, is a predictive brake-assist technology that will detect an anticipated accident and react by activating the brakes. The system will continuously monitor the surroundings on the road to determine stopping distance. With these calculations constantly running in the car's computer, the hydraulic brake is properly engaged for full-force braking once an impact is evident. Although there's not enough research yet to know for sure, it's reasonable to think the predictive brake-assist technology will be useful in preventing some of the over 2 million front-end collisions that occur every year. However, some argue that this technology might actually decrease safety, because drivers might not fully understand how the system works and erroneously believe it will do most of the braking for them. They then might not try to stop the car themselves, increasing their risk of accident. This argument seems inane, but shouldn't be completely dismissed. More research and testing are needed before this system can be made mandatory. Some manufacturers are already using predictive braking technology. Mercedes Benz has implemented the system in their SL550. Based on the amount of pressure the driver places on the brake pedal, the car is able to sense an emergency and apply the maximum power boost. Many other manufacturers, such as Toyota, Volvo, Cadillac, and BMW are also testing the technology. The predictive brake-assist technology is only one new electronic system to improve automotive safety. In addition to Bosch's proposed predictive brake assist technology, there's also something called "lane departure notification." Simply stated, lane departure notification uses an electric eye to determine if the car is driving outside the lines. This system would most benefit drivers who may be falling asleep, as driving outside the lane will trigger an audible warning. In keeping with the idea that drivers themselves can be a safety issue, Bosch has also proposed modifying current vehicle safety ratings to include a sixth star. The sixth star will be used to rank a vehicle's accident avoidance systems, such as predictive braking and lane departure notification. It's a good way for consumers to compare a vehicle's complete safety rating, rather than just its crashworthiness. |
