Smart Cars Predict Emergencies and Make Drivers Safer

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.

Robert Bosch LLC has come out with new research that found two out of three drivers don't hit the brakes with enough force just before an accident. This isn't because the driver wants the accident - it's because the overload of information and stimuli, from multiple warning systems, distracting passengers, and the mental load of processing events on the road, all compete for mental resources, and slow down the decision-making process by a few vital milliseconds. The result is the driver hitting the brakes just a moment too late, or not quite hard enough.

Bosch's solution is to implement a predictive brake-assist technology which prevents accidents by detecting, then reacting to possible accidents by activating the brakes. The technology monitors the traffic around the vehicle continuously, and determines stopping distance. The ongoing function of this technology in the vehicle's computer prepares the hydraulic brake for full-force braking when an accident is imminent.

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.

Manufacturers are already beginning to develop predictive braking technology into their new vehicles. Some, such as Cadillac, Volvo, Toyota and BMW, are currently experimenting with the technology. Others have implemented the system into their new models. Mercedes-Benz's SL550 can detect an emergency by sensing the amount of pressure the driver applies to the brake pedal, and reacts by implementing the maximum power boost.

The predictive brake-assist system is just one example of a growing body of technology designed to improve vehicular safety. Another item currently in the works is the lane departure notification system. It uses an electronic eye to detect if the car is driving within the lines. If the vehicle drifts outside the lines, the system will emit an audible warning. This technology will most benefit drivers who may be falling asleep on the road.

Continuing with the notion that drivers themselves may be the greatest safety danger they face, Bosch has proposed adding a sixth star to the current vehicle safety rating system. This new star will rank a vehicle's accident avoidance systems, such as lane departure notification and predictive brake-assist. It will help consumers evaluate how well a vehicle will help them stay safe on the road, not just how well it will withstand an accident.
