Smart Cars Can Protect Drivers by Predicting Emergencies

When it comes to vehicle safety, automakers are a little puzzled. How can it be that vehicle-related fatalities in the U.S. have been steady at 40,000 deaths a year even as vehicle safety measures continue to improve? Is all this vehicle safety technology really making us safer? One company has announced that the problem is not with the safety of the cars - it's with the drivers themselves.

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.

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 no evidence yet to predict how the predictive brake-assist system will help reduce the over 2 million front-end collisions which occur each year, it's reasonable to believe it will be useful overall. However, some believe this technology could actually be detrimental to drivers' safety, because of the possible assumption that the car will do the braking in lieu of the driver, and the driver therefore will not attempt to stop the car on his or her own. This argument may seem strange, but can hold some validity. More research is needed before the predictive brake-assist technology can become a necessary safety feature on new vehicles.

Some manufacturers have already begun using predictive braking technology in their vehicles. Mercedes-Benz, for example, uses the system in their SL550 model. The car is able to sense an emergency based on the amount of pressure the driver uses on the brake, and then applies the maximum power boost. Other manufacturers, such as Toyota, Cadillac, BMW and Volvo are experimenting with adding the technology to their future lines.

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.

In accordance with the theory that drivers may in fact pose a safety hazard to themselves, Bosch has proposed a modification to the current vehicle safety ratings. The proposed new safety ratings would include a sixth star, evaluating a vehicle's accident avoidance systems, such as the predictive braking and lane departure notification systems. This will help consumers to compare just how safe a vehicle really is, taking into consideration how it will help them avoid accidents, not just how the car will hold up in one.
