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.

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 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 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 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.
