Smart Cars Predict Emergencies and Make Drivers Safer

Vehicle safety is something of a puzzle for automakers. Improved vehicle safety technology have made cars safer than ever, yet the number of vehicle-related deaths in the U.S. has remained steady at 40 000 fatalities each year. Why haven't all these new vehicle safety measures made us safer? One company has hypothesized that the problem lies not with the cars, but rather, with the drivers.

New research from Robert Bosch LLC suggests that two out of every three drivers don't hit the brakes hard enough before an accident. This doesn't mean the driver wants the accident - it's simply the nature of the human condition. During an accident, a multitude of things are competing for the driver's attention, from multiple warning systems going off and distractions from other passengers, to the simple act of processing what's going on in the surrounding environment. All these combined together can delay the decision-making process a few milliseconds too long, and impair the driver's ability to hit the brakes fast enough, or with enough force.

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 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.

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.

Predictive brake-assist technology is just one of many new technologies aimed at improving automotive safety. A lane departure notification is another new development which will protect drivers. It uses an electric eye to monitor the vehicle's position in relation to the lines on the road. If the vehicle starts driving outside the lines, the system will release an audible warning, which could greatly benefit drivers who may be falling asleep during long drives.

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.
