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.

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.

There are over two-million front-end collisions each year, and while there is no way to know how much the predictive brake-assist system will reduce this number, it’s reasonable to assume it will help in some way. However, there is some argument that this technology will actually hurt safety. The argument is that because drivers will not understand the technology, they will assume the car will do the majority of the braking for them, and will not attempt to stop the car themselves. This argument seems absurd, but should not be discounted completely. More testing should be completed before this type of safety feature is mandated.

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.

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.

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.
